Supercritical CO2 extraction
Supercritical CO2 extraction equipment because it produces a cleaner, purer extract. It leaves no traces as do other solvents such as propane and butane or alcohol/ethanol mixtures. This is very important, especially in pharmaceutical products. Carbon dioxide is a versatile solvent used in a wide variety of industrial processes. It is also sustainable in closed-loop extractors, where carbon dioxide is recycled back into the storage tank at the end of each extraction operation, also known as carbon dioxide critical extraction.
Supercritical CO2 extraction equipment can extract terpenes (odours). A good number of customers routinely run terpenes, harvest the extract, continue with a subcritical run (low pressure, low temperature), harvest the extract, and, finally, complete a supercritical run (high pressure, high temperature). This way, they can take everything out of the plant. Each extract is treated differently. Terpene extracts can go straight to the oil pen because the oil is light, aromatic, and pure. Oils from plant materials that contain more supercritical components require post-treatment to remove the fats, waxes and lipids that are extracted with the oil.
Diaphragm Compressor Technology: The Science Behind High Quality, High Yield
Our systems use diaphragm compressor technology, which utilises a cold separation process driven by energy-efficient air pumps. Cold separation means that the separation vessel can be kept at a lower (cold) temperature to preserve the terpenes in the vegetable oils, resulting in higher quality and higher quantity extractions.
There are significant differences between liquid and gas pumps. Since liquids are 10 times denser than gases, liquids are an easier mechanism to pump; however, liquid pumping actually consumes more energy throughout the extraction process. As is common in this industry, there are widespread calls for increased output from liquid pumping, but proponents ignore the increased energy consumption and higher temperatures that lead to thermal degradation.
In order to extract vegetable oils, liquid carbon dioxide has to be converted to a gaseous state. The phase change requires significant heating and cooling. This is why diaphragm compressor technology with regenerative heat exchange in the extraction system is designed to capture the hot and cold air that cancels each other out. This eliminates the need for additional heaters/coolers and typically consumes 33 per cent less energy than other manufacturers' extraction equipment.

Make Your Research More Accurate & Efficient
We design and manufacture extraction prodcution line for users in need of a simple device for small amounts of extract, as well as more complex equipment for industrial use. Our offer includes preprocess(dryer /grinder) ,coating machine ,package machine and process systems where the substance used as solvent is either a volatile hydrocarbon (butane extraction), an alcohol (alcohol extraction), or CO2 (supercritical extraction). Given the investment cost, complexity of use, and extract quality, each system has some advantages and disadvantages.
