Description

Technical Field

[0001] The invention relates to the technical field of beverage processing, in particular to a rapid sterilization method and a sterilization device for beverage processing. Background Art

[0002] When processing beverages, the process involved includes raw material processing, mixing, filling, sterilization and packaging. At present, sterilization autoclaves are generally used to sterilize beverages after filling to ensure the safety and hygiene of the products.

[0003] A sterilizer is a device that sterilizes items through high pressure and high temperature. It usually uses a water spray sterilization method. The nozzles on both sides and the top of the sterilizer spray mist-like hot water onto the surface of the beverage can to sterilize the beverage in the can. The temperature is uniform without dead corners, and the heating and cooling are rapid.

[0004] In the prior art, the poured beverage is generally placed in a sterilization basket, and then multiple sterilization baskets are stacked on a transfer vehicle, and finally the transfer vehicle is pushed into the sterilization kettle for sterilization. Then, during use, it was found that the stacked sterilization baskets would form a certain shielding in the upper and lower directions, that is, the upper sterilization frame would shield the lower sterilization frame, so that the lower sterilization frame could not fully receive the hot water spray, which is not conducive to the full contact between the hot water and the beverage can, resulting in low sterilization efficiency.

DETAILED DESCRIPTION

[0055] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0056] Example 1: Please refer to Figures 1 to 13 , a rapid sterilization device for beverage processing, comprising a sterilization kettle 1 and a transfer vehicle 2 placed in the sterilization kettle 1; the sterilization kettle 1 injects water into a spray pipe through a high-efficiency circulation pump, a filter and a high-efficiency heat exchanger, and then sprays hot water in an atomized state onto the surface of the beverage can through a spray nozzle, forming a water film from top to bottom to transfer heat, thereby sterilizing the beverage in the beverage can. This is a prior art and will not be repeated here.

[0057] This embodiment further includes: two fixed plates 3 , a main rotating shaft 4 , two rotating rings 6 , a plurality of supporting plates 8 and a plurality of unfolding and retracting mechanisms 10 .

[0058] Among them, two fixed plates 3 are fixed on the top of the transfer vehicle 2 at intervals along the axial direction of the sterilizer 1, and a plurality of weight-reducing holes are opened on each fixed plate 3 to reduce the weight; at the same time, the existence of the weight-reducing holes makes it difficult for the fixed plates 3 to completely block the water mist.

[0059] Secondly, the main rotating shaft 4 is connected between the two fixed disks 3 through the cooperation and rotation of the bearing and the shaft seat. A power source 5 for driving the main rotating shaft 4 to rotate is installed on one of the fixed disks 3. In this embodiment, the power source 5 adopts a reduction motor, which drives the main rotating shaft 4 to rotate slowly counterclockwise. This is the prior art and will not be repeated here.

[0060] In addition, two rotating rings 6 are fixed on the main rotating shaft 4 at intervals along the axial direction of the main rotating shaft 4, and a plurality of hollow rotating shafts 7 are rotatably connected to each rotating ring 6 at equal intervals along the circumferential direction, and each hollow rotating shaft 7 is parallel to the main rotating shaft 4. Each support plate 8 is fixedly mounted between two opposite hollow rotating shafts 7, and a plurality of beverage placement components 9 are arranged on the top of each support plate 8 along the radial direction of the hollow rotating shaft 7 for placing beverage cans filled with beverages and sealed. Since the hollow rotating shaft 7 is rotatably connected to the rotating ring 6, the support plate 8 can always be in a horizontal state under the action of gravity.

[0061] With the above structure, when the power source 5 is working and drives the main rotating shaft 4 to rotate slowly counterclockwise, it can drive the two rotating rings 6 to rotate slowly counterclockwise synchronously, and then drive the pallet 8 which always remains in a horizontal state to rotate slowly counterclockwise; when the pallet 8 rotates to a certain height and there is no other pallet 8 blocking it above, the beverage cans on the pallet 8 can be fully in contact with the hot water, so that the beverages can be quickly sterilized, which solves the problem in the prior art that the sterilization baskets stacked together will form a certain obstruction in the upper and lower directions.

