Description

Technical Field

[0001] This invention relates to the field of chili powder seasoning sterilization technology, specifically to a batch sterilization device and sterilization method for chili powder seasoning. Background Technology

[0002] Chili powder, a commonly used condiment, requires sterilization during its production to kill residual microorganisms, extend shelf life, and ensure food safety. Existing chili powder sterilization methods mainly include high-temperature hot air sterilization, microwave sterilization, and steam sterilization. Among these, steam sterilization is widely used due to its strong penetration and good sterilization effect. Currently, steam sterilization devices for powdered materials typically use trays to hold the material, which are then placed into a sealed chamber where high-temperature steam is introduced for sterilization.

[0003] However, existing sterilization devices have the following drawbacks: First, chili powder tends to clump during sterilization, making it difficult for steam to penetrate the material evenly, resulting in incomplete sterilization. This is especially true for chili powder packaged in breathable cloth bags, where the bags are tightly fitted to the bottom of the tray, preventing steam from effectively reaching the bottom and creating numerous sterilization dead zones. Second, existing sterilization devices mostly spray steam in a single direction or from a single location, failing to simultaneously clean the bottom and sides of the material, resulting in poor sterilization uniformity and efficiency. Third, the transmission structure is complex, often relying on motors to drive multiple actuators, leading to high device costs, high energy consumption, and poor reliability in humid and hot environments. Summary of the Invention

[0004] The purpose of this invention is to provide a batch sterilization device and method for chili powder seasonings to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows: A batch sterilization device for chili powder seasoning includes a control box, a transmission structure, a synchronous pulley set, a state adjustment component, a tray, a vibrating plate assembly, and an air supply plate assembly. The control box has an outer insulation box on one side. A U-shaped internal heating component is installed on the inner wall of the outer insulation box. A transmission structure is installed at the bottom of the U-shaped internal heating component. The transmission structure is sequentially connected to multiple synchronous pulley sets from top to bottom. Each synchronous pulley set is connected to a symmetrically arranged state adjustment component. The end of each state adjustment component is intermittently engaged with the tray and the air supply plate assembly. The state adjustment component includes two horizontally arranged rotating rods, one end of which is connected to a set of synchronous pulleys. The outer rings of the two rotating rods are respectively connected to the inner rings of the upper and lower cams. The upper cam is intermittently driven by the edge of the tray, and the lower cam is intermittently driven by the air supply plate assembly.

[0006] Furthermore, one end of the rotating rod is connected to the synchronous belt pulley assembly for transmission, and the outer ring of the other end of the rotating rod is connected to an automatic reset assembly, which is connected to the internal heating assembly.

[0007] Furthermore, the automatic reset assembly includes symmetrically arranged engaging blocks, one of which has its inner ring connected to a rotating rod, and the other has its inner ring anti-rotation slidingly engaged with a fixed rod. The fixed rod and the rotating rod are horizontally coaxially arranged, and a support frame is connected to one end of the fixed rod away from the rotating rod. A first elastic element is provided between the support frame and the other engaging block, and the first elastic element is sleeved on the outer ring of the fixed rod.

[0008] Furthermore, the air supply plate assembly includes a lower top plate, which is located above the lower cam. The lower edge of the lower top plate is intermittently driven by the lower cam. Multiple exhaust air knife assemblies are equidistantly installed on the top of the lower top plate. Hollowed-out clearance grooves are equidistantly opened on the surface of the lower top plate. Vibration plate assemblies are provided between the clearance grooves. The lower top plate is slidably engaged with the support frame.

[0009] Furthermore, the vibrating tray assembly includes a support plate located below the clearance groove. Multiple telescopic elastic elements are symmetrically and equidistantly installed on the upper surface of the support plate. The top of each telescopic elastic element slides in engagement with the bottom of the tray. The support plate is symmetrically provided with guide plates. The guide plates have inclined surfaces on their opposite sides. The vertical surface of the support plate slides in engagement with the vertical surface of the tray. Both ends of the guide plates are connected to the inner wall of the inner heating component. Multiple hollowed-out top slots are equidistantly opened on the bottom surface of the tray.

