Description

Technical Field

[0001] The present application relates to the field of microwave processing, and in particular to a continuous production device based on layer-by-layer heating. Background Art

[0002] The traditional heating method is to heat from the surface to the inside through radiation, convection and conduction. In order to avoid excessive temperature gradient, the heating speed is often not too fast. With the continuous improvement of production efficiency and product quality requirements in industries such as food, medicine and chemical industry, microwave heating equipment has gradually been applied to various industrial production processes due to its fast heating speed, high efficiency and uniform heating. At present, material transportation in microwave processing devices mostly adopts conveyor belt transportation, which cannot be produced continuously, has low transportation efficiency and single function. In addition, during the material transportation process, when the material is heated in the microwave electric field, the microwave energy utilization is uneven, the heating efficiency is low, and it is difficult to reflect the advantages of microwave processing.

[0003] Some microwave processing devices use blades to stir the suspended materials in the cavity, so that the materials are evenly distributed in the heating cavity, which improves the uniformity of microwave heating to a certain extent. However, this design cannot transport the heated materials, and valves need to be opened regularly to collect the materials, so continuous production cannot be achieved. At the same time, stirring and heating can only produce local convection in the shallow material layer, and the deep part still cannot fully contact the microwave field, which does not fundamentally solve the problem of heating uniformity. Summary of the invention

[0004] In view of the above problems, the present invention provides a continuous production device based on layer-by-layer heating to solve the problem that current microwave heating cannot take into account both continuous production and heating uniformity.

[0005] The technical solution of the present invention is: A continuous production device based on layer-by-layer heating, the device comprising: A heating chamber is configured to flow material and is in communication with a heat source; Multiple layers of heating plates, each layer of the heating plates being provided with a material opening; A multi-stage toggle device, each stage of the toggle device is arranged on each layer of the heating plate; A driving mechanism, rotatably connected to the multi-stage toggle mechanism; Among them, the material enters the heating cavity, and the driving mechanism drives each level of the toggle and each layer of the heating disk to rotate relative to each other, pushing the material on each layer of the heating disk to rotate and roll, and roll to the next layer of heating disk through the material port, so that the material is evenly heated by the heat transferred from the heat source to the heating cavity, and continuous production is achieved.

[0006] As one of the preferred solutions, the bottom end of each level of the toggle device abuts against the upper surface of each layer of the heating plate.

[0007] As one of the preferred solutions, the top of each stage of the toggle device except the first stage toggle device is arranged in close distance to the lower surface of the heating plate of the upper layer.

[0008] As one of the preferred solutions, the heat transmitted by the heat source includes any one of microwave energy, ultrasonic energy, infrared energy and electrothermal energy.

[0009] As one of the preferred solutions, a plurality of heat sources are provided, and the plurality of heat sources are correspondingly arranged in the heating areas separated by each layer of the heating disk.

[0010] As one of the preferred solutions, the driving mechanism includes a rotating shaft and a driving motor that are connected to each other, and the multi-stage actuators and / or the multi-layer heating plates are arranged on the rotating shaft.

[0011] As one of the preferred solutions, each stage of the toggle device is an arc-shaped plate structure.

[0012] As one of the preferred solutions, the material openings on the multiple layers of the heating plates are staggered.

[0013] As one of the preferred solutions, the multiple stages of the toggle switches are staggered.

[0014] As one of the preferred solutions, the multiple layers of the heating disk and the rotating shaft are configured to be detachably connected or integrally formed.

[0015] Compared with the prior art, this application has the following advantages: The present invention proposes a continuous production equipment based on layer-by-layer heating, the equipment comprising: a heating cavity, which is configured to circulate materials and is connected to a heat source; a multi-layer heating disk, each layer of the heating disk is provided with a material port; a multi-stage toggle, each stage of the toggle is provided on each layer of the heating disk; a driving mechanism, which is rotatably connected to the multi-stage toggle; wherein, when the material enters the heating cavity, the driving mechanism drives each stage of the toggle and each layer of the heating disk to rotate relative to each other, pushing the material on each layer of the heating disk to rotate and tumble, and tumbles to the next layer of the heating disk through the material port, so that the material is evenly heated by the heat transferred from the heat source to the heating cavity, and continuous production is achieved.

