Description

Technical Field

[0001] The present invention relates to the technical field of steam boilers, and particularly to a high-temperature steam sterilization device for processing lamb shank bones. Background Art

[0002] A sterilization device is an efficient and professional airtight pressurized heating device, which is widely used in food processing, pharmaceuticals, medical treatment, agriculture and certain industrial fields for sterilizing food, drugs, agricultural products and industrial products to extend their shelf life or meet specific hygiene standards. The working principle of the sterilization device is based on the heat treatment principle. Through precise temperature control, steam or hot water is used as the heat transfer medium to heat up, sterilize and cool the material. In the heating-up stage, the steam or hot water is heated to a high temperature and high pressure state and evenly sprayed onto the material through a steam nozzle to quickly heat it up. In the sterilization stage, the material is kept in a high-temperature and high-pressure environment for a period of time to kill the microorganisms and bacteria therein. Finally, in the cooling stage, by controlling the flow rate and temperature of the cooling water, the material is gradually cooled to a safe temperature to avoid deformation or rupture of the material caused by too large a temperature difference.

[0003] In the prior art, direct sterilization is carried out using a steam pot, and the sterilization effect is often not good and different positions cannot be adjusted. Therefore, a sterilization device used in combination with a steam pot is needed to achieve the sterilization effect at different times and different positions. Summary of the Invention

[0004] In view of the above technical problems, the present invention discloses a high-temperature steam sterilization device for processing lamb shank bones, including an evaporation box. A steam assembly is installed in the evaporation box. The steam assembly includes an intermediate cylinder, which is fixedly installed in the evaporation box and has a gap with the bottom surface of the evaporation box. A breathable plate is fixedly installed in the intermediate cylinder. The steam generating device includes a steam pot, and a connecting pipe is connected to the upper end of the steam pot. A control valve is provided at the end of the control valve. The output end of the control valve is connected to a branch pipe two and a branch pipe one. The steam direction is controlled through the control valve to pass steam to different positions in the evaporation box.

[0005] Further, a ring-shaped nozzle is installed at the end of the branch pipe two. The ring-shaped nozzle is located below the intermediate cylinder. A straight nozzle is installed at the end of the branch pipe one, and the straight nozzle is installed on the side wall of the evaporation box.

[0006] Further, there is a gap between the ventilation plate and the bottom of the middle cylinder. Ventilation holes are provided on the side surface of the middle cylinder and the ventilation plate, and lamb shanks are placed on the ventilation plate. The control valve controls the position of the steam leading into the evaporation box at different times. The steam sterilizes the lamb shanks through the ventilation holes. At the beginning, the steam vents from the side to directly sterilize the lamb shanks. When the temperature in the evaporation box reaches the required level, the control valve controls the steam to lead to the second branch pipe. The steam heats the bottom of the middle cylinder through the annular spray head, enabling the condensed water in the middle cylinder to be heated and evaporated as well. In this way, the middle cylinder can also be steam-sterilized to a certain extent. Such a design can greatly increase the temperature and improve the sterilization efficiency. Such a cycle can avoid waste of heat, utilize the excess heat to continue heating and evaporating the condensed water falling into the middle cylinder, and reduce energy consumption.

[0007] Further, a top plate is fixedly installed on the upper part of the middle cylinder. Water is contained on the upper side of the top plate, and the top plate slopes downward from the center towards a direction away from the axis. Through the above technical solution, during high-temperature steaming and killing, the temperature at the upper end is often too high. Setting low-temperature water on the upper side of the top plate can ensure that the upper and lower temperatures in the middle cylinder are similar. Moreover, when the steam moves upward and encounters the top plate, it can accelerate condensation. The inclined setting also causes the water droplets to flow towards the surroundings and leave along the side wall of the middle cylinder, preventing the condensed water from directly dripping on the lamb shanks and affecting the sterilization effect.

[0008] Further, a connection is provided between the upper part of the middle cylinder and the evaporation box, and a return pipe is installed between the upper part of the middle cylinder and the steam boiler.

