A full surge type granulation coating host

Abstract

The invention relates to the technical field of fluidized bed coating machines, and discloses a full-flow granulation and coating main engine, which includes a wind guide, and a bowl is movably placed on the top of the wind guide, and the bowl The bottom of the bowl is provided with a circular hole, and the diameter of the hole is the same as the diameter of the inner cavity of the wind guider. The two ends of the top of the bowl are symmetrically equipped with spring sheets, and the bowl is fixed with rollers through the spring sheets. The full surge type granulating and coating main engine, through the movable placement of a bowl on the top of the wind guide, the setting of the bowl can prevent the raw materials from entering the triangular area between the fluidization chamber and the bottom of the wind guide on the one hand, so that The qualification rate of raw materials can be guaranteed. On the other hand, the shape of the bowl is set so that the raw materials pass through the acceleration wall and the rising wall in sequence when they slide down, and then go through the fluidization of the hot air source, so that the rising distance of the raw materials is higher, which is different from the package. The longer coating contact time further improves the coating quality.

Description

technical field [0001] The invention relates to the technical field of a fluidized bed coating machine, in particular to a full-flow granulation coating machine. Background technique [0002] Coating machine is a kind of electromechanical integration equipment for organic film coating of tablets, pills, candies, etc. [0003] see figure 1 , the working process of the existing coating machine is to put the raw material 6 into the bottom of the bottom spray raw material container 1, and spray the hot air source and coating paint through the spray nozzle 4 installed in the inner guide chamber 3 of the wind guide 2, so that the raw material 6 is in the flow The inside of the chemical chamber 5 flips up and down, so that the coating material is evenly sprayed on the outer surface of the raw material 6. After the process is completed, the processed raw material 6 can be unloaded. [0004] It can be seen that the problem existing in the existing fluidized bed coating machine is t...

AI Technical Summary

Problems solved by technology

[0005] The present invention provides a full surge type granulation and coating main engine, which has the advantages of increasing the bowl so that the raw materials do not enter the triangular area, the raw material processing quality is good, and the bowl can be lifted to facilitate unloading, which solves the existing flow problem. The triangular area at the bottom of the fluidization chamber and the air guide of the chemical bed coating machine is deep and the flow rate of the airflow is slow, so it is easy to cause the accumulation and blockage of raw materials, resulting in the problem of low processing pass rate of raw materials
