1. If the product quality is not affected by the presence of air at a higher temperature, it can be recovered at normal pressure first, and when the temperature exceeds the normal pressure boiling point of the desolvent by 10 degrees, when the solvent cannot be evaporated, change the receiving bottle, and then reduce Pressure, the degree of vacuum rises slowly from -0.01mpa to the maximum according to the flow rate. Continue to keep for 0.5 hours until no liquid flows out. 2. If the product ...

How to control the emulsification temperature of the emulsifier?
A good cream product is not only reflected in the quality of raw materials, but also has a great influence on the emulsification process during production, such as the texture and stability of the product, and the temperature control during production will affect the cream product. Generally speaking, the emulsification temperature is determined by factors such as the melting point of the high melting point substance contained in the two phases, the type of emulsifier, the solubility of the o...
