Technical Field
[0001] This utility model relates to the technical field of fruit juice beverage production equipment, and in particular to a highly efficient enzyme inactivation and sterilization device for fruit juice beverage production. Background Technology
[0002] In the production process of fruit juice beverages, enzyme inactivation and sterilization are key steps. Currently, there are some related technological achievements on the market, such as: (1) a mulberry juice enzyme inactivation and sterilization device (publication number CN205757068U), which uses a cooling pipe, a preheating pipe and an enzyme inactivation pipe composed of multiple U-shaped pipes to process mulberry juice, and controls the enzyme inactivation and sterilization temperature by controlling the steam pressure; (2) a fruit juice production sterilization device (publication number CN219396150U), which includes a sterilization tank for fruit juice sterilization and a tank cover installed at the mouth of the sterilization tank. A heating mechanism is installed inside the tank wall of the sterilization tank, and an ultraviolet lamp tube is connected to the center of the bottom of the tank; (3) a fruit juice beverage production sterilization device (publication number CN218831844U), which includes a storage tank, a feed pipe, a discharge pipe, a sterilization component, a cooling component and a conveying component. It can use the room temperature fruit juice in the storage tank to cool down the sterilized fruit juice, and at the same time preheat the room temperature fruit juice.
[0003] However, the aforementioned existing technologies have some shortcomings: on the one hand, some devices only use traditional methods such as steam heating or ultraviolet sterilization, which are not ideal for sterilization and cannot ensure the complete elimination of microorganisms and enzymes in the juice, thus affecting the shelf life of the beverage; on the other hand, some devices have relatively simple structures and have defects in extending the heating time of the juice and improving the uniformity of sterilization, which can easily lead to problems such as incomplete sterilization or local overheating, and can easily cause the loss of nutrients in the juice during the sterilization process, affecting the quality of the beverage. Utility Model Content
[0004] The purpose of this invention is to provide a highly efficient enzyme inactivation and sterilization device for fruit juice beverage production, which solves the problems of poor sterilization effect, easy loss of nutrients, and simple structure of some existing fruit juice beverage enzyme inactivation and sterilization devices, which cannot meet the requirements of efficient enzyme inactivation and sterilization.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A high-efficiency enzyme inactivation and sterilization device for fruit juice beverage production includes a heating cylinder, which is inclined and has a heating component on its wall. A spiral conveying shaft is rotatably arranged in the inner cavity of the heating cylinder, and the spiral conveying shaft is provided with spiral blades that match the inner wall of the heating cylinder. A drive component for driving the spiral conveying shaft to rotate is provided at one end of the heating cylinder.

A cooling component is connected to the end of the microwave sterilization component away from the heating cylinder, and a discharge port is provided at the end of the cooling component away from the microwave sterilization component.
[0007] Furthermore, the heating component is an electric heating tape spirally wound on a heating cylinder, and the electric heating tape has heating wires inside.

[0009] Furthermore, the drive assembly includes a drive motor and a gearbox, the output end of the drive motor is connected to the input end of the gearbox, and the output end of the gearbox is connected to the screw conveyor shaft.
[0010] Furthermore, a preheating assembly is provided in the inner cavity of the feed hopper, the preheating assembly including spirally distributed heating tubes. Through the heating tubes, the juice added to the feed hopper can be initially heated, achieving the purpose of preheating.
[0011] Furthermore, the feed hopper is also equipped with a stirring assembly, which includes a stirring shaft, a stirring paddle, and a stirring motor.

[0014] Furthermore, the microwave reflectors have a V-shaped cross-section, and several of them are staggered on both sides of the microwave radiation cavity. This arrangement allows microwaves to be evenly distributed within the microwave radiation cavity, covering every corner and improving the thoroughness of enzyme inactivation and sterilization.
[0015] Furthermore, the cooling assembly includes a hollow cooling box and cooling pipes disposed inside the cooling box, the cooling pipes being circulated with coolant.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.
