Description

Technical Field

[0001] This invention relates to the field of sterilization equipment technology in canned food production, specifically a sterilization device for the production process of canned fruit. Background Technology

[0002] The sterilization device in the fruit canning production process is used in the fruit canning process. After the fruit is filled and sealed, it is sterilized to inhibit the growth of microorganisms and ensure the quality stability of the fruit cans within the specified shelf life.

[0003] Patent application CN201811654878.1 discloses a sterilization device in the production process of fruit canning, including a base, a hydraulic cylinder on the base, a sliding groove on the base, a roller at the lower end of the hydraulic cylinder, the roller being slidably connected to the sliding groove, a first handle fixedly connected to the hydraulic cylinder, a turntable at the upper end of the piston rod of the hydraulic cylinder, a transition plate on the turntable, a rotating groove on the transition plate, the turntable being rotatably connected to the rotating groove, a sealing cap fixedly connected to the lower end of the transition plate, and a resistance thermometer on the sealing cap.

[0004] However, during the steam spray sterilization process of fruit canned goods, the static stacking of the cans leads to uneven heat distribution. The cans located in the central area of ​​the equipment are blocked by the outer cans, resulting in low heating efficiency for the cans in the central area, while the cans in the edge areas are directly exposed to the high-speed steam flow and are heated intensely. This results in differences in the actual effective sterilization time of the cans, thus slowing down the overall sterilization time of the cans. Summary of the Invention

[0005] The purpose of this invention is to provide a sterilization device in the fruit canning process to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a sterilization device in the production process of fruit canning, comprising a spray chamber, wherein a supporting material channel is fixedly connected to the inner wall of the spray chamber, a motor is fixedly connected to the outer wall of the spray chamber, and a flow guiding mechanism is provided inside the spray chamber. The flow guiding mechanism includes a rotating drum. The outer wall of the rotating drum is rotatably connected to the inner wall of the spray chamber via bearings. The outer wall of the rotating drum is driven by a synchronous belt connected to the output end of a motor. The outer wall of the rotating drum has flow guiding holes, and the inner wall of the rotating drum is fixedly connected to a nozzle. The nozzle communicates with the flow guiding holes and is used to guide steam to spray the canned goods. A flow guiding blade is fixedly connected to the inner wall of the rotating drum. The flow guiding blade is used to guide steam. The flow guiding mechanism generates a swirling flow of steam, which can quickly flow through the gaps between the cans to the cans located in the central area. This allows the steam in the central area to heat up rapidly and maintain a consistent temperature with the steam in the outer area, reducing the difference in the actual effective sterilization time between the inner and outer areas of the cans. This reduces the overall sterilization time of the canning equipment and keeps the internal steam temperature of the equipment consistent, preventing the steam temperature from dropping during the spray diffusion process and causing insufficient sterilization time for the cans in the surrounding areas. This increases the stability of the canning equipment in sterilizing the cans.

[0007] According to the above technical solution, the inner wall of the spray chamber is provided with a flow guiding cavity, and the outer wall of the spray chamber is fixedly connected with a connection port. The connection port communicates with the inside of the flow guiding cavity, and the flow guiding cavity is used to guide steam to the flow guiding hole.

[0008] According to the above technical solution, a guide groove is provided on the outer wall of the rotating drum. The guide groove is inclinedly opened at the gap of the guide blade to guide the steam. A guide pipe is fixedly connected to the outer wall of the spray chamber. The end of the guide pipe near the guide groove matches the opening position of the guide groove.

