[0002] Food safety issues directly affect people's health, and people are paying more and more attention to food safety. During the food production process, it is necessary to test the bacterial content of food to determine whether the produced food meets safety standards and whether it will cause harm to the health of consumers. The testing process requires the use of testing instruments.

[0003] According to patent CN112067763B, a microbial content detector for food production is disclosed, which includes a base plate, a vibration device, a rotation device, and an adjustment device.

[0004] The above-mentioned solution can stably hold the test tubes and perform testing on multiple sets of test tubes simultaneously. However, during the implementation of the above-mentioned solution, the testing personnel need to manually grind the food samples and add the ground samples one by one to the test tubes. This is not only time-consuming and labor-intensive, but also prone to contaminating the food samples during manual grinding, affecting the accuracy of the test. To address this issue, we provide a food production bacterial count detector to solve the above problems. Utility Model Content

[0027] This utility model provides a microbial content detector for food production.

[0028] Please see Figure 1 and Figure 2 The device includes a base 1, with a grinding box 2 mounted on top of the base 1. The base 1 provides stable support for the grinding and testing operations of the device. A servo motor that drives the grinding roller 3 to rotate is installed on the outside of the grinding box 2. The servo motor is existing technology and will not be described in detail in this application. Users can install a protective plate inside the grinding box 2 according to their needs to prevent food scraps from being ejected onto the outside of the filter screen 4 and affecting the normal operation of the internal structure.

[0029] The top surface of the grinding box 2 is fixedly connected to the feed inlet 10, and the bottom surface of the grinding box 2 is fixedly connected to the support column 11. The support column 11 is fixedly connected to the base 1. The feed inlet 10 facilitates the testing personnel to put the food samples to be tested into the grinding box 2 for grinding, reducing the workload of manually grinding samples and avoiding the impact of manual grinding and feeding on the final testing accuracy of the samples.

[0030] An ATP fluorescence detector 9 is fixedly installed on the top surface of the base 1. Inside the ATP fluorescence detector 9 is a set of test tubes containing sterile physiological saline, which can better preserve the sample and will not affect the device's detection results of the bacterial content of food. The ATP fluorescence detector 9 is prior art and will not be described in detail in this application. The food residue ground by the grinding box 2 is transported to the test tubes in the ATP fluorescence detector 9 through the flexible hose 8, which facilitates the detection of the bacterial content of food by the ATP fluorescence detector 9, reduces the workload of manual grinding and feeding, and improves the detection rate.

[0031] Please see Figure 2 and Figure 3 Inside the grinding box 2, two grinding rollers 3 are rotatably installed. Gears 31 are fixedly connected to the outer surfaces of the two grinding rollers 3. The two gears 31 mesh with each other. The output shaft of the servo motor installed outside the grinding box 2 is fixedly connected to one of the grinding rollers 3. When the servo motor starts, it can drive the connected grinding roller 3 to rotate. Under the action of the meshing of the two gears 31, the other grinding roller 3 will also start to rotate. The two grinding rollers 3 rotate in opposite directions, thereby grinding the food that falls into them.

[0032] Please see Figure 2 A filter screen 4 is fixedly connected inside the base 1. The filter screen 4 has small mesh holes, which can catch the food residue after grinding by the grinding roller 3 and make it fall more evenly into the collection box 7. The mesh holes of the filter screen 4 are opposite to the middle of the collection box 7, which can effectively prevent the residue from falling on the side of the collection box 7 and causing sample waste.

[0033] Two arc-shaped slides 6 are fixedly connected to the inner wall of the grinding box 2. The two ends of the cleaning rod 503 are slidably connected to the two arc-shaped slides 6 respectively. The curvature of the arc-shaped slides 6 is adapted to the filter screen 4. The arc-shaped slides 6 can support and limit the sliding of the cleaning rod 503, so that the cleaning rod 503 moves back and forth on the surface of the filter screen 4, thereby sweeping the debris on the filter screen 4 through the mesh into the collection box 7. The outer surface of the cleaning rod 503 is provided with two sets of positioning rings. Each set of positioning rings can make slight contact with the arc-shaped slides 6. The positioning rings can prevent the cleaning rod 503 from deviating when sliding.

