Coating of potato chips or fried potatoes is and will remain a popular processing step. The production of coated products makes special demands of the frying process. The coating with batter, the preparation of the coating, and an efficient and even application of the coating, as well as an extra fryer with integrated oil-filter system, together form a complete coating system.
Coating is applied for various purposes. Various herbs and spices may be added to the batter, allowing different flavours to be applied to potato chips, wedges or slices. Another reason to apply coating may be to make potato chips more crispy. Thanks to an almost invisible layer of starch, a more crispy crust will appear, allowing the potato chips to be crispy for longer and retain their heat. Potato chips produced in this way offer great advantages for drive-in restaurants and fast-food chains.
The batter is prepared with powder and water. The Tomanus coating preparation system is a dispensing and weighing system that prepares the batter with great precision and keeps it available in a cool condition in measured batches required by the production process.
Multiple tanks ensure ripening and setting and, if necessary, redispensing of the batter. The temperature and viscosity are constantly measured and optimised; in addition, lump formation is avoided. Hygiene is an important aspect for coating and the realisation of a good end product; the whole Tomanus preparation system has been geared to this. The coating line is easy to clean and has been equipped with various hygienic provisions, including different valves.
