[0001] The utility model relates to the technical field of food production equipment, in particular to a hot air circulation baking furnace for mooncake production. Background Art

[0002] The production of mooncakes has relatively high requirements for temperature control, and the cake blanks fed into the baking furnace need to be evenly heated in the baking furnace to produce mooncakes with alluring color, aroma and taste. Currently, hot air circulation baking furnaces are commonly used for baking mooncakes. The hot air circulation baking furnace is durable, easy to operate, and its internal heat circulation characteristics make the baked objects evenly heated, which is suitable for baking mooncakes. However, in existing hot air circulation baking machines, such as the hot air circulation baking furnace for mooncake production described in CN212678192U, the energy escape of hot air is high, the energy consumption is too high during use, and the efficiency will also slow down. At the same time, before baking mooncakes, manual spraying operation on the mooncake cake blanks is still required, which is difficult to standardize the spraying operation and increases the labor cost of production.

[0003] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a hot air circulation baking furnace for mooncake production is proposed to achieve a more practical value purpose. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a hot air circulation baking furnace for mooncake production to solve the problems of high energy escape of the hot air circulation baking furnace during mooncake production resulting in slow efficiency and difficult standardization of manual spraying operation on the cake blanks as mentioned in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A hot air circulation baking furnace for mooncake production, including a furnace body and a cabinet body. It is characterized in that the cabinet body is connected to the lower part of the furnace body, a conveyor belt is arranged on the upper surface of the cabinet body, a atomizing nozzle is connected to the inner top of the front end of the furnace body, the atomizing nozzle is connected to a water pump, the water pump is placed inside the cabinet body, a water tank is connected to one side of the water pump, a heat insulation board is connected to the inside of the furnace body, and the heat insulation board is located on the right side of the atomizing nozzle. A blower is connected to the upper part of the furnace body through bolts, an air duct is arranged above the furnace body, and the air duct is connected to the blower. Heat conduction copper tubes are arranged on both sides inside the furnace body, and the heat conduction copper tubes are arranged below the air duct. Control panels are arranged at both ends above the furnace body.

[0006] Further, the number of the heat conduction copper tubes is multiple groups and is evenly arranged longitudinally along the furnace body.

[0007] Further, a blower is connected to the middle of the air duct, the air inlet of the air duct is located at the rear side of the blower, and the air outlet of the air duct is located at the front side of the blower.

[0008] Further, a honeycomb-shaped deflector is provided at the air outlet of the air duct, a filter screen is provided above the honeycomb-shaped deflector, and the filter screen is located inside the air duct.

[0009] Further, an exhaust gas discharge pipe is provided at the upper rear side of the furnace body.

[0010] Further, water pipes are connected to both sides of the water pump and are respectively connected to the atomizing nozzles and the water tank through the water pipes.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: A hot air circulation baking furnace for mooncake production has an atomizing nozzle installed on the front side of the furnace body. After the mooncake blank is placed on the conveyor belt and enters the furnace body, water spraying operation is carried out on it. By computer control of water spraying, the water spraying operation is standardized, and at the same time, the baking efficiency is improved. After the blank is sprayed with water and enters the baking area, the fan above makes the air inside start to circulate through the air duct. A honeycomb-shaped diffuser plate is provided on the lower surface of the air outlet to make the flow of air more concentrated. At the same time, the heat-conducting copper tubes provided on both sides of the furnace body start to increase the temperature of the internal air. While heating the air of the fan, the energy of the escaping hot air is recovered, thereby solving the problems of slow efficiency caused by high energy escape and difficulty in standardizing the manual water spraying operation for the blank. The specific content is as follows:

