The raw materials for cassava starch includes fresh cassava and cassava stem. They are the main materials for cassava start processing, so the raw materials should be of high quality, fresh. It is best to buy the cassava and immediately send to the factory at each day, and process the wood part and other mixed wood part that is no mud, no sand, no root. Different cassava starch processing is relatively complicated. The detailed cassava starch production process and process is followed as below.Raw Materials Preparation The raw materials are the basics of the cassava starch production line and the quality of raw materials will decide the quality of final produced cassava starch. Therefore, above mentioned raw materials requirements should strictly follow.Cleaning and PeelingThe fresh cassava is conveyed to the factory for cleaning and peeling. The raw material rotates and rolls along with the cylinder wall, spraying, washing, bathing, grinding, cleaning and peeling with water as the medium. The purpose is to remove all the silt and the peeling rate will up to 80%. Then, it will be transported to shatter section. Main Equipment: Bel Conveyor, Peeling Washing Machine and Rolling Bucket Washer.ShatterThis process is to destroy the structure of cassava, which allows the tiny starch particles to break up and separate from the roots. Main Equipment: Hammer Crusher, Knife-type Crusher.Plasm and Dregs SeparatingThe purpose of separation is to separate insoluble proteins and residual soluble proteins and other impurities from starch whey, so as to achieve the purpose of washing, refining and concentration of starch milk. Main Equipment: Vertical Type Centrifugal Screen and Pressure Sieve; If need extrude starch residue, add Starch Residue Extruder DesandingAccording to the principle of specific gravity separation, the starch whey is pumped into the whirlpool by pressure pump, the bottom flow is removed from the sand, and the top flow through the pulp to achieve the purpose of sand removal. Dessander is use to complete this process.PurificationThis process usually adopts Concentration, Purified Hydrocyclone Assembly to complete it. Vacuum Dehydration After the separation and purification process, the concentrated whey still contains a lot of water, so it must be dehydrated to facilitate drying. The equipment is Vacuum Dehydrator.Drying By drying, the water content of starch product is about 13.5%. The equipment is Air Stream Dryer. Starch Packing and Stock for Sale The produced starch should packed directly and timely stored for sale. Automatic packaging machine is widely used in this section.We are engaged in offering a wide range of Cassava Starch Processing Machines that is used for extracting starch from the cassava.