[0025] Please refer to Figures 1-3 This embodiment provides a highly efficient enzyme-inactivating and sterilizing device for fruit juice beverage production, including a cylindrical heating cylinder 1, which is inclined. The cylinder wall of the heating cylinder 1 is equipped with a heating component. A spiral conveying shaft 11 is rotatably disposed within the inner cavity of the heating cylinder 1. Spiral blades 111, matching the inner wall of the heating cylinder 1, are welded onto the spiral conveying shaft 11. A driving component 2 for driving the spiral conveying shaft 11 to rotate is disposed at one end of the heating cylinder 1. A feed hopper 3 is connected to the top of the lower end of the heating cylinder 1, and a microwave sterilization component 4 is connected to the bottom of the upper end of the heating cylinder 1. A cooling component 5 is connected to the end of the microwave sterilization component 4 away from the heating cylinder 1, and a discharge port 511 is located at the end of the cooling component 5 away from the microwave sterilization component 4. The spiral conveying shaft causes the fruit juice to move spirally forward within the heating cylinder, and the inclined heating cylinder extends the sterilization time. The microwave sterilization component efficiently kills microorganisms and enzymes in the fruit juice using microwaves. The cooling component rapidly cools the sterilized fruit juice, ensuring its quality.
[0026] Through multi-stage processing, the enzyme inactivation and sterilization effects are significantly improved, effectively extending the shelf life of fruit juice beverages. Simultaneously, the ingenious structural design of the equipment, with all components working collaboratively, enhances production efficiency and maximizes the preservation of the fruit juice's nutritional components during the enzyme inactivation and sterilization process, ensuring beverage quality.
[0027] In some specific implementation methods, such as Figure 1 As shown, the main body of the feed hopper 3 is a cylindrical barrel with a conical bottom. The top of the feed hopper 3 has an inlet for adding juice.
[0028] In some specific implementation methods, refer to Figure 1 and Figure 2 The heating component is an electric heating tape 12 spirally wound on a heating cylinder 1, and the electric heating tape 12 has a heating wire inside. The heating cylinder 1 is equipped with a temperature sensor for monitoring the temperature. As an example, the heating temperature inside the heating cylinder 1 can be set to 80℃~90℃.
[0029] As an improved implementation method, refer to Figure 1 and Figure 2 The outer wall of the heating cylinder 1 is provided with an insulation layer 13 covering the heating components. This insulation layer reduces heat loss. For example, the insulation layer 13 can be a heat-resistant foam material.
[0030] In some specific implementation methods, refer to Figure 1 The drive assembly 2 includes a drive motor 21 and a reduction gearbox 22. The output end of the drive motor 21 is connected to the input end of the reduction gearbox 22, and the output end of the reduction gearbox 22 is connected to the screw conveyor shaft 11. In this way, the power of the drive motor can be transmitted to the screw conveyor shaft through the reduction gearbox, and the reduction gearbox can also adjust the transmission ratio according to the required speed to control the speed of the screw conveyor shaft. Specifically, the transmission speed is adjusted according to the viscosity of the juice; for example, the speed of the screw conveyor shaft can be set to 10 r / min to 50 r / min.
[0031] In some embodiments, a preheating component is provided in the inner cavity of the feed hopper 3 to achieve preheating. Specifically, refer to... Figure 1 The preheating assembly includes spirally distributed heating tubes 31. Thus, the juice added to the feed hopper can be initially heated by the heating tubes. As an example, the heating tubes 31 can be electric heating tubes. The feed hopper 3 is equipped with a temperature sensor for monitoring the temperature. The preheating temperature can be set to 70℃~80℃, and the preheating time can be set to 1min~2min.
[0032] As an improved implementation, the feed hopper 3 is also equipped with a stirring assembly. Specifically, refer to... Figure 1The stirring assembly includes a stirring shaft 32, stirring paddles 33, and a stirring motor 34. The stirring shaft 32 is vertically oriented and rotatably connected to the top of the feed hopper 3 via bearings. The output end of the stirring motor 34 is connected to the upper end of the stirring shaft 32, and the stirring paddles 33 are fixedly connected to the lower end of the stirring shaft 32. As an example, the stirring paddles 33 consist of multiple rods radially welded to the stirring shaft. By adding a stirring assembly to the feed hopper, the temperature of the juice is made more uniform during heating, preventing localized overheating or insufficient heating, and providing more stable conditions for subsequent enzyme inactivation and sterilization steps.