[0009] Further, a spiral plate is fixedly installed on the ventilation plate, and the lamb shanks stand upright and are arranged spirally outward within the spiral plate. Through the above technical solution, standing the lamb shanks up and placing them in the gaps of the spiral plate can greatly improve the space utilization rate. The compact vertical arrangement can also enable the steam to move more smoothly from bottom to top, minimizing the condensation of steam on the lamb shanks as much as possible;

[0010] Further, a connection component is installed on the evaporation box. The connection component penetrates to the upper side of the spiral plate, and a lever component is installed on the connection component. The lever component includes a cross beam. The cross beam is slidably installed at the output end of the connection component. A compression spring is fixedly installed between the first end of the cross beam and the output end of the connection component. A fixed rod is fixedly installed at the second end of the cross beam. A sleeve is installed below the fixed rod, a sliding rod is installed within the sleeve, an arc-shaped plate one is installed at the end of the sliding rod, a vertical rod is installed on the sliding rod, and an arc-shaped plate two is installed on the vertical rod.

[0011] Further, the sliding rod is slidably connected to the sleeve, the vertical rod is slidably connected to the sliding rod, a limiting piece is fixedly installed on the sliding rod, and the vertical rod slides between the limiting piece and the sleeve. When the vertical rod contacts the sleeve, the arc-shaped plate one is located at the front side. When the vertical rod contacts the limiting piece, the arc-shaped plate two is located at the front side.

[0012] Further, a lever spring is fixedly installed between the sliding rod and the sleeve.

[0013] Further, an auxiliary rod is fixedly installed on the vertical rod, and the auxiliary rod is slidably connected to the fixed rod. Through the above technical solution, the lever assembly can push the lamb shank bone to gradually move inward along the spiral plate. And initially, the lower side of the lamb shank bone is pushed first, so that the lamb shank bone tilts towards the lever assembly, and is supported by the second arc-shaped plate to ensure that it will not fall during the movement. And when it is pushed to the designated position, the bone can be tilted to the other side and leaned against the bone that has already been in place.

[0014] Further, a feeding assembly is installed at the upper end of the evaporation box. The feeding assembly includes a feeding channel, and lamb shank bones are arranged in the feeding channel from top to bottom. An elastic plate is fixedly installed at the lower end of the feeding channel.

[0015] Further, an intermediate plate is fixedly installed in the feeding channel. A notch is provided in the middle of the intermediate plate. A feeding rod is rotatably installed on the side of the feeding channel. The feeding rod is cross-shaped and rotates at the center of the cross. A bayonet is provided on each rod of the feeding rod. The width of the bayonet is greater than the middle diameter of the lamb shank bone, and the width of the bayonet is less than the diameters of both ends of the lamb shank bone.

[0016] The beneficial effects of the present invention compared with the prior art are as follows:

[0017] (1) Through the technical solution of the present invention, the valve is controlled to control the steam to different positions in the evaporation box at different times. The steam passes through the ventilation holes to sterilize the lamb shank bones. At the beginning, the steam vents from the side to directly sterilize the lamb shank bones. When the temperature in the evaporation box reaches the required temperature, the valve is controlled to make the steam flow to the branch pipe two. The steam passes through the annular nozzle to heat the bottom of the middle cylinder, so that the condensed water in the middle cylinder can also be heated and evaporated. In this way, the middle cylinder can also be sterilized by steam to a certain extent. Such a design can greatly increase the temperature and improve the sterilization efficiency. Such a cycle can avoid waste of heat and use the excess heat to continue heating and evaporating the condensed water falling into the middle cylinder, reducing energy consumption.

[0018] (2) Through the technical solution of the present invention, when performing high-temperature steaming and killing, the temperature at the upper end is often too high. Setting low-temperature water on the upper side of the top plate can ensure that the temperature in the middle cylinder is similar up and down. And the steam rising upwards meets the top plate and can accelerate condensation. The inclined setting will also make the water droplets flow around and leave along the side wall of the middle cylinder, preventing the condensed water from directly dripping on the lamb shank bones and affecting the sterilization effect. The condensed water in the middle cylinder will also be continuously heated. The steam at the top of the evaporation box will pass through the ventilation pipeline to the upper space of the middle cylinder, and then return to the steam pot through the return pipe for continuous heating to form a cycle. If there is too much water in the upper space of the middle cylinder or too little water in the steam pot, water can be directly pumped through the return pipe.

