Detailed implementation method

[0017] Such as Figures 1-4As shown in the figure, a low-temperature coupling tenderizing device for squid includes a protection box 10. A sealed box cover 11 is fixedly installed on the protection box 10. A controller 13 is fixedly installed on the left side of the protection box 10. A temperature control mechanism 20 is arranged on the left side of the protection box 10. The temperature control mechanism 20 includes a U-shaped groove 204 opened at the bottom of the protection box 10, and the U-shaped groove 204 penetrates through the left side plate, bottom plate and right side plate inside the protection box 10. A pump 202 is fixedly connected to the left side of the protection box 10. The input end of the pump 202 is connected to a liquid cooling box 201 through a pipeline. The liquid cooling box 201 is fixedly connected to the protection box 10. The output end of the pump 202 is fixedly connected to a liquid cooling pipe 203. The liquid cooling pipe 203 penetrates through the surface of the protection box 10 and is fixed on the inner surface of the U-shaped groove 204 in a U-shaped path from back to front. The other end of the liquid cooling pipe 203 is fixedly communicated with the liquid cooling box 201.

[0018] Preferably, a tray rack 12 is arranged inside the protection box 10. A group of trays are built in the tray rack 12. A plurality of water permeable holes are opened on the top surface of the tray. An ultrasonic generating device 14 is fixedly installed on the front side inside the protection box 10. The ultrasonic generating device 14 is electrically connected to the controller 13. Before use, place the squid on each tray in turn, then open the sealed box cover 11, insert the tray rack 12 into the hole groove reserved at the bottom of the protection box 10 in a plug-in manner, and then close the sealed box cover 11. Then the controller 13 starts the ultrasonic generating device 14 through an external power supply. The ultrasonic generating device 14 emits ultrasonic waves to the tray rack 12. By using the mechanical effect and cavitation effect of ultrasonic waves, the structure of myofibrillar protein in the muscle tissue of squid is changed, and the release of myofibrillar protein is promoted, so as to improve the physical and chemical properties such as water holding capacity and tenderness of squid.

[0019] Specifically, a semiconductor refrigeration sheet 205 is fixedly installed on the left side of the liquid cooling box 201. The left side of the protection box 10 is connected to a housing 206 through a fastener. A temperature sensor 207 is arranged on the bottom side of the sealed box cover 11. The semiconductor refrigeration sheet 205, the pump 202 and the temperature sensor 207 are electrically connected to the controller 13.

[0020] When tenderizing squid, the temperature is generally controlled within the range of 0-10°C to meet the requirements of low-temperature tenderization of squid. The low-temperature environment helps to maintain the quality and freshness of squid, while slowing down the activity of enzymes and preventing squid from deteriorating during the tenderization process. Therefore, the temperature control mechanism 20 is activated through the controller 13. The temperature control mechanism 20 first monitors the temperature inside the protection box 10 through the temperature sensor 207. Then, after the controller 13 receives a signal that the temperature exceeds the range, it sends a start command to the semiconductor refrigeration chip 205. The semiconductor refrigeration chip 205 starts to work, refrigerating and cooling the coolant in the liquid cooling box 201 to keep the coolant at a relatively low temperature. At the same time, the controller 13 also sends a start command to the first pump 202. The first pump 202 starts to operate. Its input end extracts low-temperature coolant from the liquid cooling box 201 through a pipeline. The first pump 202 transports the extracted coolant to the liquid cooling pipe 203 through the output end. The coolant 203 circulates in the liquid cooling pipe, exchanges heat with the inside of the protection box 10, absorbs the heat inside the protection box 10, thereby reducing the temperature inside the protection box 10. The coolant after heat exchange flows back to the liquid cooling box 201 from the other end of the liquid cooling pipe 203 and is refrigerated and cooled by the semiconductor refrigeration chip 205 again, forming a cyclic refrigeration process. When the temperature sensor 207 monitors that the temperature inside the protection box 10 drops to the temperature value set by the controller 13, after the controller 13 receives a signal that the temperature has reached the set value, it sends stop commands to the semiconductor refrigeration chip 205 and the first pump 202. The semiconductor refrigeration chip 205 stops refrigerating, the first pump 202 stops operating, and the coolant stops circulating. Thus, the effect of controlling the temperature inside the protection box 10 is achieved.