[0062] The following is a detailed description of the unfolding and retracting mechanism 10:

[0063] Each unfolding and retracting mechanism 10 is respectively arranged on each support plate 8, and is used to make each beverage placement component 9 on the support plate 8 unfold or retract mutually. Specifically, the interior of the support plate 8 is provided with an installation cavity 11 for installing other components; the unfolding and retracting mechanism 10 includes two movable plates 1001 slidably connected to the installation cavity 11, and a driving component 1002 is arranged on the support plate 8 for making the two movable plates 1001 move away from or approach each other. The side of the two movable plates 1001 moving away from each other extends to the outside of the installation cavity 11, and a side plate 1003 is fixed on the side of the two movable plates 1001 moving away from each other. In this embodiment, a plurality of support rods 1006 are fixed on the side of the two side plates 1003 moving toward each other, and a perforation 14 corresponding to each support rod 1006 is opened on each beverage placement component 9; when each beverage placement component 9 is in a mutually unfolded state, each beverage placement component 9 can be supported by the support rod 1006.

[0064] The innermost beverage placement assembly 9 is fixed to the middle of the support plate 8, and the position of the beverage placement assembly 9 remains unchanged. The two outermost beverage placement assemblies 9 are respectively fixed to the tops of the two movable plates 1001, and can move with the movable plates 1001. A variable distance connection member is connected between two adjacent beverage placement assemblies 9, and the variable distance connection member includes a plurality of slide grooves 1004 fixed to one of the beverage placement assemblies 9, and a slide rod 1005 that slides in each slide groove 1004 is fixed to the other beverage placement assembly 9.

[0065] With the above structure, when the driving assembly 1002 drives the two movable plates 1001 away from each other, it can drive the two outermost beverage placement assemblies 9 away from each other, and then drive the slide bar 1005 to slide in the slide groove 1004 until the limit position, thereby driving the adjacent beverage placement assemblies 9 to move outward, and repeating this process until each beverage placement assembly 9 is fully unfolded. After unfolding, hot water can flow between two adjacent beverage placement assemblies 9, so that the beverage can can be fully in contact with the hot water, and the sterilization effect is better.

[0066] When the driving component 1002 drives the two movable plates 1001 to approach each other, it can drive the two outermost beverage placement components 9 to approach each other, and then drive the sliding rod 1005 to slide in the slide groove 1004 until it reaches the limit position, and then push the adjacent beverage placement components 9 to continue to move inward. This is repeated until each beverage placement component 9 is completely retracted to reduce the space occupied by the lateral position, so as to better adapt to the radial accommodation space in the sterilizing kettle 1.

[0067] In this embodiment, the driving assembly 1002 includes a fixed shell 10021 fixed to the bottom of the support plate 8 and connected to the installation cavity 11, which is used to install other components. Two worms 10022 are rotatably connected in the fixed shell 10021 through the cooperation of bearings and shaft seats. The two worms 10022 are arranged at intervals along the axial direction of the hollow rotating shaft 7. The ends of the two worms 10022 that are away from each other extend outside the fixed shell 10021, which is convenient for connecting with other power output structures to drive the worms 10022 to rotate. A worm wheel 10023 meshing with each worm 10022 is arranged in the installation cavity 11, and a bidirectional threaded rod 10024 perpendicular to the worm 10022 is fixed in the middle of each worm wheel 10023. Each bidirectional threaded rod 10024 is connected to the installation cavity 11 through the cooperation of a bearing and a shaft seat, and a thread groove 10025 spirally matched with both ends of the bidirectional threaded rod 10024 is respectively provided on the two movable plates 1001. When the worm 10022 rotates, the cooperation between the worm 10022 and the worm wheel 10023 can drive the bidirectional threaded rod 10024 to rotate, so that the two movable plates 1001 are driven to move away from or approach each other through the spiral cooperation between the bidirectional threaded rod 10024 and the thread groove 10025.

