Description

Technical Field

[0001] The invention relates to a heating device, in particular to a production device for boiling and baking peeled walnuts. Background Art

[0002] The processing process of walnuts includes: peeling the walnuts, then adding the peeled walnuts into the boiling equipment for boiling; after boiling, transferring them to the corresponding low-temperature drying equipment for low-temperature drying; after drying, transferring them to the corresponding high-temperature baking equipment for high-temperature baking.

[0003] At present, whether it is water boiling equipment or low-temperature and high-temperature drying equipment, most of them use electric heaters or gas heaters to heat the medium, and then heat the walnuts through the medium. For example, in the equipment for boiling walnuts, water is heated by an electric heater, and then the water heats the walnuts. For example, in low-temperature drying equipment, a heater is used to heat the air, and then the hot air is used to dry the walnuts at a low temperature. For example, in high-temperature baking equipment, external wind is blown in and heated into high-temperature steam by an internal heater, and the walnuts are completely dried by high-temperature steam. However, the above-mentioned processing processes all have a great pain point in actual use, that is, the energy consumption is high during the heating process, especially for large-scale agricultural products such as walnuts. If one kilowatt-hour of electricity is consumed in a single batch processing process, thousands of more electricity will be consumed in the process of water boiling, low-temperature drying, and high-temperature drying. The investment of enterprises in energy often accounts for a very high part of the cost.

[0004] Therefore, this case aims to provide a peeled walnut boiling and baking production equipment that can effectively reduce the energy consumption in the process of walnut boiling and drying, saving the company's costs; and can retain the temperature inside the equipment, saving energy while ensuring heating efficiency.

An inverted "X"-shaped air guide hopper is arranged inside the hanging frame, and the air guide hopper is communicated with the air inlet cylinder. Both ends of the air guide hopper are extended and fixed to the inner wall of the drying box.

[0023] The beneficial effects of the present invention are:

[0024] In the existing heating process, natural gas and electric heaters are mostly used. However, this heating form not only consumes a lot of electricity, but also due to the low heat retention, the walnuts are prone to unevenness during the boiling and heating processes. Therefore, the present invention uses a glass heating plate in the processes of boiling, low-temperature drying and high-temperature baking. An electric heating film is sprayed on the heating plate. Far-infrared waves are generated by energizing the electric heating film. The semiconductor far-infrared wave heating technology can not only quickly heat the medium, but also the far-infrared waves can be directly radiated to the walnuts to quickly heat the inside of the walnuts. The infrared wave has a strong penetrating ability, and even walnuts piled higher can act on the walnuts on the top. The heating effect is far better than the existing heating method. In addition, since the glass tube has better thermal insulation performance once heated, intermittent heating can be used to reduce energy consumption.

[0025] During the entire process of boiling and heating walnuts, the mesh frame carries hundreds of kilograms of walnuts. Although they can be partially heated by far-infrared waves, it still takes a long time to raise the heat to a suitable cooking temperature compared to a large-capacity heating chamber. To this end, the present invention adds a chamber circulation component that spans the bottom and top of the entire heating chamber. The water heated by the glass tube at the bottom can be pumped to the top of the mesh frame through a circulation structure, so that the walnuts on the top of the mesh frame can also be quickly heated, thereby improving the overall thermal circulation speed.

[0026] Although the walnuts on the top can also be quickly heated by the chamber circulation component, it still cannot solve the problem that the walnuts are half in water and half in air after floating up during the heating process. In this regard, the present invention can press the walnuts into the water through the top pressure seat through the added top pressure immersion component, so that the walnuts are completely immersed in the water. However, since the thickness of the cover plate cannot be set too thick, the driving structure cannot be set even if it is hollowed out. If the top pressure seat itself is set with a convex shape, the overall volume is not convenient for daily opening and closing. Therefore, after the cover plate seals the heating chamber and the chamber circulation component is started, the upper accommodating cavity tube is pushed out with the pumped water and pushes the top pressure seat downward, so that the top pressure seat will protrude and apply pressure to the walnuts on the water surface during heating. When the heating is completed and it is about to be opened, the upper accommodating cavity tube retracts, so the top pressure seat loses power and can rebound. Before opening the cover, the top pressure seat will retract to the inner side of the cover plate, which does not affect the use of opening the cover, thereby achieving the effect of applying pressure when closing the cover and retracting when opening the cover.

