Description
Technical Field
[0001] This utility model relates to the field of baking equipment technology, and in particular to a constant temperature fermentation and baking equipment. Background Technology
[0002] Baking equipment is a specialized device that heats food using a heat source. It is widely used in the processing of meat products, fruits and vegetables, traditional Chinese medicine, and industrial materials. For some materials, the baking equipment needs to maintain them within a suitable range during processing to complete the fermentation process.
[0003] Chinese utility model patent CN218869320U discloses a tea roasting and fermentation device, including a roasting oven. A servo motor is fixedly connected to the top of the roasting oven, and a long shaft is fixedly connected to the bottom of the servo motor. An auger blade is sleeved on the outer side of the bottom of the long shaft, and an auger tube is sleeved on the outer side of the auger blade. The servo motor drives the long shaft to rotate, which in turn drives the auger blade to rotate. The rotation of the auger blade causes the tea leaves at the bottom of the roasting oven to move upwards to the top of the auger tube and fall out.
[0004] Regarding the aforementioned technologies, the inventors believe the following drawbacks exist: During operation, the device relies on the rotational motion of the auger blades to convey materials upwards from the bottom. However, in actual operation, some materials are prone to jamming within the baking oven. After the auger blades carry away the bottom material, subsequent materials cannot move normally due to jamming, thus forming material cavities inside the equipment, forcing the interruption of subsequent material conveying. Utility Model Content
[0005] To address the aforementioned problems, this invention provides a constant temperature fermentation and baking device.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a constant temperature fermentation and baking device, including a frame, a screw conveyor vertically arranged on the frame, a rotating shaft vertically rotatably arranged inside the screw conveyor, a drive motor vertically arranged at the top of the screw conveyor, the output shaft of the drive motor pointing downward and connected to the upper end of the rotating shaft, screw conveyor blades arranged on the rotating shaft, a feed inlet at the lower part of the screw conveyor and a discharge outlet at the upper part, a feed hopper arranged on the outer wall of the screw conveyor at the feed inlet, a baking box connected to the feed hopper also arranged on the frame, a swing plate rotatably arranged at the lower part of the baking box, a rotating shaft horizontally rotatably arranged below the swing plate inside the baking box, two cams fixedly sleeved on the rotating shaft, the wheel surface of the cams contacting the bottom surface of the swing plate, and a linkage component that drives the rotating shaft to rotate when the rotating shaft rotates at the bottom of the screw conveyor.
[0007] By adopting the above technical solution, an auger drum, drive motor, auger blades, baking oven, swing plate, and linkage assembly are set up. Material in the baking oven accumulates on the swing plate and slides into the feed hopper before entering the auger drum. The drive motor drives the rotating shaft and auger blades to rotate, conveying the material upwards from the auger drum. The material is then discharged from the outlet, falling onto the upper layer of material. This cycle ensures uniform baking. When the rotating shaft rotates, the linkage assembly drives the rotating shaft and cam to rotate. When the cam's protruding part contacts the bottom surface of the swing plate, it pushes the swing plate upwards. When the cam's protruding part separates from the swing plate, the swing plate swings downwards to reset. The swing plate continuously performs regular reciprocating motion, vibrating the material on its upper side, effectively preventing material accumulation and blockage in the baking oven. This ensures that material can smoothly enter the feed hopper, thereby guaranteeing stable material conveying by the auger blades and preventing conveying interruptions.
[0008] Furthermore, the linkage component includes a mounting base disposed on the outer wall of the auger cylinder, the lower end of the rotating shaft passing through the bottom of the auger cylinder and provided with a large bevel gear, a mounting shaft horizontally rotatably disposed on the mounting base, a small bevel gear disposed at one end of the mounting shaft and a first sprocket disposed at the other end, the small bevel gear meshing with the large bevel gear, a second sprocket fixedly sleeved on the rotating shaft, and the second sprocket being connected to the first sprocket by a chain.
[0009] By adopting the above technical solution, a mounting base, a large bevel gear, a small bevel gear, a first sprocket, a second sprocket, and a chain are set up. The rotation of the rotating shaft drives the large bevel gear to rotate, thereby driving the small bevel gear, the mounting shaft, and the first sprocket to rotate. Since the second sprocket is connected to the first sprocket through a chain, the rotation of the first sprocket drives the second sprocket and the rotating shaft to rotate.