[0016] By adopting the technical solution of the present application, a heating plate with a material opening is combined with a toggle. After the material is rotated and scanned by the toggle on each layer of the heating plate, it automatically rolls over and rotates one circle before entering the heating area of ​​the next layer of the heating plate. During the reaction process, the material can be exposed to the thermal field generated by the heat source in all directions, thereby improving heating uniformity, processing efficiency and product quality.

[0017] In the layered heating plate opening design, the material continuously rolls and falls from top to bottom in the cavity, and automatically moves down layer by layer. The tumbling process layer by layer not only allows different parts of the material to contact the heat field in turn and be more fully exposed to the heating area, making the heating effect more sufficient; and the material is constantly pushed to roll and rotate, which effectively avoids the accumulation or adhesion of the material in a certain place and reduces the heating dead corners; at the same time, the automatic downward movement of layers forms a continuous transfer path from top to bottom, without the need for manual or additional conveying mechanism intervention, thereby improving the level of production automation and making it suitable for long-term, high-output continuous production needs.

[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] It should be noted that there are currently various microwave processing devices that improve the uniformity of microwave heating. However, most of them rely on mechanical stirring of blades to promote material mixing. Due to the range and direction of the blades' force, it is easy for some materials to not be fully exposed to the microwave field, resulting in uneven heating. In addition, in order to allow the blades to rotate freely, the blades are directly set in the microwave cavity, and the materials are easy to adhere and accumulate in a corner inside the equipment (such as the bottom of the cavity), especially when processing materials containing moisture, the frequency of cleaning and maintenance is high. In addition, traditional heating equipment requires manual or additional conveying mechanism intervention to promote material flow, and the level of production automation is low, which is particularly unsuitable for long-term, high-output continuous production.

[0023] Therefore, there is an urgent need for a new type of heating equipment that can simultaneously improve the uniformity of material heating, achieve continuous production, and reduce energy consumption, in order to meet the needs of modern industry for high-efficiency, low-cost, and low-maintenance production. Figure 1 As shown, Figure 1 The overall structural diagram of the continuous production equipment based on layer-by-layer heating shown in the present invention is shown, and the internal components are displayed. The present invention proposes a continuous production equipment based on layer-by-layer heating, and the equipment includes: a heating cavity 1, which is configured to circulate materials and is connected to a heat source; a multi-layer heating plate 2, each layer of the heating plate 2 is provided with a material port 3; a multi-stage toggle 4, each stage of the toggle 4 is provided on each layer of the heating plate 2; a driving mechanism, which is rotatably connected with the multi-stage toggle 4; wherein, when the material enters the heating cavity 1, the driving mechanism drives each stage of the toggle 4 and each layer of the heating plate 2 to rotate relative to each other, pushing the material on each layer of the heating plate 2 to rotate and roll, and roll to the next layer of the heating plate 2 through the material port 3, so that the material is evenly heated by the heat transferred from the heat source to the heating cavity 1, and continuous production is achieved.

[0024] Specifically, the heating cavity 1 provides a cavity for accommodating materials and communicating with a heat source, ensuring that the materials can flow in the cavity and be heated by the heat generated by the heat source. The materials include but are not limited to biomass materials such as straw, leaves, orange peels, sawdust, bamboo chips, and tobacco leaves, or other products that need to be heated. The heating cavity 1 can be a cylindrical stainless steel barrel.

[0025] Among them, the heat source may include microwave heating equipment, infrared heating equipment, ultrasonic heating equipment, electric heating equipment, steam heating equipment, induction heating equipment or composite heating equipment, etc.

[0026] For example, electric heating pipes may be installed on the side walls or the bottom of the heating cavity 1, or resistance wires may be provided at the bottom of each layer of the heating plate 2 or the inner wall of the cavity to directly transfer the electric heat energy to the material.

[0027] For example, an infrared lamp can be installed in the heating cavity 1 to heat the material directly through infrared energy through infrared radiation. The infrared lamp can be installed on the top of each layer of heating plate 2 or around the cavity wall.

