Description

Technical Field

[0001] This invention relates to the field of shredding equipment technology, specifically a shredding machine and shredding method for food processing. Background Technology

[0002] A food processing shredder is a specialized piece of machinery used in the food processing industry. Through mechanical structures such as rotating blades, sharp mesh, and reciprocating blades, it applies cutting or extrusion forces to various ingredients, such as root vegetables, leafy vegetables, and bean products, processing them into shredded semi-finished or finished products with uniform cross-section and controllable dimensions to meet the needs of subsequent cooking, packaging, and storage. It is widely used in restaurant kitchens, food processing plants, and supermarket fresh food handling, and must meet food contact material safety standards, possess characteristics such as easy cleaning and adjustable shredding specifications, and be an automated or semi-automated processing equipment.

[0003] Existing Chinese patent document CN222450528U discloses a food shredder, including a worktable with placement slots on both sides of the top of the worktable. A first connecting frame is fixedly installed on the top of the worktable, and an electric push rod is fixedly installed on the inner wall of the first connecting frame. A pressure plate is provided at the output end of the electric push rod. An operator places food into the worktable. A first motor operates, causing the clamping plate to move closer to and limit the food on both sides. The electric push rod then moves the pressure plate downwards to push the food. A second motor moves the shredder left and right to shred the food, reducing the need for manual labor. The machine's operation and time are simplified to improve efficiency. When the operator reduces the limiting force on the outside of the shredder, the spring force pushes the shredder out through the push plate, simplifying operation and enhancing usability. However, this food processing shredder still has shortcomings: it relies on a single shredder for shredding. Adjusting the shredding thickness requires disassembling and replacing shredders of different specifications. The replacement process lacks convenient positioning and fixing structures, making it cumbersome and time-consuming. Furthermore, the replacement shredder's installation position is prone to deviation, leading to decreased shredding accuracy and difficulty in adapting to the diverse shredding requirements of different ingredients. Summary of the Invention

[0004] The purpose of this invention is to address the problem that food processing shredders rely on a single shredder for shredding, and that adjusting the shredding thickness requires disassembling and replacing shredders of different specifications. This replacement process lacks convenient positioning and fixing structures, making it cumbersome, time-consuming, and prone to misalignment of the shredder's installation position after replacement, leading to decreased shredding accuracy and difficulty in adapting to the diverse shredding thickness requirements of different ingredients. Therefore, this invention provides a shredder for food processing.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a shredder for food processing, comprising: a base frame, a middle frame fixedly connected to the top of the base frame, supporting square rods symmetrically fixedly connected to the top surface of the middle frame in four directions, a top frame fixedly connected to the top of the supporting square rods, a frame slot opened on the inner side of the middle section of the middle frame, a dense mesh shredder frame inserted into the frame slot, a first staggered rod plate and a second staggered rod plate slidably connected to the top of the middle frame, a hydraulic lifting column fixedly installed through the center of the top frame, and a water collection box and a drain box connected to the internal slide rail of the base frame.

[0006] As a further embodiment of the present invention: the dense mesh cutting frame is snapped into the slot of the frame and a positioning strip is fixed to the outside. One end of the positioning strip is provided with a rod-through groove. An adjustment groove is provided through one side of the rod-through groove. An L-shaped insert rod is movably inserted into the rod-through groove. A tension spring is fixed to the end face of the L-shaped insert rod. The other end of the tension spring is fixed to the corresponding side inside the rod-through groove.

[0007] As a further embodiment of the present invention: the number of the rod slot, the adjustment slot, the L-shaped insert rod and the tension spring are all provided in two sets, which are symmetrically arranged at both ends of the positioning strip. The inside of the card frame slot is provided with hole and slot structure on both sides that are adapted to the specifications and positions of the end face of the L-shaped insert rod.

[0008] As a further embodiment of the present invention: symmetrical side sliders are fixedly connected to both sides of the staggered rod plate, and sliding connection with the equipment frame is achieved through the side sliders. An adjustment screw hole is opened through the center of the side slider, and a bidirectional screw is screwed through the adjustment screw hole. A holding sleeve is fixedly sleeved on the outer side of the middle section of the bidirectional screw. A screw insertion hole is opened on the side of the support square rod. The bidirectional screw is horizontally arranged between two adjacent sets of support square rods through the screw insertion hole structure, and passes through the adjustment screw holes of two sets of side sliders on the same side.

