Potato starch is a kind of white powder of tapioca that is dehydrated and dried after starch extraction, which is widely used in food industry and non-food industry. Potato starch processing is a very promising market that many people want to invest it,but they have the doubts about how to process potato starch?Here I am so glad to share the potato starch production process with you:

Potato starch production process

①Potato starch processing technology order is:

Fresh potato - Potato cleaning section- Potato grinding section- Potato starch extracting section - Starch concentrating section - wet starch dewatering section - potato starch drying section

②Main equipment used in potato starch processing:

Dry sieve - rotary washing machine -rasper- centrifuge sieve- Hydrocyclone station- vacuum filter - Flash Dryer

③Detailed Potato starch production process:

A. Cleaning section:to remove the impurities attached to potato

First of all, use dry sieve and rotary washing machine to remove impurities firstly, like small size dirty, sand and stones, or any other small size dirties which is attached to the potato surface.

B.Grinding section: to grind potato into slurry

After cleaning, you may need to use cutting machine and rasper to grind potato pieces into potato starch slurry. This new rasping way has highly starch release rate because it has the features of high speed and high rasping coefficient,

C.Extracting section: to separate the fiber and starch slurry

Centrifugal sieve is used to separate the fiber and starch slurry, and the machine has good extracting performance of starch from potato, the starch extracting rate can over 94%.

D.Concentrating section: to concentrate and delicate starch mil

And then hydrocyclone station is used to remove fiber, protein and cell sap out of starch milk to concentrate and delicate scrubbing starch milk.

E.Dewatering section: to dewater the wet potato starch

The vacuum filter is widely used for potato starch dewatering. This kind of machine has good starch dewatering effect and can efficiently dewater the potato starch milk into the potato starch powder.

F.Drying section: to dry the potato starch powder

This is the last step for potato starch process, the flash dryer is often applied to dry potato starch. The flash dryer adopts low temperature drying system, which will prevent starch gelatinization. After drying, you can get the final potato starch product.
