Description

Technical Field

[0001] This invention belongs to the field of pickled vegetable preparation technology, and in particular relates to a low-oil pickled vegetable preparation device based on vacuum aroma infusion technology. Background Technology

[0002] Pickled vegetables, a traditional Chinese condiment, are commonly processed using a vacuum tumbling and flavor-permeating process to enhance their flavor and extend their shelf life. The vacuum tumbling machine creates a negative pressure environment within a sealed drum, and combined with the rotation of the drum or shaft, causes the pickled vegetables to tumble and knead inside, promoting the penetration of the seasoning liquid. It is also one of the core pieces of equipment in the preparation of low-oil pickled vegetables.

[0003] For example, Chinese patent document (CN213215091U) discloses a vacuum tumbling machine, including: a tumbling drum, a vacuum pump, a support mechanism disposed below the tumbling drum, and a cleaning mechanism and a tumbling mechanism disposed inside the tumbling drum; the vacuum pump is disposed below the support mechanism and is equipped with a vacuum suction tube, the other end of which is connected to the interior of the tumbling drum; the tumbling mechanism includes a rotating shaft disposed inside the tumbling drum, a tumbling blade assembly spirally disposed on the rotating shaft, and the tumbling blade assembly being movably connected to the rotating shaft; it also includes multiple protrusions evenly distributed on the inner wall of the tumbling drum; the rotating shaft is vacuum-sealed; it also includes a drive motor disposed on the support mechanism, the drive motor being used to drive the rotating shaft to rotate; the cleaning mechanism includes a water tank communicating with the interior of the rotating shaft, and nozzles evenly distributed on the rotating shaft; the nozzles are used to spray water to clean the interior of the tumbling drum.

[0004] However, the above solution has the following drawbacks because the protrusions on the cylinder wall are fixed structures that can only be adapted to pickles of specific shapes and sizes: when preparing pickles of different specifications, it is impossible to adjust the turbulence effect of the cylinder wall according to the turning and mixing requirements of different materials such as shredded, flake, or block, making it difficult to meet the flexible production needs of the current pickle industry for multiple specifications and categories.

[0059] Please see Figures 1-6 It also includes:

[0060] The centers of the inner cylinder 302 and the outer cylinder 301 are on the same axis. The inner cylinder 302 and the outer cylinder 301 are connected to the same feed port on one side. The inner cylinder 302 and the outer cylinder 301 are provided with a circular through hole on the side away from the feed port. The circular through hole is located on the side close to the lifting support platform 2.

[0061] The inner cylinder 302 has a plurality of sliding through holes 303 arranged in a circumferential array inside, and a plurality of protrusions 304 are provided between the plurality of sliding through holes 303. The protrusions 304 are provided on the inner wall of the inner cylinder 302.

[0062] Multiple sealing units 6 are respectively disposed inside multiple sliding through holes 303, and the exterior of the sealing unit 6 is fixedly connected to the inner wall of the inner cylinder 302. The sealing unit 6 is slidably sealed on the exterior of the rib 706. The cross-sectional shape of the sealing unit 6 is set as rectangular. The sealing unit 6 is integrally formed from a sealing lip, an elastic support and a wear-resistant liner. The sealing lip is made of food-grade silicone rubber.

[0063] The drive unit 4 includes a hollow shaft 401, which is rotatably connected inside the lifting support platform 2. One end of the hollow shaft 401 extends to the outside of the lifting support platform 2 and communicates with the outer cylinder 301. A first gear 402 is fixedly connected to the outside of the hollow shaft 401. A second gear 403 is meshed with one side of the first gear 402. A rotating shaft 404 is fixedly connected inside the second gear 403. The rotating shaft 404 is rotatably connected inside the lifting support platform 2. One end of the rotating shaft 404 extends to the outside of the lifting support platform 2 and is fixedly connected to a first drive motor 405. The first drive motor 405 is fixedly connected to the outer wall of the lifting support platform 2 through a motor mounting seat, and the first drive motor 405 is located on the side away from the outer cylinder 301.

[0064] The lifting support platform 2 is hinged to a support frame 1 on the side away from the drive unit 4. A lifting drive unit is symmetrically arranged on one side inside the support frame 1, and the other end of the lifting drive unit is fixedly connected to one side of the bottom of the lifting support platform 2.

