Description

Technical Field

[0001] This utility model belongs to the field of food processing equipment, and in particular relates to a chicken strip shredding device. Background Technology

[0002] Chicken strips are a classic snack made primarily from chicken breast. Through slicing, marinating, coating in batter, and deep-frying, they achieve a crispy exterior and tender, juicy interior. Currently, food factories primarily process chicken strips using automated machinery.

[0003] Cleaned chicken breasts are processed manually or automatically to remove tendons, fat, and connective tissue from their surface, ensuring the purity of the raw materials. Then, they are conveyed to an automatic shredder via a conveyor belt to be shredded. After shredding, the chicken is marinated, coated with batter, deep-fried to set its shape, and then cooled and frozen to obtain the finished chicken strips.

[0004] The automatic shredders used are generally rotary shredders, which cut chicken breast by having two bladed rotary blades rotate inward simultaneously. However, due to the uneven thickness of the chicken breast and the design of the rotary blades, the chicken breast cannot expand, resulting in inconsistent thickness of the final cut chicken strips. Therefore, how to make the thickness of the chicken strips as consistent as possible is an area that needs improvement. Utility Model Content

[0005] This invention addresses the technical problems existing in the cutting of chicken breast by proposing a chicken strip shredding device that is reasonably designed, simple in structure, easy to process, and can keep the thickness of chicken strips roughly uniform.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a chicken strip shredding device, including a lifting conveyor belt and a rotary shredder disposed below the lifting conveyor belt. The rotary shredder includes a frame and a shredding drum disposed on the frame. A first shredding rotary cutter and a second shredding rotary cutter are disposed inside the shredding drum, with the first and second shredding rotary cutters arranged opposite to each other inside the shredding drum. A drive motor for driving the first shredding rotary cutter to rotate is also disposed on the frame. A discharge port is disposed at the bottom of the shredding drum. A first shredding rotary cutter is also disposed inside the shredding drum. The first and second extrusion rollers are arranged opposite each other and are positioned above the first and second shredding rollers. The first and second extrusion rollers are rotatably disposed inside the shredding drum. The first shredding roller is connected to the drive motor by a belt. A drive gear is fitted on the end of the first shredding roller away from the belt. A driven gear that meshes with the first shredding roller is provided on the second shredding roller. The first shredding roller is connected to the first extrusion roller by a belt, and the second shredding roller is connected to the second extrusion roller by a belt.

[0007] Preferably, the shredding drum is further provided with a pressing roller spacing adjustment mechanism. The pressing roller spacing adjustment mechanism includes an adjustment frame disposed on the shredding drum. The adjustment frame is disposed at both ends of the first pressing roller and the second pressing roller. The adjustment frame is provided with two spaced-apart adjustment blocks. The adjustment blocks are provided with bearings. The rotating shaft of the first pressing roller or the second pressing roller is fitted into the bearings. The adjustment blocks are slidably disposed on the adjustment frame.

[0008] Preferably, an adjusting screw is provided on the side of the adjusting block away from the other adjusting block. The adjusting screw is rotatably mounted on the adjusting block, and the end of the adjusting screw away from the adjusting block passes through the adjusting frame and is threadedly connected to the adjusting frame.

[0009] Preferably, the outlet end of the lifting conveyor belt is also provided with a guide plate, which extends between the first extrusion roller and the second extrusion roller.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This utility model provides a chicken strip shredding device. By improving the existing structure, the first and second extrusion rollers are used to extrude the chicken breast meat, so that the overall thickness is consistent when it enters the shredding roller position. This makes the thickness of the cut chicken strips consistent, thereby making the finished chicken strips have consistent specifications and improving the competitiveness of the product.

[0013] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0014] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0015] Example 1, such as Figures 1-4 As shown, this embodiment aims to ensure that the thickness of each cut chicken strip is as uniform as possible. To achieve this, the chicken strip shredding device provided in this embodiment includes a lifting conveyor belt 1 and a rotary shredder set below the lifting conveyor belt 1. The main purpose of the lifting conveyor belt 1 is to raise the height of the chicken breast so that it falls freely into the rotary shredder.

[0016] The rotary shredder includes a frame 21 and a shredding drum 2 mounted on the frame 21. A first shredding rotary cutter 3 and a second shredding rotary cutter 4 are installed inside the shredding drum 2, positioned opposite each other. Both cutters rotatably within the drum 2. The shafts of the first and second cutters are centrally symmetrical, but their rollers have staggered annular blades. A drive motor 5 for rotating the first cutter 3 is also mounted on the frame 21. In this embodiment, the power end of the drive motor 5 is connected to a pulley 6, and a pulley 6 is also mounted on the shaft of the first cutter 3. The two pulleys 6 are connected by a belt. A discharge port 22 is located at the bottom of the shredding drum 2. The frame 21 is primarily designed to raise the height of the shredding drum 2, allowing for the placement of a collection basin below it. If vacuum tumbling and marinating is used, a conveyor belt can be installed on the frame 21.

[0017] The above structure is a common structure in existing industrial processing, therefore, it will not be described in detail in this embodiment.

