1, decompression and desolventization require strict inspection and maintenance of the decompression kettle to ensure its sealing and decompression effect and reduce safety risks. Operators need to wear protective equipment, including explosion-proof glasses, gloves and explosion-proof clothing, to ensure personal safety.

2. For positive pressure desolventization, attention should be paid to selecting suitable desolventizing gases, such as nitrogen and inert gases, to ensure the desolventizing effect, and at the same time, to prevent the desolventizing gases from oxidizing the mixture, resulting in the decline of product quality.
