The invention relates to the field of preparation of traditional Chinese medicine granules, in particular to a method for preventing wall sticking in preparation of traditional Chinese medicine granules by spray drying. This method takes advantage of the characteristics of the network formed by the ripening of glutinous rice flour, and fixes most of the soluble components in the concentrated Chinese medicine, such as sugars, in the network structure, thereby reducing the adhesion. After one step, agar colloid is used as a spacer , the colloid forms a film on the surface of the fine particles of the Chinese medicine concentrate and the grain powder that adsorbs the drug, and the agar colloid condenses into a jelly-like solid isolation film in the first-stage drying tower, and is dried at high temperature in the second-stage drying tower. The material is completely dried to form a solid film, and uniformly dispersed Chinese medicine granules are obtained. It not only effectively prevents the adhesion to the inner wall of the spray dryer drying tower, but also effectively isolates the bonding between the granules of the granule. It overcomes the defect that the granules of traditional Chinese medicine granules are easy to stick to the wall in the preparation of spray-drying.
