Coating pans are used to form an aqueous or organic film around any kind of pellets and tablets or micro granules. These pans are also widely used to sugar-coat tablets. A coating pan is an essential requiremet in pharmaceutical applications. Different coating techniques are applied in pharmaceutical industry.
How Does a Coating Pan Works ?
Pellets/Tablets are continuously fed into a coating drum at a controlled rate. A high volume of process air heats the tablets at the time of entering and moving in the drum. Coating solution is applied through a series of spray guns as the product moves down the length of the coating drum. The tablets are homogeneously mixed for a uniform coating/weight gain. Shallow bed depth of the pan allows the tablet/pellets to pass through the spraying zone and finally discharged from the exhaust end of the coating drum and transported through a conveyor belt for collection, storage, inspection and packaging. These machines ensure consistent exterior coating.
Salient features of Coating Pan are as follows:
- Usually, temperature can be controlled with the help of temperature controller.
- Compact hot air blower with inlet air damping arrangement, is generally there in different coating pans.
- Mounting facility is available for easy change from coating pan to polishing pan.
- Coating pans do not require any foundation and are able to install on pre leveled floor.
- Flameproof type of construction is optional.
