Description

Technical Field

[0001] This invention relates to the technical field of vegetable processing, and more specifically to a pasteurization line for vegetable processing. Background Technology

[0002] Vegetable sterilization is a common existing processing technology. To maintain and improve the shelf life of vegetables, the commonly used pasteurization production line, which uses standard temperature treatment, employs a high-temperature, short-time aging technique to denature proteins. However, due to the large size and high processing capacity of this type of production line, it has a better sterilization effect on heavier, solid vegetables. For vegetables with a core, the same treatment method may result in poor treatment of some grooves on the surface due to different soaking times. Extending the soaking time will cause the edges of the vegetables to ripen due to high temperatures, affecting the shelf life. Therefore, it is necessary to pick them out and soak them repeatedly, resulting in energy waste. Therefore, there is a need for a sterilization device that can identify vegetables and implement different sterilization strategies for different vegetables. Summary of the Invention

Several bent abutment plates are disposed at the end of the top cover plate near the feeding roller. The bent abutment plates have a bent plate structure and a sound capturing unit is disposed on the bent abutment plates to capture the sound of the sound wave emitter conducted by the vegetables.

A guide cover plate is provided at the end of the input cover plate near the top cover plate, and the input cover plate is hinged to one side of the guide cover plate. The side of the guide cover plate away from the input cover plate abuts against the inner cavity of the material trap groove.

[0007] In one embodiment, the liquid separator has a heat-insulating cavity in the middle to prevent direct heat conduction.

[0008] In one embodiment, the conveying component includes a rotating conveyor rod and a bending conveyor rod.

A top conveyor rod is provided on the side of the liquid-separating plate away from the feeding roller. The top conveyor rod passes through and is rotatably connected to the adjacent side plate. A second conveyor belt is wrapped around the outer sides of the top conveyor rod, the bending conveyor rod, and the rotating conveyor rod. Rotating bending wheels are provided on both sides of the outer end face of the second conveyor belt near the bending conveyor rod. The rotating bending wheels abut against the second conveyor belt, causing the second conveyor belt to bend near the bending conveyor rod. A rotating wheel rod is provided on the central axis of the rotating bending wheel. The rotating wheel rod passes through and is rotatably connected to the adjacent side plate. A plurality of conveying baffles are arranged in an array on the outer side of the second conveyor belt. A drive motor is provided on the side plate. The drive motor is used to drive the top conveyor rod to rotate and drive the second conveyor belt to move.

[0009] In one embodiment, a roller motor is provided on the outer periphery of the side plate, and the roller motor is used to drive the feeding roller to rotate along the axis.

[0010] In one embodiment, the liquid separator is further provided with transmission rotating rods on both sides, and two sets of transmission rotating rods are connected to the side plate through and rotatably. The outer sides of the two sets of transmission rotating rods are wrapped with a first transmission belt. The liquid separator is located between the annular first transmission belt. The outer side of the first transmission belt is provided with a plurality of arrayed material-pulling baffles. The side plate is also provided with a belt motor, which drives the transmission rotating rods to rotate and drive the first transmission belt to move.

[0011] In one embodiment, a filter element is provided on the side of the top transmission rod away from the first transmission belt, the filter element including a filter screen plate, the filter screen plate moving to abut against the isolation plate.

[0012] In one embodiment, the feeding roller is provided with an inclined guide plate on the side near the second conveyor belt. The inclined guide plate is used to assist the vegetables in the feeding roller to fall into the inclined guide plate and continue to fall above the second conveyor belt.

[0013] In one embodiment, the top cover plate is provided with a cooling liquid pipe, and the side plate is provided with a plurality of liquid extraction pipes. The liquid extraction pipe through hole is located in the middle of the side plate between the first transmission belt and the top cover plate. The middle of the side plate is also provided with a heating liquid pipe, which is located in the middle of the side plate between the second transmission belt and the first transmission belt.

