Description

Technical Field

[0001] The invention relates to the field of food production, and in particular to a method for preparing a salted egg yolk vacuum oil reservoir. Background Art

[0002] Salted egg yolk vacuum oil storage is a food preservation method, the process is to prepare salted egg yolk soaked in oil and then vacuum packed to extend the shelf life of the salted egg yolk and maintain its flavor, this method is usually widely used in commercial production.

[0003] During the salted egg yolk vacuum storage process, a series of quality tests are required to ensure product quality and safety. These tests include but are not limited to raw material inspection, microbial inspection, physical and chemical index inspection, packaging material inspection, vacuum inspection, etc. The vacuum inspection is to randomly select a part of the products from the batch production to check the sealing of the packaging bag to ensure that there is no leakage.

[0004] Conventional vacuum degree detection methods include water immersion method, pressure decay method and negative pressure test method. Among them, water immersion method is widely used due to its low cost. The water immersion method is to directly immerse the product in water. On the one hand, observe whether there are bubbles escaping from the packaging bag, and on the other hand, observe whether there is oil on the water surface. If any of the two phenomena occurs, it means that there is a leak in the packaging bag.

[0005] Currently, when testing the vacuum degree of a product through the water immersion method, multiple samples are generally tested one by one, which leads to a long testing time and relatively low testing efficiency. In addition, the oil leaked from the problematic sample will contaminate the testing container, which must be cleaned before the next sample can be tested, further reducing the testing efficiency.

DETAILED DESCRIPTION

[0033] The embodiments of the present invention are described in detail below with reference to the accompanying drawings, but the invention can be implemented in many different ways as defined and covered by the claims.

[0034] See also Figure 2 A method for preparing a salted egg yolk vacuum oil reservoir is completed by a sealing detection device, which includes an H-shaped bracket 1, a U-shaped support plate 2, an immersion mechanism 3, a cylinder 4, a lifting mechanism 5, a clamping mechanism 6 and a cleaning mechanism 7. The H-shaped bracket 1 is symmetrically arranged with two, and a U-shaped support plate 2 is fixedly connected between the horizontal sections of the two H-shaped brackets 1. A plurality of immersion mechanisms 3 are evenly connected to the U-shaped support plate 2 from left to right, and a cylinder 4 is fixedly connected to the lower end of the horizontal section of the H-shaped bracket 1. The piston rod of the cylinder 4 slides through the horizontal section of the H-shaped bracket 1 and extends upward. The piston rods of the two cylinders 4 are commonly connected with a lifting mechanism 5, and the lifting mechanism 5 is evenly connected with a plurality of clamping mechanisms 6 and cleaning mechanisms 7 corresponding to the immersion mechanisms 3 from left to right.

[0035] See also Figure 2 and Figure 3 The immersion mechanism 3 includes a transparent container 31, a water outlet pipe 32 and a valve 33. A plurality of transparent containers 31 with openings upward are evenly fixedly connected to the horizontal section of the U-shaped support plate 2 from left to right. The lower end of the transparent container 31 is fixedly connected to the water outlet pipe 32. The water outlet pipe 32 passes through the horizontal section of the U-shaped support plate 2 and extends downward. The bottom end of the water outlet pipe 32 is fixedly connected to the valve 33.

[0036] During the specific operation, during the first test, the valve 33 is in a closed state. At this time, a sufficient amount of clean water is put into each transparent container 31, and then the multiple samples randomly selected are clamped on each clamping mechanism 6 respectively, and then the cylinder 4 is started, and the lifting mechanism 5 is driven down by the cylinder 4, and then the clamping mechanism 6 and the cleaning mechanism 7 are driven to descend synchronously, so that the sample clamped by the clamping mechanism 6 is fully immersed in the clean water in the corresponding transparent container 31 for a period of time. An external camera is arranged in front of the transparent container 31. During the period when the sample is immersed in the clean water, the staff first observes whether there are bubbles in the clean water in each transparent container 31 through the camera. If there are bubbles, it means that the sample is leaking. However, sometimes the leakage point is small and the bubbles are not easy to be observed by the naked eye. Therefore, after the immersion is completed, it is necessary to check whether there is oil floating on the surface of the clean water in each transparent container 31 in turn, so as to more accurately detect the leakage of the sample.

