Description

Technical Field

[0002] Potassium sorbate is the potassium salt of sorbic acid. It is white to light yellow scaly crystals, crystal particles or crystal powder. It is odorless or slightly odorous. It is easy to absorb moisture and change color due to oxidation and decomposition when exposed to air for a long time. It is easily soluble in water, propylene glycol and ethanol. It is often used as a preservative. It destroys many enzyme systems by combining with the sulfhydryl groups of microbial enzyme systems. Its toxicity is much lower than other preservatives and it is widely used.

[0003] During the preparation of potassium sorbate, it needs to be dried to remove the water and granulate. The general drying equipment continuously stirs the mixed liquid through a stirring structure and dries the liquid in the mixed liquid by high temperature heating to achieve the separation of potassium sorbate. However, this drying method takes a long time to process large quantities of potassium sorbate mixed liquid, and it is not easy to improve production efficiency. Summary of the invention
