Description

Technical Field

[0001] The utility model relates to the technical field of soy sauce sampling inspection devices, in particular to a sampling inspection device for soy sauce production. Background Art

[0002] Soy sauce, known for its excellent flavor, is a common condiment used in cooking. It's made from fermented soybeans, black beans, wheat, or bran. The quality of soy sauce depends on factors such as the temperature, environment, and light during fermentation, so regular sampling and inspection are necessary to ensure its quality.

[0003] CN219224238U discloses a sampling device for soy sauce, which filters the soy sauce into a filter cartridge and then immerses a sampling tube in the soy sauce to collect the soy sauce. Although the device can filter soybean meal, oil stains and oil droplets remain on the outer wall of the sampling tube after the soy sauce is collected. Not only will the hands be contaminated when the sampling tube is removed, but the outer wall of the sampling tube needs to be cleaned before the sample is sent for inspection, which is very inconvenient. Utility Model Content

[0004] In order to solve the technical problems existing in the above background technology, the utility model provides a random inspection device for soy sauce production.

[0005] The technical solution of this utility model is as follows:

[0006] A sampling inspection device for soy sauce production includes a filter cartridge and a handle connected to the outer wall of the filter cartridge. A placement seat is provided in the filter cartridge, and a test tube slot with an upward opening is vertically opened in the placement seat for vertically accommodating a test tube.

[0007] The sealing cover further comprises a sealing cover having a leakage hole in the middle thereof, a positioning ring extending downward from the lower edge of the leakage hole, the positioning ring being capable of being inserted into the test tube, a sealing portion protruding downward from the bottom surface of the sealing cover, the sealing portion surrounding the positioning ring, the outer side of which is adapted to the opening of the test tube slot;

[0008] The top surface of the sealing cover is lower than the top edge of the filter cartridge.

[0009] When the sampling inspection device is used, the test tube is placed vertically in the test tube slot with the opening facing upwards, the positioning ring of the sealing cover is inserted into the test tube, and the sealing cover is placed downward on the test tube slot to seal the test tube slot.

[0010] During random inspection, press the filter cartridge downward from the surface of the soybean meal to allow the soy sauce to enter the filter cartridge. When the soy sauce covers the top surface of the sealing cover, it enters the test tube from the leakage hole. When the test tube is filled with an appropriate amount of soy sauce, the random inspection device can be removed and the test tube can be taken out. Since the sealing cover and the test tube groove are sealed, the soy sauce is prevented from entering the space between the outer wall of the test tube and the side wall of the test tube groove, which also prevents the outer wall of the test tube from being stained with oil stains and oil droplets.

[0011] In the present application, the placement seat is fixed at the center of the bottom wall of the filter cartridge so that the soy sauce can enter the test tube from all sides thereof.

[0012] However, the test tube groove is preferably a cylindrical blind hole, and the diameter of the blind hole is larger than the diameter of the test tube.

[0013] In addition, in order to stabilize the test tube in the test tube slot, at least two test tube clamps are provided in the test tube slot. The at least two test tube clamps are located in the same cross section and jointly clamp and fix the test tube.

[0014] Preferably, there are three test tube clamps evenly distributed along the circumference of the test tube slot.

[0015] Furthermore, one end of the test tube clamp extends into the test tube groove and is provided with a clamping portion at the end, and the other end is inserted into the placement seat along the radial direction of the test tube groove and is connected to the placement seat through an elastic member.

[0016] In order to hold the test tube more firmly, the clamping portion is a laterally extending arc-shaped plate with the concave surface facing the central axis of the test tube groove.

[0017] In order to make it easier for the soy sauce to flow into the test tube, the leakage hole is preferably an inverted tapered hole.

[0018] In addition, to facilitate insertion and removal of the sealing cover, a handle is provided on the sealing cover. The handle is in an inverted U-shape, with both ends facing downward and connected to the sides of the sealing cover at symmetrical positions. This also prevents soy sauce from covering the top of the handle, thus preventing injuries from getting stained by soy sauce when using the product.

[0019] In addition, in order to ensure the sealing of the space between the outer wall of the test tube and the side wall of the test tube groove, a sealing ring is further provided on the outer surface of the sealing portion.

[0020] The utility model provides a sampling inspection device for soy sauce production. A test tube is sealed in a test tube groove by a sealing cover, and soy sauce is directly introduced into the test tube through a leak hole and a positioning ring, thereby preventing the soy sauce from entering between the outer wall of the test tube and the side wall of the test tube groove, and ensuring that the outer wall of the test tube is clean and tidy.

[0023] The components represented by the reference numerals in the figure are:

[0024] 1. Filter cartridge; 11. Placement seat; 12. Test tube slot; 13. Sealing cover; 131. Leak hole; 132. Positioning ring; 133. Sealing part; 134. Handle; 14. Test tube clamp; 2. Handle; 3. Test tube. DETAILED DESCRIPTION

[0025] like Figure 1As shown, the present invention provides a sampling inspection device for soy sauce production, comprising a filter cartridge 1 and a handle 2 connected to the outer wall of the filter cartridge 1. The grip portion of the handle 2 is positioned away from the filter cartridge 1 to facilitate insertion of the filter cartridge 1 into a fermentation tank or vat. A receiving seat 11 is provided within the filter cartridge 1. A test tube slot 12 is vertically defined within the receiving seat 11, with an upwardly facing opening, for vertically accommodating a test tube 3.

