BHO Extraction

BHO Extraction

What is BHO Extraction?


BHO (Butane Hash Oil or Butane Honey Oil) is a concentrated cannabis extraction known for its high cannabinoids concentration, reaching up to 90%. The concentration depends on the strain of the cannabis  flower.
This makes BHO extracts some of the most potent marijuana concentrates globally. BHO extracts are used to create various products, including topical treatments, vape juices, edibles, and more.

 The BHO Extraction Process

BHO extraction involves using a high-purity butane gas to separate cannabinoids and terpenes from the raw cannabis plant material. During the BHO extraction process, butane gas passes through cannabis in a sealed cylinder, effectively extracting these valuable compounds. The raw extract’s golden color and viscous texture can be further processed to create different products like shatter, budder, and wax.

BHO extraction uses hydrocarbons as a solvent to extract resin from the cannabis plant. This resin, known as butane hash oil, or shatter, consists of purified cannabinoids and terpenes. Compared to other extraction methods, BHO extraction captures a comprehensive profile of cannabinoids, THC, terpenes, flavonoids, phenolic amides, and sterols, representing the original plant in a concentrated form.

Why Choose BHO Extraction?

Professional extraction companies prefer instrument-grade butane for its purity and low boiling point, enabling more complete cannabis extraction than solvents like carbon dioxide or ethanol. Properly conducted BHO extraction results in higher cannabinoid content, a broader terpene profile, lighter color, and better flavor compared to other methods.
Another important factor affecting the decision of the extraction process is the price. The price of BHO extraction is lower compared to other extraction methods, especially supercritical CO2 extraction.

When butane gas contacts the cannabis plant during BHO extraction, it extracts THC and terpenes from the plant matter. This process can produce different textures, ranging from oils and waxes to hard, brittle forms like shatter.

The Advantages of BHO Extraction

BHO extraction, when executed with professional equipment in a certified lab, offers numerous advantages:

  • Efficiency in cannabis extraction
  • Cost-effectiveness
  • Safety in commercial extraction
  • Great-tasting final products
  • Safety and enjoyment for consumers 

Safety is an aspect that has to be considered. BHO extraction is very safe when all the safety regulations are applied. Besides having the equipment that is safe and tested,also the operator has to be educated on proper and safe use of the extractor.
You can find extractors on the market without any certificates and without safety measurements prepared for safe use.

These benefits explain why many consumers prefer BHO extracts and why businesses choose Exeat extractors for their BHO extraction needs. Exeat extractors can be custom-made to meet specific demands, with options from our regular offerings.

The Role of Closed-Loop System in BHO Extraction

Modern BHO extraction methods are incredibly safe, utilizing closed-loop systems that capture and recycle residual butane, preventing gas leaks and ensuring no butane is left behind. Commercial-grade closed-loop systems contain all flammable solvents, minimizing the risk of explosions and allowing for solvent recycling. This process is safer, more controlled, and more effective than open-loop extraction.

In closed-loop BHO extraction, butane is loaded into a pressurized tank, and the cannabis is placed in an extraction tube. Clean, odorless, and tasteless butane passes through the plant, extracting terpenes and cannabinoids.

Exeat produces closed loop extractors Extractors can be  customised to fit individual needs or can be bought prebuild. They are produced according to relevant standards and approved by independent third party inspectors and institutions.

BHO Extracts: Use and Processing

BHO extracts are primarily used to create concentrated oil for vaporization cartridges or as dabbable concentrates sold by the gram. The oil can also be activated and incorporated into edibles, topicals, or distilled. Proper storage is crucial to maintain the potency and flavor of BHO concentrates, which can last for a year or more if kept in a cool, dry, and dark place.

Decarboxylation, Dewaxing, and Winterization

BHO concentrates require decarboxylation, the process of heating the substance to activate chemical acids into their parent cannabinoid compounds. Heating cannabinoid acids like THCA and CBDA converts them into the therapeutic THC and CBD compounds. Consuming raw BHO is not only dangerous, but also won’t contain any activated compounds. Without decarboxylation consumers will not feel the effect of the cannabis or hemp plant. 