[0010] Furthermore, the transmission structure includes a first steam pipe, a pneumatic rotary motor, a second steam pipe, and a third steam pipe. The upper end of the first steam pipe is connected to the internal heating component and the external insulation box. The ventilation path of the first steam pipe is connected to multiple vertically arranged pneumatic rotary motors. The pneumatic rotary motors are connected to a rotating rod. The lower end of the first steam pipe is connected to the second steam pipe. The second steam pipe is connected to one end of multiple third steam pipes. The third steam pipes are connected to multiple exhaust air knife assemblies.

[0011] Furthermore, the exhaust air knife assembly includes a hollow rectangular block. The bottom of the hollow rectangular block is fixedly connected to the surface of the lower top plate. The hollow rectangular block slides with a clearance fit to the top slot hole opened in the tray. The top of the hollow rectangular block is an arc surface. Exhaust slots are opened at the lower end of the arc surface and on both sides of the hollow rectangular block. A frame-shaped cover is provided on the inner wall of the hollow rectangular block. An arc-shaped cover is provided on the inner wall of the arc surface of the hollow rectangular block. The inner ring of the frame-shaped cover is connected to both sides of the T-shaped block. The lower end of the arc-shaped cover is connected to the top of the T-shaped block. The bottom of the T-shaped block is connected to the upper end of the reset elastic element. The lower end of the reset elastic element is connected to the lower inner wall of the hollow rectangular block.

[0012] Furthermore, the internal heating component includes a U-shaped sleeve connected to an outer insulation box, forming a U-shaped cavity between the U-shaped sleeve and the outer insulation box. A first U-shaped partition and a second U-shaped partition are alternately arranged on one side of the outer wall of the U-shaped sleeve. A heating pipe is disposed between the first and second U-shaped partitions and installed on the outer wall of the U-shaped sleeve. A vertical partition plate is installed at the bottom of the groove of the U-shaped sleeve. A vent hole is opened at the upper end of the U-shaped sleeve, and the vent hole is connected to a first steam pipe. A pneumatic rotary motor and a synchronous pulley assembly are installed between the partition plate and the U-shaped sleeve. A first rectangular through hole is opened at both ends of the first U-shaped partition, and a second rectangular through hole is opened at the bottom of the groove of the second U-shaped partition.

