Description

Technical Field

[0001] The present invention relates to the technical field of near-infrared detection of meat moisture, and particularly to a device for detecting internal moisture of meat quality. Background Art

[0002] In the detection of meat moisture, the near-infrared spectroscopy method measures the moisture content by scanning the meat product, capturing the characteristic absorption peak of the O-H bond in the water molecule, and combining with a pre-established calibration model.

[0003] Chinese Patent CN103558177B discloses a near-infrared detection device for raw meat tissue moisture, including: an optical signal transmitter for emitting n-channel pulsed optical signals of n predetermined wavelengths with a predetermined duty cycle and a predetermined frequency to the surface of the raw meat to be measured, where n≥3; a detection circuit for receiving the n-channel pulsed optical signals diffusely reflected by the raw meat to be measured and converting the diffusely reflected n-channel pulsed optical signals into n×m spectral signals, where m represents receiving the diffusely reflected n-channel pulsed optical signals at m different positions, and m≥2; a calculation and processing device connected to the detection circuit for calculating n×m diffuse reflectivities from the n×m spectral signals, establishing a linear relationship model between the n×m diffuse reflectivities and the moisture content of the raw meat tissue, and calculating the moisture content of the raw meat tissue to be measured according to the relationship model.

[0004] Chinese Patent CN219830829U discloses a non-contact near-infrared spectroscopy detection structure, including a near-infrared main unit and a tank for containing the liquid to be detected. The window of the near-infrared main unit is located outside the side wall of the tank, and the side wall is made of transparent glass; a reflector corresponding to the window is arranged inside the tank, and the reflector is located below the liquid level of the liquid to be detected for reflecting the light back to the near-infrared main unit; the distance between the surface of the reflector facing the window and the inner wall of the tank is greater than zero, so that a large-spot near-infrared main unit can be used for non-contact full-process on-line detection under the condition of large changes in the concentration of the substance to be detected, and the detection result is accurate while avoiding contamination of the liquid to be detected.

[0005] The following problems exist in the above patents and the prior art: In reality, meat itself is uneven, especially the surface of the meat is uneven and cannot be unified. When near-infrared light irradiates the uneven surface, the scattering direction and intensity of the light will become inconsistent. This physical effect will be superimposed on the chemical absorption information and will become the main source of noise. Especially when the laboratory needs to precisely control the moisture content of meat, the above problems will lead to differences in the test results. If the meat is minced, it is necessary to manually transfer and take out the minced meat, scrape it flat in a container and then conduct the test. During the transfer and scraping process of the minced meat, it needs to flow through different containers and be in contact with air for a long time, resulting in the transfer and loss of moisture inside the minced meat.

[0014] As a preferred solution of the internal moisture detection device for meat quality of the present invention, wherein: a bottom circular plate is threadedly connected to the bottom of the rotary cylinder, the bottom circular plate and the rotary cylinder form a docking port, and the docking port is rotationally sleeved on the surface of the protruding column; A central rod is fixedly connected to the top of the bottom circular plate, the hollow clamping rod is composed of a solid column at the top and a hollow column at the bottom, and the hollow clamping rod is movably sleeved on the surface of the central rod through the hollow column at its bottom.

[0015] As a preferred solution of the internal moisture detection device for meat quality of the present invention, wherein: a plurality of through holes are opened on the surface of the rotary cylinder, blades are movably arranged inside the through holes, outer blades are fixedly connected to the side of the blades opposite to the rotary cylinder, and inner blades are fixedly connected to the side of the blades opposite to the rotary cylinder; The inner contour of the opening of the through hole is coated with an elastic layer, the surfaces of the outer blades and the inner blades are coated with an elastic layer, and the rotary cylinder is movably connected to the blades through clamping strips.

[0016] As a preferred embodiment of the internal moisture detection device for meat quality according to the present invention, wherein: a plurality of trigger blocks are annularly arranged on the surface of the support rod, and clamping plates are symmetrically arranged on the side of the trigger block; A restraint rod is fixedly connected to the inner wall of the rotating cylinder. A roller is movably arranged on the surface of the trigger block. A through rod is horizontally movably connected to the surface of the restraint rod. The through rod is fixedly connected to the side of the roller. An elastic member is sleeved on the surface of the through rod. One side of the elastic member is fixedly connected to the surface of the roller, and the other side of the elastic member is fixedly connected to the surface of the restraint rod. The side of the through rod opposite to the trigger block movably passes through the restraint rod and is fixedly connected to the inner piece. The distance between the restraint rod and the rotating cylinder is greater than the length of the blade.

