Abstract
A spray coating machine and process accommodates coating pans of various sizes and simplifies cleaning after particulate material in the pan is coated. A selected pan is supported on a trolley carried by a wheeled cart. After the cart is positioned adjacent the coating machine, the trolley and pan are extended into the machine, and then the pan lifted for support by a rotatable drive shaft and castors. The trolley is then removed from the machine, and the door is closed so that the coating process can commence. When coating is complete, the door is opened, and the trolley extended into the machine under the pan and raised for removal of the castors. Then, the trolley and pan are withdrawn from the machine. The trolley does not need cleaning after spraying, since the trolley is outside the machine during spraying of the coating solution.
