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. Our goal has always been finding new user friendly solutions, which is why extraction equipment development is one of our top priorities.

Extraction – CBD and other cannabidiol substances are extracted from dried hemp. What is produced at this process is a solution composed of crude oil extract and solvent-ethanol.
Filtration – Remove the vegetable oil glycerides and cellulose that are insoluble in ethanol and achieve the goal of dewaxing.
Evaporation – Remove and recover most of the ethanol to obtain an extract with only a small amount of ethanol remaining.
Decarboxylation – Convert CBD-A into CBD, remove light components (such as some aromatic hydrocarbons and hydrocarbon light terpenes), residual ethanol and water will also be removed in this process.
Distillation – An important section of the CBD process, 96%+ purity cbd oil can be obtained.
Crystallization – 99% pure CBD crystals can be achieved.
Drying– Dry CBD crystals at low temperature in a vacuum drying oven to remove residual solvents, protect CBD from excessive heat when removing residual pentane.