[0033] In some specific implementation methods, refer to Figure 1 and Figure 3 The microwave sterilization assembly 4 includes a microwave processing box 41 with a microwave radiation cavity 411 and at least one microwave generator 42 disposed inside the microwave radiation cavity 411. One end of the microwave processing box 41 has an input port connected to the heating cylinder 1 on its top wall, and the other end of the microwave processing box 41 has an output port connected to the cooling assembly 5 on its side wall. The microwave generator 42 is connected to a microwave power supply (not shown in the figure). After the microwave power supply is turned on, the microwaves generated by the microwave generator can efficiently sterilize the fruit juice by inactivating enzymes. Specifically, the microwave processing box 41 is rectangular. Preferably, multiple microwave generators 42 are provided to improve the enzyme sterilization effect. In addition, the microwave processing box 41 is externally provided with a protective structure (not shown in the figure). As an example, the microwave power of the microwave sterilization assembly can be set to 10kW~20kW, and the sterilization time can be approximately 20~60 seconds.
[0034] As an improved implementation method, refer to Figure 1 and Figure 3 The microwave radiation cavity 411 is provided with several microwave reflectors 43, which can reflect, diffuse and radiate microwaves evenly into the juice, thereby enhancing the contact effect between microwaves and juice and improving the enzyme inactivation and sterilization effect.
[0035] As a preferred embodiment, such as Figure 3 As shown, the microwave reflector 43 has a V-shaped cross-section, and several microwave reflectors 43 are staggered on both sides of the microwave radiation cavity 411. This arrangement allows microwaves to be evenly distributed within the microwave radiation cavity, covering all corners and improving the thoroughness of enzyme inactivation and sterilization. Simultaneously, these staggered microwave reflectors on both sides of the microwave radiation cavity further create a meandering channel within the cavity, thereby extending the flow time of the juice and promoting thorough sterilization.
[0036] In some specific implementation methods, refer to Figure 1 The cooling assembly 5 includes a hollow cooling box 51 and cooling pipes 52 disposed inside the cooling box 51, the cooling pipes 52 being circulated with coolant. Thus, the cooling pipes circulated with coolant can be used to rapidly lower the temperature of the juice after enzyme inactivation and sterilization, ensuring the preservation of the juice's nutritional components and flavor through timely cooling. Specifically, the cooling pipes 52 are serpentine stainless steel pipes to ensure service life, and are connected to a pump to drive the coolant flow, enabling the coolant to more efficiently lower the juice temperature to the ideal range, further improving the juice's quality. As an example, the coolant temperature can be set to 5℃~10℃, and the flow rate to 5L / min~10L / min.
[0037] In some specific embodiments, the feed hopper 3 is connected to the heating cylinder 1, the heating cylinder 1 is connected to the microwave processing box 41, and the microwave processing box 41 is connected to the cooling box 51 via flanges, which facilitates disassembly and maintenance, while ensuring the sealing of the connections of each component to prevent juice leakage.
[0038] In addition, the high-efficiency enzyme inactivation and sterilization device is also equipped with an electrical control box (not shown in the figure), which contains a control device for controlling its operation. As an example, the control device can be a conventional PLC controller with programmable functionality.
[0039] It should be noted that the electric heating tape 12, drive motor 21, gearbox 22, heating tube 31, stirring motor 34, and microwave generator 42 used in the above example are all conventional equipment structures and can be purchased directly through commercial channels.
[0040] The work process is as follows: Figures 1-3 As shown, when the juice is added from the feed inlet of the feed hopper 3, it undergoes initial heating under the action of the heating tube 31. It then flows into the heating cylinder 1, where the heating tape 12 continuously heats the juice. The drive motor 21 drives the spiral conveyor shaft 11 to rotate, and the spiral blades 111 spirally compress and push the juice upwards in a spiral motion, extending the heating time of the juice in the heating cylinder 1, allowing it to be fully heated to inactivate enzymes and sterilize. After entering the microwave sterilization component 4, the microwaves generated by the microwave generator 42 efficiently sterilize the juice. Finally, the juice, after enzyme inactivation and sterilization, flows into the cooling component 5. The coolant circulates within the cooling pipe 52 under the action of the circulating pump, absorbing heat from the juice through heat exchange, thereby rapidly reducing the temperature of the juice. The entire device effectively kills enzymes and microorganisms in the juice, and the timely cooling ensures the preservation of the juice's nutritional components and flavor.

Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
[0042] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
