Waxberry Freeze Dryer (ZG-20)

WAXBERRY FREEZE DRYER

Waxberry freeze dryer is also called lyophilizer. Waxberry freeze dryer is the equipment for dehydration. Originated in the 19th century, waxberry freeze dryer made considerable progress in the last 20 years. Nowadays waxberry freeze dryer is widely used in medicine, biological products, food, blood products, active substances field.

Working principle of waxberry freeze dryer:
Under vacuum condition, material is freeze dried via principle of sublimation. The moisture in the pre-frozen material is directly sublimed from solid state (ice) to gaseous state (vapor), without melting. Freeze dried products is formed as sponginess, no shrinkage, rehydration excellent, very little water containing. The appropriate packaging can be stored and transported at room temperature for a long time.

Advantage of waxberry freeze dryer:
There are variety of drying methods, such as sunshine bask drying, boiled drying, parch drying, spray drying and vacuum drying. But the ordinary drying methods are usually above 0 ° C or higher temperatures, so the dried products are small in size, texture harden, and some heat-sensitive material nature changed, inactivation, and some substances even oxidation. But our waxberry freeze dryer worked below 0 ° C, so the freeze dried products can keep its original color, smell, taste, shape, bioactive molecule and prevents the lost of nutrition, and also easily regain water.

Features of waxberry freeze dryer:
1, heat-sensitive material will not inactivation
2, the loss of volatile components of the material is very small
3, freeze dried material can maintain its original character
4, waxberry freeze dryer working in the frozen state, so the volume is almost unchanged, maintaining the original structure
5, the dried material porous, spongy, add water, dissolve quickly and completely, and almost immediately to restore the original traits
6, due to drying under vacuum, very little oxygen, and therefore are easily oxidized substances have been protected
7, waxberry freeze dryer can remove more than 95% to 99% moisture, the dried product can be stored for a long period without deterioration
8, low assembling power, save cost and energy.

Waxberry freeze dryer needs to be worked in low temperature and vacuum condition, so refrigeration system and vacuum system must be adopted on waxberry freeze dryer. High quality Germany Bitzer or Italy Refcomp refrigerator and Germany Leybold or England Edwards vacuum pump, and also Siemens control systems are configured in our waxberry freeze dryer system to ensure stable performance.
