Description

Technical Field

[0001] This utility model relates to the technical field of centrifugal dehydration devices, and in particular to a centrifugal dehydration device for food research. Background Technology

[0002] To ensure the safety of meat products, special studies on microbial residues and component stability are required for dehydrated meat. Therefore, centrifugal dehydration is necessary before conducting meat food safety research.

[0003] Existing food-grade centrifugal dehydration equipment has an outer cylinder fixedly connected to the base. During the dehydration process, the juices from meat products will be splashed onto the inner wall of the outer cylinder. If it is not maintained and cleaned in time after dehydration, bacteria can easily grow, which can lead to secondary contamination of the meat and affect the accuracy of subsequent safety studies. In addition, because the outer cylinder is fixedly connected to the base, there are dead corners during cleaning, making it difficult to clean thoroughly.

[0004] In summary, we propose a centrifugal dehydration device for food research, aiming to solve the aforementioned problems. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0020] like Figures 1-7As shown, a centrifugal dehydration device for food research includes a base 1. A control plate is provided on the side wall of the base 1, and the control plate is electrically connected to the electrical control components of the device. Support legs are installed at the bottom of the base 1. An outer cylinder 2 is snap-fitted to the top of the base 1, which allows for quick assembly and disassembly of the outer cylinder 2. A rotating rod 3 is rotatably connected to the center of the bottom wall of the outer cylinder 2. A drive assembly 4 for rotating the rotating rod 3 is provided between the base 1 and the rotating rod 3. A sieve cylinder 5 is sleeved in the center of the inner part of the outer cylinder 2. A transmission assembly 6 for rotating the sieve cylinder 5 is provided between the sieve cylinder 5 and the rotating rod 3. A mesh bag 7 is sleeved inside the sieve cylinder 5. The mesh bag 7 directly holds the meat to be dehydrated, avoiding direct contact between the meat and the sieve cylinder 5, which would cause juice residue to stick together. A fixing assembly 8 is provided between the mesh bag 7 and the sieve cylinder 5 to align the walls of the two and prevent relative displacement, thus preventing uneven dehydration of the meat due to shaking and squeezing of the mesh bag 7.

[0021] Furthermore, the outer cylinder 2 includes a lower cylinder 21, with an upper cylinder 22 coaxially nested at the top of the lower cylinder 21. This nesting structure facilitates the separation of the upper cylinder 22 and the lower cylinder 21, making it convenient to clean the inner walls separately. A sealing ring is provided at the nesting point of the lower cylinder 21 and the upper cylinder 22, which can fill the gap between the two to prevent juice from leaking from the nesting point during centrifugation. A drain pipe is welded to the outer surface of the lower cylinder 21, which is connected to the interior of the lower cylinder 21, allowing the juice collected at the bottom of the lower cylinder 21 to be discharged quickly, preventing juice from remaining inside the cylinder. Two symmetrical handles are welded to the outer surface of the lower cylinder 21, and two symmetrical handles are welded to the outer surface of the upper cylinder 22.

[0022] Furthermore, a cover 9 is coaxially nested at the top of the upper cylinder 22, and the cover 9 completely covers the opening of the upper cylinder 22 to prevent the centrifugal force generated by high-speed rotation from throwing the meat or juices out of the cylinder.

[0023] Furthermore, a positioning ring 10 is fixedly connected to the top of the base 1. The positioning ring 10 can initially position the installation position of the lower cylinder 21 and limit the radial displacement of the lower cylinder 21. Multiple positioning blocks 11 are circumferentially distributed inside the positioning ring 10 with its center as the axis. The lower cylinder 21 is fitted into the inside of the positioning ring 10. Multiple positioning grooves 12 corresponding to the positioning blocks 11 are opened at the bottom of the lower cylinder 21. Each positioning groove 12 is fitted into the corresponding positioning block 11. The cooperation structure between the positioning block 11 and the positioning groove 12 can further limit the circumferential rotation of the lower cylinder 21, making the installation of the outer cylinder 2 on the base 1 more secure.

[0024] Furthermore, the rotary drive assembly 4 includes a second rotary rod 41, which is rotatably connected to the center of the positioning ring 10 at the top of the base 1. A motor 42 is installed on one side of the positioning ring 10. The output shaft of the motor 42 and the second rotary rod 41 are connected inside the base 1 via a synchronous pulley and a synchronous belt. A receiving groove 43 is provided at the center of the bottom of the lower cylinder 21. A first ring block 44 is fixedly connected to the top of the second rotary rod 41, and a second ring block 45 is fixedly connected to the bottom of the first rotary rod 41. Both the first ring block 44 and the second ring block 45 are fitted inside the receiving groove 43. On the side of ring 44 and ring 2 45 that are close to each other, there are multiple helical teeth 46 arranged in a circular pattern and meshing with each other. When the outer cylinder 2 is fitted with the base 1, the helical teeth 46 of ring 1 44 and ring 2 45 can automatically mesh to quickly establish a power transmission link. When the outer cylinder 2 is disassembled, the two can be easily separated without affecting the cleaning operation of the outer cylinder 2. When the motor 42 is started, the motor output shaft drives the rotating rod 2 41 to rotate through the synchronous pulley and synchronous belt. Ring 1 44 and ring 2 45 transmit power through the meshing helical teeth 46, so that the rotating rod 3 rotates synchronously.

