Description

Technical Field

[0001] This utility model relates to the field of food testing technology, and in particular to a device for separating impurities from food samples. Background Technology

[0002] Food testing is a discipline that studies and evaluates the quality and changes of food. Based on fundamental theories of physics, chemistry, and biochemistry, and various technologies, it inspects the quality of food raw materials, auxiliary materials, semi-finished products, finished products, and by-products according to established technical standards to ensure product quality. Food testing includes sensory evaluation, detection of nutrients, additives, and harmful substances. When testing peanuts, the focus is usually on roasted peanuts. Peanuts are typically heated indirectly with iron sand during processing. Current methods for testing roasted peanuts involve separating the peanuts from the sand and other impurities used in the roasting process before testing. However, during this separation, broken peanuts are often separated along with the sand, requiring a second process to remove the broken peanuts from the iron sand.

[0003] During filtration, iron sand needs to be placed inside the filter structure for filtration. After screening, the iron sand needs to be removed from the filter structure, as it is relatively small and difficult to remove. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in related technologies. Therefore, one objective of this utility model is to provide a food sample impurity separation device. The device's housing contains a filtration mechanism. Its core structure consists of two fixed frames with filter screens mounted on them, which are rotatably connected to a lifting threaded plate. During filtration, the tilt angle of the filter screens can be flexibly adjusted by driving the lifting threaded plate to rise and fall, thus efficiently completing the filtration operation. When it is necessary to remove iron filings, the operation is even more convenient; simply raise the lifting threaded plate, remove the disassembly plate, and the iron filings will automatically slide into the storage tank along the inclined surfaces of the filter screens and fixed frames, eliminating the need for additional cumbersome operations.

[0005] The food sample impurity separation device proposed by this utility model includes a box body, with storage slots fixedly connected to the upper ends of both sides of the box body, a motor fixedly connected to the lower outer wall of the box body, and a lifting screw fixedly connected to the output end of the motor.

[0006] A filter mechanism is installed on the lifting screw. The filter mechanism includes a lifting threaded plate, which is sleeved and threadedly connected to the lifting screw. Fixed frames are rotatably connected to both sides of the lifting threaded plate. Two sliding blocks are symmetrically rotatably connected to one side of the fixed frame. A filter screen is fixedly connected to the middle of the fixed frame. A surrounding plate is fixedly connected to the upper end of the fixed frame. A disassembly plate is snapped onto one side of the surrounding plate.

[0007] Preferably, the upper end of the lifting threaded plate is symmetrically fixedly connected with two positioning plates, which are slidably connected to the outer wall of the box.

[0008] Preferably, the enclosure has a U-shaped structure and is disposed on the outside of the corresponding filter screen.

[0009] Preferably, a slider is fixedly connected to the lower end of the slide block, and the slider has an L-shaped structure and is slidably connected to the upper end of the housing.

[0010] Preferably, an isolation plate is fixedly connected to the lower inner wall of the housing, and the lifting screw passes through and is rotatably connected to the isolation plate.

[0011] Preferably, two discharge ports are symmetrically opened at the top and bottom of each side of the box, and the upper discharge port is connected to the corresponding storage slot.

[0012] The beneficial effects of this utility model are:

[0013] (1) The box of this utility model is equipped with a filter mechanism. Its core structure is that two fixed frames with filter screens are connected to the lifting threaded plate in a rotating manner. During the filtration operation, the tilt angle of the filter screen can be flexibly adjusted by driving the lifting threaded plate to lift and lower, so as to efficiently complete the filtration operation. When it is necessary to remove the iron sand, the operation is more convenient. Just lift the lifting threaded plate and remove the disassembly plate. The iron sand will automatically slide into the storage slot along the inclined surface of the filter screen and the fixed frame without any extra complicated operation.

[0014] (2) After removing the iron sand, simply reinstall the disassembly plate and lower the lifting threaded plate to perform the filtration operation again. The entire process does not require complex adjustments or reassembly of the device. The operation process is simple and smooth, and continuous filtration can be achieved quickly, which greatly improves the working efficiency of the equipment. It is especially suitable for batch processing of food sample impurity separation scenarios.

[0015] (3) The U-shaped structure of the enclosure and the disassembly plate of this utility model can effectively block iron sand during the filtration process and prevent it from sliding off the edge of the fixed frame, thus ensuring the smooth progress of the filtration work. When unloading, removing the disassembly plate can provide a smooth sliding channel for the iron sand. This structural design takes into account both the leak prevention during filtration and the convenience during unloading. Attached Figure Description

[0023] Reference Figure 1-6 A food sample impurity separation device includes a box 1, with storage slots 6 fixedly connected to the upper ends of both sides inside the box 1, a motor 3 fixedly connected to the lower outer wall of the box 1, and a lifting screw 4 fixedly connected to the output end of the motor 3.

[0024] A filter mechanism 5 is installed on the lifting screw 4. The filter mechanism 5 includes a lifting threaded plate 51, which is sleeved and threadedly connected to the lifting screw 4. Two positioning plates 58 are symmetrically fixedly connected to the upper end of the lifting threaded plate 51. The positioning plates 58 are slidably connected to the outer wall of the housing 1. Fixed frames 52 are rotatably connected to both sides of the lifting threaded plate 51. Two sliding blocks 53 are symmetrically rotatably connected to one side of the fixed frame 52. A slider 54 is fixedly connected to the lower end of the slider 53. The slider 54 has an L-shaped structure and is slidably connected to the upper end of the housing 1. A filter screen 55 is fixedly connected to the middle of the fixed frame 52. A surrounding plate 56 is fixedly connected to the upper end of the fixed frame 52. A disassembly plate 57 is snapped onto one side of the surrounding plate 56.

[0025] An isolation plate 2 is fixedly connected to the lower inner wall of the box 1. The lifting screw 4 passes through and is rotatably connected to the isolation plate 2, which can protect the connection between the lifting screw 4 and the box 1, and prevent broken peanuts from getting stuck at the connection between the lifting screw 4 and the box 1. Two discharge ports are symmetrically opened at the upper and lower ends on both sides of the box 1, and the upper discharge port is connected to the corresponding storage tank 6. During use, iron sand and broken peanuts can be collected separately. The surrounding plate 56 has a U-shaped structure and is set outside the corresponding filter screen 55, which can block the iron sand at the upper end of the filter screen 55 and prevent the iron sand from slipping into the fixing frame 52 during filtration.

[0026] When using this device, connect the power supply, pour the iron sand to be filtered onto the filter screen 55, start the motor 3, the motor 3 drives the lifting screw 4 to rotate, the lifting screw 4 drives the lifting threaded plate 51 to rise and fall. During this process, the positioning plate 58 will slide on the outer wall of the housing 1 to prevent the lifting threaded plate 51 from shaking. The fixing frame 52 rotates on the lifting threaded plate 51. The side of the fixing frame 52 connected to the lifting threaded plate 51 rises and falls continuously, while the other side pushes the slide block 53 and the slider 54 to slide on the upper end of the housing 1. 4. While sliding, the slide block 53 will not detach from the box 1, and the iron sand will slide back and forth on the surface of the filter screen 55. The crushed peanuts will pass through the filter screen 55 and fall into the lower part of the box 1 for filtration. When the filtered iron sand is removed, the lifting threaded plate 51 and the disassembly plate 57 can be raised. The iron sand will slide along the filter screen 55 and the fixed frame 52 into the storage tank 6 and slide out of the box 1. Then the disassembly plate 57 can be reinstalled, the lifting threaded plate 51 can be lowered, and the iron sand to be filtered can be poured on to continue the filtration.