[0010] Furthermore, a fixed shaft is horizontally arranged on the side of the baking oven near the feed hopper, and the swing plate is rotatably connected to the fixed shaft. The lower part of the baking oven away from the fixed shaft is an arc-shaped plate, and the arc of the arc-shaped plate coincides with the axis of the fixed shaft. The side of the swing plate away from the feed hopper is in contact with the arc-shaped plate.
[0011] By adopting the above technical solution, a fixed shaft and an arc-shaped plate are set to ensure that the swing plate can swing, and that the material will not pass through the swing plate during the swing.
[0012] Furthermore, the bottom of the baking oven is provided with an installation plate, and the installation plate is provided with two arc-shaped tubes. An arc-shaped rod is slidably installed inside the arc-shaped tubes, with its top end connected to the bottom of the swing plate. The arc shape of the arc-shaped rod and the arc-shaped tubes coincides with the axis of the fixed shaft. A return spring is sleeved on the rod body of the arc-shaped rod located between the swing plate and the arc-shaped tubes.
[0013] By adopting the above technical solution, which includes a mounting plate, an arc-shaped tube, an arc-shaped rod, and a return spring, the arc-shaped rod slides within the arc-shaped tube when the swing plate swings, ensuring the stability of the swing plate's movement. Furthermore, when the swing plate swings upwards, the return spring is stretched. When the protruding part of the cam separates from the bottom surface of the swing plate, the return spring loses its restraint, pulling the swing plate to its quick return, thus improving its return efficiency and ensuring continuous and stable swinging of the swing plate.
[0014] Furthermore, heating wires are provided on both sides of the outer wall of the baking oven, and two heat insulation covers are also provided on the outer wall of the baking oven, with the heating wires located inside the corresponding heat insulation covers.
[0015] By adopting the above technical solution, a heating wire and a heat insulation cover are installed. The heating wire heats up when energized, heating the baking oven and thus baking the materials inside. The heat insulation cover reduces heat loss from the heating wire, minimizing energy consumption.
[0016] Furthermore, the rack is also equipped with an insulated box, and the baking oven is located inside the insulated box.
[0017] By adopting the above technical solutions and setting up an insulated box, the insulated box can not only effectively block the heat exchange between the baking oven and the external environment and lock in the heat inside the box, but also extend the heat preservation time of the materials after the equipment stops running, significantly reduce the frequency of repeated heating of the equipment, reduce energy consumption, and ensure the stability and continuity of the baking quality of the materials while achieving energy saving and consumption reduction.
[0018] Furthermore, the feed hopper is provided with an outlet, and two fixed blocks are spaced apart at the bottom of the feed hopper. A connecting shaft is rotatably arranged between the two fixed blocks, and a sealing plate is provided on the connecting shaft. A fixed seat is provided on one side of the feed hopper, and a power motor is horizontally arranged on the fixed seat. The output shaft of the power motor passes through the fixed seat and is connected to the end of the connecting shaft.
[0019] By adopting the above technical solution, a discharge port, a connecting shaft, and a power motor are set up. When the baking is finished and the material needs to be discharged, the power motor drives the connecting shaft to rotate, which in turn drives the sealing plate to rotate. The discharge port is unobstructed, and the material is discharged from the discharge port.
[0020] Furthermore, the oven has an inlet at the top, and a top cover is hinged to the inlet at the top of the oven.
[0021] In summary, this utility model has the following beneficial effects: This application includes an auger cylinder, a drive motor, auger blades, a baking oven, a swing plate, and a linkage assembly. Material in the baking oven accumulates on the swing plate and slides into the feed hopper before entering the auger cylinder. The drive motor drives the rotating shaft and auger blades to rotate, conveying the material upwards from the auger cylinder. The material is then discharged from the outlet, falling onto the upper layer of material. This cycle ensures uniform baking. When the rotating shaft rotates, the linkage assembly drives the rotating shaft and cam to rotate. When the protruding part of the cam contacts the bottom surface of the swing plate, it pushes the swing plate upwards. When the protruding part of the cam separates from the swing plate, the swing plate swings downwards to reset. The swing plate continuously performs regular reciprocating motion, vibrating the material on its upper side, effectively preventing material accumulation and blockage in the baking oven, ensuring smooth material entry into the feed hopper, and thus ensuring stable material conveying by the auger blades, avoiding conveying interruptions.

