Problems solved by technology

However, the conventional coating technology has the disadvantages of relatively low drying capacity, long coating time, and easy adhesion of the coating between particles. Long-term friction will also cause damage to the dropping pills, so the coating yield is relatively low.

Abstract

The invention belongs to the field of thin film coating agents and provides a fluidized coating method for flavoring essence micropills for tobacco. A coating solution comprises the following components and materials in parts by weight: 20-40 parts of framework material, 800-1000 parts of dispersant and 2-3 parts of auxiliaries; and the preparation method comprises the following steps: firstly dissolving the framework material in the dispersant, then adding the auxiliaries, uniformly stirring, milling by a colloid mill for 2-4 times, filtering and then getting the coating solution for later use. According to the fluidized coating method provided by the invention, the drying capacity of a coating can be effectively upgraded, the adhesion problem among particles of the flavoring essence micropills can be overcome, and the working efficiency of a coating process can be further improved.

Description

technical field [0001] The invention belongs to the field of film coating agents, and in particular relates to a method for fluidized coating of tobacco essence pellets. Background technique [0002] In recent years, dripping pill preparations have been widely used in many industries such as medicine, health food, cosmetics, and tobacco. Since the content of the drop pill preparation is a liquid substance, damage to the outer wall material will cause the leakage of the content and affect the use. Therefore, it is necessary to use coating technology to make the surface layer have better strength, moisture resistance, wear resistance and other properties. However, the conventional coating technology has the disadvantages of relatively low drying capacity, long coating time, and easy adhesion of the coating between particles. Long-term friction will also cause damage to the dropping pills, so the coating yield is relatively low. Contents of the invention [0003] The purpose...
