Cassava starch processing machine

Cassava starch is kind of starch that is extracted from cassava roots.  Recent years,It is widely used in food and non-food industry. 

The procedures of cassava starch production are as bellow: cassava roots conveying → cleaning and washing → peeling → grinding → centrifugal sieve to remove fiber and impurities → desanding → hydrocyclone to concentrate starch and remove sundries → dewatering → drying → packaging. Vacuum dehydration is used in the starch dewatering process.

So how does vacuum dehydration work during the starch dewatering process? 
Step one of vacuum dehydration: Firstly starch slurry enters into the starch slot until it reaches the rotating drum. 
Step two of vacuum dehydration: Then starch will stick on the surface of drum by the effect of vacuum pumping and water goes into the pump. There is a layer of screen on the surface of drum to prevent starch flour going through.

Step three of vacuum dehydration: Finally the scraper on side will unload starch flour during the rotating of drum. Then starch with moisture around 38% will be sent to the next process for drying.
With advanced technology and newly design, vacuum dehydration have advantages of low energy consumption, small area, easy-operation and stable running.
The vacuum degydration is widely used in all kinds of starch dewatering process and the starch manufacturing factory.