[0030] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0031] like Figure 1-7As shown in the embodiment of this application, a constant temperature fermentation and baking device is disclosed, including a frame 10, an auger cylinder 20, a drive motor 22, auger blades 23, a baking oven 30, a swing plate 31, and a linkage assembly 40. The auger cylinder 20 is vertically mounted on the frame 10, and a rotating shaft 21 is vertically rotatable inside the auger cylinder 20. The drive motor 22 is vertically mounted on the top of the auger cylinder 20, and the output shaft of the drive motor 22 is downward and connected to the upper end of the rotating shaft 21. The auger blades 23 are mounted on the rotating shaft 21. A feed inlet 24 is opened at the lower part of the auger cylinder 20, and an upper... The auger cylinder 20 has a discharge port 25. A feed hopper 26 is located on the outer wall of the auger cylinder 20 at the feed inlet 24. The baking oven 30 is mounted on the frame 10 and connected to the feed hopper 26. A swing plate 31 is rotatably mounted inside the lower part of the baking oven 30. A rotating shaft 32 is horizontally mounted inside the baking oven 30 below the swing plate 31. Two cams 33 are fixedly mounted on the rotating shaft 32, with the wheel surfaces of the cams 33 contacting the bottom surface of the swing plate 31. A linkage assembly 40 is located at the bottom of the auger cylinder 20 and is used to drive the rotating shaft 32 to rotate when the rotating shaft 21 rotates. The material inside the baking oven 30 accumulates on the swing plate 31 and slides into the feed hopper 26 into the auger cylinder 20. The drive motor 22 drives the rotating shaft 21 and the auger blades 23 to rotate, conveying the material inside the auger cylinder 20 upwards. The material is then discharged from the discharge port 25, falling onto the upper layer of material. This cycle ensures the uniformity of baking and fermentation. When the rotating shaft 21 rotates, the linkage component 40 drives the rotating shaft 32 and the cam 33 to rotate. When the protruding part of the cam 33 contacts the bottom surface of the swing plate 31, it pushes the swing plate 31 to swing upward. When the protruding part of the cam 33 separates from the swing plate 31, the swing plate 31 swings downward to reset. The swing plate 31 continues to perform regular reciprocating motion, which effectively prevents the material from accumulating and blocking in the baking oven 30, and ensures that the material can smoothly enter the feed hopper 26, thereby ensuring that the auger blades 23 can stably convey the material and avoid conveying interruption.
[0032] Specifically, the baking oven 30 has an inlet at the top, and a top cover 38 is hinged to the inlet. When materials need to be added to the baking oven 30, the top cover 38 is opened, and the materials are fed into the baking oven 30 through the inlet. After feeding, the top cover 38 is closed, blocking the inlet and preventing heat loss during baking. The feeding hopper 26 has an outlet. Two fixing blocks 60 are spaced apart at the bottom of the feeding hopper 26, and a connecting shaft 61 is rotatably connected between the two fixing blocks 60. A sealing plate 62 for blocking the outlet is installed on the connecting shaft 61. A fixed seat is installed on one side of the feeding hopper 26, and a power motor 63 is horizontally mounted on the fixed seat. The output shaft of the power motor 63 passes through the fixed seat and is connected to the end of the connecting shaft 61. During baking, the sealing plate 62 blocks the outlet to prevent materials from falling out. When it is time to discharge materials after baking, the power motor 63 drives the connecting shaft 61 to rotate, which in turn drives the sealing plate 62 to rotate, removing the obstruction at the outlet and allowing the materials to be discharged.
[0033] During setup, heating wires 36 are installed on both sides of the outer wall of the baking oven 30. The heating wires 36 operate based on the thermal effect of electric current; that is, electrical energy is converted into heat energy when current passes through a high-resistance material. When energized, the heating wires 36 heat up, heating the baking oven 30 and thus baking the materials inside. Two heat insulation covers 37 are also installed on the outer wall of the baking oven 30, with the heating wires 36 located within their respective covers. The heat insulation covers 37 reduce heat loss from the heating wires 36, minimizing energy consumption. An insulation box 11 is also installed on the frame 10, with the baking oven 30 located inside. The insulation box 11 not only effectively blocks heat exchange between the baking oven 30 and the external environment, locking in heat, but also extends the heat preservation time of the materials after the equipment stops operating, significantly reducing the frequency of repeated heating and energy consumption. This achieves energy saving and consumption reduction while ensuring the stability and consistency of the baked material quality.
