Description

Technology Field

[0001] The present invention relates to a sterilization product loading platform for a retort sterilizer, wherein steam or water supplied to the sterilization chamber of the retort sterilizer moves smoothly to the lower part of the loading plate of the loading platform, thereby allowing heat exchange with the sterilization product placed on the loading plate, so that the packaged sterilization product is sterilized or cooled at a uniform temperature. Background Technology

[0003] Generally, when manufacturing retort foods, packaged sterilized products are placed in a sterilization chamber and cooled after sterilization treatment to ensure long-term preservation without the addition of preservatives or disinfectants.

[0004] Meanwhile, when introducing a packaged sterilized product into the sterilization chamber, as shown in FIG. 1, several retort sterilization stacks (200) containing packaged sterilized products are stacked and then introduced into the sterilization chamber (110) of the retort sterilization processor (100), thereby sterilizing a large amount of retort food simultaneously in the sterilization chamber (110).

[0005] Here, the sterilization product loading platform of a conventional retort sterilizer is composed of a loading plate having a plurality of cooling water discharge ports formed at predetermined intervals, and front and rear walls and side walls formed to protrude upward from the front and rear and left and right sides of the loading plate, respectively.

[0006] In this conventional retort sterilizer, the sterilization product loading platform prevents packaged food placed on the upper surface of the loading plate from falling outside the loading platform by means of front and rear walls and side walls, and at the same time, by stacking the loading platforms by placing the bottom surfaces of the front and rear walls and side walls of another loading platform in contact with the upper surfaces of the front and rear walls and side walls, it is possible to insert several packaged sterilization products into the sterilization chamber of the retort sterilizer for sterilization treatment.

[0007] However, in the case of stacking stacks of sterilized products in such conventional retort sterilizers to perform sterilization operations by introducing a large amount of packaged sterilized products into the sterilization chamber of the retort sterilizer, the sterilized products and the stacking plates are in contact with each other, so there is no gap for steam or water to enter. Consequently, the heat from the high-temperature steam or water supplied to the sterilization chamber is not uniformly supplied to the lower part of the sterilized products placed on the upper part of each stacking plate, and most of the heat exchange occurs on the upper surface of the sterilized products (packaged foods), which has a problem of taking a longer time during sterilization or cooling. Prior art literature

[0009] Republic of Korea Registered Patent No. 10-0531942 (Registered on Oct. 06, 2005) The problem to be solved

[0010] The objective of the present invention is to provide a loading platform for retort sterilization that solves the above-mentioned problems and enables appropriate sterilization and cooling of several packaged sterilized products placed on a loading platform to be introduced into the sterilization chamber of a retort sterilizer for sterilization and cooling treatment in a shorter time, even when several packaged sterilized products placed on the loading platform are introduced into the sterilization chamber of a retort sterilizer.

[0011] Another objective of the present invention is to provide a loading platform for retort sterilization that allows the loading platforms to be stacked vertically with the load distributed by means of an angle welded to the corner portion of the loading platform, where the front and rear walls and the bottom surfaces of the left and right side walls are each located at the bottom, and the lower surfaces of the front and rear walls and the side walls of other loading platforms being in contact with and supported by the upper surface of the loading platform where the angle welded to the corner portion. means of solving the problem

[0013] The present invention, for achieving the above-mentioned purpose, comprises a loading plate (210) having a plurality of cooling water discharge ports (211) formed at a predetermined interval, a front and rear wall (230) and a side wall (220) formed on the front and rear portions and left and right sides of the loading plate (210) so as to protrude upward, a through hole (212) formed through the center of the loading plate (210) through which steam is guided and passes, the height of the front and rear wall (230) formed on the front and rear portions of the loading plate (210) is formed higher than the height of the side walls (220) formed on the left and right sides of the loading plate (210), and an inlet hole (221) (231) having the same inner diameter is formed through the side wall (220) and the front and rear wall (230), wherein a protrusion (213) is formed at a predetermined interval so as to protrude upward in the loading plate (210) through which the cooling water discharge ports (211) are formed. It is achieved by forming multiple.

[0014] Meanwhile, it is noted that an angle (240) is welded to the corner portion of the above-mentioned loading platform (200), in which a first contact portion (241) that contacts the side wall (220) and a second contact portion (242) that contacts the front and rear walls (230) are integrally bent and formed.

[0015] Additionally, the angle (240) is formed higher than the height of the side wall (220), and the upper part of the angle (240) located at the same height as the side wall (220) is bent outward so that a support surface (241a) (242a) is formed on the first contact part (241) and the second contact part (242), so that the angle (240) welded to another loading platform (200) is seated and supported on the support surface (241a) (242a) formed on the first contact part (241) and the second contact part (242) of the angle (240), and the other loading platform (200) is stacked on the loading platform (200). Effects of the invention

[0017] According to the present invention, when another stacking platform is stacked on top of a stacking platform, a space is formed between the bottom surface of the side wall and the top surface of the stacking platform to allow steam and water to flow in. A through hole is formed through the stacking plate of the stacking platform to allow steam or water supplied to the sterilization chamber to flow into the center. Additionally, a plurality of protrusions are formed at regular intervals so that they protrude upwards through the stacking plate formed by the cooling water discharge port. Consequently, when a packaged sterilized product is placed on the stacking plate of the stacking platform and sterilization is performed using a retort sterilizer, the packaged sterilized product comes into contact with the protrusions formed on the stacking plate and maintains a state separated from the top surface of the stacking plate. As a result, the steam or water supplied to the sterilization chamber flows into the stacked stacking platform and is transferred to the stacking platform located below through the cooling water discharge port. Simultaneously, steam or water flows between the stacking platforms to perform sterilization, and through the through hole formed in the stacking plate, it flows into the center of the stacking platform, thereby having the effect of sterilizing several packaged sterilized products placed on the stacking platform at a rapid and uniform temperature.

