[0025] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0026] Example 1:

[0027] See Figure 1-4A novel rapid detection device for mutton freshness includes a housing 1. The top of the housing 1 has a first placement port 11 and a detection port 12. The first placement port 11 is used to place the mutton to be tested into the housing 1 for detection. Above the detection port 12 is a vertically movable colorimeter 2. The detection port 12 is used to insert the detection end of the colorimeter 2 into the housing 1 for detection. An adjustment component 3 is provided on one side of the housing 1 for suspending and supporting the vertically guiding movement of the colorimeter 2. A horizontal partition 4 divides the chamber 1 into upper and lower compartments. The upper compartment is used to test the freshness of the mutton. All side panels of the chamber 1 are insulated. The lower compartment is used to store the cold air required for chilling. A bearing seat 41 is fixed on the partition 4, and a bearing is installed inside. A vertical rotating shaft 42 is rotatably mounted on the bearing. The lower end of the rotating shaft 42 is rotatably connected to the bearing. A rotating plate 43 is installed at the upper end of the rotating shaft 42 for placing the mutton to be tested. The mutton to be tested is evenly placed on the rotating plate 43. The rotating disk 43 rotates to move the mutton to be tested to below the detection port 12 for detection by the colorimeter 2. A first gear 44 is coaxially fixed on the rotating shaft 42, and a second gear 45 is set on one side of the first gear 44 to mesh with it. A first motor 46 is fixed at the bottom of the partition 4. The output shaft of the first motor 46 passes through the partition 4 and extends to the top of the partition 4, where it is coaxially fixedly connected with the second gear 45. The first motor 46 drives its output shaft to rotate, causing the second gear 45 to mesh with the first gear 44. The first gear 44 drives the rotating shaft 42 and the rotating disk 43 to rotate, moving the mutton to be tested on the rotating disk 43 to below the detection port 12 in sequence. The colorimeter 2 is then adjusted by the adjustment component 3 to extend its detection end from the detection port 12 into the housing 1 to perform colorimetric detection on the mutton. Multiple positions of the mutton can be detected simultaneously. By comparing the detected color with the color of fresh mutton, the freshness of the mutton can be determined. The detection speed is fast and the measurement accuracy is high.

[0028] In this embodiment, see Figure 1-4The adjustment assembly 3 includes a support plate 31, a lifting block 32, a compression spring 33, and a positioning ring 34. The support plate 31 is vertically positioned on the top of the housing 1. A vertically penetrating guide hole 311 is provided on the top of the support plate 31. The guide hole 311 is rectangular in shape. Two guide grooves 312 are symmetrically arranged on the two side walls of the guide hole 311. The two guide grooves 312 are horizontally connected to the guide hole 311 of the support plate 31. The compression spring 33 is vertically positioned inside the guide hole 311. The lower end of the compression spring 33 is elastically fixed to the support plate 31. A horizontal lifting block 32 is provided on the upper end of the compression spring 33. The shape of the lifting block 32 is the same as that of the guide hole 311 and is clearance-fitted with the guide hole 311. The lifting block 32 can move vertically along the guide hole 311. The lifting block 32 is guided by two horizontal guide plates 321 on both ends. The two guide plates 321 are placed in two guide grooves 312 for vertical guidance and cooperation. The guide plate 321 on one side of the lifting block 32 is fixedly connected to the horizontally set positioning ring 34. The positioning ring 34 is sleeved on the colorimeter 2 for positioning and fixed connection. By pressing the lifting block 32, the compression spring 33 is compressed and the colorimeter 2 on the positioning ring 34 is lowered. The detection end of the colorimeter 2 extends into the box 1 from the detection port 12 to contact the mutton to be tested and identify the color of the mutton. After the test is completed, the lifting block 32 is released. Under the action of the rebound force of the compression spring 33, the colorimeter 2 automatically rises and moves out of the box 1.

[0029] In this embodiment, see Figure 3 The side wall of the positioning ring 34 is provided with three radially distributed positioning threaded holes along the circumferential direction. Each positioning threaded hole is provided with an adjusting screw 341. The outer shell of the colorimeter 2 is pressed against the middle position of the positioning ring 34 by the positioning movement of the three adjusting screws 341 along the circumferential direction, so that the colorimeter 2 is stably fixed on the positioning ring 34, which facilitates the disassembly and installation of the colorimeter 2.