[0068] It is worth mentioning that the driving assembly 1002 further includes a first pulley 10026 fixed to the outer end of each worm 10022, and a connecting shaft 10027 is rotatably connected in the hollow rotating shaft 7 adjacent to each first pulley 10026, and both ends of each connecting shaft 10027 extend outside the hollow rotating shaft 7. A second pulley 10028 connected to the adjacent first pulley 10026 is fixed at one end of the two connecting shafts 10027 close to each other, and a gear 10029 is fixed at one end of the two connecting shafts 10027 away from each other; when the connecting shaft 10027 rotates, the worm 10022 can be driven to rotate through the cooperation of the first pulley 10026 and the second pulley 10028.

[0069] An arcuate inner rack 12 and an arcuate outer rack 13 are fixed to the proximal end of the upper end of the inner surface of each fixed plate 3; when the main rotating shaft 4 rotates counterclockwise, when the gear 10029 is meshed with the arcuate outer rack 13, it can drive the connecting shaft 10027 to rotate, thereby driving the worm 10022 to rotate, and then driving the two movable plates 1001 to move away from each other, so that the beverage placement components 9 on the support plate 8 can be spread out. When the gear 10029 is meshed with the arcuate inner rack 12, it can drive the connecting shaft 10027 to rotate, thereby driving the two movable plates 1001 to move closer to each other, and then driving the beverage placement components 9 on the support plate 8 to retract. With this structure, the rotation of the rotating ring 6 is used as the power for the beverage placement components 9 on the support plate 8 to expand or retract each other, and no additional power components are required, which is more energy-saving.

[0070] It should be added that a certain distance is left between the arcuate inner rack 12 and the arcuate outer rack 13 so that each beverage placement assembly 9 on the support plate 8 can continue to rotate a certain distance when in a fully expanded state, thereby ensuring that the beverage cans can be fully in contact with hot water to ensure the sterilization effect.

[0071] The beverage placement component 9 is described in detail below:

[0072] The beverage placement assembly 9 includes a base 901 disposed on the top of the support plate 8. In this embodiment, the perforation 14 is provided on the base 901. Two support seats 902 are fixed at intervals along the axial direction of the hollow rotating shaft 7 on the top of the base 901. A flip shaft 903 is connected to the two support seats 902 by a bearing and a shaft seat. A plurality of beverage can placement net cylinders 904 are fixed at equal intervals along the axial direction on the flip shaft 903. The upper end of the beverage placement net cylinder 904 is open for taking and placing beverage cans. A plurality of mesh holes are evenly distributed on the side wall and the bottom wall of the beverage placement net cylinder 904 to ensure that the beverage can can normally contact with hot water. In this embodiment, the flip shaft 903 adopts a multi-stage structure, so that it can be fixed with a plurality of beverage can placement net cylinders 904, and then when the flip shaft 903 rotates, it can drive each beverage can placement net cylinder 904 on the same axis to flip synchronously.

[0073] In this embodiment, pull ropes 905 are fixed at both ends of the flip shaft 903, and an iron block 906 is fixed at the free end of each pull rope 905. A first electromagnet 907 and a second electromagnet 908 are respectively arranged on the left and right sides of each iron block 906, and each first electromagnet 907 and each second electromagnet 908 are fixed to the top of the base 901. When the first electromagnet 907 is energized, it can drive the iron block 906 to move to the left; when the second electromagnet 908 is energized, it can drive the iron block 906 to move to the right.

[0074] It should be added that a guide block 909 is fixed to the lower end of the iron block 906, and a guide rod 9010 that movably passes through the guide block 909 is fixed to the base 901. When the iron block 906 moves left and right under the action of the electromagnet, it can drive the guide block 909 to slide left and right on the guide rod 9010. Springs 9011 located on both sides of the guide block 909 are sleeved on the guide rod 9010 to apply an elastic force between the first electromagnet 907 and the second electromagnet 908 to the guide block 909. Under normal conditions, the elastic force applied by the spring 9011 causes the iron block 906 to be located between the first electromagnet 907 and the second electromagnet 908, so that the beverage can placement net cylinder 904 is in a vertical state by pulling the pull rope 905.

