Description
Technical Field
[0001] This utility model relates to the technical field of empty capsule processing equipment, and in particular to the technical field of efficient gelatin capsule drying devices. Background Technology
[0002] Gelatin capsules consist of a cap and a body, made from pharmaceutical-grade gelatin and excipients. They are mainly used to contain solid and liquid medications, such as homemade powders, health products, and pharmaceuticals. This solves the problem of unpalatable taste and difficulty in consumption, truly making good medicine palatable. During the processing of empty capsules, drying is required. In the traditional empty capsule drying process, the empty capsules are stacked together and dried by hot air. However, because the hot air can only directly dry the outer capsules, the inner stacked capsules dry slowly and not thoroughly, lacking uniform drying. Summary of the Invention
[0003] The purpose of this invention is to solve the problems in the prior art and propose a highly efficient gelatin capsule drying device that can dry gelatin capsules from the bottom and simultaneously dry gelatin capsules near the stirring paddle with hot air, achieving multi-angle and all-round drying, resulting in uniform drying effect and high drying efficiency.

The rotary motor is located at the top center of the heat-insulating drying cylinder, and the stirring shaft is installed at the bottom of the rotary motor. The stirring shaft vertically penetrates the heat-insulating drying cylinder along its axis. An air guide channel with an open bottom is axially arranged inside the stirring shaft, and the outer side of the stirring shaft is uniformly... The drying cylinder is surrounded by several stirring paddles, each with a number of heat-conducting air holes evenly distributed on it. These air holes are connected to an air guiding channel. An air intake pump is installed at the bottom of the drying cylinder, with an electric heater installed at the air intake end. The exhaust end of the air intake pump is connected to the air guiding channel. Several hot air nozzles are evenly distributed on the bottom inner side of the drying cylinder, and these nozzles are connected to the exhaust end of the air intake pump. An open-type feed hopper is installed at the top of the drying cylinder, and a splash guard is detachably installed at the top opening of the open-type feed hopper.
[0005] Preferably, the heat-insulating drying cylinder is a vertical cylindrical shape, and the outer surface of the heat-insulating drying cylinder is uniformly covered with a layer of heat-insulating cotton.
[0006] Preferably, there are multiple stirring paddles, which are evenly distributed in a spiral shape around the outer side of the stirring shaft. The stirring paddles are made of heat-conducting metal and have an exhaust channel that connects the air guide channel and the heat-conducting air hole inside.
[0007] Preferably, the heat-conducting vents are vertically and evenly distributed at the bottom of the heat-insulating drying cylinder, and an isolation mesh plate is provided at the top opening of the heat-conducting vents.
[0008] Preferably, the electric heater is a constant temperature electric heater, the air inlet end of the air pump is a heat-conducting metal pipe, and the electric heater is fixedly attached to the heat-conducting metal pipe.
[0009] Preferably, the bottom side of the heat-insulating drying cylinder is provided with a discharge channel, and a discharge valve is provided at the outer end of the discharge channel.
[0010] The beneficial effects of this utility model are as follows: This utility model combines a heat-insulating drying cylinder, a rotary motor, a stirring shaft, an air guide channel, a stirring paddle, heat-conducting air holes, an air inlet pump, an electric heater, hot air nozzles, an open-type feed hopper, and a splash guard plate. After experimental optimization, it can dry gelatin capsules from the bottom through evenly distributed hot air nozzles at the bottom of the heat-insulating drying cylinder. At the same time, the gelatin capsules near the stirring paddle are dried by hot air during the stirring process through the heat-conducting air holes connected to it. This multi-angle, all-round drying results in uniform drying and high drying efficiency.
