Technical Field

[0001] The present invention relates to the technical field of food detection, and more specifically to a food moisture content detection device and a detection method, and their application in food production. Background Art

[0002] The food moisture content detection device is a device used to measure the moisture content in food. It is widely used in many fields such as food processing, agricultural product processing, and grain storage. By accurately measuring the moisture content in food, the quality and safety of the product can be ensured, and it also helps to optimize the production process and reduce energy consumption and costs. The moisture content of the final product is also one of the important indicators of quality inspection. By regularly sampling the finished products, it can be ensured that each batch of products meets the prescribed moisture content standards, meets food safety requirements, and helps to improve the uniformity of the product.

[0003] As a processed meat product, the moisture content of sausage is one of the important factors affecting product quality, taste and shelf life. Accurately measuring the moisture content in sausage is crucial to ensuring product quality. For example, the Chinese patent with application number 202311211633.2 discloses a processing device for detecting the moisture content of meat filling, the structure of which includes a processing box, an air pressure control device, a heating device and a collecting device. The processing box is cylindrical and is provided with a cover body; the air pressure control device includes a piston plate and a linear drive assembly; the piston plate is slidably installed in the processing box, and the piston plate divides the inner cavity of the processing box into an upper cavity and a lower cavity. When the cover body is tightly matched with the processing box, the upper cavity and the lower cavity are both in a closed state; the linear drive assembly is arranged on the processing box and is used to drive the piston plate to move; the heating device includes a mounting frame, which is installed on the processing box; a processing box is installed on the mounting frame, and a heating net is provided on the processing box; the collecting device is arranged in the upper cavity and is used to collect water vapor evaporated from the meat filling. The processing device for detecting the moisture content of meat fillings can detect the moisture content of meat fillings during production, thereby improving the accurate collection of the moisture content of meat fillings.

[0004] The Chinese patent with application number 201711251834.X discloses a food inspection meat moisture content detection device, which has a structure that a box cover is placed on the box opening of the main box, two sealing sleeves are placed on the box cover respectively, two exhaust channels are placed on the inner wall of the main box, a support plate is placed in the main box, the outer edge of the support plate is connected to the inner wall of the main box, an arc-shaped protrusion is placed in the middle of the support plate, a water storage cavity is placed between one side of the support plate and the bottom of the main box, and the water storage cavity is connected to the two exhaust channels respectively, a plurality of strip grooves are opened on the support plate, a protective pad is placed on one side of the support plate, and a plurality of puncture needles are placed on the protective pad respectively, two drainage plates are placed on one side of the support plate respectively, and correspond to one end of the two exhaust channels respectively, and the drainage plate is an arc-shaped plate structure. This food inspection meat moisture content detection device can squeeze the meat to squeeze out the water inside it, so as to observe and detect the moisture content.

[0005] The current devices for detecting the moisture content of food still have the following problems: When testing, it is necessary to manually collect samples of the product and then send them to the equipment for testing, which not only wastes manpower but also has low testing efficiency.

[0006] Current moisture content testing equipment can only test products before packaging. When it is necessary to test the packaged products, the packages need to be opened manually and then sent to the testing equipment for testing. There is a lack of equipment that can test the final product.

[0007] After the test, the sampling tools need to be cleaned manually to avoid residual samples. At the same time, they need to be dried after cleaning to prevent residual liquid from affecting subsequent tests. Cleaning the tools will increase the labor intensity of the workers and reduce the efficiency of the test.