[0065] The specific usage method and working principle are as follows: First, install the external hydraulic flip-top unit on the lifting support platform 2, and install the external hydraulic flip-top unit on the side close to the feed inlet. The desalted and drained shredded pickled vegetables are conveyed to the inner cylinder 302 through the feed inlet by the external conveying device. Then, the external hydraulic flip-top unit seals the feed inlet.

[0066] After the sealing is completed, the external air extraction device is connected to the air extraction pipe on the external hydraulic flip-top unit to extract the air from the inner cylinder 302, making it a vacuum negative pressure state. Then, the first drive motor 405 is started. The first drive motor 405 will drive the second gear 403 to rotate through the rotating shaft 404. Utilizing the linkage effect between the second gear 403 and the first gear 402, the power is transmitted to the first gear 402. The first gear 402 drives the outer cylinder 301, inner cylinder 302, annular sleeve 5 and auxiliary preparation component 7 to rotate synchronously through the hollow shaft 401. During the rotation, the inner cylinder 302 will throw up and mix the shredded pickles inside. The lifting support platform 2 will support the preparation cylinder 3 during the rotation.

[0067] When the external conveying device delivers the desalted and drained sheet pickles into the inner cylinder 302 through the feed inlet, the second drive motor 707 is activated. The second drive motor 707 drives the third gear 703 to rotate through a lead screw 704. The third gear 703 drives all other ring gears 702 and the lead screw 704 to rotate simultaneously through the ring gear 702. Utilizing the linkage effect between the lead screw 704 and the lead screw sleeve 705, the power is transmitted to the lead screw sleeve 705. Under the restriction of the rectangular through hole, the lead screw sleeve 705 can only drive the rib 706 to move inward toward the inner cylinder 302, increasing the height of the inner cylinder 302 and its inner wall. This improves the mixing effect of the inner cylinder 302 on the sheet pickles, eliminates the dead corners of the stacked sheet pickles, and provides uniform contact conditions for subsequent aroma infusion. During this process, the sealing unit 6 improves the sealing performance between the rib 706 and the inner cylinder 302 during the adjustment process.

[0068] When the external conveying device transports the desalted and drained block pickled vegetables into the inner cylinder 302 through the feed inlet, the second drive motor 707 is started again. The second drive motor 707 continues to drive the lead screw 704 to rotate, and the lead screw sleeve 705 will continue to drive the rib 706 to move into the inner cylinder 302, which improves the mixing effect of the block pickled vegetables, breaks the stacked and compacted state of the block pickled vegetables, avoids the formation of an airtight layer inside, and thus improves the device's ability to prepare pickled vegetables of different specifications.

[0069] Please see Figure 3 , Figures 7-10 The inner cylinder 302 is equipped with a spray assembly 8, which includes:

[0070] A spray pipe 801 passes through the hollow shaft 401 and is rotatably connected to the circular through hole via a bearing. The centers of the spray pipe 801 and the hollow shaft 401 are on the same axis. The end of the spray pipe 801 away from the inner cylinder 302 is fixedly connected to the inside of the lifting support platform 2. The end of the spray pipe 801 away from the inner cylinder 302 extends to the outside of the lifting support platform 2. Multiple sets of nozzles 807 are equidistantly arranged inside the spray pipe 801 along its length. Each set of nozzles 807 consists of multiple nozzles 807. The multiple nozzles 807 are arranged in a circumferential array inside the spray pipe 801. A swirl groove 808 is opened at the end of the nozzle 807 away from the spray pipe 801. The end of the nozzle 807 away from the spray pipe 801 is set to a cone shape.

[0071] The cylinder 803 is located on the side near the lifting support platform 2, and both ends of the cylinder 803 are fixedly connected to the inside of the spray pipe 801 through the first mounting bracket 802. The centers of the spray pipe 801 and the cylinder 803 are on the same axis.

[0072] An electric push rod 804 is fixedly connected to one side of the inside of the cylinder 803. The electric push rod 804 is located near the lifting support platform 2. One end of the output shaft of the electric push rod 804 extends to the outside of the cylinder 803 and is fixedly connected to a roller 805. The output shaft of the electric push rod 804 is slidably sealed inside the cylinder 803. The roller 805 is composed of multiple large cylinders, multiple truncated cones, and multiple small cylinders that are alternately spliced ​​together. A limiting groove is opened at the end of the roller 805 away from the electric push rod 804. A limiting slider is slidably connected inside the limiting groove. The side of the limiting slider away from the roller 805 is fixedly connected to the inner wall of the spray pipe 801.

