Description

Technical Field

[0001] This invention relates to the field of edible meat processing technology, specifically to a high-frequency vibration cutting device for beef processing to prevent sticking. Background Technology

[0002] The high-frequency vibration cutting device is a meat processing equipment that directly applies high-frequency mechanical vibration to the cutting blade body to achieve beef dicing through low-resistance impact cutting. The cutting device relies on the high-frequency reciprocating vibration of the blade assembly (driven by an eccentric shaft and a vibration motor) in conjunction with belt conveyor feeding, and can complete the dicing process without freezing and shaping the beef.

[0003] When processing beef using a high-frequency vibrating cutting device, workers first remove large bones, hard fascia, and obvious foreign objects from the beef, trimming it into roughly flat pieces to prevent damage to the blade assembly. The beef is then laid flat on the conveyor belt at the feed end of the equipment. The conveyor belt carries the beef into the cutting chamber at a uniform speed, with side baffles restricting lateral movement and ensuring aligned cuts. The beef first passes through a longitudinal vibrating blade grid, where the high-frequency reciprocating vibration of the blade assembly cuts the entire piece of beef into uniformly wide strips. The strips continue forward on the conveyor belt, passing through high-speed reciprocating transverse cutters. These transverse cutters, perpendicular to the direction of the strips, vibrate at high frequency, cutting the strips into cubic / rectangular cubes. The shaped cubes are then conveyed out from the discharge end of the equipment and fall directly into a receiving container, completing a single processing cycle.

[0004] However, soft, thawed meat and high-fat meat have low strength, are easily deformed, and are highly lubricated. The force exerted by the blade is mostly converted into material deformation and slippage, failing to achieve effective shearing. This results in an increased proportion of minced meat and scraps in the finished product, leading to large fluctuations in yield. Therefore, we propose a high-frequency vibration cutting device for beef processing to prevent sticking. Summary of the Invention

[0005] The purpose of this invention is to provide a high-frequency vibration cutting device for beef processing to prevent sticking, thereby solving the problems mentioned in the background art, such as the low strength, easy deformation, and strong lubricity of soft thawed meat and high-fat meat, where the force of the blade is mostly converted into material deformation and slippage, failing to form effective shearing, resulting in an increase in the proportion of minced meat and scraps in the finished product and large fluctuations in yield.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-frequency vibration cutting device for beef processing to prevent sticking, comprising a conveyor line and a cutting device housing; and further comprising a support base, which is fixed to the inner wall of the cutting device housing by bolts, and the support base is located at the feeding end of the cutting device housing; The pretreatment component is located at the bottom of the support base. The pretreatment component treats the residual water stains on the surface of the beef after the beef pieces enter the housing of the cutting device. Temperature measuring component, located at the bottom of the support base, detects the temperature of the upper surface of the beef after the pretreatment component and measures the unevenness of the upper surface of the beef. The condensing component is located at the bottom of the support base. The pretreatment component, temperature measuring component and condensing component are distributed in sequence. The condensing component is connected to the temperature measuring component and condenses the upper surface of the beef. The higher the surface temperature of the beef detected by the temperature measuring component and the greater the thickness of the beef, the lower the temperature of the cold air blown onto the beef by the condenser component.

[0007] The pretreatment component includes multiple support cylinders, which are coaxially distributed. Two support cylinders at both ends are fixed to the inner wall of the support base. A rotating cylinder is rotatably connected between two adjacent support cylinders. Multiple fixed cylinders are fixedly connected to the outside of the rotating cylinder. The multiple fixed cylinders are equidistantly distributed on the outside of the rotating cylinder. The inner wall of the fixed cylinder is provided with a water-absorbing component, and the inner side of the support cylinder is provided with a switching component for switching the water-absorbing component.

[0008] The absorbent component includes a fixed frame that is slidably connected to the inner wall of the fixed cylinder, a return spring that is fixedly connected between the fixed frame and the fixed cylinder, and an absorbent cotton swab that is fixedly connected to one end of the fixed frame that extends out of the fixed cylinder.