[0017] Advantages of the present invention: First, after the socket is inserted into the minced meat, the rotating cylinder and the top shell are withdrawn, so that the occlusion of the inner groove inside the socket is released. And through the restraint of the minced meat by the socket, the socket separates the minced meat from the rotating cylinder, reducing the possibility of the minced meat collapsing inward, i.e., towards the original position of the rotating cylinder, after the rotating cylinder is removed, and reducing the collapsed voids inside the minced meat. After the rotating cylinder is withdrawn, the near-infrared probe respectively performs multi-point detection inside the detection strip, the socket, and the inner groove. Thus, under the multi-point detection of the inside, outside, and top of the minced meat, the moisture distribution at different depths of the minced meat can be covered, avoiding local errors caused by uneven meat grinding and overall meat blocks, and making the internal moisture detection of the meat more accurate.

[0018] Second, the pressing ring and the socket are manually pushed by the pull rod to move downward into the detection cylinder. Of course, a cylinder can also be added to the pull rod to push the pressing ring and the socket downward. Then, as the socket moves downward, the socket squeezes and pushes the minced meat between the rotating cylinder and the detection cylinder along the rotating cylinder to become thinner, increasing the height of the minced meat but not overflowing the detection cylinder. And as the socket and the pressing ring move downward, the pressing ring will finally press and flatten the top of the minced meat, making the overall minced meat more dense. Thus, the minced meat is constrained by the socket and the pressing ring inside the detection cylinder to form a detection layer with a controllable thickness, i.e., a hollow cylinder.

[0019] Third, the detection strip is arranged outside the detection cylinder, the socket and the pressing ring are respectively arranged inside and on the top of the minced meat, and the detection strip, the socket, and the pressing ring are all made of materials that can transmit near-infrared light, such as quartz glass. Thus, under the restraint of the socket and the pressing ring, the minced meat forms a relatively homogeneous thin sample layer, thereby reducing the transfer consumption and excessive exposure of the minced meat when taken out of the detection cylinder and placed in the sample dish, resulting in moisture evaporation and possible contamination.

[0020] Fourth, when the blade is located in the detection cylinder and rotates, the outer sheet on the outer side of the blade will press and contact the inner wall surface of the detection cylinder as the blade rotates, so that the outer sheet rotates and slides as the blade presses and presses on the surface of the detection cylinder, and the outer sheet connected to the blade can more stably fit the inner wall of the detection cylinder when rotating through the contact and rotation between the outer sheet and the detection cylinder, so that the rotation of the blade is more stable, and a uniform cutting area is formed between the blade and the detection cylinder, so that the minced meat is more delicate, and the surface of the outer sheet is wrapped with a rubber layer, so that the outer sheet is in flexible contact with the detection cylinder through the rubber layer, which reduces the fat inside the meat from being excessively smeared on the detection cylinder and the surface of the detection strip, thereby reducing the impact on subsequent detection.

[0021] 5. When the blade finishes mincing the meat, the hollow clamping rod is driven upward by the push driving source, so that the trigger block at the bottom of the hollow clamping rod, which originally moves downward, releases the constraint state of the extrusion roller and the penetration rod and the blade outward, releases the extrusion compression state of the elastic member, and then the elastic member pulls the extrusion roller to reset, so that the extrusion roller pulls the blade back to the inside of the rotating cylinder, and the outer sheet moves to the inside of the perforation to contact the clamping strip, so that the outer sheet does not protrude from the surface of the rotating cylinder, reducing the degree of flipping of the inside of the detection cylinder when the blade is taken out of the detection cylinder, and avoiding excessive air gaps inside the minced meat.

[0030] As Figures 11 - 14 As shown, a bottom circular plate 2074 is threadedly connected to the bottom of the rotary cylinder 207.

The hollow clamping rod 20611 is composed of a solid column at the top and a hollow column at the bottom. The hollow clamping rod 20611 is movably sleeved on the surface of the central rod 2076 through the hollow column at its bottom.