[0030] In this embodiment, see Figure 4 The partition 4 is provided with an air inlet 47 and an air outlet 48, which are located at both ends of the partition 4. The air inlet 47 is used to supply chilled air, and the air outlet 48 is used to circulate the air into the lower compartment for cooling. A vertical air inlet pipe 473 is installed inside the air inlet 47. The outer wall of the air inlet pipe 473 is sealed to the air inlet 47. A fan 472 is installed at the upper end of the air inlet pipe 472. The fan 472 is a commercially available device. It is used to circulate the chilled air from the lower compartment into the upper compartment to chill the mutton to be tested in the upper compartment and ensure that the temperature of the mutton is consistent. An air filter 474 is installed at the lower end of the air inlet pipe 473. The air filter 474 is a commercially available product. The air filter 474 filters the air passing through the air inlet pipe 473.

[0031] In this embodiment, see Figure 4A first air valve 471 is installed on the air inlet pipe 473, and an exhaust pipe 475 is installed inside the exhaust port 48. A second air valve 476 is installed on the exhaust pipe 475. The first air valve 471 controls the opening and closing of the air inlet pipe 473, and the second air valve 476 controls the opening and closing of the gas in the exhaust pipe 475.

[0032] In this embodiment, see Figure 4 A second placement opening 14 is provided on the side wall of the box body 1. A box door 15 is provided on the second placement opening 14 for sealing the second placement opening 14. Multiple ice packs 16 are provided at the bottom of the box body 1 to reduce the temperature inside the box body 1, so as to facilitate the refrigeration of mutton and to test the mutton after it reaches the detection temperature. A temperature sensor 5 is provided on the side wall of the box body 1, and a sealing cover 13 is provided on the first placement opening 11.

[0033] In this embodiment, the colorimeter 2 is a commercially available product, model number DS-700D. The spectrophotometer 2 automatically calibrates the instrument using a white board.

[0034] In this embodiment, both the first air valve 471 and the second air valve 476 are solenoid valves, which can be controlled to start and stop by buttons on the controller, or they can be controlled by PLC programming.

[0035] In this embodiment, disposable sterile paper is placed on the rotating disk 43. The mutton to be tested is placed on the sterile paper, and after the test is completed, the sterile paper is replaced to keep the rotating disk clean.

[0036] In this embodiment, a germicidal lamp can be installed on the top of the chamber 1 to sterilize the inside of the chamber 1 and ensure the safety of the testing environment.

[0037] As can be seen from the above technical solution, in use, firstly, a glass cover is placed on the detection port 12, and then an intelligent calibration base is placed on the glass cover. By pressing the lifting block 32, the compression spring 33 is compressed, which causes the colorimeter 2 on the positioning ring 34 to descend, so that the detection end of the colorimeter 2 extends into the intelligent calibration base. The instrument is automatically calibrated by the white board on the intelligent calibration base. After calibration, the sealing cover 13 on the first placement port 11 is opened, and samples of four different parts of the mutton to be tested are taken and evenly placed on the rotating plate 43. Then, the door 15 of the second placement port 14 is opened, and multiple ice packs 16 are placed into the lower compartment. Then, the door 15 and the sealing cover 13 are closed, and the detection port 12 is sealed by the glass cover. The first air valve 471 and the second air valve 476 are opened, and the fan 472 is turned on by the controller to draw air from the lower compartment of the box 1 into the upper compartment to cool the upper compartment to 4 degrees Celsius. Then, the first air valve 471 and the second air valve 476 are closed. The glass cover is then removed from the detection port 12. The controller controls the first motor 46 to drive its output shaft to rotate, which drives the second gear 45 to mesh with the first gear 44. The first gear 44 drives the rotating shaft 42 and the rotating disk 43 to rotate, rotating the mutton to be tested on the rotating disk 43 to the bottom of the detection port 12. At the same time, the operator presses the lifting block 32. By pressing the lifting block 32, the compression spring 33 is compressed and the colorimeter 2 on the positioning ring 34 is lowered, so that the detection end of the colorimeter 2 extends into the box 1 to contact the mutton to be tested and identify the color of the mutton. After each test is completed, the lifting block 32 is released. Under the action of the rebound force of the compression spring 33, the colorimeter 2 automatically rises and moves out of the box 1, completing the test and recording the color value of each sample. The color value is then compared with that of standard fresh mutton to evaluate the freshness of the mutton.
