Cassava starch processing line

Cassava can be used for producing various products, such as cassava starch, cassava flour, garri and so on through a series processing procedure. Doing Company is a cassava deep processing manufacturer whose main business covers but not limited to cassava flour processing line, cassava starch processing line and garri processing line.

The following is the cassava processing procedure in cassava starch processing line

1. Choosing: In cassava starch processing line it is vital to complete the whole process within the shortest time possible, since as soon as the roots have been dug up, as well as during each of the subsequent stages of manufacture, enzymatic processes are apt to develop with a deteriorating effect on the quality of the end product. This calls for the short processing time, or in other words, high efficient cassava starch processing equipment.

2. Cleaning: The newly harvested cassava roots contains weed, stone, siol, sand and other debris. Therefore they need to be cleaned first before further processing. Dry sieve is the most widely used cassava starch processing machine for cleaning in cassava starch processing line.

3. Washing: The washing process in cassava starch processing line is used for removing the attached soil, sand, dirt and so on with paddle washing machine and wahsing water. DOING paddle washing machine adopts the counterwater washing principle to save water and improve washing effect.
4. Grinding: The cassava root need to be grinded into slurry in order to release its starch from cell wall in cassava starch manufacturing process. Rasper is the machine used for this purpose. The grinding rate determines the extraction rate of cassava, therefore it is important to choose a high efficient grinding machine for cassava starch processing line. DOING rasper introduces the advanced international technology which can achieve a high grinding rate and high starch extraction rate.

5. Separating: The cassava slurry contains many impurities, such as fiber, protein and cell sap. They need to be separated from starch. Centrifuge sieve and fine fiber sieve are the separating machine serves for separating fiber from starch.  In cassava starch processing line, we normally use four to five stage centrifuge sieve in order to achieve better separation effect. Fine fiber sieve is a low speed centrifugal machine which is mainly for removing fine fiber out of starch. Normally, after the separation of these two machine, the fiber can be effectively removed.

6. Concerntration and refining: This process is used for removing protein, cell sap and other impurities out of cassava slurry. In cassava starch processing line, hydrocyclone station is the extensively used machine for this process. DOING full hydrocyclone technology can achieve the concentration, refining and recycling of starch which not only ensures the high quality of final cassava starch but also prevent the waste of cassava starch in processing.
7. Dewatering: The dewatering process is maily for reducing water content of cassava milk so that it can meet the drying standard. In cassava starch processing line,peeler centrifuge is used for dewatering cassava milk. This machine can shorten dewatering time and increase production capacity by 50%. This is required that the water content of cassava starch is about 38%-40%.

8. Drying and packing: This is the final processing procedure in cassava starch processing line. The dewatered cassava starch enters into flash dryer by feed conveyor and mixs with the high speed hot air flow, and the drying process is completed in just a few seconds by heat exchange. After that, the dryed cassava starch are packed into 25kg or 50kg according to different requirements.
