Description
Technical Field
[0001] The utility model relates to the technical field of food truck drying, in particular to a heat circulation structure for a food truck drying bin. Background Technique
[0002] A food truck is a box-shaped trolley used to transport meals on an airplane flight. In meal production, flight catering enterprises need to clean a large number of food trucks. To ensure food safety, the food trucks used to assemble meals need to be kept dry without water accumulation after cleaning. The existing methods for drying food trucks mostly adopt static cooperation with manual wiping. This method is simple to operate and has a low operation cost. However, the problems are that drying in a static state is slow and the wiping and cleaning strength is insufficient, posing a food safety hazard. For the drying of a large number of food trucks, it cannot be efficiently applied;
[0003] Therefore, in view of this problem, the existing design proposes a food truck drying bin, that is, moving the cleaned food truck into the drying bin and using high-temperature gas to dry the truck. However, when the existing drying bin is in operation, it is impossible to effectively control the flow of the high-temperature gas in the bin. When facing food trucks of different heights, the air flow direction or distribution position cannot be effectively adjusted, resulting in inaccurate targeting during drying, slow drying speed, low efficiency and other problems;
[0004] Therefore, in view of the above existing problems, this technical solution proposes a heat circulation structure for a food truck drying bin. Content of the Utility Model
[0005] The purpose of the utility model is to provide a heat circulation structure for a food truck drying bin to solve the problems raised in the above background technique.

The output end of the PTC heating system is connected with multiple groups of heat transfer pipes. The high-temperature gas generated in the PTC heating system is transmitted to the inside of the food truck drying box through the heat transfer pipes. Uniformly distributed top fixed discharge ports are provided on the inner top of the food truck drying box. The top of the top fixed discharge ports is connected with a high-temperature gas transfer cavity opened at the bottom of the food truck drying box. The bottom ends of the heat transfer pipes are all connected to the high-temperature gas transfer cavity. That is, under the transmission of the heat transfer pipes, the high-temperature gas is transferred to the high-temperature gas transfer cavity, and then evenly diffuses downward along the inner top of the food truck drying box through the top fixed discharge ports to perform covering drying on the washed food truck placed inside the food truck drying box. At the same time, a discharge port is provided on the inner side wall of the food truck drying box, and a discharge pipe is connected to the outside of the discharge port. An exhaust fan is provided on the discharge pipe. That is, under the pumping of the exhaust fan, the gas inside the food truck drying box is discharged outward to maintain the continuous cyclic transfer of the high-temperature gas inside the food truck drying box. A side discharge groove is provided on the inner wall of the food truck drying box on the side opposite to the discharge port. A set of side moving discharge rows is arranged in a lifting manner inside the side discharge groove. An external connection of the side moving discharge rows is provided with a lifting mechanism. Under the action of the lifting mechanism, the side moving discharge rows are controlled to move vertically along one side of the food truck to perform targeted high-temperature gas diffusion drying on food trucks of different heights, and at the same time, accelerate the fluidity of the gas inside the food truck drying box to ensure that the food truck is fully dried. One side of the outside of the side moving discharge rows is connected with a high-temperature gas transmission component. The high-temperature gas transmission component moves following the power mechanism and is connected to one of the heat transfer pipes at the top to ensure that the high-temperature gas in the heat transfer pipe can be transferred to the side moving discharge rows for mobile output and recycling.

