Industrial sweet potato starch extraction machine in sweet potato starch process line

Sweet sweet potato starch processing machine
sweet potato starch processing machine includes cleaning and washing machine, crushing machine, separating and refining machine, dewatering and drying machine. For each machinery in the processing process of sweet potato starch, we have corresponding equipment. They are dry sieve, paddle washer, cutting machine, rasper, centrifuge sieve, fine fiber sieve, desander, hydrocyclone, peeler centrifuge, flash dryer.

Then, I will introduce these sweet potato starch processing machines play the role in the production of sweet potato starch.

(1)Cleaning and washing process

After the sweet potato is put into the feeding hopper, it is conveyed by belt conveyor to dry sieve. Dry sieve removes impurities such as dirt, sand and weeds that are attached to the sweet potato surface. After pre-cleaning sweet potato with dry sieve, rotary washing machine uses the countercurrent washing principle to further remove the sediment and other impurities on sweet potato surface.

(2)Crushing process

In order to make the sweet potato fully crush, sweet potato starch processing machine crush is divided into two steps. Firstly, the cutting machine precrushes the washed sweet potato and cuts them into pieces. Then, the rasper crushes the sweet potato pieces into pulp.

(3)Separating and refining process

Separation and refinement are crucial in the processing of sweet potato starch. So in this process, the sweet potato starch processing machine is divided into four steps. The fiber in sweet potato pulp is separated by centrifuge sieve, the fine fiber in the sweet potato starch pulp is removed by fine fiber sieve, the fine sand in the starch is removed by desander to ensure the quality of sweet potato starch, and the protein and cell fluid in the sweet potato starch milk are removed by hydrocyclone to refine and concentrate the sweet potato starch milk.

(4)Dewatering and drying process

Starch milk is dewatered in vacuum filter. After dewatered, sweet potato starch is formed. sweet potato starch needs to be quickly dried in flash dryer to control the moisture content of starch more standardized. The dried sweet potato starch is sifted through the sieving machine, and the finished sweet potato starch is finally put into the packing machine for bagging.
