Description

Technical Field

[0001] The present invention relates to the technical field of high-temperature sterilization, and in particular to a beverage high-temperature sterilization device and a sterilization method based on multi-stage circulation temperature control. Background Art

[0002] The working principle of high temperature sterilization equipment is mainly to kill harmful microorganisms by heating food to a certain temperature and keeping it for a period of time. This method is based on the destructive effect of high temperature on microorganisms, including protein denaturation, cell rupture and genetic material decomposition, thereby ensuring the safety of food.

[0003] In the process of preparing beverages, the above-mentioned sterilization principle is used to sterilize harmful microorganisms in the beverage raw materials.

[0004] Existing high-temperature sterilization equipment mainly utilizes high-temperature steam in the equipment to sterilize materials. During the sterilization process, the high-temperature steam diffuses and fills the sterilization equipment. Although this can achieve a good sterilization effect, once the high-temperature steam cools down, the sterilization effect will deteriorate. For this reason, the high-temperature steam in the existing high-temperature sterilization equipment is circulated by pumping, but there are also certain disadvantages. The main one is that the flow direction of the high-temperature steam is constant. As the high-temperature steam flows, the temperature of the high-temperature steam at the front end of the flow direction will drop, resulting in inconsistent temperature in the high-temperature sterilization equipment, and it is also unable to achieve a good sterilization effect.

DETAILED DESCRIPTION

[0051] 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.

[0052] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0053] See also Figures 1 to 10In an embodiment of the present invention, a high-temperature beverage sterilization device based on multi-stage circulation temperature control includes: a frame structure 1, a circulation structure and a switching component, so that when the high-temperature gas enters the loading tank 2, it can move horizontally or vertically. When moving horizontally, it cooperates with the rotation of the loading tank 2 to evenly sterilize the beverage in the loading tank 2. When moving vertically, it realizes longitudinal sterilization of the beverage. The coordination of the two movement directions of the high-temperature gas can ensure that the high-temperature gas is in full contact with the beverage, thereby improving the sterilization effect of the high-temperature gas on the beverage.

[0054] The frame structure 1 is provided with a matching loading tank 2 and an upper cover 3. Specifically, the upper cover 3 is rotatably connected with a plurality of groups of cylinders 4 provided on the frame structure 1, and a positioning block 301 is provided on the upper cover 3. Specifically, a connecting plate (not shown in the figure) is provided on the action end of the plurality of groups of cylinders 4, and the connecting plate is rotatably connected with the upper cover 3. The connecting plate is driven by the plurality of groups of cylinders 4 to move, so that the upper cover 3 can be lifted or lowered, so that the upper cover 3 can be closed or separated from the loading tank 2.

[0055] The loading tank 2 is provided with a positioning groove 202 , and the positioning groove 202 is adapted to the positioning block 301 . The adaptation method of the positioning groove 202 and the positioning block 301 includes that the positioning block 301 is placed in the positioning groove 202 so that the two are in a transversely engaged and limited state.

[0056] The frame structure 1 has a built-in driving device, which can make the loading tank 2 move in a circular motion, so that when the high-temperature gas enters the loading tank 2, it can contact the beverage more evenly, thereby performing a more even and comprehensive sterilization.

[0057] When the upper cover 3 is closed on the loading tank 2, it is necessary to align the positioning groove 202 with the positioning block 301, and when the upper cover 3 and the loading tank 2 are completely closed, the positioning block 301 is in a state of being embedded in the positioning groove 202. At this time, when the loading tank 2 rotates, the limiting effect of the positioning block 301 and the positioning groove 202 can be utilized to drive the upper cover 3 and the loading tank 2 to move synchronously, thereby preventing the upper cover 3 and the loading tank 2 from sliding against each other, thereby improving the airtightness when the two are closed, and effectively preventing the high-temperature gas entering the loading tank 2 from escaping from the joint between the upper cover 3 and the loading tank 2.

[0058] Among them, the side of the upper end of the positioning groove 202 is provided with a symmetrical inclined surface, which can guide the positioning block 301 to enter the positioning groove 202, and has an anti-fool effect, thereby improving the convenience of the two in the process of covering. Based on this, it can be extended that the upper end of the loading tank 2 is circumferentially equidistantly provided with a plurality of positioning grooves 202, and the relative inclined surfaces of two adjacent positioning grooves 202 are in a staggered state. At this time, there is no need to rotate the upper cover 3 to make the positioning block 301 cooperate with the designated positioning groove 202. The positioning block 301 can enter the corresponding positioning groove 202 according to its own position, so as to further improve the portability when the upper cover 3 and the loading tank 2 are covered.

