LTDG-20S Pilot Freeze Dryer

Freeze dryer is widely applied in pharmaceutical industry, biotechnology industry , biological science industry, materials science industry, chemical industry, food and agriculture industry etc. it is used to produce vaccines, drugs and permanently store biological tissues/organs.

Pilot freeze dryer is a small in-situ freeze-drying equipment. It is applied not only in pharmaceutical pilot workshop and small batch production but also in food or medicinal freeze-dry-ing process. Situ freeze-drying technology is one of advanced international constructer design which avoid the contamination during materials transfer and realize the dry sublimation automatically.Pilot freeze dryer is with rack heating programmable function and memory freeze-drying curve which convenient users to get the freeze-drying production technology.

lt is divided into standard type and gland type.

The pilot lyophilizer is widely used in bio pharmaceutical, medical, food and other industries.

1. Pharmaceutical industry: It is used for dehydration and preservation of Chinese and Western medicines such as serum, plasma, vaccines, enzymes, antibiotics, hormones, etc.

2. Food industry: vacuum freeze-drying technology is mainly used in the food industry to dry coffee, vegetables, fruits, strawberries, meat, etc., which can keep the color, flavor, taste, shape and nutritional components of food unchanged, and facilitate long-term storage and transportation.

3. Nutrition and health care: The vacuum freeze-drying technology can also be used to dry royal jelly, pearl powder, ginseng, turtle powder, black ant powder, snake powder, etc. It can preserve its nutritional ingredients and active ingredients for a long time.