[0021] Reference Figure 1 、 Figure 2 、 Figure 5 、 Figure 8 、 Figure 9 A liquid spraying mechanism 30 is provided on the left side of the protection box 10. The temperature control mechanism 20 includes a liquid storage tank 301 fixedly connected to the left side of the protection box 10. A liquid injection pipeline is provided at the top of the liquid storage tank 301; a second pump 302 is provided at the top of the liquid storage tank 301. The output end of the second pump 302 is connected to the inside of the liquid storage tank 301 through a pipeline. The output end of the second pump 302 is fixedly connected to a connecting pipe 303. The other end of the connecting pipe 303 is fixedly connected to a fixed pipe 304. The left side of the fixed pipe 304 is fixedly connected to the inside of the protection box 10. The right side of the fixed pipe 304 is fixedly connected to a folding hose 305. A spray assembly 40 that can move left and right is provided on the right side of the folding hose 305; the second pump 302 is electrically connected to the controller 13.

[0022] Specifically, the spraying assembly 40 includes a connecting block 401. A rotating rod 402 is rotatably connected to the right side of the connecting block 401. A turning plate 405 is fixedly connected to the right side of the rotating rod 402. A pair of liquid outlet boxes 406 that are vertically mirror-symmetrical are fixedly connected to the right side of the turning plate 405. A group of spray nozzles are fixedly installed inside the pair of liquid outlet boxes 406. A connecting pipe 407 is fixedly communicated with the front side of the pair of liquid outlet boxes 406. The folding hose 305 is fixedly communicated with the corresponding pair of connecting pipes 407 through a shunt head.

[0023] Preferably, a fixing ring 403 is fixedly connected to the right side of the connecting block 401. A volute spring is arranged inside the fixing ring 403. The outer end of the volute spring is fixedly connected to the fixing ring 403. The inner end of the volute spring is fixedly connected to the outer side of the rotating rod 402; thus, the support for the angle of the rotating rod 402 is achieved, so that the turning plate 405 maintains a vertical state under normal conditions.

[0024] During the process of low-temperature coupling tenderization treatment, first, low-temperature treatment is carried out, and then the tenderizing liquid is sprayed onto the surface of the squid through the liquid spraying mechanism 30; at this time, the controller 13 starts the second pump body 302 through an external power supply. The input end of the second pump body 302 extracts the tenderizing liquid inside the liquid storage tank 301 through a pipeline, and then flows through the output end of the second pump body 302 to the connecting pipe 303, and respectively flows to a group of folding hoses 305 through the connecting pipe 303 and the fixed pipe 304, and then flows into the liquid outlet box 406 through the connecting pipe 407, and finally the tenderizing liquid is sprayed out through the spray nozzles.

[0025] Further, referring to Figures 5-10 , a winding and unwinding mechanism 50 is arranged at the rear side of the spraying assembly 40. The winding and unwinding mechanism 50 includes a moving groove 501 opened inside the rear side plate of the protection box 10. A threaded rod 503 is rotatably connected to the left and right sides inside the moving groove 501. A moving frame 504 is threadedly connected to the outer side of the threaded rod 503. The moving frame 504 includes a vertical plate connected to the threaded rod 503 and horizontal plates fixedly connected to the upper and lower ends of the vertical plate respectively. A pair of guiding grooves 508 arranged vertically are opened at the rear side inside the protection box 10. The guiding grooves 508 communicate with the moving groove 501. The horizontal plates are slidably connected to the corresponding guiding grooves 508. A connecting rod 505 is rotatably connected to the inner sides of the pair of horizontal plates. The connecting rod 505 is fixedly connected to a group of connecting blocks 401; a second gear 506 is fixedly connected to the bottom of the connecting rod 505. A second toothed plate 507 is meshed with the front side of the second gear 506. The left side of the second toothed plate 507 is fixedly connected to the protection box 10; a motor 502 is fixedly connected to the left side of the protection box 10. The output end of the motor 502 is fixedly connected to the threaded rod 503. The motor 502 is electrically connected to the controller 13.

