Technical Field

[0001] The present invention relates to the technical field of ultrasonic frozen squid processing, and specifically to a processing device for frozen squid prepared by using ultrasonic technology. Background Art

[0002] After squids are caught, they need to be quickly frozen. However, due to operating conditions, whole-strip freezing or segmented freezing is often used, resulting in uneven ice crystal distribution, serious damage to muscle fibers, increased protein freeze denaturation, and decreased water holding capacity. Therefore, an ice glazing operation is carried out on squids by using ultrasonic technology.

[0021] The present invention provides an apparatus for processing frozen squid using ultrasonic technology through improvement. Compared with the prior art, it has the following improvements and advantages:

[0022] First: By setting the first ultrasonic ice coating machine and the second ultrasonic ice coating machine, the present invention enhances the adhesion between the ice coating and the muscle in the first layer of ice coating, inhibits ice crystal recrystallization, reduces cell damage. The second layer of ice coating inhibits lipid oxidation and protein denaturation through antioxidant action, and at the same time improves the mechanical strength of the ice coating, reducing the cracking of the ice coating caused by temperature fluctuations during frozen storage. The frozen storage quality of squid is improved through the layered ice coating technology, and ultrasonic oscillation is used to eliminate air bubbles in the ice coating liquid, improving the transparency and adhesion of the ice layer;

[0023] Second: By setting the first guide rail, driven by the transmission rope, the moving frame drives the squid to automatically descend and ascend through the round rod, the support sleeve and the placement mechanism, thus facilitating the ice coating work with high automation;

[0024] Third: When the placement mechanism is lifted guided by the second guide rail, the placement mechanism can rotate by itself. At the same time, when the first guide rod moves along the bumpy rail, it drives the placement mechanism to vibrate bumpily, so as to quickly remove the ice coating liquid remaining on the placement mechanism. By setting the convex strips, the squid in the placement mechanism will not easily adhere to the placement mechanism, thus accelerating the draining time of the squid;

[0025] Fourth: When the present invention guides the first guide rod to move downward by setting the second guide rail, the annular tube drives the piston rod to twitch through the connecting frame, and the outside air is twitched into the inside of the piston cylinder through the one-way air inlet valve. When the first guide rod moves upward, the piston rod squeezes the air into the inside of the annular tube through the hose, and the air is ejected by multiple air outlet nozzles to blow the squids in the placing mechanism, further accelerating the draining time of the squids;

[0026] Fifth: By setting the third guide rail, the present invention enables the third guide rail to guide the second guide rod to drive the cover body to move upward, so that the cover body disengages from the multiple placing mechanisms, and the placing mechanisms rotate downward under the influence of their own gravity, causing the squids to fall into the subsequent receiving device, thus facilitating the feeding work.

[0039] The present invention provides an apparatus for processing frozen squid using ultrasonic technology by improvement. The technical solution of the present invention is as follows:

[0040] As Figures 1-8 shown, an apparatus for processing frozen squid using ultrasonic technology includes a pre-freezing room 1. A first ice-coating room 2 is fixedly arranged on the side of the pre-freezing room 1. A first ultrasonic ice-coating machine 3 is fixedly arranged inside the first ice-coating room 2. A quick-freezing room 4 is fixedly arranged on the side of the first ice-coating room 2. A second ice-coating room 5 is fixedly arranged on the side of the quick-freezing room 4. A second ultrasonic ice-coating machine 6 is fixedly arranged inside the second ice-coating room 5. A freezing addition room 7 is fixedly arranged on the side of the second ice-coating room 5. A first guide rail 8 is fixedly installed on the pre-freezing room 1, the first ice-coating room 2, the second ice-coating room 5 and the freezing addition room 7 together. A transmission rope 9 is movably arranged inside the first guide rail 8;

[0041] A plurality of moving frames 10 movably connected to the first guide rail 8 are fixedly installed on the transmission rope 9. A round rod 11 is fixedly installed on each moving frame 10. A support sleeve 12 is movably installed on the outer side of the round rod 11. A plurality of placing mechanisms are hingedly installed on the support sleeve 12;

[0042] The placing mechanism includes a placing piece 13 hingedly installed at the bottom end of the support sleeve 12. A placing shell 14 is fixedly installed on the placing piece 13.

