Description

Technical Field

[0001] This utility model relates to the field of food production testing, and in particular to a peroxide value analyzer for food production. Background Technology

[0002] Food production must be equipped with peroxide value meters because the oxidation and deterioration of oils and fats can exacerbate the risks associated with microorganisms, toxins, pesticide residues, heavy metals, and adulteration. The instrument can quantitatively measure rancidity on-site in 3 minutes, promptly intercepting spoiled raw materials, blocking the comprehensive hazards, and communicating with multi-indicator rapid testing data to build a closed-loop prevention and control system to ensure the authenticity and safety of food.

[0003] A search revealed a Chinese patent publication number: CN221224714U, which discloses a peroxide value measuring device. When the sealing cap is closed, the first pressure sensor at the top of the detection tank senses the pressure, and the indicator light turns off. The peroxide value measuring instrument can directly ignore scanning the detection tank, reducing energy consumption and increasing detection speed. When the operator opens the sealing cap, the first pressure sensor loses its sensing function, the indicator light turns on and illuminates red. When the reagent bottle is correctly inserted into the detection tank, the second pressure sensor at the bottom of the detection tank senses the pressure, and the indicator light illuminates green, increasing the accuracy of the device's detection work.

[0004] The above technical solutions ensure the accuracy of the detection operation through structures such as sealing caps and pressure sensors. However, when detecting solid or semi-solid foods, it is necessary to crush the food beforehand, which increases the operation steps and time costs. The transfer process is prone to sample loss or contamination, affecting the accuracy of weighing. Furthermore, samples exposed to air may cause deviations in the detection results due to oxidation. Therefore, a peroxide value analyzer for food production is proposed to solve the above problems. Utility Model Content

[0014] The rectangular groove is formed on the top outer wall of the weighing isolation plate.

[0015] As a further description of the above technical solution:

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3 This utility model provides an embodiment of a peroxide value analyzer for food production, comprising an analyzer body 1, a cover plate 2 hinged to the surface of the analyzer body 1, a detection groove 3 formed on the inner surface of the analyzer body 1, a display screen 4 fixedly connected to the top of the analyzer body 1, an installation groove 5 formed on the top of the analyzer body 1, a weighing sensor 6 fixedly connected to the inner wall of the installation groove 5, the weighing sensor 6 being a cantilever beam type weighing sensor 6, a weighing isolation plate 7 fixedly connected to the top of the weighing sensor 6, a crushing barrel 11 set on the top of the weighing isolation plate 7, the installation groove 5 being fitted onto the outer wall of the crushing barrel 11, allowing small pieces or small amounts of solid or semi-solid samples to be directly fed into the crushing barrel 11 for crushing, followed by direct weighing after crushing, and then... The corresponding amount of solvent is added to the weight for easy subsequent testing. The weight is automatically zeroed before each weighing, and the residual weight in the chamber needs to be deducted to ensure weighing accuracy. A sealing cap 12 is threadedly connected to the top outer wall of the crushing barrel 11. A small motor 13 is fixedly connected to the top of the sealing cap 12. A mounting shaft 14 is fixedly connected to the output end of the small motor 13. A spiral blade 15 is fixedly connected to the outer wall of the mounting shaft 14. The spiral blade 15 is conical and there are two sets. The upper spiral blade 15 is smaller than the lower spiral blade 15. The diameter of the uppermost end of the two sets of spiral blades 15 is smaller than the diameter of the lowermost end. A handle 16 is fixedly connected to the top of the sealing cap 12. An exhaust pipe 17 is fixedly connected to the inner wall of the sealing cap 12. An exhaust valve 18 is fixedly connected to the top of the exhaust pipe 17.

[0033] Reference Figures 3-4 The bottom of the crushing barrel 11 is provided with a splitting assembly, which includes a rectangular groove 8, a magnetic ring 9 and a rectangular block 10. There are four sets of splitting assemblies, which are arranged in a rectangular array around the center point of the crushing barrel 11. This allows the crushing barrel 11 to be quickly disassembled from the weighing isolation plate 7 for easy cleaning. The rectangular groove 8 is opened on the top outer wall of the weighing isolation plate 7. The inner wall of the rectangular groove 8 is fixedly connected to the magnetic ring 9, and the inner wall of the magnetic ring 9 is magnetically connected to the rectangular block 10.

[0034] Reference Figures 4-5The bottom outer wall of the exhaust pipe 17 is provided with a threaded groove 19, and the inner wall of the threaded groove 19 is threadedly connected to a threaded sleeve 20. The threaded sleeve 20 is fitted on the outer wall of the exhaust pipe 17, and a filter screen 21 is fixedly connected to the inner wall of the threaded sleeve 20. The filter screen 21 prevents the dust generated by crushing from overflowing. The filter screen 21 is located at the bottom end of the exhaust pipe 17. The circumferential surface of the threaded sleeve 20 is provided with a concave handle 22. Two sets of concave handles 22 are provided to increase the friction between the hand and the threaded sleeve 20 and ensure the anti-dislodgement force when screwed out or screwed in.

[0035] Working principle: The operator directly puts small pieces or small amounts of solid or semi-solid samples into the crushing chamber 11, and then closes the crushing chamber 11 tightly with the handle 16 at the top of the sealing cap 12 to ensure the chamber is sealed. After starting the small motor 13, its output end drives the mounting shaft 14 to rotate, and the two sets of conical spiral blades 15 rotate at high speed. The smaller spiral blade 15 at the upper end first cuts the sample, and the larger spiral blade 15 at the lower end further crushes it. The conical structure design allows the sample to gather to the bottom under the action of gravity, improving the uniformity of crushing. The gas generated during the crushing process can be discharged in a controlled manner through the exhaust pipe 17 on the inner wall of the sealing cap 12 and the exhaust valve 18 at the top, avoiding excessive pressure in the chamber. The filter screen 21 at the bottom of the exhaust pipe 17 can prevent dust from overflowing and keep the operating environment clean. The threaded sleeve 20 can be opened through the concave handle. Hand 22 is easy to disassemble and assemble, facilitating the cleaning and maintenance of filter screen 21. After crushing, the cantilever beam type weighing sensor 6 in the mounting slot 5 at the top of the measuring instrument body 1 is used for accurate weighing. Before weighing, the equipment is automatically zeroed, deducting the weight of the crushing barrel 11 and the residual weight in the chamber to ensure accurate weighing benchmark. The crushing barrel 11 is placed by aligning the four sets of rectangular blocks 10 at the bottom with the rectangular slot 8 at the top of the weighing isolation plate 7. The magnetic ring 9 in the rectangular slot 8 is magnetically attracted to the rectangular blocks 10, achieving quick positioning and installation. When cleaning is required, simply lift the crushing barrel 11 upwards to complete the disassembly. The operation is convenient. According to the sample weight measured by the weighing sensor 6, the operator adds the corresponding amount of solvent in proportion to prepare for subsequent peroxide value detection. The entire process, through crushing and weighing design, reduces sample transfer loss and improves detection efficiency and accuracy.