[0012] A conveyor belt is installed at the lower front side of the furnace body, and an atomizing nozzle is connected to the upper front side of the furnace body. The atomizing nozzle is connected to the water pump and the water tank below through a water pipe. During operation, through the setting of the numerical control board, water spraying operation is carried out on the mooncake blank fed on the conveyor belt. The water mist sprayed by the atomizing nozzle can moisten the surface of the mooncake blank to avoid cracking during the baking process. At the same time, the water mist sprayed by the atomizing nozzle can wrap around the periphery of the blank to avoid some positions not being moistened. An insulating board is provided at the rear side of the atomizing nozzle, and the other side of the insulating board is the baking area of the furnace body. The insulating board is provided to prevent heat escape, and at the same time, the insulating board can prevent the water mist sprayed by the atomizing nozzle from entering the baking area. Heat-conducting copper tubes are provided on both sides of the center of the furnace body, and a fan is connected above the center of the furnace body. The fan is connected to the internal baking area of the furnace body through an air duct. When the fan operates, it drives the air in the baking area to form wind, which circulates in the baking area through the air duct. A honeycomb-shaped diffuser plate is provided at the air outlet of the air duct, and a filter screen is provided above the honeycomb-shaped diffuser plate. The filter screen can filter out fine impurities in the wind to prevent the impurities from contaminating the baked objects. The honeycomb-shaped diffuser plate makes the direction of the wind more concentrated, preventing a large amount of air from escaping to the surroundings. Heat-conducting copper tubes are provided on both sides of the furnace body below the air duct. The heat-conducting copper tubes drive the temperature of the baking area to rise through heating, and make the wind driven by the fan become hot air. At the same time, the heat-conducting copper tubes provided on both sides can also recover the heat of the escaping hot air, so that the temperature of the entire baking area will not be high and low due to the energy escape of the hot air, stabilizing the temperature during the baking process. The energy captured by the heat-conducting copper tubes can be transferred to the circulating air flow again, saving energy consumption. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figure 1 - Figure 3 , the present utility model provides a technical solution: a hot air circulation baking oven for mooncake production, including a furnace body 1 and a cabinet body 2. The lower part of the furnace body 1 is connected to the cabinet body 2. The front end of the furnace body 1 is an input port, and the rear end is an output port. A conveyor belt 6 is provided on the upper surface of the cabinet body 2. The conveyor belt 6 can convey the made mooncake blanks into the furnace body 1. Place the made mooncake blanks on a metal plate body, and then place them on the conveyor belt 6. After starting the baking work through the control panel 11 provided on both sides above the furnace body 1, the machine will start, and the conveyor belt 6 can send the mooncake blanks into the furnace body 1.

[0019] At the top inside the front end of the furnace body 1, an atomizing nozzle 7 is connected. The atomizing nozzle 7 is connected to a water pump 13 placed inside the cabinet body 2 through a water pipe 12, and the water pump 13 is connected to a water tank 14 through the water pipe 12. When the prepared mooncake dough is placed on the metal disc and conveyed into the furnace body 1 through the conveyor belt 6, the machine will control the atomizing nozzle 7 to spray the water sucked up by the water pump 13 into water mist towards the lower conveyor belt direction, and evenly spray the water mist on the mooncake dough to prevent the mooncake dough from cracking during the subsequent baking process due to surface drying. An insulating board 15 is connected to the furnace body 1 behind the atomizing nozzle 7, and a gap is left below the insulating board 15 for the mooncake dough to pass through. When the atomizing nozzle 7 sprays, the insulating board 15 can block the water mist from entering the subsequent furnace body 1 and affecting the baking temperature.

[0020] The air duct 3 is arranged on the upper surface of the furnace body 1. A blower 4 is connected to the center of the air duct 3, and the blower 4 is bolted above the furnace body 1. The air duct 3 at the rear side of the blower 4 is the suction port, and the air duct 3 at the front side of the blower 4 is the blowout port. The air duct 3 at the front side of the blower 4 passes through the furnace body 1 and is connected to the internal baking space, and a honeycomb diffuser plate 9 is arranged at the outlet position of the front side air duct 3. A filter net 8 is arranged above the honeycomb diffuser plate 9. After starting the blower 4, the air in the furnace body 1 is sucked in from the air duct 3 at the rear side of the blower 4, passes through the air duct 3 and the filter net 8. The filter net 8 can filter out the tiny impurities in the air to prevent the impurities from entering the furnace of the furnace body 1 and affecting the hygiene of the mooncake dough. The filtered air flow blows downward through the air duct 3 over the honeycomb diffuser plate 9. The honeycomb diffuser plate 9 is regularly arranged with honeycomb-shaped holes, which sorts out the scattered air flow, makes the blowing direction of the air flow concentrated, strengthens the wind force of the formed wind, and can also prevent the air from escaping in large quantities to the surrounding. The air flow passing through the honeycomb diffuser plate 9 moves towards the air duct 3 at the rear suction port under the drive of the air in the furnace, thus forming a wind circulation area for baking inside the furnace body 1.

