Description

Technical Field

[0001] This invention belongs to the technical field of food steaming equipment, specifically relating to a cooking conveyor belt. Background Technology

[0002] In the food processing industry, especially for the continuous cooking of granular materials such as rice and millet, steaming machines are one of the core pieces of equipment. Various automated continuous steaming machines have been developed to achieve uniform cooking of materials and improve production efficiency.

[0003] For example, Chinese invention patent CN105212690B discloses a food steaming machine, which includes a steaming section, a movable conveying device, and a leveler. This equipment conveys materials from the inlet to the steaming chamber via the conveying device and steams the materials using steam. This design further optimizes the steam supply method by setting a first air vent and a second air vent to achieve bottom-up or simultaneous top-down steaming of the materials, attempting to improve steaming uniformity. In addition, the equipment uses a leveler to flatten the materials to control their thickness.

[0004] Based on the aforementioned technical solutions, utility model patent CN223695556U proposes an intelligent automatic continuous steaming machine. This equipment is equipped with a steam collection hood and a heat exchanger in the feeding and discharging modules, respectively, utilizing the escaping steam to preheat the water supply, thus achieving energy recovery and utilization. More importantly, this solution explicitly establishes an independent water supply system, distributed vertically within the steaming chamber. Through a top-down water spraying method, moisture is replenished to the material during the steaming process, aiming to solve the "undercooked" problem caused by excessive moisture loss from the surface of the rice grains during steaming, thereby improving the taste of the cooked rice.

[0005] However, although the aforementioned existing technologies have improved the steaming effect to some extent through bidirectional steam supply and the addition of a water replenishment system, they still have limitations in practical applications. The core problem lies in the fact that the material remains in a static, flat state on the conveying device. Even with thickness control via a leveler, the material layer maintains a relatively dense structure. Both bottom-up steam penetration and top-down water replenishment must overcome the resistance inherent in the material layer itself. Steam struggles to penetrate evenly along the material's thickness, and moisture tends to accumulate on the surface rather than penetrate deeply, potentially leading to uneven cooking, undercooked interiors, or excessively wet surfaces during steaming. This is especially critical in the rice gelatinization stage, where the starch's water absorption, expansion, and gelatinization require highly uniform action of both steam and water, a requirement that the static, flat structure of existing equipment cannot meet. Therefore, breaking the static, flat state of the material during steaming and actively guiding steam and water to penetrate evenly within the material layer remains a pressing technical challenge in this field. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides a cooking conveyor belt. This steaming machine aims to solve the technical problem of uneven steam and water penetration caused by the static flat spreading of materials in existing steaming machines, which easily leads to undercooked materials.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A curing conveyor belt includes a body, a mesh belt conveyor device, and a supporting material distribution device; the mesh belt conveyor device is installed inside the body, and openings are provided on both sides of the body. The interior of the body is a steam chamber, and steam pipes are provided inside the body; a material distribution device is provided at one side opening of the body, and a discharge hopper is provided at the other side opening of the body. The supporting material distribution device includes a supporting bracket and a material distribution rod. The supporting bracket is slidably connected to the machine body, and the machine body is provided with a drive mechanism connected to the supporting bracket. The supporting bracket contacts the upper mesh belt of the mesh belt conveyor and lifts the upper mesh belt through the supporting bracket. The support bracket is equipped with a steam spray pipe; a support plate is fixedly connected to the support bracket, and the material distribution rod is slidably connected to the support plate. The support plate is equipped with a corresponding first sliding groove, and a first limiting protrusion is provided in the first sliding groove; a support spring is provided between the material distribution rod and the support plate, and the material distribution rod is equipped with several material distribution teeth; a water replenishment and cleaning spray pipe is provided on the support plate. A first inclined plate is fixedly connected inside the machine body, and a first push rod is provided on the material distribution rod to cooperate with the first inclined plate. When the first push rod contacts the first inclined plate and moves along the first inclined plate, the distance between the material distribution rod and the material distribution teeth and the upper mesh belt can be changed. When the first push rod separates from the first inclined plate, the support plate is limited by the first limiting protrusion.

