Dryer machine
HFD series Vacuum Freeze dryer machine
Product description
HFD series machine is applicable to the bacteria, virus, plasma, serum extract, antibody, vaccine and drug products: such as chloramphenicol, streptomycin, vitamins, enzymes and biological test of the plant extracts.
The principle of sublimation can be explained briefly with water map. When the pressure is higher than 611Pa, the water will go through three phases of solid, liquid and gas. When the air pressure is equal to 611Pa, the dissolution curve, the vapor pressure curve and the sublimation curve three lines are at one point, that is, the three phase point. When the pressure is lower than 611Pa and reached the sublimation curve, the ice can be directly into a solid state gas.
There are five hot sales model, HFD-1 HFD-4 HFD -6 HFD-8 HFD-15, the major difference is the capacity higher increase.