[0018] Considering that chicken breast meat falls onto the slicing roller, and the circular blade of the slicing roller directly cuts the chicken breast instead of squeezing it, and given that chicken breast meat varies in thickness, the resulting chicken strips will have varying thicknesses. For example, in thicker areas of chicken breast, the strips will be fuller, while in thinner areas, they will be less thick. Therefore, to improve the uniformity of thickness, the chicken breast meat should be as flat as possible. To achieve this, the slicing barrel 2 provided in this embodiment is further equipped with a first compression roller 7 and a second compression roller 8. The first compression roller 7 and the second compression roller 8 are arranged opposite each other and above the first slicing roller 3 and the second slicing roller 4. More specifically, the first compression roller 7 is positioned above the first slicing roller 3, and the second compression roller 8 is positioned above the second slicing roller 4. The first compression roller 7 and the second compression roller 8 are also symmetrically arranged about the center line of the slicing barrel 2.

[0019] Meanwhile, the first extrusion roller 7 and the second extrusion roller 8 are rotatably set inside the shredding barrel 2. In this way, when the chicken breast falls into the shredding barrel 2, it is first squeezed and flattened by the first extrusion roller 7 and the second extrusion roller 8, and then enters between the first shredding roller 3 and the second shredding roller 4 for shredding. In this way, it can be ensured that the thickness of the shredded meat is basically consistent (of course, the length cannot be guaranteed to be consistent).

[0020] To save energy, in this embodiment, a drive gear is mounted on the shaft at the end of the first shredding cutter 3 furthest from the pulley 6, and a driven gear meshing with the first shredding cutter 3 is mounted on the shaft at the same end of the second shredding cutter 4. This ensures that the first shredding cutter 3 and the second shredding cutter 4 rotate in opposite directions, thus ensuring that they both rotate inward. Simultaneously, pulleys 6 are also mounted on the shafts of the first extrusion roller 7, the second extrusion roller 8, and the second shredding cutter 4. Of course, the pulley on the first shredding cutter 3 is a double-groove pulley. The first extrusion roller 7 and the first shredding cutter 3 are connected by a belt, and the second shredding cutter 4 is connected by a belt to the second extrusion roller 8. This also ensures that the first extrusion roller 7 and the second extrusion roller 8 rotate in opposite directions, and both rotate inward.

[0021] Considering that the first slicing roller 3 and the second slicing roller 4 cut in an alternating manner, chicken breast meat within a certain thickness range can be cut. Since the first extrusion roller 7 and the second extrusion roller 8 only need to adjust their spacing, different thicknesses of chicken breast meat can be extruded, eliminating the need to replace the slicing rollers. Therefore, in this embodiment, an extrusion roller spacing adjustment mechanism 9 is also provided on the slicing drum 2. Specifically, the extrusion roller spacing adjustment mechanism 9 includes an adjustment frame 91 disposed on the slicing drum 2, located at both ends of the first extrusion roller 7 and the second extrusion roller 8. The adjustment frame 91 is generally rectangular. The frame is designed in the form of a frame. Notches are cut into the side plates of the shredding drum 2. The top and bottom bars of the adjusting frame 91 are fixed to the side plates of the shredding drum 2 by welding. The middle of the top and bottom bars of the adjusting frame 91 is provided with sliding grooves. Two adjusting blocks 92 are set on the adjusting frame 91 at intervals. The adjusting blocks 92 are generally rectangular blocks with sliding protrusions at the top and bottom ends that cooperate with the sliding grooves. Then, the two adjusting blocks 92 are inserted between the top and bottom bars. Of course, since the adjusting blocks 92 are provided with bearings 93, the adjusting blocks 92 are first installed at both ends of the extrusion roller before being inserted.

[0022] Meanwhile, an adjusting screw 94 is provided on the side of the adjusting block 92 away from the other adjusting block 92. The adjusting screw 94 is rotatably mounted on the adjusting block 92. Specifically, the adjusting block 92 has a mounting hole 921, which is located on one side of the bearing 93. The adjusting screw 94 extends through the side wall of the adjusting block 92 into the mounting hole 921. An adjusting nut 95, which mates with the adjusting screw 94, is provided in the mounting hole 921. The diameter of the adjusting nut 95 is larger than the diameter of the through hole on the adjusting block 92, while the diameter of the through hole is slightly larger than the diameter of the adjusting screw 94. This ensures that the adjusting screw 94 can rotate relative to the adjusting block 92 and can also push and pull the adjusting block 92. The end of the adjusting screw 94 away from the adjusting block 92 passes through the adjusting frame 91 and is threadedly connected to the adjusting frame 91. This achieves both fixing and sliding of the adjusting block 92.

[0023] By rotating the adjusting screw 94, the distance between the first extrusion roller 7 and the second extrusion roller 8 can be adjusted to meet the extrusion requirements of chicken breast of different thicknesses. This allows for the replacement of the slicing roller, providing another way to adjust the size of the chicken strips. The belt drive connection is sufficient for the limited range of motion, eliminating the need to change the drive connection method.

[0024] To ensure that the chicken breast meat accurately enters between the first extrusion roller 7 and the second extrusion roller 8, a guide plate 11 is also provided at the exit end of the lifting conveyor belt 1, extending between the first extrusion roller 7 and the second extrusion roller 8. In this embodiment, side plates are installed on both sides of the guide plate 11, and holes are provided on the side plates so that the guide plate 11 can be installed on the profile frame of the lifting conveyor belt 1. The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
