Sweet potato starch processing plant

The production process of sweet potato starch is a physical separation process, which is to separate the starch from cellulose, protein, inorganic substance and so on.  The Doing Company sweet potato starch processing plant can automatically complete the whole process of cleaning, washing, crushing, separating, concentration and refinement, dehydration, drying and packaging of sweet potato.

Here is the detail analysis of DOING sweet potato starch processing plant
1.Raw material preprocessing section:
(1). Raw material choosing and receiving section:  As the first section in sweet potato starch processing plant, the raw material choosing plays an important role in the final starch quality.  Therefore it will be better to choose high quality sweet potato without damage, no deterioration and no moth. Then the chosen sweet potatos are hauled to the storage yard after being weighed.

(2). Cleaning and washing section: The cleanness of the material have an vital influence on the end products, therefore the cleaning and washing section are important in sweet potato starch processing plant. In this section the attached sand, dirt, weed, soil and other debris of sweet potato are first cleaned in dry sieve and then washed by rotary washing machine.

2.sweet potato starch extraction section:
Grating section: Then grating process is the most important procedure in sweet potato starch processing plant for it determines the starch extraction rate of end products. The rasper is a high efficient sweet potato starch machinery with higher extraction rate produces more sweet potato starch.

3.Sweet potato starch separation and refining section:
(1). Separating section: Separating section is another key process in sweet potato starch processing plant that affects the extraction rate of sweet potato starch. Its main purpose is to separate the fiber from starch. And the widely used separating machine includes centriguge sieve and fine fiber sieve. The fine fiber sieve is a low speed centrifugal device which is mainly for the separation of fine fiber from starch.

(2). Concentration and refinement section:  Hydrocyclone station is used in sweet potato starch processing plant to remove protein, fiber and cell sap out of starch.  A complete hydrocyclone technology includes the concentration, refining and recycling of starch.

4.Sweeet potato starch dehydration and drying section:
(1). Dewatering section: The water content of starch milk coming out of hydrocyclone station is too large to dry directly. Therefore, it is necessary to dewater starch milk first, so that the water content of starch is about 38%-40%. In the sweet potato starch processing plant, the widely used dewatering machine is vacuum filter.

(2). Drying and packaging section: The purpose of drying in sweet potato starch processing plant is to dry the dehydrated starch to the desired moisture content to meet market standard. The air is heated to the required temperature through the filter net through the heat exchanger, and the hot air is sucked into the flash dryer by the fan. Then the final sweet potato starch is packed by semi-automatic machine for storage.
