The processing technology of potato and pueraria starch can be simply summarized as: washing-pulverizing-sieving-refining-dehydration-drying. The most important influence on the starch extraction rate in these links is the crushing, sieving and refining sections, drying section. As long as the water content of the starch is controlled, there is almost no effect on the starch yield.

The purpose of comminution in the production of potato starch is to break the cell wall of potato tubers as much as possible to maximize the exposure of starch granules. Because the fiber content of potato (especially cassava, pueraria, sweet potato) is large, it can not be broken too fine, otherwise it will affect the separation and refining effect of starch. The effect of crushing is generally expressed by the starch liberation rate. According to expert research, it is found that the equipment with good crushing performance has high starch detachment rate when the processed potato varieties are the same and the processing water volume is the same. The quality of the crush is directly related to the free effect of starch, and the high starch free rate is a prerequisite for high starch extraction rate.
New Sweet Potato Powder Machine Creates Efficient Starch Extraction Rate
In order to solve this problem, Goodway Potato Machinery combines the foundations of domestic and foreign potato processing equipment and technology, and combines with traditional craftsmanship to extract refined and inferior to design and manufacture the curved mesh extrusion type potato starch machine from the practice of more than ten years. it specially. It is especially suitable for processing high-fiber, high-yield potato starch.

Curved mesh extrusion type potato starch machine
The curved mesh extrusion type potato starch machine integrates the crushing of fresh potatoes, separation of pulp and fine filtration. Its unique features are reflected in:
①The pulverizing system uses 2345 pulverizing filtration technology. The unique extraction process of multi-stage pulverization, multi-stage scouring, multi-stage filtration and multi-stage extrusion has high starch extraction rate. This greatly increases the material separation rate and reduces the overall energy consumption.

② Two-stage crushing is more scientific. The first stage uses honing pulverization, and the second stage uses hammer pulverization. The combination of the two fully compensates for the defects. The combination of sieving and pulverization, the primary honed material is first sieved to remove most of the starch and viscous material. This can reduce the viscosity of the material and reduce the retardation of the material during secondary pulverization, thereby reducing the overall energy consumption. Using the principle of sorting and pulverizing, the material that does not meet the requirements is crushed a second time. This is to further improve the fineness of the potato residue and increase the starch extraction rate, thereby saving power, improving efficiency and ensuring uniformity of materials.

③Three-stage extrusion can save energy and save water and promote extraction. After four levels of panning and five levels of filtration, the extraction is complete. After repeated extrusion and panning, the starch is freely free, which overcomes the defect that it is difficult to filter by only one filtration, and greatly improves the extraction rate of starch. The starch is completely freed, and the starch and the potato residue are sufficiently freed by prolonging the washing time and increasing the filtration strength. After pulverization/panning/pressure filtration multi-stage circulation, the starch liberation rate can reach over 98%, and the starch extraction is more thorough. The ultimate material has a low moisture content and is convenient for the next step. Biomimetic robot feeding improves processing efficiency by more than 30%.

In addition, continuous high-efficiency operation of pulverization and multi-stage separation shortens the contact time of starch with oxygen, avoids the browning of starch due to oxidation, makes the starch white and white, and has good quality. It is used for making powders such as fans and is transparent and tough. Use the appropriate smashing method to maximize the extraction rate of potato starch using professional pulverizing equipment. Through high-quality starch control through strict process control, high economic benefits are obtained, and the production interests of customers are guaranteed.

Goodway will continue to use the professional potato starch processing equipment to help the development of sweet potato deep processing in the field!
