How is potato starch made?

Use potato as raw material to made starch is a good project for potato deep processing, because of potato starch is a basic material for kinds of potato food production, that's to say the potato starch is essential for potato deep processing,also widely used in varities of industrial production and daily life. Then how is potato starch made? Doing Company offer the answer as below:

Technical process:

Fresh sweet potato - cleaning and washing - crushing - starch extraction - filtering and desanding - starch concentration and purification - dewatering  and drying

How is potato starch made

Main machines used for how is potato starch made:

Paddle Washer – Potato Rasper - Centrifuge Sieve - Fine Fiber Sieve - - Hydrocyclone - Vacuum Filter  -- Potato Starch Flash dryer

1, Cleaning parts of potato starch made:

Dry sieve:

Widely used in impurities pre-removal for fresh potatoes for how is potato starch made. It's used to remove dirt, sand, small stones, weeds or other impurities that are attached on the surface of potatoes. It has stable speed so as to make the material free of damage. Easily adjustment according to raw materials features. If the potatoes after harvesting not with too much impurities mixture, then just use the paddle washer is OK.

Paddle washer machine:

Dry sieve no need water, then this paddle washer requests water for potato cleaning, this machine mainly used to wash the raw materials, adopted counter-current washing principle from water to potatoes. By the effect of paddle pushing, the raw material flows in the converse direction against water currently, which makes washing completely and eliminate sand and mud at most. Our potato cleaning parts has stable operation and prevent potato from damage from the drun, which contributes to the extraction rate of how is potato starch made.

2, Crushing parts for potato starch made:

Potato Rasper:

It is widely used for crushing materials. It has features of modern design, compact structure, high seed, high rasping coefficient and high extraction rate. It is one of excellent products developed by Doing Company. It can make a high extraction of bound starch for how is potato starch made. This rasper is a high-efficiency crushing equipment developed by Doing company in combination with advanced technology at home and abroad. Fine crushing performance make sure the high starch yield.

3, Starch extraction part:

Centrifuge sieve:

Used for the extraction of starch from the potatoes of how is potato starch made, remove fiber from potato starch slurry, extraction starch entirely. The precision grade of dynamic balance of sieve basket is G6.3 in order to keep stable operation.

4, Starch concentration and purification:

Disc separation machine:

Disc separator is widely used in processing of starch to separate protein and cell out of starch slurry, with high separating factor, newest technology process of how is potato starch made, better and high efficiency.

Hydrocyclone station

Hydrocyclone Station

It is also used to remove fiber, protein and cell sap out from starch milk to concentrate and delicate scrubbing starch milk for how is potato starch made. It includes 3 steps:concentrating, recovering and washing. Its pipe material is strengthened nylon. Combined with disc seperator to get higher washing effect.

5, Dewatering and drying system:

Vacuum filter:

Widely used for the starch dewatering, final starch water content reach to 38%-42%, make the potato starch moisture suit for flash drying system for how is potato starch made. Starch vacuum filter is also widely used for the starch dehydration in medicine, food, chemical engineering and other industries.

Starch flash dryer:

This generally the last step for how is potato starch made. Adopts low temperature drying system, which will prevent starch gelatinization. Final starch moisture is 12%-14%.

Potato starch drying machine

All the potato starch manufacturing equipment are made of high quality stainless steel, rotating drum speed can frequency control. Cleaning of the drum is using intermittent automatic flushing. Filter slot equipped with paddle stirrer to prevent starch deposition. And it is equipped with continuously adjustable level control. Starch vacuum dewater machine is pneumatic controlled scraping blade discharging and the scraper is made of high hardness alloy.
