Abstract
Description
Technical Field
[0001] This utility model relates to the field of food processing technology, specifically a heat exchange device for a baking oven. Background Technology
[0002] An oven is a device that uses hot air to bake and cook food; it is generally a closed or semi-closed structure. Ovens are also called baking ovens, baking pans, or grills. Those that use hot air in an open format are called barbecue ovens. The term "oven" can also be used broadly to refer to any device that uses hot gas for high-temperature processing. Traditional ovens use wood or coal for heating. Modern ovens are multifunctional, using either electric or natural gas heating. They come in single-layer, double-layer, and triple-layer models, with each layer independently controlled and capable of simultaneous use. They can also be used as single-layer ovens. Most modern ovens have an automatic temperature control system.
[0003] With the promotion and application of energy conservation and emission reduction, the energy consumption of equipment is required to be gradually reduced. Baking ovens are high-energy-consuming equipment. If the heat energy of the high-temperature gas emitted by the oven can be effectively recycled, energy consumption and operating costs will be effectively reduced. Therefore, a heat exchange device for baking ovens is proposed here. Utility Model Content