Dewaxing is the process of removing waxes and lipids from the final extract. Waxes and lipids can speed up the nucleation process and significantly affect the flavor and smoothness of the concentrate. 

Winterization is one method of de-waxing. During winterization, BHO is dissolved into a polar solvent, usually ethanol, at sub-zero temperatures. The cold temperatures force lipids to the top for streamlined filtration.


BHO extracts and concentrates are popular due to their accessibility, portability, and versatility. They provide a user-friendly experience with various consumption options, making them suitable for different needs and preferences. BHO extraction, with its full spectrum extraction, addresses consumer demands better than other methods, offering a fast and efficient way to produce highly potent cannabis products.

While there are risks associated with BHO extraction, proper execution in a controlled environment ensures safety and quality. Partnering with a trusted provider like Exeat ensures you leverage the best in BHO extraction technology. Our machines have certificates to comply with the most stringent norms.
Instruction manual should be followed besides your state laws and the ATEX directive 2014/34/EU.

Terpenes in hemp flower

Terpenes in hemp flower


We will explain what are terpens in hemp flower, what are the most known terpens, their qualities and usage.
We will also explain the correalation between terpens and cannabinoids. And for the end, we will tell you more about terpene preservation in vacuum infusion with cannabinoids. 

hemp flower

What is hemp

Hemp (Cannabis Sativa L.) is a broadly grown plant worldwide. In the last years, the cannabidiol (CBD) and terpenes in hemp have had increasing research interest due to their human health benefits and pharmaceutical values.

There are two types of hemp plants:

  • the fiber type;
  • cannabinoids type hemp plant:  rich in cannabinoids.

Depending on the level of tetrahydrocannabinol (THC) in the plant, the hemp can be further classified into industrial hemp (THC < 0.3%) and marijuana (THC > 0.3%).

What are terpenes

Terpens are  organic, aromatic compounds found in plants in the form of oils. Essentially they are what gives a plant its unique flavour and aroma.

 The most distinct characteristic of terpenes is the smell, which depicts the unique aromatic characteristics of hemp plant and is used by the plant to repel and defense against herbivores, attract pollinators, and inhibit the microbial growth.

There are currently more than 120 terpenes already identified in hemp.  Terpenes are found in lots of fruits, vegetables and herbs and are recognized as safe for human consumption. Terpenes are used in a wide variety of foods and cosmetic products.

 These fragrant oils are responsible for each strain’s unique smell and taste, but they also have a range of physiological and therapeutic effects. Such as anti-anxiety, pain-relief, relaxation promotion, anti-inflammation and antimicrobial activities.

The difference between cannabinoids and terpenes

What gives hemp its “character” are the hundreds of chemicals it contains. Among them are cannabinoids, terpenes and flavonoids. 

While terpenes don’t get you high, they do influence the effects of other plant compounds such as THC and other cannabinoids.

Most common terpenes found in hemp


Most common therapeutic effects and benefits found in terpenes are:

  • antiviral,
  • antidepressant,
  • pain relieving,
  • anticancer,
  • antimicrobal. 



One of the most common terpenes found in cannabis is myrcene. Myrcene is also found in hops and is responsible for the peppery, spicy, balsam fragrance in beer. It’s also expressed in lemongrass. Myrcene is a potent analgesic, and has great antioxidant and anti-inflammatory activities. 


The terpene caryophyllene is present in many herbs and spices, including black pepper, basil, and oregano, and cannabis strains with high levels of it deliver a spicy, funky warmth to the nose, similar to cinnamon and cloves. Caryophyllene is an excellent analgesic agent and antispasmic in muscles. 


Linalool refers to two enantiomers of a naturally occurring terpene alcohol found in many flowers and spice plants such as lavender.  Linalool is a colorless oil. Linalool shows sedative, anti-influenza, antimicrobial and neuroprotective effects


Pinene is an aromatic compound commonly found in cannabis that smells a lot like a forest of pine trees. But pinene can bring more to a strain’s experience than just flavor. Pinene has memory improvement, anti-inflammatory and anti-microbial functions.