[0026] Before the liquid spraying mechanism 30 is used, the spraying assembly 40 needs to be flipped forward by 90 degrees through the retracting and extending mechanism 50 first, so that the two liquid outlet boxes 406 are located on the upper and lower sides of the corresponding trays; during use, the controller 13 starts the motor 502 through an external power supply. The output end of the motor 502 drives the threaded rod 503 to rotate, thereby driving the moving frame 504 to move to the right, thereby driving the connecting rod 505 and multiple groups of spraying assemblies 40 to move in the same direction. While the connecting rod 505 moves to the left, it drives the second gear 506 to roll along the surface of the second toothed plate 507, so that the connecting rod 505 rotates forward by 90 degrees, driving multiple groups of spraying assemblies 40 to flip forward by the same angle, and flipping the spraying assemblies 40 to the outer left end of the tray. At this time, the liquid spraying mechanism 30 is turned on through the controller 13, and the liquid spraying mechanism 30 sprays the tenderizing liquid through the two liquid outlet boxes 406 of the spraying assembly 40. The tenderizing liquid is sprayed on the upper and lower surfaces of the tray. The tenderizing liquid sprayed from the upper liquid outlet box 406 is directly sprayed on the surface of the squid, while the tenderizing liquid sprayed from the lower liquid outlet box 406 will be sprayed on the lower surface of the squid through the holes on the surface of the tray, achieving the effect of spraying the tenderizing liquid on a larger area of the squid. At the same time, the spraying assembly 40 sprays the tenderizing liquid on each squid on the tray as the moving frame 504 moves; achieving the effect of spraying the tenderizing liquid on the squid on the surface of the tray in a large range. Similarly, when the moving frame 504 moves to the left, the second gear 506 gradually approaches the second toothed plate 507 until the second gear 506 meshes with the second toothed plate 507 again. Thus, the second gear 506 rolling along the surface of the second toothed plate 507 will drive the connecting rod 505 to rotate to the right, so that the spraying assembly 40 rotates back to its original position, without preventing the free removal of the tray rack 12.

[0027] Furthermore, a positioning block 510 is fixedly connected above the connecting rod 505. A sliding groove is opened on the left side of the positioning block 510. A positioning plug 511 adapted to the sliding groove is slidably connected inside the sliding groove. The right side of the positioning plug 511 is fixedly connected with a support spring 512. The right side of the support spring 512 is fixedly connected with the inner side of the sliding groove. A downward moving rod 513 passing through the surface of the positioning block 510 is slidably connected to the top of the sliding groove. The bottom of the downward moving rod 513 is hinged with a connecting rod 514. The left end of the connecting rod 514 is hinged with the positioning plug 511 through a hinge; a back plate 515 is fixedly connected to the bottom of the upper cross plate. A fixing groove adapted to the positioning plug 511 is opened on the front surface of the back plate 515; a trigger plate 509 is fixedly connected to the rear side inside the protection box 10. The left surface of the trigger plate 509 is in a "\\" shape.

[0028] After the connecting rod 505 is flipped forward by 90 degrees, the positioning plug 511 will be flipped to face the back plate 515. As the moving frame 504 moves to the right, the top surface of the downward moving rod 513 will contact the left surface of the trigger plate 509. The contact force causes the downward moving rod 513 to move downward, thereby driving the positioning plug 511 to move outward through the connecting rod 514 and insert into the fixing groove on the surface of the back plate 515, so as to achieve the effect of positioning the connecting rod 505 after rotation. And during the process of the connecting rod 514 contacting the downward moving rod 513, the angle of the connecting rod 505 can be kept fixed; when the connecting rod 514 does not contact the downward moving rod 513, the supporting spring 512 rebounds to drive the positioning plug 511 to disengage from the fixing groove, and drives the downward moving rod 513 to move upward through the connecting rod 514, releasing the angle restriction on the connecting rod 505.

