Our general tablet coater literature describes the coating capability of a tablet size of up to 10 mm. However, this refers to a diameter rather than a capsule style design in length. The Mini Coater Drier is incredibly versatile and really the limiting factor is generally a weight issue as opposed to size. It’s important to consider weight/batch size to ensure a good coating motion within the coating apparatus. Please see the image below from a previous trial, where we have coated elongated capsules of 25 mm in length. We were using 15-20 capsules per batch.
At the other end of the scale we talk about the smallest size that can normally be coated as something >600 microns. However we have had one customer who has successfully coated particles with a size of 350 microns.
Please contact us if you need to coat large capsules or very small particles in the Mini Coater Drier. Our team of equipment experts will be able to provide you with valuable insight and advise on whether the Mini Coater Drier will suit your needs.
