The whole plant of starch extraction from sweet potato is comprised of five major sections: Washing & Crushing Sections, Screening Sections, Concentrating Sections, Drying Section and Packing Section. We doing company own our factory and entire processing line of starch extraction from sweet potato, so we can offer you the best service, production and competitive price of sweet potato starch extraction.

The process of starch extraction from sweet potato includes these main machines: Dry Sieve, Paddle Washing, Cutting, Rasper, Centrifuge Sieve, Fine Fiber Sieve, Hydrocyclone Station, Vacuum Filter, Flash Dryer, Starch Sieve, Packing machine.

Main machines used for starch extraction from sweet potato

The detailed information of starch extraction from sweet potato on the following.

The first one is washing section. Dry sieve can effectively remove dirt, sand and small stones, it has the ability to avoid sewage disposal. According to multiple spiral operation, paddle washing machine can remove silts and impurities from the surface of sweet potato. At the same time, the outer peel of cassava will be simply handed by these two machines. This section also can be performed manually. The section is the very beginning step of starch extraction from sweet potato.

The second one is crushing section. It includes cutting machine and Rasper, cutting machine can cut sweet potato for primary crushing; Rasper is best for filing and fragmentation, so that the crushing rate will be higher. It has the features of modern design, compact structure, high speed, high rasping coefficient, even particles, high extraction rate. The advantage of it is to reduce the amount of work the next section needs to do.

The third one is screening section, in the beginning, centrifuge sieve is mainly used to separate the fiber and starch slurry. The machine is easy for installation and maintenance and with high efficiency of starch sieving. Material is stainless steel to ensure sanitation.

Then the machine fine fiber sieve will be used in the section to get rid of fine fiber in crude starch. The advantages of these two machines are higher throughput, low energy consumption and good effect of starch extraction from sweet potato.

Hydrocyclone in Doing factory under manufacturer

The fourth is concentrating section:

a. Hydrocyclone station can remove fiber, protein and cell to further process starch milk. The hydro cyclone pipe made of strengthened nylon.

b. Vacuum filter is a solid-liquid separation machine which is formed by vacuum pressure and vacuum filtration. It is the negative pressure formed at the outlet of filtrate as a driving force for filtration. The basic principle of vacuum dehydrator for starch making is that under the action of vacuum negative degree(0.04-0.08MPa), the liquid in suspension is withdrawn through filter cloth, while solid particles are withheld.

The filth is drying section, flash dryer is able to reduce the loss of starch depends on negative pressure system and guarantee the high standards of final project.

The sixth is sieving section, the function of starch sieve is classification the starch in accordance with the different mesh.

The seventh is packing and automatic control system.

Welcome to DOING

It is all the introduction of starch extraction from sweet potato showed in the above. Sweet potato can made into sweet potato starch and it has high economic value, so the plant of starch extraction from sweet potato will have acquire high return on investment.