[0013] A batch sterilization method for chili powder seasoning, using the aforementioned batch sterilization device for chili powder seasoning, includes the following steps: S1: Fill the chili powder into a breathable cloth bag and lay the bag flat on the tray so that the bottom of the bag completely covers all the top slot holes; transport the tray containing the cloth bag to the designated location by a trolley, and then push the tray into the outer insulation box, so that the bottom of the tray slides and locks onto multiple telescopic elastic elements of the vibrating plate assembly, and falls between two symmetrically arranged support plates. The vertical surface of the tray slides and engages with the vertical surface of the support plate, restricting the tray to vibrate only vertically. At the same time, the top slot holes are aligned vertically with the exhaust air knife assembly of the air supply plate assembly; control the heating tube of the inner heating component to be turned on through the control box. The heating tube is preheated first, and then the steam is used to insulate the interior of the outer insulation box through the heating channel formed by the U-shaped sleeve, the first U-shaped partition and the second U-shaped partition. The control box monitors and adjusts the heating power in real time to maintain a constant temperature. S2: The control box controls the steam to enter the first steam pipe of the transmission mechanism. The steam first enters the air inlet of the pneumatic rotary motor, drives it to rotate, and then drives the rotating rod, the synchronous belt pulley group and the state adjustment component to operate. The rotating rod in the state adjustment component is arranged horizontally up and down. The synchronous belt pulley group drives multiple rotating rods to rotate synchronously in the same direction. The rotating rod drives the convex parts of the upper cam and the lower cam to be arranged in opposite phases in the circumferential direction, so that when the convex part of the upper cam pushes, the lower cam is in the base circle release state. The steam discharged from the exhaust end of the pneumatic rotary motor then enters the second steam pipe and the third steam pipe in sequence, and is delivered to the hollow rectangular block of the exhaust air knife assembly. The rotating rod rotates continuously, causing the upper and lower cams to rotate synchronously in the same direction. When the protruding part of the lower cam rotates to push the lower top plate of the air supply plate assembly, the lower top plate slides upward along the support frame, causing the hollow rectangular block of the exhaust air knife assembly to insert into the top slot hole of the tray. At this time, the protruding part of the upper cam rotates downward and is in a released state. Under its own weight and the elastic action of the telescopic elastic element, the tray falls downward instantly to create a clearance gap, allowing steam to enter the bottom of the breathable cloth bag. The arc surface at the top of the hollow rectangular block pushes up a local area at the bottom of the cloth bag to form an arc-shaped gap. Steam is ejected from the top surface and both sides of the exhaust groove at the same time, penetrating the cloth bag in all directions and entering the chili powder layer. After the rotating rod continues to rotate half a turn, the protruding part of the upper cam moves upward to push the corner of the tray, lifting the tray upward and causing the bottom of the bag to separate from the hollow rectangular block; at this time, the protruding part of the lower cam moves downward and is in the released state, the lower top plate descends and causes the hollow rectangular block to exit the top slot hole, and the bag naturally falls back to the bottom of the tray; the telescopic elastic element continues to generate residual elastic vibration during the tray's descent and vibration, shaking the chili powder. Each time the rotating rod rotates one turn, the upper cam and the lower cam each complete one push and one release, repeating the above cycle until the set sterilization time ends; After the set sterilization time is reached, the steam boiler is depressurized, the pneumatic rotary motor stops rotating, and the rotating rod stops rotating. At this time, the two engaging blocks that rotate with the rotating rod stop at a certain position, while the other engaging block (741) that is in anti-rotation sliding cooperation with the fixed rod is pushed by the first elastic element, causing the rotating engaging block to rotate in the opposite direction, driving the rotating rod and the upper and lower cams back to the initial phase, so that the hollow rectangular block (1021) exits the top slot hole (81), and the tray can be pulled out. S3: During the sterilization process, hot and humid gas is discharged through the exhaust vent, check valve and exhaust fan at the top of the outer insulation box. The control box adjusts the exhaust fan to maintain the humidity and pressure inside the box. After the set sterilization time is reached, the first steam pipeline is closed, the pneumatic rotary motor stops rotating, and all components automatically reset. After the temperature inside the box drops to a safe range, the outer insulation box is opened, the tray is pulled out using a trolley, and the sterilized cloth bag is taken out for subsequent drying and packaging processes.

[0014] Compared with the prior art, the present invention has the following beneficial effects: (1) Through the alternating push design of the upper and lower cams in opposite phases, the cloth bag achieves dynamic shape transformation during sterilization: when the lower cam pushes the air knife into the tray, the upper cam releases simultaneously, and the tray falls instantly downward under its own weight and the action of the telescopic elastic element, producing a dual effect: on the one hand, a clearance gap is formed between the tray and the air knife, providing a channel for steam to enter the bottom of the cloth bag; on the other hand, the impact force generated by the fall is directly transmitted to the cloth bag, causing the cloth bag and the chili powder inside to vibrate instantaneously, achieving the initial loosening of the powder. The arc surface of the air knife partially lifts the cloth bag to form an arc-shaped gap, and steam is sprayed in from three sides of the exhaust groove at the same time; after the cloth bag falls back to the tray, the residual elastic vibration of the telescopic elastic element continues to shake off the powder adhering to the inner wall of the cloth bag, preventing clumping. This solves the defects of the cloth bag and the tray being tightly fitted, which prevents steam from entering the bottom and the steam penetration efficiency being poor; (2) By replacing the traditional motor drive with a steam-driven pneumatic rotary motor, high-temperature steam is used to simultaneously achieve power output and sterilization, eliminating the need for external power supply and avoiding the risk of electrical component failure in humid and hot environments. At the same time, the outer wall of the U-shaped sleeve of the internal heating component is alternately equipped with a first U-shaped partition and a second U-shaped partition. The first U-shaped partition has a first rectangular perforation at both ends, and the second U-shaped partition has a second rectangular perforation at the bottom of the groove, so that the steam forms a back-and-forth flow path in the U-shaped sleeve, which prolongs the heat exchange time between the steam and the heating tube, realizes uniform temperature distribution and efficient heat preservation in the box, and further reduces energy consumption. The steam first enters the pneumatic rotary motor to drive the rotating rod, upper cam and lower cam to operate. The steam discharged from the pneumatic rotary motor is sent to the exhaust air knife assembly for sterilization through the second steam pipeline and the third steam pipeline in sequence, realizing the cascade utilization of energy. The device has high overall energy efficiency and good reliability. (3) The automatic reset assembly achieves precise maintenance of the opposite phase between the upper and lower cams. The automatic reset assembly includes opposing engagement blocks, a fixed rod, a support frame, and a first elastic element sleeved on the outer ring of the fixed rod. One engagement block is connected to the rotating rod for transmission, and the other engagement block is anti-rotationally slidably engaged with the fixed rod. After the cam completes its pushing action, the first elastic element pushes the engagement block to drive the rotating rod to reset, ensuring that the upper and lower cams always maintain an opposite phase relationship, and the cyclic action is stable and reliable. At the same time, the automatic reset assembly is arranged to the side or below the support frame and the internal heating assembly. When the exhaust air knife assembly is not in operation, it is completely withdrawn from the top slot and lower than the bottom surface of the tray. Both completely avoid the tray's entry and exit path. When the trolley is pulled out of the tray after sterilization, there will be no interference or obstruction, ensuring the convenience and smoothness of batch operation. Attached Figure Description