[0027] During the feeding process of the present invention, the front end portion of the material blocking frame moves forward to the outside of the drying chamber. At this time, the driving motor drives the driving shaft to rotate until the driving block is away from the material paving board, and the supporting roller on the tightening rod of the vibration assembly is rollingly supported on the bottom side surface of the material paving board, so that the rear side of the material paving board can be tilted downward by no more than 5°. When the external unloading mechanism dumps the material to the front side of the material blocking frame, the vibration motor of the vibration assembly is started, and under the action of vibration and inclined material guiding, the material can be evenly laid backward; after the material is laid, the piston rod of the driving cylinder is reset, and the electric heating film glass plate starts heating to dry the material in the drying chamber; after the drying is completed, the piston rod of the driving cylinder is extended again to drive the front end of the material blocking frame to move forward to the outside of the drying chamber, and at this time, the driving motor drives the driving shaft to rotate until the driving block is tightened on the material paving board, so that the front side of the material paving board is tilted downward by no more than 5°, and then the vibration motor of the vibration assembly is started, so that under the action of vibration and inclined material guiding, the material is evenly gathered forward for collection. This can effectively and significantly improve the loading and unloading efficiency of materials during the drying process, thereby significantly improving the overall drying processing efficiency of the materials.

[0028] The front end of the material laying plate of the present invention is provided with a group of symmetrically inclined material discharging guide plates, the front ends of the material discharging guide plates are arranged at intervals, and the front end surface of the material blocking frame is provided with a corresponding material discharging port, and a corresponding sealing plate is installed at the material discharging port that can be opened and closed. When the material is fed, the sealing plate closes the material discharging port installed on the material blocking frame, so as not to affect the feeding and normal drying operations, and when the material is discharged, the sealing plate is opened, so that the material is guided by the material discharging guide plate and gathered to the material discharging port of the material blocking frame for output. Thereby, the material discharging efficiency is further improved, so as to further assist in improving the material loading and unloading efficiency during the drying process, thereby further improving the overall drying processing efficiency of the material.

[0029] The electric heating film heater of the present invention comprises a group of electric heating film glass plates obliquely installed at the upper front and rear ends of the drying chamber, and a heat pump air heater fixedly installed at the lower side of the rear end of the drying chamber. At the initial stage of drying, the heat pump air heater and the electric heating film glass plate located at the rear end of the drying chamber start heating respectively. After the hot air generated by the heat pump air heater flows through the electric heating film glass plate located at the upper rear end of the drying chamber, the hot air is quickly transported into the area where the material is located under the guidance of the electric heating film glass plate located at the upper rear end of the drying chamber, so that the drying temperature in the drying chamber can be quickly increased, and the initial heating can be more comprehensively applied to the material; after the drying temperature in the drying chamber reaches the set value, the heat pump air heater can be turned off, and the electric heating film glass plate located at the front end of the drying chamber can be turned on, so that the temperature in the drying chamber can be kept within the range required for drying under the premise of low energy consumption. In this process, the far-infrared waves generated by the electric heating film glass plate when it is powered on can also directly act on the material, so that the drying efficiency of the material can be significantly improved. Thereby, the drying efficiency of the material can be effectively improved without increasing the drying temperature, and the energy consumption required for material drying can be effectively reduced.

[0030] During the high-temperature baking process, walnuts will generate moisture during the baking process, and due to the layout of the electric heating component, hot air and moisture are more difficult to discharge. The traditional exhaust structure is easy to discharge the heat together. In this regard, the present invention adds a two-way guide component. First, a lower guide is set at the bottom of the walnut conveyor belt to suck away the moisture overflowed from the bottom of the walnuts during baking, and at the top position, an upper guide is set down to suck away the moisture overflowed from the top of the walnuts during baking, thereby completing the rapid extraction of moisture in two directions. Since the setting position is directional, less hot air is absorbed during the extraction process, and more directly acts on moisture. In order to avoid the stacked walnuts being too high and unable to evenly guide the moisture up and down, an equalizing block is also set on the side of the upper guide facing the walnut input direction, so that the walnuts are evenly flattened before extraction, so as to avoid moisture from being retained in the middle of the stacked walnuts and affecting the baking effect.

[0031] If the existing conveyor belt is directly used, the lower guide member cannot be set due to the closed belt surface of the conveyor belt. If the chain plate conveyor belt in the prior art is used, the chain plate conveyor belt has a number of uniform small holes, which will cause the hot air to flow directly downward and be taken away by the lower guide member. Therefore, on the basis of the electric heating component and the two-way guide component, the present invention sets the two sides of the chain plate in the present invention as concave and convex surfaces, so that leakage holes with a certain gap will appear at the connection position of the chain plate. In the normal transmission and drying stages, the walnuts will block the leakage holes to avoid the direct discharge of the hot air generated by the electric heating component. In the dehumidification stage, when the lower guide member is started, the moisture of the walnuts will be directly discharged through the leakage holes, and the moisture overflowing from the upper end of the walnuts will be normally discharged through the upper guide member, thereby achieving the goal of being able to discharge the moisture from the upper and lower ends in time and retain the heat in the area between the electric heating component and the walnut, thereby reducing heat loss and energy consumption.