[0028] For example, a steam layer is designed on the outer wall of the cavity or inside the heating plate 2, or a steam pipe is arranged in the cavity or the heating plate 2, and high-temperature steam energy is provided by an external steam boiler to heat the material.

[0029] For example, an induction coil is arranged on each layer of the heating plate 2 or the outer wall of the cavity or in the cavity, and the heating plate 2 and / or the material are inductively heated by an alternating electromagnetic field. If the material is a magnetic material, the heating plate 2 can be a metal material or a non-metal material. If the material is a non-magnetic material and the heating plate 2 is a metal material, the heating plate 2 absorbs the heat generated by the induction coil to heat the material on the plate.

[0030] Exemplarily, multiple ultrasonic transducers are installed on the bottom, side wall or each heating plate 2 of the cavity to generate ultrasonic energy to heat the material. In this embodiment, the effect of ultrasonic heating usually depends on the uniform vibration of the material, so it is particularly suitable for pushing and turning the material in combination with the relative rotation between the toggle and the heating plate, and the ultrasonic energy has a wider range of action, further enhancing the heating effect.

[0031] Exemplarily, the heating cavity 1 may be connected to a microwave generator, such as a magnetron and a solid-state source. The magnetron may emit microwaves under a high voltage power supply and transfer microwave energy into the cavity.

[0032] In some embodiments, multiple heat sources may be used in combination, such as a combination of microwave and infrared, hot air and electric heating, to ensure optimal heating effect and uniformity of different materials.

[0033] For ease of description, microwave energy is used as an example to illustrate multiple embodiments.

[0034] Specifically, multiple layers of heating plates 2 are arranged at intervals along the central axis of the cavity, and a material port 3 is arranged on each layer of the heating plates 2 for automatic material transportation. The material can enter the next layer from the previous layer through the material port 3 to achieve continuous heating layer by layer. The multi-layer design allows the material to be further heated each time it passes through a layer.

[0035] In this embodiment, the outer edge contour of the heating plate 2 is closely attached to the inner edge contour of the heating cavity 1, so that the material can only enter the lower heating plate 2 from the upper heating plate 2 through the material opening 3. For example, the heating cavity 1 is a stainless steel barrel, and the heating plate 2 is a disc structure, which is a layered disc barrel as a whole.

[0036] In some embodiments, the material of the heating plate 2 can be configured to be supported by a material that can transfer heat and withstand high temperatures, such as stainless steel or aluminum alloy.

[0037] Preferably, the shape and size of the material opening 3 on each layer of the heating plate 2 can allow the material to flow smoothly between each layer. For example, the material opening 3 can be a rectangular bar, a circular hole, a conical opening, an inclined material opening 3, a screen-type material opening 3, etc.

[0038] In some embodiments, the shapes and sizes of the material openings 3 on the multi-layer heating plate 2 may be different, partially the same, or completely the same.

[0039] In some embodiments, one or more material ports 3 may be provided on each layer of the heating plate 2 .

[0040] In some embodiments, the spacing distances between two adjacent layers of heating disks 2 may be the same or different. For example, the spacing distances between two adjacent layers of heating disks 2 may gradually increase.

[0041] The number of layers and size of the heating plate 2 can be determined according to the type of material, production volume requirements, heating efficiency and other requirements.

[0042] Similarly, the design of the material port 3 can be selected according to the material type (such as particles, powder), the humidity of the material, the production process requirements, etc., and this embodiment does not limit this.

[0043] Preferably, each stage of the toggle device 4 is arranged on each layer of the heating disk 2, and the multi-stage toggle device 4 is driven by the driving mechanism to make the material on each layer of the heating disk 2 roll and rotate on the disk surface of that layer.

[0044] In this embodiment, the toggle 4 may include a plate-type toggle 4, which rotates around the central axis and pushes or flips the material so that the material rolls or is evenly distributed on the heating plate 2. The heating plate 2 can rotate relative to the toggle 4, so when the heating plate 2 rotates to the position of the toggle 4, the material is pushed and flipped. The number and layout of the plates can be adjusted according to the type of material to optimize the flipping and heating effect of the material.

