Description

Technical Field

[0001] This utility model belongs to the field of apple juice production technology, specifically relating to a high-temperature sterilization device for apple juice production. Background Technology

[0002] Apple juice beverages are juice products made from apples through physical methods such as pressing, centrifugation, and extraction. They generally refer to pure apple juice or 100% apple juice. Apple juice is classified into clear apple juice and cloudy apple juice according to its form. It is currently very popular among consumers and has a good market prospect.

[0003] After apple juice is extracted, it needs to be sterilized at high temperature before it can be bottled and sold. Apple juice usually contains a certain amount of protein. When heated for sterilization, the spatial structure of the protein changes, reducing its solubility and causing it to aggregate and form flocculation. Existing sterilization devices discharge the apple juice directly through the discharge pipe after high-temperature sterilization, causing the flocculation to be discharged along with it. This necessitates further filtration of the discharged apple juice before packaging, making the apple juice production process more complicated. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This specific embodiment is a high-temperature sterilization device for apple juice production, and its structural schematic diagram is shown below. Figure 1 and Figure 2 As shown, the device includes a sterilization tank 1, a tank cover 2 installed on the upper side of the sterilization tank 1, an indicator 3 installed on the upper front end of the sterilization tank 1, a pressure relief valve 4 installed on the right end of the tank cover 2, a discharge pipe 5 fixedly connected to the lower right end of the sterilization tank 1, a valve installed on the left end of the discharge pipe 5, a feeding mechanism provided on the upper end of the tank cover 2, the feeding mechanism including a feeding frame 601 fixedly connected to the upper left end of the tank cover 2, a support block 602 fixedly connected to the middle position of the inner perimeter of the feeding frame 601, a rectangular frame 603 connected to the inner side of the feeding frame 601, a first filter screen 604 fixedly connected to the inner side of the rectangular frame 603, the outer perimeter of the rectangular frame 603 slidably connected to the inner side of the feeding frame 601, the upper side of the support block 602 abutting against the lower side of the rectangular frame 603, and a feeding port opened inside the tank cover 2 below the feeding frame 601. After the rectangular frame 603 is placed from top to bottom along the inner side of the feed frame 601, the rectangular frame 603 will slide down along the inner side of the feed frame 601 to the upper side of the support block 602, and be supported and fixed to the inner side of the feed frame 601 by the support block 602. At the same time, the first filter screen 604 is fixed in the feed frame 601, so that the apple juice poured into the sterilization tank 1 through the feed frame 601 will be filtered by the first filter screen 604 to remove the residual apple pulp in the juice.

[0028] The upper side of the feed frame 601 is connected to a sealing plate 605, and the upper right side of the feed frame 601 is hinged to the right side of the sealing plate 605. An upper fixing block 606 is fixedly connected to the middle position of the left side of the sealing plate 605. A threaded rod 607 is connected inside the upper fixing block 606, and a rotating handle 608 is welded to the upper end of the threaded rod 607. A lower fixing block 609 is fixedly connected to the middle position of the upper left side of the feed frame 601. A first threaded hole is opened in the middle position of the upper fixing block 606, and a second threaded hole is opened in the middle position of the lower fixing block 609. The outer side of the threaded rod 607 is threadedly connected to the inner side of the first and second threaded holes. The upper side of the feed frame 601 abuts against the four corners of the lower side of the sealing plate 605. By rotating the sealing plate 605 to the upper side of the feed frame 601, and then threading the threaded rod 607 into the first threaded hole inside the upper fixing block 606 and then into the second threaded hole inside the lower fixing block 609, the upper fixing block 606 and the lower fixing block 609 can be fixed relative to each other, thereby fixing the sealing plate 605 to the upper side of the feed frame 601, sealing the upper end of the feed frame 601, and preventing heat from being rapidly lost from the top of the feed frame 601 during the high-temperature sterilization process inside the sterilization tank 1.