[0019] (3) Through the technical solution of the present invention, standing the lamb shank bones upright in the gaps of the spiral plate can greatly improve the space utilization rate. The compact arrangement in the upright state also enables the steam to move more smoothly from bottom to top, minimizing the condensation of steam on the lamb shank bones.

[0020] (4) Through the technical solution of the present invention, the lever component can push the lamb shank bones to gradually move inward along the spiral plate. And initially, the lower side of the lamb shank bones is pushed first, causing the lamb shank bones to tilt towards the direction close to the lever component, and being supported by the second arc-shaped plate to ensure that they will not fall during the movement. And when pushed to the specified position, the shank bones can be tilted to the other side and leaned against the shank bones that have already reached the position.

Detailed implementation manners

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

[0035] As Figures 1 - 12 shown, a high-temperature steam sterilization device for processing lamb shank bones includes an evaporation tank 5. A temperature detection system and an adjustment control system are provided in the evaporation tank 5. This is prior art and will not be shown in this embodiment. Four legs are fixedly installed at the four bottom corners of the evaporation tank 5 for support. The evaporation tank 5 is connected to a steam generating device 9 for high-temperature steam sterilization.

[0036] The steam generating device 9 includes a steam pot 901. A connecting pipe 902 is connected to the upper end of the steam pot 901. A control valve 903 is provided at the end of the control valve 903. The output end of the control valve 903 is connected to a second branch pipe 906 and a first branch pipe 904. The steam direction is controlled by the control valve 903. An annular spray head 907 is installed at the end of the second branch pipe 906. The annular spray head 907 is located below the intermediate cylinder 301. A straight spray head 908 is installed at the end of the first branch pipe 904. The straight spray head 908 is installed on the side wall of the evaporation tank 5.

[0037] In this embodiment, a steam assembly 3 is installed in the evaporation box 5. The steam assembly 3 includes an intermediate cylinder 301 which is fixedly installed in the evaporation box 5 with a gap left between it and the bottom surface of the evaporation box 5. The gap is used to install an annular nozzle 907 and also leaves a space for steam flow. The steam is sprayed towards the intermediate cylinder 301 and then moves around. An air-permeable plate 302 is fixedly installed in the intermediate cylinder 301 with a gap left between the air-permeable plate 302 and the bottom of the intermediate cylinder 301. Vent holes 303 are provided on the side surface of the intermediate cylinder 301 and the air-permeable plate 302, and water vapor can enter along the vent holes 303. The air-permeable plate 302 is placed with sheep leg bones. No vent holes 303 are provided at the bottom and near the bottom of the intermediate cylinder 301, and this position is also used to hold water. The condensed and refluxed water will enter the bottom of the intermediate cylinder 301 and then further evaporate in the intermediate cylinder 301. Through such a design, when the evaporation box 5 is passed with steam, the sheep leg bones can be sterilized at high temperature through the vent holes 303, and at the same time, water can be stored at the bottom of the intermediate cylinder 301 for evaporation and high-temperature sterilization. Such a design can greatly increase the temperature and improve the sterilization efficiency.

[0038] In this embodiment, a cover body 6 is installed at the top of the intermediate cylinder 301 for sealing and is fixed by a plurality of fixing devices 8. Pressure gauges 7 are installed on the tops of the evaporation box 5 and the cover body 6 for monitoring. A top plate 305 is fixedly installed on the upper part of the intermediate cylinder 301, and water is placed on the upper side of the top plate 305. The top plate 305 slopes downward from the center to a direction away from the axis. The steam rises and then encounters the top plate 305. Since there is low-temperature water on the upper side of the top plate 305, it is relatively cool, and condensed water will be formed on the lower side of the top plate 305. Since the top plate 305 is inclined, it will flow around and finally flow down along the side wall of the intermediate cylinder 301 to the bottom of the intermediate cylinder 301. During the process, it will pass through the air-permeable plate 302. Through the above technical solution, when performing high-temperature steam sterilization, the temperature at the upper end is often too high. Setting low-temperature water on the upper side of the top plate 305 can ensure that the upper and lower temperatures in the intermediate cylinder 301 are similar, and the steam rising and encountering the top plate 305 can accelerate condensation. The inclined setting will also make the water droplets flow around and leave along the side wall of the intermediate cylinder 301, preventing the condensed water from directly dripping on the sheep leg bones and affecting the sterilization effect. A ventilation pipeline 308 is connected between the upper part of the intermediate cylinder 301 and the evaporation box 5, and a return pipe 905 is installed between the upper part of the intermediate cylinder 301 and the steam pot 901.