[0009] As a further embodiment of the present invention: there are two sets of the staggered rod plate one and staggered rod plate two, and each set is a plate structure with several sets of hollow strip holes, and the four are arranged perpendicular to each other. The hollow strip holes in the staggered rod plate one and staggered rod plate two are staggered. The staggered rod plate two is also provided with the same number and specifications of side sliders, adjusting screw holes, bidirectional screws and holding sleeve structures.

[0010] As a further embodiment of the present invention: the moving end of the hydraulic lifting column faces the middle frame of the equipment, and the water collection box and the drain box are both coaxially arranged with the middle frame of the equipment and the hydraulic lifting column.

[0011] As a further embodiment of the present invention: a fixed frame is fixedly connected to one side of the frame in the device, and a feeding conveyor belt module is provided on the top of the fixed frame. The output end of the feeding conveyor belt module is flush with the top surfaces of the first and second staggered plates.

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, the fine mesh shredding frame can be quickly inserted into or detached from the slot without complicated tools through the cooperation of positioning strips, L-shaped inserts and tension springs. Operators can change to fine mesh shredding frames with different mesh sizes according to the required thickness of the shredded ingredients, making it more adaptable. 2. In this invention, the staggered plate one and staggered plate two are connected by a threaded transmission structure of a bidirectional screw and a side slider. The distance between the two sets of staggered plates can be adjusted synchronously by simply rotating the handle sleeve, forming a rectangular feeding channel that matches the original size of the food. The threaded transmission ensures the adjustment accuracy. With the above dual structure, the equipment can simultaneously adapt to different original sizes of food and different cutting thicknesses, taking into account both practicality and operational efficiency. It is especially suitable for the multi-category and multi-specification cutting needs in food processing scenarios. Attached Figure Description

Detailed Implementation

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In the description of this invention, it should be noted that unless otherwise explicitly specified and limited, the terms "installed," "connected," "linked," and "set up" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0017] Reference Figures 1 to 6 In this embodiment of the invention, a shredder for food processing includes: a base frame 1, a middle frame 2 fixedly connected to the top of the base frame 1, support square rods 3 symmetrically fixedly connected to the top surface of the middle frame 2, a top frame 4 fixedly connected to the top of the support square rods 3, a frame slot 5 opened on the inner side of the middle section of the middle frame 2, a dense mesh shredder 6 inserted inside the frame slot 5, a first staggered rod plate 12 and a second staggered rod plate 13 slidably connected to the top of the middle frame 2, a hydraulic lifting column 19 fixedly installed through the center inside the top frame 4, and a water collection box 20 and a drain box 21 connected to the internal slide rail of the base frame 1.

[0018] Reference Figure 4 and Figure 5The mesh cutting frame 6 is snapped into the slot 5 and a positioning strip 7 is fixed to the outside. One end of the positioning strip 7 is provided with a rod groove 8. An adjustment groove 9 is provided through one side of the rod groove 8. An L-shaped insert rod 10 is movably inserted into the rod groove 8. A tension spring 11 is fixed to the end face of the L-shaped insert rod 10. The other end of the tension spring 11 is fixed to the corresponding side inside the rod groove 8. There are two sets of rod groove 8, adjustment groove 9, L-shaped insert rod 10 and tension spring 11, which are symmetrically arranged at both ends of the positioning strip 7. The slot structure inside the slot 5 is provided with holes and slots that match the specifications and positions of the end face of the L-shaped insert rod 10.

