FAQ

• Do I need GMP machine?
• If your plan is to supply the pharmaceutical or cosmetic industry, then YES, you need GMP machine.
• Is your machine food standard grade?
• Yes, our machine design follows the HACCP guideline.
• Do I need a very high flow CO2 pump?
• Industrially, lower pump flow is always the best choice, as the CO2 solvent remains for a longer time in contact with the raw material. Very fast flow can result in a lower yield of extraction and lower efficiency.
• Is cleaning important?
• The cleaning is more than important! Polluted extract will not be accepted by your customers. Cleaning procedure is as important as extraction procedure. If the system doesn’t allow a good cleaning, than that machine is not the right choice for you.
• What size equipment do you offer?
• We can supply you with 0.5L~4500L machines. The pressure is from 30MPa-60MPa.
• Can carbon dioxide be reused?
• The CO2 gas is recycled during the extraction process.
• After the extraction is completed, if the system is equipped with a CO2 recovery unit, we can recover 30% of the CO2 gas.
• We do not recommend configuring a CO2 recovery system in a 0.5L-10L unit.
• How long does it take to deliver when I complete my order?
• The 0.5L-150L supercritical extraction equipment takes about 60 working days.Equipment above 200L takes approximately 90 business days.We are responsible for the quality of our customers' machines and must strictly check each procedure and details.
• How will my order be packed, can you provide the installation service?
• Plywood case and wooden case. And we will assemble and test the machine before packing. If customer need, we will send one engineer for assembling and training for workers. Also welcome factory visit, please contact [email protected]
• Quality guarantee?
• One year after shipment excluding the wearing and tearing parts.
• Installation?
• We will assemble and test the machine before packing. Also send English manual. If customer need, we will send one engineer for assembling and training of workers. Per person per day cost, food,accommodation and air-ticket will be on clients.
• What does You need from me to quote a price?
• a).Raw material b).Production capacity per batch, we supply 0.5L~4500L machine for you, big capacity of machine can be customized according to your request for your request.
• What material can you process with this machine?
• Our CO2 extract machine is widely used in extracting hemp oil, wheat embryo oil, fish oil, tobacco essential oil, Arteannuin, Sundrops oil, Gingerol, Pepper haematochrome, Hops extract, Agarwood oil etc.
• What is the machine material you use?
• Stainless steel.
• What is the highest pressure does your machine can suffer?
• 60Mpa. Our standard design is 40Mpa.
• Does the CO2 can be reused?
• CO2 can be used in circulation.
• Can we do extraction test before purchasing?
• Of course, we can do extraction test with your raw material and send you videos and pictures FYI.
• Do you have machine in stock?
• No, every machine is customized according to your order.
• Is supercritical CO2 a new solvent ?
• No, it has been used for several years in numerous extraction industrial processes: in coffee decaffeination, in cork treatment to remove cork taint, in sesame oil production, and also in medical domains, to impregnate implants or sterilize instruments.
• Why use Supercritical CO2?
• CO2 by itself is not a strong solvent, but, by putting it under pressure and adding some heat, it extracts an incredibly rich, concentrated and toxin free product. This makes for a safer work environment and a healthier end product. Many of the companies we work with in the flavoring and nutraceuticals industry tout the fact that their product is produced with Supercritical CO2 extraction as an effective marketing tool. Consumers are becoming more conscious of how products are prepared and what is in them.
• What will the yield be using Supercritical Fluid Extraction (SFE)?
• This depends on the material being extracted and the protocols being used. Generally, CO2 is used to extract oil, so the more resinous your material is, the better your yields will be. We have experience with a wide variety of botanicals and the parameters needed to get the best results.
• What kind of routine maintenance do supercritical systems require?
• Our systems can run continuously with little maintenance. The materials which run through the vessel are soluble, so almost no cleaning is required. For example, when using the system to extract new materials, the only maintenance required is to run the system while it is empty in order to clean it out. If you need to be certain there are no residuals, you flush the system with ethanol. Minimal maintenance required consists of cleaning the filter behind the pump, testing the relief valves, monitoring compressor oil levels, and occasionally replacing gaskets and O-rings. To keep you and your business consistently running, routine maintenance will be taught during your training.
• What’s the ideal environment to operate the system?
• Maximum environmental temperature should be about 22°C / 72°F. Humidity should be in the range of 30%-60%. You will want 10 - 15 air exchanges per hour or as required by regulation. For ventilation, you will want enough to sufficiently remove gases released from vent points on the Hi-Flo system.
• How should I prep the plant material?
• As dry as possible, a fine grind, with a light pack is best used in the extraction vessel.
• Is a CO2 System environmentally friendly? CO2 as a solvent is inert, non-toxic, and non-flammable. It’s also notable that CO2 as a solvent is far more environmentally friendly than other solvents which are derived from petroleum products.
• Is CO2 considered Generally Recognized As Safe (GRAS)? The United States Food and Drug Administration declare that extraction processes which use CO2 as a safe method for food, and is compliant with good manufacturing practices (GMP). CO2 alone is so inert that it does not even have classific
• What is Hemp Extract? Exactly what is CBD Oil?
• Premium Hemp Extract is a naturally taking place constituent of commercial hemp/cannabis. Its formula is C21H30O2 and it has a molecular mass of 314.4636. It is the most abundant non-psychoactive cannabinoid found in marijuana, and is being scientifically investigated for numerous reasons. Hemp oil is a marijuana oil (whether derived from cannabis or industrial hemp, as the word marijuana is the latin genus name for both) that has significant amounts of Hemp Extract included within it. Our Premium Hemp Extract items and extracts are stemmed from commercial hemp, so they could be considered hemp oil, hemp obtained Hemp oil, Hemp-rich cannabis oil, or plainly “hemp extracts” because they generally contain much more than just Hemp Extract Once again, cannabis doesn't suggest marijuana, however is the genus name, and general umbrella term which all types of cannabis and hemp fall under.
