Description

Technical Field

[0001] The utility model relates to the technical field of food processing, in particular to a high-efficiency bamboo shoot desalination and desulfurization device. Background Art

[0002] Nanchuan square bamboo shoots are one of the main production areas of square bamboo shoots in my country. They grow on the high mountains of Jinfo Mountain in Nanchuan. Because square bamboo shoots grow in high mountain jungles, they are of pure quality, square in shape, thick and delicious. In addition, they are produced in autumn, which forms a seasonal contrast with most bamboo shoots that are on the market in spring, and have obvious market advantages.

[0003] Fresh bamboo shoots are perishable and difficult to store. Currently, they are often preserved with sodium metabisulfite and salt to create fresh bamboo shoots. Before consumption, they must be desulfurized and desalinated, with residual sulfur dioxide levels reduced to below 100 ppm. While fresh bamboo shoots are free of microorganisms, they are susceptible to microbial contamination during the desulfurization process. Prepackaged bamboo shoots made from these contaminated products are prone to rotting and browning, causing significant losses to businesses.

[0004] According to research, bamboo shoot production companies currently use air pumps for desulfurization in open environments. These desulfurization containers are typically 1-3 ton plastic barrels. These barrels, exposed to the corrosion of sulfur dioxide over time, form large quantities of microplastic particles, which pose a health hazard. Furthermore, for ease of operation, the barrels are typically 0.8-1 meter tall, occupying a significant amount of space. This significantly restricts the company's expansion as production scales.

[0005] CN221011887U discloses a desulfurization device for processing bamboo shoots, comprising a soaking frame, wherein support frames and a connecting top plate are symmetrically fixedly mounted on the left and right sides of the outer wall of the soaking frame, and electric telescopic rods and sliding pressure plates are fixedly mounted at the four corners of the front, back, left and right sides of the lower end of the outer wall of the connecting top plate. The sliding pressure plates are used to repeatedly squeeze the bamboo shoots soaked in the frame to desulfurize them. However, since bamboo shoots are cut into various forms such as slices, shreds, or intact tips during the production process, this processing method is not suitable for those that need to retain intact cylindrical tips. At the same time, the water resistance is large, the energy consumption is high, and the efficiency is low. Utility Model Content

[0006] The utility model aims to solve the technical problems existing in the prior art, and particularly innovatively proposes a high-efficiency bamboo shoot desalination and desulfurization device, which can stably desulfurize and desalinate bamboo shoots.

[0007] In order to achieve the above-mentioned object, the utility model provides a high-efficiency bamboo shoot desalination and desulfurization device, comprising a closed tank body, a feed hopper and a water inlet are provided on the top of the tank body, a drain outlet is provided on the bottom of the tank body, a discharge port and a sampling port are provided on the middle of the right side wall of the tank body, a discharge door and a chute are provided at the discharge port, and the tank body is also equipped with an ozone generator;

[0008] The tank body is provided with a lifting steel plate for scooping up materials, and the tank body is equipped with a self-priming pump. The water inlet pipe and the return pipe of the self-priming pump are respectively connected to the water outlet at the bottom of the tank body and the return water port at the top, and the return water port is located above the lifting steel plate;

[0009] The lifting steel plate is L-shaped, including a vertical plate and a horizontal plate. The vertical plate is arranged away from the discharge port, the horizontal plate matches the inside of the tank body, and there are leakage holes distributed on the horizontal plate. Cables are provided on the left and right ends of the horizontal plate. Motors are provided on the top of the tank body for pulling the cables on the left and right sides respectively. A discharge limiting structure is provided in the tank body, and the discharge limiting structure is used to limit the right end of the horizontal plate to be flush with the discharge port, so that the left end of the horizontal plate can continue to move upward, thereby dumping the material.

[0010] In the above solution, the bottom of the inner side of the tank is provided with a column, and the lifting steel plate is placed on the column, so that there is a gap between the lifting steel plate and the bottom of the tank. The water outlet is located below the lifting steel plate. This ensures that the material at the bottom can be repeatedly washed, desalination and desulfurization are carried out, and the desalination and desulfurization efficiency is improved.