[0059] See also Figure 1 to Figure 4 The flow structure is connected to the loading tank 2, and the flow structure includes an intake pipe 6, a first return pipe 7 and a second return pipe 10. The high-temperature gas entering the loading tank 2 through the intake pipe 6 can escape through the first return pipe 7 or the second return pipe 10;

[0060] Further, the loading tank 2 is provided with a plurality of groups of arc-shaped through grooves 201 at equal intervals on the circumference, and an annular cover 5 is installed on the loading tank 2 in a sealing and rotatable manner, the annular cover 5 is fixedly connected to the frame structure 1, and two communicating chambers 501 are symmetrically provided on the annular cover 5, one of the communicating chambers 501 is communicated with the air inlet pipe 6, and the other communicating chamber 501 is communicated with the first return pipe 7. It should be supplemented that the central angle of the opening of the communicating chamber 501 toward the loading tank 2 is greater than the connection point of the two adjacent arc-shaped through grooves 201, so that the high-temperature gas can continuously enter from the air inlet pipe 6 and escape from the first return pipe 7;

[0061] When the second return pipe 10 is in a blocked state, the high-temperature gas can move parallel to the central axis of the loading tank 2 .

[0062] When in use, the external high-temperature gas delivery device can pump the high-temperature gas into the air inlet pipe 6. At this time, the high-temperature gas enters the loading tank 2 through the connecting chamber 501 and the arc-shaped groove 201. When the second return pipe 10 is in a blocked state, the high-temperature gas entering the loading tank 2 can enter the first return pipe 7 through the arc-shaped groove 201 and the connecting chamber 501 on the other side. During this process, the high-temperature gas moves horizontally in the loading tank 2, and with the rotation of the loading tank 2, it can evenly contact the beverage in the loading tank 2 and sterilize it evenly.

[0063] The frame structure 1 is also connected to a collar 8, and the collar 8 is connected to the second return pipe 10 through a conduit 9;

[0064] The two ends of the loading tank 2 are also provided with a plurality of groups of conducting grooves 203 at equal intervals in a circumference, and the loading tank 2 is sealingly and rotatably connected with the collar 8;

[0065] When the first reflux pipe 7 is in a blocked state, the high-temperature gas can move along the length direction of the central axis of the loading tank 2 .

[0066] When the first reflux pipe 7 is in a blocked state, the high-temperature gas entering the loading tank 2 through the air inlet pipe 6 will escape from the conducting groove 203 and enter the second reflux pipe 10 through the conduit 9. During this process, the high-temperature gas entering the loading tank 2 can move along the central axis of the loading tank 2, that is, the high-temperature gas can move vertically in the loading tank 2, thereby achieving longitudinal sterilization of the beverage in the loading tank 2.

[0067] Through the above arrangement, when the high-temperature gas enters the loading tank 2, it can move horizontally or vertically. When moving horizontally, it cooperates with the rotation of the loading tank 2 to evenly sterilize the beverage in the loading tank 2. When moving vertically, it achieves longitudinal sterilization of the beverage. The coordination of the two movement directions of the high-temperature gas can ensure that the high-temperature gas is in full contact with the beverage, thereby improving the sterilization effect of the high-temperature gas on the beverage.

[0068] Furthermore, after flowing through the loading tank 2, the high-temperature gas can flow back to the external high-temperature gas delivery device through the first return pipe 7 or the second return pipe 10, and be reheated by the built-in heating device of the external high-temperature gas delivery device, and then be pumped again to realize the recycling of the high-temperature gas. Compared with the sterilization method of filling the loading tank 2 with high-temperature gas in the prior art, on the one hand, the directional mobility of the high-temperature gas is improved to ensure that the high-temperature gas can fully and effectively act on the beverage. On the other hand, less heat is dissipated during the circulation of the high-temperature gas, thereby reducing the energy consumption of the heating device for heating the high-temperature gas to a predetermined temperature.

[0069] It should be noted that, taking into account the different path lengths of the high-temperature gas from the loading tank 2 into the first return pipe 7 and the second return pipe 10, the high-temperature gas entering the heating device from the first return pipe 7 and the second return pipe 10 is heated to different degrees, while ensuring that the temperature of the high-temperature gas circulating in the loading tank 2 is consistent, energy consumption is further reduced.

