Technical Field

[0001] The utility model belongs to the technical field of beverage production, and in particular relates to a sterilization device for producing fruit juice beverages. Background Art

[0002] Fruit juice drink refers to a beverage made from fresh fruit juice. The juice of various fruits contains different vitamins and other nutrients, and is considered to be a drink that is beneficial to health. The pace of life in modern society is getting faster and faster, and many people rarely eat vegetables and fruits. Fruit juice drinks are favored by people because of their good taste. Fruit juice drinks can supplement people with nutrition and water. The processing of fruit juice drinks involves raw material selection, cleaning, crushing, pulping, juicing, screening, centrifugal separation, clarification, filtration, blending, sterilization, filling, cooling and other processes. Among them, sterilization not only directly affects the quality of fruit juice drinks, but also affects the health of the drinkers.

[0003] Thermal sterilization is a commonly used sterilization method in juice production. Existing thermal sterilization equipment is relatively large in size. For example, a sterilization device for juice beverage production disclosed in the utility model patent with authorization announcement number CN220211781U includes a sterilization pot and a movable plate. By pulling the handle outward, the movable plate is driven to move outward. When the roller is out of contact with the fixed plate, the reset spring will extend and reset, and push one end of the support column to move downward around the first fixed block, driving the seat and the roller to move downward, so that the roller contacts the ground, thereby supporting the support column between the movable plate and the ground.

[0004] The above structure occupies a large area, the equipment is large and complex in structure, requires a large space for use, and has high energy consumption, which is not conducive to reducing the control of product production costs. Utility Model Content

[0015] As a further improvement of the above technical solution: the number of the electric heating tubes is multiple and they are arranged around the axis of the outer tube body, and a pressure relief valve is installed on the top of the outer tube body.

[0016] The beneficial effect of this improvement is that the multiple thermometers can evenly heat the heat medium in the jacket after being powered on, thereby ensuring the uniformity of heating of the inner tube body.

[0017] In order to safely and effectively heat the heat medium in the water tank;

[0018] As a further improvement of the above technical solution: an exhaust port is provided on the top of the water tank.

[0019] The beneficial effect of this improvement is that the volatilized gas after the heat medium in the water tank is heated can be discharged through the exhaust port, avoiding safety hazards caused by pressure buildup in the water tank.

[0020] In order to effectively extend the sterilization time of juice in the constant temperature heating mechanism;

[0021] As a further improvement of the above technical solution: the coil is a serpentine coil structure.

[0022] The beneficial effect of this improvement is that the coil of the serpentine tube structure can effectively reduce the floor space occupied by the constant temperature heating mechanism while increasing the passage time of the juice in the constant temperature heating mechanism.

[0023] In order to obtain the sterilization temperature information of the device accurately and timely;

[0024] As a further improvement of the above technical solution: Thermometer 2 is installed on the outer tube body and the probe of thermometer 2 is inserted in the jacket, thermometer 1 is installed on one end of the inner tube body connected to the coil, and thermometer 3 is installed on the water tank.

[0025] The beneficial effect of this improvement is that the thermometer 1, the thermometer 2 and the thermometer 3 can respectively monitor the internal temperature of the feedback jacket and the water tank and the temperature of the juice when it flows out of the rapid heating mechanism.

[0026] In order to achieve automatic control of the device temperature;

[0027] As a further improvement of the above technical solution: a temperature controller is installed on the rapid heating mechanism, and the temperature controller is electrically connected to thermometer 1, thermometer 2, thermometer 3 and electric heating tube 1 and electric heating tube 2.

[0028] The beneficial effect of this improvement is that the temperature controller can receive the temperature signals fed back by thermometer 1, thermometer 2 and thermometer 3, and then automatically control the working state of the pair of electric heating tubes 1 and 2, so that the internal temperature of the jacket and the water tank is controlled within a preset temperature range.

