Processing Flow of Potassium Sorbate
Raw Material Preparation: The primary raw materials include sorbic acid and potassium hydroxide or potassium carbonate.
Neutralization: Sorbic acid is mixed with a potassium hydroxide or potassium carbonate solution to neutralize it. This reaction forms potassium sorbate and water.
Crystallization: The solution is cooled to promote crystallization of potassium sorbate. This process may involve evaporating excess water to concentrate the solution.
Filtration: The crystallized potassium sorbate is filtered to separate it from the remaining solution.
Drying: The filtered potassium sorbate is then dried to remove moisture, often using a spray dryer or vacuum dryer to achieve the desired moisture content.
Milling: The dried potassium sorbate may be milled to obtain the desired particle size, depending on its intended use.
Quality Control: Samples are taken for quality control testing to ensure the product meets specifications.
Packaging: The final product is packaged in suitable containers to protect it from moisture and contamination.
Storage: The packaged potassium sorbate is stored in a cool, dry place until it is ready for distribution.
This flow may vary based on specific production methods or equipment used by different manufacturers.