[0018] like Figures 1 to 10 As shown, a batch sterilization device for chili powder seasoning includes a control box 1, a transmission structure 5, a synchronous pulley set 6, a state adjustment component 7, a tray 8, a vibrating plate assembly 9, and an air supply plate assembly 10. An external insulation box 2 is provided on one side of the control box 1 to provide a sealed sterilization environment and maintain a stable internal temperature. A U-shaped internal heating component 4 is installed on the inner wall of the external insulation box 2. This internal heating component 4 is used to preheat and maintain the temperature inside the box, ensuring uniform sterilization temperature. A transmission structure 5 is installed at the bottom of the U-shaped internal heating component 4. Multiple synchronous pulley sets 6 are sequentially connected from top to bottom in the transmission structure 5 to achieve graded power transmission. Each synchronous pulley set 6 is connected to a symmetrically arranged state adjustment component 7. The end of each state adjustment component 7 is intermittently engaged with the tray 8 and the air supply plate assembly 10, thereby driving the tray 8 and the air supply plate assembly 10 to alternately move, achieving periodic lifting and lowering and repositioning.

[0019] The state adjustment component 7 includes two horizontally arranged rotating rods 71. One end of each rotating rod 71 is connected to a set of synchronous pulleys 6 to obtain synchronous rotational power. The outer rings of the ends of the two rotating rods 71 ​​are respectively connected to the inner rings of the upper cam 72 and the lower cam 73. The upper cam 72 intermittently drives the corner of the tray 8 to periodically rise; the lower cam 73 intermittently drives the air supply plate assembly 10 to periodically rise. By having the protruding parts of the upper cam 72 and the lower cam 73 arranged in opposite phases, they alternately push, realizing the alternating raising and lowering of the tray 8 and the air supply plate assembly 10, providing a dynamic gap for steam penetration sterilization.

[0020] One end of the rotating rod 71 is connected to the synchronous belt pulley group 6 for transmission, and the other end of the rotating rod 71 is connected to the outer ring of the automatic reset component 74 for transmission. The automatic reset component 74 is connected to the internal heating component 4 and is used to drive the rotating rod 71 back to the initial phase when the machine stops, so as to ensure that the exhaust air knife component 102 is completely removed from the top slot hole 81 of the tray 8, which facilitates the pushing in and pulling out of the tray 8.