[0043] Specifically, the transmission rope 9 drives the entire squid processing production line to perform transmission work through an externally connected transmission wheel and a driving device. The staff places the squid between the placing piece 13 and the placing shell 14, controls the transmission rope 9 to drive the moving frame 10 to move along the first guide rail 8, and drives the squid to enter the pre-freezing room 1, the first ice glazing room 2, the quick-freezing room 4, the second ice glazing room 5, and the freezing room 7 in sequence through the placing piece 13 and the placing shell 14 to perform ice glazing work on the squid, so as to complete the processing work of frozen squid;

[0044] By setting the first ultrasonic ice glazing machine 3 and the second ultrasonic ice glazing machine 6, the adhesion between the ice glaze and the muscle is enhanced in the first layer of ice glazing, the recrystallization of ice crystals is inhibited, cell damage is reduced, and in the second layer of ice glazing, lipid oxidation and protein denaturation are inhibited through antioxidant action, while the mechanical strength of the ice glaze is improved, and the cracking of the ice glaze caused by temperature fluctuations during frozen storage is reduced. The frozen storage quality of squid is improved through the layered ice glazing technology, and ultrasonic vibration is used to eliminate the bubbles in the ice glazing liquid, improving the transparency and adhesion of the ice layer.

[0045] In this embodiment, as Figures 1-8 shown, a second guide rail 16 is fixedly installed on the pre-freezing room 1, the first ice glazing room 2, the second ice glazing room 5, and the freezing room 7 together. A telescopic mechanism is provided on each support sleeve 12. The telescopic mechanism includes two limit rings 18 fixedly installed on the support sleeve 12. A collar 20 is movably installed between the two limit rings 18. A first guiding rod 19 movably connected to the second guide rail 16 is fixedly installed on the collar 20. The telescopic mechanism further includes a first spring 21 connected to the bottom end of the round rod 11. The end of the first spring 21 is connected to a bottom block 22, and the bottom block 22 is movably installed inside the bottom wall of the support sleeve 12.

[0046] Specifically, by setting the first guide rail 8, driven by the transmission rope 9, the moving frame 10 drives the squid to automatically descend and ascend through the round rod 11, the support sleeve 12, and the placing mechanism, thus facilitating the ice glazing work with high automation;

[0047] Under the guidance of the second guide rail 16, the first guiding rod 19 drives the support sleeve 12 to move downward through the collar 20 and the limit rings 18, and the support sleeve 12 drives the squid to move into the ice glazing liquid with alginate oligosaccharide as the core component in the first ultrasonic ice glazing machine 3 through multiple placing pieces 13 and multiple placing shells 14, and uses the ultrasonic technology of the first ultrasonic ice glazing machine 3 to perform the first layer of ice glazing work, then moves to the quick-freezing room 4 for quick-freezing work, continues to move into the ice glazing liquid with sodium citrate and sodium L-ascorbate as the core component in the second ultrasonic ice glazing machine 6, uses the ultrasonic technology of the second ultrasonic ice glazing machine 6 to perform the second layer of ice glazing work, and then moves into the freezing room 7 for the final ice glaze reinforcement work;

[0048] When the support sleeve 12 moves, the first spring 21 supports the movement of the support sleeve 12 through the bottom block 22 by means of its own elastic force.

[0049] In this embodiment, as Figures 1-8 shown, two bump rails 17 adapted to the telescopic mechanism are fixedly installed on the first guide rail 8. Guide grooves 23 are formed on each round rod 11, and hemispherical blocks 24 adapted to the guide grooves 23 are fixedly installed on the inner walls of each support sleeve 12. A blowing mechanism for accelerating the draining work is provided on each moving frame 10. A plurality of through holes are formed on each placing piece 13 and each placing shell 14. A plurality of convex strips 15 are fixedly installed on the inner wall of each placing shell 14. A cover body 25 is movably installed on the plurality of placing pieces 13 together. A fixing ring 26 is fixedly installed on the cover body 25. The blowing mechanism includes two piston cylinders 30 fixedly installed on the moving frame 10. A one-way intake valve 31 is fixedly installed on each piston cylinder 30. A piston rod 32 adapted to the piston cylinder 30 is movably installed inside each piston cylinder 30. A connecting frame 33 is fixedly installed at the bottom end of each piston rod 32. The blowing mechanism further includes a ring pipe 28 fixedly installed on the two connecting frames 33. Two sliders 27 adapted to the fixing ring 26 are symmetrically fixedly installed on the ring pipe 28. A plurality of air outlet nozzles 29 are fixedly installed on the ring pipe 28. A hose 34 connected to the ring pipe 28 is connected to the piston cylinder 30.