[0032] In the process of setting some existing top heating structures, the heating structures are arranged at intervals, so that a dehumidification structure is arranged in the gaps between the heating structures. Although the purpose of dehumidification can be achieved, it is inevitable that a large part of the hot air will be taken away. In this regard, the present invention connects the electric heating plates together through a transition plate, and the transition plate is also made of glass, so as to form a continuous surface on the top surface of the walnut to prevent the hot air from overflowing from the top;

[0033] Although a continuous surface is formed, the problem of moisture removal still needs to be considered. In this regard, the present invention further proposes to set a hanging frame at the position of the transition plate. The hanging frame is fixed on the transition plate and extends to the top of the conveyor belt. The air intake pipe set on the hanging frame is used to introduce the moisture overflowing from the top, and the moisture sucked by the air intake pipe is discharged through the air guide hopper, thereby achieving the purpose of moisture removal and retaining the majority of hot air.

In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0057] Reference Figures 1 to 20 In the whole process of peeling walnuts, the walnuts need to be boiled, dried at low temperature and baked at high temperature. Correspondingly, the production equipment for boiling and baking peeled walnuts in this embodiment includes four parts, one part is a boiling mechanism, one part is a low-temperature drying mechanism, one part is a high-temperature baking mechanism, and one part is a transfer mechanism, wherein the transfer mechanism is a gantry or a traveling crane arranged on the top of the plant. The transfer mechanism first immerses the frame filled with walnuts into the boiling mechanism for cooking, and then transfers the walnuts to the low-temperature drying mechanism after they are cooked, and then dumps them into the low-temperature drying mechanism for low-temperature drying. After the low-temperature drying is completed, the low-temperature drying mechanism automatically flips and dumps the walnuts into a frame, which is hoisted to the initial section of the high-temperature baking mechanism through the transfer mechanism and input into the tunnel-type high-temperature baking equipment for high-temperature baking. The walnuts after high-temperature baking can be directly sold after being collected. For ease of understanding, the three parts of boiling, low-temperature drying and high-temperature baking are explained separately:

[0058] First, the peeled walnuts need to be boiled in water. While cooking the walnuts, the astringency of the walnuts themselves is removed. The boiling mechanism specifically includes a heating chamber 1 for carrying water, a heater 2 arranged in the heating chamber 1, the heater 2 includes a plurality of electrical connection contacts 21 arranged on the outer shell of the heating chamber 1, a plurality of glass tubes 22 are glued to the inside of the heating chamber 1, and the inner side of the glass tube 22 is sprayed with an electric heating film and a silver electrode. After the electric connection contacts 21 are energized, the silver electrode is turned on to allow the electric heating film to heat the water in the heating chamber 1 through the glass tube 22; a chamber circulation component, the heating chamber 1 is movably provided with a mesh frame 11 for accommodating walnuts, the chamber circulation component includes a lower accommodating tube 31 located in the lower half of the heating chamber 1, a circulation structure 32 is locked in the middle of the inner side of the heating chamber 1, and the upper half of the heating chamber 1 is provided with The outlet is higher than the upper accommodating chamber tube 33 of the mesh frame 11, and the circulation structure 32 pumps the water heated by the glass tube 22 to the top of the mesh frame 11 through the lower accommodating chamber 31; a top pressure immersion component, a cover plate 39 is hingedly installed on the top of the heating chamber 1, and the top pressure immersion component includes an inner mounting chamber 41 arranged in the middle of the inner side wall of the cover plate 39, and the two sides of the inner mounting chamber 41 are opened, and a top pressure seat 42 is movably installed in the inner mounting chamber 41. When the cover plate 39 seals the heating chamber 1, the top pressure seat 42 is located above the mesh frame 11. When the circulation structure 32 pumps water into the upper accommodating chamber tube 33, the two upper accommodating chamber tubes 33 move to one side of the top pressure seat 42 and enter the opening of the inner mounting chamber 41 to press the top pressure seat 42 downward, so that the top pressure seat 42 presses the walnuts floating on the water surface downward until they are completely immersed in water.

[0059] The heating chamber 1 in the present embodiment is a rectangular box, but in actual use, the shape of the heating chamber 1 can also be circular or other polygonal structures, as long as the shapes of other structures are changed accordingly. The two sides of the heating chamber 1 are respectively connected to a liquid inlet pipe 8 and a liquid outlet pipe 9, which can facilitate the rapid entry and discharge of water.

