Description

Technical Field

[0001] The present invention relates to the technical field of food detection, and in particular to a food detection device based on RFID technology and capable of detecting both raw and cooked food. Background Art

[0002] Food safety has become a global topic. Malicious food safety incidents continue to occur internationally, causing huge economic losses. Food safety issues mainly include the following aspects: chemical hazards, biological toxins, microbial hazards, food adulteration and the safety of genetically engineered foods.

[0003] The existing food testing equipment based on RFID technology has the following defects:

[0004] 1. Comparative document CN209327323U discloses a food inspection device, "including a frame, a conveyor belt, a bracket, a driven wheel and a driving wheel. Partition 1 and partition 2 are arranged at the central position of the front and rear sides of the conveyor belt. Cylinder 1 is arranged between partition 1 and partition 2. Cylinder 1 drives the piston rod to extend and retract. An electromagnet for grabbing food boxes is fixedly arranged at one end of the piston rod. A crossbeam is fixedly arranged on the inner wall of the rear side of the frame, and a food inspection machine is fixedly arranged on the crossbeam; the electromagnet grabs the food box containing bad food detected by the food inspection machine, and then the food box is conveyed to the receiving trough below through the hole. In addition, the food inspection probe is connected to the slider, and through the work of cylinder 2, it moves up and down with slider 2 to automatically inspect the food in the food box, effectively improving production efficiency. The device has a simple structure, a high degree of automation and strong practicality", but the device does not have a good raw and cooked detection structure, making it difficult to make a quick judgment on foods such as eggs or meat, so it has certain limitations in actual use;

[0005] 2. Comparative document CN212458916U discloses a detection device with food detection and sampling, "including a shell and a movable rod, a support plate is arranged inside the shell, and a mounting column is movably connected above the support plate, the movable rod is located above the mounting column, and a first connecting plate is arranged above the movable rod. Compared with the existing ordinary food detection equipment, the detection device with food detection and sampling has a detachable structure formed by the movable rod through the first connecting plate and the second connecting plate, and the movable rod forms a telescopic structure with the draw rod through the second connecting plate. The user can remove the movable rod from the second connecting plate through the first connecting plate, thereby improving the efficiency of replacing parts. At the same time, the user can adjust the length of the draw rod to adjust the length of the movable rod, so that it can rise or fall, thereby causing the support plate to rise and the sample to separate", but the device does not have a good food sampling detection structure, making it difficult for the staff to detect the food, thereby affecting the work quality;

[0006] 3. Comparative document CN109533592B discloses a sampling and storage device for powder food detection. "The box cover is located directly above the box body and is mutually engaged with the top of the box body. The transverse partition is transversely installed between the left and right inner walls of the box body. The middle isolation cylinder is installed in the middle position of the upper surface of the transverse partition and penetrates the transverse partition. The two inner cylinders are symmetrically installed on the inner side of the box body and fixedly connected to the upper surface of the transverse partition. The two soft storage mechanisms are respectively installed on the inner sides of the two inner cylinders. The two inner partition mechanisms are respectively installed on the inner sides of the two inner cylinders and are respectively connected to the outer sides of the corresponding soft storage mechanisms. The sampling and storage device for powder food detection reduces the space for the fine solid particles of powder food to diffuse under a bumpy state. The powder food sample can be extracted and exported without opening the box cover, thereby ensuring the accuracy of the detection of the components of the powder food sampling sample." However, the device does not have a good food preservation structure, making it difficult for the staff to provide a relatively good storage environment for the food, which can easily cause the food to be damaged;

[0007] 4. Comparative document CN207472804U discloses a food inspection device, "including an inspection chamber, a display screen, a conveyor belt, a control button, a motor, a control panel and a X-ray tube, wherein the X-ray tube is arranged at the inner top of the inspection chamber and is fixedly connected to the inspection chamber by bolts, wherein the X-ray tube includes an anode refractive surface and a filament, wherein the filament is arranged on the right side inside the X-ray tube, wherein the anode refractive surface is arranged on the left side inside the X-ray tube, and the refractive end of the anode refractive surface and the radiating end of the filament are arranged in the same horizontal plane and correspondingly. Detecting food by X-rays can remove a large amount of impurities in the food and increase the quality of the food. A protective curtain is provided to protect the staff who stay nearby for a long time and reduce the irradiation dose", but the raw and cooked detection structure of the device does not have a good disassembly structure, which makes it difficult for the staff to clean it, thus affecting the subsequent use.
