Description

Technical Field

[0001] The invention relates to the technical field of fluid heaters, and in particular to energy-saving thawing equipment and technology. Background Art

[0002] In the food processing industry, thawing is one of the key steps in the handling of many frozen foods. For products like duck feet, which have irregular shapes and are usually frozen in large pieces, traditional thawing methods such as air thawing, water bath thawing or microwave thawing have certain limitations, especially when it comes to larger-sized products. Traditional thawing methods may cause serious internal and external temperature difference problems.

[0003] Specifically, in the existing thawing process of large pieces of duck feet ingredients, due to the limitation of heat transfer, the surface of the block ingredients will absorb heat faster than the center, causing the surface temperature to rise rapidly while the inside is still in a low temperature or even frozen state. This phenomenon not only prolongs the time required for the overall thawing, but may also cause the problem of excessive heating of the surface, affecting the texture and taste of the product. In addition, long-term exposure to non-freezing conditions may also increase the risk of microbial reproduction, thereby threatening food safety. Summary of the invention

[0004] In view of this, the present invention provides an energy-saving thawing device and process, which can solve the problem that in the existing thawing process of large pieces of duck feet ingredients, the surface of the block ingredients absorbs heat faster than the center, resulting in the center of the block ingredients taking a longer time to thaw, which not only prolongs the time required for the overall thawing, thereby possibly causing the risk of microbial reproduction, but also easily causes the surface of the block ingredients to be overheated.

[0030] See Figure 2 and Figure 3 As shown in the figure, the lifting mechanism includes a lead screw 501 and a servo motor 502; two lead screws 501 are rotatably arranged between the thawing pool 1 and the top frame 2, and the storage frame 4 is threadedly connected with the lead screw 501; two servo motors 502 are installed on the top frame 2, the output shafts of the two servo motors 502 are respectively connected with the two lead screws 501, the servo motor 502 is electrically connected with the controller 7, and the servo motor 502 is used to drive the lead screw 501 to rotate so as to drive the storage frame 4 to lift and lower.

[0031] See Figure 6 and Figure 7As shown in the figure, the water delivery mechanism includes a water pump 1301, a water outlet pipe 1302, a hollow frame 1303, a circular frame 1304, a first connecting pipe 1305, a second connecting pipe 1306 and a copper pipe 1307; a water pump 1301 is installed on the lower right side of the thawing pool 1, and the water pump 1301 is electrically connected to the controller 7; a water outlet pipe 1302 is connected between the water inlet of the water pump 1301 and the thawing pool 1; a hollow frame 1303 is installed on the rear right side of the thawing pool 1; a circular frame 1304 is installed on the lower right part of the rear side of the hollow frame 1303; both ends of the first connecting pipe 1305 are respectively connected to the water outlet of the water pump 1301 and the circular frame 1304; both ends of the second connecting pipe 1306 are respectively connected to the hollow frame 1303 and the circular frame 1304; a copper pipe 1307 is connected at intervals between the hollow frame 1303 and the water storage frame 10.

