Description

Technical Field

[0001] This invention relates to the field of sterilization and preservation technology, specifically to a sterilization equipment and process for fruit juice production. Background Technology

[0002] In the juice production process, sterilization is a core step in ensuring product safety and extending shelf life. While traditional water bath sterilization equipment is widely used, it still suffers from drawbacks such as low heat transfer efficiency, poor temperature uniformity, and high levels of manual intervention. Current technologies primarily rely on static immersion or simple conveyor belt heating for sterilizing bagged juice, resulting in insufficient heat transfer efficiency, uneven temperature distribution, and low automation.

[0003] Therefore, there is an urgent need for an innovative sterilization device that integrates dynamic heat transfer, intelligent control and automated processing to balance efficiency, safety and economy.

[0004] Patent CN202210959643.3 discloses a high-temperature and high-pressure conditioning sterilization device for double-layer water bath spraying. The device includes a sterilization vessel with a first input port and a second input port. A first water inlet valve is installed on the first input port, and an exhaust valve is installed on the second input port. A first heater is installed inside the sterilization vessel, and a steam generating chamber is mounted on the top of the sterilization vessel via a support rod. A second heater is installed inside the steam generating chamber, and a second water inlet valve is installed at the input end of the steam generating chamber. The steam generating chamber has an output port, which is connected to the exhaust valve via a connecting pipe. By opening the first and second water inlet valves, water is discharged into the sterilization vessel and the steam generating chamber, respectively. At this time, the first and second heaters are activated, and the exhaust valve is opened, allowing steam generated in the steam generating chamber to enter the sterilization vessel through the connecting pipe. The combined use of hot water and steam improves the sterilization effect on materials. However, this patent also suffers from the problem of time-consuming and labor-intensive loading and unloading.

[0010] According to the above technical solution, a boundary layer breaking device is provided at the boundary of the sector space. The boundary layer breaking device includes a partition shaft and a compression sleeve. Multiple support sliders are slidably connected to the outside of the partition shaft. A spring is provided between the support sliders. Pushing plates are provided on both sides of the pushing plate near the sector space.

[0013] According to the above technical solution, the discharge end of the water tank is provided with a discharge support column, and a collection bucket is provided on the outside of the rotary drain pipe.

[0014] According to the above technical solution, transmission belt assemblies are provided on both sides of the rotary drain pipe, and the strip-shaped liquid outlet is tangentially arranged with the outer surface of the rotary drain pipe.

[0015] A sterilization process for fruit juice production, the sterilization process of the fruit juice production sterilization equipment includes the following steps: S1: The bagged juice is conveyed to the loading basket via a conveyor belt, and the loading basket is hoisted and placed on the rotary drain pipe in the water tank by the cooperation of hydraulic push rod and transfer frame; S2: Pour the heated water from the step-down cooling water tank into the step-heating water tank; S3: By controlling the operation of the transmission belt assembly, and under the action of gear two and the transfer frame, the loading basket is driven to rotate; S4: The bagged juice is rapidly heated by high-temperature water spray from the rotating drain pipe and the rotation of the loading basket. S5: Gradually heat up, sterilize, and cool down the shipping crates; S6: The loading basket is placed on the unloading support column by the hydraulic push rod and the transfer frame, so as to realize the sterilization and automatic unloading of bagged juice.

[0016] This invention provides a sterilization device and sterilization process for fruit juice production. It has the following beneficial effects: This invention involves a compression bushing that contacts a rotary compression table at the bottom of an insulated sliding cover. Guided by the rotary compression table, the compression bushing moves downward and compresses the support slider. Since each support slider on the push plate is hinged to each hinged platform on the push plate via a support swing rod, the angle between the support swing rods decreases as the support slider moves downward, causing the two push plates to move away from each other and compress the bagged juice in the fan-shaped space. This applies periodic pressure to the bagged juice, forcing it to flow inside the bag, breaking the thermal boundary layer, and allowing the center temperature to reach the sterilization target more quickly. This invention significantly optimizes sterilization efficiency and product quality by using a hollow frame with a perforated structure in the middle of the shipping basket and simultaneously injecting water into the middle area during heating. The perforated structure allows hot water to directly contact the middle area of ​​the packaging bag, breaking the limitation of traditional water bath sterilization that relies solely on heat transfer from the bag surface, shortening the heat transfer path, and improving the heat transfer efficiency of bagged juice. This invention involves hoisting a shipping basket and aligning a rope-driven plate with a rotary drain pipe. As the shipping basket descends until the rope-driven plate contacts the collection bucket, it moves upward. At this point, the slide, pulled by the guide rope, rotates the limit lock plate until it aligns with the slide. Under gravity, the bagged juice pushes open the bottom support plate, causing it to bend along the hinge plate until the bagged juice is discharged from the bottom support plate to the outside of the shipping basket. This method, with its gentle discharge from the bottom, avoids seal cracking or surface scratches caused by collisions, friction, or gripping during the transfer process, significantly reducing the bag breakage rate. It also facilitates automated continuous unloading of bagged juice, making it particularly suitable for mass production. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Please see Figure 1-13 A fruit juice production sterilization device includes a water tank 1, a hydraulic push rod 3, a loading basket 2 for holding bagged fruit juice, a hydraulic push rod 3 for lifting and transporting the loading basket 2, a transfer frame 4 for guiding the loading basket 2, and a guide rail frame 6 for mounting the hydraulic push rod 3 and the transfer frame 4. The number of water tanks 1 is multiple, and the multiple water tanks 1 are used for stepped heating, pasteurization, and stepped cooling. Each pool of water tank 1 is provided with at least one rotary drain pipe 11 distributed at equal intervals, and the rotary drain pipe 11 is rotatably connected to the water tank 1. The shipping basket 2 includes a cylindrical frame 201 and a hollow frame 202. The hollow frame 202 is located in the middle of the cylindrical frame 201, and the two are connected by multiple partition rods 203. The middle of the hollow frame 202 is hollow. The shipping basket 2 is placed in the water tank 1, and the rotary drain pipe 11 is located inside the hollow frame 202.

