Product Description

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.

Product Application

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.

Product Feature

1

It drys at low temperature in order to make protein degeneration, micro-organisms loss biological activity.
2

The material in the volatile components and nutrients heated degeneration of and aromatic ingredients loss a little because of the low-temperature drying.
3

It is almost impossible for microorganisms and the role to grow so that the material can maintain the original character in the low-temperature drying process.
4

The volume and shape essentially doesn’t change and has a strong water uptake after drying.
5

Because it has little oxygen under the vacuum drying, the vulnerable materials have been protected.
6

It can remove 95-99.5 percent of water, and the retention period lasts longer.