[0060] The prior art mostly uses natural gas, electric heaters, and electric heating plates in the heating process, but this heating form not only consumes a lot of electricity, but also easily makes the walnuts boiled unevenly. The boiling effect can only be ensured by extending the heating time, but the power consumption is further increased. In this regard, the present invention adopts a glass tube 22 in combination with an electric heating film, and uses semiconductor far-infrared wave heating technology, which can not only quickly heat water, but also directly radiate far-infrared waves to the walnuts, and quickly heat the inside of the walnuts. The infrared wave has a strong penetrating ability, and even walnuts piled high can act on the walnuts on the top. The heating effect far exceeds the existing heating method, and because the glass tube 22 has better thermal insulation performance once heated, intermittent heating can be used to reduce energy consumption.

[0061] Since the electrical connection contact 21 is arranged outside the heating chamber 1 and a portion located inside the heating chamber 1 is sheathed by the glass tube 22, it will not directly contact the water in the heating chamber 1, thereby ensuring safety.

[0062] The mesh frame 11 in this embodiment is a frame structure in which double-layer meshes are welded together. A metal mesh is used, which has sufficient load-bearing capacity and can allow water to flow in through the mesh holes.

[0063] During the entire walnut heating process, the mesh frame 11 carries several hundred kilograms of walnuts. Although they can be partially heated by far-infrared waves, it still takes a long time to raise the heat to a suitable cooking temperature compared to the large-capacity heating chamber 1. In this regard, the present invention adds a chamber circulation component, which spans the bottom and top of the entire heating chamber 1. The water heated by the glass tube 22 at the bottom can be pumped to the top of the mesh frame 11 through the circulation structure 32, so that the walnuts on the top of the mesh frame 11 can also be quickly heated, thereby improving the overall thermal circulation speed.

[0064] In order to facilitate the placement and lifting of the screen frame 11, a handle may be provided on the screen frame 11, and the screen frame 11 may be lifted by a gantry, thereby reducing the difficulty of lifting and lowering the screen frame 11.

[0065] Although the walnuts on the top can be quickly heated by the chamber circulation component, the problem that the walnuts are half in the water and half in the air after floating up during the heating process cannot be solved. In this regard, the present invention can press the walnuts into the water through the top pressure seat 42 by adding a top pressure immersion component, so that the walnuts are completely immersed in the water. However, since the thickness of the cover plate 39 cannot be set too thick, the driving structure cannot be set even if it is hollowed out. If the convex top pressure seat 42 is set by itself, the overall volume is too large to be convenient for daily opening and closing. Therefore, after the cover plate 39 seals the heating chamber 1 and the chamber circulation component is started, the upper accommodating chamber tube 33 is pushed out along with the pumped water and pushes the top pressure seat 42 downward, so that the top pressure seat 42 will protrude and exert pressure on the walnut on the water surface during heating. When the heating is completed and the lid is about to be opened, the upper accommodating chamber tube 33 retracts, so the top pressure seat 42 loses power and can rebound. Before opening the lid, the top pressure seat 42 will retract to the inner side of the cover plate 39, which will not affect the use of opening the lid, thereby achieving the effect of applying pressure when closing the lid and retracting when opening the lid.

[0066] In fact, the cover 39 is very heavy, and due to high-temperature cooking, the temperature of its surface is extremely high. It is difficult to open it manually. In this regard, the present embodiment proposes that electric support rods 34 are hingedly provided on the two sides of the cover 39, and the bottom end of the electric support rod 34 is hingedly connected to the outside of the heating chamber 1. The cover 39 can be directly controlled by controlling the rise and fall of the electric support rod 34, and an electrical connection relationship can be established between the electric support rod 34 and the circulation structure 32, so that the two have a certain linkage effect, thereby avoiding the phenomenon of accidental touch.

[0067] Since a large-volume mesh frame 11 is provided in the entire heating chamber 1, the volume available for installing the chamber circulation component is actually very small. If it is not installed properly, it is easy to collide with the mesh frame 11 during the process of the mesh frame 11 rising and falling. Therefore, the present invention first sets the lower accommodating tube 31 as an arc-shaped trumpet opening, which is not only convenient for water inlet, but also can be set below the mesh frame 11, and then sets the circulation structure 32 in the gap between the mesh frame 11 and the heating chamber 1, and compensates for the power by increasing the number, so as to minimize the proportion of the circulation structure 32, and finally sets the upper accommodating cavity tube 33 at the top of the circulation structure 32, and pushes it out when needed and retracts it when not needed, and opens and closes according to the heating process. Since the mesh frame 11 also rises and falls with the heating process, the two are not easy to collide.