[0014] The beneficial effects of this invention are as follows: This invention is a pasteurization line for vegetable processing with a simple structure that effectively identifies different vegetables while assisting in changing the sterilization strategy. The specific implementation method is as follows: The operator first feeds the vegetables through the input cover plate onto the hinged guide cover plate. The guide cover plate guides the vegetables into the feeding roller's recess. As the feeding roller rotates, the guide cover plate effectively overlaps with the recess, preventing vegetables from falling to the other side of the roller and avoiding leakage. Then, the roller motor is started to rotate the feeding roller. During this rotation, a sound wave transmitter is activated to emit sound waves. Since different vegetables have different shapes and structures, the specific implementation process is as follows: Solid vegetables, such as potatoes and tomatoes, have a higher density per unit volume than the sterilizing liquid. Due to their higher density, they have a slightly less effective at reducing sound waves during the transmission of sound waves by the sound wave transmitter than hollow vegetables. Therefore, when the feeding roller rotates, the vegetables in the material groove abut against the bent abutment plate, and the sound capturing unit receives the sound waves transmitted by the vegetables from the sound wave transmitter, the original intensity of the sound waves is not significantly changed. Thus, they can be considered solid vegetables. At this time, after the high-temperature liquid is introduced into the water storage chamber through the heat transfer pipe, the vegetables fall above the second conveyor belt due to gravity and the guiding effect of the inclined guide plate. Then, the transmission motor drives the top transmission rod to move the second conveyor belt so that the vegetables fall through the water storage chamber and above the filter plate within a specified time. The filter plate is then used to drain water for the next technical operation, such as drying. Water spinach, with a unit volume density lower than that of the sterilizing liquid (e.g., cabbage), has a low density and a complex internal structure with numerous grooves. This significantly weakens the sound waves transmitted by the sound wave transmitter. Therefore, when the feeding roller rotates, the vegetables in the grooves abut against the bent contact plate, and the sound capturing unit receives the sound waves transmitted by the vegetables, resulting in a significant change in the original intensity of the sound waves. Thus, it can be identified as a hollow vegetable. At this point, the heating pipe is activated to input high-temperature liquid until the water level reaches the insulated cavity, and then the process is completed. Low-temperature cooling liquid is introduced into the cold liquid supply pipe, and the extraction pipe is opened to draw out the mixed liquid. Even if the low-temperature liquid has a higher density, the amount falling into the high-temperature liquid area can be affected by the extraction pipe. At the same time, the flow rate of the cold liquid supply pipe and the hot liquid supply pipe is controlled to be less than the extraction rate of the extraction pipe, while the flow rate of the hot liquid supply pipe is kept greater than that of the cold liquid supply pipe. After the water spinach falls into the water storage chamber by the rotation of the feeding roller, the conveyor belt motor is started. The transmission action of the conveyor belt motor on the transmission rotating rod drives the feeding baffle on the first transmission belt to move the vegetables. After falling between the second conveyor belt and the first transmission belt, the hollow vegetables move against the lower surface of the first transmission belt due to their density, while being sterilized by the high-temperature liquid. Then, as the vegetables fall into the gap between the first and second transmission belts near the top transmission rod, they continue to fall into the cold water zone between the first transmission belt and the top cover plate for cooling, as the second conveyor belt is not rotating. Repeated rotation of the transmission rod causes the vegetables to circulate between the cold and hot water zones, passing through the hot water zone multiple times in short bursts, allowing the hot water to slowly penetrate into the gaps between the cabbages, ensuring sterilization while preventing overcooking. Once the desired effect is achieved, the first and second transmission belts are simultaneously activated, with the second conveyor belt's transmission speed slightly greater than the transmission rod. A feeding deflector at the gap between the first and second transmission belts pushes the vegetables onto a filter plate, allowing water to drain for the next technical operation, such as drying. For solid vegetables but of lower quality, when the sound capture unit receives the sound waves transmitted by the vegetable after the vegetable comes into contact with the bent contact plate, the attenuation effect is between the two types of vegetables mentioned above. Most of them have a thick outer skin, such as eggplant. Therefore, any of the above methods can achieve a solid effect. Excess mixed water can be directly filtered and added to the cold water zone after being extracted through the liquid extraction pipe, reducing energy waste.

