Sweet potato starch processing plant

Sweet potato starch processing is a physical separation process,which separate the starch from the fiber, protein and other impurities by sweet potato starch extraction machine.The process of sweet potato starch processing plant mainly includes the following part:
sweet potato choosing-cleaning-washing-cutting and crushing-separating-concentraction and refining-dewatering-drying-packing

Accordingly, here is the sweet potato starch extraction machine used in sweet potato starch processing plant
dry sieve for cleaning-rotery washing macine-cutting machine-rasper for crushing-centrifuge sieve and fine fiber sieve for separating-hydrocyclone station for concentraction and refining-vacuum filter for dewatering-flash dryer for drying
1. Cleaning and washing machine
a.Sweet potato cleaning machine: Before cleaning the sweet potato, it is important to choose good raw material. Then the choosing sweet potatoes are transpported into the cleaning machine in sweet potato starch processing plant. The machine used to clean the sweet potato is dry sieve which can effectively remove the soil, sand and other impurities in the sweet potatoes.

b.Sweet potato washing machine: The purpose of this process in sweet potato starch processing plant is to wash the sediment in the outer cortex of sweet potatoes. And the used machine in this process is rotary washing machine. By adopting the countercurrent principle, the sweet potato moves forward, while the water moves in the opposite way, thus the material can be washed thorough.

2.Starch extraction machine
a.Cutting machine: After cleaning and washing processs, the sweet potato is converted to cutting machine in sweet potato starch processing plant. The main purpose of cutting sweet potato is to make the crushing easier.By cutting the sweet potato into small pieces, it ont only make the crushing more thuroughly but also reduce the possible damage caused to the rasper machine.
b. Crushing machine: After cutting, the broken pieces goes into the crushing machine. The extensively used crushing machine is rasper. As the most important machine in sweet potato starch processing plant, DOING rasper adopts Sweden SKF and Germany Optibelt technology which offers high crushing efficiency and longer service life.

3. Starch separating and refining machine
a.Separating machine: After crushing, the sweet potato slurry includes many fiber, protein, cell sap and other impurities. They need to be separated from starch in sweet potato starch processing plant. And in this process, we need centrifuge sieve and fine fiber sieve.The centrifuge is used to separate the fiber and starch by using the high speed centrifugal force.

b.Concentraction and refining machine: After a series of separating process, the fiber is almost removed. Then it is concentraction and refining process. Hydrocyclone station is the mainly used sweet potato starch processing machine in sweet potato starch processing plant. The function of hydrocyclone station is to remove the fine fibers, protein and cell sap out of starch milk so as to achieve the purpose of concentration and refining.

4. Starch dewatering and drying machine
a.Dewatering machine: Even after the concerntrion, the water content in the starch milk in still high. The starch vacuum filter is used for the dehydration of the starch milk in sweet potato starch processing plant. The vacuum filter is a continuous running machine which using the moving filter cloth as the filter medium and using the negative pressure and gravity provided to separate the solid from liquid.
b.Drying machine: The dewatered starch need to be dryed to meet the standarded starch.This sweet potato starch processing machine is called flash dryer in sweet potato starch processing plant.The flash air utilizes the high speed hot air to dry the starch which is complete in seconds.DOING flash dryer has the advantages of fast drying speed, high efficiency, high equipment production capacity and low equipment cost.
