Abstract

The invention relates to a method for coating tablets with sugar, which uses the existing coating pan and coating spray gun equipment to coat the sugar on the tablets, and particularly comprises the step of coating a powder coating layer and a colored layer by using syrup and colored syrup. According to the brand-new method for coating the tablets with sugar provided by the invention, the existingcoating pan and coating spray gun equipment are adopted, so that programmed control of the tablet sugar coating process is realized, the effect difference of tablet sugar coating caused by manual slurry adding of an operator is avoided, and the uniformity of the tablet sugar coating is improved.

Description

technical field [0001] The invention relates to a method for coating tablets with sugar. Background technique [0002] Most of the tablets are coated with a layer of sugar called "sugar-coated tablets", which can make the tablet beautiful and can also cover up the bad smell of traditional Chinese medicine, so patients are willing to take it. Syrup is mainly used as the coating material. The sugar coating has a certain function of moisture-proof and air-isolation, which can cover up the bad smell of the drug, improve the appearance and be easy to swallow, and has little effect on the disintegration of the tablet. [0003] The existing sugar coating technology generally uses a non-porous coating machine and a perforated coating machine to add syrup into the coating pan by manual slurrying or reflux dripping for sugar coating. The manual grouting method has higher requirements on the operator, and the operation error is larger. The equipment used in the backflow dripping metho...
