One. Ethanol Extraction

Using ethanol extraction involves heating the cannabis plant material to "decarboxylate (or remove carbon atoms from the carbon chain) and then soaking the plant material in ethanol for a period of time.

Since it can be done at home, no specific expertise is required.

Bay Carbon dioxide extraction

CO2 extraction requires specialized equipment to cool the CO2 to below -69°F and 75 psi, creating a supercritical state. After that, a room filled with hemp plant material is filled with this CO2, trichomes and terpenes are dissolved in the CO2 - then the CO2 passes through a separator and the CBD oil is left behind.

There are no specific specialty requirements, but specialized equipment is necessary.

C. Butane/propane Extraction

Butane/propane extraction is commonly referred to as solvent extraction and may involve the use of ethanol, butane, propane, isopropanol or alcohol to extract CBD. it is considered one of the cheapest options and one of the fastest extraction methods.

It can be done at home by adding the liquid to the plant. No expertise is required.

d. Ice water extraction

Ice water extraction produces a powdered resin extract, often called hashish. First, chopped plant excipients are mixed with ice or dry ice.

Next, water is added to the mixture and then filtered through a mesh bag. Finally, excess water is drained and the extract is allowed to dry.

It can be done at home and does not require expertise.

e. Water Vapor Extraction

Water vapor extraction is done entirely by a machine that vaporizes or burns the cannabis material. The heating element first intentionally targets the vaporization point of the cannabis, thus producing different combinations of cannabinoids that can be used in the development of the product.

Next, the vapor is processed to "recapture the activated cannabis molecules, which are then passed to the dissolution unit where it is dissolved into a liquid and stored for further processing."

This method requires specialized machines, but requires specific knowledge of how to operate them.

3) After a processing run with the machine, what filtration process is needed to further purify the CBD?

Once again, it depends on the CBD extraction method.

One. Ethanol extraction

None.

Bay Carbon Dioxide Extraction

None.

C. Butane/propane extraction

Overwintering is the process of removing unwanted elements from the plant, such as fats, waxes and lipids, and is only needed when extracting oil at high pressure/high temperature (supercritical), as this intense extraction will extract everything from the plant, including materials you don't want in the final product. The extracted oil is called crude oil and needs to be filtered to become fine.

d. Ice Water Extraction

None.

e. Water Vapor Extraction

None.

4) What is the final purity of CBD after extraction?

Ethanol extraction: 99%

Carbon Dioxide Extraction: 98%

Butane/propane extraction: 95%

Ice water extraction: 97%

Water vapor extraction rate: 97%

5) Does the machine require additional components to expand or scale up operation?

One type. Ethanol extraction

None.

Bay Carbon Dioxide Extraction

Different systems are available for different sizes of operations. Larger systems are required for scale-up operations.

The Hi-Flo FX2 Series is a commercial supercritical extractor capable of handling up to 107 lbs. of biomass per day.

C. Butane/propane extraction

None.

d. Ice Water Extraction

Yes. Eberbach Model E5703 can be further filled with Mountain High suction cups.

e. Water Vapor Extraction

None.

6) What are the safety considerations for CBD extraction equipment?

Ethanol extraction: None, the entire process is done inside the machine, no specific requirements.

CO2 extraction and butane/propane extraction: depends on the country/region. In the US, safety equipment and special facilities are required by law to handle flammable solvents.

Ice water extraction n: None.

Water vapor extraction: Specialized facilities for conditioning water vapor.

7) What warranty (if any) is included with the purchase of the equipment?

Precision Extraction Tools Offers a warranty that is included in the price.

Pilotech offers a warranty for an additional price.

Right Stuff Equipment does not offer a warranty, nor does Cannabis Oil Tech or Mixers.

8) Does the manufacturer provide training?

Mechanical training is required for two methods.

Carbon Dioxide Extraction

butane extraction.

The following are some of the manufacturers we have found that offer training for purchase.

Precision Extraction Tools.

SC botanicals, the

Right Stuff Equipment, and

Cannabis Oil Technology

9) How much monitoring is required to run a machine?

Ethanol Extraction: After ethanol extraction, depending on the product - sometimes additional purification is required. Personnel need to check the equipment and transfer the product to another machine.

The machines used for ethanol extraction are the X10 MSE (Multi-Solvent Extractor) and the PX1 Hydrocarbon Extractor.

CO2 extraction: The XMOD MSE is an unsupervised machine because it allows "uninterrupted extraction operations".

Butane/propane extraction: PX1 Hydrocarbon and PX2 Hydrocarbon are examples of machines that handle butane/propane extraction. These machines require supervision, but do not require continuous monitoring.

Ice Water Extraction: Due to the need for continuous supervision, Eden Labs recommends that water extractions be performed in their lab.

Water Vapor Extraction: Due to the need for ongoing supervision, Eden Labs recommends that water extraction be performed in their lab.

10) Does the machine require frequent hemp feeding?

The machines have three automation settings, manual, semi-automatic and fully automatic.

Manual, semi-automatic and automatic machines are all based primarily on whether the final extraction process is manual or not.

Depending on the manufacturer and different industry guidelines, three types of machines are available for each extraction method, depending on the size of the operation. For small operations, manual machines are recommended, which will involve a completely manual extraction process.

Semi-automatic machines require the use of manual valves and require more frequent loading and unloading of the machine.

Automatic machines do all the work themselves, including extracting and loading the material.

It also depends on how much cannabis you want to process per day.

Machines can process up to 100 pounds of cannabis per day. However, the most efficient extraction that can achieve this speed is CO2 extraction.

11) Do you need to worry about solvent handling?

Since CO2 and water are natural solvents, they do not need to be disposed of and only need to be recycled for future use.

Solvents such as butane, propane, hexane, isopropanol and ethanol used in the solid extraction process can also be recycled. A machine that offers this capability is Maratek's Solvent Save Batch (SSB) solvent recovery and recycling equipment.

The cost of recycling is equal to the cost of obtaining a recycling or recovery machine.