[0045] In some embodiments, the plate-type actuator 4 may include a flat plate structure, an arc-shaped plate structure, a wave-shaped plate structure, and the like.

[0046] Preferably, each level of the toggle 4 is an arc-shaped plate structure. The curved surface design of the arc-shaped plate can better push and spread the material when rotating, so that it rolls and rotates on the heating plate 2. The arc-shaped transition toggle 4 can reduce resistance and vibration during the rotation process.

[0047] More preferably, if Figure 1As shown, each stage of the toggle mechanism 4 includes two arc-shaped plates that are symmetrical with respect to the center of the rotation axis, and the whole is in a narrow S-shape.

[0048] In this embodiment, the driving mechanism can be connected to the toggle device 4 by means of motor drive, gear transmission, belt transmission or servo motor to achieve power transmission.

[0049] It can be understood that there is a one-to-one correspondence between the number of multi-stage toggles 4 and the number of multi-layer heating plates 2. The last layer of heating plates 2 is spaced apart from the bottom wall of the heating chamber 1, and a material outlet 7 is provided on the bottom wall of the heating chamber 1. When the material moves down layer by layer to the last layer of heating plates 2, it falls onto the bottom wall of the heating chamber 1 through the material outlet 3, and finally is discharged from the heating chamber 1 through the material outlet 7.

[0050] Preferably, the last layer of heating plate 2 can be the bottom wall surface of the heating cavity 1, that is, a material port 3 and a toggle 4 are arranged on the bottom wall surface of the heating cavity 1, and the material port 3 serves as a material outlet 7. When the material moves down layer by layer to the last layer of heating plate 2 (that is, the bottom wall of the heating cavity 1), it is continued to be pushed by the toggle 4 to be discharged from the heating cavity 1 through the material outlet 7.

[0051] Therefore, the heating disk 2 divides the heating chamber 1 into several heating areas. The material first continuously enters the first layer of heating disk 2. In the heating area, the material is pushed by the first-level toggle 4 on the first layer of heating disk 2. After rotating and tumbling for one circle, the material falls from the first material port 3 to the next layer of heating disk 2. After passing through each layer of heating disk 2 and the toggle 4, the material works together until it is on the last layer of heating disk 2. Finally, the heated material continuously flows out of the heating chamber 1 through the last material port 3 on the last layer of heating disk 2.

[0052] Specifically, a material inlet 6 is provided on the heating cavity 1, and the material inlet 6 is provided in the heating area corresponding to the first layer heating plate 2, so as to ensure that the material entering the heating cavity 1 from the material inlet 6 first enters the first layer heating area.

[0053] Therefore, the open disc is combined with the toggle device 4. After the material is rotated and scanned by the toggle device 4 on each layer of the disc, it automatically rolls over and rotates for one circle before entering the next heating area. During the reaction process, the material can be exposed to the microwave field in all directions, thereby improving the uniformity of microwave heating, processing efficiency and product quality.

[0054] Secondly, with the layered disc opening design, the material continuously rolls and falls from top to bottom in the cavity and automatically moves down layer by layer. The tumbling process layer by layer not only allows different parts of the material to contact the microwave field in turn and be more fully exposed to the heating area, making the heating effect more sufficient; the material is constantly pushed to roll and rotate, which effectively avoids the accumulation or adhesion of the material in a certain place and reduces the heating dead corners; at the same time, the automatic downward movement of layers forms a continuous transfer path from top to bottom, without the need for manual or additional conveying mechanism intervention, which improves the level of production automation and makes it suitable for long-term, high-output continuous production needs.

[0055] Then, when the material falls from the material opening 3 of the upper layer to the lower heating plate 2, the material falls freely due to gravity during the falling process, which not only realizes the material transfer, but also the free falling and tumbling during the falling process makes the material readjust its position in different heating areas so that different surfaces face the microwave field, so the open design further promotes the uniform heating of the material.

[0056] In addition, the material enters the next heating zone after passing through each layer of open discs, which can achieve layered and staged heating treatment. For example, parameters such as microwave power and heating time can be adjusted in different heating zones.