[0009] According to the above technical solution, the outer wall of the rotating drum is provided with an auxiliary heating mechanism, which includes a heat-conducting cylinder. The inner wall of the heat-conducting cylinder is rotatably connected to the outer wall of the rotating drum through a bearing. The outer wall of the heat-conducting cylinder is fixedly connected to the inner wall of the spray chamber. A heat-conducting groove is opened on the outer wall of the heat-conducting cylinder. The inside of the heat-conducting groove is connected to a guide pipe. A heating pipe is fixedly connected to the wall of the heat-conducting groove. A heating block is provided inside the heating pipe for auxiliary heating of steam. By using the auxiliary heating mechanism to auxiliary heat the steam, the temperature of the steam during the diffusion and sterilization process in the equipment is maintained, so that the temperature inside the equipment can rise rapidly to the sterilization temperature, thereby increasing the working efficiency of the can production sterilization equipment.

[0010] According to the above technical solution, an isolation block is fixedly connected to the wall of the heat conduction groove. The isolation block is set at the gap of the heating tube and is used to isolate the heat. A second guide groove is opened on the inner wall of the heat conduction cylinder. The second guide groove is connected to the inside of the heat conduction groove and is used to guide the heat of the heating tube. The position of the second guide groove corresponds to the nozzle.

[0011] According to the above technical solution, a motor is fixedly connected to the outer wall of the spray chamber, and a circulation mechanism is provided inside the spray chamber. The circulation mechanism includes a baffle, and a guide vane is fixedly connected to the inner wall of the baffle. The inner wall of the guide vane is fixedly connected to the output end of the motor. The guide vane is used to guide the steam and draw in the air located at the center of the spray chamber. The circulation mechanism draws in the steam around the cans in the central area, so that the steam in the outer area flows quickly to the central area and maintains the consistency of the steam temperature with the outer area. This reduces the difference in the actual effective sterilization time of the cans in the inner and outer areas and reduces the overall sterilization time of the can production sterilization equipment.

[0012] According to the above technical solution, the end of the guide pipe away from the guide groove is connected to the inside of the baffle, and the guide pipe is used to guide the steam. The end of the baffle away from the motor is connected to the inside of the spray chamber. The outer wall of the baffle is rotatably connected to the inner wall of the spray chamber through a bearing to guide the low-temperature steam extracted from the central area. It also works with the auxiliary heating mechanism to heat the low-temperature steam and return it to the internal and external disinfection areas of the equipment to mix with the steam in the original external disinfection area, so as to maintain the consistency of the disinfection steam temperature in the external area.

[0013] According to the above technical solution, a second guide vane is fixedly connected to the outer wall of the baffle. The second guide vane is used to guide the steam. A connecting groove is opened on the outer wall of the baffle. The connecting groove is connected to the inside of the baffle. The connecting groove is used to guide the steam to the inside of the baffle and guide the high-temperature steam outside the disinfection area to mix with the low-temperature steam at the center of the disinfection area. The low-temperature steam is heated to prevent the temperature of the extracted low-temperature steam from being too low, which would prevent the heating pipe from heating the steam in the center area to the set temperature and causing the overall spray steam temperature inside the spray chamber to decrease.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention uses a flow guiding mechanism to generate a swirling flow of steam, which can quickly flow through the gaps between cans to the can located in the central area, so that the steam in the central area can be heated rapidly and kept in the same temperature as the steam in the outer area. This reduces the difference in the actual effective sterilization time between the inner and outer areas of the can, and reduces the overall sterilization time of the can production sterilization equipment.

[0015] 2. The present invention uses a flow guiding mechanism to guide the sprayed steam to generate swirling flow, thereby maintaining a consistent steam temperature inside the equipment. This prevents the steam temperature from dropping during the spraying and diffusion process, which could lead to insufficient sterilization time for canned goods in the surrounding area, and increases the stability of the sterilization equipment for canned goods production.

[0016] 3. This invention uses an auxiliary heating mechanism to heat the steam, maintaining the temperature of the steam during the diffusion and sterilization process within the equipment, enabling the internal temperature of the equipment to rise rapidly to the sterilization temperature, thereby increasing the working efficiency of the sterilization equipment for canned food production.