[0037] After the first test is completed, the lifting mechanism 5 and the clamping mechanism 6 are driven to rise by the cylinder 4. The intact samples are directly removed and replaced with new samples. For samples with leakage, the valve 33 on the water outlet pipe 32 below the transparent container 31 where the leaking sample is located is first opened to release the sewage, and then the sample at this location is removed, and the cleaning mechanism 7 at this location is adjusted to be directly below. When the second test is carried out, the test in the uncontaminated transparent container 31 is carried out normally, and the clamping mechanism 6 at the contaminated location does not clamp the sample, and the cleaning mechanism 7 will automatically clean the transparent container 31 at this location until the third test. After the contaminated transparent container 31 is cleaned, the valve 33 on the water outlet pipe 32 below it is closed again, and clean water is re-added to the transparent container 31 at this location. At the same time, the clamping mechanism 6 is adjusted to the bottom to clamp the sample, and the test is carried out together with the remaining transparent containers 31.

[0038] See also Figure 2 , Figure 3 and Figure 4 The lifting mechanism 5 includes a T-shaped seat 51, a mounting rod 52, a connecting seat 53 and a locking assembly 54. The upper end of the piston rod of the cylinder 4 is fixedly connected with the T-shaped seat 51. The T-shaped seat 51 is slidably connected between the two vertical sections of the H-shaped bracket 1. The vertical sections of the two T-shaped seats 51 are commonly fixedly connected with the mounting rod 52. The mounting rod 52 is evenly rotatably connected with multiple connecting seats 53 from left to right. The connecting seat 53 includes a sleeve 531 rotatably sleeved on the mounting rod 52 and three connecting pipes 532 evenly fixedly connected to the side wall of the sleeve 531 along the circumferential direction. The front and lower connecting pipes 532 are connected with a clamping mechanism 6, and the rear connecting pipe 532 is connected with a cleaning mechanism 7. The sleeve 531 and the mounting rod 52 are commonly connected with a locking assembly 54.

[0039] See also Figure 4 and Figure 5The locking assembly 54 includes a slide groove 541, a slider 542, a pressure spring 543, an annular slide plate 544, a block 545 and a slot 546. The side wall of the mounting rod 52 is symmetrically provided with slide grooves 541 at positions on the left and right sides of the sleeve 531. The slide groove 541 is slidably connected with a slider 542. The end surface of the slider 542 away from the sleeve 531 and the end surface of the slide groove 541 away from the sleeve 531 are commonly connected with a pressure spring 543. The slider 542 is fixedly connected with an annular slide plate 544. The annular slide plate 544 is slidably sleeved on the mounting rod 52. The end surface of the annular slide plate 544 close to the sleeve 531 is evenly and fixedly connected with three blocks 545 along the circumferential direction. The left and right end surfaces of the sleeve 531 are both provided with slots 546 matched with the blocks 545. The blocks 545 are slidably connected in the slots 546.

[0040] In specific operation, the connecting tube 532 at the bottom is named as the No. 1 connecting tube 532, and the other two connecting tubes 532 are named as the No. 2 connecting tube 532 and the No. 3 connecting tube 532 in a counterclockwise direction from left to right. Before the test, the T-shaped seat 51 is located at a relatively upper position of the vertical section of the H-shaped bracket 1. At this time, the annular slide 544 is pressed against the sleeve 531 by the pressure of the pressure spring 543, and the clamping block 545 is clamped in the clamping groove 546, so that the No. 1 connecting tube 532 can be fixed. At the bottom, when the positions of the three connecting tubes 532 need to be switched, it is necessary to first slide the circular slide plate to disengage the block 545 from the slot 546. At this time, the connecting seat 53 can rotate freely. At this time, adjust the No. 2 connecting tube 532 or the No. 3 connecting tube 532 to the bottom as needed, and then release the annular slide plate 544. The annular slide plate 544 is pressed against the sleeve 531 again under the pressure of the pressure spring 543, and the block 545 enters the slot 546 again to limit the connecting seat 53.

[0041] The first test is carried out when the No. 1 connecting pipe 532 is directly below. At this time, the staff clamps the samples in sequence on the clamping mechanism 6 connected below the No. 1 connecting pipe 532. As the cylinder 4 drives the T-shaped seat 51 and the mounting rod 52 to descend, the clamping mechanism 6 on the No. 1 connecting pipe 532 and the sample on the clamping mechanism 6 descend synchronously with the mounting rod 52 until they are completely immersed in the clean water in the transparent container 31.

[0042] The purpose of setting two clamping assemblies 64 on the same connecting seat 53 here is that: when the clamping assembly 64 on the No. 1 connecting tube 532 is contaminated by the sample, after the transparent container 31 is cleaned, the clamping mechanism 6 on the No. 2 connecting tube 532 can be switched to the bottom to clamp the test sample, so as to complete the next test without interrupting the test, thereby improving the test efficiency.

