Vaccum freezing drying machine is an advanced Hi-Tech dehydration technology, freeze dried raspberries machine/freeze dryer makes hydrous materials frozen in the low temperature status, then under the vacuum condition, Shandong Leader Machinery Co.,ltd. adopts thermal radiation method for heating, to sublimate ice to gas directly. After the moisture comes out, Vaccum freezing drying machine uses ice-condenser (cold trap) and vacuum device to dehydrate the water content. freeze dried raspberries machine/freeze dryer 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.). Vaccum freezing drying machine Suitable for food lyophilization processing in the area of vegetables and fruits, dietary supplements, instant food, condiments, biological product, medicine, beverage and etc. Shandong Leader Machinery Co.,ltd. Lyophilization is a dehydration method that Vaccum freezing drying machine to sublime the material containing water from frozen solid state to steam state directly under the vacuum and low temperature condition.Vaccum freezing drying machine 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 freeze dried raspberries machine/freeze dryer has basically unchanged volume and shape with spongy appearance.
Freeze dried raspberries machine/freeze dryerProduct Description
Our company specializes in food vacuum freeze-drying technology development and equipment design, manufacture, installation, commissioning of the high-tech enterprises. Mechanical technology involved food freeze dryer, vacuum, refrigeration, thermal, electronic, automatic control theory and in practice has a wealth of experience.
Advantage of vacuum freeze drying machine:
Comparing with traditional hot air dehydrated products, the Freeze Dry products have unique characters and advantages. The most clear difference is the appearance of the final products, this products will keep the same shape and color as they were frozen, it won't become shrink or darken after drying. Further inside quality of the products, due to low temperature drying technology, the nutritons within the products have been preserved at the highest level. And due to the sublimation process had minimum damage for the material structure and cellular tissues, the rehydration rate is extremely high. After the rehydration, the products will be with very close charaters with the fresh materials. And many other advantages due to the low moisture content after freeze drying. The products can be stored for a very long period. Comparing with frozen products, it is much easier and cost efficient for transportation and storage. ( freeze dried rose petals machine )
Working principle of vacuum freeze drying machine:
Instead of traditional vaporization dehydration method, the vacuum freeze drying technology is dehydrate products by sublimation directly from ice to vapor. During the Freeze drying process, the materials will be frozen to -18°c, then move into the vacuum drying tank for dehydration, automatic control system will set the vacuum and heating temperature according to the freeze drying cirve of each products to maintain the proper circumstances for processing. The materials stay in frozen status during the drying process and water vapor will be condensed on the surface of cold trap coils to absort the water out from the materials.