[0039] The steam pot 901 generates steam, which enters the control valve 903 through the connecting pipe 902. In the initial stage, the control valve 903 controls the steam to lead to the first branch pipe 904. The steam sprays out from the straight nozzle 908 after passing through the first branch pipe 904. The steam sterilizes the lamb shanks through the ventilation holes 303. When the temperature in the evaporation box 5 reaches the required level, a certain amount of condensed water also accumulates at the bottom of the middle cylinder 301. The control valve 903 controls the steam to lead to the second branch pipe 906. The steam heats the bottom of the middle cylinder 301 through the annular nozzle 907, enabling the condensed water in the middle cylinder 301 to be heated and evaporated as well. The return pipe 905 is installed between the upper part of the middle cylinder 301 and the steam pot 901, and the water on the upper side of the middle cylinder 301 is pumped back into the steam pot 901 for evaporation through the pump body.

[0040] In this embodiment, a spiral plate 304 is fixedly installed on the air-permeable plate 302, and the lamb shanks are arranged spirally outward within the spiral plate 304. The pitch of the spiral plate 304 is uniform, and the gaps formed therein are adapted to the size of the lamb shanks. Lamb shanks that are slightly larger can enter, and those that are slightly smaller will tilt but not fall. Through the above technical solution, placing the lamb shanks upright in the gaps of the spiral plate 304 can greatly improve the space utilization rate. The compact vertical arrangement also enables the steam to move more smoothly from bottom to top, minimizing the condensation of steam on the lamb shanks as much as possible. Start the heating system in the evaporation box 5, and the temperature in the evaporation box 5 gradually rises, and then sterilization begins. The steam enters the middle cylinder 301 through the ventilation holes 303 to perform high-temperature sterilization on the lamb shanks on the air-permeable plate 302. The water vapor continues to rise and will condense when it encounters the top plate 305. The condensed water flows around and returns to the top of the middle cylinder 301. After a period of time, a certain amount of water also accumulates in the middle cylinder 301. At this time, the steam direction is switched through the control valve 903, and the steam sprays against the bottom of the middle cylinder 301, and then the condensed water can be evaporated again, enabling simultaneous evaporation in two layers. The steam at the top of the evaporation box can return to the steam pot 901 through the ventilation pipeline 308 and the return pipe 905 to form a cycle. If there is too much water in the upper space of the middle cylinder 301 or too little water in the steam pot 901, the water in the upper space of the middle cylinder 301 can be directly pumped into the steam pot 901 through the return pipe 905, and a pump body is set for pumping. A small amount of water is initially installed in the upper space of the middle cylinder 301, and condensed water will also be present during subsequent use.

[0041] In this embodiment, a connection assembly 2 is installed on the evaporator box 5. The connection assembly 2 penetrates to the upper side of the spiral plate 304. A lever assembly 1 is installed on the connection assembly 2. The connection assembly 2 includes a gear box 208. The gear box 208 is fixedly installed at the bottom end of the evaporator box 5. One end of the gear box 208 is controlled by a driving motor 209. The other end of the gear box 208 is fixedly equipped with a lower layer rod 206. The lower layer rod 206 passes through the middle cylinder 301 and the ventilation plate 302. A protective cylinder 207 is fixedly installed between the middle cylinder 301 and the evaporator box 5. The lower layer rod 206 is located inside the protective cylinder 207. The protective cylinder 207 is used to protect the lower layer rod 206 because there is high-temperature water vapor in the middle cylinder 301, and the protective cylinder 207 plays a role in isolating the water vapor. A groove 204 is provided at the upper end of the lower layer rod 206, and the center of the lower layer rod 206 is a mating hole 205. Matched with the lower layer rod 206 is an upper layer rod 201. A protruding block 202 and a thin shaft 203 are fixedly installed at the lower end of the upper layer rod 201. The protruding block 202 is inserted into the mating hole 205 while the thin shaft 203 just fits with the groove 204. The upper layer rod 201 is the output end of the connection assembly 2. The lever assembly 1 is connected to the upper layer rod 201.

