Description

Technical Field

[0001] The utility model relates to the technical field of food samplers, in particular to a rapid sampler for food raw material detection. Background Art

[0002] The food sampling standards and specifications mainly involve national food safety standards and food production and sales. These standards usually cover the limit regulations for pathogenic microorganisms, pesticide residues, veterinary drug residues, heavy metals, pollutants, etc. in food. Therefore, it is essential to sample and test food raw materials. The most representative of food raw material testing is the sampling and testing of various granular or powdered grains. When sampling stacked grain materials, it is necessary to sample the upper, middle and lower layers of samples at different positions respectively, and mix them to prepare the most representative samples; the samplers in the prior art are mostly simple sampling shovels or sampling cylinders, and the following disadvantages are generally present during sampling: 1. Each sampling can only obtain samples of a single position and a single layer. To obtain a representative sample, sampling must be performed dozens of times or even dozens of times, and the sampling efficiency is low; 2. Sampling too many times is prone to process record errors, forgetting the sampling position, etc., resulting in poor sample representativeness. Utility Model Content

[0020] In the figure, there are an outer tube 1, an outer sampling port 2, an inner tube 3, an inner sampling port 4, a limit groove 5, a limit plate 6, a slide bar 7, a magnet sheet 8, a material guide plate 9, and a handle 10. DETAILED DESCRIPTION

[0021] like Figure 1 and Figure 2As shown, a rapid sampler for food raw material detection comprises an outer tube 1 with an opening at the top, the bottom end of the outer tube 1 is a pointed cone, a plurality of outer sampling ports 2 are uniformly distributed along the length direction on the outer tube 1, an inner tube 3 with an opening at the top is slidably connected in the outer tube 1, a plurality of inner sampling ports 4 matching the outer sampling ports 2 are opened on the inner tube 3, a limiting groove 5 is opened on the top of the outer tube 1, a sliding rod 7 is connected to the inner tube 3, and the sliding rod 7 is slidably connected to the limiting groove 5 up and down, when the outer sampling port 2 and the inner sampling port 4 coincide, the outer sampling port 2 is in an open state, and when the outer sampling port 2 and the inner sampling port 4 are misaligned, the outer sampling port 2 is blocked by the inner tube 3.

[0022] like Figure 3 As shown, a limit plate 6 is connected to the upper and lower ends of the limit groove 5, and a magnet sheet 8 is installed at the inner end of the limit plate 6. The magnet sheet 8 magnetically attracts the slide bar 7, and the magnet sheet 8 is used for braking the slide bar 7 at the upper and lower limit positions. The slide bar 7 is connected to the inner tube 3 by bolts; the cross-sections of the outer tube 1 and the inner tube 3 are square or circular; the outer tube 1 and the inner tube 3 are both made of stainless steel; and a handle 10 is installed on the outer tube 1.

[0023] like Figure 4 As shown, in order to ensure that the material falls smoothly into the inner tube 3 during sampling, a material guide plate 9 is installed at the bottom end of the outer sampling port 2 in an upward tilt; the angle between the material guide plate 9 and the vertical direction is 35°.

[0024] It should be noted that the utility model is mainly used for bulk grain materials (various rice, flour, beans, etc.) piled up in sales counters and material troughs in supermarkets and other places. Before sampling, ensure that the slide bar 7 is located at the upper limit position of the limit slot 5. At this time, the outer sampling port 2 is blocked by the inner tube 3 and is in a closed state. When sampling, the utility model is inserted into the pile of materials, and then the slide bar 7 is pushed to the lower limit position of the limit slot 5. At this time, the outer sampling port 2 and the inner sampling port 4 coincide with each other, and the outer sampling port 2 is in an open state. The material enters the inner tube 3 through the outer sampling port 2 and the inner sampling port 4, that is, multi-layer sampling is completed at one time. After sampling, the outer sampling port 2 is closed and the utility model is pulled out. Shaking the utility model can mix the sample materials in different layers. Finally, inverting the utility model can take out the sample.
