Through the Sweet potato raw material cleaning and peeling to achieve material purity and ensure the continuity and efficiency of follow-up treatment. The dry sieve and paddle washing machine were utilized to clean Sweet potato raw material. Paddle washing machine is a professional Sweet potato flour processing machine in Sweet potato flour production plant. The material enters the silo filled with water, and the rotated blades roll, pick up, throw, and then rub the materials. The material is thoroughly peeled and washed with good washing results. The device has the characteristics of a novel structure, high efficiency, countercurrent washing, water saving and simple maintenance to ensure the quality of Sweet potato flour production.

After the materials are fed into the hopper through the feeding port. The machine automatically runs continuously upwards. The transfer speed can be adapted according to the transfer amount, and the lift height can be selected as needed. The bucket elevator has the advantages of large conveying capacity, high lifting height, stable and reliable operation and long service life.

2. Second part is Sweet potato grating


After cleaning section is the grating step. Depending on your budget of making Sweet potato flour in Sweet potato flour production plant, you can have a grating machine or a rasping machine.

The performance of the grating machine, otherwise known as the hammer mill, is relatively mediocre.

A mixture is obtained when the defective cells release flour particles, fibers, and soluble substances. This mixture is composed of ruptured and enraptured plant cells. The flour remaining in the unbroken cell wall in the Sweet potato slurry is not extractable in production and is discharged together with the dregs, which is called a combined flour.

The effect between rasper and grating machine is different in Sweet potato flour production plant.  rasping machine is superior speed, high rasping coefficient and good separation effect of combined flour in material. With a rasping rate more than 95%, it is advanced in technology and high efficient in extraction rate.

High extraction rate of Sweet potato flour makes it popular in the processing of Sweet potato flour in Sweet potato flour production plant. The machine with the characteristics of Sweden SKF bearing, Optibelt cog belt, stable operation and long service life.
