US 10,016,734 B2 · Method of producing potassium sorbate particles

Abstract

The present invention discloses a method of producing potassium sorbate particles, comprising the steps of: (1) preparing a potassium sorbate solution; (2) spray drying; (3) spray forming; (4) indirectly drying with steam on a vibration fluidized bed; and (5) swing-type sifting; in step (3), a binder is obtained by spray drying after adding sorbitol to the potassium sorbate solution prepared in step (1), and the binder is mixed with the potassium sorbate powder obtained by spray drying in step (2) to undergo the spray forming process; based on weight ratio, the weight ratio of the sorbitol required to prepare the binder to the potassium sorbate solution required to prepare the binder is 0.05-0.1%:1. The beneficial effects of the present invention are: an appropriate binding effect of the powder particles, a good breaking effect and a good spheronization effect of the powder particles, and uniformity of granulation.