[0070] See also Figure 5-6 The switching assembly is disposed on the frame structure 1 and connected to the first reflux pipe 7 and the second reflux pipe 10. The switching assembly can make the first reflux pipe 7 and the second reflux pipe 10 alternately connected, thereby changing the flow direction of the gas in the loading tank 2;

[0071] The switching assembly includes a guide rod 13 detachably connected to the frame structure 1, an electric telescopic rod 14 is fixedly mounted on the guide rod 13, and an action end of the electric telescopic rod 14 is connected to a rack plate 12 slidably mounted on the guide rod 13;

[0072] The switching assembly further includes two sets of rotary plugging structures respectively arranged in the first return pipe 7 and the second return pipe 10, one end of the rotary plugging structure is connected to a gear 11 meshing with the rack plate 12, and the rotary plugging structure includes a fixed ring 17 fixedly installed in the first return pipe 7 and the second return pipe 10, a rotating member 16 coaxial with the fixed ring 17 is slidably installed on the fixed ring 17, the rotating member 16 is sealingly and slidably fitted with the fixed ring 17, and a connecting rod 15 coaxially and fixedly connected with the gear 11 is arranged on the rotating member 16;

[0073] The fixing ring 17 and the rotating member 16 are both provided with an annular groove 18 . When the rotating member 16 rotates, the fixing ring 17 and the annular groove 18 on the rotating member 16 can be misaligned or overlapped.

[0074] In the present embodiment, two sets of rotary plugging structures are provided. For the convenience of understanding, the misalignment of the fixing ring 17 and the annular groove 18 on the rotating member 16 in the rotary plugging structure is called the blocking state, and the overlap of the fixing ring 17 and the annular groove 18 on the rotating member 16 in the rotary plugging structure is called the conducting state. At this time, in the initial state, there is only one set of rotary plugging structures in the blocking state, and the other set is in the conducting state, so that when the high-temperature gas enters the loading tank 2, it can escape from the first return pipe 7 or the second return pipe 10, that is, the high-temperature gas can move horizontally or vertically in the loading tank 2, and when the high-temperature gas moves horizontally or vertically in the loading tank 2 for a certain period of time, the electric telescopic rod 14 The rack plate 12 is moved, and the rack plate 12 is meshed with the two sets of gears 11, thereby driving the gears 11 to rotate, thereby causing the two rotating parts 16 in the two sets of rotary plugging structures to move, and causing the conduction states of the two sets of rotary plugging structures to change, that is, the rotary plugging structure that was originally in the blocked state is switched to the conducted state, and the rotary plugging structure that was originally in the conducted state is switched to the blocked state. At this time, the high-temperature gas can escape from the second return pipe 10 or the first return pipe 7 after entering the loading tank 2, thereby realizing the change of the movement direction of the high-temperature gas in the loading tank 2, so that the high-temperature gas can move periodically horizontally and vertically in the loading tank 2, and further improve the sterilization effect of the high-temperature gas on the beverage.

[0075] Through the above-mentioned arrangement, during the sterilization process, by controlling the movement of the electric telescopic rod 14, the conduction state of the two sets of rotary plugging structures can be periodically changed, so that the high-temperature gas entering the loading tank 2 can periodically escape from the first return pipe 7 or the second return pipe 10, thereby ensuring the periodic change of the movement direction of the high-temperature gas and further improving the sterilization effect of the high-temperature gas on the beverage.

[0076] See also Figure 7 to Figure 10 The beverage high temperature sterilization equipment based on multi-stage cycle temperature control also includes:

[0077] A carrier plate 19 is installed in the loading tank 2, and a plurality of dredging holes are provided on the carrier plate 19;

[0078] The embracing structure is provided with multiple groups and installed on the carrying plate 19. The embracing structure includes a first arc-shaped member 20 and a second arc-shaped member 21 provided on the carrying plate 19. The first arc-shaped member 20 cooperates with the second arc-shaped member 21 to fix the beverage placed on the carrying plate 19. The second arc-shaped member 21 is slidably connected with a transverse rod 22 provided in the loading tank 2.

[0079] The trigger assembly is connected to the second arc-shaped member 21 , and when the upper cover 3 moves toward the loading tank 2 , it can abut against the trigger assembly to drive the second arc-shaped member 21 to move toward the first arc-shaped member 20 .