[0031] As Figures 11 - 14As shown, a number of through holes 2073 are formed on the surface of the rotating cylinder 207. A blade 208 is movably arranged inside the through hole 2073. An outer blade 2081 is fixedly connected to one side of the blade 208 opposite to the rotating cylinder 207. An inner blade 2082 is fixedly connected to one side of the blade 208 opposite to the rotating cylinder 207. The inner contour of the opening of the through hole 2073 is coated with an elastic layer. The surfaces of the outer blade 2081 and the inner blade 2082 are coated with an elastic layer. The elastic layer is preferably an elastic rubber layer. The rotating cylinder 207 is movably connected to the blade 208 through a clamping strip 20731.

And the outer blade 2081 can be received inside the through hole 2073 to block the through hole 2073. The outer contour of the inner blade 2082 fits the inner wall contour of the rotating cylinder 207.

[0032] As Figures 11 - 14 As shown, a number of trigger blocks 20613 are annularly arranged on the surface of the support rod 2011. Clamping plates 20612 are symmetrically arranged on the side of the trigger block 20613. The trigger block 20613 is a right-angled triangular plate. The right-angled part of the trigger block 20613 is arranged on the side opposite to the bottom circular plate 2074. Thus, as the trigger block 20613 moves downward, the width of its surface gradually increases. A constraint rod 2075 is fixedly connected to the inner wall of the rotating cylinder 207. A roller 2084 is movably arranged on the surface of the trigger block 20613. A through rod 2083 is horizontally movably connected to the surface of the constraint rod 2075. The through rod 2083 is fixedly connected to the side of the roller 2084. An elastic member 2085 is sleeved on the surface of the through rod 2083.

The side of the through rod 2083 opposite to the trigger block 20613 movably passes through the constraint rod 2075 and is fixedly connected to the inner blade 2082. The distance between the constraint rod 2075 and the rotating cylinder 207 is greater than the length of the blade 208. The elastic member 2085 is preferably a spring.

