Description

Technical Field

[0001] This utility model relates to the field of gas phase infrared spectroscopy detection technology, specifically a gas phase infrared spectroscopy non-destructive testing device for the production of stinky mandarin fish. Background Technology

[0002] The production of stinky mandarin fish involves four core steps: material selection, pickling, fermentation, and post-processing. To ensure food safety, the fermentation status of the stinky mandarin fish needs to be tested during production.

[0003] Existing technologies for testing stinky mandarin fish cannot determine the factors that cause fermentation damage; they can only determine that the fermentation is incomplete, which has certain limitations.

[0004] Therefore, we propose a gas phase infrared spectroscopy non-destructive testing device for the production of stinky mandarin fish to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a gas phase infrared spectroscopy non-destructive testing device for the production of stinky mandarin fish, so as to solve the problem that when testing stinky mandarin fish, the influencing factors of fermentation damage cannot be determined, and it can only be determined that the fermentation is incomplete, which has certain limitations.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a gas phase infrared spectroscopy non-destructive testing device for the production of stinky mandarin fish, comprising a working box, an infrared spectrometer for detecting the gas of stinky mandarin fish is fixedly connected inside the working box, and a headspace bottle for storing stinky mandarin fish is placed inside the working box. A motor is fixedly connected to the lower surface inside the working box, and a turntable is fixedly connected to the output end of the motor. A clamping mechanism is provided between the side of the turntable and the working box. The clamping mechanism achieves clamping and limiting of the headspace bottle by moving the movable plate contained therein.

[0007] Furthermore, the clamping mechanism includes a rotating rod, which is hinged to the side of the turntable, and the other end of the rotating rod is hinged to a pull rod. A limit groove is provided on the work box, and the pull rod is slidably connected inside the limit groove. The upper end of the pull rod is fixedly connected to the lower surface of the moving plate.

[0008] Furthermore, two sets of rotating rods are symmetrically distributed about the center of the turntable, and the rotating rods form a rotating structure through the turntable and the pull rod.

[0009] Furthermore, a first spring is fixedly connected to the inner side of the movable plate, and a clamping plate is fixedly connected to the other end of the first spring. Both the clamping plate and the movable plate are arranged in an arc shape.

[0010] Furthermore, a connecting hose is provided through the upper side of the headspace bottle, and the other end of the connecting hose is provided below the infrared spectrometer, and a valve is provided inside the connecting hose.

[0011] Furthermore, a movable box is fixedly connected to the cap of the headspace bottle, and a movable plate electrically connected to the valve inside the connecting hose is fixedly connected to the top side of the movable box, and a pull rod is slidably connected to the cap of the headspace bottle.

[0012] Furthermore, the lower end of the pull rod is fixedly connected to a floating ball that extends into the movable box, and the upper end of the pull rod is fixedly connected to a pressing plate for pressing the button, and a second spring is fixedly connected between the lower surface of the pressing plate and the top-hole bottle cap body.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Place the fermented mandarin fish sample during the production process inside a headspace vial, leaving sufficient space at the top. Allow it to stand in a constant temperature environment to promote the release of volatile components from the fermented mandarin fish into the headspace of the vial. The released gas is then introduced into the long-path gas cell of an infrared spectrometer through a connecting tube. By continuously scanning the headspace gas with an infrared spectrometer, the dynamic changes are recorded, thereby monitoring the state of the fermented mandarin fish during production and determining whether it has been damaged. The infrared spectrometer can be used to analyze the components of the fermented volatile gases to determine the cause of the damage.

[0015] 2. The headspace bottle is placed inside the working chamber. The headspace bottle can be fixed by moving the sliding plates on both sides, thereby preventing the headspace bottle from tipping over and ensuring the accuracy of the test.

[0016] 3. Start the motor. The motor drives the turntable to rotate. The rotating turntable will synchronously drive the rotating rod on the side to rotate. At this time, the rotating rod will pull the pull rod to move along the inside of the limiting groove, thereby causing the pull rod to drive the moving plate to change position and achieve the fixed clamping of the headspace bottle.

[0017] 4. When the moving plate clamps the headspace bottle, the clamping plate will contact the side of the headspace bottle. During the continuous movement, the clamping plate will squeeze the first spring, causing the first spring to deform. Driven by the elastic force of the first spring, the clamping plate can flexibly fix the headspace bottle, thereby avoiding the phenomenon of damage to the headspace bottle due to excessive clamping force.