[0015] This equipment has a simple structure and effectively utilizes the flow control of liquid in multiple tubes to achieve stratified temperature control in the water storage chamber. At the same time, it utilizes the structure of vegetables themselves to change the sterilization strategy, effectively reducing energy waste caused by multiple soakings, improving sterilization effect and avoiding overcooking. It has good practicality and economy, which is beneficial to the promotion and use of the equipment. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention; that is, the described embodiments are merely some embodiments of the invention, and not all embodiments. The components of the embodiments of the invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0021] The following is combined Figure 1-6 The following describes a specific embodiment of the present invention: a pasteurization line for vegetable processing includes a base plate 11, side plates 12 on both sides of the base plate 11, and an isolation plate 42 between the two sets of side plates 12. One side of the isolation plate 42 abuts against the base plate 11 to form a water storage cavity. An identification mechanism 1 is provided in the water storage cavity to identify the structure of the processed vegetables. A heat insulation component 2 is provided in the middle of the water storage cavity. The heat insulation component 2 includes a liquid-separating plate 24, which divides the water storage cavity into a low-temperature zone and a high-temperature zone. The side near the top cover plate 13 is the low-temperature zone. The liquid-separating plate 24 is located between the two sets of side plates 12. There is a gap between the two ends of the liquid-separating plate 24 and the isolation plate 42 to facilitate the falling and output of vegetables. A conveying component is provided in the water storage cavity to output vegetables into the water storage cavity. The identification mechanism 1 includes a feeding roller 14. Advantageously, a roller motor 144 is provided on the outer periphery of the side plate 12, driving the feeding roller 14 to rotate along its axis. The feeding roller 14 is positioned between the two sets of side plates 12, and has several material-collecting grooves 141. Each groove 141 contains a sound wave emitter 142, such as an ultrasonic transmitter or a loudspeaker, primarily used to transmit sound using vegetables as a medium or as a blocking medium. A top cover plate 13 is provided on the side of the two sets of side plates 12 away from the bottom plate 11. The top cover plate 13, near the feeding roller 14, has several bent abutment plates 143. These bent abutment plates 143 can be made of elastic metal for easy bending. The bending or restoring mechanism, with the bending abutment plate 143 having a bent plate structure, is equipped with a sound capture unit 1431 to capture the sound transmitted by the sound wave transmitter 142 through the vegetables, such as a microphone. By observing the sound changes caused by the sound wave transmitter 142 passing through the vegetables, the internal structure of the processed vegetables can be determined. For example, the sound attenuation effect of solid vegetables is lower than that of hollow vegetables, and the attenuation effect of vegetables with a core is particularly obvious. This facilitates the adoption of different sterilization strategies. At the same time, the identification method can be compared with the test results of various vegetables in the early stage, thereby controlling the movement rules of the equipment. This is an existing implementation technology, so it will not be described in detail. It is sufficient to use sound to identify vegetables and change the processing strategy. The attached figure is not shown.

[0022] Beneficially, the material trap 141 has a circumferential array structure, which facilitates batch feeding.

[0023] Beneficially, the side of the feeding roller 14 away from the top cover plate 13 is provided with an input cover plate 131. The two sides of the input cover plate 131 abut against the two sides of the adjacent side plate 12 away from the bottom plate 11. The end of the input cover plate 131 near the top cover plate 13 is provided with a guide cover plate 132. The side of the guide cover plate 132 is hinged to the input cover plate 131. The side of the guide cover plate 132 away from the input cover plate 131 abuts against the inner cavity of the material trap groove 141.

[0024] Beneficially, the liquid separator 24 has a heat-insulating cavity 25 in the middle to prevent direct temperature conduction. The heat-insulating cavity 25 can effectively prevent the temperature in the high-temperature zone from being conducted to the temperature in the low-temperature zone.