[0043] See also Figure 5The clamping mechanism 6 located in the lower connecting tube 532 includes a connecting rod 61, a threaded seat 62, a mounting seat 63 and a clamping assembly 64. The connecting rod 61 is fixedly inserted in the connecting tube 532. The lower end of the connecting rod 61 is threadedly connected to the threaded seat 62. The lower end of the threaded seat 62 is fixedly connected to the mounting seat 63. The mounting seat 63 is a cylindrical block with twelve slots evenly opened on the upper end surface along the circumferential direction, and the clamping assemblies 64 are connected to two symmetrical slots.

[0044] See also Figure 5 The clamping assembly 64 includes a folding rod 641, a connecting head 642, a rectangular connecting ring 643 and a wide-mouth clamp 644. The inclined section of the folding rod 641 is slidably fitted in the slot. The lower end of the vertical section of the folding rod 641 is fixedly connected to the connecting head 642. The side wall of the connecting head 642 is rotatably connected to the rectangular connecting ring 643. The wide-mouth clamp 644 is fixedly connected to the horizontal section below the rectangular connecting ring 643. The structure of the clamping mechanism 6 located in the front connecting tube 532 is the same as that of the clamping mechanism 6 located in the lower connecting tube 532.

[0045] During specific operation, two wide-mouth clamps 644 are used to fix and clamp the non-sealed parts at both ends of the sample, so that the sample is immersed in clean water in a horizontal state during testing to prevent the sample from being incompletely immersed due to excessive buoyancy. The purpose of setting twelve slots on the mounting seat 63 is to facilitate the insertion of folding rods 641 thereon, and then to facilitate the addition of wide-mouth clamps 644, so as to increase its scope of application, so as to facilitate the clamping of some special-shaped packaging samples (such as triangular packaging bags). At the same time, due to the rotational connection between the rectangular connecting ring 643 and the connecting head 642, the wide-mouth clamp 644 can have a certain degree of swing space in the longitudinal direction, so that samples of different sizes can be clamped, further improving its scope of application.

[0046] See also Figure 6 The cleaning mechanism 7 includes a short connecting rod 71, a rotating assembly 72, a pressing tube 73 and a cleaning sponge 74. The short connecting rod 71 is fixedly inserted in the rear connecting tube 532. The upper end of the short connecting rod 71 is connected to the pressing tube 73 through the rotating assembly 72. The upper end of the pressing tube 73 is threadedly connected to a cleaning sponge 74 that matches the transparent container 31.

[0047] See also Figure 6 and Figure 7The rotating assembly 72 includes a circular plate 721, a spiral bar 722, a rotary seat 723 and a reset module 724. The circular plate 721 is fixedly connected to the upper end of the short connecting rod 71. The center of the upper end surface of the circular plate 721 is fixedly connected with a spiral bar 722. The upper end of the spiral bar 722 is cooperatively connected with a rotary seat 723. The rotary seat 723 is fixedly connected in the pressure tube 73. The circular plate 721 and the mortgage tube are connected through the reset module 724.

[0048] See also Figure 6 and Figure 7 The reset module 724 includes an annular plate 7241 and a reset spring 7242. The annular plates 7241 are grouped into two with the same axis. The two annular plates 7241 are rotatably sleeved on the outside of the circular plate 721 and the pressure tube 73 respectively, and the two annular plates 7241 are connected by the reset spring 7242.

[0049] During specific operation, when a certain part of the transparent container 31 is contaminated, the connecting seat 53 is adjusted so that the No. 3 connecting pipe 532 is directly below. Then, as the test proceeds, the mounting rod 52 descends, driving the cleaning sponge 74 to synchronously descend into the contaminated transparent container 31 to wipe off the oil stains on the inner wall of the transparent container 31. When the cleaning sponge 74 reaches the bottom of the transparent container 31, it stops descending due to obstruction. The bottom of the spiral strip 722 is now located in the water outlet pipe 32. Because there is no obstruction, the mounting rod 52 continues to descend, and relative movement occurs between the spiral strip 722 and the cleaning sponge 74, which then drives the pressing tube 73 and the cleaning sponge 74 to rotate synchronously through the rotating seat 723, thereby further cleaning the inner wall of the transparent container 31. During this process, the reset spring 7242 is compressed.

[0050] When the test is completed, as the mounting rod 52 rises, the reset spring 7242 begins to reset due to the loss of the pressure below, and drives the spiral strip 722 and the cleaning sponge 74 to move relative to each other again, and finally reset to the original state. After cleaning is completed, since the cleaning sponge 74 and the pressure tube 73 are connected by threads, the cleaning sponge 74 can be removed and cleaned at any time.