[0033] At the connection between the blade 208 and the through-hole 2073, there is a flexible contact with a clamping strip 20731, so that the rubber clamping strip 20731 is distributed along the opening contour of the through-hole 2073, thereby reducing the vibration generated when the blade 208 contacts the meat block during the rotation of the rotating cylinder 207. And the clamping strip 20731 is in flexible contact with the blade 208 to prevent excessive meat paste from entering the inside of the rotating cylinder 207 when the blade 208 retracts into the rotating cylinder 207. When the blade 208 extends into the rotating cylinder 207, the inner blade 2082 fits against the inner wall of the rotating cylinder 207, so that the blade 208 fits against the surface of the rotating cylinder 207 through the rubber layer on its surface to block and restrict the through-hole 2073, reducing the entry of meat paste outside the rotating cylinder 207 into the inside of the rotating cylinder 207; To ensure the cleanliness of the inner wall of the rotating cylinder 207, a water pipe containing high-pressure hot water at a temperature meeting the pasteurization temperature is connected to the through-hole on the surface of the flushing plate 2067, and the bottom circular plate 2074 is rotated to be disengaged from the bottom of the rotating cylinder 207, releasing the threaded connection between the bottom circular plate 2074 and the rotating cylinder 207, so that the opening at the bottom of the rotating cylinder 207 is opened, and then the high-pressure hot water connected to the flushing plate 2067 flushes and disinfects the inside of the rotating cylinder 207. Of course, disinfectant can also be mixed in it for thorough disinfection. After the inside of the rotating cylinder 207 is flushed and disinfected by the high-pressure hot water, the connection between the water pipe and the flushing plate 2067 is released, and the high-pressure hot air pipe is connected to the through-hole on the surface of the flushing plate 2067 to dry the inside of the rotating cylinder 207 with hot air. After the inside of the rotating cylinder 207 is processed, the bottom circular plate 2074 is threadedly connected to the opening at the bottom of the rotating cylinder 207. When the rotating cylinder 207 is flushed with high-pressure water, the blade 208 is retracted into the rotating cylinder 207. If the rotating cylinder 207 needs to be cleaned, disinfectant can be poured into the inside of the detection cylinder 202, the blade 208 is extended out of the surface of the rotating cylinder 207, the inner blade 2082 blocks and closes the through-hole 2073, and the inner blade 2082 rotates with the rotating cylinder 207 in the disinfectant inside the detection cylinder 202 to clean the outside of the detection cylinder 202 and the rotating cylinder 207, and then hot air is used to dry the surfaces of the rotating cylinder 207 and the detection cylinder 202. Operation process: By fixing the bottom plate 201 to the surface of the experimental bench with bolts, then placing small pieces of meat taken from different positions of the meat block into the interior of the detection cylinder 202, and ensuring that the amount of the meat block does not exceed three-fifths of the capacity of the detection cylinder 202. Then, sleeving two hollow sleeve rods 2012 on the surface of the support rod 2011, and making the sealing plates 2013 on the surface of the hollow sleeve rods 2012 rotate and close relatively at the top of the detection cylinder 202, so that a circular opening is formed in the middle where the two sealing plates 2013 are closed. Then, passing the rotating cylinder 207 through the circular opening and placing it into the interior of the detection cylinder 202 and rotating the rotating cylinder 207, so that the blades 208 on the surface of the rotating cylinder 207 push and disperse the meat block inside the detection cylinder 202, reducing the top support of the meat block on the blades 208. Finally, making the docking port 20741 at the bottom of the rotating cylinder 207 be clamped to the top surface of the protruding column 2021 at the bottom of the detection cylinder 202, so that the docking port 20741 can rotate relative to the protruding column 2021. At this time, the support rod 2011 passes through the opening at the top of the top shell 206, and the hollow sleeve rod 2012 supports the top shell 206. Then, thread-fixing the top of the support rod 2011 through the fixing member 1 2063. The socket 204 is pre-sleeved on the surface of the rotating cylinder 207, and the pull rod 2065 is thread-fixed through the fixing member 2 2064, so that the positions of the socket 204 and the top shell 206 are constrained, which is convenient for subsequent rotation and agitation of the meat block inside the detection cylinder 202. During the above process, the blades 208 are received inside the rotating cylinder 207, and the outer piece 2081 enters the inside of the through-opening 2073 to block and close the through-opening 2073, so that the outer piece 2081 does not protrude from the surface of the rotating cylinder 207; Then, making the pushing drive source 2061 drive the hollow clamping rod 20611 to move downward, so that the hollow clamping rod 20611 drives the trigger block 20613 on its surface to contact the roller 2084. And when the trigger block 20613 moves downward with the hollow clamping rod 20611, the width of the contact position between the inclined surface on the surface of the trigger block 20613 and the roller 2084 gradually increases. Thus, the trigger block 20613 