[0034] In a specific configuration, the linkage assembly 40 includes a mounting base 41 disposed on the outer wall of the auger cylinder 20. The lower end of the rotating shaft 21 passes through the bottom of the auger cylinder 20 and is equipped with a large bevel gear 42. The rotation of the rotating shaft 21 drives the large bevel gear 42 to rotate. A mounting shaft 43 is horizontally rotatably mounted on the mounting base 41. One end of the mounting shaft 43 is equipped with a small bevel gear 44, and the other end is equipped with a first sprocket 45. The small bevel gear 44 meshes with the large bevel gear 42. The rotation of the large bevel gear 42 drives the small bevel gear 44, the mounting shaft 43, and the first sprocket 45 to rotate. A second sprocket 46 is fixedly sleeved on the rotating shaft 32. The second sprocket 46 is connected to the first sprocket 45 through a chain 47, so that when the first sprocket 45 rotates, it drives the second sprocket 46 and the rotating shaft 32 to rotate.
[0035] A fixed shaft 34 is horizontally installed on the side of the baking oven 30 near the feed hopper 26. A swing plate 31 is rotatably connected to the fixed shaft 34. An arc-shaped plate 35 is located at the bottom of the baking oven 30, away from the fixed shaft 34. The arc of the arc-shaped plate 35 coincides with the axis of the fixed shaft 34. The side of the swing plate 31 away from the feed hopper 26 contacts the arc-shaped plate 35, ensuring that the swing plate 31 can swing without material passing through it. A mounting plate 50 is installed at the bottom of the baking oven 30. Two arc-shaped tubes 51 are installed on the mounting plate 50. An arc-shaped rod 52, whose top end connects to the bottom of the swing plate 31, slides within the arc-shaped tubes 51. The arc-shaped rod 52 and the arc-shaped tubes 51 both coincide with the axis of the fixed shaft 34. When the swing plate 31 swings, the arc-shaped rod 52 slides within the arc-shaped tubes 51, ensuring the stability of the swing plate 31's movement. A return spring 53 is fitted onto the rod 52 located between the swing plate 31 and the arc-shaped tubes 51. When the swing plate 31 swings upward, the return spring 53 is stretched. When the protruding part of the cam 33 separates from the bottom surface of the swing plate 31, the return spring 53 loses its restraint and pulls the swing plate 31 to quickly return to its original position, improving its return efficiency and ensuring that the swing plate 31 can swing continuously and stably. A rubber sheet is provided between the swing plate 31 and the feed hopper 26. One side of the rubber sheet is connected to the top surface of the swing plate 31, and the other side is connected to the inner wall of the feed hopper 26 to prevent material from falling between the swing plate 31 and the feed hopper 26 (the rubber sheet is not shown in the figure).
[0036] The operating principle of the constant temperature fermentation and baking equipment in this embodiment is as follows: Material is fed into the baking chamber 30 through the inlet. The material accumulates on the swing plate 31 and slides into the feed hopper 26 and into the auger drum 20. The heating wire 36 is energized and heats the baking chamber 30. The drive motor 22 is activated to drive the rotating shaft 21 and the auger blades 23 to rotate, conveying the material in the auger drum 20 upwards. The material is then discharged from the outlet 25 and falls onto the upper layer of material. When the rotating shaft 21 rotates, it drives the large bevel gear 42 to rotate, thereby driving the small bevel gear 44, mounting shaft 43, first sprocket 45, second sprocket 46, rotating shaft 32, and cam 33 to rotate. With the cooperation of the return spring 53, the swing plate 31 is pushed upwards, vibrating the material on its upper side. This effectively prevents material from accumulating and clogging in the baking chamber 30, ensuring that the material can smoothly enter the feed hopper 26, thus ensuring that the auger blades 23 can stably convey the material and avoid interruptions in the conveying process.
[0037] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