[0021] The rotary drain pipe 11 in the stepped heating water tank 1 is connected to the water flow in the stepped cooling water tank 1 through a high-pressure pump.

[0022] Furthermore, the stepped heating includes a 50-degree Celsius heating pool and a 70-degree Celsius heating pool; Pasteurization uses a single 90-degree Celsius constant temperature bath, which can be flexibly adjusted according to the specific sterilization product. The stepped cooling system includes a 70-degree Celsius cooling pool, a 50-degree Celsius cooling pool, and a 30-degree Celsius cooling pool.

[0023] Furthermore, the water tank 1 can be equipped with multiple rotary drain pipes 11 for placing the transport baskets 2. Since the transport baskets 2 in each of the stepped heating, pasteurization and stepped cooling chambers in the water tank 1 need to be continuously placed for a period of time, the multiple transport baskets 2 can ensure the continuous operation of the device.

[0024] Furthermore, the hydraulic push rod 3 is used to control the up and down movement of the loading basket 2 and its axial movement along the hydraulic push rod 3.

[0025] Furthermore, during the heating phase of the bagged juice, the bagged juice placed in the heating tank will cause the heat in the heating tank to decrease, requiring continuous heating to maintain a constant temperature in the heating tank. During the cooling phase after the bagged juice has been sterilized, the bagged juice placed in the cooling tank will cause the heat in the cooling tank to increase, requiring continuous input of cold water to maintain a constant temperature in the cooling tank. Therefore, by introducing the heated water from the 70-degree Celsius cooling pool into the 70-degree Celsius heating pool, and having the water flow from the inside to the outside of the hollow frame 202, the temperature difference between the bagged juice and the water in the heating pool is increased, thereby improving the heating effect on the bagged juice. The same applies to the 50-degree Celsius cooling pool. Compared to traditional electric heating, this temperature difference in water flow can reduce the impact of higher water temperatures in a single area on the bagged juice.

[0026] A transmission belt assembly 12 is provided on one side of the guide rail frame 6. The adapter frame 4 is slidably connected to the guide rail frame 6. The adapter frame 4 consists of a guide part and a locking part. The locking part of the adapter frame 4 is located at the bottom of the adapter frame 4 and is locked to the top of the loading basket 2. The guide part of the adapter frame 4 is located at the top of the adapter frame 4. A gear 2 13 is connected to the guide part near the transmission belt assembly 12. The gear 2 13 is connected to the transmission belt assembly 12. The bottom of the guide section of the adapter frame 4 is slidably connected to a synchronous rotating shaft 14, which is connected to the top of the loading basket 2. A synchronization block 5 is provided on the adjacent side of the hydraulic push rod 3 and the adapter frame 4. The synchronization block 5 consists of a locking platform and a locking slot. The operation of the hydraulic push rod 3 can control the locking platform and the locking slot on the synchronization block 5 to engage.

[0027] Furthermore, the transmission belt of the transmission belt assembly 12 is a toothed belt, and the toothed belt of the transmission belt assembly 12 meshes with the gear 13.

[0028] Furthermore, keyways or keyways are provided on both the inner and outer walls of the synchronous shaft 14, and the synchronous shaft 14 is connected to the adapter frame 4 and the loading basket 2 through the keyways or keyways.