[0025] Beneficially, the conveying components include a rotary conveyor rod 261 and a bending conveyor rod 263. The rotary conveyor rod 261 and the bending conveyor rod 263 are located between the two sets of side plates 12 near the bottom plate 11. The rotary conveyor rod 261 and the bending conveyor rod 263 pass through and are rotatably connected to the side plate 12. A top conveyor rod 264 is provided on the side of the liquid separator 24 away from the feeding roller 14. The top conveyor rod 264 passes through and is rotatably connected to the adjacent side plate 12. A second conveyor belt 26 is wrapped around the outer side of the top conveyor rod 264, the bending conveyor rod 263, and the rotary conveyor rod 261. The second conveyor belt 26 is close to the bottom plate 11. Rotating bending wheels 266 are provided on both sides of the outer end face of the curved conveyor rod 263. The rotating bending wheels 266 abut against the second conveyor belt 26, so that the second conveyor belt 26 is bent near the bending conveyor rod 263. A rotating wheel rod 2661 is provided on the central axis of the rotating bending wheel 266. The rotating wheel rod 2661 passes through and is rotatably connected to the adjacent side plate 12. Several material conveying baffles 262 are arranged in an array on the outer side of the second conveyor belt 26. The specific number depends on the time situation. A drive motor 265 is provided on the side plate 12. The drive motor 265 is used to drive the top conveyor rod 264 to rotate and drive the second conveyor belt 26 to move.

[0026] Beneficially, the liquid separator 24 is also provided with transmission rotating rods 21 on both sides. The two sets of transmission rotating rods 21 pass through and are rotatably connected to the side plate 12. The outer sides of the two sets of transmission rotating rods 21 are wrapped with a first transmission belt 22. The liquid separator 24 is located between the annular first transmission belt 22. The outer side of the first transmission belt 22 is provided with several arrayed material-pushing baffles 23. The side plate 12 is also provided with a belt motor 211. The belt motor 211 drives the transmission rotating rods 21 to rotate and drive the first transmission belt 22 to move. Specifically, the top transmission rod 264 is provided with a filter element 4 on the side away from the first transmission belt 22. The filter element 4 includes a filter screen plate 41. The filter screen plate 41 moves to abut against the isolation plate 42.

[0027] Beneficially, the feeding roller 14 is provided with an inclined guide plate 121 on the side near the second conveyor belt 26. The inclined guide plate 121 is used to assist the vegetables in the feeding roller 14 to fall into the inclined guide plate 121 and continue to fall above the second conveyor belt 26.

[0028] Beneficially, the top cover plate 13 is provided with a cooling liquid pipe 133 for inputting cooling liquid, and the side plate 12 is provided with a number of liquid extraction pipes 135 for extracting mixed liquid. The through hole of the liquid extraction pipe 135 is located in the middle of the side plate 12 between the first transmission belt 22 and the top cover plate 13. The middle of the side plate 12 is also provided with a heat transfer liquid pipe 134 for inputting high-temperature liquid. The high-temperature liquid refers to the temperature required for sterilization. The heat transfer liquid pipe 134 is located in the middle of the side plate 12 between the second transmission belt 26 and the first transmission belt 22.