[0042] In this embodiment, the lever assembly 1 includes a cross beam 112. The cross beam 112 is slidably mounted on the output end of the connection assembly 2, that is, the upper rod 201. A compression spring 114 is fixedly installed between the first end of the cross beam 112 and the upper rod 201. Specifically, a spring piece 113 is fixedly installed at the first end of the cross beam 112, and a compression spring 114 is fixedly installed between the spring piece 113 and the upper rod 201. A fixing piece 111 is fixedly installed at the second end of the cross beam 112. A fixing rod 101 is detachably installed on the fixing piece 111. The fixing rod 101 is inserted into the cross beam 112, and then the fixing piece 111 and the fixing rod 101 are fixed together by bolts. The size of the fixing piece 111 is larger than the hole on the cross beam 112, so it will be stuck, and at this time, fixation is formed, which is also convenient for disassembly. The fixing rod 101 is fixedly connected to the cross beam 112 through the fixing piece 111. A sleeve 102 is installed below the fixing rod 101. A sliding rod 103 is slidably installed in the sleeve 102. An arc-shaped plate one 106 is installed at the end of the sliding rod 103. A vertical rod 104 is slidably installed on the sliding rod 103. An arc-shaped plate two 107 is installed on the vertical rod 104; a limiting piece 105 is fixedly installed on the sliding rod 103. The vertical rod 104 slides between the limiting piece 105 and the sleeve 102. When the vertical rod 104 contacts the sleeve 102, the arc-shaped plate one 106 is located at the front side. When the vertical rod 104 contacts the limiting piece 105, the arc-shaped plate two 107 is located at the front side (the front side in this embodiment refers to the moving direction when the lever assembly 1 transports the lamb shank bone towards the center); a lever spring 110 is fixedly installed between the sliding rod 103 and the sleeve 102; an auxiliary rod 108 is fixedly installed on the vertical rod 104. The auxiliary rod 108 is slidably connected to the fixing rod 101. A limiting head 109 is fixedly installed at the end of the auxiliary rod 108 to prevent the auxiliary rod 108 from slipping off the fixing rod 101. Through the above technical solution, the lever assembly 1 can push the lamb shank bone to gradually move inwards along the spiral plate 304. And initially, the lower side of the lamb shank bone is pushed first, so that the lamb shank bone tilts towards the direction close to the lever assembly 1, and is supported by the arc-shaped plate two 107 to ensure that it will not fall during the movement. And when it is pushed to the specified position, the shank bone can be tilted to the other side and leaned against the shank bone that has already reached the position.

[0043] In this embodiment, a feeding assembly 4 is installed at the upper end of the evaporation box 5. The entire feeding assembly 4 is slightly inclined, with the lower end close to the front (in this embodiment, the front side refers to the direction in which the lever assembly 1 transports the lamb shanks towards the center). The feeding assembly 4 includes a feeding channel 401. The lamb shanks are arranged vertically in the feeding channel 401 from top to bottom. An elastic plate 406 is fixedly installed at the lower end of the feeding channel 401. The inner dimension of the feeding channel 401 also adapts to the lamb shanks. Slightly larger lamb shanks are vertical in the feeding channel 401, and slightly smaller lamb shanks are slightly inclined in the feeding channel 401, but they can only be arranged one by one from top to bottom. When the lamb shanks are placed down, gravity will open the elastic plate 406. The elastic plate 406 has elasticity and returns to its original state after the lamb shanks leave to continue blocking the lower opening of the feeding channel 401.