[0021] Specifically, the automatic reset assembly 74 includes symmetrically arranged engaging blocks 741. The inner ring of one engaging block 741 is connected to the rotating rod 71 and rotates synchronously with the rotating rod 71. The inner ring of the other engaging block 741 is anti-rotationally slidingly engaged with the fixed rod 743, allowing it to slide only along the axial direction of the fixed rod 743 and preventing rotation. The fixed rod 743 and the rotating rod 71 are horizontally coaxial. A support frame 744 is connected to one end of the fixed rod 743 away from the rotating rod 71. A first elastic element 742 is provided between the support frame 744 and the other engaging block 741, and the first elastic element 742 is sleeved on the outer ring of the fixed rod 743. When the machine stops, the first elastic element 742 pushes the engaging block 741 that is slidingly engaged with the fixed rod 743, causing the engaging block 741, which is connected to the rotating rod 71, to drive the rotating rod 71 to rotate in the opposite direction and reset.

[0022] The air supply baffle assembly 10 includes a lower top plate 101, which is located above the lower cam 73. The lower edge of the lower top plate 101 is intermittently driven by the lower cam 73. When the protruding part of the lower cam 73 rotates to the top, it pushes the lower top plate 101 upward. Multiple exhaust air knife assemblies 102 are equidistantly installed on the top of the lower top plate 101 for injecting steam into the filter bag. The surface of the lower top plate 101 has equidistantly perforated clearance grooves 103 to provide installation space for the vibrating baffle assembly 9 and avoid motion interference. The vibrating baffle assembly 9 is installed between the clearance grooves 103. The lower top plate 101 slides in conjunction with the support frame 744 to ensure that the lower top plate 101 can only rise and fall smoothly in the vertical direction.

[0023] The vibrating tray assembly 9 includes a support plate 91 located below the relief groove 103. Multiple telescopic elastic elements 92 are symmetrically and equidistantly installed on the upper surface of the support plate 91. The tops of the telescopic elastic elements 92 slide against the bottom of the tray 8, providing elastic support to the tray 8 and generating residual vibration to disperse clumps of chili powder. The support plate 91 is symmetrically provided with guide plates 93, each with a sloping back surface for guiding and positioning the tray 8 when pushed in. The vertical surface of the support plate 91 slides against the vertical surface of the tray 8, restricting the tray 8 to vibrate only vertically. The guide plates 93 are connected at both ends to the inner wall of the inner heating assembly 4. Multiple perforated top slots 81 are equidistantly opened on the bottom surface of the tray 8, allowing the air supply and exhaust knife assembly 102 to penetrate steam into the bottom of the cloth bag.

[0024] The transmission structure 5 includes a first steam pipe 51, a pneumatic rotary motor 52, a second steam pipe 53, and a third steam pipe 54. The upper end of the first steam pipe 51 connects to the internal heating assembly 4 and the external insulation box 2, for introducing high-temperature steam. The ventilation path of the first steam pipe 51 connects to multiple vertically arranged pneumatic rotary motors 52. The pneumatic rotary motors 52 are connected to a rotating rod 71 and are driven by steam pressure to achieve power output. Steam discharged from the exhaust end of the pneumatic rotary motor 52 sequentially enters the second steam pipe 53 and the third steam pipe 54, and is finally delivered to the exhaust air knife assembly 102 for sterilization, realizing the cascade utilization of steam power. The lower end of the first steam pipe 51 connects to the second steam pipe 53, the second steam pipe 53 connects to one end of multiple third steam pipes 54, and the third steam pipes 54 connect to multiple exhaust air knife assemblies 102.

[0025] The exhaust air knife assembly 102 includes a hollow rectangular block 1021. The bottom of the hollow rectangular block 1021 is fixedly connected to the surface of the lower top plate 101 and rises and falls synchronously with the lower top plate 101. The hollow rectangular block 1021 slides smoothly into and out of the top slot hole 81 of the tray 8. The top of the hollow rectangular block 1021 is an arc surface, which is used to partially lift the bottom of the cloth bag to form an arc-shaped gap during insertion, increasing the contact area between the steam and the chili powder. Exhaust grooves 1022 are provided at the lower end of the arc surface and on both sides of the hollow rectangular block 1021, so that steam is sprayed out from the top surface and the sides simultaneously, achieving all-round penetration sterilization. The hollow rectangular block 1021 has a frame-shaped cover 1023 on its inner wall and an arc-shaped cover 1024 on its inner wall of the arc surface. The inner ring of the frame-shaped cover 1023 is connected to both sides of the T-shaped block 1025, and the lower end of the arc-shaped cover 1024 is connected to the top of the T-shaped block 1025. The bottom of the T-shaped block 1025 is connected to the upper end of the reset elastic element 1026, and the lower end of the reset elastic element 1026 is connected to the lower inner wall of the hollow rectangular block 1021. When steam is introduced, the steam pressure pushes the T-shaped block 1025 to compress the reset elastic element 1026, opening the frame-shaped cover 1023 and the arc-shaped cover 1024 to form a jet channel. After the steam is turned off, the reset elastic element 1026 pushes the T-shaped block 1025 to reset and close the channel, preventing dust backflow.

