What to do to increase the sweet potato starch production in the processing process?

In the process of sweet potato starch production, the production capacity has a great relationship with the economic benefits of sweet potato starch processing plants. In the case of ensuring the quality of sweet potato starch, the larger the production capacity, the higher the market value and the higher the economic benefits. So what to do to increase sweet potato starch production in the processing process?

In sweet potato starch production process, if you want to increase sweet potato starch production, you should pay attention to these four points:

● The quality of sweet potato raw material is bad or not.

● Sweet potato production technology will influence the yield.

● The quality of water used for sweet potato starch production.

● The operation steps of the workers is right or not.

Pay attention to these four points to increase sweet potato starch production

The quality of sweet potato raw material.

Varieties of sweet potato raw materials: different varieties of sweet potato raw materials contain different grade starches content. The starch content of high starch special varieties sweet potato is generally 22% - 26%, and the starch content of edible starch varieties is 18% - 22%. The starch content of edible and feed sweet potato is only 10% - 20%. Therefore, the use of sweet potato raw materials with high starch content can greatly increase the sweet potato starch production in the processing process.

Stacking time of sweet potato materials: Sweet potato raw materials have the highest starch content at harvest. But as the sweet potato raw materials are stacked for a longer time, the greater the ratio of sweet potato starch to sugar, the lower the sweet potato starch extraction rate. In order to increase the sweet potato starch production, the sweet potato raw materials should be processed into sweet potato starch as soon as possible.

The quality of sweet potato raw materials: In the fresh sweet potato raw materials, some sweet potato raw materials with excessive impurities or damage are mixed, which will also affect the sweet potato starch production. Before the production and processing of sweet potato starch, the sweet potato raw materials of good quality should be screened, which can effectively increase the sweet potato starch production in the processing process.

Different quality of sweet potato raw materials

Sweet potato production technology.

Degree of crushing of sweet potato raw materials: Since sweet potato starch particles are present in sweet potato tuber cells, it is necessary to crush sweet potato tubers to free sweet potato starch particles. If the sweet potato raw material is too coarsely ground, the free rate of the sweet potato starch particles in the sweet potato tubers is low, which affects the production of sweet potato starch; if the sweet potato raw material is too finely ground, the instantaneous temperature of the sweet potato raw material rises, causing the sweet potato starch to be easily gelatinized, which affects the separation. So choosing the right sweet potato grinding equipment can effectively increase the sweet potato starch production.

The degree of clogging of the centrifuge sieve machine: The degree of clogging of the centrifuge sieve also has a great influence on the sweet potato starch production. During the production of sweet potato starch, the protein and pectin in the sweet potato starch slurry will absorb water, and the gel formed will easily block the mesh of the centrifuge sieve. In severe cases, more than 60% of the mesh will be blocked , Which will affect the separation of starch. When the blockage is small, the extraction amount of starch is reduced by 5% to -5%, and when the blockage is serious, the extraction amount is reduced by more than 40%. Therefore, the screens should be cleaned or replaced regularly. So it will increase the sweet potato starch production.

The quality of water used used for sweet potato starch production.

The establishment of a sweet potato starch processing plant requires careful consideration of water quality issues. Good water quality not only helps to increase the output of sweet potato starch, but also improves the quality of sweet potato starch. Sweet potato starch should be treated with soft water as much as possible, usually requires clear, colorless, odorless, odorless. There are no precipitation, no pathogens, no hydrogen sulfide and other harmful substances and hardness is 15 degrees which containing calcium oxide 10 mg) or more low, pH value is preferably 6.5-8.5. When the water quality is not good, before sweet potato starch production and processing, it is necessary to filter the water in advance, disinfect, deodorize or soften the water. Only in this way, can we increase the sweet potato starch production.

The operation steps of the workers.

Make sure the operation steps of your workers is right. If the operation in some section is unqualified, it will affect sweet potato starch production in the production process. But don't worry. Because If you buy the sweet potato starch processing machine from Doing Holdings - Henan Jinrui Food Engineering Co., Ltd, our professional engineer will train your workers learning the normal operation steps till they can operate the machines by themselves.