[0073] The roller 805 has multiple small cylindrical sections with a circumferential array of rollers 806. A connecting rod 813 is fixedly connected to the side of each roller 806 away from the roller 805. The end of the connecting rod 813 away from the roller 806 extends into the nozzle 807 and is fixedly connected to a conical valve core 814. The side of the conical valve core 814 away from the connecting rod 813 is conical, and the conical surface of the conical valve core 814 matches the inner conical surface of the nozzle 807. An installation cylinder 810 is provided between the conical valve core 814 and the roller 806. The installation cylinder 810 is slidably sealed to the outside of the connecting rod 813, and a second mounting bracket 809 is fixedly connected to the outer side of the installation cylinder 810. The second mounting bracket 809 is located near the roller 806, and the outer end of the second mounting bracket 809 is fixedly connected to the inner wall of the nozzle 807.

[0074] A spring 811 is fixedly connected to the top surface of the mounting cylinder 810. The spring 811 is sleeved on the outer periphery of the connecting rod 813. An annular plate 812 is fixedly connected to the bottom surface of the spring 811. The annular plate 812 is fixedly connected to the outside of the connecting rod 813 and is slidably connected inside the mounting cylinder 810.

[0075] The specific usage method and working principle are as follows: During the rotation of the preparation cylinder 3 and the pickled vegetables driven by the drive unit 4, the spray pipe 801 remains fixed inside the preparation cylinder 3. At this time, the external liquid is transported to the inside of multiple nozzles 807 through the spray pipe 801. After the liquid enters the large cavity inside the nozzle 807, it expands and depressurizes. The flowing liquid will collide with the inner wall of the nozzle 807 to generate turbulent flow. Then, with the forced swirling of the swirl channel 808, the turbulence and swirling flow couple to shear and tear the liquid, breaking the liquid phase medium into micron-sized fine droplets, forming low-pressure diffuse atomized droplets, and spraying them onto the surface of the continuously thrown and mixed shredded pickled vegetables. Under the synergistic effect of the vacuum negative pressure of the inner cylinder 302, the atomized droplets quickly penetrate into the micropores of the shredded pickled vegetable tissue, achieving low-oil and uniform aroma infiltration, while avoiding the high-speed jet from dispersing and breaking the shredded material, thus improving the uniformity of aroma infiltration and the integrity of the finished product.

[0076] When the external conveying device delivers the desalted and drained sheet pickles into the inner cylinder 302 through the inlet, the electric push rod 804 is activated. The output shaft of the electric push rod 804 drives the roller 805 to move towards the limiting slider inside the spray pipe 801. The limiting slider and the limiting groove inside the roller 805 improve the stability of the roller 805 during the translation process. During the smooth movement of the roller 805, the roller 806 will move to the middle position of the truncated cone. At this time, the roller 806 will move through the connecting... The connecting rod 813 drives the annular plate 812 to compress the spring 811. At the same time, the connecting rod 813 will drive the conical valve core 814 to move towards the conical surface of the inner wall of the nozzle 807, so that the liquid is transported to the vortex tank 808 through the medium flow channel gap formed by the conical valve core 814 and the inner wall of the nozzle 807. The vortex tank 808 will cause the liquid to swirl slightly, and the liquid will be sprayed out in the form of an umbrella-shaped wide-angle spray, which will increase the spray coverage area of ​​the sliced ​​pickles and improve the mixing coverage and flavor uniformity of the device for the sliced ​​pickles.

[0077] When the external conveying device transports the desalted and drained block pickles into the inner cylinder 302 through the inlet, the electric push rod 804 is activated. The electric push rod 804 continues to squeeze the roller 806 through the roller 805, causing the connecting rod 813 to continue driving the conical valve core 814 to move towards the inner conical surface of the nozzle 807. The gap between the conical valve core 814 and the flow channel inside the nozzle 807 is compressed again, the channel narrows, and the liquid is squeezed and accelerated, so that the liquid is sprayed into the block pickles under high pressure. Combined with the vacuum negative pressure environment of the inner cylinder 302, the penetration efficiency of the low-oil seasoning liquid into the block pickles is improved, making the device suitable for the aroma-penetrating needs of pickles of different specifications.
