Atomizing closed coating machine capable of automatically controlling boiler temperature

Abstract

The invention discloses an atomizing closed coating machine capable of automatically controlling boiler temperature. The coating machine comprises a motor (1) and a coating boiler (2). The coating boiler (2) is driven by the motor (1) to rotate by a transmission device (8). The atomizing closed coating machine further comprises a controllable normal temperature hot air device, a liquid storage bucket (13), a spraying device and a programmable logic controller (PLC). The controllable normal temperature hot air device comprises a constant temperature cabinet (3) and a fan (4). An atomizing device comprises an atomizer (10) and a peristaltic pump (11). The atomizing closed coating machine has the advantages of adopting the full closed mode, ensuring sanitation and hygiene due to the fact that pills are not contacted with external air in the coating process, utilizing the PLC to strictly control boiler temperature, being capable of maintaining pills to work under rated temperature, utilizing the atomizer to transform coating solution into mist and enter a coating boiler to be evenly wrapped on the surface of the pills and being capable of well protecting pesticide effect of the pills.

Description

technical field [0001] The invention relates to a pharmaceutical equipment, in particular to a spray-enclosed coating machine whose temperature in a pot can be automatically controlled. Background technique [0002] In the production process of pharmaceutical solid preparations such as pills, in order to achieve the purposes of masking the smell of the pills, moisture-proof, light-proof, and controlling the release site and release speed of the pills during use, a coating treatment is required for the pills. Coat sugar or other film-forming materials on the outer surface of the pill, and dry it to form one or several layers of multi-functional protective layers of different thicknesses and different elasticity tightly adhered to the surface. This multi-functional protective layer It's called coating. [0003] At present, the equipment for coating the pills is called a coating machine. Most of the existing coating machines spray the coating solution on the drug during proces...

AI Technical Summary

Problems solved by technology

[0003] At present, the equipment for coating the pills is called a coating machine. Most of the existing coating machines spray the coating solution on the drug during processing, and then turn the coating. When the ground is in contact with the drug, the coating is very uneven, and it is difficult to achieve the effect of protecting the drug; moreover, the temperature in the coating pan is generally changing, which requires manual monitoring and control, so as to keep the temperature at the rated temperature, increasing the The amount of labor, and prone to errors, some unqualified coated pills
