Optimized Cereal Production
Fluoropolymers have been used as nonstick coatings in the food industry for a long time. It is this technology that allows economic production methods to be used for special applications.
In this specific application, cereal is coated with chocolate powder and then conveyed to the drying drum. Infrared radiators in the drum make the chocolate melt, allowing it to coat the cereal. The drum is tilted and rotated to feed the cereal through the drum to the ischarge and dry it along the way.
The melted chocolate tends to stick to the sides of the drying drum. The rotation of the drum, necessary for gentle stirring of the cereal, would cause the grains to stick to the drum. Then when the drum turns, the cereal would fall from above onto the infrared radiators and burn. The whole batch would have to be discarded.
The Impreglon coating solution provides an effective nonstick surface that prevents the chocolate coated cereal from sticking to the sides of the drum and falling onto the infrared radiators.
Excellent nonstick properties and the durability of the coating – approved of course for contact with food products – make the manufacturing process an economic one.
