Baking tunnel oven

Abstract

The invention discloses a baking tunnel oven. The baking tunnel oven comprises an oven body, a conveying mechanism and a heating device; an oven inlet is formed at one end of the oven body, and an oven outlet is formed at the other end of the oven body; the conveying mechanism is mounted in the oven body, two ends of the conveying mechanism penetrate through the oven inlet and the oven outlet respectively, and the conveying mechanism is used for conveying to-be-baked food; the heating device is mounted in the oven body; the conveying mechanism comprises a correcting assembly, a tensioning assembly, a high-temperature-resistant conveyer belt, a driving roller, a driven roller and a drive unit; the correcting assembly is used for preventing the high-temperature-resistant conveyer belt from deviating, and the tensioning assembly is used for adjusting degree of tightness of the high-temperature-resistant conveyer belt; one end of the high-temperature-resistant conveyer belt bypasses the driving roller, and the other end of the high-temperature-resistant conveyer belt bypasses the driven roller to form closed ring; and the drive unit drives the driving roller to rotate, and therefore, the high-temperature-resistant conveyer belt is driven to operate. The tunnel oven occupies small space, the equipment is simple and convenient to maintain, and meanwhile, production cost of food is reduced; and the baking temperature of the baking tunnel oven is 300 DEG C or lower generally.

Description

technical field [0001] The invention relates to the field of food machinery, in particular to a baking tunnel oven. Background technique [0002] The baking tunnel oven is mainly used for baking food, such as bread, cake, biscuit and so on. The baking tunnel furnace is equipped with a high-temperature conveyor belt, which is mainly used to transport the food to be baked. In the prior art, the high-temperature conveyor belt in the baking tunnel furnace generally adopts metal materials, such as metal chain plate, metal steel belt, metal mesh belt and the like. The metal conveyor belt has excellent high temperature resistance and high tensile strength, so it has certain advantages when used in baking tunnel furnaces. However, the metal conveyor belt also has the following disadvantages: it is heavy, and it is inconvenient to replace and maintain; before the food is baked, the conveyor belt needs to be preheated, and the metal conveyor belt takes a long time to section, the m...

AI Technical Summary

Problems solved by technology

However, the metal conveyor belt also has the following disadvantages: it is heavy, and it is inconvenient to replace and maintain; before the food is baked, the conveyor belt needs to be preheated, and the metal conveyor belt takes a long time to section, the metal conveyor belt exposed outside the tunnel furnace will transfer more heat to the air, resulting in partial loss of heat; in addition, because the transmission system of the metal conveyor belt is relatively complicated, in order to make full use of the transmission system, the metal The conveyor belt is generally set relatively long, so the tunnel furnace using the metal conveyor belt is generally relatively large in size

Therefore, when the temperature required for baking food is not high, the baking tunnel furnace with metal conveyor belt is used for baking, the production cost is high, the tunnel furnace takes up a large space, and the equipment maintenance is inconvenient