[0029] Cooperate Figure 3 and Figure 4 The sterilization tank 1 is equipped with sterilization mechanisms at both its inner and outer ends. The sterilization mechanism includes a heating wire 701 installed inside the tank wall of the sterilization tank 1. A motor 702 is installed at the middle position on the upper side of the tank cover 2. A rotating shaft 703 is fixedly connected to the lower end of the output shaft of the motor 702. An agitator 704 is fixedly connected to the outer side of the rotating shaft 703.

[0030] Cooperate Figure 5The discharge pipe 5 is equipped with a filter mechanism, which includes a vertical plate 801 fixedly connected to the inside of the discharge pipe 5. A stainless steel bearing 802 is installed in the middle of the vertical plate 801. A rotating shaft 803 is fixedly connected to the inside of the stainless steel bearing 802. A fan blade 804 is fixedly connected to the left end of the rotating shaft 803. A scraper 805 is fixedly connected to the outer side of the right end of the rotating shaft 803. An annular frame 806 is connected to the right end of the inside of the discharge pipe 5. A first... The second filter screen 807 and the annular frame 806 are fixedly connected to the upper and lower sides of the right side with connecting rods 808. The right end of the connecting rod 808 is welded with a connecting block 809. The left end of the connecting block 809 away from the connecting rod 808 is fixedly connected with a connecting ring 810. The outer side of the right end of the discharge pipe 5 is provided with an external thread, and the inner side of the connecting ring 810 is provided with an internal thread. The outer side of the right end of the discharge pipe 5 is threaded with the inner side of the connecting ring 810. The outer circumferential surface of the annular frame 806 is slidably connected with the inner side of the discharge pipe 5. By sliding the annular frame 806 to the inside of the discharge pipe 5 and threading the annular frame 806 to the outside of the right end of the discharge pipe 5, the second filter screen 807 can be installed on the right end of the inside of the discharge pipe 5. This allows the apple juice discharged from the sterilization tank 1 through the discharge pipe 5 to be filtered by the second filter screen 807. The flocculated material inside the apple juice is filtered by the second filter screen 807 and left on the left end of the second filter screen 807, and will not be discharged with the apple juice. As a result, the discharged apple juice can be directly bottled without further filtration, shortening the apple juice production process.

[0031] The right side of the scraper 805 is slidably connected to the left side of the second filter screen 807. When the apple juice inside the sterilization tank 1 is discharged through the discharge pipe 5, the apple juice flows to the fan blade 804, causing the fan blade 804 to rotate. This causes the rotating shaft 803 to rotate, driving the scraper 805 to rotate along the left side of the second filter screen 807. As a result, the flocculated material accumulated on the left side of the second filter screen 807 during filtration is continuously scraped off, preventing the flocculated material from completely clogging the left side of the second filter screen 807 and affecting the filtration process of the apple juice.

[0032] Working principle: During the high-temperature sterilization of apple juice, the apple juice is first poured into the feed frame 601. The apple juice in the feed frame 601 is then filtered through the first filter screen 604 to remove apple residue before falling into the sterilization tank 1 through the lower feed inlet. Next, the sealing plate 605 is rotated to the upper end of the feed frame 601. The sealing plate 605 is then fixed by threading the threaded rod 607 into the upper fixing block 606 and the lower fixing block 609. Subsequently, the heating wire 701 inside the sterilization tank 1 is energized, causing it to generate heat. The amount of apple juice inside the sterilization tank 1 is heated, and the output shaft of the motor 702 is started, which drives the rotating shaft 703 and the stirring blade 704 to rotate, stirring the apple juice inside the sterilization tank 1 so that it is heated and sterilized evenly. After the sterilization work is completed, the motor 702 and the power supply to the heating wire 701 are turned off. Finally, the valve at the left end of the discharge pipe 5 is opened, so that the sterilized apple juice in the sterilization tank 1 is filtered by the second filter screen 807 in the discharge pipe 5 to remove the flocculation inside, and then discharged from the right end of the discharge pipe 5 and collected.

[0033] All technical features in this embodiment can be freely combined according to actual needs.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
