What Is The Process of Starch Produtcion Line ?

2017-02-10

The starch grains contained in the cassava cells are extracted by crushing the tubers, which releases them from the destroyed cells. The resulted starch is then washed out, dried to powder, and ready to use in either food or various technical applications. What’s the function of cassava starch production equipment?
 
The handling of the cassava starch production line in this stage is a complex process, since it has to be dewatered without using high temperatures, in order to avoid gelatinisation – the destruction of its granular structure. The general technological process of CASSAVA STARCH PRODUCTION EQUIPMENT.
 
Cassava starch production equipment dewatering is usually a two-stage process: first the excess water is removed using a rotating vacuum filter, followed by further drying the starch without pasting it, by using a pneumatic dryer. Vacuum pump enables to form the negative pressure inside of the vacuum drum; when starch milk contacts vacuum drum, starch milk is sucked on the drum surface; filtrate is drawn to the filtrate separation tank and is pumped away by the filtrate pump; filter cake is scraped by a scraper and conveyed into the feeding hopper of flash dryer by food-grade conveyor belt.
 
High temperatures may be used in this last stage of cassava starch production equipment, at the end of which starch loses the final percentage of water, to achieve 20% moisture.
