Sweet potato starch is quite widely used that the market demand is also large. However, what is the preparation for potato starch process? It is just to prepare some raw materials and buy some equipments for processing sweet potato starch, isn't it ? Now, just have a look at how to do it.
During the processing of sweet potatoes, hot water, cooling, rinsing, and washing equipments all need water. The quality of water from its source could directly affect the quality of sweet potato starch, and the sufficiency of the water source is also concerned with the efficiency of sweet potato starch processing.
Water used should match the standard requirements for ordinary drinking water-- that is, colorlessness, odorlessness, pathogen-free, limpidity, no precipitation, no heavy metals and no toxicity. Its hardness is sugggested between15-16 degrees, and the PH value is appropriate with 6.5-9.5. Water from deep wells and upstream rivers is feasible.
2. To determinate the site of factory and select sweet potato starch processing equipments
The determination of site of sweet potato starch processing manufacturers should meet those three points, water, road and electricity. In addition, the environmental conditions outside the factories should be good and workshops with a ceiling, the ground cemented, and drainage ditches are needed.
Sweet potato starch processing equipments include washing machines, crushing and separating machines, dewatering machines, dryers and the like. We can choose the right type of sweet potato starch processing equipments according to the processing volume. For large processing volume, we can choose the automatic sweet potato starch processing line. Then, according to the demand for starch quality, select a single machine combination of different sweet potato starch processing equipment.
3. To acquire and select sweet potatoes
First of all, the raw materials for sweet potato starch processing is naturally that the higher the starch content the proction has, the better it will. Therefore, choose varieties with high starch content as raw materials. Second, choose sweet potatoes with good quality. Then, try to avoid buying sweet potatoes that have been stored in the cellar, because sweet potatoes will lose starch during storage. We should use sweet potato starch processing equipments to process those sweet potatoes planted by own self into starch as soon as possible. This will not only improve the yield, but also prevent the sweet potatoes from being damaged during storage.
4. To store fresh sweet potatoes
The sweet potatoes are seasonal. For sweet potato processing factories, it will take a certain period to store some sweet potatoes to ensure the uninterrupted production of the factories. Sweet potatoes are harvested with a large number of microorganisms which may cause rot, so it is necessary to master the storage methods.
Cellaring is a relatively common storage method, which requires a temperature of 12-15 degree Celsius and a humidity of 90%. The cellar site should be selected carefully that vent holes should be set at the mouth of the cellar and potatoes should be stacked to facilitate ventilation.
In summary, everything needs to be prepared before processing sweet potato starch, such as, knowing water requirements; the determination of the site and the selection of sweet potato starch processing equipments; the acquisition and selection of sweet potatoes; the storage of fresh sweet potatoes. Among these, the selection of sweet potato starch processing equipments should be paid more attention. Appropriate sweet potato starch processing equipments are of great benefit to the production of sweet potato starch. Appropriate sweet potato starch processing equipment model and single machine combination are very critical to the efficiency and starch quality of sweet potato starch processing.
