Description

Technical Field

[0001] This invention belongs to the field of high-temperature sterilization technology for packaging cans, specifically a high-temperature sterilization and disinfection device for food packaging cans. Background Technology

[0002] Canned food refers to food made by processing, blending, canning, sealing, sterilizing, cooling, and aseptically filling qualified raw materials to achieve commercial sterility requirements. It can be stored at room temperature for a long time without preservatives. Canned yellow peaches are a type of canned food made from yellow peaches; they are rich in vitamin C, fiber, and carotene, which are essential for the human body. They can generally be eaten directly after opening or heated at high temperatures. In hot summers, canned yellow peaches taste even better after being refrigerated. Sterilization is required during the production of canned food.

[0003] A patent with announcement number CN204560804U discloses a high-efficiency, energy-saving, water-saving, ultra-high temperature delayed sterilization device, including a left sterilization vessel, a right sterilization vessel, a feeding tank, a front heat exchanger, a homogenizer, a preparation tank, a rear heat exchanger, a filling machine, a cold water tank, and an insulated water tank. The feeding tank is connected to the inlet of one channel of the front heat exchanger, and the outlet of this channel is connected to both the left and right sterilization vessels via the homogenizer. The left and right sterilization vessels are also connected to the inlet of another channel of the front heat exchanger, and the outlet of this channel is connected to the preparation tank. This invention achieves: ① thorough sterilization; ② energy and water conservation; ③ cost savings in packaging.

[0004] Currently, existing packaging cans require high-temperature sterilization of up to 120 degrees Celsius for 40 minutes each time. This results in the inside of the sterilization can being constantly under high temperature and pressure, and the surface of the packaging can being constantly under high temperature. Employees need to pull the packaging cans out of the sterilization device, and the high-temperature steam remaining inside the sterilization can and the high temperature remaining on the surface of the packaging can cause burns to the employees.

A transmission rod is fixedly connected to the output end of the electric motor. Multiple sets of bidirectional threaded layers are formed on the outer surface of the transmission rod. A sealing plate is fixedly installed on the bottom surface of the overlapping support plate. A shim strip is fixedly connected to the top surface of the sealing plate. A food packaging can is movably sleeved on the top surface of the shim strip. An arc-shaped butt strip is movably sleeved on the outer surface of the bidirectional threaded layer.

[0008] Preferably, a limiting rod is fixedly connected to the outer surface of the docking plate, and a docking groove is provided on the inner wall of the docking plate, which is movably sleeved on the outer surface of the limiting rod.

[0009] Preferably, a hollow tube is fixedly connected to one side surface of the transmission plate, the outer surface of the hollow tube extends to the inner wall of the overlapping support plate, an outwardly extending hollow sleeve is fixedly installed on the upper and lower sides of the high-temperature sterilization tank, and one end of the hydraulic rod is fixedly installed on the inner wall of the outwardly extending hollow sleeve.

[0010] Preferably, a limiting collar that is fixedly connected to the top surface of the overlapping support plate is movably sleeved on the outer surface of the bidirectional threaded layer and located in the middle position, and an exhaust pipe is provided on the top surface of the sealing plate.

[0011] Preferably, a support frame is fixedly connected to the bottom surface of the high-temperature sterilization tank, and two sets of dry high-temperature heaters are fixedly installed on the outer surface of the support frame.

[0012] Preferably, a high-temperature gas guide pipe is fixedly connected to the output end of the dry high-temperature heater, and a transmission ring is fixedly connected to one end of a set of high-temperature gas guide pipes.

[0013] Preferably, one end of the transmission ring is movably sleeved on the outer surface of the transmission plate, and one end of the other set of high-temperature air guide pipes extends to the inner wall of the high-temperature sterilization tank.

[0014] Preferably, a track is provided at the bottom edge of the high-temperature sterilization tank, and a conveyor belt is provided on the inner wall of the track.

[0015] Preferably, a lifter is fixedly installed on both sides of the track bar, and a hydraulic rod is fixedly connected to the output end of the lifter. A lifting and sealing cover that is sealed and overlapped on the bottom surface of the high-temperature sterilization tank is movably sleeved on the output end of the hydraulic rod, and a packaging tank storage box is provided on the top surface of the lifting and sealing cover.

[0016] Preferably, a motor is fixedly installed on the outer surface of the outward hollow shell, a swing arm is fixedly connected to the output end of the motor, and a sealing cover is movably sleeved on the other end of the swing arm.