gradually pushes the roller 2084 and the through-rod 2083 to move horizontally during the downward movement, and the trigger block 20613 pushes the roller 2084 to compress the elastic member 2085. Thus, the roller 2084 pushes the through-rod 2083 and the blades 208 to move outward. Finally, when the trigger block 20613 moves down to the preset position, the inner piece 2082 fits against the inner wall of the rotating cylinder 207, so that the through-opening 2073 is blocked and closed by the inner piece 2082, and the outer piece 2081 is in extrusion contact with the inner wall of the detection cylinder 202. At this time, the pushing drive source 2061 controls the trigger block 20613 to hover after reaching the preset position through the hollow clamping rod 20611, so that the state of the blades 208 protruding from the rotating cylinder 207 is maintained; Subsequently, start the rotary drive source 2062, and let the rotary drive source 2062 drive the driving wheel 20621 to rotate through its output shaft. Let the driving wheel 20621 drive the driven wheel 2071 to rotate through the transmission member 20622. When the driven wheel 2071 rotates, let the driven wheel 2071 rotate in the installation groove 2066 inside the top shell 206 through the snap ring 2072. Then, when the driven wheel 2071 rotates, it will drive the rotary cylinder 207 to rotate inside the socket 204 and the detection cylinder 202, so that the blade 208 on the surface of the rotary cylinder 207 agitates the meat block inside the detection cylinder 202, making the meat block finer. Finally, after a preset time, let the blade 208 mince and refine the meat block, reducing the volume of the meat block to form minced meat. Of course, in order to reduce the obstruction of the meat block inside the detection cylinder 202 during the extension of the blade 208, the rotary cylinder 207 can be slowly rotated inside the detection cylinder 202 during the extension of the blade 208 to facilitate the extension of the blade 208. Of course, after the hollow sleeve rod 2012 supports the top shell 206, before the first fixing member 2063 is fixed, the space between the rotary cylinder 207 and the detection cylinder 202 is exposed. Then, an operator can add the meat block to be processed into the gap between the blades 208. After the addition is completed, rotate the sealing plate 2013 to fit the surface of the rotary cylinder 207, and then fix the support rod 2011 through the first fixing member 2063; When the blade 208 rotates in the detection cylinder 202, the outer piece 2081 outside the blade 208 will press against and contact the inner wall surface of the detection cylinder 202 as the blade 208 rotates. Thus, the outer piece 2081 rotates while pressing against the surface of the detection cylinder 202 along with the blade 208. Through the contact rotation of the outer piece 2081 and the detection cylinder 202, when the outer piece 2081 connected to the blade 208 rotates, it can more stably fit the inner wall of the detection cylinder 202, making the rotation of the blade 208 more stable, forming a uniform cutting area between the blade 208 and the detection cylinder 202 for the meat block, making the meat mincing effect more delicate. Moreover, the surface of the outer piece 2081 is wrapped with a rubber layer, and the flexible contact between the outer piece 2081 and the detection cylinder 202 through the rubber layer reduces the excessive smearing of the fat inside the meat block on the surfaces of the detection cylinder 202 and the detection strip 203, thus reducing the impact on subsequent detection; When the meat mincing by the blade 208 is completed, the hollow clamping rod 20611 is pushed by the driving source 2061 to rise, so that the triggering block 20613 at the bottom of the hollow clamping rod 20611 is released from the original downward movement to squeeze the roller 2084, the through rod 2083 and the outward constraint state of the blade 208, and the squeezing and compressing state of the elastic member 2085 is released. Furthermore, the elastic member 2085 pulls the squeezing roller 2084 to reset, the squeezing roller 2084 pulls the blade 208 to retract into the rotating cylinder 207, the outer blade 2081 moves to the inside of the through hole 2073 and contacts the clamping strip 20731, so that the outer blade 2081 does not protrude from the surface of the rotating cylinder 207, reducing the degree of turning inside the detection cylinder 202 when the blade 208 is taken out from the detection cylinder 202, and avoiding the generation of too large air gaps inside the minced meat. Embodiment 2: The difference between this embodiment and the first embodiment is: As Figure 4 and Figures 9 - 10 shown, a pull rod 2065 is fixedly connected to the top of the socket 204, the pull rod 2065 passes through the top shell 206 and is threadedly connected to the fixing member two 2064. The fixing member one 2063 and the fixing member two 2064 are preferably nut sleeves, and the parts of the support rod 2011 and the pull rod 2065 protruding from the top shell 206 are provided with threads matching the nut sleeves; An inclined mouth ring 2041 is provided around the bottom of the socket 204 to reduce the resistance of the socket 204 moving downward in contact with the minced meat. An inner groove 2042 is provided inside the socket 204, and the inner groove 2042 is movably sleeved on the surface of the rotating cylinder 207. The pressing ring 205, the socket 204 and the detection strip 203 are made of materials that can transmit near-infrared light, preferably sapphire or low-hydroxyl quartz glass.

