Problems solved by technology
During the coating process, different drugs require different coating wind speeds and air volumes due to different particle sizes and densities. The traditional method is to keep the position of the coating tube unchanged and adjust the spray gun at the bottom of the coating tube according to different materials. The air flow rate and the replacement of the gas distribution plate can be realized, but because the position of the coating cylinder is fixed and not adjustable, the coating effect is not very ideal

The invention discloses an adjustable fluidized bed coating cylinder structure is arranged on a device cylinder. The adjustable fluidized bed coating cylinder structure comprises a coating cylinder arranged inside the device cylinder and adjustable in position, a connecting plate welded on the outer side wall of the coating cylinder, a polytetrafluoroethylene gasket fixed to the side face of the connecting plate through multiple set screws, a welding block welded to the side wall of the device cylinder and provided with a vertical long round hole, a cover plate covering the outer side face of the welding block, a connecting stud sequentially penetrating through the cover plate, the long round hole and the polytetrafluoroethylene gasket and then screwed into the connecting plate, a nut screw-connected to the top of the connecting stud and provided with a round groove and a spring arranged on the connecting stud in a sleeving mode and arranged in the round groove, wherein one end of the spring abuts against the cover plate, and the other end of the spring abuts against the nut. The coating cylinder is adjustable in position.
Description
technical field [0001] The invention relates to the coating field of fluidized bed granules, pellets and the like. Background technique [0002] In solid preparations, many drugs are coated to change drug release characteristics, such as sustained and controlled release, enteric coating, colon localization, pulse release, etc., or to achieve taste masking, moisture resistance, stability improvement, and appearance improvement. Due to the high drying efficiency, the fluidized bed coating equipment can realize the functional coating of pellets, granules, crystals, powders, etc., and achieve ideal reproducibility. During the coating process, different drugs require different coating wind speeds and air volumes due to different particle sizes and densities. The traditional method is to keep the position of the coating tube unchanged and adjust the spray gun at the bottom of the coating tube according to different materials. The air outlet rate and the replacement of the gas dis...
