Description

Technical Field

[0002] Salt can inhibit the growth of bacteria and microorganisms, thereby extending the shelf life of food. In traditional food processing, salt is an important preservative and can also enhance the flavor of food, highlight the taste of other spices, and improve the texture of food.

[0003] Since excessive salt can pose health risks, it is necessary to test the salinity of food. A patent with authorization publication number CN218726566U discloses an online salinity detection device with a cleaning function. While performing online salinity detection of food juices, it also ensures the cleanliness of the salinity meter's monitoring probe through its cleaning function, preventing contamination of the probe by food juices and ensuring the accuracy of subsequent test results.

[0004] Traditional methods for salinity detection include titration, specific gravity, conductivity meter testing, and electronic tongue technology. Among these, the conductivity sensor required for conductivity testing consists of two electrodes and is used to measure the conductivity of a solution. During use, the sensor is immersed in the food solution to obtain the measurement result. However, after use, the electrodes immersed in the food solution are still exposed to the external environment, and the residual salt on the electrodes can easily cause pollution to the outside world, affecting the normal use of the device. Utility Model Content

[0005] In view of the problem that the electrodes of the existing devices, which are immersed in the food solution to be tested, are still exposed to the external environment after use, and the residual salt on the electrodes can easily cause pollution to the outside world and affect the normal use of the device, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a salt content detection device for high-salt foods, the purpose of which is to completely retract the lowest end of the inner sleeve column into the cleaning chamber after use, thereby avoiding contamination of the external environment by the detection probe and conductive electrode containing salt.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a salt content detection device for high-salt food, which includes a detection box and a preparation tank, wherein a protective component is provided on the top of the preparation tank and an expansion component is provided on the outside of the detection box; The protective component includes an adjusting member, which includes an outer sleeve. A cleaning chamber is provided at one end of the outer sleeve near the preparation tank. An inner sleeve column is provided inside the cleaning chamber, and the inner sleeve column penetrates the entire outer sleeve. A piston ring is fixedly installed on the outer side of the inner sleeve column. The piston ring is movably connected to the top of the cleaning chamber through the inner sleeve column.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example 1

[0025] Reference Figures 1-6 This is the first embodiment of the present invention, providing a salt content detection device for high-salt foods. This device includes a detection chamber 1 and a preparation tank 2. A protective component 3 is provided on the top of the preparation tank 2, and an expansion component 4 is provided on the outside of the detection chamber 1. The protective component 3 includes an adjusting member 31, which includes an outer sleeve 311. A cleaning chamber 312 is formed at one end of the outer sleeve 311 near the preparation tank 2. An inner sleeve 313 is provided inside the cleaning chamber 312, penetrating the entire outer sleeve 311. A piston ring 314 is fixedly installed on the outside of the inner sleeve 313, and the piston ring 314 is movably connected to the top of the cleaning chamber 312 via the inner sleeve 313. An elastic member 315 is provided between the piston ring 314 and the cleaning chamber 312, located outside the inner sleeve 313. The testing chamber 1 is a sealed box structure, and the relevant materials of the device meet food inspection standards. It is equipped with weighing instruments required for preparing the test solution. The preparation tank 2 is a transparent measuring cup with graduations on its surface, and can prepare test solutions for high-salt foods required for testing. The outer sleeve 311 is suspended in the test solution during use. The inner diameter of the cleaning chamber 312 is the same as the diameter of the inner sleeve column 313. When the inner sleeve column 313 protrudes, the cleaning chamber 312 is isolated from the external environment. When the elastic element 315 extends, it can push the piston ring 314, causing the inner sleeve column 313 to move away from the end of the cleaning chamber 312, thereby drawing the spray pipe 321 into the cleaning chamber 312. When the elastic element 315 is fully extended, the lowest end of the inner sleeve column 313 is completely inside the cleaning chamber 312, at which point the cleaning chamber 312 is connected to the external environment.

[0026] The adjusting component 31 also includes a rubber roller 316, which is located at the end of the outer sleeve 311 away from the cleaning chamber 312. The rubber roller 316 is fixedly connected to the outside of the inner sleeve column 313 by a handle 317. The rubber roller 316 is made of rubber material and is semi-circular. When the handle 317 is rotated, it squeezes the inner sleeve column 313 and deforms itself, thus restricting the movement of the inner sleeve column 313.

[0027] The protective component 3 also includes a detection element 32, which includes a spray pipe 321. The spray pipe 321 penetrates the entire inner sleeve column 313 and is on the same straight line as the axis center of the inner sleeve column 313. The end of the spray pipe 321 away from the cleaning chamber 312 is connected to a water supply pipe 322. The end of the spray pipe 321 near the cleaning chamber 312 is provided with a nozzle and can move synchronously with the inner sleeve column 313 in the outer sleeve 311.