[0068] The upper accommodating cavity tube 33 and the lower accommodating cavity tube 31 can be clearly seen from the figure, but the setting method of the circulation structure 32 is relatively vague. In the present embodiment, the circulation structure 32 comprises a central cavity 321 welded to the inner wall of the heating chamber 1, and the two ends of the central cavity 321 are respectively connected to the lower accommodating tube 31 and the upper accommodating cavity tube 33. A plurality of circulation pumps 322 are arranged inside the central cavity 321. The circulation pumps 322 pump the water in the lower accommodating tube 31 through a plurality of extension tubes 323. There are two types of circulation pumps 322, one is a forward-set circulation pump 322, which can pump the water at the bottom of the heating chamber 1 upward, and the other is a reverse-set circulation pump 322, which can pump the water at the upper end downward, so that the circulation structure 32 can adapt to different working conditions.

[0069] During the operation of the upper accommodating cavity tube 33, since it needs to form a downward pressure effect on the top pressure seat 42, it requires a certain outward convex action. In the present embodiment, the upper accommodating cavity tube 33 includes an arc-shaped cavity 331 welded to the top of the middle cavity 321, and an inner guide tube 332 is slidably installed on the inner side of the top opening of the arc-shaped cavity 331. When the circulating pump 322 pumps water, the inner guide tube 332 slides to the side away from the arc-shaped cavity 331 and is clamped in the inner installation cavity 41. The inner guide tube 332 is slidably inserted into the arc-shaped cavity 331. When it is necessary to fix the top pressure seat 42, which is also the heating stage, the inner guide tube 332 is pushed out by the circulating pump 322, so that the inner guide tube 332 can form a downward pressure action on the top pressure seat 42. As long as the circulating pump 322 does not stop pumping water, the inner guide tube 332 will not retract.

[0070] After the inner conduit 332 is pushed out, the inner conduit 332 cannot automatically reset even when the reverse circulation pump 322 is started, so the top pressure seat 42 cannot be lifted up and the device cannot be opened. In this regard, a blocking piece 333 is movably provided at the opening of the inner conduit 332 of the embodiment, and the blocking piece 333 is opened when the circulation pump 322 pumps water and is closed after the circulation pump 322 stops pumping. By providing the blocking piece 333 on the inner conduit 332, the blocking piece 333 can block the inner conduit 3 32, the inner conduit 332 can be flushed open by water when water is pumped out from the inside to the outside, and when the inner conduit 332 needs to be reset, the circulating pump 322 no longer pumps water outward, but pumps water downward through the reverse circulating pump 322, and the blocking plate 333 will block the inner conduit 332 due to the absence of external pressure, and the inner conduit 332 will retract after the water between the upper accommodating cavity tube 33 and the middle cavity 321 is drained, thereby removing the restriction of the inner conduit 332 on the top pressure seat 42, allowing the top pressure seat 42 to be reset.

[0071] It should be emphasized that, under normal conditions, the sealing piece 333 will be tightly attached to the opening of the inner conduit 332 due to the setting of a plurality of torsion springs, and will only open when water is pumped in. Once the pressure of the pumped water disappears, it will immediately become closed.

[0072] Although the top pressure seat 42 will be pressed down, it needs to automatically retract into the inner mounting cavity 41 after the downward pressure disappears in order to avoid hindering the opening of the cover plate 39. To this end, the top pressure seat 42 in this embodiment is suspended in the inner mounting cavity 41 by an elastic member 43. In order to allow the top pressure seat 42 to be smoothly pressed down by the inner guide tube 332, both ends of the top pressure seat 42 facing the opening of the inner mounting cavity 41 are chamfered, and the position of the chamfer of the top pressure seat 42 is the inverted truncated table seat 42 connected to the elastic member 43. 1. However, if the walnut is pressed down directly through the entire solid truncated cone seat 421, the water will surge upward and may overflow the outside of the heating chamber 1. In this regard, a plurality of row pins 422 are inserted at the bottom of the truncated cone seat 421 of the present embodiment, and the gap between the row pins 422 and the row pins 422 is smaller than the minimum size of the walnut. The walnut is pressed down by the row pins 422. Preferably, a plurality of small holes are evenly and equidistantly opened on the circumference of the row pins 422, so that water can flow between the row pins 422, thereby improving the uniformity of the heating of the walnut.

[0073] After the mesh frame 11 is placed in the heating chamber 1, if it is directly pressed on the heater 2, it is easy to damage the glass tube 22. Therefore, in this embodiment, a plurality of supporting ribs 12 welded in the heating chamber 1 are provided on the top of the glass tube 22, and the mesh frame 11 is fixed to the top of the supporting ribs 12. The supporting frame formed by the supporting ribs 12 supports the mesh frame 11 to prevent it from damaging the glass tube 22.

