Abstract
Description
Technical Field
[0001] This utility model relates to the field of food testing and sampling technology, and in particular to a sampling device for food safety testing. Background Technology
[0002] In the field of food safety testing, it is crucial to ensure that food is free from harmful substances, heavy metals, and microbial contamination. The routine food safety testing process usually includes three steps: sample collection, processing, and analysis. Among these, the correct collection of samples is particularly important because the quality of the sample directly determines the validity of the subsequent test results.
[0003] Traditional manual sampling methods are often inefficient and susceptible to human error, failing to meet the requirements of high efficiency and high precision. Existing sampling devices are generally only suitable for solid or liquid foods and cannot handle both types of food sampling, resulting in low efficiency. Furthermore, some food residue remains inside the device after sampling, which is difficult to clean and affects the accuracy of subsequent sampling.
[0004] Therefore, to address the aforementioned issues of not being able to simultaneously sample solid or liquid foods and the difficulty in cleaning food residues inside the device, a sampling device for food safety testing can be designed. Utility Model Content
[0005] To overcome the problems of not being able to simultaneously sample solid or liquid food and food residue inside the device being difficult to clean.
[0006] The technical solution of this utility model is as follows: a sampling device for food safety testing, including a sampling cylinder and a storage cylinder; a rotating shaft is rotatably connected inside the sampling cylinder; a spiral blade is installed on the outside of the rotating shaft; a sampling port is opened on the lower outer surface of the sampling cylinder; it also includes a sealing component and a lifting guide component; a sealing component for blocking the sampling port is installed on the outside of the sampling cylinder; a lifting guide component is fixedly connected to the right end of the storage cylinder; the sealing component includes an upper annular guide rail and a lower annular guide rail; a sealing plate is slidably connected between the upper annular guide rail and the lower annular guide rail; the lifting guide component includes a fixed seat; a guide rod and an anti-detachment baffle are fixedly connected to the lower end of the fixed seat in sequence; a guide slider is slidably connected to the outside of the guide rod; a linkage rod extending into the storage cylinder is fixedly connected to the left end of the guide slider; a lifting plate is fixedly connected inside the linkage rod; a flexible scraper is fixedly connected to the outside of the lifting plate.
[0007] Preferably, the sealing plate between the upper and lower annular guide rails is rotated to expose the sampling port. The spiral blades are driven to rotate by the rotating shaft, and the sampling cylinder is inserted into the food to be sampled. The food enters the sampling cylinder through the sampling port. As the rotating shaft and spiral blades rotate, the food rises and is sent into the storage cylinder until the sampling is completed. The sealing plate is rotated again to cover the sampling port to ensure airtightness. Then the sample is discharged from the bottom of the storage cylinder. Finally, the guide slider on the outside of the guide rod between the fixed seat and the anti-detachment baffle is pulled down, which drives the linkage rod to move down synchronously. The flexible scraper on the outside of the lifting plate scrapes all the food inside the storage cylinder.
[0008] Preferably, the upper and lower annular guide rails are respectively located on the upper and lower sides of the sampling port; the arc length of the sealing plate is greater than the arc length of the sampling port, and the height of the sealing plate is greater than the height of the sampling port; a sealing strip is installed on the inner side of the sealing plate.
[0009] Preferably, a motor for driving the rotating shaft is installed at the upper end of the sampling cylinder; a sealing plug is engaged at the lower end of the sample storage cylinder.
[0010] Preferably, the flexible scraper is fitted to the inner wall of the sample storage cylinder; the outer surface of the sampling cylinder near the sample storage cylinder has a discharge port.
[0011] Preferably, the guide slider can slide a distance greater than the height of the sample storage cylinder on the outside of the guide rod.
[0012] Preferably, the lower end of the sample storage cylinder has a slot that matches the linkage rod.
[0013] The beneficial effects of this utility model are as follows: Based on the auger structure design, it facilitates uniform and continuous sampling of food, and can simultaneously handle both liquid and solid sampling, thus having a wider range of applications. It is also equipped with a cleaning mechanism, which scrapes off the residue attached to the inside after the sample is discharged, thereby ensuring the accuracy of the next sampling. Furthermore, by blocking the sampling port, the internal sealing of the device is ensured after sampling, preventing food samples from being contaminated. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figure 1 and Figure 3 In this embodiment, the upper annular guide rail 61 and the lower annular guide rail 62 are respectively disposed on the upper and lower sides of the sampling port 5; the arc length of the sealing plate 63 is greater than the arc length of the sampling port 5, and the height of the sealing plate 63 is greater than the height of the sampling port 5; a sealing strip is installed on the inner side of the sealing plate 63 to ensure the sealing effect of the sampling port 5, and to ensure the internal sealing after sampling to avoid sample contamination; a motor 11 for driving the rotating shaft 3 is installed at the upper end of the sampling cylinder 1; a sealing plug 12 is engaged at the lower end of the sample storage cylinder 2 to ensure the sealing of the sample storage cylinder 2 during sampling.
[0022] Please see Figure 1 and Figures 3-4In this embodiment, the flexible scraper 10 is fitted to the inner wall of the sample storage cylinder 2 to ensure the cleaning effect of the flexible scraper 10 on the inner wall of the sample storage cylinder 2; the outer surface of the sampling cylinder 1 near the sample storage cylinder 2 is provided with a discharge port; the guide slider 74 can slide a distance greater than the height of the sample storage cylinder 2 outside the guide rod 72; the lower end of the sample storage cylinder 2 is provided with a groove 13 that matches the linkage rod 8, which ensures the sealing of the sample storage cylinder 2 without affecting the extension of the linkage rod 8 into the sample storage cylinder 2.
[0023] During operation, the sealing plate 63 between the upper annular guide rail 61 and the lower annular guide rail 62 is rotated to expose the sampling port 5. The motor 11 is started to drive the rotating shaft 3 to rotate, and the spiral blade 4 rotates synchronously. The sampling cylinder 1 is inserted into the food to be sampled. The food enters the sampling cylinder 1 through the sampling port 5. As the rotating shaft 3 and the spiral blade 4 rotate, the food rises and is sent into the storage cylinder 2 until the sampling is completed. The sealing plate 63 is rotated again to cover the sampling port 5 to ensure sealing. Then the sealing plug 12 is removed and the sample is discharged from the bottom of the storage cylinder 2. Finally, the guide slider 74 on the outside of the guide rod 72 between the fixed seat 71 and the anti-detachment baffle 73 is pulled down, which drives the linkage rod 8 to move down synchronously.

Furthermore, by shielding the sampling port, the device's internal seal is ensured after sampling, preventing food sample contamination. This addresses the issues of not being able to simultaneously handle solid or liquid food sampling and the difficulty in cleaning food residues inside the device.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