[0011] In the above scheme: the discharging limiting structure includes a pair of push rods, the bottom ends of the push rods are provided with push forks that are always clamped with the transverse plate, the transverse plate is provided with through holes corresponding to the top forks, and the through holes are provided with rotating shafts extending forward and backward, and the rotating shafts are used to be supported by the push forks, and a guide sleeve that is connected up and down is provided at the upper part of the tank body, and the push rods are always slidably connected in the guide sleeves.

[0012] In the above solution, the push rod is a telescopic rod equipped with a compression spring. A stop button is located directly above the push rod on the top of the inner side of the tank. This stop button is used to stop the motor of the right-hand cable. When the lifting plate is raised to the same level as the discharge port, the push rod contacts the stop button. When the lifting plate reaches the discharge port, the motor of the right-hand cable set is automatically stopped, allowing the material on the lifting plate to be dumped out as quickly as possible. The telescopic rod reduces the pressure on the stop button, preventing damage caused by excessive force from the left-hand cable motor.

[0013] In the above solution, the guide sleeve is U-shaped and forms a cavity with the side wall of the tank body to restrain the ejector rod. The structure is simple and can ensure that the ejector rod is placed as close to the right as possible, ensuring successful connection between the transverse plate and the chute.

[0014] In the above solution: a transparent cover is provided at one end of the chute close to the tank body for observation.

[0015] In the above solution: the height of the vertical plate is one-third of the height of the tank body, and the return pipe of the self-priming pump is arranged at two-thirds of the height of the tank body.

[0016] In the above solution: a cleaning nozzle is provided on the top of the inner side of the tank body, which can clean the inside of the tank body.

[0017] In summary, the beneficial effects of the present invention are as follows: the provided tank body can avoid light desalination and desulfurization, and ensure that the bamboo shoots do not fade during the desalination and desulfurization process. The provided self-priming pump can drive the liquid to flow, improve work efficiency, and at the same time form a sealed connection through the water inlet pipe and the return pipe to avoid contact with the external air to cause secondary microbial contamination, and the desalination and desulfurization efficiency is high. The material is placed on the lifting steel plate, which can minimize the turning and pressing of the material, reduce the force on the material, avoid the material from breaking, and ensure production quality. The provided lifting steel plate can lift the material out of the liquid, and by only stopping the motor on the right side, the left side of the lifting steel plate continues to lift, forming an inclined state, so as to discharge the material. The provided vertical plate can prevent the material from falling out of the gap between the left end of the horizontal plate and the tank body during the tilting process.

[0022] The present invention will be further described below with reference to the following embodiments and accompanying drawings:

[0023] like Figures 1 to 4 A highly efficient bamboo shoot desalination and desulfurization device is shown, comprising a tank body 1 made of 304 stainless steel. In this embodiment, the tank body 1 is rectangular. A feed hopper 1a and a water inlet 1f are located near the top of the tank body 1, while a drain outlet 1b is located near the bottom. A discharge port and a sampling port 1c are located near the center of the right side wall of the tank body 1. A sampling tap can be installed on the sampling port to facilitate the release of water from the tank body 1 for sulfur content testing, improving detection efficiency.

[0024] The discharge port is equipped with a discharge door and a chute 1d. The discharge door can close the discharge port to prevent the ingress of foreign matter. The chute 1d improves discharge efficiency. A transparent cover 5 is installed at the end of the chute 1d near the tank body 1 to allow for observation. The tank body 1 is also equipped with an ozone generator 3, which can be used for disinfection.

