Description

Technical Field

[0001] The utility model belongs to the technical field of drying, and particularly relates to a heating module device. Background Art

[0002] The heating device relies on heat conduction to heat materials, and the heating speed is relatively slow. During the heating process, the heat loss directly affects the heating effect of the heating device.

[0003] As in the Chinese patent document "CN105783441A, a single-box drying device with uniform heating", it includes a box body. A cavity is arranged inside the box body, and a heat-insulating layer is arranged on the inner wall of the box body. An air extractor for extracting air into the cavity is fixedly arranged at the upper end of the box body. A plurality of infrared heating devices are arranged inside the heat-insulating layer, and the plurality of infrared heating devices surround and closely adhere to the inner wall of the heat-insulating layer. A PLC control box is arranged on one side of the box body, and the PLC control box is connected to the plurality of infrared heating devices through wires. A plurality of extractable material trays are also arranged inside the cavity. The odd-numbered layers of the plurality of material trays are detachably connected to the inner wall of one side of the box body, and the even-numbered layers are detachably connected to the inner wall of the other side of the box body. And a meandering air flow channel is formed between the plurality of material trays. The plurality of material trays are all screen trays with wooden skeletons; an air inlet is arranged at the lower part of the box body.

[0004] The above device only fixes the tray on one side. When the tray bears too heavy an object, due to uneven stress, the tray may be deformed, and then the items placed on it may slip or overturn. At the same time, by arranging a number of infrared heating devices around the inner wall of the heat-insulating layer to heat the tray, when items are placed on the tray, the infrared heating devices cannot penetrate the items, so that the middle tray can only be heated by the infrared heating devices on both sides, resulting in uneven heating.

[0005] The purpose of the utility model is to provide a heating module device to solve the problems put forward in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A heating module device includes an outer support frame. A plurality of fixing plates are fixedly connected inside the outer support frame by rivets. A tray is placed between every two fixing plates, and each tray abuts against the upper end surface of the fixing plate below it. Heat generating sheets electrically connected to an external controller through cables are arranged on the lower end surfaces of the plurality of fixing plates, and the heat generating sheets heat the upper and lower ends of the tray respectively.

[0008] Further, the outer support frame includes a top plate and a bottom plate, and a plurality of through holes I are provided through both the bottom plate and the top plate.

[0009] Further, a plurality of through holes two for cables to pass through are provided on the outer support frame.

[0010] Further, on the side of the outer support frame away from the fixed plate, an outer cover for placing cables is detachably installed by screws.

[0011] Further, fixing frames for fixing the trays are provided on both sides of the plurality of trays.

[0012] Further, the tray includes an extending portion extending outwards, and two cross plates extending towards the tray are provided on the fixing frame. A clamping groove for clamping the tray is formed between the two cross plates, and baffles are provided at the ends of the two cross plates.

[0013] Further, a temperature detector is installed at the top of the outer support frame.

[0014] Advantages of the present utility model:

[0015] The present utility model is small, convenient to carry and install, greatly improving the stability and durability during use. By using a fixing plate with good thermal conductivity, when the heating sheet generates heat, the heat is transferred to the fixing plate, and the fixing plate directly heats the bottom of the tray, thereby dehydrating, evaporating and drying the food on the tray. At the same time, since there is a heating sheet above each tray, the heating sheet above directly heats the tray. Through this design, the tray receives the heat from the upper and lower heating sheets simultaneously, making the food heated evenly, thereby realizing rapid dehydration, evaporation and drying of the food, and using heat energy to reduce the moisture content in the material, so as to achieve the purpose of anti-corrosion and extending the storage period.

Specific embodiments

[0025] 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.

[0026] Please refer to Figures 1-7 ;

[0027] For the heating module device of the present utility model, by using the fixing plate 2 with good thermal conductivity, when the heating sheet 4 generates heat, the heat is transferred to the fixing plate 2, and the fixing plate 2 directly heats the bottom of the tray 3, so that the food on the tray 3 is dehydrated, evaporated and dried. At the same time, since there is a heating sheet 4 above each tray 3, the upper heating sheet 4 directly heats the tray 3. Through this design, the tray 3 receives the heat of the upper and lower heating sheets 4 at the same time, making the food heated evenly, thereby realizing the rapid dehydration, evaporation and drying of the food.

[0028] Embodiment 1 specifically includes an outer support frame 1. Inside the outer support frame 1, a number of fixing plates 2 are fixedly connected by rivets. The number of fixing plates 2 is arranged and riveted vertically, greatly improving the stability and durability during use. The fixing plates 2 are made of a metal material with good thermal conductivity, such as a copper alloy or stainless steel material that is easy to conduct heat. A tray 3 is placed between every two fixing plates 2. Each tray 3 abuts against the upper end surface of the fixing plate 2 below it. The tray 3 is used to place foods such as fruits, vegetables or meats. If the number of trays 3 is N, then the number of fixing plates 2 is N + 1. Therefore, the number of heating elements 4 is also N + 1. Specifically, in this utility model, the number of trays 3 is six, so the number of fixing plates 2 is 7, and the number of heating elements 4 is also 7. Heating elements 4 are provided on the lower end surfaces of a number of fixing plates 2 and are electrically connected to an external controller through cables. The heating elements 4 heat the upper and lower ends of the tray 3 respectively. The installation method of the heating element 4 in this utility model is specifically as follows: First, vulcanize the lower end surface of the fixing plate 2, and then paste the heating element 4 onto the lower end surface of the fixing plate 2, so that the heating element 4 can be firmly adhered to the fixing plate 2. The size of the heating element 4 is the same as the area where the tray 3 places food. After installation, the upper heating element 4 is aligned with the opening of the tray 3, so that the heating element 4 can heat the tray 3 evenly. Since the fixing plate 2 has good thermal conductivity, when the heating element 4 generates heat, the heat is transferred to the fixing plate 2, and the fixing plate 2 directly heats the bottom of the tray 3, thereby dehydrating, evaporating and drying the food on the tray 3. At the same time, since there is a heating element 4 above each tray 3, the upper heating element 4 directly heats the tray 3. Through this design, the tray 3 receives the heat from the upper and lower heating elements 4 at the same time, and the heating is uniform, thereby realizing rapid dehydration, evaporation and drying of the food. Specifically, it uses heat energy to reduce the moisture content in the food, so as to achieve the purpose of anti-corrosion and extending the storage period.