[0034] The detection strip 203 is a rectangular plate or an arc-shaped plate. When the detection strip 203 is an arc-shaped plate, the arc degree of the detection strip 203 is the same as that of the detection cylinder 202, so that the detection strip 203 and the detection cylinder 202 form a circle, facilitating the sliding of the outer blade 2081 on the inner walls of the detection cylinder 202 and the detection strip 203; when the detection strip 203 is a rectangular plate, the inner wall of the rectangular detection strip 203 and the arc-shaped inner wall of the detection cylinder 202 are connected by a radian fillet, and the distance between the inner wall of the detection strip 203 and the surface of the rotating cylinder 207 is closer than the distance between the inner wall of the detection cylinder 202 and the surface of the rotating cylinder 207. Furthermore, when the outer blade 2081 rotates inside the detection cylinder 202, it will pass through the inner wall of the detection strip 203, and the inner wall of the detection strip 203 squeezes the elastic layer on the surface of the outer blade 2081 to retract, thereby reducing the interference of the protrusion of the detection strip 203 to the sliding of the outer blade 2081 on the inner walls of the detection cylinder 202 and the detection strip 203, and meeting the requirements of the near-infrared probe 101 for the measurement mode selection through two different shapes of the detection strip 203.

[0035] The remaining structures are the same as those in the first embodiment.

[0036] Operation process: After the blade 208 is received inside the rotating cylinder 207, release the threaded connection of the first fixing member 2063 to the support rod 2011, then manually lift the top shell 206 to release the restraint of the hollow sleeve rod 2012, and then rotate the hollow sleeve rod 2012 to drive the sealing plates 2013 connected thereto to move away from each other on the surface of the support rod 2011, so as to release the occlusion of the top of the detection cylinder 202 by the sealing plates 2013; Furthermore, rotate the second fixing member 2064 to release the restraint on the pull rod 2065, so that the pressing ring 205 and the socket 204 are manually pushed by the pull rod 2065 to move downward into the detection cylinder 202. Of course, a cylinder can also be added to the pull rod 2065 to push the pressing ring 205 and the socket 204 to move downward. Then, as the socket 204 moves downward, the socket 204 squeezes and pushes the minced meat between the rotating cylinder 207 and the detection cylinder 202 along the rotating cylinder 207 to become thinner, so that the height of the minced meat rises but does not overflow from the detection cylinder 202. And as the socket 204 and the pressing ring 205 move downward, the pressing ring 205 will finally press and flatten the top of the minced meat, making the overall minced meat more dense, so that the minced meat is constrained by the socket 204 and the pressing ring 205 inside the detection cylinder 202 to form a detection layer with a controllable thickness, that is, a hollow cylinder. Of course, the detection cylinder 202 and the socket 204 can also be manually tapped with a rubber hammer to make the two vibrate, further improving the distribution uniformity and density of the minced meat between the socket 204, the pressing ring 205 and the detection cylinder 202. Different sockets 204 with different thicknesses can be replaced to make the thickness of the minced meat sample relatively controllable for different detection needs; The detection strip 203 is arranged outside the detection cylinder 202, the socket 204 and the pressing ring 205 are respectively arranged inside and on the top of the minced meat, and the detection strip 203, the socket 204 and the pressing ring 205 are all made of materials that can transmit near-infrared light, such as quartz glass. Thus, under the restraint of the socket 204 and the pressing ring 205, the minced meat forms a relatively homogeneous thin sample layer, thereby reducing the transfer consumption of the minced meat when taken out of the detection cylinder 202 and placed in the sample dish, the water evaporation caused by excessive exposure, and the possible contamination introduced. Of course, in order to reduce the heat interference caused by the rotation of the blade 208, before the blade 208 contacts the meat block, the equipment can be pre-cooled and frozen to reduce the surface temperature of the equipment to four degrees. And the detection strip 203 is provided to avoid the relative intensity decrease caused by the detection cylinder 202 being made of materials that can transmit near-infrared light, and the material of the detection cylinder 202 is the material of the meat grinding cylinder of a conventional meat grinder, such as stainless steel or toughened glass; After the socket 204 is inserted into the minced meat, the rotary cylinder 207 and the top shell 206 are withdrawn, so that the occlusion of the inner groove 2042 inside the socket 204 is released, and due to the restraint of the minced meat by the socket 204, the socket 204 separates the minced meat from the rotary cylinder 207, reducing the possibility of the minced meat collapsing inward, i.e., towards the original position of the rotary cylinder 207, after the rotary cylinder 207 is removed, and reducing the collapse gap inside the minced meat. After the rotary cylinder 207 is withdrawn, the near-infrared probe 101 performs multi-point detection inside the detection strip 203, the socket 204, and the inner groove 2042 respectively. Thus, under the multi-point detection of the inside, outside, and top of the minced meat, the moisture distribution at different depths of the minced meat can be covered, avoiding local errors caused by uneven mincing and uneven whole meat blocks, and making the internal moisture detection of the meat more accurate.