[0008] The support plate is slidably connected to the water replenishment and cleaning spray pipe. The support plate is provided with a corresponding second sliding groove, and a second limiting protrusion is provided in the second sliding groove. A first spring is provided between the water replenishment and cleaning spray pipe and the support plate. A second inclined plate is fixedly connected to the machine body. A second push rod that cooperates with the second inclined plate is provided on the material distribution rod of the water replenishment and cleaning spray pipe. The inclination of the first inclined plate and the second inclined plate are opposite and are staggered.

[0009] The machine body is equipped with a water supply spray pipe assembly, which is located above the upper mesh belt; the machine body is also equipped with a cleaning pipe, which is located above the lower mesh belt of the mesh belt conveyor.

[0010] The lower end of the material separating teeth is a pointed part, and the material separating teeth are provided with a material separating inclined surface; the material separating teeth are spaced apart.

[0011] The support bracket includes a support rod and a semi-circular top plate. There are at least two semi-circular top plates, which are fixedly connected to each other by the support rod.

[0012] The drive mechanism includes a drive screw and a drive motor. The drive screw is rotatably connected to the machine body, and the support bracket is threadedly connected to the drive screw. The housing of the drive motor is fixedly connected to the machine body. Both the output shaft of the drive motor and the drive screw are fixedly connected to transmission wheels, and the two transmission wheels are driven by a belt or chain.

[0013] Both sides of the machine body have openings for waste heat recovery devices; the waste heat recovery devices include a recovery hood, a suction hood, and a heat exchange pipe; the recovery hood is connected to the steam chamber and fixedly connected to the machine body; the suction hood is located above the recovery hood; the heat exchange pipe is installed inside the recovery hood.

[0014] The fabric feeding device includes a fabric hopper and an adjusting component, which adjusts the distance between the bottom of the fabric hopper and the upper mesh belt; the two sides of the fabric hopper are connected to the machine body through connecting components; the fabric hopper is located above the upper mesh belt. The connecting assembly includes a connecting column and a connecting plate. The connecting plate is fixedly connected to the fabric hopper. The lower end of the connecting column is fixedly connected to the machine body. The connecting plate and the connecting column are slidably connected. A second spring that cooperates with the connecting plate is provided on the connecting column.

[0015] The adjustment assembly includes an adjustment shaft and an adjustment wheel, with the adjustment wheel fixedly connected to the adjustment shaft; both ends of the adjustment shaft pass through the fabric hopper and are rotatably connected to the machine body, and the fabric hopper is provided with corresponding waist-shaped through holes; The adjusting wheel is provided with at least two supporting planes, and each supporting plane is at a different vertical distance from the center of the adjusting shaft; the supporting planes contact the lower surface of the connecting plate and support the connecting plate.

[0016] A pair of feeding ramps are fixedly connected inside the fabric hopper, and there is a gap between the bottoms of the pair of feeding ramps to form a feeding port; An adjusting block is slidably connected inside the fabric hopper, and the adjusting block is located below the material discharge port; the adjusting block is rotatably connected to the adjusting shaft.

[0017] Compared with the prior art, the beneficial effects of this invention are: This invention utilizes a movable support and distribution device to partially lift the upper conveyor belt using support brackets, causing the originally flat material layer to undulate during transport. As the material passes over the top of the support brackets, the upper gaps naturally increase, even forming cracks, significantly reducing the resistance to steam and water penetration. This allows the material to come into more uniform contact with steam and moisture, effectively improving the problem of undercooked material caused by penetration difficulties and ensuring consistent cooking levels throughout the material.

[0018] The material distribution rod has teeth that create multiple grooves (air guide grooves or dividing lines) on the material surface. These grooves further reduce the local material thickness, forming channels for steam to pass through preferentially. This not only facilitates steam to penetrate from the bottom upwards, but also releases excess steam generated during the steaming process in a timely manner, preventing the material surface from bulging or cracking due to uneven pressure.

[0019] The integrated water and steam spray nozzles on the support bracket can provide localized and targeted spraying to the cracks formed when the support bracket lifts materials. Simultaneously, in cleaning mode, the nozzles can be adjusted via a drive mechanism to be closer to the conveyor belt, working in conjunction with the lifted conveyor belt to efficiently wash away impurities trapped within it, thus enhancing the equipment's self-cleaning capability.

