The preparation method of edible cassava starch

Edible cassava starch is produced from fresh cassava roots. The preparation method and process are cassava cleaning, washing, cutting, crushing, fiber separating, de-sanding, protein and cell liquids, dehydrating, drying, and sieving. The article will have a detailed introduction to the preparation method of edible cassava starch.

The preparation method of edible cassava starch can be divided into three parts: raw cassava cleaning, starch extraction, and drying.

The Dry sieve machine and paddle washer are used in the cleaning section

Raw cassava cleaning

Cassava tubers attach lots of impurities after harvesting from farm fields. Therefore, cleaning cassava is required before preparing edible cassava starch. The Dry sieve machine and paddle washer are used in the cleaning section. The dry sieve will first remove impurities attached to the surface of cassava roots, and then the paddle washer machine will clean the cassava thoroughly.

Cutting and crushing process for cassava starch extraction

Cassava starch extraction

This is the key part of the preparation method of edible cassava starch, which will influence starch yield and starch quality. After cassava is cleaned well, the next is the cutting and crushing process, releasing starch as much as possible. The rasper machine is used for crushing purposes, it is the key equipment to ensuring a high starch extraction rate.

After crushing, what we get is cassava mash. Cassava mash will first be pumped into a centrifuge sieve machine to separate fibers, and then cassava slurry will go through a de-sander machine to eliminate tiny sands after the slurry is pumped into a hydrocyclone station. The hydrocyclone station is used to separate protein and cell liquids, getting purified cassava starch milk output. The 18-stage hydrocyclone station is applied here to ensure high cassava starch quality and high starch yield.

Cassava starch drying

We can get purified and concentrated starch milk from hydrocyclone. The next process is to dehydrate and dry it. To ensure a better dehydration effect, a peeler centrifuge is used here, from which we can get wet cassava starch with a moisture content of around 38%. After that, the wet starch powder will be transported into the flash dryer, and finally, we can get dried cassava starch. To ensure high quality starch, a sieving machine is installed after the flash dryer.