[0075] With the above structure, when the first electromagnet 907 and the second electromagnet 908 are in a power-off state, the iron block 906 is located between the first electromagnet 907 and the second electromagnet 908 through the elastic force applied by the spring 9011, so that the beverage can placing net tube 904 is in a vertical state by pulling the pull rope 905, and hot water can be sprayed onto the surface of the beverage can in the vertical state.

[0076] When the first electromagnet 907 is energized, the iron block 906 is driven to move toward the first electromagnet 907, thereby pulling the flip shaft 903 through the pull rope 905, and then driving the beverage can to place the net tube 904 to tilt to the right, and hot water can be sprayed onto the surface of the beverage can in a state of tilting to the right. When the second electromagnet 908 is energized, the iron block 906 is driven to move toward the second electromagnet 908, thereby pulling the flip shaft 903 through the pull rope 905, and then driving the beverage can to place the net tube 904 to tilt to the left, and hot water can be sprayed onto the surface of the beverage can in a state of tilting to the left. The state of the beverage can keeps changing, so that it can be in contact with hot water more comprehensively, and it is not easy to have a dead angle, the sterilization effect is effectively guaranteed, and the sterilization efficiency is greatly improved.

[0077] It is worth mentioning that an outer frame 15 corresponding to each support plate 8 is fixed on the outer ring of each rotating ring 6, and an external conductive head 16 is fixed on each outer frame 15, and each external conductive head 16 is electrically connected to each first electromagnet 907 on the corresponding support plate 8; it should be supplemented that the external conductive heads 16 on the two rotating rings 6 are opposite to each other, and the two opposite external conductive heads 16 are electrically connected to the two leads of the first electromagnet 907 respectively.

[0078] An inner frame 17 corresponding to each support plate 8 is fixed on the inner ring of each rotating ring 6, and an inner conductive head 18 is fixed on each inner frame 17. Each inner conductive head 18 is electrically connected to each second electromagnet 908 on the corresponding support plate 8; it should be supplemented that the inner conductive heads 18 on the two rotating rings 6 are opposite to each other, and the two opposite inner conductive heads 18 are electrically connected to the two leads of the second electromagnet 908 respectively.

[0079] A plurality of outer conductive sheets 19 and a plurality of inner conductive sheets 20 are fixed along the circumferential direction on the upper end of the inner surface of each fixed disk 3. The outer conductive sheets 19 and the inner conductive sheets 20 are staggered and distributed with each other. The outer conductive sheets 19 and the inner conductive sheets 20 are electrically connected to the external power supply. It should be added that the outer conductive sheets 19 on the two fixed disks 3 are opposite to each other, and the two opposite outer conductive sheets 19 are electrically connected to the positive and negative poles of the external power supply. The inner conductive sheets 20 on the two fixed disks 3 are opposite to each other, and the two opposite inner conductive sheets 20 are electrically connected to the positive and negative poles of the external power supply.

[0080] When the two rotating rings 6 rotate synchronously, since the outer conductive sheets 19 and the inner conductive sheets 20 are staggered, when the two opposite outer conductive heads 16 contact the corresponding outer conductive sheets 19, the first electromagnets 907 on the corresponding support plate 8 are in a powered-on state; at this time, the two inner conductive heads 18 corresponding to the support plate 8 do not contact the corresponding inner conductive sheets 20, so the second electromagnets 908 on the support plate 8 are in a powered-off state. Under this condition, the iron blocks 906 on the support plate 8 all move toward the corresponding first electromagnets 907, thereby driving all the beverage can placement nets 904 on the support plate 8 to tilt to the right.

[0081] When the two opposite inner conductive heads 18 are in contact with the corresponding inner conductive sheets 20, the second electromagnets 908 on the corresponding support plate 8 are in a powered-on state; at this time, the two outer conductive heads 16 corresponding to the support plate 8 are not in contact with the corresponding outer conductive sheets 19, so the first electromagnets 907 on the support plate 8 are in a powered-off state. Under this condition, the iron blocks 906 on the support plate 8 all move toward the corresponding second electromagnets 908, thereby driving all the beverage can placement nets 904 on the support plate 8 to tilt to the left. The outer conductive sheets 19 and the inner conductive sheets 20 are staggered with each other, so that the first electromagnets 907 and the second electromagnets 908 can be alternately powered on and off, so that the beverage cans can swing back and forth, better contact with the hot water in the sterilizing kettle 1, and thus quickly perform sterilization.