[0029] Further, a first gear 404 is fixedly connected to the outer side of the rotating rod 402; a set of fixed frames 408 are fixedly connected to the right side inside the protection box 10, and a set of first toothed plates 409 arranged in a staggered manner are respectively fixedly connected to the upper and lower sides inside the fixed frame 408.

[0030] After the connecting rod 505 drives the spraying assembly 40 to rotate forward by 90 degrees, the first gear 404 and the fixed frame 408 are in the same cross-section position. And when the spraying assembly 40 moves to the right with the moving frame 504, the first gear 404 will enter the vacant area inside the fixed frame 408. And the first gear 404 will first mesh with the upper first toothed plate 409, and as the moving frame 504 continues to move, it will drive the first gear 404 to roll along the surface of the first toothed plate 409, causing the turning plate 405 to rotate counterclockwise with the position of the rotating rod 402 as the center, so that the two liquid outlet boxes 406 rotate in the same direction; when the first gear 404 meshes with the lower first toothed plate 409 and rolls along the surface of the lower first toothed plate 409, it will drive the turning plate 405 and the liquid outlet boxes 406 to rotate clockwise; the liquid outlet boxes 406 spray out liquid while rotating, so as to achieve the state that the liquid outlet boxes 406 spray out liquid in an arc path during the moving process. And because there is a set of first toothed plates 409 on the upper and lower sides of the fixed frame 408 respectively, the liquid outlet boxes 406 will perform arc-shaped rotations reciprocally during the movement. During the swinging process of the upper and lower two liquid outlet boxes 406 spraying liquid in an arc path, they can spray water on the upper and lower surfaces of the squid at different angles. Compared with the nozzles moving in parallel, it can avoid the situation of insufficient or uneven liquid spraying in the edge area caused by spraying the tenderizing liquid in a single direction. Especially for squids with irregular shapes, the arc-shaped swinging spraying of the tenderizing liquid can better fit the contour of the squid, so that the entire surface can be evenly sprayed with the liquid.

[0031] The working principle of the present invention is as follows: The temperature control mechanism 20 is turned on through the controller 13. The temperature control mechanism 20 first monitors the temperature inside the protection box 10 through the temperature sensor 207. Then, after the controller 13 receives the signal that the temperature exceeds the range, it will send a start command to the semiconductor refrigeration sheet 205. The semiconductor refrigeration sheet 205 starts to work, refrigerates and cools the coolant in the liquid cooling box 201, so that the coolant maintains a relatively low temperature. At the same time, the controller 13 also sends a start command to the first pump 202. The first pump 202 starts to operate. Its input end extracts the low-temperature coolant from the liquid cooling box 201 through a pipeline. The first pump 202 transports the extracted coolant to the liquid cooling pipe 203 through the output end. The coolant 203 circulates in the liquid cooling pipe, exchanges heat with the inside of the protection box 10, absorbs the heat inside the protection box 10, thereby reducing the temperature inside the protection box 10. The coolant after heat exchange flows back to the liquid cooling box 201 from the other end of the liquid cooling pipe 203 and is refrigerated and cooled by the semiconductor refrigeration sheet 205 again, forming a cyclic refrigeration process; when the temperature sensor 207 monitors that the temperature inside the protection box 10 drops to the temperature value set by the controller 13, after the controller 13 receives the signal that the temperature has reached the set value, it will send a stop command to the semiconductor refrigeration sheet 205 and the first pump 202. The semiconductor refrigeration sheet 205 stops refrigerating, the first pump 202 stops operating, and the coolant stops circulating. Thus, the effect of controlling the temperature inside the protection box 10 is achieved.