[0021] Heat-conducting copper tubes 5 are respectively arranged on both sides inside the furnace of the furnace body 1. Multiple groups of heat-conducting copper tubes 5 are arranged along the longitudinal direction of the furnace body 1. By heating, the heat-conducting copper tubes 5 generate heat, thereby increasing the temperature inside the furnace of the furnace body 1 to meet the baking requirements. The circulating air formed through the air duct 3 forms a hot air circulation during the heating of the heat-conducting copper tubes 5 on both sides, and evenly bakes the mooncake dough sent from the conveyor belt 6. The heat-conducting copper tubes 5 are in direct contact with the circulating hot air. While the wind takes away the heat of the heat-conducting copper tubes 5 and transfers it to the mooncake dough, the heat-conducting copper tubes 5 also recover the heat in the wind that has not been absorbed by the mooncake dough from the contact with the circulating hot air, reducing the overall energy consumption of the furnace body 1. At the same time, because the escaped heat is carried by the wind to the heat-conducting copper tubes 5, the stability of the temperature inside the furnace is improved, which is more conducive to the baking of mooncakes. The waste gas generated by heating the heat-conducting copper tubes 5 is discharged through the waste gas discharge pipe 10 arranged above the furnace body 1 to prevent the components outside the baking furnace from overheating.

[0022] When the baking is completed, the mooncake blank will be conveyed out from the output port at the rear end of the furnace body 1 through the conveyor belt 6, and then enter the next process.

[0023] Working principle: When using this hot air circulation baking furnace for mooncake production, place the mooncake blank in a metal heat-conducting plate body, and then place it on the conveyor belt 6 above the cabinet body 2. After setting the working time through the control panels 11 respectively arranged on both sides above the furnace body 1 and turning on the baking furnace, the conveyor belt 6 will send the mooncake blank and the metal plate body into the furnace for baking preparation. At the top inside the front end of the furnace body 1, there is an atomizing nozzle 7. The atomizing nozzle 7 is connected to a water pump 13 through a water pipe 12. When the mooncake blank enters the furnace, the water pump 13 will transport the water in the connected water tank 14 to the atomizing nozzle 7, spraying out a water mist that evenly covers the mooncake blank to moisten the surface of the mooncake blank and prevent the blank from cracking during baking. Behind the atomizing nozzle 7, there is a heat insulation board 15. The heat insulation board 15 can prevent the water mist sprayed out by the atomizing nozzle 7 from entering the subsequent furnace body and affecting the operation of the machine. When the mooncake blank is completely moistened, the conveyor belt 6 will carry the blank through the aisle under the heat insulation board 15 and enter the baking area of the furnace body 1. On both sides inside the furnace of the furnace body 1, there are heat-conducting copper tubes 5. There are multiple groups of heat-conducting copper tubes 5, and the heat-conducting copper tubes 5 are arranged longitudinally along the furnace body 1. After the mooncake blank enters the furnace, the heated heat-conducting copper tubes 5 start to radiate heat to heat the space inside the furnace, thereby starting to bake the mooncake blank. Above the furnace body 1, there is a blower 4 connected by bolts. On both sides of the blower 4, there are air ducts 3. The rear side of the blower 4 is the suction port, and the front side is the blowing port. The front air duct 3 is connected to the space inside the furnace of the furnace body 1, and at the blowing port of the air duct 3, there is a honeycomb-shaped diffuser plate 9. Above the honeycomb-shaped diffuser plate 9, there is a filter screen 8. The blower 4 sucks the hot air from the lower part of the furnace through the rear air duct 3 and transports it to the front air duct 3 of the blower 4. After filtering the tiny impurities carried therein through the filter screen 8, the air flow direction is adjusted through the honeycomb-shaped diffuser plate 9 to make the air flow in the same direction, increasing the air volume and reducing energy consumption. The hot air heated by the heat-conducting copper tubes 5 forms a circulating hot air flow inside the furnace. The hot air transfers the heat on the heat-conducting copper tubes 5 to the mooncake blank. The heat that has not been transferred will be carried by the hot air to contact the heat-conducting copper tubes 5, keeping the temperature of the heat-conducting copper tubes 5 at the set temperature, preventing the temperature inside the furnace from being too high or too low, and at the same time recovering the heat of the hot air and reducing the energy consumption for maintaining the temperature of the heat-conducting copper tubes 5. After being baked by the hot air circulation, the mooncake blank and the metal plate body are sent out of the furnace body 1 through the conveyor belt 6. Above the output port at the rear end of the furnace body 1, there is a control panel 11. After the blank is out of the furnace, the machine can be operated to shut down, and then the blank is taken away and entered into the next process of the mooncake.
