Description

Technical Field

[0001] The utility model relates to the technical field of preheating feeding of a firing machine, in particular to a preheating component of a firing machine. Background Art

[0002] The baking machine is a kind of equipment used for food processing, mainly used for the pretreatment and processing of rice crackers and cereal puffed foods. It uses high-temperature rapid heating to quickly evaporate the water inside the food raw materials, thereby achieving the puffing effect, making the food volume larger, the texture lighter, and the taste crisper. The core function of the baking machine is to achieve uniform heating and puffing of food raw materials by controlling the heating temperature and time.

[0003] However, in actual use, when the baking machine heats the food embryo, the food embryo located at the edge may not be heated properly, which will cause the biscuits to have a poor puffing effect. Therefore, a preheating component of the baking machine is proposed to preheat the food embryo entering the baking machine in advance, so as to avoid the food embryo located at the edge from being heated properly, thereby improving the puffing effect of the biscuits. Utility Model Content

[0006] The air outlet holes are provided on both sides of the shell;

[0007] Wherein, an air guide plate is fixedly installed on the outer side of the shell above the air outlet.

[0008] When using a preheating component of a burning machine in the technical solution, the resistance heater is fixedly installed on the inner side of the cover body through an insulating ring, and a mesh frame is fixedly installed on the inner side of the cover body above the resistance heater. At this time, the cover body can be fixedly installed on the top of the shell body by installing screws, and the shell body can be fixedly installed on the middle section of the biscuit embryo conveying line by nut columns. When the biscuit embryo is conveyed, the resistance heater and the fan body can be started to generate high-temperature air in the shell body, and under the action of the fan body, the high-temperature air in the shell body can be discharged through the air outlet, so that under the action of the air guide plate, the high-temperature air can be conveyed to the biscuit embryo at the edge, thereby realizing preheating of the biscuit embryo at the edge.

[0009] Preferably, nut columns are fixedly installed in a rectangular array on the lower surface of the shell.

[0010] Nut columns are fixedly installed in a rectangular array on the lower surface of the shell, so that when in use, the shell is fixedly installed in the middle section of the biscuit embryo conveying line through the nut columns.

[0011] Preferably, the upper surface of the cover body is opened with a hole and the fan body is embedded and installed, the front end of the cover body is opened with a hole and a heat insulation ring is embedded and installed, and the front inner side of the cover body is fixedly installed with a mesh frame.

[0012] By opening a hole on the upper surface of the cover and embedding and installing a fan body, air can be injected into the shell through the fan body, and the gas in the shell can be heated under the action of the resistance heater.

[0013] Preferably, the mesh frame is located above the resistance heater and is not in contact with the resistance heater.

[0014] By fixing the mesh frame above the resistance heater and not contacting the resistance heater, the air injected into the fan body can pass through the mesh frame to evenly pass through the resistance heater, thereby reducing the temperature difference of the air discharged from the shell.

[0015] Preferably, the front end of the resistance heater passes through the thermal insulation ring, and the resistance heater does not contact the shell.

[0016] The front end of the resistance heater passes through the heat insulating ring and the resistance heater does not contact the shell, so that the high temperature generated by the resistance heater can minimize the adverse effect on the shell.

[0017] Preferably, the air guide plate forms an angle of forty-five degrees with the outer walls on both sides of the shell.

[0018] By arranging the air guide plate at an angle of 45 degrees to the outer walls on both sides of the shell, the air discharged from the air outlet can be guided by the air guide plate.