[0017] The beneficial effects of this invention are as follows: 1. The high-temperature sterilization and disinfection device for food packaging cans of the present invention involves placing the packaging cans sequentially into the interior of the docking plate, and limiting the position of the packaging cans by means of the overlapping plate. After the packaging cans are limited, the docking plate is slowly pulled back by means of a hydraulic rod. The large slots on the surface of the overlapping support plate allow the falling packaging cans to slide into the interior of the overlapping support plate, thus initially limiting the position of the packaging cans and avoiding the situation where employees need to extend their arms into the high-temperature sterilization can and suffer burns from the high temperature. 2. The high-temperature sterilization and disinfection device for food packaging cans described in this invention, when the food packaging can falls into the overlapping support plate, is raised by a shim strip, leaving a certain gap between the food packaging can and the sealing plate. The electric motor rotates the transmission rod, which in turn drives two sets of arc-shaped connecting strips to move in opposite directions, so that the arc-shaped connecting strips are tightly engaged with the outer surface of the food packaging can. The clamping of the two sets of arc-shaped connecting strips firmly confines the food packaging can inside the overlapping support plate, preventing the food packaging can inside the overlapping support plate from falling off due to the rotation of the transmission plate. 3. The high-temperature sterilization and disinfection device for food packaging cans described in this invention comprises multiple sets of overlapping support plates that are internally clamped to the food packaging cans. Then, a motor rotates the transmission plate. At this time, a dry high-temperature heater injects high-temperature steam into the exhaust pipe. The high-temperature steam that is sprayed out will impact the inner wall of the food packaging can, sterilizing the inside of the food packaging can. At the same time, excess hot air will be discharged through the gaps on the bottom surface of the food packaging can. The rapid flow of hot steam can keep the inside of the food packaging can at a high temperature. Excess hot steam will accumulate and fill the inside of the high-temperature sterilization tank, sterilizing the outer surface of the food packaging can at a high temperature. 4. The high-temperature sterilization and disinfection device for food packaging cans described in this invention is equipped with a motor to rotate a transmission plate, causing the overlapping support plate to rotate inside the high-temperature sterilization can. At this time, a dry high-temperature heater is used to inject hot steam into the high-temperature gas duct. Meanwhile, a transmission ring on one end of the high-temperature gas duct is movably connected to the surface of the transmission plate, and the hot steam injected into the transmission ring is injected into the interior of the food packaging can through a hollow tube. The rotation of the hollow tube allows the rising hot steam to effectively enter the interior of the food packaging can. 5. The high-temperature sterilization and disinfection device for food packaging cans of the present invention, after the food packaging cans are sterilized, the electric motor on the surface of the bottom overlapping support plate rotates the bidirectional threaded layer, causing the arc-shaped connecting strip to swing to both sides, and causing the food packaging cans to fall vertically into the interior of the packaging can storage box plate. At this time, the lifting device is used to lower the lifting and sealing cover, so that the lifting and sealing cover overlaps on the top surface of the conveyor belt. At this time, the hydraulic rod two is used to retract, and the conveyor belt is used to move the lifting and sealing cover. After replacing the new lifting and sealing cover, the lifting device and the hydraulic rod two are used to fix and raise and lower the lifting and sealing cover. Attached Figure Description

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 7 As shown, a high-temperature sterilization and disinfection device for food packaging cans according to an embodiment of the present invention includes a high-temperature sterilization tank 12. A hydraulic rod 122 is fixedly installed on the inner walls of the upper and lower sides of the high-temperature sterilization tank 12. A docking plate 123 is fixedly connected to the output end of the hydraulic rod 122. An overlapping plate 126 is provided on the bottom inner wall of the docking plate 123. A motor 127 is fixedly installed on one side surface of the high-temperature sterilization tank 12. A transmission plate 128 is fixedly connected to the output end of the motor 127 and is movably sleeved on the inner wall of the high-temperature sterilization tank 12. An overlapping support plate 1210 is fixedly connected to the outer surface of the transmission plate 128. An electric motor c1 is fixedly installed on the top surface of the overlapping support plate 1210. A transmission rod c2 is fixedly connected to the output end of the electric motor c1. Multiple sets of bidirectional threaded layers c3 are opened on the outer surface of the transmission rod c2. A sealing plate c7 is fixedly installed on the bottom surface of the overlapping support plate 1210. A shim c8 is fixedly connected to the top surface of the sealing plate c7. A food packaging can c6 is movably sleeved on the top surface of the shim c8. An arc-shaped butt strip c5 is movably sleeved on the outer surface of the bidirectional threaded layer c3.