[0026] The internal heating component 4 includes a U-shaped sleeve 41, which is connected to the outer insulation box 2. A U-shaped cavity is formed between the U-shaped sleeve 41 and the outer insulation box 2 to accommodate the heating element and form a hot air circulation channel. A first U-shaped partition 42 and a second U-shaped partition 43 are alternately arranged on one side of the outer wall of the U-shaped sleeve 41. A heating pipe 44 is arranged between the first U-shaped partition 42 and the second U-shaped partition 43, and is installed on the outer wall of the U-shaped sleeve 41 to heat the circulating steam. First rectangular perforations are opened at both ends of the first U-shaped partition 42, and second rectangular perforations are opened at the bottom of the second U-shaped partition 43, allowing the steam to form a back-and-forth flow path within the U-shaped sleeve 41, extending the heat exchange time and improving heating efficiency and temperature uniformity. A vertical partition plate 45 is installed at the bottom of the U-shaped sleeve 41 to separate and fix the internal components. A vent is opened at the upper end of the U-shaped sleeve 41, which is connected to the first steam pipe 51 to introduce the heated steam into the transmission structure 5. A pneumatic rotary motor 52 and a synchronous pulley set 6 are installed between the partition plate 45 and the U-shaped sleeve 41.

[0027] An exhaust vent is provided on the top of the external insulation box 2. A check valve is installed at the lower end of the exhaust vent to prevent backflow of external air. An exhaust fan 3 is installed at the upper end of the exhaust vent to discharge hot and humid gas during the sterilization process. The exhaust fan 3 is adjusted by the control box 1 to maintain the humidity and pressure balance inside the control box 1.

[0028] The working principle and usage process of this invention are as follows: Chili powder is placed into a breathable cloth bag made of high-temperature resistant, food-grade filter cloth. The size of the bag matches the bottom area of ​​the tray 8. The bag is laid flat on the tray 8 so that the bottom of the bag completely covers all the top slot holes 81. The tray 8 containing the bag is transported to its position by a trolley, and then the tray 8 is pushed into the outer insulation box 2, so that the bottom of the tray 8 slides and locks onto the multiple telescopic elastic elements 92 of the vibrating plate assembly 9, and falls between the two symmetrically arranged support plates 91. The vertical surface of the tray 8 slides in conjunction with the vertical surface of the support plate 91, restricting the tray 8 to vibrate only vertically. At the same time, the top slot hole 81 is aligned vertically with the exhaust air knife assembly 102 of the air supply plate assembly 10. The heating tube 44 of the internal heating assembly 4 is opened by the control box 1. The heating tube 44 is preheated first, and then the steam is used to keep the interior of the external insulation box 2 warm through the heating channel formed by the U-shaped sleeve 41, the first U-shaped partition 42 and the second U-shaped partition 43. The control box 1 monitors and adjusts the heating power in real time to maintain a constant temperature.

[0029] The control box 1 controls the steam to enter the first steam pipe 51 of the transmission structure 5. The steam first enters the air inlet of the pneumatic rotary motor 52, driving it to rotate, which in turn drives the rotating rod 71, the synchronous pulley group 6 and the state adjustment component 7 to operate. The rotating rod 71 in the state adjustment component 7 is arranged horizontally up and down. The synchronous pulley group 6 drives multiple rotating rods 71 ​​to rotate synchronously in the same direction. The rotating rod 71 drives the convex parts of the upper cam 72 and the lower cam 73 to be arranged in opposite phases in the circumferential direction, so that when the convex part of the upper cam 72 pushes, the lower cam 73 is in the base circle release state. The steam discharged from the exhaust end of the pneumatic rotary motor 52 then enters the second steam pipe 53 and the third steam pipe 54 in sequence, and is delivered to the hollow rectangular block 1021 of the exhaust air knife assembly 102.

