Abstract

Technical Field
[0001] The present application relates to the technical field of vegetable cleaning, and in particular to a frozen vegetable processing and cleaning machine. Background Art
[0002] In order to extend the shelf life of vegetables, some off-season vegetables may be frozen. Before freezing, they are generally required to be cleaned in order to remove bacteria and pathogens attached to the surface. Among them, the bubble cleaning machine is a common vegetable cleaning equipment. It uses a large number of bubbles generated by high-pressure water flow and a bubble generating device to strongly impact the surface of vegetables. The energy generated by the bursting of bubbles when in contact with the material impacts and scrubs the vegetables, thereby removing dirt and pesticide residues on the surface of the vegetables.
[0003] However, for some vegetables with more air chambers or lighter tissue structures, such as spinach, water spinach and other vegetables, they are easy to float on the water surface when entering the bubble cleaning machine and cannot be completely immersed under the water surface, which can easily lead to poor cleaning effect. In addition, when the high-pressure nozzle on the bubble cleaning machine sprays onto the surface of the vegetables, the surface of the vegetable leaves may be broken due to the water pressure, which makes it easier for microorganisms to invade and the vegetables are more likely to deteriorate. At the same time, the broken leaves are likely to lose some water, resulting in excessive water loss. When they are frozen later, the ice crystals formed become larger, which may cause tissue damage and deterioration of texture, affecting the quality and shelf life of the vegetables. For this reason, we propose a frozen vegetable processing and cleaning machine to solve the above-mentioned problems. Utility Model Content
[0004] In order to avoid the problem that vegetables float on the water surface, resulting in incomplete cleaning, and vegetable leaves are easily bruised by high-pressure water flow, which affects the quality of vegetables, the present application provides a frozen vegetable processing and cleaning machine.
[0005] The above technical objectives of this application are achieved through the following technical solutions:
[0006] A frozen vegetable processing and cleaning machine comprises a cleaning box, wherein a mesh chain conveyor belt for conveying vegetables is arranged inside the cleaning box, a high-pressure nozzle is arranged above the cleaning box, and a bubble generating device for generating bubbles is arranged inside the cleaning box, and further comprises a pressing net, a splash shield with an open bottom, and a buffer member, wherein the pressing net is fixedly connected to the inside of the cleaning box and is used to press the vegetables and immerse them below the water surface inside the cleaning box, the splash shield is connected between the high-pressure nozzle and the pressing net, and the buffer member is movably connected to the bottom of the splash shield and is used to buffer the high-pressure water flow output by the high-pressure nozzle.
[0007] By adopting the above technical solution, the vegetables can be confined under the water surface by a pressure net, so that the vegetables can be fully immersed in water, and the cleaning effect is better. At the same time, the buffer part can be used to buffer the high-pressure water flow output by the high-pressure nozzle to reduce the impact force of the water flow, thereby reducing the impact damage to the vegetable leaves.
[0008] Optionally, a dispersion plate is provided on the outer wall of the buffer, and a plurality of dispersion grooves are formed on the dispersion plate.
[0009] By adopting the above technical solution, it is convenient to disperse the high-pressure water flow, so that the vegetable leaves are impacted by the water flow more evenly, thereby reducing the phenomenon of vegetable leaves being crushed.
[0010] Optionally, a vertical slide groove is provided on the inner wall of the splash shield, a connecting rod is slidably connected inside the vertical slide groove, and the other end of the connecting rod is connected to the buffer component.
[0011] By adopting the above technical solution, the movement trajectory of the buffer component can be limited so that it can only move up and down in the splash shield to avoid affecting the movement direction of the water flow.
[0012] Optionally, a drainage portion is provided at the upper end of the buffer member, and the drainage portion is in the shape of a cone with the tip facing upward.
[0013] By adopting the above technical solution, high-pressure water can be better led out from the output end of the splash shield, avoiding a large contact area between the end of the buffer and the water flow, which affects the passage of the water flow.
[0014] Optionally, a material guiding portion is provided at the bottom end of the buffer member, and the material guiding portion is arranged to be gradually inclined downward from the conveying direction of the mesh chain conveyor belt.
[0015] By adopting the above technical solution, when vegetables pass under the buffer, they come into contact with the inclined material guiding portion, thereby preventing the buffer from blocking the movement of the vegetables.
[0016] Optionally, a rounded corner is provided at the bottom end of the material introducing portion.
[0017] By adopting the above technical solution, the rounded corners can prevent the edge of the bottom of the material guide part from coming into contact with the vegetable leaves, thereby preventing damage to the vegetables.
[0018] Optionally, the diameter of the splash shield gradually increases from top to bottom.
[0019] By adopting the above technical solution, it is possible to better adapt to the divergent state of the water flow and reduce the impact of the water flow on the splash guard.
[0020] Optionally, both ends of the pressing net are integrally formed with a material stopper which is obliquely provided, and the position of the material stopper is higher than the position of the pressing net.
[0021] By adopting the above technical solution, vegetables can be easily put into the space between the pressing net and the net chain conveyor belt, thus preventing vegetables from falling onto the pressing net.
[0022] By setting a pressing net, the vegetables can be pressed and immersed below the water surface in the cleaning box to prevent the vegetables from floating, so that the vegetables can fully contact with water and improve the cleaning effect;
[0023] By providing a buffer and a dispersion plate located outside the buffer, the high-pressure water flow sprayed from the high-pressure nozzle is dispersed, so that the water flow impact on the vegetable leaves is more uniform and the water flow pressure is reduced, avoiding the water flow from directly contacting the vegetables to prevent the vegetable leaves from being crushed.

