Performance characteristics and application range of rotary vacuum rake dryer
- Oct 19, 2018 -

The rotary vacuum rake dryer is used to achieve the automatic constant temperature control during the drying process. It can be used to dry biochemical products and mineral raw materials at temperatures between 20 and 160 °C. In the drying process, the thermal efficiency is higher, which is more than 2 times higher than that of a general oven. Moreover, indirect heating is used, so that the material can be prevented from being contaminated.


In daily use, the operation, maintenance and maintenance of the rotary vacuum rake dryer are very simple and easy to clean. Since it is operated under vacuum conditions, the boiling point of the material solution is lowered, and the heat transfer driving force of the evaporator is increased, so that the heat transfer area of the evaporator can be saved for a certain amount of heat transfer. The heat source for the evaporation operation may use low pressure steam or waste heat steam, and the heat loss of the evaporator is small.


Due to these advantages, the rotary vacuum rake dryer can be used to dry many different materials, such as the following materials in the pharmaceutical, food, chemical and other industries: slurry, paste, powder materials; Heat-sensitive materials; easy to oxidize, explosive, strong irritant, highly toxic materials; materials requiring recovery of organic solvents.http://www.syhgzben.com/
