The freeze drying technology is the most advanced food dehydration processing technology at present. The freeze-dried food processed by this technology has long expiration date, good reconstitution property, color, aroma, taste and nutrition. The volume and shape of the food is essentially constant, showing a spongy state without drying shrinkage phenomenon. It can be used in vegetables, fruits, condiments, aquatic products, biological products, medicines, beverages, specimens, and other fields.
1. Continuous feed-in, dry, granulate, discharge in vacuum state.
2. Less labor cost and energy consumption.
3. Excellent quality of the products.
4. Completely closed system, simplified processes and no contamination.
5. Little loss of product and solvent recycling possible.
6. Adjustable drying temperature & drying time.
7. PLC automatic control system & CIP cleaning system.
The dryer for liquid& paste is mainly used in drying many kinds of liquid or paste raw material, such as traditional & western medicines, food, biological products, chemical material, health foods, food additive etc, especially suitable for drying material with high-viscosity, easy agglomeration, or thermoplastic, thermal sensitivity, or material that can not be dried by traditional dryer.
For above materials, Vacuum belt dryer is the best choice:
Pharmaceutical industry: Chinese medicine extract, plant extract, egg embryo, PVPK series, fermenting liquid etc
Food industry: malt extract, carbohydrate, instant beverage, tea powder, cocoa powder, corn paste etc Chemical Industry: lithium battery, etc.
This equipment is a vacuum chamber where a material conveying guide belt(Teflon PTFE) is fixed in it. Materials are distributed continuously on the guide belt after they pass through the vacuum continuous distributor on the top of the equipment. Based on material properties, the material distribution thickness is adjustable. The guide belt keeps conveying slowly to the other end, with the heating zone under it to provide drying heat for the belt, so the materials on the belt evaporate water during convoying constantly and the vapor is quickly removed by vacuum.
1.Short drying time (adjustable between 30-90 minutes)
2.Minimum loss of aroma
3.High yield of final products(99%)
4.No Oxidation of product
5.Solvent recycling possible
6.Less energy consumption
7.Completely closed system
9.Good instant properties of the drier products