[0026] In this embodiment, the placement seat 11 is fixed at the center of the bottom wall of the filter cartridge 1 , and its height is smaller than the depth of the filter cartridge 1 , so that the soy sauce can enter the test tube 3 from all sides thereof.

[0027] The cross section of the test tube slot 12 can be rectangular, circular or other shapes, and its size is larger than the diameter of the test tube 3. In this embodiment, the test tube slot 12 is preferably a cylindrical blind hole.

[0028] A sealing cover 13 is provided on the top of the placement seat 11 , a leakage hole 131 is provided in the middle of the sealing cover 13 , a positioning ring 132 extends downward from the lower edge of the leakage hole 131 , and the diameter of the positioning ring 132 is smaller than the inner diameter of the test tube 3 and can be inserted into the test tube 3 .

[0029] A sealing portion 133 protrudes downward from the bottom surface of the sealing cover 13. The sealing portion 133 surrounds the positioning ring 132, and its outer surface fits into the opening of the test tube slot 12. When the sealing cover 13 is placed on the placement seat 11, the sealing portion 133 is inserted into the test tube slot 12 to seal the test tube slot 12. The top surface of the sealing cover 13 is lower than the top edge of the filter cartridge 1.

[0030] In order to facilitate the flow of soy sauce into the test tube 3, the leakage hole 131 is preferably an inverted tapered hole.

[0031] When the sampling inspection device is in use, the test tube 3 is placed vertically in the test tube slot 12 with the opening facing upward. The positioning ring 132 of the sealing cover 13 is aligned with the test tube 3 and inserted into the test tube slot 12. The sealing portion 133 is inserted closely against the side wall of the test tube slot 12. The side wall of the test tube 3 at the opening is located between the sealing portion 133 and the positioning ring 132. As the sealing cover 13 is lowered and covered on the test tube slot 12, the test tube slot 12 is sealed.

[0032] During random inspection, filter cartridge 1 is pressed downward from the surface of the soybean meal, allowing soy sauce to enter filter cartridge 1 through the filter holes. When the soy sauce covers the top surface of sealing cap 13, it enters test tube 3 through leakage hole 131. Once the test tube 3 has been loaded with an appropriate amount of soy sauce, the random inspection device can be removed, sealing cap 13 opened, and test tube 3 taken out. Because sealing cap 13 seals test tube slot 12, soy sauce is prevented from entering the space between the outer wall of test tube 3 and the sidewall of test tube slot 12, thus preventing oil stains and oil droplets from forming on the outer wall of test tube 3.

[0033] In this embodiment, to facilitate the removal and placement of the test tube 3, when the test tube 3 is sealed in the test tube slot 12, the top of the test tube 3 is higher than the top of the test tube slot 12. A corresponding recess is formed on the bottom surface of the sealing cover 13 between the sealing portion 133 and the positioning ring 132. When the sealing cover 13 is placed on the test tube slot 12, the top of the test tube 3 is located in the recess.

[0034] Preferably, when the sealing cover 13 is placed on the test tube groove 12 , the top edge of the test tube 3 contacts the bottom surface of the trough to prevent excessive soy sauce from entering the test tube groove 12 from the top of the test tube 3 .

[0035] In this embodiment, the length of the positioning ring 132 is preferably greater than the length of the positioning portion, so that the positioning ring 132 can be inserted into the test tube 3 first and then aligned with the opening position of the test tube slot 12, avoiding the inconvenience of aligning the test tube 3 and the test tube slot 12 at the same time.

[0036] Furthermore, to stably accommodate the test tube 3 within the test tube slot 12, at least two test tube clamps 14 are provided within the test tube slot 12. One end of each clamp 14 extends into the test tube slot 12 and is provided with a clamping portion. The other end of each clamp 14 is radially inserted into the placement seat 11 along the test tube slot 12 and connected to the placement seat 11 via an elastic member. At least two test tube clamps 14 are located within the same cross-section and jointly clamp and secure the test tube 3.

[0037] When placing the test tube 3, the test tube 3 opens the test tube clamp 14, and the test tube clamp 14 clamps the test tube 3 to ensure that it is stably upright in the test tube groove 12, which facilitates the alignment and insertion of the positioning ring 132 of the sealing cover 13, and also prevents the test tube 3 from tilting and spilling soy sauce after opening the sealing cover 13.

[0038] Preferably, the test tube clamps 14 include three and are evenly distributed along the circumference of the test tube groove 12 to make the clamping more stable.

[0039] Furthermore, in order to more firmly clamp the test tube 3 , the clamping portion is a transverse arc-shaped plate, with the concave surface facing the central axis of the test tube groove 12 .

[0040] In addition, to facilitate insertion and removal of the sealing cover 13, a handle 134 is provided on the sealing cover 13. The handle 134 is in an inverted U-shape, with both ends facing downward and connected to symmetrical positions on the sides of the sealing cover 13. At the same time, the soy sauce does not cover the top of the handle 134, thus preventing soy sauce from getting on your hands during use.

[0041] In addition, in order to ensure the sealing of the space between the outer wall of the test tube 3 and the side wall of the test tube groove 12, a sealing ring (not shown in the figure) is further provided on the outer surface of the sealing portion 133.
