[0013] The present invention also provides a method for detecting meat, the method comprising the following steps:

[0014] 1) The meat to be tested is placed on the surface of the placement plate and sensed by a pressure sensor. The display shows the mass of the placed sample. A servo motor drives the adjustment column to rotate. The adjustment column is connected to the adjustment plate by a thread and can drive the adjustment plate to move. The adjustment plate is fixedly connected to two first lifting plates. The two first lifting plates move with the adjustment plate. The outer side of the transmission gear is symmetrically meshed with racks. The two racks are fixedly connected to the first lifting plate and the second lifting plate respectively. Driven by the transmission gear, the first lifting plate moves in the opposite direction to the second lifting plate. The first lifting plate rises and the second lifting plate falls, which drives the box cover to fall. The fixed plate and the placement plate fall with the box cover. The placement plate contacts the surface of the fixed ring and stops. The first vertical column and the second vertical column slide relative to each other. The first spring is compressed. Then, the end of the cylinder away from the top block contacts the meat surface. As the first vertical column and the fixed plate continue to fall, the second spring is further compressed. The reaction force generated acts on the surface of the protrusion, so that multiple cylinders are in close contact with the meat placed on the surface of the placement plate, and are placed and positioned.

[0015] 2) Multiple heating plates are powered on and heated, while infrared heating lamps heat the surface of the meat. The infrared heating lamps can quickly reach the maximum heating power, and the meat being tested is quickly dried at high temperature. Air escapes from two circular holes, and the servo motor drives the adjusting column to rotate in the opposite direction to adjust to the initial position. The pressure sensor also senses this and displays it on the display screen, thus testing the moisture content of the meat being tested.

[0016] Compared with related technologies, the present invention provides the following beneficial effects:

[0017] This invention features a controller mounted on the surface of a U-shaped plate. A servo motor, heating plates, pressure sensors, infrared heating lamps, and a display screen are all connected to the controller via wires. The controller is precisely controlled by a computer or other control terminal. Utilizing the elastic force of a second spring, the reaction force generated by the compression of the second spring acts on the surface of the protrusions, ensuring close contact between multiple cylinders and the meat placed on the plate surface for stable positioning. Multiple heating plates are energized for heating, and infrared heating lamps heat the surface of the meat. The infrared heating lamps can quickly reach maximum heating power, rapidly drying the meat at high temperatures. Air escapes from two circular holes, and the servo motor drives the adjusting column to rotate in the opposite direction, adjusting it to the initial position. The pressure sensor detects this, and the result is displayed on the display screen, thus accurately measuring the moisture content of the tested meat. Attached Figure Description

[0034] A method for detecting meat, the method comprising the following steps:

[0035] 1) The meat to be tested is placed on the surface of the placement plate 33 and sensed by the pressure sensor 37. The display screen 8 shows the mass of the placed meat sample. The servo motor 15 drives the adjusting column 16 to rotate. The adjusting column 16 is threadedly connected to the adjusting plate 17, which can move the adjusting plate 17. The adjusting plate 17 is fixedly connected to two first lifting plates 18. The two first lifting plates 18 move with the adjusting plate 17. The outer side of the transmission gear 21 is symmetrically meshed with racks 20. The two racks 20 are fixedly connected to the first lifting plate 18 and the second lifting plate 19 respectively, and are driven by the transmission gear 21. The moving direction of the first lifting plate 18 is the same as that of the second lifting plate 19. The moving directions are opposite. The first lifting plate 18 rises and the second lifting plate 19 falls, causing the box cover 2 to fall. The fixing plate 29 and the placement plate 33 fall with the box cover 2. The placement plate 33 contacts the surface of the fixing ring 13 and stops moving. The first vertical column 25 and the second vertical column 26 slide relative to each other. The first spring 27 is compressed. Then, the end of the cylinder 30 away from the top block 31 contacts the meat surface. As the first vertical column 25 and the fixing plate 29 continue to fall, the second spring 28 is further compressed. The resulting reaction force acts on the surface of the protrusion 32, so that the multiple cylinders 30 are in close contact with the meat placed on the surface of the placement plate 33, and are placed and positioned.

[0036] 2) Multiple heating plates 7 are powered on and heated, and infrared heating lamps 11 heat the surface of the meat. Infrared heating lamps 11 can quickly reach the maximum heating power. The meat being tested is quickly dried at high temperature and air is released from two circular holes 12. The servo motor 15 drives the adjusting column 16 to rotate in the opposite direction and adjust it to the initial position. The pressure sensor 37 senses the moisture content and displays it on the display screen 8, thereby testing the moisture content of the meat being tested.

[0037] Working principle: A controller can be installed on the surface of the U-shaped plate 3. The servo motor 15, heating plate 7, pressure sensor 37, infrared heating lamp 11, and display screen 8 are all connected to the controller via wires. The controller is precisely controlled by a computer or other control terminal. The meat to be tested is placed on the surface of the placement plate 33, and the pressure sensor 37 senses it. The display screen 8 displays the mass of the placed sample. The servo motor 15 drives the adjusting column 16 to rotate, which in turn drives the adjusting plate 17 to move. The adjusting plate 17 is fixedly connected to two first lifting plates 18. The two first lifting plates 18 move with the adjusting plate 17. The transmission gear 21 meshes with two racks 20. The two racks 20 are fixedly connected to the first lifting plate 18 and the second lifting plate 19 respectively. Driven by the transmission gear 21, the first lifting plate 18 rises and the second lifting plate 19 falls, driving the box cover 2 to fall. The fixed plate 29 and the placement plate 33 fall with the box cover 2. When cylinder 30 contacts the surface of the fixing ring 13 and stops moving, the first vertical column 25 and the second vertical column 26 slide relative to each other, and the first spring 27 is compressed. Then, the end of cylinder 30 away from the top block 31 contacts the meat surface. As the first vertical column 25 and the fixing plate 29 continue to move downward, the second spring 28 is further compressed, and the resulting reaction force acts on the surface of the protrusion 32, so that multiple cylinders 30 are in close contact with the meat placed on the surface of the placement plate 33, and are positioned. Multiple heating plates 7 are energized and heated, and infrared heating lamps 11 heat the surface of the meat. Infrared heating lamps 11 can quickly reach the maximum heating power, and the meat being tested at high temperature is quickly dried. Air is released from the two circular holes 12, and the servo motor 15 drives the adjusting column 16 to rotate in the opposite direction to adjust to the initial position. Similarly, the pressure sensor 37 senses the signal and transmits it to the controller, which is displayed on the display screen 8, thereby testing the moisture content of the tested meat.