[0009] The switching component includes a rotating shaft located on the inner wall of the support cylinder. The rotating shaft is coaxial with the support cylinder and rotatably connected to the inner wall of the support base. A servo motor is installed on the inner wall of the support base. The output end of the servo motor is fixed to the rotating shaft. Multiple transmission discs are fixedly connected to the outer side of the rotating shaft. The multiple transmission discs correspond to the positions of multiple rotating cylinders respectively. A synchronization component is provided between the transmission discs and the rotating cylinders. A limit switch is installed on the inner wall of the fixed cylinder. A controller is installed on the inner wall of the support cylinder. The controller is connected to the multiple limit switches. When the absorbent cotton swab located directly below the rotating cylinder is saturated with water, it drives the fixed frame to trigger the limit switch. The controller controls the synchronization component and the servo motor to work. When the servo motor drives the rotating shaft to rotate, the transmission disk drives the rotating cylinder to rotate through the synchronization component. The rotating cylinder drives the fixed cylinder to rotate, and the unused absorbent cotton swab rotates to the bottom of the rotating cylinder.

[0010] The synchronizing component includes a synchronizing plate located between the rotating cylinder and the transmission disc. The inner wall of the rotating cylinder has a snap-fit ​​groove. The end of the synchronizing plate near the rotating cylinder is slidably connected to the inner wall of the snap-fit ​​groove. The outer side of the transmission disc has a limiting groove. The end of the synchronizing plate near the transmission disc is slidably connected to the inner wall of the limiting groove. The limiting groove includes a rotating end and multiple snap-fit ​​ends. The spacing between the multiple snap-fit ​​ends is the same as the spacing between the multiple fixed cylinders. An electric telescopic rod is fixedly connected to the inner wall of the support cylinder. A movable plate is rotatably connected to the outer side of the synchronizing plate. The output end of the electric telescopic rod is fixedly connected to the movable plate. The electric telescopic rod is connected to the controller.

[0011] The temperature measuring component includes multiple support columns, which are fixedly connected to the bottom of the support base. A contact rod is slidably connected to the inner wall of the support column, and a thermistor is fixedly connected to the bottom end of the contact rod. The temperature sensing surface of the thermistor faces downward. A sliding rheostat is installed on the inner wall of the support column. The contact rod is connected to the slider of the sliding rheostat. A compression spring is fixedly connected between the contact rod and the support column. The thermistor is connected in series in the circuit where the sliding rheostat is located.

[0012] The condensation assembly includes multiple vortex tubes, which are fixedly connected to the inner wall of the support base. Each vortex tube corresponds to a support column. A compressor is installed on the outside of the cutting device housing. The output end of the compressor is connected to a three-stage precision filter. The output end of the three-stage precision filter is connected to a gas supply pipe. A gas distribution box is fixedly connected to the top of the support base. The gas supply pipe passes through the cutting device housing and connects to the gas distribution box. Multiple gas injection pipes are connected to the outside of the gas distribution box. Each gas injection pipe corresponds to a vortex tube. A solenoid valve is installed on the outside of the gas injection pipe. A nozzle is fixedly connected to the cold end of the vortex tube. The outlet of the nozzle faces downward. A control for adjusting the temperature of the cold airflow is provided on the outside of the hot end of the vortex tube.

[0013] The control unit includes a support frame fixedly connected to the hot end of the vortex tube. A conical plug is slidably connected to the inner wall of the support frame. The conical end of the conical plug is close to the outlet of the vortex tube. An adjusting rod is fixedly connected to the end of the conical plug away from the vortex tube. The adjusting rod is slidably connected to the inner wall of the support frame. An armature is fixedly connected to the end of the adjusting rod away from the conical plug. An electromagnet is installed on the inner wall of the support frame. A second return spring is sleeved on the outer side of the adjusting rod. One end of the second return spring is fixed to the conical plug, and the other end of the second return spring is fixed to the inner wall of the support frame.