[0017] 4. This invention uses a circulation mechanism to draw steam from the area surrounding the cans in the central region, allowing steam from the outer region to flow rapidly towards the central region and maintaining a consistent steam temperature with the outer region. This reduces the difference in the actual effective sterilization time between the inner and outer regions of the cans, and lowers the overall sterilization time of the can production sterilization equipment.

[0018] 5. The present invention guides the low-temperature steam extracted from the central area through a circulation mechanism, and in conjunction with an auxiliary heating mechanism, heats the low-temperature steam and returns it to the internal and external disinfection areas of the equipment to mix with the steam in the original external disinfection area, thereby maintaining the consistency of the disinfection steam temperature in the external area.

[0019] 6. The present invention guides the high-temperature steam outside the disinfection area through a circulation mechanism, so that the high-temperature steam mixes with the low-temperature steam extracted from the center of the disinfection area, and heats the low-temperature steam. This prevents the temperature of the extracted low-temperature steam from being too low, which would prevent the heating pipe from heating the steam in the center area to the set temperature, resulting in a decrease in the overall spray steam temperature inside the spray chamber.

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example 1, please refer to Figures 1-6 The present invention provides a technical solution: a sterilization device in the production process of fruit canning, including a spray chamber 100, a support channel 101 fixedly connected to the inner wall of the spray chamber 100, a motor 102 fixedly connected to the outer wall of the spray chamber 100, and a flow guiding mechanism 200 provided inside the spray chamber 100. During the steam spray sterilization process of fruit canned goods, the static stacking of cans leads to uneven heat distribution. Cans located in the central area of ​​the equipment are blocked by the outer cans, resulting in low heating efficiency in the central area. Cans in the peripheral area are directly exposed to the high-speed steam flow and are heated intensely, causing differences in the actual effective sterilization time and slowing down the overall sterilization time. Therefore, a flow guiding mechanism 200 is set up to guide the sprayed steam to generate swirling flow, so that the steam temperature inside the equipment remains consistent. This prevents the steam temperature from dropping during the spray diffusion process, which would lead to insufficient sterilization time for cans in the peripheral areas. This increases the stability of the sterilization equipment for canned goods. At the same time, the steam swirling flow can quickly flow through the gaps between the cans to the cans located in the central area, so that the steam in the central area heats up quickly and is consistent with the steam temperature in the outer area. This reduces the difference in the actual effective sterilization time between the inner and outer areas of the cans and shortens the overall sterilization time of the equipment. The flow guiding mechanism 200 includes a rotating drum 201. The outer wall of the rotating drum 201 is rotatably connected to the inner wall of the spray chamber 100 via bearings. The outer wall of the rotating drum 201 is driven by the output end of a motor 102 via a synchronous belt. A flow guiding hole 202 is provided on the outer wall of the rotating drum 201. A nozzle 204 is fixedly connected to the inner wall of the rotating drum 201 and communicates with the flow guiding hole 202. The nozzle 204 is used to guide steam to spray the canned goods. A flow guiding blade 205 is fixedly connected to the inner wall of the rotating drum 201. The flow guiding blade 205 is inclinedly arranged on the inner wall of the rotating drum 201 and is used for... To guide the steam flow, a guide cavity 106 is provided on the inner wall of the spray chamber 100, and a connection port 104 is fixedly connected to the outer wall of the spray chamber 100. The connection port 104 communicates with the interior of the guide cavity 106. The guide cavity 106 is used to guide the steam flow into the guide hole 202. A guide groove 203 is provided on the outer wall of the rotating drum 201. The guide groove 203 is inclinedly opened at the gap of the guide blade 205 for guiding the steam flow. A guide pipe 103 is fixedly connected to the outer wall of the spray chamber 100. The end of the guide pipe 103 near the guide groove 203 matches the opening position of the guide groove 203. When the sterilization device is put into use during the fruit canning process, the filled cans are placed in the loading cart, which is then sent into the spray chamber 100 via the support channel 101. The connection port 104 is connected to the steam delivery pipeline via a flange, injecting steam into the guide chamber 106. The guide chamber 106 guides the steam, allowing it to enter the guide hole 202 and then be sprayed out through the nozzle 204 to sterilize the cans. Simultaneously, the guide hole 202 is activated, causing the rotating drum 201 to rotate on the inner wall of the spray chamber 100, thus spraying the cans through the nozzle 204. During the process, the rotating drum 201 sprays the rotating cans, while the guide vanes 205 guide the steam inside the rotating drum 201. The guide vanes 205 are also inclined inside the rotating drum 201, causing the steam to swirl in the outer area of ​​the can, so that the steam temperature of the cans in the outer area is kept uniform and flows to the inner area of ​​the cans. At the same time, the speed of the steam flowing from the outer area of ​​the cans to the inner area of ​​the cans is increased, reducing the sterilization time difference between the outer and inner areas of the cans, thereby reducing the maintenance time of the steam spray sterilization equipment for cans.

