The Caleva small tablet and pellet coater is well known for the coating and drying of very small batches of pellets and tablets. It is the only commercially available equipment for this task. The Mini Coater Drier will coat from a single tablet or a few grams of pharmaceutical (or related) pellets. The process was originally developed for pharmaceutical pellet applications, but is also suitable for other applications (such as catalysts or ceramics) where small batches of small items need to be coated evenly and effectively.
It has been known for a long time that larger capsules containing pellets with active pharmaceutical materials can be effectively coated. Until now, the coating of small batches of very small pellets (size 9 or size M) has been a difficult, labour insensitive and time consuming process. Recent trials with the Caleva tablet and pellet coater have clearly demonstrated that very small batches of these very small (size 9 and size M capsules) can effectively be coated with this apparatus. The photographs on this page show the results from the very first preliminary trials and the effectiveness of this process demonstrated how easy and robust the coating process is. These small capsules were coated without any issues.
A great example of the MCD coating small capsules
If you would like to read a great example of the MCD coating small capsules, then take a look at this article. It comes from the University of South Australia who have used the MCD to help reintroduce endangered native Australian animals to their natural habitat.