[0014] Along the airflow direction, the inner diameter of the nozzle channel has a conical converging structure from the air inlet to the air outlet.

[0015] In this circuit, the sliding rheostat and the thermistor are connected in series with the electromagnet. When the resistance of the sliding rheostat or the thermistor decreases, the attraction force of the electromagnet on the armature increases, the conical plug approaches the eddy current tube, the exhaust channel of the hot end of the eddy current tube narrows, and the temperature of the cold air discharged from the cold end of the eddy current tube decreases.

[0016] This invention has at least the following beneficial effects: When used, this application uses a pre-treatment component to treat residual water stains on the surface of beef, preventing surface water stains from freezing into an ice shell, reducing cutting fragments and sticking to the knife. Furthermore, a temperature measuring component performs zoned detection on the surface of the beef to be cut. By detecting the surface temperature and thickness of the beef, the condensation component performs zoned adaptive cooling on the beef surface, allowing a micro-frozen hardened layer to quickly form on the surface of the beef and maintaining a uniform thickness of the hardened layer. This provides stable cutting rigidity support for soft, thawed meat and high-fat meat, reducing the proportion of meat scraps and chips. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0020] Please see Figures 1 to 10 This invention provides a technical solution: a high-frequency vibration cutting device for beef processing to prevent sticking, comprising a conveyor line 1 and a cutting device housing 2; a support base 3, which is fixed to the inner wall of the cutting device housing 2 by bolts, and is located at the feeding end of the cutting device housing 2; a pretreatment component 4, located at the bottom of the support base 3, which treats residual water stains on the surface of the beef after the beef pieces enter the cutting device housing 2, preventing surface icing during subsequent cooling and reducing sticking during cutting; a temperature measuring component 5, located at the bottom of the support base 3, which detects the temperature of the upper surface of the beef after passing through the pretreatment component 4 and measures the unevenness of the upper surface of the beef; and a condensing component 6, located at the bottom of the support base 3. The pretreatment component 4, temperature measuring component 5, and condensing component 6 are distributed sequentially, and the condensing component 6 is connected to the temperature measuring component 5, which condenses the upper surface of the beef; the higher the upper surface temperature of the beef detected by the temperature measuring component 5 and the greater the thickness of the beef, the lower the temperature of the cold air blown onto the beef by the condensing component 6.

[0021] In use, the deboned and trimmed beef chunks are laid flat on the conveyor line 1 and conveyed into the cavity of the cutting device housing 2 by the conveyor belt at a uniform speed. First, they enter the pre-treatment station below the support base 3, where the pre-treatment component 4 removes the residual water stains on the surface of the beef. After the water is removed, the beef enters the temperature measuring station with the conveyor belt. The temperature measuring component 5 performs zoned detection on the surface of the beef to be cut. The beef continues to enter the condensation station. Based on the detected surface temperature and thickness of the beef, the condensation component 6 performs zoned adaptive cooling on the surface of the beef, so that a micro-frozen hardened layer is quickly formed on the surface.

[0022] For the raised parts of the beef with high surface temperature and large thickness, the condenser component 6 outputs cold air with a lower temperature to enhance cooling; For the concave parts of beef that are cold and thin, the condenser component 6 outputs cold air at a higher temperature to prevent over-freezing and preserve the freshness inside. This process creates a uniformly thick hardened surface layer on the beef to be cut, while maintaining a chilled state of 0-4℃ inside, thus balancing the rigid support during cutting with the freshness of the product.

[0023] The beef, after its surface hardening is completed, continues to move forward with the conveyor belt, passing in sequence through the longitudinal vibrating blade grid and the transverse vibrating cutter. The high-frequency reciprocating blade assembly completes the dicing process. The surface hardening layer provides stable rigid support for cutting, effectively reducing material deformation, slippage, and adhesion to the blade. The shaped meat cubes are sent out from the discharge end with the conveyor belt and fall into the receiving container.