[0032] When it is necessary to freeze and store duck claws, lift the lid 9 of the storage bucket 8, then put an appropriate amount of duck claws into the storage bucket 8, and then cover the lid 9 back on the storage bucket 8 to freeze and store the duck claws in the storage bucket 8; later, when it is necessary to thaw the duck claws in the storage bucket 8, stack the storage buckets 8 on the supporting frame 6, then the workers stand on the supporting frame 6 together, and then control the servo motor 502 to drive the lead screw 501 to rotate through the controller 7, so that the lead screw 501 drives the placing frame 4, the supporting frame 6, the storage bucket 8 and the workers to rise, so that the placing frame 4 rises from the thawing pool 1, and then manually transfer the storage bucket 8 on the supporting frame 6 to the placing frame 4 for stacking, and another worker adds an appropriate amount of clean water into the thawing pool 1. After all the storage buckets 8 are stacked in the placing frame 4, control the servo motor 502 to drive the lead screw 501 to reverse and reset through the controller 7, so that the lead screw 501 drives the placing frame 4, the supporting frame 6 and the workers to descend, so that the placing frame 4 descends back into the thawing pool 1 again, and then the clean water in the thawing pool 1 completely submerges the storage bucket 8, so that the clean water thaws the duck claws in the storage bucket 8 by means of heat conduction. Then, control the water pump 1301 and the heater 11 to start through the controller 7, so that the water pump 1301 pumps the clean water in the thawing pool 1 into the water outlet pipe 1302, the first connecting pipe 1305, the circular frame 1304, the second connecting pipe 1306 and the hollow frame 1303, so that the clean water in the hollow frame 1303 flows into the water storage frame 10 through the copper pipe 1307, and then the heater 11 heats the clean water in the water storage frame 10. The heated clean water will flow back to the thawing pool 1 through the water inlet pipe 12, so as to increase the temperature of the clean water in the thawing pool 1 and accelerate the thawing speed of the duck claws. By setting the main pipe 801 and the branch pipe 802, when the clean water in the thawing pool 1 flows through the main pipe 801 and the branch pipe 802 through the through hole 901 of the lid 9, it can thaw the duck claws in the central area close to the storage bucket 8. In this way, the inside and outside of the duck claws can be thawed simultaneously, thus improving the thawing efficiency of the duck claws.

[0033] After all the duck claws in the storage bucket 8 are completely thawed, the controller 7 is used to control the water pump 1301 and the heater 11 to turn off. Then the worker stands on the supporting bracket 6 again. Next, the controller 7 is used to control the servo motor 502 to drive the lead screw 501 to rotate, so that the lead screw 501 drives the storage frame 4, the supporting bracket 6 and the worker to rise, so that the storage frame 4 rises from the thawing pool 1. Then the worker manually transfers the storage bucket 8 in the storage frame 4 to the supporting bracket 6 for stacking, and another worker drains the clear water in the thawing pool 1. After all the storage buckets 8 are stacked in the storage frame 4, the controller 7 is used to control the servo motor 502 to drive the lead screw 501 to reverse and reset, so that the lead screw 501 drives the storage frame 4, the supporting bracket 6, the storage bucket 8 and the worker to descend, so that the storage frame 4 descends back into the thawing pool 1 again. Then the worker can carry away the storage bucket 8 on the supporting bracket 6; when the duck claws in the storage bucket 8 are needed, the lid 9 of the storage bucket 8 is lifted again, and then the thawed duck claws in the storage bucket 8 are taken out. After that, the lid 9 is covered back on the storage bucket 8 again.

[0034] See Figure 8 and Figure 9 As shown, it further includes an energy-saving mechanism. The energy-saving mechanism includes a heat-conducting sheet 14, a ventilation hood 15 and a fan 16; heat-conducting sheets 14 are arranged at intervals outside the copper pipe 1307; a ventilation hood 15 is installed between the hollow frame 1303 and the water storage frame 10. A ventilation opening is provided at the top of the ventilation hood 15 for exhausting the air inside the ventilation hood 15. The heat-conducting sheet 14 is located inside the ventilation hood 15; fans 16 are installed at intervals on the lower rear side of the ventilation hood 15. The fans 16 are used to introduce air into the ventilation hood 15, so as to exchange heat for the clear water in the copper pipe 1307 through the heat-conducting sheet 14.

[0035] See Figure 9 and Figure 10 As shown, it further includes a driving mechanism. The driving mechanism includes a first gear 17, a rotating rod 18, an impeller 19 and a second gear 20; a first gear 17 is connected to the rotating shaft of the fan 16; a rotating rod 18 is rotatably arranged between the water storage frame 10 and the circular frame 1304; the right end of the rotating rod 18 is connected with an impeller 19. The impeller 19 is located inside the circular frame 1304 and can drive the impeller 19 to rotate when the clear water enters the circular frame 1304; second gears 20 are connected to the rotating rod 18 at intervals. The second gear 20 meshes with the first gear 17. The rotation of the impeller 19 can drive the rotating rod 18 and the second gear 20 to rotate, thereby driving the rotating shaft of the first gear 17 and the fan 16 to rotate, and further driving the blades of the fan 16 to rotate.