[0029] Working principle of this invention: The operator first places the vegetables through the surface of the input cover 131 onto the hinged guide cover 132. Guided by the guide cover 132, the vegetables fall into the feeding groove 141 of the feeding roller 14. The guide cover 132 effectively overlaps with the feeding groove 141 as the feeding roller 14 rotates, effectively preventing vegetables from falling to the other side of the feeding roller 14 and avoiding leakage. At this point, the roller motor 144 is started to rotate the feeding roller 14. During the rotation of the feeding roller 14, the sound wave transmitter 142 is activated to emit sound waves. Since different vegetables have different shapes and structures, the specific implementation process is as follows: Solid vegetables, such as potatoes and tomatoes, have a higher density per unit volume than the sterilizing liquid. Due to their higher density, their sound wave attenuation effect during sound wave transmission by the sound wave transmitter 142 is slightly less than that of hollow vegetables. Therefore, when the feeding roller 14 rotates, the vegetables in the trap 141 abut against the bent abutment plate 143, and the sound capturing unit 1431 receives the sound waves transmitted by the vegetables from the sound wave transmitter 142, the original intensity of the sound waves is changed little. Thus, they can be considered solid vegetables. At this time, after the high-temperature liquid is introduced into the water storage cavity through the heat transfer pipe 134, the vegetables fall above the second conveyor belt 26 due to gravity and the guiding effect of the inclined guide plate 121. Then, the transmission motor 265 drives the top transmission rod 264 to move the second conveyor belt 26 so that the vegetables fall above the filter plate 41 through the water storage cavity within a specified time. The filter plate 41 is then used to drain water for the next technical operation, such as drying. Water spinach, with a unit volume density lower than that of the sterilizing liquid (e.g., cabbage), has a low density and a complex internal structure with numerous grooves. This significantly reduces the sound wave intensity during transmission to the sound wave transmitter 142. Therefore, when the feeding roller 14 rotates, the sound capturing unit 1431 receives the sound waves transmitted by the vegetable from the sound wave transmitter 142 after the vegetable in the trap 141 abuts against the bent abutment plate 143, resulting in a significant change in the original intensity of the sound waves. Thus, it can be identified as a hollow vegetable. At this point, the heating pipe 134 is activated to input high-temperature liquid until the water level reaches the insulation cavity 25, after which the cooling pipe is activated. Low-temperature cooling liquid is introduced into the liquid pipe 133, and the liquid extraction pipe 135 is opened to extract the mixed liquid. Even if the low-temperature liquid has a high density, the amount falling into the high-temperature liquid area can be affected by the liquid extraction pipe 135. At the same time, the liquid flow rate of the cooling liquid pipe 133 and the heating liquid pipe 134 is controlled to be less than the extraction rate of the liquid extraction pipe 135, and the liquid flow rate of the heating liquid pipe 134 is kept greater than that of the cooling liquid pipe 133. After the water spinach falls into the water storage chamber by the rotation of the feeding roller 14, the conveyor motor 211 is started. The conveyor motor 211 drives the first conveyor belt 22 to move upwards by the transmission action of the conveyor rotating rod 21. After the feeding baffle 23 pushes the vegetables into the space between the second conveyor belt 26 and the first transmission belt 22, the hollow vegetables move against the lower surface of the first transmission belt 22 due to their density, and are simultaneously treated by the sterilization effect of the high-temperature liquid. Then, after the vegetables fall into the gap between the first transmission belt 22 and the second conveyor belt 26 near the top transmission rod 264, since the second conveyor belt 26 is not rotating, they continue to fall under the pushing force of other vegetables into the cold water zone between the first transmission belt 22 and the top cover plate 13 for cooling. At this time, the vegetables are cooled to prevent over-cooking. This process is repeated. The rotating conveyor 21 causes the vegetables to circulate between the cold and hot water zones, passing through the hot water zone multiple times in a short period of time. This allows the hot water to slowly penetrate into the gaps between the cabbages, ensuring a sterilization effect while preventing the vegetables from overcooking. Once the target effect is achieved, the first transmission belt 22 and the second transmission belt 26 are activated simultaneously. The transmission speed of the second transmission belt 26 is slightly greater than that of the rotating conveyor 21. The feeding deflector 262 at the gap between the first transmission belt 22 and the second transmission belt 26 pushes the vegetables onto the filter screen 41, where the water is drained for the next technical operation, such as drying. For solid vegetables but of lower quality, when the sound capturing unit 1431 receives the sound waves transmitted by the sound wave transmitter 142 after the vegetable comes into contact with the bent contact plate 143, the attenuation effect is between the two types of vegetables mentioned above. Most of the vegetables have a thick outer skin, such as eggplant. Therefore, any of the above methods can be used to achieve the effect. Excess mixed water can be directly filtered and added to the cold water zone after being extracted through the liquid extraction pipe 135, reducing energy waste.
