AI Technical Summary
Existing cellulase preparation drying equipment suffers from problems such as uncontrollable temperature, large humidity fluctuations, and lack of activity protection mechanisms, leading to enzyme protein denaturation and inactivation, agglomeration and clumping, and low activity retention rate.
Employing a temperature and humidity controlled chamber, a low-temperature fluidized bed structure, an activity protection module, and a data acquisition and feedback system, the uniform dispersion and high activity retention of cellulase preparations are achieved through precise temperature and humidity control, low-temperature inert gas protection, and enzyme activity protection.
It significantly improves the activity retention rate and product uniformity of cellulase preparations, ensuring the stability and reliability of industrial production.
