[0002] In biological fermentation industry, tetrahydropyrimidine is widely used in medicine, food and cosmetics as an important functional compound. Its production process involves the solid-liquid separation of fermentation broth, which has a direct impact on product purity and activity. At present, the commonly used solid-liquid separation equipment is mainly centrifuge, which separates the solid phase from the liquid phase in the fermentation broth by centrifugal force generated by high-speed rotation.
[0003] In the centrifugal separation process of tetrahydropyrimidine fermentation broth, although most of the solid-liquid separation can be effectively realized by high-speed centrifugation and secondary filtration module, a small amount of tetrahydropyrimidine crystals may still be left in the final obtained liquid phase, which needs to be collected by secondary filtration. This phenomenon is usually related to factors such as small crystal size and close density to mother liquor, which makes it difficult to be completely settled or removed by filtration. In addition, due to the limitation of centrifuge separation precision, part of the small crystals may pass through the filter medium with the liquid phase, thereby affecting the separation purity. Especially when dealing with high concentration fermentation broth, the filter cloth bag pores are easily blocked by small particles, further reducing the filtration efficiency and exacerbating the crystal residue problem.