[0029] Furthermore, the slot fixed to the adapter 4 is wedge-shaped, and the platform fixed to the hydraulic push rod 3 is also wedge-shaped. The wedge-shaped inclined surface guides the system, and the weight of the loading basket 2 ensures the secure engagement of the slot and the platform.

[0030] Furthermore, the second gear 13 can be slidably connected to the outside of the adapter frame 4, and a limiting retaining ring can be used to maintain the gear 13 and the toothed belt of the transmission belt assembly 12 in a state of transmission engagement.

[0031] Furthermore, the shipping basket 2 and the adapter frame 4 are engaged by the cooperation of the boss and the groove. After they are engaged, the shipping basket 2 can still rotate relative to the adapter frame 4.

[0032] In use, the hydraulic push rod 3 controls the movement of the shipping basket 2 up and down and along the arrangement direction of the water tank 1 until the shipping basket 2 is placed in the water tank 1 corresponding to the rotary drain pipe 11. When the shipping basket 2 is placed on the adapter frame 4, the synchronous rotating shaft 14 is first lifted and stored in the guide part of the adapter frame 4, then the locking part of the adapter frame 4 is locked with the top of the shipping basket 2, and then the synchronous rotating shaft 14 is aligned and locked with the top of the shipping basket 2. This allows the transmission belt assembly 12 to continuously drive the shipping basket 2 to rotate, thereby improving the heating efficiency of the bagged juice in the shipping basket 2. At the same time, it can also interfere with the flow of water in the water tank 1 to ensure the uniformity of water temperature in the water tank 1.

[0033] The outer side of the cylindrical frame 201 is covered with a water-permeable sleeve 204, and the hollow frame 202 is filled with a water-guiding side plate 205. Multiple water-guiding louvers 206 are bent on the water-guiding side plate 205, and the water-guiding louvers 206 are bent toward the middle of the hollow frame 202. The top of the hollow frame 202 is fixedly connected to a guide cone 208, and the middle of the guide cone 208 is fixedly connected to a transition shaft 209. The bottom of the cylindrical frame 201 and the hollow frame 202 is provided with a material support plate 207, which is used to support the bagged juice. The dividing rod 203 divides the space composed of the cylindrical frame 201 and the hollow frame 202 into multiple sector-shaped spaces.

[0034] Furthermore, by aligning the conveyor belt with the top of the loading basket 2, by blocking and limiting the bagged juice with the permeable sleeve 204, and by guiding the bagged juice with the guide cone 208, the bagged juice is stacked in the fan-shaped space by its own weight. It can be used in conjunction with the turntable to drive the loading basket 2 to rotate as a whole, so that the bagged juice is evenly placed in the space composed of the cylindrical frame 201 and the hollow frame 202.

[0035] Furthermore, the adapter shaft 209 is used for transmission engagement with the synchronous shaft 14.

[0036] A boundary layer breaking device 8 is provided at the junction of the fan-shaped space. The boundary layer breaking device 8 includes a partition shaft 803 and a compression sleeve 802. Multiple support sliders 807 are slidably connected to the outside of the partition shaft 803. A spring 804 is provided between the support sliders 807. Push plates 801 are provided on both sides of the push plate 801 near the fan-shaped space. Multiple hinge platforms 806 are slidably connected to some of the push plates 801. The support sliders 807 and the hinge platforms 806 are hinged by a support swing rod 805. The extrusion sleeve 802 is fitted onto the top of the push plate 801, and the bottom of the extrusion sleeve 802 contacts the top of the support slider 807 located on the top of the push plate 801. The push plate 801 is widened on the side closest to the bagged juice and has raised dots on its surface.

[0037] Furthermore, the push plate 801 can separate the bagged juice in the adjacent fan-shaped space, avoiding the problem of reduced thermal conductivity caused by disorderly stacking of bagged juice, and also facilitating the rapid discharge of bagged juice from the shipping basket 2.

[0038] The top of the water tank 1 is synchronously slidably connected to an insulated sliding cover 7, and the bottom side of the insulated sliding cover 7 is fixedly connected to a rotary extrusion table 10, which corresponds to the position of the extrusion bushing 802. The insulated sliding cover 7 is used to keep the water temperature in the water tank 1 warm.

[0039] Furthermore, the transmission belt assembly 12 drives the gear 13 to rotate, which in turn drives the loading basket 2 to rotate. When the extrusion sleeve 802 on the loading basket 2 contacts the rotary extrusion table 10 at the bottom of the heat preservation sliding cover 7, the extrusion sleeve 802 moves down under the guidance of the rotary extrusion table 10 and extrudes the support slider 807. Since each support slider 807 on the push plate 801 and each hinge table 806 on the push plate 801 are hinged through the support swing rod 805, when the support slider 807 moves down, the included angle between the support swing rods 805 decreases, and the two push plates 801 move away from each other, and extrudes the bagged juice in the fan-shaped space to break the liquid layer of the bagged juice, thereby achieving rapid heating of the juice in the middle of the bagged juice.

