Cassava starch manufacturing process

The cassava starch manufacturing process of Doing Company adopts the wet processing technology of starch production without any additives. The process is operated automatically from the whole process of cleaning, washing, grinding, separating, desanding, concentration and refining, dehydration and drying of raw materials.

Here are the detail steps of cassava starch manufacturing process
1. Cassava transportion and weighting: Cassava roots have 24-48 hours shelf-life after harvest, so the roots have to be processed within 2 to 3 days from harvest. Therefore the newly harvested cassava should be transpoprted into factory for processing as soon as possible. Then the cassava is weighted and prepares for cassava starch manufacturing process.
2. Cleaning: The weighted cassava is transported in dry sieve by conveyor to remove the sand, weed, stones and other debris. There is no water needed in this process in cassava starch manufacturing process. The dry sieve is designed with multi spirals which push cassava forward during the cleaning process.  

3.Washing:Then it goes into the paddle washing machine to further wash the attached silt, grave and other impurities in cassava starch manufacturing process. Water is needed for this process. And the machine adopts countflow washing method to improve washing effect.

4. Crushing: The washed cassava is then transported into crushing machine by screw feeder. This is the vital process in cassava starch manufacturing process. The purpose of this process is to  crush cassava into starch so as to releasse starch from cell wall. The breakage rate and extraction rate of the machine determines the final cassava starch yield. DOING rasper is a high efficient machine with a breakage rate more than 94%.
5. Separating: The grinded cassava slurry then enters into centrifuge sieve for separating fiber and starch. The centrifuge sieve takes use of high speed centrifugal force to separate the fiber with starch. In cassava starch manufacturing process, we usually take multi centrifuge sieve for a better separating effect. Then the starch need to be further processed in fine fiber sieve whose function is to remove fine fiber out of starch slurry.

6. Desanding: This process is mainly for remove the sand content out of cassava slurry for it has a bad influence on the taste of cassava starch in cassava starch manufacturing process. The desander is a cassava starch processing machine utilizes the different specific gravity between the cassava starch and sand to remove the sand.

7. Concentration and refining: After desanding, the cassava starch enters into hydrocyclone station for cassava starch manufacturing process. This process is mainly used for separate the fiber, protein and cell sap from starch. DOING full hydrocyclone technology can achieve the concentration, recycling and refining of cassava milk.
8. Dewatering: The widely used machine for the dewatering process in cassava starch manufacturing process is peeler centrifuge whose main function is to reduce the water content of starch milk. It is required that the moisture content of starch milk is about 38% after dewatering.

9. Drying and packing: The dewatered starch is sent to the flash dryer through the screw conveyor for drying. Flash dryer takes use of the high speed hot air to dry cassava starch which is completed just in a few seconds. The whole system is under negative pressure, no dust and energy saving. The moisture content of starch after drying is between 12 and 14%, reaching the standard of finished products. And the starch is packed by automatic packing machine. The whole cassava starch manufacturing process is completed.

Doing Company is a professional enterprise specialize in manufacturing, researching, developing and installation complete set of cassava products deeply processing equipment. The cassava starch manufacturing process adoptes by Doing Company features with large products processing capacity and short production cycle. It only takes more than ten minutes from raw material to the finished product which effectively avoid the browning of materials due to long time of exposure in air. Meanwhile it effectively prevents the secondary pollution of dust and microorganisms and improves the production efficiency and product quality.
