Abstract

The invention discloses a dry granulation method for potassium sorbate granules in the field of compound granulation, comprising raw material preparation, raw material heating, raw material cooling, granulation agglomeration, extrusion granulation, surface drying and particle polishing process. The method above comprises the following steps: S1: raw material preparation: sorbic acid, potassium carbonate and ethanol are put into the reaction kettle to form potassium sorbate solution for standby use; S2: raw material is heated: S3:raw material is cooled ; S4: granule agglomeration: S5: extrusion granulation: the raw materials are put into the extrusion granulator to form particles; S6: surface drying: S7: particle polishing: through the drying method, the invention will dry the water inside the potassium sorbate granule , which can well control the internal moisture content. The prepared potassium sorbate granule is with good crystal model,in stable structure and free from the agglomeration .The production process is simple and suitable for large-scale use of the plant.

Description

technical field [0001] The invention relates to the technical field of compound granulation, in particular to a dry granulation method of potassium sorbate granules. Background technique [0002] Potassium sorbate is white to light yellow scale-like crystals, crystalline particles or crystalline powder, odorless or slightly odorous, it is easy to absorb moisture when exposed to the air for a long time, and is oxidized and decomposed to change color. Potassium sorbate is easily soluble in water, 67.6g / 100ml (20°C); 5% salt water, 47.5g / 100ml (room temperature); 25% sugar water, 51g / 100ml (room temperature). Soluble in propylene glycol, 5.8g / 100ml; ethanol, 0.3g / 100ml. The pH of 1% potassium sorbate aqueous solution is 7-8. Sorbic acid (potassium) can effectively inhibit the activity of mold, yeast and aerobic bacteria, and can also prevent the growth and reproduction of harmful microorganisms such as botulinum, staphylococcus and salmonella, but it is not effective for anae...