[0008] When current detection devices clamp products, they can only clamp products of the same size. When changing products of different sizes, the clamping device needs to be adjusted, resulting in the detection device being unable to adapt to products of different sizes.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical scheme and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention, that is, the embodiments described are only part of the embodiments of the present invention, rather than all of the embodiments. The components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0028] Depend on Figures 1 to 14 Given, including: A workbench 101, wherein a protective cover 102 is connected to the top of the workbench 101, and the protective cover 102 protects the internal equipment and reduces the entry of outside air into the detection area. A door is provided on the protective cover 102; A rotating assembly, which is used to drive the clamping assembly to rotate so that the clamping assembly can drive the product to move to the next process. The rotating assembly drives the product to move to the next step. The rotating assembly includes a rotating support table 201 fixed on the workbench 101, and a rotating rod 202 rotatably connected to the inside of the rotating support table 201. The rotating rod 202 rotates inside the rotating support table 201. The rotating rod 202 is transmission-connected to a driving device in the workbench 101. The rotating rod 202 and the workbench 101 are preferably a disc assembly line. A turntable 203 is connected to the top of the rotating rod 202. The bottom of the turntable 203 has a clamping assembly in an evenly spaced circular array. The clamping assembly is fixed on the turntable 203 and moves with the rotation of the turntable 203. The number of clamping assemblies is preferably eight. The rotation angle of a single turntable 203 is 45 degrees. The clamping assembly includes a receiving plate 204 for carrying food. The top of the receiving plate 204 is recessed inward so that the product can be centered. The feeding assembly is used to convey the external product to the designated position, so as to facilitate the clamping assembly to take it away. The feeding assembly includes a feeding conveyor belt 301 fixed on the workbench 101 and a feeding plate 302 connected to one end of the feeding conveyor belt 301. The feeding plate 302 is located on the top of the receiving plate 204. The height of the feeding plate 302 is higher than the receiving plate 204 and the rack baffle 709 at one end of the receiving plate 204. The feeding plate 302 is provided with a groove for positioning the food, so that the product can reach the designated position; The incision assembly is used to open a sampling port on the product to facilitate sampling and testing of internal samples. The incision assembly includes an incision support frame 401 fixed to the top of the workbench 101, a third hydraulic cylinder 402 located on the top of the incision support frame 401, and a telescopic cutter assembly 403. The telescopic cutter assembly 403 includes an internal cutting knife 409. The receiving plate 204 is provided with an incision groove 216 that cooperates with the telescopic knife assembly. The cutting knife 409 can enter the incision groove 216. When the clamping assembly moves, a sampling port is cut out at the bottom of the product. A sampling assembly is used to sample the internal sample of the product for testing. The sampling assembly includes a sampling support frame 501 fixed on the top of the workbench 101, a fixed disk 502 connected to the sampling support frame 501, a rotating disk 503 and a pushing assembly 504 located on the fixed disk 502, and a collecting assembly uniformly distributed on the rotating disk 503. The rotating disk 503 drives the collecting assembly to rotate, so as to perform sampling, pushing out testing, cleaning and drying steps. The collecting assembly includes a collecting tube 506 and a scraper 507 located on the inner wall of one end of the collecting tube 506. The collecting tube 506 is hollow and the scraper 507 is located on one side. When the collecting tube 506 rotates, the scraper 507 will scrape the product sample off. The detection component detects the sample through infrared detection technology, which has the function of non-contact detection, and is fast and efficient. The detection component includes symmetrically arranged detection conveyor belts 601, a transfer platform 602 located between the symmetrical detection conveyor belts 601, and a detection device 603 connected to the detection conveyor belts 601. The detection device 603 is preferably an infrared moisture detector, which detects the moisture content in the sample through infrared rays. The device is a mature device and will not be described in detail here. The transfer platform 602 is located on the rotating disk 5 03, a square groove 604 matching with the collection tube 506 is provided on the transfer platform 602. Specifically, when the collection tube 506 rotates to the top of the square groove 604 inside the transfer platform 602, the detection conveyor belt 601 will convey the detection vessel to the bottom of the collection tube 506, and the discharge push rod 522 will push the material blocking cover 513 to push the sample out of the collection tube 506. After the sample falls on the detection vessel, the detection conveyor belt 601 drives it to move to the bottom of the detection device 603 to detect the water content of the sample; The unloading component is used to transport the sampled products. The unloading component includes a recovery box 701 connected to the top of the workbench 101 and a recovery hopper 702 connected to the top of the recovery box 701 to collect the tested products in a unified manner.

