Description

Technical Field

[0001] The present invention relates to the field of food detection, and in particular to a food auxiliary detection device. Background Art

[0002] Nitrite has a special inhibitory effect on Clostridium botulinum. In order to prevent the harm of botulinum toxin and inhibit botulinum, it is necessary to add nitrite appropriately to some meat products and bean products for preservation. In the process of marinating marinated meat, an appropriate amount of nitrite is added in the prior art. However, some unscrupulous merchants add excessive nitrite to further improve the antiseptic effect, which can lead to esophageal cancer and gastric cancer, and can cause nitrite food poisoning. Therefore, in the prior art, it is generally sampled and tested;

[0003] In the existing detection method, a certain amount of meat is sampled first, and then it is broken into small pieces by a crushing device, and then an appropriate amount of pure water is added. It is left to stand for about ten minutes until the water completely immerses the meat. At this time, the upper clear liquid is taken and nitrite detection reagent a and nitrite detection reagent b are added. Then, after shaking well, wait for 5-10 minutes to observe the color of the water, and use a colorimetric card for colorimetry to determine whether the nitrite exceeds the standard. In this way, during the entire detection process, the staff needs to perform multiple operations, and each operation needs to ensure the amount of liquid added. The whole process is time-consuming and labor-intensive, so how to operate conveniently needs to be considered. Summary of the invention

It should be noted that the stiffness coefficients of the second spring 47 and the plurality of first springs 37 are relatively large, and the stiffness coefficient of the second spring 47 is 5-6 times that of the stiffness coefficient of the first spring 37.

[0038] As an embodiment of the present invention, it also includes a detection mechanism, which is used to detect the sample liquid to be detected. The detection mechanism includes four transparent observation tubes 26 that penetrate the top plate 3, and the inner bottom of each transparent observation tube 26 is provided with a drainage port 19, and a manual valve is installed on the drainage port 19. Four reagent kits 25 are fixedly connected to the upper end of the top plate 3, and each reagent kit 25 is provided with two reagent storage tanks 29, and the two reagent storage tanks 29 respectively store nitrite detection reagent a and nitrite detection reagent b. Each reagent storage tank 29 is provided with an inclined negative pressure pipe 31, and the other ends of each two matching inclined negative pressure pipes 31 are commonly connected to a vertical pipe 30, and each transfer pipe 21 is connected to a drainage pipe 27, and the other end of each drainage pipe 27 extends to the inside of the corresponding transparent observation tube 26, and the upper end of each vertical pipe 30 is connected to the corresponding drainage pipe 27. The drainage pipe 27 is located at one end of the transparent observation tube 26 and is installed with a check valve to prevent water backflow;

[0039] As an embodiment of the present invention, each discharge pipe 27 is equipped with a normally closed solenoid valve on one side close to the corresponding transfer pipe 21, and each vertical pipe 30 is equipped with a one-way valve and a second normally open solenoid valve. The flow direction of the one-way valve in each vertical pipe 30 is from bottom to top. Each first piston plate 35 is conductive. A conductive strip 36 is provided on the top and bottom of the space on one side of each booster cylinder 24 close to the corresponding immersion cylinder 15. The first piston plate 35 and the corresponding two conductive strips 36 constitute an energized component. Each energized component is electrically connected to the corresponding second normally open solenoid valve, and also includes an external power supply. Multiple energized components and the corresponding second normally open solenoid valve constitute an electrical device. Multiple electrical devices are connected in parallel to the external power supply. That is, when the energized component is energized, the corresponding second normally open solenoid valve will be energized and closed.

[0040] In the present invention, when it is used, the staff first samples four pieces of braised meat of equal weight, and then places them in the annular groove 14, and directly below the four soaking cylinders 15, and then starts the multiple hydraulic telescopic rods 13 to contract, so that the connecting ring 9 can move up. The upward movement of the connecting ring 9 can make the inner bottom of the annular groove 14 abut against the lower end of the soaking cylinder 15, completing the bottom sealing, and then starts the motor 5 to rotate;