Limonene is a colorless liquid aliphatic hydrocarbon and is the major component in the oil of citrus fruit peels. Limonene shows good antiviral, anti-bacteria and antidiabetic properties.


Terpinolene is found in lilacs, nutmeg, cumin, and apples. 


The subtle earthy, woody and spicy notes that give hoppy beers their distinct taste and aroma are also partly responsible for giving cannabis its unique scent. Hops and cannabis share a common terpene: humulene. It is very similar to Myrcene.


Eucalyptol has a fresh mint-like smell and a spicy, cooling taste. It is insoluble in water, but miscible with organic solvents. Eucalyptol makes up 90% of eucalyptus oil.


Terpineols are monocyclic, monoterpene tertiary alcohols that are naturally present in plant species. It has a pleasant odor, similar to lilacs, and is a common ingredient in perfumes, cosmetics, and aromatic scents.


Ocimene is the terpene responsible for some of the sweet and herbaceous flavors of certain cannabis strains, and it can also add citrusy and woody undertones. It may also offer a wide array of medicinal properties, as well as uplifting effects.

How can terpenes affect the effects of cannabis?

Terpenes can enhance or alter psychoactive and medicinal properties of hemp. This phenomenon is know as “entourage effect”.
It can be thought of as working as follows: the sum of all the compounds present in cannabis is greater than the sum of its parts. In other words, a special synergy of the whole plant occurs when cannabinoids and terpenes are consumed together, as opposed to when they are consumed separately.


Preserving terpens 

Preserving terpens while using processing technologies to enrich the quality and compound of hemp is of great importance. Achieving high processing efficiency with minimal loss of bioactive compounds is necessary to ensure the quality and safety of hemp plants after harvest.

With vacuum impregnation machine API 3.0, it is possible to have an effect on cannabinoids composition and concentration, without altering the terpenes.  That means that you can infuse hemp flower with our API 3.0 machine and preserve the terpenes.  Without terpenes, cannabinoids would be far less effective, and far less flavorful.

Meet the founders of Exeat

Meet the founders of Exeat

Meet the co-founders of Exeat, Aleš Njegovan and Igor Škrjanec 


Meet the founders of Exeat, Aleš Njegovan and Igor Škrjanec..

What started with two entusiasts, grew into designing, constructing, building and testing their machine, extractor. The research and development was fueled by market demand. Soon it was followed by constructing and building Vacuum Imprengnation API and after a freeze dryer. We talked about their beginnings, plans and vision.

Aleš and Igor, founders

Aleš on the left and Igor on the right, standing next to their Vacuum impregnation machine.


How did you start the company?

Igor: It started on the basis of extractions, the need for processing the flower began to appear. This was something not developed, researched on the market. The market demand was high. But at the time there was a lot of people trying to apply cannabinoids to the flower, but not many knew exactly how to do it. And the results they had, were not good. 

What materials?

Igor: These were the various analogs of psihoactive cannabinoids. But the goal was to have a high quality while trying to lower the price of final products. Indeed, there was a need to enrich the flower, but there were problems with application. Manufacturers of machines had different ways, but the result was extremely dark and sticky flower which was not of good quality. This was the reason that we started thinking about how to make a better solution with better results.

pressure test
working on API

How did you get into extractions?

Igor: I was already involved before, since 2015 I started dealing with super critical extraction, CO2 extraction.

Then we discovered  that it is not sustainable. So we went back to butane again, and we based this coating on butane as well, because we saw what it was capable of as a solvent. And we assumed that this could be the solution to all these problems. It actually turns out to be a super solvent.

Aleš:  Starting from extraction, in fact, infusion as such was born. As a reverse extraction process. With Igor we met because of the extractor. So then we got to coating and spraying the flower. But this was not the best solution. And the next step was to solve this problem. We both kind of looked towards this market. I have already developed some products with an extractor by then.

Did you then see another opportunity on the market?

