Cassava starch processing plant

Cassava, as a high quality starch raw material, is widely used for cassava starch processing plant. With the development of cassava starch industry, cassava starch processing technology and cassava starch processing machine have been updated to meet higher market standard. As a professional manufacturer of cassava starch processing machine, our cassava starch processing technology is the result of our company's many years of experience and the efforts of our engineers.

Cassava starch processing plant

1. Pretreatment of cassava
a. cassava weighing and conveying: This is the first step for cassava starch processing plant. The cassavaes are weighed on the weighbridge and stored in the cassava yard. Then the raw materials are transported by conveyor to the cassava cleaning and washing machine where the stones, sand and other attached objects are separated.

b.Cleaning and washing: In cassava starch processing plant, the main purpose of this process is to remove the sediment from the outer cortex of cassavaes and wash the epidermis of cassavaes. The fresh cassava is cleaned in dry sieve in which the impurities are cleaned such as sand and small stones. Then we use the rotary washing machine for removing the soil, sand and other impurities. This process is the basis of guarantee the quality of starch, the cleaner the raw cassavaes are cleaned, the better the starch quality is.

2. Starch extraction process
a. Crushing: The role of crushing is to destroy the structure of cassava, so that tiny starch granules can be disintegrated and separated from the roots of cassava. In cassava starch processing plant, the widely used crushing machine is rasper. The cassava starch extraction machine relies on high-speed operation to disintegrate cassava so that the starch granules are continuously separated. And the disintegrated cassava is processed into starch slurry by using water as a medium.

b. Separating: Separating section is another key process for cassava starch processing plant that affects the extraction rate of cassava starch. Its main purpose is to separate the fiber from starch.And normally we use multi stage centrifuge sieve for the separating process so as to achieve better separating effect.

c. Protein separation: In this process, we designed a 14-stage concentrated hydrocyclone station for cassava starch processing plant. And the process water is pumped from the other end of the cyclone station to wash the starch in a countercurrent manner. The multi-stage washing can ensure the washing effect of the cyclone station, better remove the impurities such as fiber and protein contained in the starch milk.

Cassava starch drying machine

3.Starch dehydration and drying process
a. Dehydration: The dewatering process for cassava starch processing plant is mainly for reduce the water content of the wet starch. By adopting negative press principle, vacuum filter can effectively reduce the water content of starch so that it can be dried in the flash dryer. After dewatering, the water content of starch milk first should be about 38%-40%.

b. Drying and packing: The wet starch dehydrated by vacuum filter is transferred to flash dryer for drying. It is required the moisture content of the finished starch is about 13.5% after drying process for cassava starch processing plant. Then the starch is packed for storage. And this process requires a sufficient number of bags, a firm package, and timely storage.
