  Vacuum Belt Dryer

1)  What is vacuum belt dryer?

Vacuum belt / band driers consist of a housing with built-in conveyer belts for the product running over heating plates. Automatic belt control ensures precision belt operation. The belts run parallel to one another and a metering pump with oscillating application nozzle is assigned to each individually controlled belt.

2) How does vacuum belt dryer work?

The shift in the boiling point under vacuum provides for a low evaporation temperature and therefore gentle product temperature. 

Pumpable products usually run through a highly viscous, frequently sticky phase during the drying process. This formation of vapor bubbles in the product results in a dry cake on the belt toward the end of the drying process. The temperature to which the product is subjected during the drying process has a significant effect on the achievable product quality. The belts run over a number of heating zones and over a cooling zone at the end. Steam, pressurized water or thermal oil can be used for heating; each zone can be controlled separately, allowing the temperature of the heating surfaces to be adapted to the specific requirements of the product.

The entire vacuum belt / band drying system is controlled by a stored program control (SPC) and operated over a control panel or PC. All parameters and errors are logged. Recipe mode, hand-over protocol, supervisor, server link, and operating and maintenance instructions via PC are possible.

The dry cake is cooled to a brittle breakage consistency in the final zone, then chopped up with a guillotine and crushed up in a breaker or granulator.

3)   What is the use of vacuum belt dryer?

(1)   Vacuum belt dryer for liquid and paste:

Vacuum belt dryer (VBD) is used to dry many kinds of raw materials in liquid or paste, such as Traditional & Western medicines, food, biological products, chemical material, health foods, food additive etc., for example, malt extract, instant coffee, instant Milk products, cocoa powder, Chinese medicine extract, plant extract, egg embryo, PVPK series and various Corn steep liquor, etc. Especially suitable for drying material with high-viscosity, easy for agglomeration, or thermoplastic, thermal sensitivity, or material can not be dried or not suitable by spray dryer. For these materials, VBD is the best choice.