[0029] Specifically, first place the food in the tray 3, then place the tray 3 on the fixing plate 2, start the heating element 4, dehydrate, evaporate and dry the food on the tray 3 through the heating element 4. After drying is completed, take out the food and store it. Compared with existing products on the market, the space utilization rate of this device is large, and more food can be dried. Through this effective drying treatment, not only can the quality of the product be maintained, but also the production efficiency can be improved.

[0030] In this embodiment, the outer support frame 1 includes a top plate 5 and a bottom plate 6. The outer support frame 1, the bottom plate 6, and the top plate 5 are all made of heat-insulating materials, such as glass fiber materials, which can effectively isolate heat and prevent the heat generated by the heating sheet 4 from being transferred to the fixing plate 2, and then the fixing plate 2 transfers the heat to the bottom plate 6, the top plate 5, and the outer support frame 1, causing the temperatures of the bottom plate 6, the top plate 5, and the outer support frame 1 to rise, resulting in burns when the staff takes out the heating device. This improves safety. At the same time, it makes the heat concentrate on the fixing plate 2, reduces heat loss, and improves the drying efficiency of food.

[0031] Further, a plurality of first through holes 7 are provided through the bottom plate 6 and the top plate 5. The first through holes 7 are used to reduce the weights of the bottom plate 6 and the top plate 5, reduce the weight of the heating group device, and enable the heating module device to be easily lifted and conveniently carried.

[0032] In this embodiment, a plurality of second through holes 12 for cables to pass through are provided on the outer support frame 1. The cables pass through the second through holes 12 and are electrically connected to an external control device.

[0033] Further, an outer cover 8 for placing cables is detachably installed on the side of the outer support frame 1 away from the fixing plate 2 by screws. One side of the outer cover 8 facing the outer support frame 1 is hollowed out to form a cavity for placing cables.

[0034] Embodiment 2: Fixing frames 21 for fixing the trays 3 are provided on both sides of the plurality of trays 3. The fixing frames 21 and the fixing plate 2 are integrally formed structures to improve the service life of the fixing frames 21. Since the fixing frames 21 and the fixing plate 2 are integrated, the fixing frames 21 also have good thermal conductivity. When the fixing plate 2 receives the heat generated by the heating sheet 4, this part of the heat will be quickly transferred to the fixing frames 21, and the fixing frames 21 are used to heat both sides of the trays 3, enabling the heating module device to heat the trays 3 from multiple directions, further improving the drying efficiency. At the same time, the fixing frames 21 can be used to position the trays 3 to ensure that the positions of the trays 3 are accurately placed.

[0035] Further, the tray 3 includes an extending portion 31 extending outward. Two cross plates 23 extending toward the tray 3 are provided on the fixing frame 21. A clamping groove 24 for clamping the tray 3 is formed between the two cross plates 23. A baffle 22 is provided at the ends of the two cross plates 23. The baffle 22 is used to limit the insertion of the tray 3. Through the arrangement of the fixing frame 21 and the baffle 22, when the tray 3 is completely pushed in and abuts against the baffle 22, the tray 3 is exactly aligned with the heating sheet 4. When installing the tray 3, the extending portion 31 of the tray 3 is inserted into the clamping groove 24 and slides along the clamping groove 24 until the tray 3 abuts against the baffle 22 to complete the installation.

[0036] In this embodiment, since this heating module device is used to be placed in the evaporation chamber to heat food, so as to dehydrate, evaporate and dry the food, a temperature detector 11 is installed at the top of the outer support frame 1. The temperature detector 11 is electrically connected to an external controller and a heating sheet 4. And this heating module device starts after the temperature inside the drying chamber reaches -50 degrees Celsius, and melts the ice and dehydrates the food on the tray 3. Specifically, the microprocessor controls the temperature detector 11 to collect the temperature inside the drying chamber every 30 seconds, and then stores the preset temperature of -50 degrees Celsius in the data memory through the external controller. The temperature detector 11 transmits the temperature data to the microprocessor, and the microprocessor then transmits the data to the comparison module. The comparison module compares the temperature data transmitted by the microprocessor with the preset temperature stored in the data memory. When the temperature inside the drying chamber reaches -50 degrees Celsius, the comparison module transmits the data to the microprocessor again, and the microprocessor then feeds back the data to the external controller. The external controller controls the heating sheet 4 to generate heat, so as to melt the ice, dehydrate, evaporate and dry the food, without manual operation.
