The detail introduction of the extraction of starch from sweet potato procedure

1. Cleaning and washing unit: Cleaning and washing is an important process for extraction of starch from sweet potato procedure. It is cleaned to ensure the flawless taste of starch. This is the basic quality of cassava starch. Commonly used cleaning equipments is dry sieve which uses bionics principle to remove the sediment on the sweet potato. Then the materials enter the rotary washing machine for further cleaning and rinsing, improving the cleanliness of the potato and at the same time having a peeling effect.

2. Grinding unit: The rasper is used to crush the fresh sweet potato for extraction of starch from sweet potato procedure. Rasper is used for this purpose. DOING rasper is designed and manufactured on the basis of international advanced technology. The breaking rate can reach up to 95%. The grinded starch features with moderate granules, high quality and high yield.

3. Slurry and slag separation unit: Separation of starch slurry and residue is an important part of extraction of starch from sweet potato procedure. This process and the crushing process determine the yield of starch. Centrifuge sieve and fine fiber sieve are used for separating starch slurry and the fiber impurities.

4. Starch slurry desanding unit: According to the principle of separation of specific gravity, the starch slurry is pumped into the desander by a pressure pump. For extraction of starch from sweet potato procedure, this process is used for removing sand and improving starch taste.

5. Protein separation unit: Hydrocyclone station is used in this process for extraction of starch from sweet potato procedure. The starch is further concentrated and refined to remove non-starch components such as protein to improve the quality of the starch.

6. Starch dehydration unit: The refined and concentrated starch slurry is dehydrated by vacuum filter to achieve the moisture content required for drying (38%-40%). Vacuum filter can achieve automatic and continuous working for the whole dehydration process of extraction of starch from sweet potato procedure.

7. Starch drying and packing: The wet material enters the drying pipe of flash dryer from the feeding machine. In the extraction of starch from sweet potato procedure, flash dryer takes use of high speed airflow to dry the wet starch to meet the required standard.

This is the entire introduction of extraction of starch from sweet potato procedure. Doing company has been committed to the research and development and manufacturing of sweet potato starch processing machine. The equipment produced by Doing Company can complete the whole process from the input of raw materials to the finished starch.