[0018] 5. When the stinky mandarin fish releases gas inside the headspace vial, as the gas content increases, the float will rise due to the gas's influence. This will cause the lever to move upwards along the headspace vial cap, thereby pressing the button on the pressure plate. The button activates the valve inside the connecting hose, allowing the gas to enter the infrared spectrometer for detection. The float allows the gas to be stored to a certain level before being released for detection, ensuring the accuracy of the detection. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1: As Figure 1 and Figure 2The technical solution shown is provided by the present utility model as follows: a gas phase infrared spectroscopy non-destructive testing device for the production of stinky mandarin fish, which discloses an infrared spectrometer 3.

[0028] The stinky mandarin fish sample during the production process is placed inside headspace vial 2, with space reserved at the top. It is then left to stand in a constant temperature environment to promote the release of volatile components from the stinky mandarin fish into the headspace of headspace vial 2. The released gas is then introduced into the long-path gas cell of infrared spectrometer 3 through connecting tubing 4. By continuously scanning the headspace gas with infrared spectrometer 3, dynamic changes are recorded, thereby monitoring the state of the stinky mandarin fish during production and fermentation and determining whether it has been damaged.

[0029] Example 2: Figure 2 , Figure 3 and Figure 4 The technical solution shown is provided by this utility model as follows: A gas phase infrared spectroscopy non-destructive testing device for the production of stinky mandarin fish, which discloses a clamping mechanism to prevent the headspace bottle 2 from tipping over: a motor 9 is fixedly connected to the lower inner surface of the working box 1, and a turntable 11 is fixedly connected to the output end of the motor 9. A clamping mechanism is provided between the side of the turntable 11 and the working box 1. The clamping mechanism achieves clamping and limiting of the headspace bottle 2 by moving the movable plate 6 included therein. The clamping mechanism includes a rotating rod 12, which is hinged to the turntable 11. The side of the rotating rod 12 is hinged to the other end of the pull rod 13. The working box 1 has a limit groove 10. The pull rod 13 is slidably connected inside the limit groove 10. The upper end of the pull rod 13 is fixedly connected to the lower surface of the moving plate 6. Two sets of rotating rods 12 are symmetrically distributed about the center of the turntable 11. The rotating rods 12 and the pull rod 13 form a rotating structure through the turntable 11. The inner side of the moving plate 6 is fixedly connected to the first spring 8. The other end of the first spring 8 is fixedly connected to the clamping plate 7. Both the clamping plate 7 and the moving plate 6 are arranged in an arc shape.

[0030] The headspace vial 2 is placed inside the working chamber 1. The headspace vial 2 can be limited and fixed by the movement of the movable plates 6 on both sides, thereby preventing the headspace vial 2 from tipping over and ensuring the accuracy of the test. The motor 9 is started, and the motor 9 drives the turntable 11 to rotate. The rotated turntable 11 will synchronously drive the rotating rod 12 on the side to rotate. At this time, the rotating rod 12 will pull the pull rod 13 to move along the inside of the limiting groove 10, thereby causing the pull rod 13 to drive the movable plate 6 to change position, thereby achieving the fixed clamping of the headspace vial 2. When the movable plate 6 moves to clamp the headspace vial 2, the clamping plate 7 will contact the side of the headspace vial 2. During the continuous movement, the clamping plate 7 will squeeze the first spring 8, causing the first spring 8 to deform. Under the drive of the elastic force of the first spring 8, the clamping plate 7 can flexibly fix the headspace vial 2, thereby avoiding the phenomenon of damage to the headspace vial 2 due to excessive clamping force.

A connecting hose 4 is provided through the upper side of the headspace bottle 2, and the other end of the connecting hose 4 is provided through the infrared spectrometer 3. A valve is provided inside the connecting hose 4. A movable box 5 is fixedly connected to the cap of the headspace bottle 2. A movable plate 6, which is electrically connected to the valve inside the connecting hose 4, is fixedly connected to the top side of the interior of the movable box 5.

[0032] Stinky mandarin fish releases gas inside headspace vial 2. As the gas content increases, float ball 16 will float due to the gas. At this time, it can drive lever 13 to move upward along the cap of headspace vial 2, thereby causing press plate 15 to press button 14. Button 14 activates the valve inside connecting hose 4, allowing gas to enter infrared spectrometer 3 for detection.
