Introduction
The tablet coating machine is an electromechanical facility used for sugar coating, organic thin film coating, dissoluble film coating, slow releasing, and controlled releasing coating of Chinese and Western medicine, tablets, pills, pellets, small pills, watered pills, dripping pills, granules, etc. It is efficient, energy-saving, safe and clean, and meets GMP requirements. As a new process of medicine production, it guarantees the quality and validity of drugs by coating drugs. It is widely used in scale production and mass production in pharmaceutical and food industries.
The tablet coating machine uses the programmable control system to control pills in the roller of the machine to make them carry out complex track movement continuously and repetitively. Hot air penetrates gaps in tablets, the sprayed medium on the surface of the tablet fully contacts hot air and is gradually dried, and exhaust gases are discharged from the bottom of the roller through the air duct after dust removal by the exhaust fan. Tablets processed by this machine forms a sturdy and smooth film.
Performance Characteristics
1. The constant pressure variable peristaltic pump spares the return pipe. The rotating radius of the roller changes at any time with pressure. The sprayed slurry and spraying volume are automatically balanced to stabilize atomizing effect, simplify spraying system, prevent block of spraying gun, and saves coating materials. In addition, the machine is easy to clean without dead corners.
2. The spraying gun of tablet coating machine specially designed and manufactured for coating has uniform atomization, large spraying surface and adjustable nozzle direction; The spraying gun cleaning mechanism can make the coating work continuous, coating time shortened, and saving coating materials at the same time.
3. The control system composed of PLC (programmable logic controller) human machine interface is reasonable in design and flexible in programming. It has stable and reliable operation and meets the GMP requirements. It can meet needs of various pharmaceutical processes.
4. Under the action of the streamlined deflector and the stirrer, uncoated tablet turns smoothly and exchanges frequently. The phenomena of uncoated tablets falling from a high place and collision are eliminated, fragment and edge breaking are prevented, and the yield is improved. Since the upper surface of the deflector is narrow, the attachment of coating materials to the surface is avoided, which saves coating materials and improves the quality of drugs.
5. Adjustment and control of slurry atomizing coverage: Imported spraying guns are selected, with excellent atomizing effect; adjust angle and flow rate of the nozzles and the fan adjustment button on it according to the amount of materials in the coating machine, which can not only realize easy atomizing coverage control and flexible process requirement control, but also avoid the influence of the one-size-fits-all operation of the machine and human error due to inadequate technical knowledge on atomizing effect, facilitating formulating position SOP, and can save coating materials and reduce costs.