[0030] Rotating rod 71 rotates continuously, causing upper cam 72 and lower cam 73 to rotate synchronously in the same direction. When the protruding part of lower cam 73 rotates to push the lower top plate 101 of air supply plate assembly 10, the lower top plate 101 slides upward along support frame 744, causing the hollow rectangular block 1021 of exhaust air knife assembly 102 to insert into the top groove hole 81 of tray 8; at this time, the protruding part of upper cam 72 rotates downward and is in a released state. Under its own weight and the elastic action of telescopic elastic element 92, tray 8 falls downward instantly to create a clearance gap, allowing steam to enter the bottom of breathable cloth bag. The arc surface at the top of hollow rectangular block 1021 lifts a local area at the bottom of the cloth bag to form an arc-shaped gap. Steam is ejected from the top surface and both sides of exhaust groove 1022 at the same time, penetrating the cloth bag in all directions and entering the chili powder layer.

[0031] After the rotating rod 71 continues to rotate half a turn, the protruding part of the upper cam 72 moves to the upper corner of the tray 8, pushing the tray 8 upward and causing the bottom of the bag to detach from the hollow rectangular block 1021. At this time, the protruding part of the lower cam 73 moves downward and is in the released state. The lower top plate 101 descends, causing the hollow rectangular block 1021 to exit the top slot hole 81, and the bag naturally falls back to the bottom of the tray 8. The telescopic elastic element 92 continuously generates residual elastic vibration during the falling and vibration of the tray 8, shaking the chili powder. For each rotation of the rotating rod 71, the upper cam 72 and the lower cam 73 each complete one push and one release, repeating the above cycle of "lifting → giving way → three-sided exhaust → switching → bag falling → vibration and powder shaking" until the set sterilization time ends.

[0032] After the set sterilization time is reached, the steam boiler depressurizes, the pneumatic rotary motor 52 stops rotating, and the rotating rod 71 stops rotating. At this time, the engaging block 741 that rotates with the rotating rod 71 stops at a certain position, while the other engaging block 741, which is anti-rotationally slidingly engaged with the fixed rod 743, is pushed by the first elastic element 742, causing the rotating engaging block 741 to rotate in the opposite direction, driving the rotating rod 71 and the upper cam 72 and lower cam 73 back to the initial phase, so that the hollow rectangular block 1021 exits the top slot hole 81, and the tray 8 can be pulled out.

[0033] During the sterilization process, hot and humid gas is discharged through the exhaust vent, check valve, and exhaust fan 3 at the top of the outer insulation box 2. The control box 1 adjusts the exhaust fan 3 to maintain the humidity and pressure inside the box. After the set sterilization time is reached, the first steam pipe 51 is closed, the pneumatic rotary motor 52 stops rotating, and all components automatically reset. After the temperature inside the box drops to a safe range, the outer insulation box 2 is opened, the tray 8 is pulled out using a trolley, and the sterilized cloth bag is taken out for subsequent drying and packaging processes.

[0034] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the present invention. The scope of protection of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within its spirit and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of the present invention.