[0020] Through the coordinated operation of the drive mechanism, inclined plate and push rod, the operator can easily adjust the depth of the material distribution teeth inserted into the material (i.e., the groove depth) according to the material characteristics (such as flowability and adhesion) and the process stage (such as the gelatinization zone).

[0021] The waste heat recovery device installed at the machine body opening uses heat exchange tubes to recover the heat of the discharged high-temperature steam to preheat the water supply, achieving energy recycling and reducing overall operating energy consumption. The combination of the suction hood and exhaust fan effectively controls steam leakage in the workshop and improves the working environment.

[0022] The material distribution device, through the coordination of the adjusting shaft, support plane, and spring, can precisely and stably adjust the distance between the material hopper and the conveyor belt, thereby controlling the material thickness. Simultaneously, the adjusting block automatically adjusts the discharge port opening according to changes in the height of the material hopper, automatically matching the material discharge amount with the required spreading thickness, ensuring the uniformity and stability of material distribution.

Detailed Implementation

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0025] like Figures 1 to 8 As shown, a curing conveyor belt includes a body 1, a mesh belt conveyor 2, and a support and material distribution device 3. The mesh belt conveyor 2 is installed inside the body 1. Openings 4 are provided on both sides of the body 1. The interior of the body 1 is a steam chamber. A steam pipe 9 is provided inside the body 1. The steam pipe 9 is connected to a steam source. A steam nozzle is provided on the steam pipe 9. Steam is sprayed out through the steam nozzle and enters the steam chamber.

[0026] A material spreading device 5 is provided at one opening 4 on one side of the machine body 1, and a discharge hopper 6 is provided at the other opening 4 on the machine body 1. The opening 4 corresponding to the material spreading device 5 is the feed inlet, and the opening 4 corresponding to the discharge hopper 6 is the discharge outlet. Rice or millet and other materials are spread onto the mesh belt conveyor 2 through the material spreading device 5, and the mesh belt conveyor 2 drives the material to move towards the discharge outlet; during the movement, the material is steamed and cooked.

[0027] The supporting material distribution device 3 includes a supporting bracket 30 and a material distribution rod 31. The supporting bracket 30 is slidably connected to the machine body 1. The machine body 1 is provided with a driving mechanism 32 connected to the supporting bracket 30. The supporting bracket 30 is driven to move by the driving mechanism 32, changing the contact position between the supporting bracket 30 and the upper mesh belt 20 of the mesh belt conveyor 2. The upper mesh belt 20 can also be lifted by the supporting bracket 30.

[0028] In existing steaming machines, the material is laid flat on the upper mesh belt 20, and it does not fluctuate during movement. Due to the thickness of the material, there is significant resistance to steam penetrating from the bottom of the material; similarly, there is also some resistance to water passing through the top of the material. Therefore, existing steaming machines sometimes result in undercooked food during the steaming process.

[0029] This steaming machine uses a support bracket 30 to make the material fluctuate during movement. Especially when passing the top of the support bracket 30, the upper gap of the material will increase or even form cracks, thereby reducing the difficulty of steam and water passing through and allowing the material passing through this area to come into more uniform contact with steam and water.

[0030] A support plate 315 is fixedly connected to the support bracket 30. The material distribution rod 31 is slidably connected to the support plate 315. The support plate 315 is provided with a corresponding first groove 34, and a first limiting protrusion 35 is provided in the first groove 34. A support spring 36 is provided between the material distribution rod 31 and the support plate 315. The material distribution rod 31 is provided with several material distribution teeth 37. The function of the material distribution teeth 37 is to form multiple grooves on the surface of the material. The thickness of the grooves is small, which can facilitate steam penetration, improve the contact between the material and the steam, and further prevent the occurrence of undercooked material.

[0031] The support plate 315 is equipped with a water cleaning nozzle 310, and the support bracket 30 is equipped with a steam nozzle 33; steam and water are sprayed locally and specifically at the crack.