[0025] A cleaning nozzle 4 is provided at the top of the inner side of the tank body 1, which can clean the inside of the tank body 1. A lifting steel plate 7 for scooping up materials is provided inside the tank body 1, and the tank body 1 is equipped with a self-priming pump 6. The water inlet pipe and the return pipe of the self-priming pump 6 are respectively connected to the water outlet at the bottom of the tank body 1 and the return water port at the top, and the return water port is located above the lifting steel plate 7. The self-priming pump 6 can be used for repeated flushing to improve the desalination and desulfurization efficiency and to mix the water evenly. A column 1e is provided at the bottom of the inner side of the tank body 1, and the lifting steel plate 7 is placed on the column 1e, so that there is a distance between the lifting steel plate 7 and the bottom of the tank body 1. The water inlet pipe of the self-priming pump 6 is provided below the lifting steel plate 7 to ensure that the materials at the bottom can also be repeatedly flushed.

[0026] Specifically, the lifting steel plate 7 is L-shaped and includes a vertical plate 7a and a horizontal plate 7b. The vertical plate 7a is set away from the discharge port and its height is one-third of the height of the tank body 1. The return pipe of the self-priming pump 6 is set at two-thirds of the height of the tank body 1.

[0027] The transverse plate 7b fits inside the tank 1 and is equipped with drainage holes. A pair of cables are installed on each end of the transverse plate 7b. A motor 2 is installed at the top of the tank 1, corresponding to each cable, to pull the left and right cables. The motors 2 are forward and reverse rotating and are equipped with a main switch and two switches for switching the rotation direction. The two switches control the two hoist motors on the left and right, respectively.

[0028] A discharge limiting structure 8 is provided in the tank body 1 near the discharge port, and the discharge limiting structure 8 is used to limit the right end of the transverse plate 7b to be flush with the discharge port, so that the left end of the transverse plate 7b can continue to move upward, thereby dumping the material.

[0029] The discharge limiting structure 8 comprises a pair of telescopic push rods, each consisting of a rod body and a telescopic sleeve. The sleeve is closed at the top and open at the bottom, with the top of the rod body always positioned within the sleeve. A compression spring 8b is also installed on the top of the rod body. A stop button 9 is located directly above the push rods on the top of the inner side of the tank body 1. This button is waterproof and automatically stops the motor 2 of the right-hand pull cable, thereby quickly discharging the material from the lifting steel plate 7.

[0030] The bottom end of the rod body is provided with a top fork 8a that is always engaged with the transverse plate 7b, and a through hole is provided on the transverse plate 7b corresponding to the top fork 8a. A rotating shaft extending forward and backward is provided in the through hole, and the rotating shaft is used to be supported by the top fork 8a. A guide sleeve 8c that is connected to each other from top to bottom is provided at the upper part of the tank body 1, and the top rod is always slidably connected in the guide sleeve 8c. The bottom end of the guide sleeve 8c is higher than the bottom end of the discharge port, and the guide sleeve 8c is U-shaped, and forms a cavity with the side wall of the tank body 1 to limit the top rod. The structure is simple, and can ensure that the top rod is set as close to the right as possible to ensure that the transverse plate 7b is successfully connected to the chute. It is set as a top fork 8a, and the top rod and the lifting steel plate 7 can be disassembled for easy maintenance and replacement.

[0031] During use, first put the material from the feed hopper 1a into the tank body 1, and transfer the desalted and desulfurized liquid from the water inlet to the tank body 1. Start the self-priming pump 6 to pump the liquid at the bottom to the lifting steel plate 7 for repeated desalination and desulfurization to ensure sufficient contact between the liquid and the material and improve the desalination and desulfurization efficiency. After desalination and desulfurization are completed, start the motor 2 to drive the lifting steel plate 7 to move upward. When the lifting steel plate 7 moves to the same level as the outlet, the top rod just hits the stop button 9, thereby stopping the motor 2 of the right cable. The motor 2 of the left cable still drives the lifting steel plate 7 to move upward, and under the action of the top fork 8a and the rotating shaft 7d, the lifting steel plate 7 is rotated, thereby pouring the material from the lifting steel plate 7 for discharging.

[0032] After the processing is completed, the tank body 1 can be cleaned by cleaning the nozzle 4 to improve hygiene and avoid bacterial growth.