During the flow in the coil 21, the constant temperature is maintained for effective sterilization. The arrangement of the unpowered stirring blade 12 effectively simplifies the device structure while ensuring that the juice is evenly heated and sterilized, and reduces the size and operating cost of the device. A regulating valve 3 is installed between the inner tube body 11 and the coil 21. When the juice pumping pressure, i.e., the initial water flow pressure, remains unchanged, the operator can adjust the flow of the juice in the coil 21 by controlling the valve path size of the regulating valve 3, thereby changing the sterilization time of the juice conveniently and quickly to ensure the sterilization effect. The unpowered stirring blade 12 is composed of a plurality of spiral plate structures adjacent to each other, and the angle between the two adjacent spiral plates is 90 degrees. Under the flow potential energy of the juice, the juice is blocked and guided by the unpowered stirring blades 12 to achieve the stirring effect, so that the juice as a whole can fully contact the inner wall of the coil 21 and the inner tube body 11 during the flow in the inner tube body 11 and the coil 21, so as to be evenly and effectively heated. The number of the electric heating tubes 15 is multiple and they are arranged around the axis of the outer tube body 13. A pressure relief valve is installed on the top of the outer tube body 13. After the multiple thermometers 5 are powered on, the heat medium in the jacket 14 can be evenly heated to ensure the uniformity of the heating of the inner tube body 11. An exhaust port 25 is opened on the top of the water tank 23. The volatilized gas after the heat medium in the water tank 23 is heated can be discharged through the exhaust port 25 to avoid the safety hazard caused by the pressure in the water tank 23. The coil 21 is a serpentine coil The coil 21 of the serpentine tube structure can effectively reduce the floor space of the constant temperature heating mechanism 2 while increasing the passage time of the juice in the constant temperature heating mechanism 2. The outer tube body 13 is equipped with a thermometer 2 6 and the probe of the thermometer 2 6 is inserted in the jacket 14. The end of the inner tube body 11 connected to the coil 21 is equipped with a thermometer 1 5. The water tank 23 is equipped with a thermometer 3 7. The thermometer 1 5, the thermometer 2 6 and the thermometer 3 7 can respectively monitor the internal temperature of the feedback jacket 14 and the water tank 23 and the temperature of the juice when it flows out of the rapid heating mechanism 1. The rapid heating mechanism 1 is equipped with a thermostat 4, and the thermostat 4 is electrically connected to the thermometer 1 5, the thermometer 2 6, the thermometer 3 7 and the electric heating tube 1 15 and the electric heating tube 2 22.The temperature controller 4 can receive the temperature signals fed back by the thermometer 1 5, the thermometer 2 6 and the thermometer 3 7, and then automatically control the working state of the electric heating tube 1 15 and the electric heating tube 2 22, so that the internal temperature of the jacket 14 and the water tank 23 is controlled within the preset temperature range.

[0038] The working principle of the present technical solution is as follows: the juice enters the device through pumping or other means for sterilization; first, the electric heating tube 1 15 and the electric heating tube 2 22 are started by the thermostat 4, so that the electric heating tube 1 15 and the electric heating tube 2 22 heat the heat medium in the jacket 14 and the water tank 23 to a suitable process temperature respectively, and the heat medium then heats the temperature of the inner tube body 11 and the coil 21 by heat transfer, and the temperature monitoring and feedback are realized by the thermometer 2 6 and the thermometer 3 7; when the juice enters the inner tube body 11, it impacts the non-powered stirring blade 12 under the action of the potential energy of the water flow, and the juice is fully in contact with the inner wall of the inner tube body 11 under the guidance and blocking of the non-powered stirring blade 12, so that the juice is quickly in the process of passing through the inner tube body 11 After being heated to a suitable sterilization temperature, the temperature feedback of the juice is realized through a thermometer 5; then the juice enters the coil 21, at which time the temperature of the coil 21 should be close to the temperature of the juice when it flows out of the rapid heating mechanism 1, and be within a suitable sterilization temperature range, so that the juice can be effectively sterilized by constant temperature heating in the process of flowing through the coil 21; the speed at which the juice passes through the coil 21, that is, the duration of sterilization, can be realized by controlling the valve path size of the regulating valve 3; when the juice passes through the coil 21, it impacts the unpowered stirring blade 12 under the action of the potential energy of the water flow, and the juice is fully in contact with the inner wall of the coil 21 under the guidance and blocking of the unpowered stirring blade 12, so that the juice is always kept at a suitable sterilization temperature in the process of passing through the coil 21.