[0024] Example 2, based on Example 1, please refer to... Figure 7 The present invention provides a technical solution: an auxiliary heating mechanism 300 is provided on the outer wall of the rotating cylinder 201; During the steam spray sterilization process of canned fruit, the static stacking of cans leads to uneven heat distribution. Cans located in the central area of ​​the equipment are blocked by the outer cans, resulting in low heating efficiency in the central area. Cans in the edge areas are directly exposed to the high-speed steam flow and are heated intensely, causing differences in the actual effective sterilization time of the cans and slowing down the overall sterilization time. Therefore, an auxiliary heating mechanism of 300 is set up to assist in heating the steam, maintain the temperature of the steam during the diffusion sterilization process in the equipment, enable the internal temperature of the equipment to rise rapidly to the sterilization temperature, and increase the working efficiency of the can production sterilization equipment. The auxiliary heating mechanism 300 includes a heat-conducting cylinder 301. The inner wall of the heat-conducting cylinder 301 is rotatably connected to the outer wall of the rotating cylinder 201 via a bearing. The outer wall of the heat-conducting cylinder 301 is fixedly connected to the inner wall of the spray chamber 100. A heat-conducting groove 302 is provided on the outer wall of the heat-conducting cylinder 301. The interior of the heat-conducting groove 302 is connected to the guide pipe 103. A heating pipe 303 is fixedly connected to the wall of the heat-conducting groove 302. A heating block is provided inside the heating pipe 303 for auxiliary heating of steam. An isolation block 304 is fixedly connected to the wall of the heat-conducting groove 302. The isolation block 304 is located at the gap of the heating pipe 303 and is used to isolate heat. A second guide groove 305 is provided on the inner wall of the heat-conducting cylinder 301. The second guide groove 305 is connected to the interior of the heat-conducting groove 302 and is used to guide the heat of the heating pipe 303. The position of the second guide groove 305 corresponds to the nozzle 204. During the rotation of the rotating drum 201, steam is sprayed onto the cans through the nozzle 204 for sterilization. As the steam diffuses inside the rotating drum 201, its temperature decreases. The heating tube 303 is activated to heat the heat-conducting cylinder 301, causing the heat to accumulate in the heat-conducting groove 302. Simultaneously, the heat is isolated by the isolation block 304, and the hot air is guided by the second guide groove 305. The hot air flows into the rotating drum 201 through the first guide groove 203 to assist in heating the steam, ensuring a consistent steam temperature inside the rotating drum 201. This prevents the steam temperature from decreasing during the spray sterilization process, which would reduce sterilization efficiency. Furthermore, as the hot air enters the rotating drum 201 through the second guide groove 305 to heat the steam, the first guide groove 203, which is inclined and located on the outer wall of the rotating drum 201, works in conjunction with the second guide groove 305 to turbulent the air, ensuring uniform heating of the steam during the auxiliary heating process.