[0044] In this embodiment, an intermediate plate 407 is fixedly installed in the feeding channel 401. A notch is provided at the middle position of the intermediate plate 407. A feeding rod 402 is rotatably installed on the side of the feeding channel 401. The feeding rod 402 is cross-shaped. The main reason for setting it as cross-shaped is that it can just form a cooperation with the lamb shanks. If the length of the feeding rod 402 increases, multiple feeding rods 402 can also be set and do not have to be cross-shaped, and they rotate around the center of the cross. A central shaft 404 is rotatably installed on the feeding channel 401. The central shaft 404 is fixedly connected to the center of the feeding rod 402. The central shaft 404 is controlled to rotate by a feeding motor 405. A bayonet 403 is provided on each rod of the feeding rod 402. The width of the bayonet 403 is greater than the middle diameter of the lamb shank, and the width of the bayonet 403 is less than the diameters at both ends of the lamb shank. Through the above technical solution, the middle position of the lamb shank is stuck in the bayonet 403, and then the upper end of the lamb shank is located on the feeding rod 402 and cannot move downwards. Rotating the feeding rod 402 can lower one lamb shank, and then the other feeding rods 402 and bayonets 403 can also hold the upper lamb shanks, ensuring that only one lamb shank drops each time.

[0045] Working principle: Start the steam boiler 901, control the valve 903 to supply steam to the evaporation chamber 5. The steam is ejected from the straight nozzle 908, water is added to the top plate 305, the cover body 6 is installed, and the steam enters the lamb shanks through the ventilation holes 303 for high-temperature sterilization. The water vapor condenses on the lower side of the top plate 305, and the water droplets flow around and fall along the middle cylinder 301 to the bottom end of the middle cylinder 301. During this process, it passes through the small notch 306, and then the water in the middle cylinder 301 also starts to evaporate. When the temperature in the evaporation chamber reaches the preset value, switch the steam direction, and spray steam on the bottom of the middle cylinder 301 through the annular nozzle 907. At this time, the condensed water in the middle cylinder 301 is evaporated. Finally, the sterilization is completed. After that, open the cover body 6, remove the top plate 305, remove the lever assembly 1, take out the upper rod 201 upward together, and then the air-permeable plate 302, the spiral plate 304 and the lamb shanks above can be taken out. There is a large notch 307 on the air-permeable plate 302. When moving upward, the large notch 307 faces the feeding assembly 4 and will not be blocked.

[0046] Before starting steam sterilization, first place the lamb shanks in the feeding channel 401. The feeding channel 401 can be set longer. Then start the feeding motor 405. The feeding motor 405 drives the feeding rod 402 to rotate 90 degrees. At this time, the lowermost lamb shank drops, and the rotated feeding rod 402 of the other side catches the upper lamb shank through the bayonet 403. The dropped lamb shank pushes open the elastic plate 406 and lands on the middle cylinder 301. Since the entire feeding assembly 4 is inclined, the lamb shanks will also rest on the arc plate one 106 and the arc plate two 107 when falling and will not fall in the wrong direction. Start the driving motor 209. The driving motor 209 drives the mating hole 205, the upper rod 201, and the cross beam 112 through the gearbox 208. The cross beam 112 drives the fixed rod 101. The fixed rod 101 pushes the sleeve 102 through the lever spring 110. The sleeve 102 pushes the arc plate one 106. The arc plate one 106 pushes the bottom end of the lamb shank. At this time, since the vertical rod 104 and the sliding rod 103 are connected interactively, at the beginning, the vertical rod 104 will not move due to the friction of the spiral plate 304 until the vertical rod 104 contacts the sleeve 102. The sleeve 102 drives the vertical rod 104 to move. At this time, the arc plate one 106 is located in front of the arc plate two 107, and the lower end of the lamb shank moves forward obliquely and will not fall. During this process, the cross beam 112 slides on the upper rod 201. After moving to the specified position, the lower end of the lamb shank can no longer move. At this time, the sliding rod 103 squeezes the lever spring 110, and the sleeve 102 will drive the vertical rod 104 and the arc plate two 107, and the upper end of the lamb shank continues to move until the upper end of the lamb shank tilts forward and leans on the previous lamb shank. Then the driving motor 209 rotates in reverse to drive the lever assembly 1 to return to its original position, and the feeding assembly 4 also sends down another lamb shank. This process is repeated until the spiral plate 304 is filled.
