🧠 What an Auto Coater Does
An auto coater is a machine used especially in pharmaceutical, food, and confectionery industries to apply coatings (film, sugar, enteric, aqueous, organic) on tablets, pills, pellets, or candies. It automates the spraying and drying process to achieve a uniform, smooth, and controlled film layer.
How it works (in brief):
The product batch is placed in the rotating coating pan or drum.
Spray guns/nozzles apply the coating liquid evenly as the pan rotates.
Hot, filtered air flows through to dry and fix the coating quickly.
The process is usually managed by PLC controls for precision.