[0028] A detection probe 323 and a conductive electrode 324 are respectively provided on the outside of the spray pipe 321. The conductive electrodes 324 are arranged in parallel with each other. The ends of the detection probe 323 and the conductive electrode 324 away from the cleaning chamber 312 are connected to wires 325. The detection probe 323 can detect the electrolysis rate in the solution. The conductive electrode 324 is a stainless steel or platinum electrode, and the electrodes are opposite.

[0029] The expansion component 4 includes an extension bracket 41, one end of which is fitted with a sleeve clamp 42. The sleeve clamp 42 is connected to the detection box 1 through the extension bracket 41. The outer sleeve 311 is set on the top of the preparation tank 2 through the sleeve clamp 42. The hinge joints of the extension bracket 41 are equipped with bolts for adjusting the angle. The sleeve clamp 42 is made of rubber and can suspend the outer sleeve 311 in the solution in the preparation tank 2 by its own contraction.

[0030] A clean water tank 43 is installed at the bottom of the detection box 1. The clean water tank 43 is connected to the spray pipe 321 through the water supply pipe 322. A salinity meter 44 is also installed on the outside of the detection box 1. The salinity meter 44 is connected to the detection probe 323 and the conductive electrode 324 through the wires 325 respectively. The clean water tank 43 can supply water to the spray pipe 321 through the water supply pipe 322 to clean the cleaning chamber 312. The clean water tank 43 can obtain the salt content in the solution by using the conductivity detected by the detection probe 323 through the water supply pipe 322 and the conductive electrode 324 through the water supply pipe 322. The clean water tank 43 can supply alternating current to the conductive electrode 324 through the water supply pipe 322.

[0031] A cutting table 45 is fixedly installed on the top of the water tank 43 and inside the test box 1. A back plate 46 is hinged to the top of the cutting table 45. A cutting component 47 is provided on the outer side of the back plate 46. The cutting component 47 is installed on the side of the back plate 46 near the cutting table 45 via a guide rail 48. The surface of the cutting table 45 is provided with a guide plate and drainage holes for easy cleaning. The cutting component 47 can move on the back plate 46 via the guide rail 48 to complete the cutting of high-salt food on the cutting table 45, thereby facilitating the preparation of the test solution.

[0032] In use, the high-salt food sample to be tested is cut and weighed by the cutting piece 47 on the cutting table 45 and weighing instrument in the testing chamber 1. Then, the test solution is prepared in the preparation tank 2. After the solution is prepared, the outer sleeve 311, which meets the food testing standards, is suspended in the solution in the preparation tank 2. The rubber roller 316 is rotated to release the pressure on the inner sleeve column 313. The inner sleeve column 313 is pressed down, causing the piston ring 314 to compress the elastic element 315. The extension length of the elastic element 315 decreases, and the inner sleeve column 313 protrudes from the spray pipe 321 and reaches the designated position. The movement of the inner sleeve column 313 is restricted by the compression of the rubber roller 316. During the detection process, the cleaning chamber 312 is isolated from the external environment. The detection probe 323 and the conductive electrode 324 are completely immersed in the solution. Salt ions in the detection solution will dissociate into charged ions, thereby increasing the conductivity of the solution. The salinity meter 44 applies a known AC voltage to the parallel conductive electrode 324 through the wire 325. The detection probe 323 measures the current passing through the solution and calculates the resistance value of the solution according to Ohm's law. The data is transmitted to the salinity meter 44 through the wire 325. Due to the conductivity... It is the reciprocal of the resistance, so the conductivity of the solution can be calculated. The processing end of the salinity meter 44, through the functional relationship between the conductivity of the solution and the concentration of salt (sodium chloride), converts the conductivity value measured by the detection probe 323 into the corresponding salt concentration value through calibration curves or algorithms, thereby completing the salt content detection of high-salt foods. After the detection is completed, by releasing the pressure of the rubber roller 316 on the inner sleeve column 313, the elastic element 315 is allowed to extend, pushing the inner sleeve column 313 connected to the piston ring 314 into the cleaning chamber 312. When the elastic element 315 is fully extended, the inner sleeve column 313 is pushed into the cleaning chamber 312. The lowest end of the sleeve column 313 is completely inserted into the cleaning chamber 312. At this time, the cleaning chamber 312 is connected to the external environment, thereby preventing the detection probe 323 and conductive electrode 324, which contain salt, from contaminating the outside world and ensuring the stable operation of the device. At the same time, the clean water tank 43 supplies water to the spray pipe 321 through the water supply pipe 322 to clean the detection probe 323 and conductive electrode 324 in the cleaning chamber 312. The wastewater after cleaning falls into the preparation tank 2 through the connected cleaning chamber 312 and is collected, ensuring the cleanliness of the detection probe 323 and conductive electrode 324 and ensuring the accuracy of subsequent test results.