[0024] The pretreatment component 4 includes multiple support cylinders 40, which are coaxially distributed. Two support cylinders 40 at both ends are fixed to the inner wall of the support base 3. A rotating cylinder 41 is rotatably connected between two adjacent support cylinders 40, so that the rotating cylinder 41 can rotate freely around its own axis. Multiple fixed cylinders 42 are fixedly connected to the outside of the rotating cylinder 41. The multiple fixed cylinders 42 are equidistantly distributed on the outside of the rotating cylinder 41. The inner wall of the fixed cylinder 42 is provided with a water-absorbing element 43. The inner side of the support cylinder 40 is provided with a switching element 44 for switching the water-absorbing element 43.

[0025] The absorbent component 43 includes a fixed frame 45 that is slidably connected to the inner wall of the fixed cylinder 42. A return spring 46 is fixedly connected between the fixed frame 45 and the fixed cylinder 42. An absorbent cotton swab 47 is fixedly connected to one end of the fixed frame 45 that extends out of the fixed cylinder 42. The absorbent cotton swab 47 is a food-grade hydrophilic degreasing cotton swab. The surface of the absorbent cotton swab 47 is smooth and there is no fiber shedding. It can efficiently absorb free water and will not snag beef fibers. It is a standardized and replaceable consumable. The return spring 46 pushes the fixing bracket 45 outward under normal conditions, providing a stable pre-tightening pressure for the absorbent cotton swab 47, so that the absorbent cotton swab 47 always gently presses against the surface of the beef; at the same time, it has a telescopic allowance, which can adapt to the undulations of the beef surface and avoid damaging the soft meat tissue.

[0026] The switching component 44 includes a rotating shaft 48 located on the inner wall of the support cylinder 40. The rotating shaft 48 is coaxially arranged with the support cylinder 40 and rotatably connected to the inner wall of the support base 3. A servo motor 49 is installed on the inner wall of the support base 3. The output end of the servo motor 49 is fixed to the rotating shaft 48. Multiple transmission discs 410 are fixedly connected to the outer side of the rotating shaft 48. The multiple transmission discs 410 correspond to the positions of multiple rotating cylinders 41 respectively. A synchronization component 411 is provided between the transmission discs 410 and the rotating cylinders 41. A limit switch 412 is installed on the inner wall of the fixed cylinder 42. A controller 413 is installed on the inner wall of the support cylinder 40. The controller 413 is connected to the multiple limit switches 412.

[0027] Under normal conditions, the return spring 46 pushes the fixed frame 45 outward. When it is not in contact with the beef, the absorbent cotton swab 47 located directly below the rotating cylinder 41 pulls down the fixed frame 45 under its own weight. The fixed frame 45 stretches the return spring 46. When the absorbent cotton swab 47 is not saturated with water, the movement distance of the fixed frame 45 is insufficient to trigger the limit switch 412. When the absorbent cotton swab 47 is saturated with water, the absorbent cotton swab 47 drives the fixed frame 45 to trigger the limit switch 412, and the limit switch 412 outputs a saturation detection signal to the controller 413.

[0028] Synchronizing component 411 includes a synchronizing plate 414 located between rotating cylinder 41 and transmission disk 410. A snap-fit ​​groove 415 is provided on the inner wall of rotating cylinder 41. The end of synchronizing plate 414 near rotating cylinder 41 is slidably connected to the inner wall of snap-fit ​​groove 415. A limiting groove 416 is provided on the outer side of transmission disk 410. The end of synchronizing plate 414 near transmission disk 410 is slidably connected to the inner wall of limiting groove 416. Limiting groove 416 includes a rotating end 417 and multiple snap-fit ​​ends 418. The spacing between multiple snap-fit ​​ends 418 is the same as the spacing between multiple fixed cylinders 42. An electric telescopic rod 419 is fixedly connected to the inner wall of support cylinder 40. A moving plate 420 is rotatably connected to the outer side of synchronizing plate 414 through bearings. Moving plate 420 and synchronizing plate 414 move synchronously along the rotation axis. The output end of electric telescopic rod 419 is fixedly connected to moving plate 420. Electric telescopic rod 419 is connected to controller 413.