[0074] After the boiling is completed, the cover plate 39 is opened by the electric support rod 34, and the mesh frame 11 is lifted by the lifting structure on the gantry. After the water is drained, the walnuts on the mesh frame 11 are put into the low-temperature drying mechanism. The low-temperature drying mechanism specifically includes a drying chamber 10, and a switch door 200 that can be opened and closed is arranged at the upper front end of the drying chamber 10.

[0083] The electric heating film heater 40 includes a group of electric heating film glass plates 401 obliquely installed at the upper front and rear ends of the drying chamber 10, and a heat pump air heater 402 fixedly installed at the lower side of the rear end of the drying chamber 10, the air inlet end of the heat pump air heater 402 is arranged on the outside of the drying chamber 10, and the air outlet end of the heat pump air heater 402 is located in the drying chamber 10 and faces upward to the electric heating film glass plate 401 located at the upper rear end of the drying chamber 10.

[0084] The electric heating film glass plate 401 comprises a glass substrate 4011 and a semiconductor electric heating film 4012 sprayed on the bottom side of the glass substrate 4011.

[0090] A corresponding temperature sensor 1500 is fixedly installed in the drying chamber 10 .

[0091] In another embodiment of the present invention, a method for using the low-temperature drying mechanism described above is provided, comprising the following specific steps:

[0092] S1, the piston rod of the driving cylinder extends to drive the front end of the material blocking frame 501 to move forward to the outside of the drying chamber 10, the driving motor 90 drives the driving shaft 801 to rotate until the driving block 802 is away from the material laying board 502, and the supporting roller 705 on the tightening rod 706 of the vibration assembly 70 is rollingly supported on the bottom side of the material laying board 502, so that the rear side of the material laying board 502 is tilted downward by no more than 5°;

[0093] S2, dumping the material to the front side of the material blocking frame 501 through the external material unloading mechanism, the vibration motor 704 of the vibration assembly 70 is started, and the material is evenly laid backwards under the action of vibration and inclined material guiding;

[0094] S3, after the material is laid, the piston rod of the driving cylinder is reset, and the heat pump air heater 402 and the electric heating film glass plate 401 located at the rear end of the drying chamber 10 start heating respectively. The hot air generated by the heat pump air heater 402 flows through the electric heating film glass plate 401 located at the upper rear end of the drying chamber 10, and then the heat energy is transported into the area where the material is located, thereby drying the material and quickly increasing the drying temperature in the drying chamber;

[0095] S4, after the drying temperature in the drying chamber reaches the set value, the heat pump air heater 402 is turned off, and the electric heating film glass plate 401 located at the front end of the drying chamber 10 is turned on, so as to keep the temperature in the drying chamber 10 within the range required for drying under the premise of low energy consumption, and the far infrared waves generated by the electric heating film glass plate 401 can directly act on the material, thereby improving the drying efficiency of the material;

[0096] S5, after the drying is completed, the piston rod of the driving cylinder extends to drive the front end of the material blocking frame 501 to move forward to the outside of the drying chamber 10, and the driving motor 90 drives the driving shaft 801 to rotate until the driving block 802 is pressed against the material laying plate 502, so that the front side of the material laying plate 502 is tilted downward by no more than 5°;

[0097] S6, open the sealing plate 1100 and start the vibration motor 704 of the vibration assembly 70. Under the effect of vibration and inclined material guiding, the materials are evenly gathered forward and discharged along the discharge port of the material blocking frame 501.

[0098] In fact, the temperature of low-temperature drying is maintained at about 60-80°C. During drying, only the moisture on the surface of the walnuts and part of the moisture inside are removed, and the walnuts cannot be completely dried. Therefore, high-temperature drying is also required after low-temperature drying. The temperature of high-temperature drying is 170-200°C, which can completely dry the walnuts. The high-temperature baking mechanism includes a drying box A20 and a conveyor belt A30 passing through both ends of the drying box A20. The high-temperature baking mechanism also includes: an electric heating component, and a mounting bracket A21 is cantilevered on the top of the inner side of the drying box A20. The electric heating component comprises an electric heating glass plate A31 arranged on the mounting bracket A21, the electric heating glass plate A31 is located above the conveyor belt A30, and the electric heating film A311 is sprayed on the side of the electric heating glass plate A31 facing the conveyor belt A30, and the electric heating films A311 are arranged at intervals; the transmission surface of the conveyor belt A30 is composed of a plurality of chain plates A301, and the left and right sides of the chain plates A301 are both provided with a concave surface A3011 and a convex surface A3012, and the concave surface A3011 and the convex surface A3012 are arranged from top to bottom. The concave surface A3011 of the chain plate A301 and the convex surface A3012 of the adjacent chain plate A301 form a discharge hole that can carry walnuts; a two-way flow guide component includes a lower flow guide A41 arranged on the inner side of the conveyor belt A30, and the two sides of the lower flow guide A41 extend from the two sides of the conveyor belt A30 along the outside of the drying box A20. The lower flow guide A41 inhales and discharges the moist air that overflows downward after the walnuts are baked through the discharge hole, and the gap between the electric heating film A311 and the electric heating film A311 An upper guide member A42 facing the conveyor belt A30 is nested in the partition, and the upper guide member A42 extends downward to 7 to 8 cm from the top surface of the conveyor belt A30. The upper guide member A42 sucks in and discharges the moist air that floats upward after the walnuts are roasted. An equalizing block member A43 is provided on the side of the upper guide member A42 facing the walnut input direction. When the equalizing block member A43 evenly distributes the walnuts to the chain plate A301 and blocks all the leakage holes, the upper guide member A42 and the lower guide member A41 respectively extract the moisture overflowing from the walnuts from the upper and lower ends.