[0029] Since the products to be inspected vary in size and shape, the clamping assembly may not be able to clamp different types of products. The following provides a structure that can clamp products of different sizes: Figure 3 and Figure 4Specifically, the clamping assembly also includes a guide frame 205 connected to the top of the receiving plate 204, a moving plate 206 connected to the guide frame 205, and a symmetrical clamping plate 207 located at the bottom of the moving plate 206. The clamping plate 207 is in an arc shape. The guide frame 205 is internally connected with a second hydraulic cylinder 208 and symmetrically distributed guide rods 410. The output end of the second hydraulic cylinder 208 pushes the moving plate 206 to move up and down along the guide rod 410. The moving plate 206 is slidably connected to the guide rod 410. The bottom of the moving plate 206 is connected with a symmetrical arc-shaped support plate 210, and the opposite ends of the symmetrical clamping plates 207 are both rotatably connected to the arc-shaped support plate 210. One end of the clamping plate 207 is rotatably connected to the arc-shaped support plate 210, and the clamping plate 207 and the movable plate 206 are connected by a spring. The spring pushes the symmetrical clamping plate 207 to move to the middle position, so that it has the function of clamping toward the middle. The arc-shaped support plate 210 is provided with symmetrically arranged arc grooves 211, and the two sides of the clamping plate 207 are connected with protrusions located in the arc grooves 211. The arc grooves 211 play a role of limiting, preventing the two clamping plates 207 from being too close to each other and affecting the clamping of the product. One side of the guide frame 205 is connected with a material receiving baffle 212. Specifically, when the clamping assembly rotates, one end of the product will contact the material receiving baffle 212, so that it moves with the clamping assembly. When the rotation exceeds the feed plate 302, the product will fall on the receiving plate 204 at the bottom. When the clamping assembly moves to the top of the feed plate 302, the moving plate 206 needs to be located at the top to prevent the clamping plate 207 at the bottom from affecting the movement of the product. The following provides a structure for automatically rising when the clamping assembly moves to the feed plate 302: Figure 3 and Figure 4 The output end of the second hydraulic cylinder 208 is connected to the top of the moving plate 206. A spring is connected between the bottom of the moving plate 206 and the receiving plate 204. The spring pushes the symmetrical clamping plates 207 to clamp toward the center position. The bottom of the receiving plate 204 close to the turntable 203 is connected to the first hydraulic cylinder 213. The top of the rotating support platform 201 is connected to the cam plate 214. Figure 4The diameter of the cam disc 214 between the feeding plate 302 and the recovery hopper 702 is smaller than that of other parts. When the output end of the first hydraulic cylinder 213 on one side of the clamping assembly moves to this point, the output end of the first hydraulic cylinder 213 will extend outward, so that the hydraulic oil in the second hydraulic cylinder 208 moves toward the first hydraulic cylinder 213, and the output end of the second hydraulic cylinder 208 drives the movable plate 206 to move upward, thereby reducing the impact of the clamping plate 207 on the product. The output end of the first hydraulic cylinder 213 is slidably connected to the outer annular surface of the cam disc 214. Specifically, the output end of the first hydraulic cylinder 213 is connected to a rolling wheel in contact with the outer wall of the cam disc 214. The first hydraulic cylinder 213 and the second hydraulic cylinder 208 are connected by an oil pipe 215. When the first hydraulic cylinder 213 passes through the feeding plate 302, due to the increase in the diameter of the cam disc 214, the hydraulic oil in the first hydraulic cylinder 213 will be pressed into the second hydraulic cylinder 208, and the output end of the second hydraulic cylinder 208 drives the movable plate 206 to move downward.

[0030] When sampling a product, it is usually necessary to manually open the outer packaging of the product and then sample the inside of the product, which not only wastes manpower but is also inefficient. The following provides a structure that can open the product packaging: Reference Figures 5 to 7 Specifically, the output end of the third hydraulic cylinder 402 is connected to a rolling wheel, and one side of the receiving plate 204 is connected to a pressing plate 404 corresponding to the output end of the third hydraulic cylinder 402. Both ends of the pressing plate 404 are tilted upwards, so that the rolling wheel at the output end of the third hydraulic cylinder 402 can move to the bottom of the pressing plate 404, thereby pressing down the output end of the third hydraulic cylinder 402. The telescopic cutter assembly 403 includes a fixed box 405 and a cutter support platform 406 located in the fixed box 405. An oil chamber 407 is provided inside the cutter support platform 406. The oil chamber 407 and the third hydraulic cylinder 402 are connected through an oil circuit, so that the hydraulic oil can move between the third hydraulic cylinder 402 and the oil chamber 407.
