how-to-make-potato-starch-potato starch processing machine

Potato starch often appears in gluten-free recipes as a thickener instead of flour. It's not always common at the grocery store, The amount of starch this process yields varies with the age and type of potato used. For the best results, use a large, high-starch russet potato.



 Dry sieve & rotary washing machine

Raw material for starch processing is firstly conveyed to dry sieve, and the inner spiral is rotated and rubbed to remove most of the dirt, sand and debris adhered to the surface of potato. Then potato enters the rotary washing machine to further clean and remove the sediment, so that the material can be cleaned throughly by potato starch making machinery.

- Rasper

Washed potato is transported by spiral into rasper for grinding, and the cells destroyed by the mechanical action of the file will release the starch. In order to increase the extraction rate, an advanced grinding machine with a high grinding coefficient is selected. At the same time, the file of the potato starch making machinery must be rinsed with water to remove the starch attached to the slice.

- Centrifuge sieve & Desander

A centrifugal sieve is a potato starch making machinery that uses its powerful centrifugal force to separate the fibers and starch in the starch slurry so as to remove fiber impurities. While sand remover removes sand impurities from the starch by specific gravity separation.

- Hydrocyclone station

The hydrocyclone system as a potato starch making machinery for starch concentration, refining and recovering, it has the function of remove impurities such as soluble and insoluble proteins in the starch. Meanwhile it can also recover starch.

- Vacuum filter

Vacuum filter uses vacuum negative pressure for starch dehydration. This potato starch making machinery ensures good dehydration effect, wet starch moisture stability.

- Airflow drying

The prepared wet potato starch is pumped to a flash dryer for drying, and its moisture is controlled to be below 14%. Thereafter, the dried large particle material is siefting off by a starch vibrating screen, and 2 to 8 mm of starch powder is prepared by crushing and sieving.

- Automatic packaging machine

According to the user's request, in order to facilitate transportation, the small piece of potato starch is collected and packaged by automatic packaging machine.

    Our company has a large potato starch processing machine, which can produce and process 5 - 100 tons of potato starch a day. If you need to set up a potato starch processing plant, you can contact us.
