How to make potato starch?

Potao starch is a potato deep processing products. But how to make potato starch? As a enterprise specializes in the manufacture, R&D and installation the complete set of potato starch processing equipment, in addition to professional processing equipment, Doing Company can also provide the answer for the question of how to make potato starch.
Here is the introduce of DOING potato starch processing line for how to make potato starch：
1. Potato receiving: this is the first step for how to make potato starch. The fresh potatoes are firstly weighed and stored in the potato yard in potato starch processing plant. Potatoes are fed to potato cleaning machine where they are separated from other debris.

2.Cleaning and washing: Then the potatoes are transported to dry sieve to cleaning the small stones, dirt, sand and other impurities by conveyor for the process of how to make potato starch. After that, they are washed in a rotary washing machine. Then the washed potatoes are transported to the temporary storage hopper through the inclined belt conveyor.

3.Grating: For the whole process of how to make potato starch, crushing is an important potato starch manufacturing process because it determines the extraction rate of potato starch. Therefore it is important to choose a high crushing coefficient machine to deal with this process. DOING rasper is a machine fully absorbs the advanced international technology which can effectively crush the potato.
4.Starch screening: This process for how to make potato starch is mainly to separate the fiber and starch. The mainly used machine in this stage are centrifuge sieve and fine fiber sieve. Centrifuge sieve takes use of high speed centrifugal force to roughly separate the fiber and starch. To improve the separating effect, we need five-stage centrifuge screening process. We can design the process according to customer's requirements. And the fine fiber sieve is used for further separating fine fiber and starch.

5.Starch concentration and refining:  Hydrocyclone station is the potato starch processing machine used for concentrating and refining process for how to make potato starch. Clean water enters from last stage of cyclone station, and wash the mixed with starch milk , then the overflow mixed with the next level starch milk to wash and separate. The countercurrent washing discharges fiber and cell SAP with water vortex. The adoption of grade 13 washing can ensure the washing effect of the cyclone station.

6.Starch dewatering: The water content of starch milk coming out of hydrocyclone station is too large to dry directly. Therefore, it is necessary to dehydrate starch milk first for how to make potato starch. And the water content of starch is about 38%-40% after dehydrating. Doing Company manufactured vacuum filter can effectively reduce the water content of potato starch to 38%.
7.Starch drying and packing: The final process for how to make potato starch is drying and packing. The dehydrated starch cake is transported to the feed inlet of the flash dryer through the conveyor belt and enters the hoist through the feeder. The heat source of flash dryer is steam heat exchanger. After drying, starch is separated from air in a set of cyclone separators. It is then transported to the semi-automatic packaging machine and packaged into 25kg finished products. And the packing specifications can be designed according to customer's need.

This is the entire process for how to make potato starch. Henan Doing Mechanical Equipment co., Ltd can not only offer potato starch processing equipment but also provide plant engineering design and even installation and processing technology training service.