[0017] Please refer toFigures 1 - 4 , a heat circulation structure for a drying bin of a food food truck, comprising a food food truck drying box 10 and a PTC heating system 11; a food food truck inlet and outlet is provided on one side of the front of the food food truck drying box 10, and the PTC heating system 11 is installed on one side of the top of the food food truck drying box 10. The output end of the PTC heating system 11 is connected to a plurality of heat transfer pipes 12. The high-temperature gas generated in the PTC heating system 11 is transmitted to the inside of the food food truck drying box 10 through the heat transfer pipes 12. A top fixed discharge port 14 evenly distributed is provided on the inner top of the food food truck drying box 10. The top of the top fixed discharge port 14 is connected to a high-temperature gas transfer cavity opened at the bottom of the food food truck drying box 10. The bottom ends of the heat transfer pipes 12 are all connected to the high-temperature gas transfer cavity. That is, under the transmission of the heat transfer pipes 12, the high-temperature gas is transferred to the high-temperature gas transfer cavity, and then evenly diffuses downward along the inner top of the food food truck drying box 10 through the top fixed discharge port 14 to cover and dry the washed food food truck placed inside the food food truck drying box 10. At the same time, a discharge port 31 is provided on the inner side wall of the food food truck drying box 10. The outside of the discharge port 31 is connected to a discharge pipe 30. A exhaust fan 29 is provided on the discharge pipe 30. That is, under the pumping of the exhaust fan 29, the gas inside the food food truck drying box 10 is discharged outward, so as to maintain the continuous circulation transfer of the high-temperature gas inside the food food truck drying box 10. A side discharge groove 20 is provided on the inner wall of the food food truck drying box 10 on the side opposite to the discharge port 31. A set of side moving discharge rows 19 are arranged in a lifting manner inside the side discharge groove 20. The outside of the side moving discharge rows 19 is connected to a lifting mechanism. Under the action of the lifting mechanism, the side moving discharge rows 19 are controlled to move vertically along one side of the food food truck to perform targeted high-temperature gas diffusion drying on food food trucks at different heights, and at the same time accelerate the fluidity of the gas inside the food food truck drying box 10 to ensure that the food food truck is fully dried. One side of the outside of the side moving discharge rows 19 is connected to a high-temperature gas transmission component. The high-temperature gas transmission component moves with the power mechanism and is connected to one of the heat transfer pipes 12 at the top, so as to keep the high-temperature gas in the heat transfer pipes 12 transferred to the side moving discharge rows 19 for mobile output and recycling.
[0018] In the embodiment of the present invention, the side discharge groove 20 has the same length as the top fixed discharge port 14 to ensure that the output high-temperature gas can cover and dry a plurality of food food trucks placed inside the food food truck drying box 10. A set of lifting mechanism boxes 18 are provided outside the power mechanism. The lifting mechanism boxes 18 are fixed on the outer wall of the food food truck drying box 10. At the same time, the top of the high-temperature gas transmission component movably passes through the lifting mechanism box 18 and is connected to one of the heat transfer pipes 12.
[0019] In an example of the present invention, for the PTC heating system 11, the process of generating high-temperature gas involves the conversion of electrical energy into heat energy. Then, through the heating effect of the PTC heater, the heat is transferred to the surrounding medium, and finally high-temperature gas is generated. When the PTC heater is powered on, an electric current passes through the PTC ceramic heating element. Due to the positive temperature coefficient characteristic of the PTC material, its resistance increases with the increase in temperature, resulting in the generation of Joule heat in the PTC material. In this process, electrical energy is converted into heat energy, causing the temperature of the PTC heater itself and the air in contact with it to rise. As the surface temperature of the heater increases, the surrounding air begins to absorb heat and the temperature gradually rises. When the heated air reaches a certain temperature, it becomes high-temperature gas and can then be guided to the area that needs to be heated or discharged through the ventilation system. The above is the operating principle of the PTC heating system 11. Regarding its structure, components, etc., since they belong to the prior art, they will not be elaborated here.
[0020] As a preferred embodiment of the present invention, the lifting mechanism includes a lead screw 23 rotatably arranged vertically in the middle of the lifting mechanism box 18. The top of the lead screw 23 is rotatably connected to the inner top wall of the lifting mechanism box 18, and the bottom end is connected to a servo motor 24 fixed inside the lifting mechanism box 18. A nut 22 is threadedly connected to the lead screw 23. A guiding device for restricting its self-rotation is provided on the nut 22. One side of the nut 22 facing the inside of the side discharge groove 20 is connected to a fixed rod. A lifting slideway 21 is opened on the side wall of the side discharge groove 20 corresponding to the fixed rod. The fixed rod slides vertically along the lifting slideway 21, and the end of the fixed rod is fixedly connected to the side moving discharge row 19. Start the servo motor 24 to drive the lead screw 23 to rotate, control the nut 22 to move back and forth along the lead screw 23, and then control the side moving discharge row 19 to move up and down inside the side discharge groove 20;
[0021] The high-temperature gas transmission component includes a main transmission pipe 15 connected to the heat transfer pipe 12. Two auxiliary transmission pipes 17 are connected to the end of the main transmission pipe 15. The bottom ends of the auxiliary transmission pipes 17 pass through the top of the lifting mechanism box 18 movably and extend downward to be connected to a telescopic hose 28.

The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, and will not explain the electrical control. By pushing the food truck to be dried into the food truck drying box 10, and then according to the height of the food truck and the drying intensity, start the PTC heating system 11 to operate to generate high-temperature gas, and then convey it into the food truck drying box 10 through the top fixed discharge port 14, and dry the food truck from top to bottom by gas flow. Then, according to the height of the food truck, start the servo motor 24 to drive the nut 22 to lift and lower, and then drive the side moving discharge row 19 to move up and down.
