Description

Technical Field

[0001] This application relates to the field of dairy product testing and sampling technology, specifically a sampling device for rapid testing of dairy products. Background Technology

[0002] In the dairy production process, the quality control process requires sampling and testing of raw materials and finished products in different physical states, including a variety of products such as liquid milk, high-viscosity cream and solid cheese.

[0003] An existing patent (publication number: CN218725742U) discloses a sampling device for dairy product testing, comprising two extraction cylinders fixedly mounted on a mounting plate. Each extraction cylinder has a piston plate slidably connected inside it, and each piston plate has a pull rod fixedly mounted on it. A pull plate is fixedly mounted at one end of each pull rod outside the extraction cylinders. An extraction seat is fixedly mounted at the lower end of each extraction cylinder, and a flexible tube is connected to each extraction seat. A movable seat is connected to the lower end of each flexible tube. A lifting mechanism is installed between each extraction cylinder and each movable seat. The advantages are: precise control of the sampling depth of dairy products can be achieved as needed, improving the accuracy of the test results to a certain extent; and simultaneous sampling at different depths of dairy products is possible, facilitating comparative testing and avoiding limitations in testing methods.

[0004] The above-mentioned sampling device can precisely control the sampling depth of dairy products as needed during use, which improves the accuracy of the test results to a certain extent. However, in the production process, dairy products include solid, liquid and viscous substances. However, during the sampling process, high-viscosity materials, such as cream, are prone to forming cavities at the front end of the extraction seat, causing sampling interruption or insufficient sample volume. For solid dairy products, sampling cannot be performed, and external tools are required to assist in sampling, resulting in insufficient operational continuity and inconvenience. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a sampling device for rapid testing of dairy products, which has the advantages of rapid sampling of various types of dairy products and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a sampling device for rapid testing of dairy products, comprising a sampling container and two sampling tubes, wherein a hinge seat is provided below the sampling container, the top ends of the two sampling tubes are hinged to the hinge seat, the bottom ends of the two sampling tubes are L-shaped, the bottom suction ends of the two sampling tubes are conical, and clamps are fixedly connected to the outer surfaces of the bottom ends of the two sampling tubes. The top of the sampling container is threadedly sealed with a sealing cap. The bottom of the sealing cap is fixedly connected to two connecting rods. The bottom of the two connecting rods is fixedly connected to a lifting plate. The lifting plate slides and inserts into the sealing cap, and the bottom of the lifting plate contacts the inner bottom wall of the sampling container.

[0007] Furthermore, a bracket is fixedly connected to the bottom of the sampling container, and the bracket is fixedly connected to both sides of the hinge seat.

[0008] The above solution, through the setting of the bracket, can achieve the purpose of connecting the sampling container and the hinge seat.

[0009] Furthermore, a release tube is fixedly connected to one side of the sampling container, and a valve is installed at one end of the release tube.

[0010] The above solution, through valves and release pipes, allows users to easily release the liquid dairy products inside the sampling container.

[0011] Furthermore, a pump body is installed between the sampling tank and the hinge seat. A three-way valve is provided below the input end of the pump body, and the output end of the three-way valve is fixedly connected to the input end of the pump body. The output end of the pump body is fixedly connected to the bottom of the sampling tank. Both input ends of the three-way valve are fixedly connected to bellows, and the other ends of the two bellows are fixedly connected to the top of the sampling tubes that are close to them.

[0012] The above scheme and settings enable simultaneous sampling by two sampling tubes, thereby improving sampling speed.

[0013] Furthermore, a storage box is provided on one side of the sampling container, and a handle is fixedly connected to one side of the storage box. The handle is slidably inserted into one side of the sampling container.

[0014] The above solution, with the storage box, makes it easy for users to place the solid dairy products they have picked up into the storage box for storage.

[0015] Furthermore, each of the sampling tubes is integrally formed.

[0016] By employing the above-mentioned method, the sampling tube is integrally molded, which ensures its mechanical strength and improves its bending resistance.

[0017] Furthermore, two symmetrically arranged grips are fixedly connected to the outer surface of the bracket.

[0018] The above solution, through the design of the grip bar, makes it easy for operators to hold the device stably for sampling operations. When the sampling tube moves along an S-shaped trajectory, it provides a stable force fulcrum, making it easy for both hands to work together to control the balance of the device.