[0099] The mounting bracket A21 in this embodiment is fixed at both ends of the electric heating component, and the electric heating glass plate A31 is suspended on the top of the electric heating component, thereby reducing the difficulty of installing the electric heating glass plate A31 and making it more convenient to replace or clean it.

[0100] An air guide duct is provided on the outer top of the drying box body A20, the air guide duct is connected to an air pump, and the air guide duct is communicated with the upper guide member A42 and the lower guide member A41 respectively.

[0101] Among them, the electric heating glass plate A31 is microcrystalline glass, which is not only resistant to high temperatures, but also has extremely high hardness. It is not easy to have thermal conductivity decay after long-term use. After the electric heating glass plate A31 is powered off, its thermal insulation effect is excellent, and the surface temperature decays very slowly. Energy recovery can also be carried out under some heat recovery conditions.

[0102] In conventional baking equipment, walnuts are often heated by blowing in hot air and then circulating it. After heating, the moisture is mixed with the cooled hot air for reheating. However, since the moisture in the walnuts is completely baked out, the energy consumption for reheating the recovered air is relatively large, which requires the factory to bear extremely high costs. Therefore, the present invention adds an electric heating component, and sets the electric heating component above the conveyor belt A30, so that the electric heating component can heat the walnuts on the conveyor belt A30 in a targeted manner without waiting for the hot air to diffuse, and can heat the walnuts by a double-layer heating method of far-infrared waves and air generated after air heating, so that the walnuts can be baked at high temperature in a short time, thereby achieving the purpose of rapid drying. In actual use, since the electric heating component is cantilevered, the setting height can be adjusted according to specific needs, and the height of the electric heating component can be lowered to reduce the loss of heat energy and far-infrared waves during transmission.

[0103] On the basis of the setting of the electric heating component, the walnuts will still generate moisture during the baking process, and due to the layout of the electric heating component, the heat and moisture are more difficult to be discharged. The traditional exhaust structure is easy to discharge the heat together. In this regard, the present invention adds a two-way guide component. First, a lower guide A41 is set at the bottom of the walnut conveyor belt A30 to suck away the moisture overflowed from the bottom of the walnuts during baking, and at the top position, an upper guide A42 is set down to suck away the moisture overflowed from the top of the walnuts during baking, thereby completing the rapid extraction of moisture in two directions. Since the setting position is directional, Less heat is absorbed during the suction process, and more directly acts on moisture. In order to prevent the stacked walnuts from being too high and unable to evenly discharge moisture up and down, an equalizing member A43 is provided on the side of the upper guide member A42 facing the walnut input direction to evenly flatten the walnuts before suction, so as to prevent moisture from being retained in the middle of the stacked walnuts and affecting the baking effect. The walnuts dried in this embodiment are basically less than 7 cm, and there are no walnuts that are too large. The walnuts are screened before boiling and drying, so as to avoid the phenomenon of unequal processing cycles when processing walnuts of different sizes.

[0104] If the existing conveyor belt is directly used, the lower guide member A41 cannot be set due to the closed setting of the belt surface of the conveyor belt. If the chain plate conveyor belt in the prior art is used, the chain plate conveyor belt has a number of uniform small holes, which will cause the hot air to flow directly downward and be taken away by the lower guide member A41. Therefore, on the basis of the electric heating component and the two-way guide component, the present invention sets the two sides of the chain plate A301 in the present invention as concave and convex surfaces, and leakage holes with a certain gap will appear at the connection position of the chain plate A301. During the normal transmission and drying stage, the walnuts will block the leakage holes to avoid the direct discharge of the hot air generated by the electric heating component, and during the dehumidification. In the stage, when the lower guide piece A41 is started, the moisture of the walnut will be directly discharged through the leakage holes, and the moisture overflowing from the upper end of the walnut will be normally discharged through the upper guide piece A42, so as to achieve the goal of timely discharging moisture from the upper and lower ends and retaining heat in the area between the electric heating component and the walnut, reducing heat loss and energy consumption. However, in fact, the rest of the chain plate A301 is not completely closed. Trough-type holes can also be opened on the chain plate A301. After the walnut is poured in, it will be stuck in the hole to prevent the hot air from escaping directly, and at the same time, it can also facilitate the rapid and large-scale dissipation of moisture at the bottom.