[0032] A first inclined plate 38 is fixedly connected inside the machine body 1, and a first push rod 39 that cooperates with the first inclined plate 38 is provided on the material distribution rod 31. When the first push rod 39 contacts the first inclined plate 38 and moves along the first inclined plate 38, the distance between the material distribution rod 31 and the material distribution teeth 37 and the upper mesh belt 20 can be changed, thereby changing the depth of the formed groove.

[0033] The position of the dispensing rod 31 is changed by the drive mechanism 32, preferably located in the middle of the machine body 1, that is, in the middle section (gelatinization zone), the middle of the tunnel, the area with the most abundant steam supply; the material enters the key stage of starch gelatinization. Under the action of high temperature and high humidity, the starch granules absorb water, swell and rupture, and the rice grains change from translucent to opaque white, and the texture softens. At this time, the rice reaches a semi-cooked or fully cooked state.

[0034] Due to the position of the distributing rod 31 and the influence of the insertion depth of the distributing teeth 37, grooves are formed on the material surface, which can be classified as air guide grooves or dividing grooves. Simultaneously, if the position is too far forward, the rice grains, being fluid and sticky, may not form clear scratches, but instead push the grains to both sides, creating temporary depressions that may subsequently be partially filled by the flow of surrounding grains. Therefore, the position of the distributing rod 31 needs to be adjusted according to the actual discharge situation.

[0035] Air guide grooves: Linear grooves are drawn on the continuous rice layer. These grooves can release excess steam generated during the steaming process and prevent the surface of the rice layer from bulging or cracking due to uneven steam pressure.

[0036] Dividing line: If the goal is to divide a large layer of rice into several strips, the toothed tool can cut through the sticky rice layer, so that the rice grains remain in strip shape during subsequent transport.

[0037] Specifically, the left side of the first inclined plate 38 is the high point and the right side is the low point. When the support bracket 30 is driven to move to the right by the drive mechanism 32, the first push rod 39 cooperates with the first inclined plate 38, causing the first push rod 39 to push the material distribution rod 31 and the material distribution tooth 37 downward (the support spring 36 is compressed), thereby increasing the depth of the groove.

[0038] When the drive mechanism 32 drives the support bracket 30 to move to the left, the first push rod 39 will separate from the first inclined plate 38. After the first push rod 39 separates from the first inclined plate 38, the first limiting protrusion 35 limits the support plate 315 and the first push rod 39 to ensure that when it moves to the right again, the first push rod 39 can contact the first inclined plate 38, thus preventing the first push rod 39 from moving upward beyond the limit.

[0039] Furthermore, the support plate 315 is slidably connected to the water replenishment and cleaning nozzle 310, and a corresponding second sliding groove 311 is provided at the support plate 315. A first spring 312 is provided between the water replenishment and cleaning nozzle 310 and the support plate 315. A second inclined plate 313 is fixedly connected inside the machine body 1, and a second push rod 314 that cooperates with the second inclined plate 313 is provided on the material distribution rod 31 of the water replenishment and cleaning nozzle 310.

[0040] Similarly, a second limiting protrusion 316 can be provided in the second slide groove 311. When the drive mechanism 32 drives the support bracket 30 to move to the right, the second push rod 314 will separate from the second inclined plate 313. After the second push rod 314 separates from the second inclined plate 313, the second limiting protrusion 316 limits the water replenishment cleaning nozzle 310 and the second push rod 314 to ensure that when it moves to the left again, the second push rod 314 can contact the second inclined plate 313, thus preventing the second push rod 314 from moving upward beyond the limit.

[0041] The first inclined plate 38 and the second inclined plate 313 have opposite inclinations and are staggered; that is, the first push rod 39 only cooperates with the first inclined plate 38, and the second push rod 314 only cooperates with the second inclined plate 313. That is, the left side of the second inclined plate 313 is the lower point, and the right side is the higher point; when the support bracket 30 is driven to move to the left by the drive mechanism 32, the second push rod 314 cooperates with the second inclined plate 313, causing the water replenishment cleaning nozzle 310 to move down, shortening the distance between it and the upper mesh belt 20.

[0042] When the support bracket 30 is driven to move to the right by the drive mechanism 32, the first push rod 39 and the first inclined plate 38 are engaged; the second push rod 314 and the second inclined plate 313 are disengaged and limited by the second limiting protrusion 316. Conversely, when the support bracket 30 is driven to move to the left by the drive mechanism 32, the first push rod 39 and the first inclined plate 38 are disengaged and limited by the first limiting protrusion 35; at this time, the second push rod 314 and the second inclined plate 313 are engaged.