[0029] The controller 413 is electrically connected to all limit switches 412, electric telescopic rod 419, and servo motor 49. When the absorbent cotton swab 47 is not saturated with water, the electric telescopic rod 419 is in the retracted position. The electric telescopic rod 419 drives the moving plate 420 to move, so that the synchronous plate 414 disengages from the locking end 418 of the limiting groove 416 in the transmission disc 410. The synchronous plate 414 is in the rotating end 417 of the limiting groove 416. The synchronous plate 414 is only locked to the rotating cylinder 41 through the locking groove 415. At this time, the rotating cylinder 41 is in a free state and is not linked with the rotating shaft 48.

[0030] When the absorbent cotton swab 47 at any workstation triggers the limit switch 412, the controller 413 first controls the corresponding electric telescopic rod 419 to extend. The electric telescopic rod 419 pushes the moving plate 420 to move, and the moving plate 420 pushes the synchronous plate 414 to move, so that the synchronous plate 414 slides from the rotating end 417 of the limiting groove 416 to the snap-fit ​​end 418 of the limiting groove 416, so that the transmission disc 410 and the rotating cylinder 41 are circumferentially locked. Then the servo motor 49 is started to rotate at the set angle. At this time, the servo motor 49 drives the rotating shaft 48 to rotate, which can drive the rotating cylinder 41 to rotate synchronously through the transmission disc 410 and the synchronous plate 414, so that the next set of drying absorbent cotton swabs 47 can be rotated to the working position directly below.

[0031] The temperature measuring component 5 includes multiple support columns 50, which are fixedly connected to the support base 3 below. A contact rod 51 is slidably connected to the inner wall of the support column 50. A thermistor 52 is fixedly connected to the bottom end of the contact rod 51, with the temperature sensing surface of the thermistor 52 facing downward. A sliding rheostat 53 is installed on the inner wall of the support column 50. The contact rod 51 is connected to the slider of the sliding rheostat 53. A compression spring 54 is fixedly connected between the contact rod 51 and the support column 50. The thermistor 52 is connected in series in the circuit where the sliding rheostat 53 is located.

[0032] The thermistor 52 is an NTC negative temperature coefficient thermistor 52, whose resistance decreases as the temperature increases. The higher the surface temperature of the beef, the lower the resistance of the thermistor 52 and the larger the circuit current.

[0033] When the surface of the beef is raised and the thickness increases, the push rod 51 is pushed to retract upward, causing the slider to move upward. The length of the resistance wire of the sliding rheostat 53 connected to the circuit is shortened, the resistance value decreases, and the loop current increases. Conversely, when the surface is concave and the thickness is small, the resistance value increases and the loop current decreases.

[0034] Since the thermistor 52 and the sliding rheostat 53 are connected in series in the same power supply circuit, the total circuit current is determined by two parameters: temperature and thickness. The higher the temperature and the greater the thickness of the beef, the smaller the total resistance of the circuit and the greater the output current. This achieves the fusion feedback of the two parameters, which can directly drive the subsequent cooling capacity adjustment without the need for an additional calculation unit.

[0035] The condenser assembly 6 includes multiple vortex tubes 60, which are fixedly connected to the inner wall of the support base 3. Each vortex tube 60 corresponds to a support column 50. A compressor 61 is installed on the outside of the cutting device housing 2. The output end of the compressor 61 is connected to a three-stage precision filter 62. The output end of the three-stage precision filter 62 is connected to a gas supply pipe 63. A gas distribution box 64 is fixedly connected to the top of the support base 3. The gas supply pipe 63 passes through the cutting device housing 2 and connects to the gas distribution box 64. Multiple gas injection pipes 65 are connected to the outside of the gas distribution box 64. Each gas injection pipe 65 corresponds to a vortex tube 60. A solenoid valve 66 is installed on the outside of the gas injection pipe 65, which can control the single-path on / off state individually, facilitating maintenance and zone start / stop. A nozzle 67 is fixedly connected to the cold end of the vortex tube 60. The outlet of the nozzle 67 faces downward. A control 68 for adjusting the temperature of the cold airflow is provided on the outside of the hot end of the vortex tube 60.