[0025] Example 3, based on Examples 1 and 2, please refer to... Figure 8 The present invention provides a technical solution: a motor 105 is fixedly connected to the outer wall of the spray chamber 100, and a circulation mechanism 400 is provided inside the spray chamber 100; During the steam spray sterilization process for fruit cans, the static stacking of cans leads to uneven heat distribution. Cans located in the central area of ​​the equipment are obstructed by the surrounding cans, resulting in low heating efficiency in the central area. Cans in the peripheral areas are directly exposed to the high-speed steam flow and are heated intensely, causing differences in the actual effective sterilization time and slowing down the overall sterilization process. Therefore, a circulation mechanism 400 is installed to extract steam from around the cans in the central area, allowing steam from the outer area to flow rapidly to the central area and maintaining a consistent steam temperature with the outer area. This reduces the difference in the actual effective sterilization time between the inner and outer areas of the cans, thus reducing the sterilization time reduction in can production. The equipment maintains the overall sterilization time of canned goods while simultaneously guiding the low-temperature steam extracted from the central area. In conjunction with the auxiliary heating mechanism 300, the low-temperature steam is heated and returned to the internal and external sterilization areas of the equipment to mix with the steam in the original external sterilization area, maintaining the consistency of the sterilization steam temperature in the external area. At the same time, the high-temperature steam outside the sterilization area is guided to mix with the low-temperature steam extracted from the center of the sterilization area, heating the low-temperature steam to prevent the extracted low-temperature steam temperature from being too low, which would prevent the heating pipe 303 from heating the steam in the central area to the set temperature, resulting in a decrease in the overall spray steam temperature inside the spray chamber 100. The circulation mechanism 400 includes a baffle 401. A guide vane 403 is fixedly connected to the inner wall of the baffle 401. The inner wall of the guide vane 403 is fixedly connected to the output end of the motor 105. The guide vane 403 is used to guide the steam and draw in the air located at the center of the spray chamber 100. The end of the guide pipe 103 away from the guide groove 203 is connected to the inside of the baffle 401. The guide pipe 103 is used to guide the steam. The end of the baffle 401 away from the motor 105 is connected to the inside of the spray chamber 100. The outer wall of the baffle 401 is rotatably connected to the inner wall of the spray chamber 100 through a bearing. A guide vane 402 is fixedly connected to the outer wall of the baffle 401. The guide vane 402 is used to guide the steam. A connecting groove 404 is opened on the outer wall of the baffle 401. The connecting groove 404 is connected to the inside of the baffle 401 and is used to guide the steam to the inside of the baffle 401. Steam enters the rotating drum 201 through nozzle 204 to sterilize the cans. During sterilization, motor 105 drives the guide vanes 403 to rotate, drawing air from the area surrounding the cans in the central region. This air enters the connection port 104 and is then guided by the guide pipe 103. The cold air surrounding the cans in the central region is then sent to the heat transfer groove 302, where it is heated by the heating pipe 303. After being heated, the air flows back into the rotating drum 201 through the guide groove 305 to mix with the steam surrounding the cans in the outer region. This ensures that the steam temperature in the central region is consistent with that in the outer region. The guide vanes 403 continuously circulate and draw in the steam from the area surrounding the cans in the central region, thus sterilizing the cans. The steam temperature of the cans in the central area rises rapidly, reducing the time difference between sterilization of the cans in the outer area and the cans in the central area. At the same time, the guide vane 3 403 drives the baffle 401 to rotate inside the spray chamber 100 during rotation, so that the steam in the outer area of ​​the guide vane 2 402 is guided and enters the baffle 401 through the connecting groove 404. It mixes with the steam drawn into the guide baffle 401 by the guide vane 3 403, which assists in heating the steam in the central area drawn into the baffle 401. This prevents the steam temperature in the central area from being too low, which would prevent the heating tube 303 from heating the steam in the central area to the set temperature, resulting in a decrease in the overall spray steam temperature inside the spray chamber 100.