[0050] Specifically, when the second guide rail 16 guides the lifting of the placing mechanism, the support sleeve 12 drives the hemispherical block 24 to move along the inner side of the guide groove 23, so that the support sleeve 12 can drive the placing mechanism to rotate by itself. At the same time, when the first guide rod 19 moves along the bump rail 17, it drives the placing mechanism to vibrate turbulently, so as to quickly remove the ice coat liquid remaining on the placing mechanism. By providing the convex strips 15, the squid in the placing mechanism will not easily adhere to the placing mechanism, thus accelerating the draining time of the squid.

[0051] When the second guide rail 16 guides the first guide rod 19 to move downward, the ring pipe 28 drives the piston rod 32 to be pumped through the connecting frame 33. The outside air is pumped into the inside of the piston cylinder 30 through the one-way intake valve 31. When the first guide rod 19 moves upward, the piston rod 32 squeezes the air into the inside of the ring pipe 28 through the hose 34, and the air is ejected by the plurality of air outlet nozzles 29 to blow the squid in the placing mechanism, further accelerating the draining time of the squid.

[0052] In this embodiment, as Figures 1-8As shown, two fixed shells 35 are symmetrically and fixedly installed on each support sleeve 12. A second spring 36 is connected to the inner wall of each fixed shell 35. The end of the second spring 36 is connected to a latch 37 adapted to the cover body 25. A third guide rail 38 is fixedly installed on the inner wall of the freezing chamber 7. A second guide rod 39 movably connected to the third guide rail 38 is fixedly installed on each annular pipe 28.

[0053] Specifically, by setting the third guide rail 38, the third guide rail 38 guides the second guide rod 39 to drive the cover body 25 to move upward, so that the cover body 25 squeezes the latch 37 into the inside of the fixed shell 35 under the action of an external force, so that the cover body 25 disengages from the plurality of placing mechanisms. Under the support of the elastic force of the second spring 36, the latch 37 moves out of the inside of the fixed shell 35 again to support the cover body 25, so that the placing mechanism rotates downward under the influence of its own gravity, and the squid falls onto the subsequent receiving conveyor belt assembly, thus facilitating the blanking work.

[0054] Working principle: The staff soaks fresh squid in 0.1 - 0.4 ppm ozone water for 8 - 12 minutes to remove surface mucus, microorganisms and impurities, and reduce the initial total colony count to <10² CFU / g. A high-frequency and low-energy ultrasonic machine is used, and the ultrasonic parameters are set to 25 - 45 kHz and the power is 0.5 - 0.7 W / cm² to assist in cleaning the squid, accelerating the detachment of dirt and reducing the amount of chemical cleaning agent used. A low-speed centrifuge is used, and the parameters are set to 240 - 450 r / min for 30 - 45 seconds to remove surface moisture, and the residual liquid volume ≤ 2 g / 100 g. The squid is transferred to a pre-cooling chamber at 0 - 3°C and left to stand for 50 - 80 minutes. The ice-coating liquid made of 0.04% - 0.08% NaCl + 0.5% - 1.0% alginate oligosaccharide + 0.1% sodium polyacrylate is poured into the first ultrasonic ice-coating machine 3, and the parameters are set to 22 - 42 kHz and the power is 200 - 220 W. The component dissolution is accelerated through the cavitation effect to form micron-sized droplets with a particle size of 10 - 52 μm. The ice-coating liquid made of 0.05% - 0.09% sodium citrate + 0.1% - 0.3% L-ascorbic acid sodium + 0.1% - 0.15% rosmarinic acid is poured into the second ultrasonic ice-coating machine 6;

