Coating machineAll of them are refined using imported stainless steel, and the main door components and their built-in parts are formed using a stamping mold forming system. The main panel is streamlined through "light pollution treatment", and the manufacturing process is based on the "Enterprise Product Execution Standard" and the equipment manufacturing standards in accordance with the "GMP Implementation Guidelines for Pharmaceutical Enterprises". It is easy to clean, aesthetically pleasing, and practical, and is indeed a standardized equipment in the "GMP" acceptance of pharmaceutical factories.
Working principle of coating machine:
Under the action of streamlined guide plates in a clean and sealed rotating drum, Su Rui continuously moves in complex trajectories. During the movement, the coating medium is automatically sprayed according to the process flow and reasonable process parameters, while hot air is supplied under negative pressure. The hot air is discharged from the bottom of the Su Rui layer through the Su Rui, allowing the coating medium sprayed on the surface of the Su Rui to dry quickly and uniformly, forming a strong and smooth surface film.
We are purchasingCoating machineWhen it comes to this, in addition to what we have mentioned above, we should also look at the 7 basic parameters.
1. The position of the spray gun, that is, the position of the atomizing spray gun inside the coating drum, generally has two modes: the spray gun faces the lower direction inside the drum or the spray gun faces a certain position on the inner wall of the drum. Generally speaking, this mode is very important for the quality of the final coating of Zui, while the domestic mode mainly focuses on the orientation of the spray gun facing the lower part of the cylinder body.
2. Spray speed, namely atomization amount, is the total amount of coating liquid (suspension) sprayed per unit time.
3. The atomization pressure includes two concepts, namely the pressure of the mist generated by the atomization gas at the nozzle of the spray gun and the suspension, and the pressure of the atomization gas itself.
4. The inlet temperature refers to the temperature of the hot air inside the inlet drum used for drying coated tablets.
5. The total inlet air volume, which is the air volume used for drying and penetrating the tablet bed in the inlet drum, is usually adjusted slightly higher than the inlet air volume to create a slight negative pressure inside the coating drum, allowing the coating solution to smoothly enter the tablet bed.
6. The internal pressure of the coating cylinder, the pressure difference between the coating cylinder and the room, and the insufficient pressure difference causes the coating solution to be unable to be sucked into the tablet bed, and adhere to the surface of the tablet bed, the inlet, the inner wall of the cylinder, or the spray system; Excessive pressure difference can introduce excess coating liquid into the tablet bed.
7. The speed of the coating roller is theoretically believed to be constant based on experience, but the exact method remains to be explored.
Coating machineIt is a mechanical and electrical integrated equipment that uses both traditional Chinese and Western medicine, tablets, pills, micro pills, small pills, water pills, drop pills, granules, and other forms of sugar coating, organic film coating, water-soluble film coating, and gentle, controlled release coating. It is energy-saving, safe, clean, and meets GMP requirements. It is a new technology in domestic drug production that ensures drug quality and shelf life through drug coating.
