This article will introduce the processing process of potato starch in detail, and analyze its application trends in the market based on hot topics in the past 10 days.
1. Processing process of potato starch
The processing of potato starch is mainly divided into steps such as cleaning, crushing, filtration, precipitation, and drying. The following are detailed processing steps:
| steps | Operation content | Things to note |
|---|---|---|
| 1. Cleaning | Put the potatoes into the washing machine to remove soil and impurities | Make sure the potato surface is clean to avoid impurities affecting the starch quality |
| 2. smash | Use a grinder to grind potatoes into a pulp | Crushing should be thorough to increase starch extraction rate |
| 3. Filter | Separate starch slurry and residue through screen | The mesh size of the sieve needs to be selected according to the size of the starch granules. |
| 4. Precipitation | The starch slurry is left to stand and the starch settles to the bottom. | The precipitation time needs to be sufficient to ensure the separation of starch and water. |
| 5. Drying | Dry the wet starch until the moisture content is less than 15% | The temperature should not be too high to avoid starch gelatinization |
