The vacuum freeze drying machine is an advanced method for the material for the material de-watering. It freezes the moisture material in the low temperature and makes the water inside sublimate directly in the vacuum condition. Then it collects the sublimated vapor by means of the condensing way so as to dewater and dry the material. Being processed by the vacuum freeze drying, the physical, chemical and biological states of the material are basically unchanged. The volatile and nutritious contents in the material, which are easy to be denatured in a warm condition, will be lost a little. When the material is freezing dried, it will be formed into a porous one and its volume be basically the same to that before drying. Therefore, the processed material can be recovered quickly if being watered again, because of its large contacting area and it can be stored for a long period in a sealed vessel.

Character
1.The drying speed is fast and the time is shortened by 3 times 10 times.
2. Low energy consumption, only 20% to 30% of the energy consumption of ordinary dryers
3.Because freeze-drying is carried out at low temperature, it is especially suitable for many thermosensitive substances. Proteins, microbes, etc., do not mutate or lose biological activity, and oxidizing substances are fully protected.
4.The volume is almost the same, the original structure is maintained, there will be no concentration, and the loss of some volatile components in the substance is very small.
5.It can discharge more than 95% of the water, and the product can be preserved for a long time without adding any preservatives.
6.The dried material is loose and porous, spongy, dissolves quickly and completely after adding water, and returns to its original character almost immediately.
7. The drying temperature range is wide (- 55 ℃ ~ 120 ℃ can be dried), and the rapid drying can be carried out in the low temperature range (- 20 ℃ ~ 50 ℃).
8. It can recover organic solvents, which is beneficial to reduce production cost and environmental protection.
9. Vertical open door structure, which can realize in situ freeze-drying of materials.
