Drying process during cassava flour processing

Cassava flour processing plant now own a bright market because cassava flour could be as a replacement for starch. Nowadays cassava flour processing industry become more and more popular in all the world. To get high quality cassava flour, the cassava flour drying process is very important, here we introduce our processing technology about drying process during cassava flour processing.   

Cassava flour dewatering machine

Cassava flour dewatering process:

Because there is hydrocyanic acid toxic substance in cassava peels. In this unit, we use filter presser to dewatering and detoxification process.

When slurry reaches to certain liquid position in slurry tank, start to dewater by filter presser. Then transport the material to cassava flour drying procedure by belt conveyor.

Cassava flour drying process:

Dewatered cassava flour cake contains high moisture to 45~50%, which can’t enter into flash dryer directly and will be mixed with dry flour and reduce the moisture to 38%, then transported to feeding port of flash dryer by conveyer belt, pass through feeder and enter into raiser. The heat source of flash dryer is steam heat exchanger. Wet cassava flour is heated by hot wind and water is steamed. After drying, cassava flour and air are separated in cyclone separator. At the bottom of cyclone separator, it is closed by air closer. after wet air leave cyclone separator , which is discharged in to atmosphere. Collected cassava flour is transported to vibration sieve unit; the coarse particulate matter is sieved out. The sieved cassava flour is transported to hopper for storing and cooling.
