Why are there no crystals in the centrifuge after using dichloromethane to decompose fats?
What centrifuge? Is the filter screen not selected properly, or is the crystal form unstable? Ask the people in charge of the process.
Solid-liquid separation is generally carried out using a centrifuge. To achieve solid-liquid separation, it is essential to determine the process parameters accurately – that is, what is the solid content in the mother liquor? What is the allowable solid content in the mother liquor after separation? How much traffic do you have? It is based on these parameters that the rotation speed of your centrifuge, the mesh size of the screen, and its specific model can be calculated and designed. It is recommended that you conduct a comprehensive inspection from the aspects mentioned above.
