potato starch manufacturing process

Production process of potato starch - potato starch processing process

Potatoes are made into edible potato starch through a series of processes. The production process of potato starch includes potato washing machine, crushing, slurry residue separation, desanding, protein separation, pure starch slurry, dehydration, drying and packaging. After a series of treatments, potato starch is obtained.

Equipment required in potato starch production:

Potato dry sieve - U type cleaner - potato crusher - pulverizer - centrifugal sieve - desander - cyclone - vacuum dehydrator - starch dryer - packaging machine

The production process of potato starch is basically the same as that of sweet potato starch. The specific process is as follows:

Wash potatoes

Dry screen and U-type cleaner are required for cleaning. To remove the sand and dirt on the surface of potatoes. Cleaning is the basis for getting clean potato starch.

Crushing and crushing

In the process of potato starch processing, in order to better separate the potato starch granules and fibers, we are equipped with a potato crusher to first crush the potato into small pieces, and then use a grinder to crush the potato into small pieces to achieve the effect of starch separation.

Extraction of potato starch

The starch slurry enters the centrifugal sieve, and small starch granules and proteins are separated from the sieve by centrifugal force and gravity, while potato starch granules are discharged by the slag pump. After that, the potato starch slurry enters the desander, and the sand is collected into the container of the desander, and then the potato starch slurry enters the cyclone group. Cyclone is a potato starch processing equipment with washing, separation, concentration and other functions. After this process, the potato starch paste becomes white.

Dehydration and drying

Vacuum dehydrator is often used in potato starch dehydration. The wet starch milk is dehydrated to the moisture content of about 38% - 40% by a dehydrator. Then, the wet powder is transported to the inlet of the airflow dryer. Through the drying of starch dryer, potato starch is dried to dry starch with water content of about 13%. Then the dried potato starch can be screened by starch sieve to further improve the fineness of potato starch.

Potato starch packaging

Finally, the potato starch packaging machine will package the finished potato starch into 25-50 kg/bag, and the whole potato starch production process will be completed.

From the cleaning part to the final starch packaging, the production process of potato starch only takes about 20 minutes. Kaifeng Sida Agricultural Product Equipment Co., Ltd. explained the production process of potato starch.
