FAQ / Leave Message / Chat Online 10-23,2018

Tapioca starch is mainly used as raw materials in food, sugar, medicine, feed, textile, paper, chemical and other industrial sectors. The tapioca starch production process is a physical separation process, that is, separating the starch in the raw material from other substances such as fiber, inorganic matters and the so on. In the production process of how to make tapioca starch from cassava, according to the properties of starch is insoluble in water and the specific gravity of the starch, water and special mechanical equipment are used to separate the starch from the water suspension, thereby achieving the purpose of recovering the starch.

The production process of how to make tapioca starch from cassava is divided into the following part:

Weighing and conveying, cleaning, washing, grinding, separation, desanding, concentration and refining, dehydration, starch drying and packaging processes.

Unit 1.Raw material weighing and conveying

Due to the short storage time of cassava roots, it is essential to complete the entire process of how to make tapioca starch from cassava as soon as possible. The newly harvest cassava is firstly weighed by the weighbridge and stored in the cassava yard for storage. Then the weighted cassava is transported by a belt conveyor to cleaning machine for processing.

Unit 2. Cassava cleaning

Then it's time for the cleaning, which receives the raw material via belt conveyor. The machine used for cleaning is dry sieve whose main function is to remove the stone, weeds and other objects for the process of how to make tapioca starch from cassava. After that the cassava enters the washing process.

Unit 3. Cassava washing

After cleaning, the cassava is transported into paddle washing machine where the mud, dirt, soil and the skin of the cassava are removed. After the two process of cleanings and washing for how to make tapioca starch from cassava, the mud, sand and other impurities on the surface of the cassava have been basically removed, and the outer peeler are roughly removed.

Unit 4. Cassava grinding

In the processing of how to make tapioca starch from cassava, it is vital to release as much as free starch from cassava roots as possible. For the more free starch is obtained, the more starch yield is gained. Therefore grinding plays a vital role in the cassava yield. Rasper is the widely used cassava grinding machine whose main function is to destroy the structure of the cassava, so that the tiny starch granules can be released from the roots of the cassava.

Unit 5. Starch slurry and residue separation

The separation unit is the next step of the how to make tapioca starch from cassava, and the used machine normally comprises centrifuge sieve and fine fiber sieve. The main function of this process is to separate the fibers out of starch slurry. After this process, the starch has reached the commercial standard of finished product in terms of fineness.

Unit 6.Starch slurry desanding

The handling of the starch in this stage is mainly for removing sand out of starch slurry so as to improve the starch taste for how to make tapioca starch from cassava. Desander takes use of density separation method achieving the sand removing purpose.

Unit 7. Concentration and refining

The starch slurry after desanding process still contains organic and inorganic impurities such as protein, cell sap and so on, which need to be further processed for how to make tapioca starch from cassava. Hydrocyclone station is used for this purpose. Full hydrocyclone technology can achieve the concentration, refining and recycling of starch.

Unit 8. Starch milk dehydration

The function of this process for how to make tapioca starch from cassava is to reduce water content of starch slurry to meet the requirements of drying. Peeler centrifuge is a high efficient machine used for starch dehydration. After dehydration, the water content is about 38%-40%.

Unit 9. Starch drying and packing

The starch undergoes thorough drying process to meet the requirements of the commercial product for the process of how to make tapioca starch from cassava. After drying, the water content is about 14%.Then it is packed by semi-automatic packing machine for for marketing.

This is the entire process for how to make tapioca starch from cassava.
