Baking ovens release moisture, volatile compounds, or trapped gases from coating on finished products. In powder coating, the baking process heats the powder to its melting point to adhere it to a metal surface. Baking ovens are thermal processing units that combine curing and drying. The cure painted parts by speeding up the drying process and by removing moisture from the air to leave a flawless finish. The food and packaged goods industries use batch and conveyor industrial baking equipment to increase the speed of food production and to maintain quality control.