[0057] In summary, the present invention combines layer-by-layer rotational propulsion with microwave processing to form an automated heating process, which takes into account both heating uniformity and continuous production, and is suitable for large-scale high-quality production needs.

[0058] In a further technical solution, the bottom end of each level of the toggle 4 abuts against the upper surface of each layer of the heating plate 2. In this embodiment, the toggle 4 is in zero-distance contact with the heating plate 2, so when the toggle 4 rotates, its bottom end will push and toggle the material on the heating plate 2, so that the material can effectively roll, move, and rotate on the plate surface, and the material on the surface and the material on the bottom layer are alternately mixed and contacted with microwave energy, thereby preventing the material from accumulating or agglomerating on the heating plate 2. At the same time, when the toggle 4 pushes the material to roll and toggle at each layer, it toggle the material to the position of the material port 3, so that the material on each layer can fall to the next layer of the heating plate 2, completing the heating layer by layer.

[0059] In another embodiment, the top of each level of the toggle 4 except the first level toggle 4 is arranged close to the lower surface of the upper layer of the heating plate 2. Since there is no heating plate 2 above the first level toggle 4, the toggle 4 of each level except the first level toggle 4 is optimized. In this embodiment, the height of the toggle 4 is close to the height of the heating area, making the structure more compact. At the same time, when the material is dropped from the upper layer to the lower layer of the heating plate 2, due to the blocking effect of the toggle 4, part of the material is blocked from directly falling from the upper layer to the material opening 3 on the lower layer of the heating plate 2.

[0060] In this embodiment, the height of the toggle 4 is relatively large, so the toggle 4 can toggle the materials in the entire heating area separated by the heating plate 2, which is suitable for efficient processing of large quantities of materials at one time. In this embodiment, when processing large-volume materials, the toggle 4 pushes the materials to tumble and stir the materials at the same time, achieving uniform tumbling heating of large-volume materials, ensuring heating uniformity and fluidity, while reducing energy consumption, and is more suitable for efficient and continuous large-volume processing.

[0061] In some preferred embodiments, the top of the toggle 4 does not abut against the lower surface of the upper heating plate 2, so the toggle 4 will not block the material opening 3 on the heating plate 2 at a certain position at a certain moment during the rotation process.

[0062] It can be known that the input and output flow rates of the material can be designed so that the thickness of the material is just pushed by the paddle 4 to perform a tumbling motion, so that different parts of all the materials are fully exposed to the microwave field.

[0063] For example, when the thickness of the material when it falls onto the heating plate 2 is much smaller than the height of the toggle 4, the toggle 4 can more easily drive the material to roll and rotate as a whole. The tumbling motion allows the material to continuously change direction during microwave heating, so that each part can be evenly exposed to the microwave field, thereby obtaining a more uniform heating effect. In this embodiment, the height of the toggle 4 can be set to be relatively small, in the shape of a strip plate.

[0064] For example, when the thickness of the material falling onto the heating plate 2 is slightly less than or close to the height of the toggle 4, the overall tumbling is reduced, and the toggle 4 drives the material to tumble and stir. In this embodiment, the height of the toggle 4 can be set higher and in the shape of a panel.

[0065] In another embodiment, in order to achieve uniform heating of the material in the heating cavity 1, a plurality of microwave feed ports 5 are provided on the cavity wall of the heating cavity 1, and each of the microwave feed ports 5 is used to connect to a microwave generator.

[0066] In this embodiment, at least one microwave feed port 5 may be in the shape of a rectangular hole, a circle or other shapes, or a combination of multiple shapes. The microwave generator is used to generate microwave energy and transmit the microwave energy to the heating cavity 1 through the microwave feed port 5. The microwave generator may be a magnetron, a solid-state source, etc.

[0067] Preferably, the plurality of microwave feed ports 5 are correspondingly arranged in the heating areas separated by each layer of the heating plate 2. In this embodiment, each layer of the heating area corresponds to one or more microwave feed ports 5, so that the microwave energy directly acts on the material in each layer, so that the microwave energy is evenly distributed, and the heating uniformity is further improved.

