Product Application

Vacuum Freeze Dryer is an advanced Hi-Tech dehydration technology, It makes hydrous materials frozen in the low temperature status, then under the vacuum condition, it adopts thermal radiation method for heating, to sublimate ice to gas directly. After the moisture comes out, it uses ice-condenser (cold trap) and vacuum device to dehydrate the water content. It is a combined application technology based on multidisciplinary development, including refrigeration, heating, vacuum, biological, electrical and etc. Vacuum freeze drying technology has widely application, such as for chemical products, biologics, health product, herbs, agricultural products ( meat, poulty, egg, sea food, vegetables and fruits and etc.)

Main Features

1) Suitable for food lyophilization processing in the area of vegetables and fruits, dietary supplements, instant food, condiments, biological product, medicine, beverage and etc.
2) Lyophilization is a dehydration method that to sublime the material containing water from frozen solid state to steam state directly under the vacuum and low temperature condition.
3) It’s the most advanced dehydration technic in the world currently with the advantages of long period quality assurance, good-rehydration, good condition of the looking, flavor, taste and high content nutritious remains. The finished product has basically unchanged volume and shape with spongy appearance.
4) Easy storage and transportation.
5) High automatic control with time and temperature adjustable operation.
6) Adopt the water-sealed pump and oil-sealed pump vacuum system, closed circulation heating system, postposition and bottom-position cold trap to make sure the efficient operation with equal quality.
7) Extraordinary freezing efficiency is guaranteed by the extremely efficient evaporator, optimized design and quality finishing.