A batch sterilization method for chili powder seasoning, using the batch sterilization apparatus for chili powder seasoning as described in any one of claims 1-9, comprising the following steps: S1: Put chili powder into a breathable cloth bag, lay the bag flat on the tray (8) so that the bottom of the bag completely covers all the top slot holes (81); transport the tray (8) containing the cloth bag to the designated location by a trolley, and then push the tray (8) into the outer insulation box (2), so that the bottom of the tray (8) slides and locks onto the multiple telescopic elastic elements (92) of the vibrating plate assembly (9), and falls between the two symmetrically arranged support plates (91). The vertical surface of the tray (8) slides and engages with the vertical surface of the support plate (91), restricting the tray ( 8) It can only vibrate up and down in the vertical direction, and the top slot hole (81) is aligned with the exhaust air knife assembly (102) of the air supply plate assembly (10); the heating tube (44) of the inner heating assembly (4) is opened by the control box (1). The heating tube (44) is preheated first, and then the steam is insulated inside the outer heat insulation box (2) through the heating channel formed by the U-shaped sleeve (41), the first U-shaped partition (42) and the second U-shaped partition (43). The control box (1) monitors and adjusts the heating power in real time to maintain a constant temperature. S2: The control box (1) controls the steam to enter the first steam pipe (51) of the transmission mechanism (5). The steam first enters the air inlet of the pneumatic rotary motor (52) and drives it to rotate, which in turn drives the rotating rod (71), the synchronous belt pulley group (6) and the state adjustment component (7) to operate. The rotating rod (71) in the state adjustment component (7) is arranged horizontally up and down. The synchronous belt pulley group (6) drives multiple rotating rods (71) to rotate synchronously in the same direction. The rotating rod (71) drives the upper cam (72) and the lower cam (73) to be arranged in opposite phases in the circumferential direction. When the upper cam (72) is pushed, the lower cam (73) is in the base circle release state. The steam discharged from the exhaust end of the pneumatic rotary motor (52) then enters the second steam pipe (53) and the third steam pipe (54) in sequence and is delivered to the hollow rectangular block (1021) of the exhaust air knife assembly (102). The rotating rod (71) rotates continuously, causing the upper cam (72) and the lower cam (73) to rotate synchronously in the same direction. When the protruding part of the lower cam (73) rotates to push the lower top plate (101) of the upper air supply plate assembly (10), the lower top plate (101) slides upward along the support frame (744), causing the hollow rectangular block (1021) of the exhaust air knife assembly (102) to insert into the top groove hole (81) of the tray (8). At this time, the protruding part of the upper cam (72) rotates downward and is in a released state. The tray (8) falls downward instantly under its own weight and the elastic action of the telescopic elastic element (92), creating a clearance gap, allowing steam to enter the bottom of the breathable cloth bag. The arc surface at the top of the hollow rectangular block (1021) lifts up a local area at the bottom of the cloth bag to form an arc-shaped gap. Steam is sprayed out from the top surface and both sides of the exhaust groove (1022) at the same time, penetrating the cloth bag in all directions and entering the chili powder layer. After the rotating rod (71) continues to rotate half a turn, the protruding part of the upper cam (72) moves to the upper corner of the tray (8), and the tray (8) is pushed upward so that the bottom of the bag is separated from the hollow rectangular block (1021); at this time, the protruding part of the lower cam (73) moves downward and is in the released state, and the lower top plate (101) descends so that the hollow rectangular block (1021) exits the top slot hole (81), and the bag naturally falls back to the bottom of the tray (8); the telescopic elastic element (92) continues to generate residual elastic vibration during the falling and vibration of the tray (8), shaking the chili powder. For each rotation of the rotating rod (71), the upper cam (72) and the lower cam (73) complete one push and one release, repeating the above cycle until the set sterilization time ends; After the set sterilization time is reached, the steam boiler is depressurized, the pneumatic rotary motor (52) stops rotating, and the rotating rod (71) stops rotating. At this time, the two engaging blocks (741) that rotate with the rotating rod (71) stop at a certain position. The other engaging block (741) that is anti-rotation slidingly engaged with the fixed rod (743) is pushed by the first elastic element (742) to make the rotating engaging block (741) rotate in the opposite direction, which drives the rotating rod (71) and the upper cam (72) and lower cam (73) back to the initial phase, so that the hollow rectangular block (1021) exits the top slot hole (81) and the tray (8) can be pulled out. S3: During the sterilization process, hot and humid gas is discharged through the exhaust vent, check valve and exhaust fan (3) at the top of the outer heat insulation box (2). The control box (1) adjusts the exhaust fan (3) to maintain the humidity and pressure inside the box. After the set sterilization time is reached, the first steam pipeline (51) is closed, the pneumatic rotary motor (52) stops rotating, and each component automatically resets. After the temperature inside the box drops to a safe range, the outer heat insulation box (2) is opened, the tray (8) is pulled out using a trolley, and the sterilized cloth bag is taken out for subsequent drying and packaging processes.