[0068] In some embodiments, a plurality of microwave feed ports 5 are evenly spaced along the circumference of each layer of heating area.

[0069] In some embodiments, the microwave feed ports 5 located in two adjacent layers of heating regions are staggered, that is, the connecting line of the microwave feed ports 5 in two adjacent layers of heating regions is not a straight line.

[0070] For example, from top to bottom, a microwave feed port 5 is arranged on the left side of the first heating area, a microwave feed port 5 is arranged on the right side of the second heating area, a microwave feed port 5 is arranged on the front side of the third heating area, and a microwave feed port 5 is arranged on the back side of the fourth heating area.

[0071] For another example, a microwave feed port 5 is provided on the left and right sides of the first layer heating area, a microwave feed port 5 is provided on the front and back sides of the second layer heating area, the third layer is the same as the first layer, the fourth layer is the same as the second layer, and so on.

[0072] In some embodiments, the microwave feed ports 5 located in two adjacent heating regions are arranged in parallel. Figure 1 As shown, the positions of the microwave feed ports 5 in the upper and lower heating regions are aligned, and two radially symmetrical microwave feed ports 5 are arranged in each heating region.

[0073] Of course, the number and position of the microwave feed ports 5 can be flexibly adjusted according to the type of material and production purpose.

[0074] In another technical solution, the driving mechanism includes a rotating shaft and a driving motor connected to each other, and the multi-stage toggle 4 and / or the multi-layer heating plate 2 are arranged on the rotating shaft. In this embodiment, the rotating shaft passes through each layer of the heating plate 2 from top to bottom and is connected to the driving motor installed on the outer side of the bottom wall of the heating chamber 1. The multi-stage toggle 4 is fixedly installed on the rotating shaft at equal distances from top to bottom, and the multi-stage toggle 4 is driven by the driving motor to achieve synchronous rotation.

[0075] The toggling force of the toggling device 4 can be designed, and the toggling force and tumbling frequency of the material can be precisely controlled by changing the speed of the motor or adjusting the shape of its bottom end.

[0076] In this embodiment, the rotation axis coincides with the central axis of the heating chamber 1 .

[0077] It can be known that the relative rotation of each level of the toggle 4 and each layer of the heating plate 2 can be achieved through the matching relationship with the rotating shaft. When the toggle 4 rotates relative to the heating plate 2, the toggle 4 is fixedly connected to the rotating shaft to rotate synchronously with the rotating shaft (for example, each toggle 4 is tightly connected to the rotating shaft through a fastener (such as a screw, a buckle, etc.)). At this time, the heating plate 2 can be fixed on the wall surface of the heating cavity 1, and the rotating shaft passes through the opening of the heating plate 2, but is not connected to the rotating shaft.

[0078] In some embodiments, the heating plate 2 may also be fixed in the heating chamber 1 by a supporting structure (such as a frame or a bracket) so that it does not rotate with the rotating shaft.

[0079] In some embodiments, the heating plate 2 may also be connected to the rotating shaft via a sliding bearing, so that the rotating shaft can drive the toggle 4 to rotate synchronously without driving the heating plate 2 to rotate.

[0080] Similarly, when the heating plate 2 rotates relative to the toggle 4, the heating plate 2 is fixedly connected to the rotating shaft to rotate synchronously with the rotating shaft. The toggle 4 may refer to the above arrangement.

[0081] In some embodiments, the heating disc 2 and the toggle 4 can be set to rotate at different speeds to push the material. For example, there are two rotating shafts, one shaft drives the heating disc 2, and the other shaft drives the toggle 4. By controlling the rotation speeds of the two shafts respectively, the heating disc 2 and the toggle 4 rotate asynchronously, so as to achieve the effect of tumbling and pushing the material. The two shafts are respectively connected to different drive motors, and the relative rotation speeds of the heating disc 2 and the toggle 4 are controlled by adjusting the rotation speeds of the motors.

[0082] In some embodiments, a gear differential device can be designed between the rotating shaft and the heating plate 2 and the toggle 4. A gear can be installed on the rotating shaft to engage with the heating plate 2 to drive the heating plate 2, and another gear can be engaged with the toggle 4 to drive the toggle 4. Through the differential gear set, the heating plate 2 and the toggle 4 can rotate asynchronously.