[0041] After the motor 5 is started, it will rotate the plurality of second gears 8 through the first gear 6, thereby rotating the plurality of first rotating tubes 7. The rotation of the plurality of first rotating tubes 7 will rotate the plurality of crushing blades 34 through the second rotating tubes 32 and the L-shaped rod 33, thereby crushing the flesh. In this process, the motor 5 will also rotate the rotating disk 16. The rotation of the rotating disk 16 can reciprocate the second piston block 48 left and right through the connecting strip 18. The second piston block 48 moves leftward to replenish gas from the outside through the cylinder intake pipe 40, and moves rightward through the exhaust pipe 4 1 The gas is pressed into the bottom space of the gas storage cylinder body 10. Since the first normally open electromagnetic valve in the release port 42 is powered on and closed at this time, the gas gathers at the bottom of the gas storage cylinder body 10, and then pushes the fourth piston block 46 to move upward. After the fourth piston block 46 moves upward, it will compress the second spring 47, and at the same time, multiple piston rods 45 are used to make multiple third piston blocks 44 move upward. The upward movement of the third piston blocks 44 will replenish water through the water inlet pipe 12, and at the same time, the air inlet pipe 49 is used to replenish gas, that is, the upper layer of the inner bottom space of the piston cylinder 23 is gas, and the lower layer is water;

[0042] When the staff turns off the motor 5, the flesh is crushed, the first normally open solenoid valve in the release port 42 is powered off and opened, and under the elastic action of the second spring 47, the fourth piston block 46 moves downward, and multiple third piston blocks 44 move downward. Taking the downward movement of one of the third piston blocks 44 as an example, in the early stage of the downward movement, the water is first squeezed out, and then enters the transfer pipe 21 through the drain pipe 28, and finally enters the soaking cylinder 15 along the first rotating tube 7 and the second rotating tube 32, and the air inside the soaking cylinder 15 is squeezed by the water and compressed, and the corresponding first piston plate 35 moves away from the soaking cylinder 15, and the first spring 37 is compressed. When the water in the piston cylinder 23 is completely squeezed After that, the height of the water in the soaking cylinder 15 is about 2 cm higher than the lower end of the second rotating tube 32, that is, the lower end of the second rotating tube 32 is located in the middle and upper part of the water. At this time, the gas begins to be released, and the gas enters the transfer tube 21 through the drain pipe 28, and finally enters the soaking cylinder 15 along the first rotating tube 7 and the second rotating tube 32. In this process, the gas can make all the residual water inside the multiple tubes be pressed out to avoid affecting the subsequent detection. At this time, the soaking work starts. In this state, the inner top space of the soaking cylinder 15 is high-pressure air. The high-pressure air will give pressure to the water, making it easier for the water to completely immerse into the flesh, thereby improving the actual soaking speed and optimizing the overall detection efficiency.

[0043] After the detection is completed, the normally closed solenoid valves in the multiple drainage pipes 27 are opened (in practice, the normally closed solenoid valves can be opened for a period of time after the motor 5 is turned off through automatic control by PLC). At this time, under the pressure of the high-pressure gas at the top of the immersion cylinder 15, the water body will be pressed into the second rotating tube 32, and finally enter the transparent observation tube 26 along the first rotating tube 7 and the drainage pipe 27 to achieve the sampling of the upper clear liquid. During the drainage process, when the water body passes through the drainage pipe 27, a faster flow rate will produce a lower pressure. The negative pressure is used to draw the nitrite detection reagent a and the nitrite detection reagent b into the drainage pipe 27 through the vertical pipe 30 and the two inclined negative pressure pipes 31, and then discharged into the transparent observation tube 26 together. When the nitrite detection reagent a and the nitrite detection reagent b enter the drainage pipe 27, the vertical movement collides with the horizontal movement of the sampling liquid, and the first mixing will be carried out;

[0044] When the water level in the immersion cylinder 15 is lower than the lower end surface of the second rotating tube 32, the water is no longer discharged, and the sampling of the water is completed. At this time, the high-pressure gas will be discharged from the above-mentioned pipeline to the bottom of the transparent observation tube 26. When the sampled water reaches the critical point of being pressed out (the water level is just lower than the lower end surface of the second rotating tube 32), the high-pressure gas in the immersion cylinder 15 has been partially decompressed. Under the elastic action of the first spring 37, the first piston plate 35 will move back to contact the two conductive strips 36. At this time, the second normally open solenoid valve in the vertical pipe 30 is powered on and closed. At this time, the high-pressure gas will not inhale the nitrite detection reagent a and the nitrite detection reagent b through the discharge pipe 27. The high-pressure gas is blown into the transparent observation tube 26, which will promote the tumbling of the water and the mixing of the sampling liquid, the nitrite detection reagent a and the nitrite detection reagent b, so as to achieve secondary mixing and achieve an excellent mixing effect.

[0045] In addition, when the high-pressure gas is discharged quickly, the remaining water and reagents in the second rotating tube 32, the first rotating tube 7 and the drain tube 27 can be pressed out and air-dried at the same time to avoid the residual water in the tube body, which is difficult to clean later and breeds bacteria. Finally, the staff waits for 8-10 minutes to observe the color of the transparent observation tube 26 and compares it with the colorimetric card.

[0046] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