[0025] Furthermore, the transmission assembly 6 includes a turntable 61, which is fitted into the center of the lower cylinder 21. The bottom of the screen cylinder 5 abuts against the top of the turntable 61. A splined shaft 62 is fixedly connected to the top of the rotating rod 3 inside the lower cylinder 21. A splined cylinder 63, adapted to the splined shaft 62, is fixedly connected to the center of the bottom of the turntable 61. The splined shaft 62 and the splined cylinder 63 are keyed together. This splined connection enables the rotating rod 3 and the turntable 61 to rotate synchronously, and allows for easy disassembly. For convenience and ease of subsequent cleaning, the bottom wall of the sieve cylinder 5 has multiple circumferentially distributed positioning holes 64, and a positioning post 65 is fitted into each positioning hole 64. The multiple positioning posts 65 are fixedly connected to the top of the turntable 61. The spline shaft 62 at the top of the rotating rod 3 is keyed to the spline cylinder 63 at the bottom of the turntable 61, driving the turntable 61 to rotate. The positioning post 65 at the top of the turntable 61 is inserted into the positioning hole 64 on the bottom wall of the sieve cylinder 5, thereby driving the sieve cylinder 5 and the mesh bag 7 to rotate at high speed synchronously.

[0026] Furthermore, the body of the mesh bag 7 is fitted inside the screen cylinder 5, and the opening of the mesh bag 7 is turned outward and covers the edge of the opening of the screen cylinder 5, so that the mesh bag 7 can be fixed by the fixing component 8 later, and it is also convenient for the operator to grab the opening and take out the mesh bag 7 after dehydration.

[0027] Furthermore, the fixing component 8 includes a convex ring 81, which is welded to the edge of the opening of the screen cylinder 5. The convex ring 81 can support the outward opening of the mesh bag 7. An elastic pressure ring 82 is provided on the outer side of the convex ring 81 to clamp the outward opening of the mesh bag 7. The elastic pressure ring 82 uses its own elasticity to tightly clamp the outward opening of the mesh bag 7 onto the convex ring 81, thereby fixing the top of the mesh bag 7. Multiple female buckles 83 are distributed circumferentially at the bottom of the mesh bag 7. The fastening structure of the female buckles 83 and male buckles 84 can fix the bottom of the mesh bag 7. Multiple male buckles 84 that are compatible with the female buckles 83 are distributed circumferentially on the inner wall of the bottom wall of the screen cylinder 5. The number of male buckles 84 is greater than the number of female buckles 83, which facilitates flexible adjustment of the fastening position of the female buckles 83 and male buckles 84. In other embodiments, multiple circumferentially distributed hanging rings and multiple circumferentially distributed hooks can be installed at the bottom of the mesh bag 7. The multiple hooks and multiple hanging rings can be used to fix the bottom of the mesh bag 7.

[0028] Working principle: First, the bottom positioning groove 12 of the lower cylinder 21 of the outer cylinder 2 is aligned and fitted with the positioning block 11 in the positioning ring 10 on the base 1. The outer cylinder 2 and the base 1 are fixed by the snap-fit ​​structure to prevent displacement during operation. During this process, the ring block 44 at the top of the rotating rod 2 41 and the ring block 45 at the bottom of the rotating rod 3 automatically mesh with the helical teeth 46 on their surfaces to complete the connection of the power transmission link. Then, the upper cylinder 22 is coaxially nested on the top of the lower cylinder 21, and the sealing ring between the two is used to ensure the sealing of the device.

[0029] Insert the mesh bag 7 into the inside of the sieve cylinder 5, turn the bag opening outwards and cover the edge of the sieve cylinder 5 opening. The convex ring 81 at the opening of the sieve cylinder 5 and the elastic pressure ring 82 cooperate to clamp the outwardly turned part of the mesh bag 7. At the same time, fasten the female buckle 83 at the bottom of the mesh bag 7 with the male buckle 84 on the inner wall of the bottom of the sieve cylinder 5 to prevent the mesh bag 7 from shifting relative to the sieve cylinder 5 during centrifugation. Finally, put the meat to be dehydrated into the fixed mesh bag 7.

[0030] The motor 42 is started, and the output shaft of the motor drives the rotating rod 41 to rotate through the synchronous pulley and synchronous belt. The ring block 44 and the ring block 45 transmit power through the meshing helical teeth 46, so that the rotating rod 3 rotates synchronously. The spline shaft 62 at the top of the rotating rod 3 is keyed to the spline cylinder 63 at the bottom of the turntable 61, which drives the turntable 61 to rotate. The positioning pin 65 at the top of the turntable 61 is inserted into the positioning hole 64 on the bottom wall of the screen cylinder 5, thereby driving the screen cylinder 5 and the mesh bag 7 to rotate synchronously at high speed. Under the action of centrifugal force, the juice in the meat penetrates the gap between the mesh bag 7 and the screen cylinder 5, is thrown to the inner wall of the outer cylinder 2, and finally collects along the inner wall to the bottom of the lower cylinder 21, and is discharged through the drain pipe on the outer surface of the lower cylinder 21, thus completing the dehydration.

[0031] After dehydration, open the cover 9, remove the elastic pressure ring 82, unconnect the female buckle 83 and male buckle 84, take out the mesh bag 7 and the dehydrated meat, then pull it upwards using the handle 2 of the upper cylinder 22, and then grasp the handle 1 of the lower cylinder 21 to remove the outer cylinder 2 from the positioning ring 10 of the base 1. Next, take out the turntable 61 and thoroughly clean the mesh bag 7, sieve cylinder 5, upper cylinder 22, lower cylinder 21 and turntable 61 to prevent bacterial growth.
