Product Description
Lyophilization or freeze drying is a process in which water is frozen, followed by its removal from the sample, initially by sublimation (primary drying) and then by desorption (secondary drying). Freezedrying is a process of drying in which water is
sublimed from the product after it is frozen. It is a drying process applicable to manufacture of certain pharmaceuticals and biologicals that are thermolabile or otherwise unstable in aqueous solutions for prolonged storage periods, but that are stable in the dry state.

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.
