[0001] The present application relates to the technical field of food inspection, and in particular to a multi-channel filtering device for food inspection pretreatment. Background Art

[0002] Food inspection generally refers to a process of studying and evaluating food quality and its changes. It is based on some basic theories and various technologies of physics, chemistry and biochemistry, and in accordance with established technical standards, such as international and national food hygiene / safety standards, to inspect the quality of food raw materials, auxiliary materials, semi-finished products, finished products and by-products to ensure that the product quality is qualified.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-4 This application is described in further detail.

[0030] The present application discloses a multi-channel filtration device for food inspection pretreatment. Figure 1-4 A multi-channel filtering device for food inspection and pretreatment comprises a bottom plate 1, a filtering mechanism 2 is fixedly connected to the top of the bottom plate 1, the filtering mechanism 2 comprises a filter cartridge 21, the filter cartridge 21 is arranged on the top of the bottom plate 1, a feed cavity 22 is provided on the filter cartridge 21, the feed cavity 22 is uniformly spaced and surrounded on the filter cartridge 21, a filter plate 23 is fixedly connected inside the feed cavity 22, an annular plate 24 is arranged outside the filter cartridge 21, the filter cartridge 21 penetrates the annular plate 24 and is slidably connected to the annular plate 24, a limiting groove 25 is provided on the filter cartridge 21, a limiting plate 26 is fixedly connected to the outside of the filter cartridge 21, the limiting plate 26 penetrates the limiting groove 25 and matches the limiting groove 25, a square plate 27 is provided on the top and bottom of the limiting groove 25, and the square plate 27 is fixedly connected to the annular plate 24;

[0031] A support rod 28 is fixedly connected to the top of the bottom plate 1, and the support rod 28 is fixedly connected to the outer side of the annular plate 24. A round rod 29 is fixedly connected between the upper and lower adjacent square plates 27, and the round rod 29 penetrates the limit plate 26. The top and bottom of the limit plate 26 are fixedly connected with springs 291, and the spring 291 is fixedly connected to the square plate 27. The round rod 29 penetrates the spring 291. An oscillation motor 292 is fixedly connected to the bottom of the filter cartridge 21, and the crushed food sample particles are put into the feed cavity 22 on the filter cartridge 21. During filtering, the oscillation motor 292 works in coordination with the elastic force of the spring 291, which can effectively realize the rapid shaking of the filter cartridge 21, thereby prompting the sample particles that meet the standards to quickly pass through the filter plate 23 and fall, so as to achieve the filtering purpose. During the filtering process, different food sample particles can be respectively put into different feed cavities 22 for synchronous filtering, so as to avoid the situation in which different food samples need to be filtered in sections in a single-channel filtering device, which is more time-consuming.

[0032] A feed hopper 293 is provided at the top of the feed chamber 22, and a discharge hopper 294 is provided at the bottom of the feed chamber 22. The feed hopper 293 and the discharge hopper 294 are respectively fixedly connected to the top and bottom of the filter cartridge 21. The feed hopper 293 increases the feed opening to prevent the material from spilling to the outside during the feeding process. A discharge port 295 is provided on the outside of the filter cartridge 21, and the discharge port 295 is communicated with the feed chamber 22. A baffle 296 is provided on the outside of the filter cartridge 21, and the baffle 296 is connected to the filter cartridge 21 by threads. The filtered residue is discharged through the discharge port 295.

[0033] The filtering mechanism 2 includes a material receiving assembly, which includes a placing plate 297, the placing plate 297 is fixedly connected to the top of the bottom plate 1, a placing opening is opened on the placing plate 297, a material storage cup 298 is arranged on the top of the placing plate 297, the material storage cup 298 is placed inside the placing opening and matches the placing opening, the material storage cup 298 is arranged at the bottom of the discharge hopper 294, and the filtered particles enter the discharge cup for storage, a circular plate 299 is arranged on the top of the bottom plate 1, and a plug plate 281 is slidably connected to the top of the bottom plate 1, the plug plate 281 extends into the inside of the placing opening, and the plug plate 281 is connected to the outside of the storage cup 298. The outer side of the circular plate 299 is movably connected to a push-pull plate 282 through a movable hinge seat, and one end of the push-pull plate 282 is movably connected to the top of the plug plate 281 through a movable hinge seat. The circular plate 299 can drive the push-pull plate 282 to flip during its up and down movement. A cylinder 283 is fixedly connected to the bottom of the circular plate 299, and the bottom of the cylinder 283 is fixedly connected to the top of the base plate 1. After the cylinder 283 works, the circular plate 299 can be pushed and pulled up and down. Two limit rods 284 are fixedly connected to the top of the base plate 1, and the two limit rods 284 both penetrate the circular plate 299, and the limit rods 284 can provide a limit for the circular plate 299.

[0034] In the actual operation process, the crushed food sample particles are put into the feeding cavity 22 on the filter cartridge 21, and the oscillation motor 292 works to make the filter cartridge 21 vibrate. At this time, the filter cartridge 21 drives the limit plate 26 to vibrate. Since the spring 291 exerts an elastic force on the limit plate 26, the filter cartridge 21 can be effectively shaken quickly. During the shaking process, the sample particles that meet the standards can pass through the filter plate 23 and fall into the discharge hopper 294, and finally fall into the storage cup 298 for storage. The setting of 94 can reduce the scattering range of the material falling, so that the material can fully fall into the storage cup 298. When the filtered residue needs to be discharged, the baffle 296 is directly rotated to control the baffle 296 to move to the top of the discharge port 295, and the residue can slide out through the discharge port 295. In this process, different food sample particles can be respectively put into different feed chambers 22 for synchronous filtration, thereby avoiding the situation in which different food samples need to be filtered in sections in a single-channel filtering device, which is more time-consuming.

[0035] When the insert plate 281 is close to the storage cup 298, it can provide a limit for the storage cup 298 to ensure the stability of the storage cup 298 when it is placed. When the storage cup 298 needs to be removed, the cylinder 283 pushes the circular plate 299 after working, and the circular plate 299 moves upward. The circular plate 299 drives the push-pull plate 282 to flip over. After the push-pull plate 282 flips over, the insert plate 281 is pulled until it is no longer in contact with the storage cup 298. At this time, the storage cup 298 can be removed. Similarly, when the circular plate 299 moves downward, the insert plate 281 can re-squeeze and limit the placed storage cup 298, effectively ensuring the stability of the material receiving process.

[0036] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
