Vacuum freezing dryer in extracting polysaccharide freeze-dried matters needing attention

Vacuum freezing dryer in extracting polysaccharide freeze-dried considerations, vacuum freeze drying plant home as you summarized below:
1, dry polysaccharide can not directly, can affect the structure of product with crystal;
2, high viscosity and concentration of sugar, mostly freeze-dried longer;
3, polysaccharide easy absorption of moisture, dry vacuum freezing dryer using the environment,
4, polysaccharide, freeze drying, need frozen well in advance, The first sugar liquid frozen into ice) And then to dry faster;