Aleš:  We began monitoring cannabis market, which was growing at that time, in fact it is still growing. And we said that they will try to find some solutions. And Igor is more than the ideal person for the development of new products, because he has a deep understanding and knowledge of in terms of technical and practical matters. I may have had a nose for it at some point that, I started just pushing that we should develop this product.

What about your professional background, Igor?

Igor:  I’m a chemist, majored in biochemistry. … But more than that, I mean definitely this is the  knowledge, which I definitely need to work in this industry. But what I also see as important or even more important is the  experience and the knowledge gained in this professional life, without it, certainly we wouldn’t be able to put the machines together.

Did you always see yourself starting your own business?

Igor: It was in the back of my head. Starting something of my own, doing something on my own.

What are the values ​​of your company? 

Aleš: Our core values are products of highest quality that answer to the markets needs. Client service. Fair play. Working with like-minded people. Teamwork. Being fast and flexible and innovative. Working with passion.

Because you have to be prepared to completely change the direction and take up another matter.
Through the development that Igor is now in charge of, this is exactly what is been happening. A new step is always being taken, with a view to the future. We are a lean company.

detail API

Where do you see yourselves and your company in five years?

Aleš: In 5 years we will still be here in this company, but with coworkers and new products.
I do not want to stay only in cannabis industry. Our aspirations are higher. We would like to work in other industries aswell. Like food, cosmetic, pharmaceutical industry. We will not stay only in the cannabis market where we made the breakthrough.
Even this market has its own limits. If you don’t come at the right time with a product that is a breakthrough product, which the new vacuum impregantion machine really is, nothing big can happen.

We want to succeed in establishing some sustainable production on the extractor. So that we could talk about being an intermediary between producers of certain plants. Will it be for cosmetics or for pharmaceuticals. We want to produce some essential oils here.

Igor: I have the same vision. I will be leading research and development. Having more employees, products, growing steadily but constantly.

But our main goal here from the start was not only cananbis industry. Regrading the extractor, the focus is on services, on all the plants.         


How long does it take to build one machine, from start to finish, to assemble it?

Igor:  The main thing was that as many of these series of machines were made, each one was upgraded. When the decision is made to go into production, all the documentation is first checked and corrected. Then, on the basis of this, the material begins to be procured, and the agreement with the welding shop proceeds in parallel. Then there is the process of welding, final inspection and certification. After the certification itself, there is still the assembling of the machines and at the end the test When the machine is assembled, certain things still need to be checked, and that takes… How much? Hmm. I would say that the whole process take about three months.

Aleš:  Each upgrade actually just adds more of this manual work to get the thing done. Each upgrade just added a new piece, which was basically simpler than actually upgrading. From the sprinkler itself, to the filter and additional valves. Each upgrade entails additional hours of work. And in preparation, in welding, in workshop work.

Did you develop any new addtitions to Vacuum impregnation machine?

Igor: We offer heater. This addition significantly (by half) reduces recovery time. The solvent is recovered much faster and can be used in another cycle..
We also offer some upgrade to ensure safe work. This is butane gas detector. In case of a presence of butane the operator will get visual and audio alarm when Exeat ventilation system is installed. Besides that  the detector will trigger ventilator and in case of dangerous concentrations of gas all the electrical consumers will be disconeted. Leaving only ventilator work on 100%, full capcity.  

Is there a plan for the future to develop a fully automated machine?

Aleš:  At one moment the market demand was for really big quantaties of  infused flower.  For larger volumes, it was logical to think about automating the machine. But the development of fully automated machine is on a pause for now due to the market situation. Because at the moment it is not known in which direction this entire market will go. The market is special, it has its own peculiarities, and despite the fact that Igor started working on this project, I think that now it is somehow taking a back seat. For some time.

Will you think about getting an investor?

Aleš: Yes, we already had some prospects.
Potential investors for such machine could be outside of Europe. There is a big potential for this machine. Now we are thinking more and more in the direction of other uses of our infusion machine.
Because now we have a really good system and the question is where the usefulness of this machine can be found. 

And where do you see the possibility of this?

Aleš: The food industry is one option.  For example we could be infusing tea. Because today we know that everything that is found in some tea filter bags is not just some organic substance. We all know that flavors etc. are added.