[0082] It should be noted that each outer conductive sheet 19 and each inner conductive sheet 20 is located between the arc-shaped inner rack 12 and the arc-shaped outer rack 13, so that after each beverage placement component 9 on the pallet 8 is in a fully expanded state, the first electromagnet 907 and the second electromagnet 908 are alternately powered on and off to drive the beverage can to swing left and right, thereby ensuring that the beverage can has enough swinging space.

[0083] With the above structure, when the main rotating shaft 4 rotates counterclockwise until each beverage placement assembly 9 on the support plate 8 is fully unfolded, when the outer conductive head 16 contacts the outer conductive sheet 19, each first electromagnet 907 is in an energized state, so that the beverage can placement net cylinder 904 is turned rightward along the turning axis 903, thereby causing the beverage can to swing to the right. When the inner conductive head 18 contacts the inner conductive sheet 20, each second electromagnet 908 is in an energized state, so that the beverage can placement net cylinder 904 is turned leftward along the turning axis 903, thereby causing the beverage can to swing to the left, thereby causing the state of the beverage can to change continuously, and to contact the hot water more comprehensively.

[0084] Embodiment 2: The present invention also proposes a rapid sterilization method for beverage processing, which is applicable to the rapid sterilization device of embodiment 1, and comprises the following steps:

[0085] Step 1: Place beverage cans containing beverages on each beverage placement assembly 9; specifically, place the beverage cans one by one in the beverage can placement net cylinder 904;

[0086] Step 2: Push the transfer vehicle 2 into the sterilizing kettle 1 and close the kettle door;

[0087] Step 3: Using a water spray sterilization method, spray hot water in a mist onto the surface of the beverage can through nozzles on both sides and the top of the sterilizer 1 to sterilize the beverage in the beverage can;

[0088] Step 4: During the sterilization process, the power source 5 drives the main rotating shaft 4 to rotate slowly counterclockwise, thereby driving the two rotating rings 6 to rotate synchronously, and then driving each support plate 8 to rotate slowly along the main rotating shaft 4, and keeping each support plate 8 in a horizontal state at all times;

[0089] Step 5: When the support plate 8 rotates to a certain height (more than half the height of the fixed plate 3), the unfolding and retracting mechanism 10 drives the beverage placement components 9 on the support plate 8 to unfold each other, so that the beverage cans can be fully in contact with the hot water, thereby achieving rapid sterilization;

[0090] Specifically, when the gear 10029 is meshed with the arc-shaped outer rack 13, the connecting shaft 10027 is driven to rotate, thereby driving the worm 10022 to rotate, and then driving the two movable plates 1001 to move away from each other, so that the beverage placement components 9 on the support plate 8 are unfolded to each other.

[0091] Step 6: Keep the fully expanded state, rotate to a certain distance, and the expansion and retraction mechanism 10 drives the beverage placement components 9 on the support plate 8 to retract to each other to adapt to the radial accommodation space in the sterilizer 1;

[0092] Specifically, when the gear 10029 is meshed with the arc-shaped inner rack 12, the connecting shaft 10027 is driven to rotate, thereby driving the two movable plates 1001 to approach each other, and then driving the beverage placement components 9 on the support plate 8 to fold together. It should be added that before the support plate 8 is lowered to half the height of the fixed plate 3, the beverage placement components 9 on the support plate 8 need to be in a completely folded state to ensure that they will not contact the retort 1 or other components in the retort 1.

[0093] In the process from fully unfolding to beginning to fold, the first electromagnets 907 and the second electromagnets 908 on the support plate 8 are alternately turned on and off, so that the beverage cans can swing back and forth left and right, and can be more fully in contact with hot water, without dead corners, the sterilization effect is effectively guaranteed, and the sterilization efficiency is greatly improved.

[0094] Step 7: After the sterilization is completed, open the kettle door, push the transfer vehicle 2 out of the sterilization kettle 1, and then take out the beverage cans.
