Heat exchanger for food baking and heat exchange and heat dissipation integrated preheating baking equipment

Abstract

The invention discloses a heat exchanger for food baking. The heat exchanger for food baking comprises a top plate, a baseplate, a side plate, and a heat exchange separation plate arranged between the top plate and the baseplate; the heat exchange separation plate is fixed on the side plate, and divides a space between the top plate and the baseplate into multiple medium layers; and the heat exchange separation plate is manufactured by metal foils or metal sheets. The invention further discloses heat exchange and heat dissipation integrated preheating baking equipment; the equipment comprises a baking box body; a microhole air distributor is arranged at the lower part of the internal space of the baking box body, and is connected with a refrigerant outlet; a heating medium inlet is communicated with the upper part of the internal space of the baking box body through a guide pipe; an air blower is arranged in a refrigerant inlet; and an induced draft fan is arranged in a heating medium outlet. The whole heat exchange system occupies no additional space, fully uses a shell structure, and becomes chassis heating equipment of baking equipment, thermal insulation equipment at the lower part of the baking equipment and preheater equipment for recovering heat energy by waste gas.

Description

technical field [0001] The invention relates to a food baking equipment, in particular to a heat exchanger for food baking and an integrated heat exchange and heat dissipation preheating baking equipment. Background technique [0002] At present, the existing food processing and baking equipment can use the heat generated by the burner to process food. In order to make full use of the combustion heat and reduce heat loss, it is necessary to add a heat exchanger as a fresh air preheater. The preheaters of the temperature equipment are all external type. The exhaust gas produced by combustion preheats the blown fresh air, so that the heat in the exhaust gas is recovered to the fresh air for further use by the equipment. Except for the heat energy generated by the heat source inside this baking equipment, the rest of the structure is a heat dissipation structure, which cannot provide additional heat energy; the preheater is a traditional type heat exchanger, which is arranged ...

AI Technical Summary

Problems solved by technology

Except for the heat energy generated by the heat source inside this baking equipment, the rest of the structure is a heat dissipation structure, which cannot provide additional heat energy; the preheater is a traditional type heat exchanger, which is arranged separately from the baking equipment, occupying external space, and the heat loss of the pipeline is huge , low efficiency; the air input system is separated from the baking equipment, in addition to the problem of high-temperature airtightness, it is inconsistent with the heat flow field in the original system, which can lead to insufficient combustion, thereby wasting energy