[0034] A set of collection boxes 7 are fixedly connected inside the grinding chamber 2. Each collection box 7 has a flexible hose 8 fixedly connected to its bottom end. The collection box 7 can collect and gather the ground food residue, so that the residue is transported to the ATP fluorescence detector 9 for detection under the action of gravity through the flexible hose 8. This reduces the impact of external contact on the bacterial content of food and improves the detection accuracy of the device. The flexible hose 8 has good flexibility and can be bent at will according to the transportation requirements. The number of collection boxes 7 and flexible hoses 8 is determined by the detection requirements. If more samples need to be tested at the same time, the volume of the collection boxes 7 can be reduced and the number of them increased during the production of this device.

[0035] Please see Figure 2 and Figure 4 The base 1 is equipped with a transmission mechanism 5 for cleaning the filter screen 4. The transmission mechanism 5 includes a transmission groove 501. The transmission groove 501 has a partition plate in the middle and cross grooves on both sides, which can make the driven slider 502 and the transmission slider 507 slide stably inside the transmission groove 501, thereby improving the stability of the device.

[0036] A limiting slide bar 508 is fixedly connected to the outer surface of the transmission groove 501, and a supporting slide bar 509 is fixedly connected to the inner wall of the grinding box 2. The limiting slide bar 508 and the supporting slide bar 509 are slidably connected. By setting the limiting slide bar 508 and the supporting slide bar 509, it can be ensured that the transmission groove 501 can slide back and forth in the horizontal direction inside the grinding box 2, so as to avoid the transmission groove 501 from tilting under the transmission action of the transmission slider 507 and ensure the normal operation of the transmission mechanism 5.

[0037] A driven slider 502 is slidably connected inside the transmission groove 501. A cleaning rod 503 is fixedly connected to the outer surface of the driven slider 502. When the transmission groove 501 moves horizontally back and forth, it can drive the cleaning rod 503 to slide back and forth inside the arc-shaped slide 6, thereby cleaning the surface of the filter screen 4 with the cleaning rod 503 and sweeping the debris through the mesh into the collection box 7, so as to avoid the debris from accumulating on the filter screen 4 and causing the filter screen 4 to become clogged.

[0038] Please see Figure 3 and Figure 4 The base 1 is internally connected to a transmission rod 504. Both the transmission rod 504 and the outer surface of the grinding roller 3 are equipped with pulleys. The two pulleys are connected by belt drive. When the grinding roller 3 rotates to start grinding, it can drive the transmission rod 504 to rotate through the belt drive, thereby providing power for the operation of the transmission mechanism 5 and improving the energy utilization efficiency of the device.

[0039] One end of the transmission rod 504 is fixedly connected to a transmission plate 505. A connecting post 506 is fixedly connected to the outer surface of the transmission plate 505. A transmission slider 507 is rotatably connected to the outer surface of the connecting post 506. The transmission slider 507 is slidably connected to the transmission groove 501. The rotation of the transmission rod 504 can drive the transmission plate 505 to rotate. The rotation of the transmission plate 505 can drive the connecting post 506 to rotate. The rotation of the connecting post 506 can drive the transmission slider 507 to rotate. However, due to the limiting slide bar 508 and the supporting slide bar 509 limiting the transmission groove 501, the transmission groove 501 will slide back and forth inside the grinding box 2 as the transmission slider 507 rotates.

[0040] Working principle: The testing personnel first start the servo motor, and then put the food to be tested into the feed inlet 10. When the food passes through the grinding rollers 3, it will be ground into small pieces by the two grinding rollers 3 and fall onto the filter screen 4. While grinding, the grinding rollers 3 can also drive the transmission rod 504 to rotate via the belt. The rotation of the transmission rod 504 drives the transmission groove 501 to move horizontally back and forth inside the grinding box 2. The movement of the transmission groove 501 drives the cleaning rod 503 to move. Under the limit of the arc-shaped slide 6, the cleaning rod 503 will slide inside the arc-shaped slide 6 and clean the surface of the filter screen 4, sweeping the small pieces into the collection box 7. The small pieces inside the collection box 7 will be injected into the test tube in the ATP fluorescence detector 9 through the flexible hose 8. After the small pieces are injected, the top cover of the protective test tube is closed and the ATP fluorescence detector 9 is started to begin testing the bacterial content of the food.
