Freeze-drying (freeze-drying for short) is a stable process of drying materials. It first freezes the water-containing materials into solids, and then sublimates the water from the solids to the air, and removes the water to preserve the products in the solution phase through sublimation and desorption.
After freezing, the solvent is reduced to a certain extent, thereby preventing the formation of microorganisms or the chemical reaction between the solute and the solvent, so that the product can be stored for a long time and its properties can be maintained.
1Stainless steel is polished with excellent brand to ensure surface roughness to ensure sterility requirements
2.Cabinet, board level,and hose are tested after multiple procedures to ensure without leakage
3.Screw compressor is used Blitzer refrigeration compressor, more stable performance, reliable, easy to maintain
4.Temperature and pressure of compressor has multiple protection features
5.Suction filter settings, prevent degeneration of stolen goods and acid materials into the compressor chamber , corrosion internal parts and refrigeration oil.
6.Exhaust temperature protection set to avoid oil degeneration in extreme conditions , to reduce the exhaust temperature by cooling motor
7.Compliance with the Montreal Convention, with environmentally friendly refrigerants;