[0105] In the process of setting up some existing top heating structures, the heating structures are set at intervals, so that a dehumidification structure is set in the gap between the heating structures. Although it can achieve the purpose of dehumidification, it is inevitable that a large part of the hot air will be taken away. In this regard, the electric heating glass plate A31 of the present invention includes a plurality of groups of electric heating plates A312 set at intervals, and the electric heating plate A312 is sprayed with an electric heating film A311. The two electric heating plates A312 are connected by a transition plate A313. The lower guide member A41 is sleeved on the outer side of the transition plate A313 and points to the conveyor belt A30. By A312 is connected to the electric heating plate A312 through a transition plate A313, and the transition plate A313 is also made of glass, so as to form a continuous surface on the top surface of the walnut to prevent hot air from overflowing from the top; although the electric heating glass plate A31 forms a continuous surface, the problem of moisture removal still needs to be considered. In this regard, the present invention further proposes that the upper guide member A42 includes a hanging frame A421 connected to the transition plate A313, and a plurality of air inlet cylinders A422 facing the conveyor belt A30 are locked below the hanging frame A421, and a solenoid valve A423 is installed inside the air inlet cylinder A422. , by setting a hanging frame A421 at the position of the transition plate A313, the hanging frame A421 is fixed on the transition plate A313 and extends downward to the top of the conveyor belt A30, and the air inlet tube A422 set on the hanging frame A421 is used to introduce the moisture overflowing from the top. In order to fix the upper guide member A42 and achieve the fixation of the exhaust, the hanging frame A421 is narrow at the top and wide at the bottom. The hanging frame A421 includes a fixed frame A4211 on the outside of the transition plate A313, and a hanging frame A4212 connected to the bottom of the fixed frame A4211, and the inside of the hanging frame A4212 is provided with an inverted An “J”-shaped air guide scoop A4213 is arranged, and the air guide scoop A4213 is communicated with the air inlet cylinder A422. Both ends of the air guide scoop A4213 are extended and fixed to the inner wall of the drying box A20, so that the air inlet cylinder A422 can discharge the inhaled moisture through the air guide scoop A4213, thereby achieving the purpose of dehumidification and retaining most of the hot air. In fact, the “J”-shaped air guide scoop A4213 can not only play the role of air guidance, but also fix the entire sagging frame A421, to prevent the force of the entire sagging frame A421 and the suction generated during suction from all acting on the transition plate A313.

[0106] In the present embodiment, in order to reduce the influence of the air intake cylinder A422 and the air guide hopper A4213 on the hot air during the dehumidification process, and also to improve the baking effect of walnuts and reduce the baking time period, the present embodiment further proposes that the equalizing member A43 includes a vertical baffle A431 locked on the side of the air intake cylinder A422 facing the walnut input direction, and a blocking seat A432 is fixedly connected to the vertical baffle A431, and the outer side surface of the blocking seat A432 is an arc-shaped structure, and the arc-shaped side of the arc-shaped structure is concave toward the side of the vertical baffle A431. By arranging the equalizing member A43 on one side of the air intake cylinder A422, the setting position of the blocking seat A432 in the equalizing member A43 is lower than the air intake cylinder A422, and its arc-shaped position can not only retain the heat and keep the heat in an arched area, but also can separate the heater from the dehumidification area, and can also level the stacked walnuts, thereby achieving a multi-functional setting effect.

[0107] In order to allow a certain amount of heat to be retained, a number of concave sinking holes A4321 are opened on the arc structure of the blocking seat A432. The hot air generated by the heating of the electric heating glass plate A31 is deposited in the sinking holes A4321. Part of the heat of the electric heating glass plate A31 will sink to the bottom here and will not circulate downward, thereby ensuring a basic temperature in the heating chamber and reducing subsequent energy consumption.

[0108] During the operation of the lower guide A41, in order to extract moisture as soon as it is generated to avoid the secondary dispersion of moisture on the walnuts, the present invention further proposes that the lower guide A41 includes a sinking hole A411 located on the inner side of the conveyor belt A30, and exhaust branch pipes A412 for fixing the sinking hole A411 are installed on both sides of the sinking hole A411. The exhaust branch pipe A412 is fixed to the inner wall of the drying box A20, and a plurality of bottom exhaust columns A413 are vertically inserted on the top of the sinking hole A411.
