Cassava Starch Production Machine and Process

1. Raw Materials Preparation

The raw materials are the foundation of the cassava starch production line, and the quality of the raw materials will determine the quality of the final produced cassava starch. Therefore, the above - mentioned raw material requirements should be strictly followed.

2. Cleaning and Peeling

The fresh cassava is conveyed to the factory for cleaning and peeling. The raw material rotates and rolls along the cylinder wall, with water as the medium for spraying, washing, bathing, grinding, cleaning, and peeling. The purpose is to remove all the silt, and the peeling rate can reach up to 80%. Then, it will be transported to the shattering section. Main Equipment: Belt Conveyor, Peeling Washing Machine, and Rolling Bucket Washer.

3. Shattering

This process is to destroy the structure of the cassava, allowing the tiny starch particles to break up and separate from the roots. Main Equipment: Hammer Crusher, Knife - type Crusher.

4. Plasm and Dregs Separating

The purpose of separation is to separate insoluble proteins, residual soluble proteins, and other impurities from the starch whey, so as to achieve the purpose of washing, refining, and concentrating the starch milk. Main Equipment: Vertical Type Centrifugal Screen and Pressure Sieve; if it is necessary to extrude the starch residue, add a Starch Residue Extruder.

5. Desanding

According to the principle of specific gravity separation, the starch whey is pumped into the whirlpool by a pressure pump. The bottom flow is used to remove the sand, and the top flow passes through the pulp to achieve the purpose of sand removal. A desander is used to complete this process.

6. Purification

This process usually adopts a Concentration, Purified Hydrocyclone Assembly to complete it.

7. Vacuum Dehydration

After the separation and purification process, the concentrated whey still contains a large amount of water, so it must be dehydrated to facilitate drying. The equipment is a Vacuum Dehydrator.

8. Drying

Through drying, the water content of the starch product is about 13.5%. The equipment is an Air Stream Dryer.

9. Starch Packing and Stock for Sale

The produced starch should be packed directly and stored in a timely manner for sale. An Automatic Packaging Machine is widely used in this section.