[0080] In the initial state, the first arc-shaped member 20 and the second arc-shaped member 21 which cooperate to fix the beverage are in a separated state. At this time, the beverage to be sterilized can be placed on the supporting plate 19, and the beverage is placed between the first arc-shaped member 20 and the second arc-shaped member 21. When the upper cover 3 moves toward the loading tank 2 and the upper part of the loading tank 2 is blocked, the upper cover 3 can cooperate with the trigger assembly to drive the trigger assembly to move the second arc-shaped member 21 toward the first arc-shaped member 20, and clamp the beverage between the two. It has a certain positioning effect to prevent the beverage from moving and causing bumps and leakage when the loading tank 2 rotates. The beverages are evenly distributed, which is conducive to the flow of high-temperature gas between the beverages, further improving the sterilization effect of the high-temperature gas on the beverages.

[0081] The trigger assembly includes a lifting frame 25 disposed in the loading tank 2, and a sliding connection portion 2501 is provided on the lifting frame 25. The sliding connection portion 2501 is slidably connected to a guide member 26 disposed in the loading tank 2, and an abutment rod 27 is also installed on the lifting frame 25;

[0082] The trigger assembly further includes a cylindrical spring 28 connecting the lifting frame 25 and the guide member 26 and an interlocking structure connecting the second arc-shaped member 21 and the lifting frame 25;

[0083] The interlocking structure includes a vertical plate 23 fixedly connected to the second arc-shaped member 21, and a vertical slot 2302 and an inclined slot 2301 connected to the upper part of the vertical slot 2302 are provided on the vertical plate 23;

[0084] The sheave 24 rotatably mounted on the lifting frame 25 can roll in the vertical trough 2302 and the inclined trough 2301 .

[0085] In the initial state, the column spring 28 is in a stretched state, at which time the lifting frame 25 is at the highest point of the stroke, and the groove wheel 24 is at one end of the inclined groove body 2301 away from the vertical groove body 2302, so that the first arc member 20 is separated from the second arc member 21, so that the gap between the first arc member 20 and the second arc member 21 is more convenient for placing beverages, and when the upper cover 3 moves toward the loading tank 2, the upper cover 3 will abut against the abutment rod 27, and drive the lifting frame 25 to move downward along the length direction of the guide member 26, so that the groove wheel 24 moves The upper cover 3 moves downward, and the groove wheel 24 cooperates with the inclined groove body 2301 to drive the second arc-shaped member 21 to move toward the first arc-shaped member 20, and the beverage is fixed by the engagement between the second arc-shaped member 21 and the first arc-shaped member 20. When the upper cover 3 moves to fit with the loading tank 2, the groove wheel 24 will move into the vertical groove body 2302. At this time, the force of the groove wheel 24 reacting on the vertical groove body 2302 will not drive the groove wheel 24 and the lifting frame 25 to move upward, which further improves the sealing performance of the upper cover 3 and the loading tank 2 after the two parts are covered.

[0086] When the upper cover 3 moves away from the loading tank 2, the cylindrical spring 28 releases its elastic potential energy, and the abutment rod 27 can maintain the abutment state with the upper cover 3. At this time, the lifting frame 25 moves upward, and the groove wheel 24 moves along the vertical groove body 2302 in sequence with the inclined groove body 2301. When the groove wheel 24 moves in the inclined groove body 2301, the second arc-shaped member 21 can move away from the first arc-shaped member 20, thereby releasing the beverage to facilitate the removal of the beverage after sterilization is completed.

[0087] Through the above arrangement, when the upper cover 3 moves relative to the loading tank 2, the second arc-shaped member 21 can be driven to move toward or away from the first arc-shaped member 20, wherein when the second arc-shaped member 21 moves toward the first arc-shaped member 20, the beverage between the two can be clamped and have a certain positioning effect, thereby preventing the beverage from moving and causing bumps and leakage when the loading tank 2 rotates. Moreover, the beverages are evenly distributed, which is conducive to the flow of high-temperature gas between the beverages, further improving the sterilization effect of the high-temperature gas on the beverages.

[0088] As an embodiment of the present invention, a method for sterilizing beverages using a high-temperature sterilization device is also proposed, comprising the following steps:

[0089] Step 1: Connect the air inlet pipe 6, the first return pipe 7 and the second return pipe 10 to the external high-temperature gas delivery device through pipelines;

[0090] Step 2: Place the beverage to be sterilized on the carrier plate 19 in the loading tank 2, cover the upper cover 3, and fix the beverage by the engagement between the second arc-shaped member 21 and the first arc-shaped member 20;

[0091] Step 3: Control the loading tank 2 to rotate and start the external high-temperature gas delivery device at the same time;