[0031] The present application is further described in detail below in conjunction with the accompanying drawings.
[0032] The embodiment of the present application discloses a frozen vegetable processing and cleaning machine, comprising a cleaning box 1, wherein a mesh chain conveyor belt 11 for conveying vegetables is provided inside the cleaning box 1, a high-pressure nozzle 12 is provided above the cleaning box 1, the high-pressure nozzle 12 can be arranged equidistantly inside the cleaning box 1, and a bubble generating device 13 for generating bubbles is provided inside the cleaning box 1, the bubbles generated by the bubble generating device 13 continue to grow in the process of rising, and when they reach the water surface, they will quickly burst, generating an instantaneous impact force, which can peel off dirt and impurities on the surface of vegetables and wash them away, and the high-pressure nozzle 12 is connected to an external water supply device, and the vegetables in the cleaning box 1 are cleaned with high-pressure water flow, which is coordinated with bubble cleaning to improve the cleaning effect, and the vegetables are conveyed by the mesh chain conveyor belt 11, and this technology is a prior art, and those skilled in the art should be aware that , I will not go into details here. When the bubble cleaning machine is actually used, some lighter vegetables may float above the water surface and cannot be fully immersed in the water. The utility model arranges a pressing net 2 inside the cleaning box 1 to press the vegetables and immerse them below the water surface inside the cleaning box 1, so that the vegetables are fully in contact with water for cleaning. In order to avoid splashing caused by the contact of the water flow sprayed by the high-pressure nozzle 12 with the pressing net 2, a splash shield 3 with an open bottom is connected between the high-pressure nozzle 12 and the pressing net 2 to protect the high-pressure water flow sprayed by the high-pressure nozzle 12, and the water flow is introduced to the bottom of the pressing net 2 to rinse the vegetables, which also avoids splashing of the water flow. The splash shield 3 is movably connected with a buffer 4 inside to buffer the high-pressure water flow output by the high-pressure nozzle 12, so as to avoid the high-pressure water flow being directly sprayed onto the surface of the vegetables to cause damage to the leaves of the vegetables and affect the quality of the vegetables.
[0033] Furthermore, a dispersion plate 41 is provided on the outer wall of the buffer member 4, and a plurality of dispersion grooves 42 are opened on the dispersion plate 41. After the high-pressure water flow passes through the dispersion grooves 42 on the dispersion plate 41, the high-pressure water flow will be dispersed, so that the water flow is transformed into multiple smaller water flows, so that the impact of the water flow on the vegetable leaves will be more uniform, thereby reducing the phenomenon of the vegetable leaves being crushed.
[0034] Furthermore, a drainage portion 6 is provided at the upper end of the buffer 4. The drainage portion 6 is a cone with the tip facing upward, which can avoid the contact area between the upper end of the buffer 4 and the high-pressure water flow, thereby reducing the obstruction of the buffer 4 to the water flow, so that the water flow can fall on the dispersion plate 41 to a greater extent for dispersion.
[0035] Furthermore, a vertical slide groove 5 is provided on the inner wall of the splash shield 3, and a connecting rod 51 is slidably connected inside the vertical slide groove 5. The other end of the connecting rod 51 is connected to the buffer 4, and the buffer 4 is limited by the sliding of the connecting rod 51 in the vertical slide groove 5, so that the buffer 4 can only move vertically up and down. At the same time, when the high-pressure water flow produces a downward impact force on the buffer 4, the buffer 4 overcomes the resistance of the water, and its bottom end moves to the bottom of the pressing net 2, which can press the vegetables under the pressing net 2 downward, and when the vegetables are out of contact with the buffer 4, the vegetables will float to the bottom of the pressing net 2, so that the movement trajectory of the vegetables can be in a peak-and-valley state, so that the movement amplitude of the vegetables is larger, the contact area with water is increased more comprehensively, and the cleaning effect is improved.
[0036] Furthermore, a guide portion 7 is provided at the bottom end of the buffer member 4, and the guide portion 7 is inclined gradually downward from the conveying direction of the mesh chain conveyor belt 11. When the mesh chain conveyor belt 11 drives the vegetables to move, the vegetables contact the inclined guide portion 7 to avoid the buffer member 4 from intercepting the vegetables and affecting the passage of the vegetables, and a rounded portion 8 is provided at the bottom end of the guide portion 7. When the vegetables pass through the guide portion 7, the arc-shaped rounded portion 8 can be used to avoid the bottom edge of the guide portion 7 from causing damage to the vegetables, thereby improving the quality of the vegetables.
[0037] Furthermore, as the water sprayed from the high-pressure nozzle 12 flows downward, the pressure will gradually decrease, causing the speed and impact force of the water flow to weaken accordingly, and the water flow will gradually diffuse and increase in diameter. Therefore, the diameter of the splash guard 3 gradually increases from top to bottom, which can better adapt to the divergent state of the water flow and reduce the impact of the water flow on the splash guard 3.
[0038] Furthermore, both ends of the pressing net 2 are integrally formed with a material blocking portion 9 which is inclined and the position of the material blocking portion 9 is higher than the position of the pressing net 2. When vegetables are placed at the input end of the mesh chain conveyor 11 and the washed vegetables are output at the output end, the vegetables on the mesh chain conveyor 11 can be prevented from falling onto the pressing net 2.
[0039] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