[0083] In some embodiments, the rotation speed of each layer of the heating plate 2 or each level of the toggle 4 can be set to be different, which can be achieved through a multi-axis independent drive system or a graded gear transmission system.

[0084] As a further illustration of this embodiment, the plurality of heating discs 2 and the rotating shaft are configured to be detachably connected, or the plurality of heating discs and the rotating shaft are configured to be integrally formed. The rotating shaft and the heating disc 2 may be designed to be separated, and the plurality of heating discs 2 are combined to form a cavity having a plurality of heating areas. The rotating shaft and the heating disc 2 may be designed to be integral, and the heating cavity 1 may be divided into a plurality of heating areas after the integral structure is installed in the cavity.

[0085] It can be known that the specific connection method between the rotating shaft and the heating plate 2 can refer to the above matching relationship.

[0086] In this embodiment, the multi-layer heating disc 2 is a separated structure, the upper layer of the heating disc 2 is not connected to the lower layer of the heating disc 2, and the cavity is divided into separate cylindrical heating areas connected through the material port 3. Similarly, the multi-layer heating disc 2 is an integrated structure, spirally rising around the axis of the rotating shaft, and the continuous heating discs 2 are spirally shaped as a whole, dividing the cavity into heating areas that are connected as a whole, and connected up and down through the material port 3.

[0087] In another design, the material openings 3 on the multiple layers of the heating plates 2 are staggered. In this solution, the staggered material openings 3 ensure that the material does not fall directly from the upper layer to the next layer, or the material falls to the last layer too quickly during the heating process. Therefore, the staggered material openings 3 fall layer by layer through the plate surface of each layer and the toggle 4, and the material has a longer residence time on each layer of the plate surface, so that the material is fully rolled at different levels, and the layered heating is more uniform.

[0088] For example, see Figure 2 As shown, Figure 2 The principle state diagram of the multi-stage toggle and multi-layer heating plate is shown.

[0089] From top to bottom, the material openings of the first layer heating plate 2, the second layer heating plate 2 and the third layer heating plate 2 are equally divided at 360°.

[0090] In another design, the multiple levels of the toggle devices 4 are staggered. In this solution, the staggered arrangement of the toggle devices 4 forms different rotation trajectories during the rotation process, changing the flow path of the material on different disks, so that the material rolls and moves with different trajectories on each layer of the disk, increasing the overall rolling effect, thereby achieving all-round and uniform heating.

[0091] Exemplarily, from top to bottom, the first-stage toggle 4 , the second-stage toggle 4 , and the third-stage toggle 4 are respectively in different positions when in a stationary state, and the toggle 4 of two adjacent layers are perpendicular to each other.

[0092] Exemplarily, the material opening 3 on the corresponding heating plate 2 and the toggle 4 in a stationary state can be arranged opposite to each other.

[0093] In another design, the material inlet 6 and the material outlet 7 are staggered on the heating cavity 1. In this solution, the staggered arrangement of the material inlet 6 and the outlet ensures that the material does not flow to the outlet immediately after entering, extending the heating path of the material, passing through each layer of the disk from the inlet to the outlet in sequence, avoiding the material from falling directly due to gravity and missing the heating area, so that it can obtain more sufficient microwave energy.

[0094] In summary, this solution proposes a continuous production equipment based on layer-by-layer heating, aiming to solve the problems of uneven heating of materials and inability to produce continuously during traditional microwave heating. The equipment achieves rotation, tumbling and uniform heating of materials during layer-by-layer heating through the coordinated work of a multi-layer open heating plate 2, a multi-stage toggle 4 and a driving mechanism, thereby improving production efficiency and heating effect. This solution is suitable for industrial production scenarios that require continuous heating, such as food processing, heating of chemical raw materials, and drying treatment. In particular, in applications that require microwave heating, such as food drying, grain processing, and preheating of chemical particles, the equipment can improve the energy efficiency and uniformity of the microwave heating process, and meet the continuous production needs of efficient and uniform heating in modern industry.