[0036] When clear water is pumped into the circular frame 1304, the clear water will drive the impeller 19 to rotate, causing the impeller 19 to drive the second gear 20 and the rotating rod 18 to rotate, thereby driving the first gear 17 and the rotating shaft of the fan 16 to rotate, and further driving the blades of the fan 16 to rotate, so that the fan 16 can introduce the outside air into the ventilation hood 15. When the outside air enters the ventilation hood 15, the outside air can conduct heat to the clear water flowing in the copper pipe 1307 through the heat-conducting fins 14, thereby absorbing heat from the clear water flowing in the copper pipe 1307, so as to increase the temperature of the clear water in the copper pipe 1307. In this way, when the clear water in the copper pipe 1307 flows into the water storage frame 10 for heating, since the initial temperature of the clear water has been increased, the total heat that the heater 11 needs to provide can be reduced, thereby reducing the overall energy consumption.

[0037] See Figure 9 As shown, it also includes a drain pipe 21; the lower left and right sides of the rear of the ventilation hood 15 are symmetrically connected with the drain pipe 21, and the drain pipe 21 is used to discharge the accumulated liquid in the ventilation hood 15.

[0038] When clear water is flowing in the copper pipe 1307, affected by the temperature of the clear water, the temperature on the outer surface of the copper pipe 1307 will decrease. At this time, the water vapor in the air will condense into liquid water droplets when it comes into contact with the surface of the copper pipe 1307, and when the liquid water droplets converge to a certain weight, they will fall downward under the influence of gravity to the bottom of the ventilation hood 15 to form accumulated liquid. When accumulated liquid forms at the bottom of the ventilation hood 15, the drain pipe 21 can be used to discharge the accumulated liquid at the bottom of the ventilation hood 15 to prevent the accumulated liquid from remaining at the bottom of the ventilation hood 15.

[0039] See Figure 11 As shown, it also includes an electric stirrer 22; two electric stirrers 22 are provided at the top of the inner part of the storage frame 4 and the bottom of the inner part of the thawing pool 1 respectively. The electric stirrer 22 is electrically connected to the controller 7, and the electric stirrer 22 is used to stir the clear water in the thawing pool 1.

[0040] By setting the electric stirrer 22, when the duck claws in the storage bucket 8 are thawed in the thawing pool 1, the controller 7 can be used to control the electric stirrer 22 to start, so that the electric stirrer 22 stirs the clear water in the thawing pool 1, thereby improving the fluidity of the clear water, and further improving the efficiency and uniformity of the thawing process.

[0041] See Figures 1-7As shown in the figure, the present invention also provides a process for an energy-saving thawing device, which includes the following steps: First, store the duck claws in the storage barrel 8 and perform frozen storage; when thawing later, take out the storage barrel 8 from the storage barrel 8 and stack it on the support bracket 6; then, control the lifting frame 4 and the support bracket 6 to rise through the lifting mechanism; then, transfer the storage barrel 8 on the support bracket 6 to the lifting frame 4, and add clean water to the thawing pool 1; subsequently, control the lifting frame 4 and the support bracket 6 to descend through the lifting mechanism, so that the storage barrel 8 is immersed in the clean water in the thawing pool 1, thereby thawing the duck claws in the storage barrel 8; then, control the water pump 1301 and the heater 11 to be turned on by the controller 7, so that the water pump 1301 pumps the clean water in the thawing pool 1 into the water storage frame 10 for heating, and then the heated clean water in the water storage frame 10 is sent back to the thawing pool 1 through the water inlet pipe 12; after that, when all the duck claws in the storage barrel 8 are completely thawed, control the water pump 1301 and the heater 11 to be turned off by the controller 7; then, control the lifting frame 4 and the support bracket 6 to rise again through the lifting mechanism, so that the storage barrel 8 leaves the clean water in the thawing pool 1; then, manually transfer the storage barrel 8 in the lifting frame 4 to the support bracket 6 again and drain the clean water in the thawing pool 1; then, control the lifting frame 4 and the support bracket 6 to descend again through the lifting mechanism; after that, manually remove the storage barrel 8 on the support bracket 6; finally, take out the duck claws from the storage barrel 8.
