Easy-to-clean fluid bed granulator and cleaning method thereof

Abstract

The invention discloses an easy-to-clean fluid bed granulator, which comprises a rack. A granulating tank is arranged on the rack and is provided with a base buffer hopper, a material container and adiffusion trapping chamber. A bag shaking cylinder and a lifting assembly are arranged on the outer wall of the upper end of the diffusion trapping chamber. The output shaft of the bag shaking cylinder is a hollow shaft. An inserting rod is arranged on a bag shaking frame. The lifting assembly is connected with the inserting rod through a rope. The inserting rod and the hollow shaft can be lockedand fixed through a locking device. A partition plate is arranged on the inner wall of the upper end of the diffusion trapping chamber. A spraying device is arranged in the granulating tank and comprises a plurality of first spraying heads and second spraying heads. The water inlet ends of the first spraying heads are arranged on the outer wall of the upper end of the diffusion trapping chamber, the water inlet ends of the second spraying heads are communicated with the exterior through a water pipe, and the material container is arranged on the rack in a hinged mode. The provided fluid bed granulator and cleaning method have the advantages that the tank does not need to be disassembled, the cleaning effect is better, and the cleaning is more convenient.

Description

technical field [0001] The invention belongs to the technical field of granulation equipment, in particular to an easy-to-clean boiling granulator and a cleaning method thereof. Background technique [0002] Boiling granulator is one of the equipment used in the solid preparation production process in pharmaceutical, chemical, food and other industries. The traditional fluidized granulator includes a frame and a granulation tank set on the frame. The granulation tank is connected to the base buffer bucket, the material container (for placing materials) and the diffusion and trapping chamber in sequence from bottom to top. During granulation, the base buffer bucket is provided with an air inlet and ventilated to the inside, so that the material is blown into the diffusion and collection chamber, and an atomization spray gun for adhesive atomization is installed in the diffusion and collection chamber. The material is allowed to come into contact with the binder to form solid...

AI Technical Summary

Problems solved by technology

[0003] At present, because the granulation tank of the traditional fluidized granulator is equipped with a number of catch bags (which can be used to prevent the material from being blown out), a number of shaking bag locking devices (used to fix the catch bag) and a number of shaking bags frame (for the installation and support of the capture bag), etc., which make its internal structure complex, and the various parts inside the tank block each other or because the parts are set too far in the corner, the cleaning is not clean or the cleaning is not good. If it is in place, it is difficult to clean the material on the surface of some unclean parts, and too much human intervention is required to disassemble and wipe the tank body. Not only the cleaning effect is not good, but also the cleaning steps are cumbersome and the cleaning time is long