[0043] The water replenishment and cleaning nozzle 310 is connected to a water source and has a nozzle on it through which water is sprayed out. Therefore, during the steaming and cooking process, when the first push rod 39 and the first inclined plate 38 are in a coordinated state, the height of the water replenishment and cleaning nozzle 310 will not change; only the height of the material distribution teeth 37 will change. At this time, the water replenishment and cleaning nozzle 310 mainly plays the role of localized targeted water replenishment.

[0044] When the material distribution tooth 37 needs cleaning, there is no material on the conveyor belt, and the material distribution tooth 37 is exposed; this puts the first push rod 39 and the first inclined plate 38 into a mating state; at this time, the position of the water replenishment cleaning nozzle 310 is higher than the material distribution tooth 37, and the back (right side) of the material distribution tooth 37 can be cleaned by the water sprayed from the water replenishment cleaning nozzle 310. Specifically, a cleaning nozzle 12 is provided on the material distribution rod 31, and the cleaning nozzle 12 is aimed at the front (left side) of the material distribution tooth 37, and the front of the material distribution tooth 37 is cleaned by spraying water.

[0045] After steaming and cooking, when the conveyor belt needs to be cleaned (the water cleaning nozzle 310 plays a cleaning role), when the second top rod 314 and the second inclined plate 313 are in a coordinated state, the height of the water cleaning nozzle 310 is lowered, shortening the distance between it and the upper conveyor belt 20. At the same time, the support bracket 30 will lift the conveyor belt, allowing the water sprayed from the water cleaning nozzle 8 to flush out impurities mixed in with the conveyor belt, further improving the cleaning effect.

[0046] Furthermore, the machine body 1 is equipped with a water replenishment spray pipe assembly 7, which consists of several water spray pipes, each with a nozzle and connected to a water source, allowing water to be sprayed out. The water replenishment spray pipe assembly 7 is located above the upper mesh belt 20, and sprays water to replenish the material on the upper mesh belt 20.

[0047] A cleaning pipe 8 is installed inside the machine body 1. The cleaning pipe 8 is located above the lower mesh belt 21 of the mesh belt conveyor 2. The cleaning pipe 8 is also connected to a water source and is only opened during cleaning. It can be controlled by setting an appropriate valve. By cooperating with the water replenishment cleaning pipe 8, the mesh belt can be thoroughly cleaned.

[0048] Furthermore, the lower end of the separating tooth 37 is a pointed portion 370, and the front of the separating tooth 37 is provided with a separating inclined surface 371; the separating teeth 37 are spaced apart. The above structural arrangement makes it easier to insert into the material and form a groove.

[0049] Furthermore, the support bracket 30 includes a support rod 300 and a semi-circular top plate 301. At least two semi-circular top plates 301 are provided, and the semi-circular top plates 301 are fixedly connected to each other by the support rod 300. The outer surface of the semi-circular top plate 301 contacts the lower surface of the upper mesh belt 20, thus lifting it up.

[0050] Furthermore, the drive mechanism 32 includes a drive screw 320 and a drive motor 321. The drive screw 320 is rotatably connected to the machine body 1, and the support bracket 30 is threadedly connected to the drive screw 320. The housing of the drive motor 321 is fixedly connected to the machine body 1. Transmission wheels 322 are fixedly connected to both the output shaft of the drive motor 321 and the drive screw 320. The two transmission wheels 322 are connected by a belt or chain for transmission. The left and right movement of the support bracket 30 is achieved by rotating the output shaft of the drive motor 321 in both directions.

[0051] Furthermore, each of the openings 4 on both sides of the machine body 1 has a waste heat recovery device. The waste heat recovery device includes a recovery hood 10, a suction hood 11, and heat exchange tubes. The recovery hood 10 is connected to the steam chamber and fixedly connected to the machine body 1. The suction hood 11 is located above the recovery hood 10. The heat exchange tubes are installed inside the recovery hood 10, and the recovery hood 10 has several through holes (not shown in the figure). The heat exchange tubes can be spiral tubes, with one end as the inlet and the other end as the outlet. Water enters from the inlet and exits from the outlet. The water in the heat exchange tubes absorbs the heat from the steam entering the recovery hood 10 and is heated. The heated water can be used as makeup water or for other processes.

