What does a cassava starch processing chain consist of？

The cassava starch processing chain consists of several key stages, each crucial for transforming raw cassava into high-quality starch. Here we will introduce the main stages of cassava starch processing chain.

Cleaning and Washing

The first stage of cassava starch processing chain is cleaning and washing. Here we need to remove the big impurity from fresh cassava with a dry sieve , and then wash them by using a paddle washer, so that the raw cassava tubers are clean enough for next processing step.

Grinding

Then it comes to the grinding stage. In the cassava starch processing chain, this stage is to release more starch from cassava , thus increasing starch yield. The machines we use in this grinding stage are a cassava cutting machine and cassava rasping machine. The cutter is used for cutting the big size cassava into small pieces, then rasper will be used for crushing cassava completely.

Separating

The separating stage in the cassava starch processing chain is to screen big fibers from starch slurry, thus primarily improving the purity and taste of cassava starch. Machines often used here is centrifuge sieve, which can extremely and efficiently remove large fibers of cassava, meeting the final requirements of qualified cassava starch.

Purification

In the cassava starch processing chain, the purification is the most important one compared with other stages as it decides the quality of cassava starch. Factors that influence starch quality include whiteness, purity, fibers, moisture, ash content, etc. This stage configured 18-stage hydrocyclone station aims to remove cell sap, proteins, and other non-starch components. The extraction machine combines concentration, recycle and refinery in one to achieve a better purification effect.

Dewatering

The purified cassava starch slurry is dewatered to reduce moisture content, typically using a peeler centrifuge to reduce the moisture to 38%-40% for the next drying process.

Drying

The drying stage in cassava starch processing chain is to achieve the desired moisture level (usually around 12-14%). The drying machine we used is flash dryer. It adopts negative pressure drying principle to reach a better drying effect. This machine can not only be used for drying cassava starch, but an ideal one for drying cassava flour, potato starch flour, sweet potato starch flour, etc.

Sifting and Packaging

The last stage of cassava starch processing chain is sieving and package. A sifter screen is often used to sieve the final dry starch. The qualified fine powder then will transported into a packing machine for package.
