[0002] Compound fruit and vegetable juice products are rich in pure natural nutrients such as various vitamins, oligosaccharides, organic acids and active substances, and have significant effects on improving nutritional health, regulating gastrointestinal function, and enhancing immunity. In the process of preparing and sterilizing compound fruit and vegetable juice products, in order to maintain the color, aroma, taste, nutritional components and freshness of the fruit and vegetable juice, ultra-high pressure and low temperature sterilization (HPP) technology is currently used to sterilize the fruit and vegetable juice.

[0003] HPP ultra-high pressure technology is to place packaged food under a static liquid pressure of 100-600MPa for a certain period of time, thereby destroying enzymes, sterilizing, and improving material structure and properties. Its sterilization mechanism is to change the protein and enzyme structure of microbial cells, inhibit enzyme activity, and kill a large number of pathogenic bacteria and spoilage bacteria in juice, while the sensory and nutritional value of food will not be affected. Therefore, HPP ultra-high pressure technology is widely used in the field of juice.

[0004] Existing HPP ultra-high pressure sterilization equipment is divided into two types: vertical and horizontal. The horizontal type has the advantages of convenient placement and retrieval of materials and easy to use with a conveying mechanism, but it occupies a larger area and has certain requirements on the area of ​​the factory. The vertical HPP ultra-high pressure sterilization equipment has the advantage of a smaller footprint than the horizontal type, but it is not convenient for placing and taking materials. In view of this, an HPP ultra-high pressure sterilization equipment is proposed which is convenient for taking and placing materials and does not have a large requirement on the factory area to solve the above problems.

[0049] Embodiment 2:

[0050] Reference Figure 1-Figure 9 , a preparation device for preparing composite fruit and vegetable juice using ultra-high pressure technology, used for a method for preparing composite fruit and vegetable juice using ultra-high pressure technology, comprising a tank cover 2, the tank cover 2 is sealed and clamped at the tank mouth of an ultra-high pressure container tank 1 through a sealing groove, the tank cover 2 can be lifted and connected to the ultra-high pressure container tank 1 through a hydraulic telescopic cylinder 4, the bottom of the tank cover 2 is symmetrically connected with a first slide rail 203, two sides of the tank cover 2 are symmetrically fixedly connected with two extension plates 201, the bottom of the extension plate 201 is symmetrically fixedly connected with a second slide rail 204 used in conjunction with the first slide rail 203, the open end of the containing basket 3 is fixedly connected with a fixed frame 301, and the fixed frame 301 can slide on the symmetrically arranged first slide rail 203 and the symmetrically arranged second slide rail 204.

[0051] When installing the equipment, first move the equipment between the loading conveying mechanism and the unloading conveying mechanism, and make the two extension plates 201 located directly above the loading conveying mechanism and the unloading conveying mechanism respectively. After the position adjustment of the two extension plates 201 is completed, the ultra-high pressure container tank 1 can be fixed to the ground by the ground bolts. When the filling of the composite fruit and vegetable juice is completed and the next ultra-high pressure sterilization treatment is required, the staff first stacks the soft packaging cans containing the composite fruit and vegetable juice in the filling basket 3, and then the filling basket 3 containing the stack of soft packaging cans can be placed on the conveyor belt of the loading conveying mechanism, and the position of the filling basket 3 is adjusted so that when the filling basket 3 is moved to the bottom of the extension plate 201, the fixed frame 301 on the filling basket 3 can just slide onto the two second slide rails 204.

[0052] When the containing basket 3 containing the flexible packaging can is placed on the conveyor belt of the loading conveying mechanism, the loading conveying mechanism can be started at this time, and the loading conveying mechanism will drive the containing basket 3 to move to the position of the ultra-high pressure container tank 1. When the fixed frame 301 on the containing basket 3 moves to the two second slide rails 204, the hydraulic telescopic cylinder 4 can be started at this time, and the hydraulic telescopic cylinder 4 will drive the can cover 2 to move up, and the can cover 2 will drive the containing basket 3 to move up through the extension plate 201 until it moves up to the top of the ultra-high pressure container tank 1. At this time, the containing basket 3 can be pushed onto the first slide rail 203, and then the can cover 2 can be controlled to move down until the can cover 2 is tightly attached to the can mouth of the ultra-high pressure container tank 1, so that the ultra-high pressure container tank 1 can be sealed and the containing basket 3 can be moved into the ultra-high pressure container tank 1, and then water can be injected into the ultra-high pressure container tank 1 and pressurized, so that the composite fruit and vegetable juice filled in the flexible packaging can can be subjected to ultra-high pressure and low temperature sterilization (HPP) treatment.