How do you manage all the operations at your company?

Aleš: When we have time to stop, and when we start to think, we envision. But the problem is that the work, and day to day operations consume you. We have to visit fairs, build the machine, order parts, teach the customers how to use the machines, attend meetings etc..

What are the qualities you are looking from your future employees?

Igor: The future colleague must be ready to work in different areas, because we are a small company, he has to be flexible. Prepared to learn, this part is definitely extremely important. First and foremost, we will be recruiting and looking for someone from the field of mechanical engineering. For the purpose of construction, for the purpose of searching materials, procurement of materials, verifiying material, quality and then partial monitoring of production and conclusion then with the inspector.

We want to set some priorities sorted for us. What we do, what our coworker does.

detail API

 Where are your target markets right now?

Aleš: In fact, we managed to generate enough sales in the regional area of Eastern Europe. And some in the US. But actually we have sold most of our products to the surrounding countries so far.

In Europe, Switzerland is unknown, it is an interesting market. Germany also.

We would like to explore more Europe, while at the same time we are also exploring the market in US and in Africa.

What is a profile of your customer?

Aleš: I think that these are modern businessmen who have created legal businesses in this market and got wealthy. It is missed conception that our buyers are users of cannabis products.

It is indviduals with a clear business interest who can see a business opportunity.

Igor: it is business men that work in niche market. And who succeeded by working on our machines.

Are you proud of that?

Aleš: We pride ourselves on giving them the tools to reach their business goals. Among these entrepreneurs, we have individuals who after also bought a second machine.

Untill we entered the market, neither of us had a sense of how the market works and what quantities are being sold.

Igor: We were surprised at the quantittes. And  the demand is still growing.

How do potential customers find you?

Igor: We find them and contact them. And thy meet us on fairs. Or they hear about us.

Was it a difficult decision to leave your previous job and start a business?

Igor: I was fully occupied at my previous job. But at the same time I was fully occupied here. And it is difficult to sit decently on two chairs. It doesn’t work. So something had to be done.  And so many new prospects were opening up for Exeat.

Aleš: If Igor hadn’t left his previous job, this company wouldn’t have grown.
I lef my previous job recently. We were working in two jobs for too long. And it was time to decide and to set priorities.

What about support from home?

Igor: I have support, definitely. I was already working a lot in the previous job, staying out late due to work. Now its some longer working hours, but I am thankful I have the support.  

Aleš: I have been an entrepreneur for 25 years. My family is used to me staying away from home for long hours. But yes, I can say I get full support from home.

What does a usual working day look like for you two?

Aleš:  I try to be more present here in the workshop. However, it is difficult to talk about an average job, because our work is not only related to this machine. We work and sell, we work at fairs, we work… we travel a lot.

With this new concept of offering service – infused flower that we are setting up in the Czech Republic, I will most likely be there more. But it is true that it is difficult to define a working day because there is no end to it. Because last night at 10 pm I was on a call with clients. Igor calls me at 7 am, and by then he has already sent 10 emails. We do not have a regular 8-hour working day.

Igor: I’m in the office at half past seven in the morning, depending on the situation, but basically the goal is to finish there by noon, and then go to work in the workshop. But then it depends on the situation. Sometimes something comes in between and I work later in the office or in the workshop.

What are the most common questions from potential buyers? For example the API machine.

Igor: They are interested in volume, and they are mainly interested in what kind of solvents the machine works with.

What advice would you give to future entrepreneurs who are starting out? He is similarly used to it.

Igor:  Believe in the product, whatever you are offering to the market, is definitely extremely important. And then work. Work work work. In all areas. From learning, communication. to everything.


Aleš: The bolder the idea, the greater the chances of success. What we did. this is a very bold.


Safety First: Operating Your Vacuum Impregnation Machine API 3.0

Safety First: Operating Your Vacuum Impregnation Machine API 3.0

Machinery safety guide for operating  API 3.0


This safety guide is crafted for purchasers and operators of our cutting-edge Vacuum Impregnation Machine API 3.0.
Utilizing butane as a solvent, this machine demands safety protocols due to the nature of butane. 


butane molecule


Butane is highly flammable, colorless, and odorless gas. Because of this safety at working with butane is very important. Butane can be one of the safest fuels to work with when safety practices are used.

