Description

Technical Field

[0001] The utility model relates to a fluidized granulator, which belongs to the technical field of food and drug manufacturing, and particularly relates to a fluidized granulator for manufacturing food and drug granules. Background Art

[0002] Fluidized granulators are mainly used for pharmaceutical granulation and coating. Powdery materials are put into a closed container of a hopper. Due to the action of hot air flow, the powder is suspended and circulated in a fluidized state to achieve uniform mixing. At the same time, atomized binder is sprayed to wet the powder in the container, causing the powder to coagulate into loose small particles. During granulation, due to the efficient drying of the hot air flow, water continuously evaporates and the powder continuously solidifies, forming ideal and uniform multi-porous spherical particles.

[0003] The existing fluidized granulator, such as the Chinese patent with the publication number CN216756338U, uses an induced draft fan to generate negative pressure in the granulation chamber, introduce hot air into the granulation chamber, and granulate the powder therein. At the same time, a circuitous air flow channel formed by multiple first plates and second plates is arranged in the exhaust duct, and the air carrying powder particles is discharged along the circuitous channel. However, the following problems occur during the discharge process: 1. A large amount of dust is carried in the gas discharged into the air, causing environmental pollution; 2. During the process of removing dust, some powder particles remain in the first or second plate body, causing problems such as channel blockage and inconvenient cleaning; 3. A large amount of powder particles cannot be recovered, resulting in serious waste of materials.

[0004] In view of the problems existing in the above-mentioned prior art, it is very necessary to research and design a new type of fluidized granulator to overcome the problems existing in the prior art. Summary of the Invention