[0053] After the HPP treatment of the composite fruit and vegetable juice is completed, the pressure inside the ultra-high pressure container tank 1 can be relieved and the water can be drained. After the pressure relief and water drainage are completed, the tank cover 2 can be controlled to move up again, and the tank cover 2 will move the containing basket 3 out of the ultra-high pressure container tank 1, and then the containing basket 3 can be moved to the second slide rail 204 close to the unloading conveying mechanism, and then the tank cover 2 is controlled to move down, and the containing basket 3 can be placed on the unloading conveying mechanism, and then the unloading conveying mechanism can move the containing basket 3 to the next process for processing in the next process. At the same time, the loading conveying mechanism will move the containing basket 3 with the flexible packaging cans to be sterilized to the adjacent second slide rail 204, and then the tank cover 2 is controlled to rise and move down again, and the containing basket 3 with the flexible packaging cans to be sterilized can be moved to the ultra-high pressure container tank 1 for HPP treatment again, thereby repeatedly and continuously performing HPP treatment on the composite fruit and vegetable juice, effectively improving the preparation efficiency of the composite fruit and vegetable juice.

[0054] Embodiment 3:

[0055] Reference Figure 1-Figure 9 , a preparation device for preparing composite fruit and vegetable juice using ultra-high pressure technology, which is basically the same as Example 2, and further, multiple rollers 302 are equidistantly connected to the lower end of the fixed frame 301 on both sides, which are used to reduce the friction between the fixed frame 301 and the first slide rail 203 and the second slide rail 204. By arranging limiting rollers 302 on both sides of the fixed frame 301, the sliding connection between the fixed frame 301 and the first slide rail 203 and the second slide rail 204 can be converted into a rolling connection, thereby reducing the friction between the fixed frame 301 and the first slide rail 203 and the second slide rail 204, so that the filling basket 3 can be moved more easily.

[0056] A plurality of arc-shaped grooves are equidistantly provided on both sides of the fixed frame 301, and limit balls 303 are movably connected in the arc-shaped grooves. The limit balls 303 roll against the inner walls of the adjacent first slide rails 203 and second slide rails 204. By arranging the balls 303 on both sides of the fixed frame 301, the friction between the fixed frame 301 and the first slide rails 203 and the second slide rails 204 can be further reduced, thereby further improving the smoothness of the movement of the basket 3.

[0057] Embodiment 4:

[0058] Reference Figure 1-Figure 9 , a preparation device for preparing composite fruit and vegetable juice using ultra-high pressure technology, is basically the same as Example 3, and further, a plurality of arc-shaped protrusions 101 are fixedly connected to the inner wall of the ultra-high pressure container tank 1 at equidistant intervals in a circle, and the first slide rail 203 is rotatably connected to the tank cover 2.

[0059] A variable speed motor 206 is fixedly connected to the tank cover 2 , a rotating plate 205 is provided at the bottom of the tank cover 2 , an output end of the variable speed motor 206 is fixedly connected to the center position of the rotating plate 205 , and two first slide rails 203 are symmetrically fixedly connected to the rotating plate 205 .

[0060] When the basket 3 containing the product is placed in the ultra-high pressure container 1 for ultra-high pressure sterilization, the motor 206 can be started, and the motor 206 will drive the two first slide rails 203 to rotate through the rotating plate 205, and the first slide rails 203 will drive the basket 3 to rotate through the fixed frame 301, and then the basket 3 will be thrown to one side of the first slide rails 203 and intermittently contact the multiple arc-shaped protrusions 101, such as Figure 6 As shown, since there is a certain gap between every two adjacent arc-shaped convex columns 101, when the containing basket 3 rotates in a circle, it will rotate in a wave-like circle under the action of the arc-shaped convex columns 101, so that the containing basket 3 can be shaken back and forth in the water, and then the products piled together in the containing basket 3 will be loosened under the action of shaking and water flow, avoiding the problem of uneven pressure due to the accumulation of products, ensuring that the composite fruit and vegetable juice in the flexible packaging can can be sterilized evenly under pressure, and at the same time, it also avoids the problem that some products are over-pressurized, affecting the taste and quality, while other products cannot achieve the expected treatment effect due to insufficient pressure, effectively ensuring the sterilization effect of the composite fruit and vegetable juice, and at the same time, after completing the ultra-high pressure sterilization of the composite fruit and vegetable juice, the containing basket 3 can continue to be controlled to shake, so that the moisture on the surface of the flexible packaging can containing the composite fruit and vegetable juice can be shaken off, thereby improving the efficiency of subsequent removal of moisture from the surface of the flexible packaging can.

