The basic technological process of pea starch mechanical processing:

1. Sorting and removing stones, and sorting the purchased dried peas to remove stones and other impurities

2. Soaking, soak the peas in clean water for at least 3 hours, so that the starch can be fully extracted in the later process.

3. Crushing and grinding, and preliminary extraction of starch

Most of the market uses rasp mills and centrifugal sieves to complete the preliminary extraction and filtration of starch. If a special curved-net extrusion type flour mill is used, peas can be squeezed, crushed and filtered multiple times to extract high-concentration starch slurry with low water content. , To facilitate subsequent processing.

4. Filter and purify, remove sand and mud to ensure taste and quality

A variety of machinery and equipment separate the fine fibers and starch in the starch slurry; it is used for starch purification to remove fine impurities and sediment in the starch.

5. Concentrated and refined to improve the whiteness of starch

Further separation of non-starch substances can independently complete the separation, washing, and concentration operations of starch, modified starch, fermentation, and chemical industries.

6. Dehydrate and dry

The starch slurry has a higher water content, and the dehydration treatment improves the purity of the starch; the final drying step quickly removes the moisture in the wet material to achieve instant drying, and then the finished product is bagged.