[0023] The packaging cans are placed into the docking plate 123 one by one, and the position of the packaging cans is limited by the overlapping plate 126. After the packaging cans are limited, the docking plate 123 is slowly pulled back with the hydraulic rod 122. The large slot on the surface of the overlapping support plate 1210 allows the falling packaging cans to slide into the overlapping support plate 1210, thus initially limiting the position of the packaging cans and avoiding the situation where employees have to extend their arms into the high-temperature sterilization tank 12 and get burned by the high temperature. When the food packaging can c6 falls into the overlapping support plate 1210, it is raised by the shim strip c8, leaving a gap between the food packaging can c6 and the sealing plate c7. The electric motor c1 rotates the transmission rod c2, which in turn drives the two sets of arc-shaped connecting strips c5 to move in opposite directions. The arc-shaped connecting strips c5 are tightly engaged with the outer surface of the food packaging can c6. The clamping of the two sets of arc-shaped connecting strips c5 firmly confines the food packaging can c6 inside the overlapping support plate 1210, preventing the food packaging can c6 from falling out of the overlapping support plate 1210 due to the rotation of the transmission plate 128. After the food packaging can c6 is secured inside the multiple sets of overlapping support plates 1210, the transmission plate 128 is rotated by the motor 127. At this time, the dry high-temperature heater 14 injects high-temperature steam into the exhaust pipe c9. The released high-temperature steam impacts the inner wall of the food packaging can c6, sterilizing the inside of the food packaging can c6. At the same time, excess hot air is discharged through the gaps on the bottom surface of the food packaging can c6. The rapid flow of hot steam keeps the inside of the food packaging can c6 at a high temperature. Excess hot steam accumulates and fills the inside of the high-temperature sterilization tank 12, sterilizing the outer surface of the food packaging can c6 at high temperature.

[0024] like Figures 1 to 7As shown, a limiting rod 124 is fixedly connected to the outer surface of the docking plate 123. A docking groove 125 is provided on the inner wall of the docking plate 123, which is movably fitted onto the outer surface of the limiting rod 124. A hollow tube 129 is fixedly connected to one side surface of the transmission plate 128. The outer surface of the hollow tube 129 extends to the inner wall of the overlapping support plate 1210. A limiting collar c4 is movably fitted onto the outer surface of the bidirectional threaded layer c3 and located in the middle position, and is fixedly connected to the top surface of the overlapping support plate 1210. An exhaust pipe c9 is provided on the top surface of the sealing plate c7. A support frame 11 is fixedly connected to the bottom surface of the high-temperature sterilization tank 12. Two sets of dry high-temperature heaters 1 are fixedly installed on the outer surface of the support frame 11. 4. A high-temperature gas guide pipe 141 is fixedly connected to the output end of the dry high-temperature heater 14. A transmission ring 142 is fixedly connected to one end of a set of high-temperature gas guide pipes 141. One end of the transmission ring 142 is movably sleeved on the outer surface of the transmission plate 128. One end of another set of high-temperature gas guide pipes 141 extends to the inner wall of the high-temperature sterilization tank 12. An outwardly extending hollow shell 121 is fixedly installed on the upper and lower surfaces of the high-temperature sterilization tank 12. One end of the hydraulic rod 122 is fixedly installed on the inner wall of the outwardly extending hollow shell 121. A motor a1 is fixedly installed on the outer surface of the outwardly extending hollow shell 121. A swing arm a2 is fixedly connected to the output end of the motor a1. A sealing cover a3 is movably sleeved on the other end of the swing arm a2.

[0025] After the food packaging can c6 is secured inside the overlapping support plate 1210, the swing arm a2 is rotated by the motor a1, and the sealing cover a3 on the outer surface of the swing arm a2 swings due to its own weight and balance force, so that the sealing cover a3 overlaps and seals the top surface of the high temperature sterilization tank 12. At this time, the interior of the high temperature sterilization tank 12 is completely sealed, reducing the escape of high temperature steam inside, thus achieving the effect of limiting the high temperature. The motor 127 rotates the transmission plate 128, causing the overlapping support plate 1210 to rotate inside the high-temperature sterilization tank 12. At this time, the dry high-temperature heater 14 injects hot steam into the high-temperature gas pipe 141. The transmission ring 142 on one end of the high-temperature gas pipe 141 is movably connected to the surface of the transmission plate 128, and the hot steam injected into the transmission ring 142 is injected into the food packaging tank c6 through the hollow tube 129. The rotation of the hollow tube 129 allows the rising hot steam to effectively enter the food packaging tank c6.