[0019] Compared with the prior art, the technical solution of this application has the following beneficial effects: This sampling device for rapid testing of dairy products enables multi-scenario sampling of liquid, high-viscosity, and solid dairy products. Liquid dairy products can be directly extracted. Creamy materials move along the S-track of the device, continuously accumulating in the conical structure during the pushing process. This effectively avoids the cumbersome process of constantly re-inserting after the cavity is created in straight tube sampling, ensuring sampling continuity. Solid dairy products are physically clamped by the sampling tube driving the clamping plate to close, solving the problem of traditional devices relying on external tools to sample solid materials. This significantly improves operational continuity and sampling integrity. After opening the sealing cover, the lifting plate can move the sample with poor flowability upward as a whole, avoiding the residue of high-viscosity materials. For liquid dairy product shells, they can be directly discharged by opening the valve. The sliding insertion storage box can be separated from the sampling tank, facilitating the receipt of clamped solid dairy products and improving user convenience. The pump provides stable negative pressure, and the three-way valve distributes power to the double bellows, enabling the two sampling tubes to operate simultaneously and improving sampling efficiency.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] Please see Figure 1 , Figure 2 and Figure 3This embodiment of a sampling device for rapid testing of dairy products includes a sampling container 1 and two sampling tubes 2. A hinge seat 3 is provided at the bottom of the sampling container 1. The top ends of both sampling tubes 2 are hinged to the hinge seat 3. The bottom ends of both sampling tubes 2 are L-shaped, and the suction ends of both sampling tubes 2 are conical. Clamping plates 4 are fixedly connected to the outer surfaces of the bottom ends of both sampling tubes 2. When sampling emulsions, the sampling tubes 2 can be inserted directly into the emulsion for extraction. When sampling cream-type dairy products with poor flowability, the sampling tubes are moved during the sampling process. 2. Moving along an S-shaped trajectory, it can continuously push dairy products to the conical structure of sampling tube 2, ensuring continuous sampling. The tops of the two sampling tubes 2 are hinged to the hinge seat 3. For fixed dairy products, the bottom clamps 4 of the two sampling tubes 2 can be brought close to each other to clamp and sample solid dairy products. Each sampling tube 2 is integrally formed. The two sampling tubes 2 are made of food-grade stainless steel, which can effectively avoid contaminating the sample in the container during sampling. The integral forming of the sampling tubes 2 can ensure the mechanical strength of the sampling tubes 2 and improve their bending resistance.

[0024] Please see Figure 1 , Figure 2 and Figure 3 A bracket 8 is fixedly connected to the bottom of the sampling tank 1. The bracket 8 is fixedly connected to both sides of the hinge seat 3. The bracket 8 enables the connection between the sampling tank 1 and the hinge seat 3. A pump body 11 is installed between the sampling tank 1 and the hinge seat 3. A three-way valve 12 is installed below the input end of the pump body 11, and the output end of the three-way valve 12 is fixedly connected to the input end of the pump body 11. The output end of the pump body 11 is fixedly connected to the bottom of the sampling tank 1. Both input ends of the three-way valve 12 are fixedly connected to bellows 13. The other ends of the two bellows 13 are fixedly connected to the top ends of the sampling tubes 2 that are close to each other. Through the above settings, the two sampling tubes 2 can be sampled at the same time, thereby improving the sampling speed.

[0025] Please see Figure 1 , Figure 3 and Figure 4Two symmetrically arranged grips 16 are fixedly connected to the outer surface of the support 8. The grips 16 facilitate stable gripping of the device by the operator for sampling operations. They provide a stable fulcrum when the sampling tube 2 moves along an S-shaped trajectory, facilitating coordinated control of the device's balance. A sealing cap 5 is threadedly connected to the top of the sampling container 1. Two connecting rods 6 are fixedly connected to the bottom of the sealing cap 5, and a lifting plate 7 is fixedly connected to the bottom of the two connecting rods 6. The lifting plate 7 slides vertically into the sealing cap 5, and its bottom contacts the inner bottom wall of the sampling container 1. This design allows for the handling of dairy products with poor flowability. For products like cream, the sample can be moved upwards by opening the sealing cap 5 and lifting the lifting plate 7. For viscous dairy products, it can be poured directly. A release tube 9 is fixedly connected to one side of the sampling container 1, and a valve 10 is installed at one end of the release tube 9. Through the valve 10 and the release tube 9, the user can easily release the liquid dairy products inside the sampling container 1. A storage box 14 is provided on one side of the sampling container 1, and a handle 15 is fixedly connected to one side of the storage box 14. The handle 15 slides up and down into the side of the sampling container 1. The storage box 14 makes it easy for the user to put the solid dairy products they have picked up into the storage box 14 for storage.

[0026] It should be noted that the lifting plate 7 and the pump body 11 are slidably connected at the discharge end. Because cream has poor fluidity, when lifting, the cream will not fall from the through hole at the connection point into the bottom of the lifting plate 7.

[0027] The working principle of the above embodiment is as follows: The operator holds the handles 16 on both sides of the bracket 8 with both hands and inserts the device vertically into the dairy product container. The horizontal section of the L-shaped structure at the bottom of the sampling tube 2 first contacts the material surface, and the conical suction end faces the inner wall of the container. The pump body 11 is started, and the three-way valve 12 is switched to the dual-channel connection state. The pump body 11 applies negative pressure to the two sampling tubes 2 through the bellows 13. The liquid dairy product enters the sampling tube 2 along the conical suction end, and is finally transported to the sampling tank 1 through the bellows 13, the three-way valve 12, and the pump body 11. During the sampling process, the sampling tube 2 remains stationary, and the liquid sample is directly extracted by relying on negative pressure. This method is suitable for high viscosity samples. When sampling materials, the sampling tube 2 is manually controlled to swing back and forth in an S-shaped trajectory. At this time, the L-shaped structure at the bottom of the sampling tube 2 continuously gathers the surrounding materials to the conical suction end through the lateral pushing action. The pump body 11 runs synchronously to ensure that viscous materials are continuously sucked into the sampling tank 1. For sampling solid dairy products, the tops of the two sampling tubes 2 are pinched to control their opening and closing angle, so that the bottom clamping plate 4 gradually approaches and clamps the solid sample. The anti-slip texture on the inner wall of the clamping plate 4 enhances the friction and ensures that the sample is completely clamped. The sliding insertion storage box 14 is disassembled to receive the sample. The independent handle 15 of the storage box 14 is designed to facilitate the quick transfer of the sample to the testing area.
