Is the fineness of thiamine particles caused by the maturation of the mother liquor? Is it still caused by an excessively low centrifugal crystal ratio?
First, check the crystal ratio; second, the washing water in the centrifuge should not be too much.

The issue of small particles in ammonium sulfate is mainly caused by the following factors: 1. Problems with the acid addition process; it is necessary to maintain a relatively balanced acidity level in the mother liquor； 2. Regarding the issue of circular stirring, it is necessary to have a sufficient level of circular stirring to ensure uniformity in the temperature and acidity of the system’s mother liquor ； 3. Prevent the entry of impurities, reduce the formation of nuclei, and avoid the thickening of the mother liquor ； 4. Increase the crystal-to-product ratio.
That’s what was said upstairs! But the first point depends on management; here at us.................