[0040] The bottom side of the loading basket 2 has an automatic unloading loader 9. The automatic unloading loader 9 includes a hinge plate 901 and a rope drag plate 902. The material support bottom plate 207 is hinged to the bottom frame of the hollow frame 202 through the hinge plate 901, and a torsion spring for resetting is provided at the hinge. A slide table 907 is slidably connected to the outside of the divider 203 located on the bottom side of the loading basket 2. A limit locking plate 904 is rotatably connected to the bottom of the divider 203. The limit locking plate 904 is used to support the edge of the material support base plate 207. A gear 905 is fixedly connected to the bottom of the limit locking plate 904. A rack 906 is fixedly connected to the slide table 907, and the rack 906 meshes with the gear 905. A second spring 908 is sleeved on the outside of the separator rod 203. The second spring 908 supports the slide table 907 under normal conditions and maintains the limit locking plate 904 to support the edge of the material support base plate 207. A force-guiding rope 903 is fixedly connected to one side of the slide table 907, and a rope drag plate 902 is slidably connected to the bottom side of the guide cone 208. The other end of the force-guiding rope 903 is fixedly connected to the rope drag plate 902.

[0041] Furthermore, the 903 force-guiding rope is normally in a taut state.

[0042] In use, by pulling the slide table 907, the rack 906 on the slide table 907 drives the gear 905 to rotate, and the limit locking plate 904 rotates to coincide with the slide table 907. At this time, the material support plate 207 is no longer limited by the limit locking plate 904. Under the action of gravity, the bagged juice pushes open the material support plate 207, causing the material support plate 207 to bend along the hinge plate 901 until the bagged juice is discharged from the material support plate 207 to the outside of the loading basket 2.

[0043] The discharge end of water tank 1 is equipped with a discharge support column 15, and a collection bucket 16 is provided on the outside of the rotary drain pipe 11.

[0044] In use, the loading basket 2 is hoisted and the rope drag plate 902 is aligned with the rotary drain pipe 11. When the loading basket 2 moves down until the rope drag plate 902 contacts the collection bucket 16, the rope drag plate 902 moves up. At this time, the slide table 907, under the traction of the guide rope 903, drives the limit lock plate 904 to rotate until the limit lock plate 904 coincides with the slide table 907. At this time, the bagged juice pushes open the material support plate 207 under the action of gravity, so that the material support plate 207 bends along the hinge plate 901 until the bagged juice is discharged from the material support plate 207 to the outside of the loading basket 2.

[0045] The rotary drain pipe 11 has strip-shaped liquid outlets 17 on both sides, and the strip-shaped liquid outlets 17 are tangentially arranged with the outer surface of the rotary drain pipe 11.

[0046] A sterilization process for fruit juice production, the sterilization process of the fruit juice production sterilization equipment includes the following steps: S1: The bagged juice is conveyed to the loading basket 2 by the conveyor belt, and the loading basket 2 is hoisted and placed on the rotary drain pipe 11 in the water tank 1 by the cooperation of the hydraulic push rod 3 and the transfer frame 4. S2: The heated water in the stepped cooling water tank 1 is poured into the stepped heating water tank 1; S3: By controlling the operation of the transmission belt group 12, and under the action of gear 13 and the adapter frame 4, the loading basket 2 is driven to rotate; S4: The bagged juice is rapidly heated by the high-temperature water spray from the rotary drain pipe 11 and the rotation of the loading basket 2. S5: Gradually heat up, sterilize, and cool down the loading crate 2; S6: The loading basket 2 is placed on the unloading support column 15 by controlling the hydraulic push rod 3 and the transfer frame 4 to achieve sterilization and automatic unloading of bagged juice.

[0047] Working principle: Bagged juice is conveyed to the loading basket 2 via a conveyor belt. The loading basket 2 is then hoisted and placed on the rotary drain pipe 11 inside the water tank 1 by the cooperation of the hydraulic push rod 3 and the transfer frame 4. The transmission belt group 12 is controlled to work, and the loading basket 2 is driven to rotate under the action of the gear 13 and the transfer frame 4. The bagged juice is rapidly heated or cooled by the high-temperature water spray from the rotary drain pipe 11 and the rotation of the loading basket 2. The loading basket 2 is gradually heated, sterilized and cooled. After the loading basket 2 is processed, the loading basket 2 is placed on the unloading support column 15 by the control of the hydraulic push rod 3 and the transfer frame 4, so as to realize the sterilization and automatic unloading of the bagged juice.