[0061] Embodiment 5:

[0062] Reference Figure 1-Figure 9 , a preparation device for preparing composite fruit and vegetable juice using ultra-high pressure technology, which is basically the same as Example 4, and further, a circle of annular grooves matching the position of the sealing grooves on the tank cover 2 is opened in the tank wall of the ultra-high pressure container tank 1, and a protective ring 102 is slidably connected in the annular groove, and a first magnetic ring 1021 is fixedly connected to the upper end of the protective ring 102, and a second magnetic ring 207 attracted to the first magnetic ring 1021 is fixedly connected in the sealing groove of the tank cover 2. Through the arrangement of the protective ring 102, the first magnetic ring 1021, and the second magnetic ring 207, when the tank cover 2 moves the containing basket 3 out of the ultra-high pressure container tank 1, the containing basket 3 can be moved up while the water droplets on the surface of the product can be shaken, which can not only improve the efficiency of removing moisture from the product surface in the subsequent process, but also block the water droplets thrown from the product surface to prevent the water droplets from being thrown everywhere.

[0063] A circle of first annular protrusions 103 is arranged near the notch of the annular groove, and a circle of second annular protrusions 104 used in conjunction with the first annular protrusions 103 is arranged at the bottom of the protective ring 102. Through the coordinated use of the first annular protrusions 103 and the second annular protrusions 104, when the basket 3 is about to be moved out of the ultra-high pressure container tank 1, the first annular protrusions 103 will abut against the second annular protrusions 104. When the basket 3 is completely moved out of the ultra-high pressure container tank 1, the first magnetic ring 1021 and the second magnetic ring 207 will separate under the cooperation of the first annular protrusions 103 and the second annular protrusions 104, so that the protective ring 102 can automatically fall back into the annular groove after the basket 3 is completely moved out of the ultra-high pressure container tank 1, thereby automatically causing the protective ring 102 to fall back.

[0064] One side of the extension plates 201 away from the tank cover 2 is rotatably connected to the limiting plate 202 through a rotating shaft. The extension plate 201 is located between the two second slide rails 204. The extension plate 201 on which the limiting plate 202 is installed is located on one side of the loading conveyor. Therefore, when the tank cover 2 and the extension plate 201 lift the basket 3 containing the processed product from the ultra-high pressure container tank 1, and lift the basket 3 containing the product to be processed, the limiting plate 202 can limit the basket 3 containing the product to be processed, thereby preventing the basket 3 containing the product to be processed from falling off the second slide rail 204 under the action of vibration, thereby effectively ensuring the protection effect of the product and the basket 3.

[0065] Embodiment 6:

[0066] Reference Figure 1-Figure 9 , a preparation device for preparing composite fruit and vegetable juice using ultra-high pressure technology, which is basically the same as Example 5, and further, a T-bar 208 is vertically inserted into the upper end of the tank cover 2, and the bottom of the T-bar 208 is designed in an arc shape, and arc-shaped positioning grooves 2012 used in conjunction with the T-bar 208 are symmetrically opened on the rotating plate 205, and a tension spring 209 is sleeved on the T-bar 208, and the two ends of the tension spring 209 are respectively fixedly connected to the tank cover 2 and the T-bar 208, and a rangefinder 2011 is installed at a position of the tank cover 2 close to the T-bar 208 through a bracket 2010, and the detection end of the rangefinder 2011 faces the T-bar 208.

[0067] After the ultra-high pressure sterilization of the product and the dehydration of the surface of the fruit and vegetable juice bottle are completed, the output power of the motor 206 can be slowly reduced, so that the rotating plate 205 can be controlled to slowly stop rotating. When the rotating plate 205 stops rotating, in order to ensure that the first slide rail 203 is aligned with the second slide rail 204 so that the basket 3 can slide out of the first slide rail 203, the motor 206 and the rangefinder 2011 can be started at the same time, so that the motor 206 drives the rotating plate 205 to rotate slowly. When one of the arc-shaped positioning grooves 2012 on the rotating plate 205 moves close to the T-bar 20 8, at this time, the lower end of the T-bar 208 will be inserted into the arc-shaped positioning groove 2012 under the tension of the tension spring 209, and then the rangefinder 2011 will detect the displacement of the T-bar 208, and then the main controller will know the first slide rail 203 to rotate to a position aligned with the second slide rail 204 according to the value detected by the rangefinder 2011, so that the main controller can control the rotating plate 205 to stop rotating through the motor 206, and then when the ultra-high pressure container tank 1 is moved out of the containing basket 3, the containing basket 3 can be quickly moved to the second slide rail 204 at the unloading end.