While this guide provides critical insights, it is important to complement it with the comprehensive A.P.I. 3.0 instruction manual and adhere to state and local regulations and the ATEX directive 2014/34/EU.


Closed Loop Concept of Vacuum Impregnation Machine

A.P.I. 3.0 operates on a closed-loop concept, »loop« indicating the system’s recovery and reuse of the solvent.

The solvent initiates the cycle within a vessel, flows through another with botanical material, and ultimately returns to the original vessel, forming a continuous “loop.”

While this system minimizes environmental impact, a slight butane release during normal operation emphasizes the need for strict safety adherence to prevent any potential accidents.


Summary of Safety Requirements

Work place requirements

  • Fire extinguisher 
  • Ventilation. It is mandatory to ensure natural or mechaical ventilation. Ventilation must be done with explosion proof equipment, with regard to ensuring needed fresh air supply, placement of the inlet and outlet canales, releasing of the outlet flow in the environment. Fotka
  • All the source of potential ignition must be located outside of hazard area. That should be located outside potential explosive atmosphere, placed from the ground to prevent exposing to butane. Butane is much heavier as air so in case of the presence it will be on the bottom.
  • Butane detector alerts if there is a presence of butane gas. Butane is a colorless, and odorless gas. This makes is impossible to detect without butane detector.
    Detector must be suitable for industrial use in explosion proof protection.
    Depending on the installation the gas detector will alert about the presence of butane gas. Machine operator can then respond in time and accordingly to the safety measurements.
  • Protection against static electricity discharge. In case there is a static electricity discharge, this can cause a spark that can have sufficient energy to ignite the explosion atmosphere. To prevent static discharge all the equipment must be grounded including the flooring. Personal protection equipment like shoes and clothing should be anti.static.
  • Working place where it could come to an explosive atmosphere has to be marked with EX mark. 
Exeat API-9672 fire extinguisher
Exeat API-9638 ventilation
ex sign
exeat ventilation system

In case of a presence of butane the operator will get visual and audio alarm when Exeat ventilation system is installed. Besides that  the detector will trigger ventilator and in case of dangerous concentrations of gas all the electrical consumers will be disconeted. Leaving only ventilator work on 100%, full capcity.   

Besides that, a presence of only authorized personnel should be ensured. They should not work with open fire, smoke or use tools that overheat or generate sparks.

Flammable chemicals and cleaning agents can be in working place only during cleaning and not while potential explosion atmosphere cold occur (e.g. operating the machine). After use the chemicals and agents must be removed from the hazard area and properly stored. 

Operational requirements

Do not mix butane and air, mixing butane gas and air could lead to dangerous situation.
Prior to operating the machine, the air should be evacuated from tanks for butane gas.
And after the evacuation of air, it has to be ensured that the system is tightly sealed. Leakage test should be performed regularly.

According to the instruction manual it is mandatory to make regularly vacuum and over pressure leakage test of the system.
With vacuum and overpressure leakage test all the leaking spots can be detected.
While machine operating a leakage of the joints or seals can occur.
To minimize the possibility of leakage a totally tight systems should be ensured and tested. Besides overpressure leakage test, the accuracy of the manometers and safety valves is tested.
The leakage test will detect if the manometers and safety valves are malfunctioning (damaged or blocked).

It is prohibited to work with the equipment which is not fully functional.

Butane and other solvents

Do not use other solvent than butane or solvents that are not approved by the manufacturer.
Other solvents have different vapor pressure compared to butane. This could lead to the opening of safety pressure valves, damaging the pressure vessels or damaging the seals due to the chemical compatibility and incompatibility.


We have gathered some of the safety guides that ensure safe operation of our vacuum impregnation machine A.P.I 3.0.
As stressed at the beginning, to use our machine safely, instruction manual should be followed besides your state laws and the ATEX directive 2014/34/EU.