[0026] like Figures 1 to 4 and Figure 8As shown, a track bar 13 is provided at the bottom edge of the high-temperature sterilization tank 12. A conveyor belt 131 is provided on the inner wall of the track bar 13. A lifter 132 is fixedly installed on both sides of the track bar 13. A hydraulic rod 133 is fixedly connected to the output end of the lifter 132. A lifting and sealing cover 134, which is sealed and overlapped on the bottom surface of the high-temperature sterilization tank 12, is movably sleeved on the output end of the hydraulic rod 133. A packaging tank storage box plate 135 is provided on the top surface of the lifting and sealing cover 134.

[0027] After the food packaging can c6 has been sterilized, the electric motor c1 on the surface of the bottom overlapping support plate 1210 rotates the bidirectional threaded layer c3, causing the arc-shaped connecting strip c5 to swing to both sides, and causing the food packaging can c6 to fall vertically into the packaging can storage box plate 135. At this time, the lifting device 132 lowers the lifting and sealing cover 134, so that the lifting and sealing cover 134 overlaps the top surface of the conveyor belt 131. At this time, the hydraulic rod 133 retracts, and the conveyor belt 131 moves the lifting and sealing cover 134. After replacing the new lifting and sealing cover 134, the lifting device 132 and the hydraulic rod 133 fix and raise and lower the lifting and sealing cover 134.

[0028] Working principle: Packaging cans are placed into the docking plate 123 one by one, and the position of the packaging cans is limited by the overlapping plate 126. After the packaging cans are limited, the docking plate 123 is slowly pulled back by the hydraulic rod 122. The large slots on the surface of the overlapping support plate 1210 allow the falling packaging cans to slide into the overlapping support plate 1210, thus initially limiting the position of the packaging cans and avoiding the situation where employees need to extend their arms into the high-temperature sterilization tank 12 and suffer burns from the high temperature. When the food packaging can c6 falls into the overlapping support plate 1210, it is raised by the shim strip c8, leaving a gap between the food packaging can c6 and the sealing plate c7. The electric motor c1 rotates the transmission rod c2, which in turn drives the two sets of arc-shaped connecting strips c5 to move in opposite directions. The arc-shaped connecting strips c5 are tightly engaged with the outer surface of the food packaging can c6. The clamping of the two sets of arc-shaped connecting strips c5 firmly confines the food packaging can c6 inside the overlapping support plate 1210, preventing the food packaging can c6 from falling out of the overlapping support plate 1210 due to the rotation of the transmission plate 128. After the food packaging can c6 is secured inside the multiple sets of overlapping support plates 1210, the transmission plate 128 is rotated by the motor 127. At this time, the dry high-temperature heater 14 injects high-temperature steam into the exhaust pipe c9. The high-temperature steam that is sprayed out will impact the inner wall of the food packaging can c6, sterilizing the inside of the food packaging can c6. At the same time, excess hot air will be discharged through the gaps on the bottom surface of the food packaging can c6. The rapid flow of hot steam can keep the inside of the food packaging can c6 at a high temperature. Excess hot steam will accumulate and fill the inside of the high-temperature sterilization tank 12, sterilizing the outer surface of the food packaging can c6 at high temperature. After the food packaging can c6 has been sterilized, the electric motor c1 on the surface of the bottom overlapping support plate 1210 rotates the bidirectional threaded layer c3, causing the arc-shaped connecting strip c5 to swing to both sides, and causing the food packaging can c6 to fall vertically into the packaging can storage box plate 135. At this time, the lifting device 132 lowers the lifting and sealing cover 134, so that the lifting and sealing cover 134 overlaps the top surface of the conveyor belt 131. At this time, the hydraulic rod 133 retracts, and the conveyor belt 131 moves the lifting and sealing cover 134. After replacing the new lifting and sealing cover 134, the lifting device 132 and the hydraulic rod 133 fix and raise and lower the lifting and sealing cover 134.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