[0052] The suction hood 11 is connected to an exhaust fan via a pipe, which is mainly used to extract the steam that passes through the suction hood 11 and the four openings at both ends.

[0053] Furthermore, the machine body 1 is equipped with an openable and closable steam hood 13, which allows for internal maintenance and other repairs. A drain hopper 14 is located at the bottom of the machine body 1, and a drain pipe is installed on the drain hopper 14, through which condensate or cleaning water can be discharged.

[0054] Furthermore, the material spreading device 5 includes a material hopper 50 and an adjusting component 51. The distance between the bottom of the material hopper 50 and the upper mesh belt 20 is adjusted by the adjusting component 51, thereby changing the thickness of the material spread. The two sides of the material hopper 50 are connected to the machine body 1 by connecting components 52 respectively; the material hopper 50 is located above the upper mesh belt 20.

[0055] The connecting assembly 52 includes a connecting post 520 and a connecting plate 521. The connecting plate 521 is fixedly connected to the fabric hopper 50. The lower end of the connecting post 520 is fixedly connected to the machine body 1. The connecting plate 521 and the connecting post 520 are slidably connected. The connecting post 520 is provided with a second spring 522 that cooperates with the connecting plate 521. The second spring 522 is sleeved on the outside of the connecting post 520, and the two ends of the second spring 522 are fixedly connected to the connecting post 520 and the connecting plate 521, respectively.

[0056] The adjustment assembly 51 includes an adjustment shaft 510 and an adjustment wheel 511. The adjustment wheel 511 is fixedly connected to the adjustment shaft 510. Both ends of the adjustment shaft 510 pass through the cloth hopper 50 and are rotatably connected to the machine body 1. The cloth hopper 50 is provided with corresponding waist-shaped through holes 512, and a sealing structure can be set at the waist-shaped through holes 512.

[0057] By rotating the adjusting shaft 510, any supporting surface 513 can be brought into contact with the connecting plate 521. The supporting surface 513 contacts the lower surface of the connecting plate 521 and supports the connecting plate 521. Specifically, the adjusting wheel 511 is provided with at least two supporting surfaces 513, and the vertical distance (D) between each supporting surface 513 and the center of the adjusting shaft 510 is different. That is, after different supporting surfaces 513 come into contact with the connecting plate 521, the height of the connecting plate 521 and the cloth hopper 50 can be changed, thus achieving the adjustment function. For convenient adjustment, an adjusting handle can be fixed to the end of the adjusting shaft 510. Under the action of the second spring 522, the connecting plate 521 can be made to fit against the supporting surface 513.

[0058] Furthermore, a pair of feed ramps 514 are fixedly connected inside the feed hopper 50, with a gap between the bottoms of the pair of feed ramps 514 forming a feed opening; an adjusting block 515 is slidably connected inside the feed hopper 50, and the adjusting block 515 is located below the feed opening; the adjusting block 515 is rotatably connected to the adjusting shaft 510. When the adjusting block 515 is provided, the sealing structure at the waist-shaped through hole 512 can be omitted, that is, the side of the adjusting block 515 can block the waist-shaped through hole 512, preventing material from leaking out from the waist-shaped through hole 512.

[0059] The height of the adjusting block 515 remains constant. When the height of the feeding hopper 50 changes, the distance between the adjusting block 515 and the discharge port also changes.

[0060] When the spreading thickness needs to be increased, the spreading hopper 50 moves upward, and the distance between the adjusting block 515 and the discharge port also increases, thereby increasing the discharge volume and speed at the discharge port. Conversely, when the spreading thickness needs to be decreased, the spreading hopper 50 moves downward, and the distance between the adjusting block 515 and the discharge port also decreases, hindering the downward movement of the material and thus reducing the discharge volume and speed at the discharge port.

[0061] The above description only illustrates preferred embodiments of the present invention, but the present invention is not limited to the above embodiments.
