Factors Affecting the Extraction Rate of Cassava Starch

This year, starch price is going up, so the cassava starch project is more and more popular and many people want to start the business. During preparing the project, there are some problems that are more concerns, like the starch extraction rate, what factors affect the starch extraction rate? Here we will introduce it.

From a large perspective, there are mainly two factors that affect the extraction rate of cassava starch: one is raw material; another one is processing technology and machine configuration.

Factors that affect the extraction rate of cassava starch

1. Raw material

Usually, we need to see the starch content from cassava raw material. Starch content is high in cassava raw material, then we can get more starch. For example, in Southeast Asia, cassava raw material usually with high starch content which is about 28%-30%, even more than 30%, so about 3tons cassava can produce 1ton starch; but in Africa, the starch content from raw material is about 23%-25%, or less than 23%, so about 4tons or more than 4tons cassava can produce 1ton starch. So raw material is one of the important factors.

2. Processing technology and machine configuration

The extraction rate of cassava starch is also related to what processing technology and machine configuration you choose.

Now more advanced is the full swirl processing technology, compared with the traditional precipitation method, the new technology is higher efficiency, high yield, and the final product with high quality.

On machine's configuration, it also affects the extraction rate of starch. In current full swirl processing technology, the Grinding machine, Separating machine, De-sander, Hydrocyclone, and Drying machine all affect the extraction rate. The crushing rate of the equipment and the ability to remove fiber all affect the starch extraction, the crushing is complete, the more fiber is removed, the higher the starch extraction rate.

For example, the rasper is the most advanced machine in grinding part, its crushing rate can reach 96%, so more starch can be released. But another type of crushing machine is the Hammer mill, the crushing rate is about 80%, which means there is still a lot of starch that has not been released, so you will get less starch.
