Tablet Coating Machine


Film Coating: Coat with thin protection layer on the tablets. (Aqueous or organic solvent are applicable)
Enteric Coating: Coat with a uniform protection layer on the tablets to protect against the gastric acidity (PH2)
Sugar Coating: Coat with sugar protection layers on the tablets.

Sugar Coating System, Super Coater, Tablet Coater

Principles of the Super Coater

  1. Film / Enteric Coating:
    Pump the solution to a spray gun then spray onto the tablets in the tumbilng pan and continuous dry by heated air to form a uniform and a thin layer on the tablets surface.
  2. Sugar Coating:
    The syrup spray to the tablets by a metring pump, then through the repeated process of tumbling, cooling and drying to form a thick sugar layer in order to protect the tablet.

Optional devices are available

  1. Explosion proof system (Organic solvent is applicable)
  2. WIP or CIP system
  3. Touch Screen Interface control system
  4. Temperature recorder
  5. Dehumidifier device
  6. Dust collector system (Wet or Dry types)
  7. High accuracy air volume / pressure measuring device
  8. Weighing system (To observe the changing of the solution)
  9. Preparation tank


1. Comply with regulations of cGMP, PIC/S GMP, FDA
2. Coating pan punch hole design: High drying efficiency
3. Stable control of air inlet/outlet temperature, humidity, flow, pressure: Minimum waste of coating material.
4. Aqueous or organic solvent are applicable (Ex-Proof type)
5. Well uniformity coating for functional coating: including control release coating, film coating, micro tablet coating
6. High yield rate: Un-even coloring, broken, or twinning tablets can be less than 0.2%.
7. Stable control of critical parameters
  a. temperature control: Setting Value ±2℃ (With optional air damper: ±1℃)
  b. Humidity control: Air inlet moisture can be controlled as 9g/Kg ±1g/Kg. (Chilled water: inlet 7℃, return 12℃)
  c. Inlet air flow can be controlled within ±5% in 30~100%.
  d. Differential pressure of coating pan can be set and controlled with accuracy ±5%
  e. coating spray rate can be set and controlled with accuracy ±5%
8. Use of Schlick spray gun, better atomization(optional)
9. Use of Donaldson dry dust collector: for environment protection(optional)
10. Air handling unit consists of pre filter, medium filter, and HEPA filter to assure processing air cleanliness.
11. A cantilever design of the spray guns rack is easy for operation (A slide track design is for the large model)
12. Automatic discharge device: complete discharge within 10 mins