[0019] The above solution involves the precise insertion of the fine mesh shredder 6 into the slot 5 via the positioning strip 7, ensuring accurate installation. The L-shaped insert rod 10, under the action of the tension spring 11, maintains an outward pushing force within the symmetrical rod slots 8 at both ends of the positioning strip 7, ensuring its end is firmly embedded in the holes on both sides of the slot 5. This achieves rapid fixation of the fine mesh shredder 6. The design of the adjustment slot 9 allows operators to easily disassemble the frame by using tools to move the L-shaped insert rod 10, overcoming the spring force. The advantages of this structure are: firstly, convenient installation and disassembly, allowing for quick replacement of different specifications of the fine mesh shredder 6 without complex tools, adapting to the shredding needs of different ingredients; secondly, a secure and reliable fixation, with the tension spring 11 continuously providing pressure to ensure the fine mesh shredder 6 does not loosen or shift during shredding, guaranteeing shredding accuracy. Furthermore, the horizontally positioned fine mesh shredder 6 facilitates efficient direct rinsing to remove residue.

[0020] Reference Figures 2 to 4 The first staggered plate 12 has symmetrically fixed side sliders 14 on both sides, and the side sliders 14 achieve sliding connection with the frame 2 of the equipment. The side sliders 14 have a through-hole 15 for adjusting the distance screw hole 15, and a double screw 16 is screwed through the inside of the adjusting screw hole 15. A holding sleeve 17 is fixedly sleeved on the outer side of the middle section of the double screw 16. The side of the support square rod 3 has a screw insertion hole 18. The double screw 16 is horizontally arranged between two adjacent sets of support square rods 3 through the screw insertion hole 18 structure, and passes through the adjusting screw holes 15 of the two sets of side sliders 14 on the same side. There are two sets of staggered plates 12 and staggered plates 13, and they are all set as plate structures with several sets of hollow strip holes. The four are arranged perpendicular to each other. The hollow strip holes in staggered plates 12 and staggered plates 13 are staggered. The staggered plate 13 also has the same number and specifications of side sliders 14, adjusting screw holes 15, double screws 16 and holding sleeves 17.

[0021] The above scheme is adopted: two sets of staggered rod plates 12 and two sets of staggered rod plates 13 are arranged perpendicularly to each other to form a grid-like adjustable feeding channel. The fasteners at the ends of the side sliders 14 are embedded in the slide rails of the equipment frame 2, providing guidance for the movement of staggered rod plates 12 and 13. The bidirectional screw 16 passes through the adjusting screw hole 15 of the side slider 14. When the holding sleeve 17 is rotated, the bidirectional screw 16 rotates and drives the side sliders 14 on both sides to move inward or outward at the same time, thereby precisely adjusting the spacing between the staggered rod plates. The screw insertion hole 18 is for the bidirectional screw 16. It provides a stable support point. The hollowed-out strips on the two sets of staggered rod plates 12 and 13 are staggered and vertically set in the center to form a rectangular feeding channel without affecting their movement. The advantages of the above structure are: first, high adjustment precision, the spacing between the two sets of staggered rod plates 12 or 13 can be finely adjusted through threaded transmission, which can accurately control the specifications of the feeding channel and adapt to food raw materials of different sizes; second, simple operation, the position of the staggered rod plates on both sides can be adjusted synchronously by simply rotating the handle sleeve 17, which improves the operating efficiency.

[0022] Reference Figure 4 and Figure 6 The moving end of the hydraulic lifting column 19 faces the middle frame 2 of the equipment. The water collection box 20 and the drain box 21 are both coaxially set with the middle frame 2 of the equipment and the hydraulic lifting column 19. A fixed frame 22 is fixedly connected to one side of the middle frame 2. A feeding conveyor belt module 23 is set on the top of the fixed frame 22. The output end of the feeding conveyor belt module 23 is flush with the top surface of the first staggered plate 12 and the second staggered plate 13.

[0023] The above solution is adopted: the moving end of the hydraulic lifting column 19 faces the middle frame 2 of the equipment, and the lifting height can be precisely controlled according to the slicing requirements, providing stable pressure or driving force for the slicing process. The water collection box 20 and the drain box 21 are both coaxially set with the middle frame 2 of the equipment and the hydraulic lifting column 19. This coaxial design can ensure that the cut food and the water generated fall accurately into them. The water collection box 20 can collect the liquid generated during the cutting process, and the drain box 21 can perform preliminary draining of the food to achieve solid-liquid separation. The fixed frame 22 on one side of the middle frame 2 of the equipment provides stable support for the feeding conveyor belt module 23. The output end of the conveyor belt module 23 is flush with the top surfaces of the staggered plate 12 and staggered plate 23, ensuring that the ingredients can be smoothly conveyed into the feeding channel. The advantages of the above structure are that the precise control of the hydraulic lifting column 19 ensures the stability of the shredding pressure and improves the consistency of shredding. At the same time, the coaxial arrangement of the water collection box 20 and the drain box 21 facilitates the collection and separation of ingredients and liquids, keeps the equipment clean, and reduces subsequent processing steps. Secondly, the height matching between the feeding conveyor belt module 23 and the staggered plate realizes automated feeding, reduces the intensity of manual operation, improves production efficiency, and ensures the stability and accuracy of feeding.