[0018] Meanwhile, according to the present invention, even when stacking the loading platform vertically, it is a very useful invention that has the effect of being stably supported by the angle and stacked. Brief explanation of the drawing

[0024] As illustrated in FIGS. 1 to 6, the sterilization product loading platform of the retort sterilizer of the present invention comprises a loading plate (210) having a plurality of cooling water discharge ports (211) formed at a predetermined interval, and front and rear walls (230) and side walls (220) formed on the front and rear portions and left and right sides of the loading plate (210) so as to protrude upward. A through hole (212) through which steam and water are guided and passed is formed through the central portion of the loading plate (210). The height of the front and rear walls (230) formed on the front and rear portions of the loading plate (210) is formed to be higher than the height of the side walls (220) formed on the left and right sides of the loading plate (210). Inlet holes (221) (231) having the same inner diameter are formed through the side walls (220) and the front and rear walls (230).

[0025] Meanwhile, in the loading plate (210) formed by penetrating the above-mentioned cooling water discharge port (211), a plurality of protrusions (213) are formed at regular intervals so as to protrude upward. Additionally, the protrusions (213) have a conical shape.

[0026] In addition, an angle (240) is welded to the corner portion of the above-mentioned loading platform (200), in which a first contact portion (241) that contacts the side wall (220) and a second contact portion (242) that contacts the front and rear walls (230) are integrally bent and formed.

[0027] Meanwhile, the angle (240) is formed higher than the height of the side wall (220), and the upper part of the angle (240) located at the same height as the side wall (220) is bent outward so that a support surface (241a) (242a) is formed on the first contact part (241) and the second contact part (242), so that the angle (240) welded to another loading platform (200) is seated and supported on the support surface (241a) (242a) formed on the first contact part (241) and the second contact part (242) of the angle (240), and the other loading platform (200) is stacked on the loading platform (200).

[0028] In the present invention configured as described above, when several packaged sterilized products are placed on a loading platform (200) to perform sterilization treatment by introducing them into the sterilization chamber (110) of a retort sterilization processor (100), the packaged sterilized products come into contact with the protrusion (213) formed on the loading plate (210) and maintain a state separated from the upper surface of the loading plate (210).

[0029] When stacking a stacking platform (200) in which a sterilization product is placed so as to be spaced apart from the upper surface of a stacking plate (210) as described above, the bottom surface of the side wall (220) and the front and rear wall (230) of another stacking platform (200) comes into contact with the support surface (241a) (242a)) of an angle (240) in which a first contact part (241) and a second contact part (242) are respectively welded to the corner portion of the stacking platform (200), and the outer surface of the angle (240) welded to the corner portion of the other stacking platform (200) comes into contact with the upper inner surface of the first contact part (241) and the second contact part (242) of the angle (240) located at the bottom, thereby stably stacking.

[0030] It maintains the established state.

[0031] Meanwhile, when stacking another stacking platform (200) so as to be positioned on top of the stacking platform (200), a space (250) is formed between the bottom surface of the side wall (220) of the stacked other stacking platform (200) and the top surface of the side wall (220) of the stacking platform (200).

[0032] As described above, when multiple stacking units (200) are stacked to form a space (250) on the side wall (220) and then introduced into the sterilization chamber (110) of the retort sterilization processor (100), high-temperature steam or water is supplied to the sterilization chamber (110), the high-temperature steam or water supplied to the sterilization chamber (110) flows into the space (250) between the stacking units (200) and the stacking units (200) formed by stacking in layers, thereby sterilizing the sterilization products placed on the stacking plates (210) of the stacking units (200). The steam or water that has undergone heat exchange with the sterilization products flows into the sterilization products placed on the stacking plates (210) of the stacking units (200) located below through the cooling water discharge holes (211) formed in the stacking plates (210). The steam or water flowing into the stacking plates (210) so that the sterilization products placed on the stacking plates (210) are sterilized and cooled The product placed in the center of the loading plate (210) is sterilized at a fast and uniform temperature as it flows into the center of the loading plate (210) through the through hole (212) formed in the center of the loading plate (210).

[0033] In addition, the side wall (220) and the front wall (230) each have an inlet hole (221) (231) formed therein to allow high-pressure steam or water supplied to the sterilization chamber (110) of the retort sterilizer (100) to be introduced into the upper part of the loading plate (210), thereby allowing a large amount of high-temperature steam or water introduced into the sterilization chamber (110) of the retort sterilizer (100) to be introduced into the upper part of the loading plate (210) of the loading stand (200), so that the sterilization work can be completed efficiently in a short time when sterilizing items packaged using the retort sterilizer (100).

[0034] Meanwhile, on both the left and right sides of the through hole (212) formed in the center of the loading plate (210) of the loading stand (200), reinforcing protrusions (214) are formed by bending them to protrude upward from the loading plate (210) so as not to block the through hole (212) by the sterilization product placed on the upper part of the loading plate (210) and to prevent sagging of the loading plate (210) due to the load of the sterilization product. This ensures that the through hole (212), which allows steam to flow into the center of the loading plate (210) by the sterilization product placed on the loading plate (210) of the loading stand (200), is not blocked, and at the same time, the sterilization product is not damaged by the heat of high-temperature steam or water flowing into the center of the loading plate (210) through the through hole (212).
