Spray rate control is very important in aqueous film coating and if the spray rate varies during the coating process, several problems are encountered. The spray rate is controlled primarily through the use of a peristaltic pump. Peristaltic pumps are the simplest and easiest to clean. The spray rate ...

Film coating process Film coating plays a very important role and a number of problems in tablet coating are related to process setup. There are many variables that should be controlled in a process and we will understand how these variables are important to the film coating process. We will study the ...