[0055] The staff places the squid between the placement piece 13 and the placement shell 14, controls the drive rope 9 to drive the moving frame 10 to move along the first guide rail 8, and drives the squid to enter the pre-freezing room 1, the first ice-coating room 2, the quick-freezing room 4, the second ice-coating room 5 and the freezing room 7 in sequence through the placement piece 13 and the placement shell 14. Under the guidance of the second guide rail 16, the first guide rod 19 drives the support sleeve 12 to move downward through the collar 20 and the limit ring 18. After the squid is pre-frozen, the support sleeve 12 drives the squid to move into the ice-coating liquid with alginate oligosaccharide as the core component in the first ultrasonic ice-coating machine 3. After the squid is immersed in the ice-coating liquid, the ultrasonic treatment is started for 30 - 60 seconds, and the mechanical effect is used to enhance the penetration of the ice-coating liquid into the muscle fibers, reducing the ice crystal size to <50μm. The first layer of ice-coating work is carried out using the ultrasonic technology of the first ultrasonic ice-coating machine 3. Then the squid is moved to the quick-freezing room 4 at -52 - -58°C. After quick-freezing, a thin ice-coating base layer is formed on the surface of the squid, and the thickness is controlled at 8% - 10% on one side. Then it is continuously moved into the ice-coating liquid with sodium citrate and sodium L-ascorbate as the core components in the second ultrasonic ice-coating machine 6. The parameters are set at 18 - 36 kHz and the power is 200 - 220 W. The ultrasonic treatment is started for 30 - 60 seconds, and the second layer of ice-coating work is carried out using the ultrasonic technology of the second ultrasonic ice-coating machine 6. Then it is moved into the freezing room 7 for the final ice-coating reinforcement work to carry out the ice-coating work on the squid and complete the processing work of frozen squid;

[0056] When the squid is removed from the first ultrasonic ice-coating machine 3 and the second ultrasonic ice-coating machine 6, when the second guide rail 16 is set to guide the lifting of the placement mechanism, the support sleeve 12 drives the hemispherical block 24 to move along the inner side of the guide groove 23, enabling the support sleeve 12 to drive the placement mechanism to rotate by itself. At the same time, when the first guide rod 19 moves along the bumpy rail 17, it drives the placement mechanism to vibrate bumpily, so as to quickly remove the ice-coating liquid remaining on the placement mechanism. By setting the convex strip 15, the squid in the placement mechanism will not easily stick to the placement mechanism, thus accelerating the draining time of the squid;

[0057] When the second guide rail 16 is set to guide the first guide rod 19 to move downward, the annular tube 28 drives the piston rod 32 to twitch through the connecting frame 33, and the outside air is pumped into the inside of the piston cylinder 30 through the one-way air inlet valve 31. When the first guide rod 19 moves upward, the piston rod 32 squeezes the air into the inside of the annular tube 28 through the hose 34, and it is sprayed out by a plurality of air outlet nozzles 29 to blow the squid in the placement mechanism, further accelerating the draining time of the squid;

[0058] By setting the third guide rail 38, the third guide rail 38 guides the second guide rod 39 to drive the cover body 25 to move upward, so that the cover body 25 squeezes the clamping block 37 into the inner side of the fixed shell 35 under the action of an external force, thereby enabling the cover body 25 to disengage from the plurality of placing mechanisms. Under the support of the elastic force of the second spring 36, the clamping block 37 moves out of the inner side of the fixed shell 35 again to support the cover body 25, causing the placing mechanism to rotate downward under the influence of its own gravity, so that the squid falls onto the subsequent receiving conveyor belt assembly for blanking work;

[0059] Use infrared imaging technology to monitor the cracking rate of the ice coat, set the threshold <5%, and detect the water holding capacity by the weighing method. After 6 months of frozen storage, >62%. Regularly spot-check the antioxidant performance and microbial indicators of the ice coat. The total number of colonies <10³CFU / . After coating the ice coat, use a polyethylene self-sealing bag for packaging to reduce oxygen penetration and dry weight loss. The comprehensive dry weight loss rate <3%. The frozen storage temperature is stable at -15°C ± 1°C. Supplement the ice coat coating once every 60 days, and the shelf life is extended to 12 months.
