First, the product overview:

 

FD vacuum freeze drying is a more advanced method of dehydration of the material. The technology is to freeze the aqueous material at low temperature, and then let the water in the vacuum state directly sublimation, and condensing the method of sublimation of sublimation of water vapor, To achieve the purpose of dehydration and drying.

 

The physical, chemical and biological states of the material, which are freeze-dried by FD, are basically the same. The volatile components and the heat-denatured nutrients are very small. The dry matter is porous and its volume is basically the same as that before drying The So after the water due to contact area, can be quickly restored in the sealed container has a longer shelf life.

 

FD vacuum freeze dryer is widely used in a variety of heat-sensitive biological products development and production. Such as vaccines, vaccines, drugs, vegetables, vacuum packaging, snake powder, fish turtle capsules and so on.

 

With the development of biomedical health and food and health care products industry, vacuum freeze dryer has become a necessary equipment for pharmaceutical, food and health care industry and scientific research units.

 

Second, the product features:

 

Dry vacuum freeze dryer is aimed at the existing conventional vacuum drying and oven, to upgrade the design and transformation, and truly master the core technology of new products. It is the use of vacuum drying principle, compact and reasonable structure, easy maintenance, automatic control, easy to operate; in the same material heating temperature, compared with the conventional vacuum drying and oven:

 

1. With the drying speed, time shortened 3 to 10 times;

 

2. Low energy consumption, only ordinary dryer energy consumption of 20% -30%;

 

3. Drying temperature range (-55 ℃ ~ 120 ℃ can be dry), in the low temperature range (-20 ℃ ~ 50 ℃) for rapid drying;

 

4. Drying chamber in the vacuum anaerobic, dry quality and the quality of fresh raw materials can be adjacent to the United States;

 

5. It can be organic solvent recovery, is conducive to reducing production costs and environmental protection, especially for ordinary dryers can not dry organic solvent-containing materials.

 

6. Vertical open door structure, can be achieved in situ freeze-dried materials;

 

7. Control system to PLC as the core, the use of touch screen as a man-machine interface, real-time record of freeze-drying process in the multi-channel temperature data, and the curve can be viewed, man-machine interface clear and intuitive.

 

8. Preset shelf temperature control curve, to achieve the sublimation process automation.

 

9. Host with a USB interface, the freeze-dried data can be uploaded to the computer in real time and save, browse, print and other functions.

 

Third, the scope of application:

 

Food industry: vacuum freeze-drying technology can be used for fruits and vegetables, meat and poultry, aquatic products, condiments, convenience foods and famous specialty and other dry, can be achieved to maintain the original food color, smell, taste, shape, freshness unchanged, Good water quality, easy to store and transport products, lower costs, longer shelf life.

 

Nutrition and health care: in the dry royal jelly, ginseng, turtle, turtle, earthworms and other nutritional health products, the use of vacuum freeze drying process, but also make people believe that the nutrition is pure and natural.

 

Pharmaceutical industry: Vacuum freeze-drying method can be used in serum, plasma, vaccines, enzymes, antibiotics, hormones and other Chinese and Western medicine dehydration and preservation. Biological research: the use of vacuum freeze-drying technology long-term preservation of blood, bacteria, arteries, bones, skin, cornea, nerve tissue and various organs, in use only need to supply water can be regenerated, still maintain its biological characteristics.

 

Other: such as in the production of aerospace insulation ceramics, archaeological wood products preservation, specimen production, special materials, such as the application, can receive a unique effect.