[0024] The shredding method of the shredding machine of this invention: The operator, according to the shredding specifications required for the food to be processed, first installs the dense mesh shredding frame 6. The positioning strip 7 on the outer side of the dense mesh shredding frame 6 is aligned with the frame slot 5 on the inner side of the middle section of the equipment frame 2. The dense mesh shredding frame 6 is pushed so that the positioning strip 7 is embedded in the frame slot 5. At this time, the L-shaped inserts 10 at both ends of the positioning strip 7, which pass through the rod slots 8, pop outwards under the elastic force of the tension spring 11. Their ends precisely engage with the matching hole slots on both sides of the frame slot 5, completing the firm fixation of the dense mesh shredding frame 6 and ensuring no displacement during subsequent shredding. Then, the feed channel specifications are adjusted, and the operator rotates the offset plate 12. The holding sleeve 17 corresponding to the staggered rod plate 13 drives the bidirectional screw 16 to rotate in the screw insertion hole 18 of the supporting square rod 3. Since the bidirectional screw 16 is threadedly connected to the adjusting screw hole 15 in the center of the side slider 14, and the side slider 14 is slidably engaged with the middle frame 2 of the equipment, when the bidirectional screw 16 rotates, it will drive the two side sliders 14 to move inward or outward simultaneously, thereby adjusting the distance between the two sets of staggered rod plates 12 and the two sets of staggered rod plates 13. Since the staggered rod plates 12 and 13 are set perpendicular to each other, and the hollow strip holes of the two are staggered, a rectangular feeding channel that is adapted to the specifications of the ingredients is finally formed, laying the foundation for subsequent precise feeding. Next, the automated feeding and shredding process begins. After the equipment is started, the food to be processed is placed on the feeding conveyor belt module 23. The fixed frame 22 on one side of the equipment frame 2 provides stable support for the feeding conveyor belt module 23, ensuring that it does not shake during operation. The feeding conveyor belt module 23 conveys the food to the cutting area. Since its output end is flush with the top surface of the first staggered plate 12 and the second staggered plate 13, the food can slide smoothly into the adjusted rectangular feeding channel, avoiding the food from falling or shifting position due to height difference. Then, the hydraulic lifting column 19 fixed in the center inside the top frame 4 of the equipment is activated. Its moving end descends precisely towards the equipment frame 2, applying stable pressure to the food in the feeding channel and pushing the food downward. Under the pressure, the food contacts the dense mesh shredding frame 6. The mesh structure of the dense mesh shredding frame 6 cuts the food into shreds of the preset specifications, completing the core shredding process. Finally, material collection and solid-liquid separation are performed. After cutting, the shredded ingredients fall downwards under gravity. Since the water collection box 20 and the drain box 21 are coaxially set with the equipment frame 2 and the hydraulic lifting column 19, the shredded ingredients fall precisely into the drain box 21. The juice produced during the cutting process flows through the filter holes of the drain box 21 into the water collection box 20 below, realizing solid-liquid separation of ingredients and juice. After processing, the operator can pull out the water collection box 20 and the drain box 21 connected by the internal slide rail of the equipment base frame 1 to process the collected juice and shredded ingredients respectively. At the same time, if it is necessary to replace the fine mesh shredding frame 6, the L-shaped insert rod 10 can be moved by a tool through the adjustment groove 9 of the positioning strip 7 to compress the tension spring 11 so that the L-shaped insert rod 10 is disengaged from the hole groove of the frame slot 5, and the fine mesh shredding frame 6 can be easily taken out for replacement or cleaning.

[0025] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