[0036] The adjustment control 68 includes a support frame 69 fixedly connected to the hot end tube of the vortex tube 60. A conical plug 610 is slidably connected to the inner wall of the support frame 69. The conical end of the conical plug 610 is close to the outlet of the vortex tube 60. An adjustment rod 611 is fixedly connected to the end of the conical plug 610 away from the vortex tube 60. The adjustment rod 611 is slidably connected to the inner wall of the support frame 69. An armature 612 is fixedly connected to the end of the adjustment rod 611 away from the conical plug 610. An electromagnet 613 is installed on the inner wall of the support frame 69. A second return spring 614 is sleeved on the outer side of the adjustment rod 611. One end of the second return spring 614 is fixed to the conical plug 610, and the other end of the second return spring 614 is fixed to the inner wall of the support frame 69. The sliding rheostat 53 and the thermistor 52 are connected in series with the electromagnet 613 in the same power supply circuit. When the resistance of the sliding rheostat 53 or the thermistor 52 decreases, the attraction force of the electromagnet 613 on the armature 612 increases, the conical plug 610 approaches the eddy tube 60, the exhaust channel of the hot end tube of the eddy tube 60 narrows, and the temperature of the cold air discharged from the cold end tube of the eddy tube 60 decreases.

[0037] In use, the compressed air generated by the compressor 61 is purified by a three-stage precision filter 62. The purified compressed air is then connected to the air distribution box 64 on the top of the support base 3 through the air delivery pipe 63. The air distribution box 64 has a large-volume pressure-stabilizing cavity inside, which evenly distributes the main airflow to multiple air injection pipes 65. The air injection pipes 65 inject compressed gas into the vortex tube 60. After the compressed air enters the vortex tube 60, it forms a high-speed swirling flow through the tangential nozzle inside the vortex tube 60. The cold and hot flow is achieved by relying on the energy separation effect of the airflow itself: the inner low-temperature airflow is output downward from the cold end pipe, and the outer high-temperature airflow is discharged from the hot end pipe.

[0038] Each hot end tube of the vortex tube 60 is equipped with a set of adjustment control 68, which is directly driven by the front temperature measurement circuit. When the beef temperature is high and the thickness is large, the total resistance of the temperature measurement circuit is small and the current is large. The attraction of the electromagnet 613 to the armature 612 is enhanced, which overcomes the elastic force of the reset spring 614 and pulls the conical plug 610 to move towards the hot end outlet of the vortex tube 60, reducing the gap of the exhaust channel. The exhaust volume of the hot end of the vortex tube 60 is reduced and the cold flow ratio is reduced. The temperature of the cold air output at the cold end is reduced, which strengthens the cooling intensity of the area and ensures the formation of a hardened layer of sufficient thickness. When the beef temperature is low and the thickness is small, the total resistance of the temperature measuring circuit is high and the current is low. The attraction of the electromagnet 613 weakens, the reset spring pushes the conical plug 610 to move outward, opening the exhaust channel, increasing the cold flow ratio, and the cold air temperature output at the cold end increases accordingly, avoiding overfreezing in this area and maintaining the fresh-cut properties inside. Through this purely hardware feedback mechanism, each vortex tube 60 can independently and in real time adjust the cooling capacity according to the temperature and thickness of the beef in the corresponding area, ultimately making the surface hardened layer of the entire piece of beef uniform in thickness. Example 2

[0039] In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that, along the airflow direction, the inner diameter of the nozzle 67 channel has a converging structure from the air inlet end to the air outlet end. On the one hand, this can increase the cold air outlet velocity, increase the convective heat transfer coefficient of the beef surface, and accelerate the surface hardening speed. On the other hand, it can constrict the airflow, reduce lateral diffusion, reduce airflow crosstalk between adjacent nozzles, improve the accuracy of zoned cooling, and allow the cooling energy to be precisely applied to the corresponding area.
