Processing chocolate, filling candies, pre-browning instant meals or heating surfaces of foods: exact temperatures that avoid overheating of the food are required in the food processing industry.
Infrared emitters transmit heat without contact and only as long as necessary.
Without preheating, and using energy efficiently, heat is delivered exactly when it is needed.
Moreover, IR emitters react very quickly and can therefore be well controlled - an important precondition for the quality of food.
Food must be packed, in cans, foil or paper and cardboard - food safe and leak proof. No harmful substances from outside, no fats from inside should penetrate the packaging. Infrared heat dries the necessary special coatings.
