Description

Technical Field

[0001] The invention relates to the technical field of freezing equipment, in particular to a freezing device for producing crab sticks. Background Art

[0002] In the existing field of crab stick processing and freezing technology, traditional freezing devices generally use a multi-layer partition-type low-temperature storage structure for batch freezing. Although this type of equipment can achieve the function of quick freezing of products, it has significant defects in the material storage and retrieval process, which are specifically manifested as follows:

[0003] Traditional equipment uses a vertical stacking freezer design, and the distance between the crab stick trays on each layer is reduced. Operators need to squat into the -25℃ low temperature environment to retrieve materials. Actual production data shows that a single retrieval action takes 25 to 40 seconds, and the lower tray needs to be completely removed from the upper tray, resulting in more than 30% ineffective handling operations.

[0004] At the same time, the opening size of the freezer is generally maintained in the range of 40cm×60cm, and the depth of the operating channel exceeds 80cm, causing the operator's forearm to be completely exposed to the low temperature environment, posing certain safety hazards.

[0005] Finally, most of the existing equipment is not equipped with a mechanical material removal mechanism, and relies on manual use of hook-shaped tools to separate materials. When there is a large amount of ice crystals attached to the surface of crab sticks, the manual sorting error rate will increase. Frequent opening and closing of the warehouse door will cause the temperature in the warehouse to fluctuate by more than ±3°C, which will directly affect the stability of the product's frozen crystal structure.

[0006] These problems lead to the freezing process taking up most of the time in the actual production process, and the material retrieval process directly causes a certain product damage rate. Therefore, the development of a crab stick freezing device with efficient storage and retrieval functions has become a technical bottleneck that the industry needs to solve urgently.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0043] An embodiment of the present invention provides a freezing device for crab stick production, including a quick-freezing chamber 2. A base 1 is arranged below the quick-freezing chamber 2. A pair of support side plates 101 are fixedly installed between the bottom of the quick-freezing chamber 2 and the base 1. The quick-freezing chamber 2 has an annular structure, and further includes;

[0044] Carrying component, the carrying component includes a turntable 4 rotatably installed at the bottom inside the quick-freezing chamber 2, and a plurality of partition plates 401 are fixedly installed on the surface of the turntable 4.

The placing component 5 includes a box body seat 513. The box body seat 513 is detachably and fixedly installed on the turntable 4. An activity box cover 501 is rotatably installed on the box body seat 513 through a movable shaft. The side surface of each activity box cover 501 is in a right trapezoid structure. The inclined ends of the activity box covers 501 are connected with activity plates 502 through hinges. A plurality of placing openings are arranged at equal distances on the activity plates 502. A placing wire mesh box 505 is fixed in each placing opening. A plurality of installation openings 8 are arranged on one side of each placing wire mesh box 505. A memory metal wire strip 801 is fixedly installed on one side of each installation opening 8. The memory metal wire strip 801 is in an arc shape after being heated; through the above structure, the plurality of placing wire mesh boxes 505 provided can store the crab sticks separately. At the same time, the inclined surface setting of the activity box cover 501 makes the opening distribution of the placing wire mesh box 505 more three-dimensional, so as to facilitate the feeding operation; on the other hand, the memory metal wire strip 801 is in an arc shape after being heated (see Figure 14 ), which can automatically expand the gap of the placing wire mesh box 505 to reduce the adhesion between the crab sticks and the placing wire mesh box 505, facilitate discharging, and at the same time, can avoid the appearance damage of the crab sticks caused by adhesion during the discharging process; at the same time, the placing component 5 between each partition plate 401 rotates with the turntable 4 and passes through the feeding port 201 and the discharging port 202 in turn, realizing continuous feeding and discharging, without the need for manual operation in a low-temperature environment, and significantly shortening the storage and retrieval time.

[0045] Heat dissipation and utilization component, the heat dissipation and utilization component is arranged on the base 1; the heat dissipation and utilization component utilizes the heat generated during the refrigeration process of the subsequent refrigeration compressor component 3 and guides it to the placing component 5 through a pipeline for thawing the crab sticks after quick-freezing.

At the same time, the plurality of partition plates 401 arranged can evenly divide the internal space of the quick-freezing chamber 2, so as to effectively reduce the temperature fluctuation inside the quick-freezing chamber 2 during the loading and unloading process, thereby ensuring the freezing quality of the crab sticks.

[0047] Further, magnetic attraction sheets 509 are fixedly installed at one end of each movable plate 502 and the movable box cover 501, and the corresponding two magnetic attraction sheets 509 form a magnetic adsorption fit. A pull bar 504 is fixedly installed at the end of each movable plate 502. The provided magnetic attraction sheets 509 facilitate the adsorption and fixation of the movable plate 502 and the movable box cover 501. Meanwhile, after the crab sticks are thawed, the movable plate 502 can be pulled through the pull bar 504, so that the movable plate 502 is in the state as shown in Figure 12 . At this time, the opening of the placing cage 505 inclines downward, thereby facilitating the rapid blanking of the crab sticks.

[0048] Further, each placing cage 505 is inclined with respect to the turntable 4.

[0049] As a further solution of the present invention, as shown in Figure 9 - Figure 13 , a water receiving box 508 is movably inserted at the bottom of each box body base 513. Oval slots 506 are formed on both sides of each box body base 513, and oval slots 507 are formed on both sides of each movable box cover 501.

[0050] Further, a support platform column 511 is fixedly installed at the inner bottom of each box body base 513, and a support spring 512 is fixedly installed at the top of the support platform column 511. The support spring 512 is used to abut against the movable box cover 501.

[0051] Further, a corrugated film 510 is fixedly connected between the end of the movable box cover 501 and the side of the box body base 513 away from the movable plate 502. The provided corrugated film 510 can improve the sealing performance between the movable box cover 501 and the box body base 513, and at the same time does not affect the relative movement between the movable box cover 501 and the box body base 513.

[0052] Further, a refrigeration compressor assembly 3 is fixedly installed on the base 1, and a plurality of heat exchange medium channel pipes 301 are fixedly arranged on the refrigeration compressor assembly 3. The plurality of heat exchange medium channel pipes 301 extend into the quick-freezing chamber 2. The provided refrigeration compressor assembly 3 and the plurality of heat exchange medium channel pipes 301 can make the quick-freezing chamber 2 in a low-temperature state.

[0053] Further, the heat dissipation utilization assembly includes a heat discharge pipe 6. The heat discharge pipe 6 is fixedly installed at the heat dissipation end of the refrigeration compressor assembly 3, and the end of the heat discharge pipe 6 is fixedly communicated with a cavity box 601. An auxiliary fan 603 is fixedly installed in the middle of the cavity box 601. A pair of extension branch pipes 602 are fixedly communicated with the bottom of the cavity box 601. A conical pipe 503 is fixedly communicated with the top of each movable box cover 501. The end of the extension branch pipe 602 is in a bevel shape.

[0054] Through the above structure, when the box body base 513 moves to directly below the cavity box 601, as shown in Figure 1 andFigure 4 As shown, at this time, the extended branch pipe 602 will collide with the tapered pipe 503 and form a docking effect; at this time, the movable box cover 501 is squeezed and turned downward along the connection, and at this time, the oblong notch 1 506 and the oblong notch 2 507 are staggered with each other, so that the movable box cover 501 and the box body seat 513 form a relatively closed space, and at this time, the hot air drawn out by the auxiliary fan 603 enters the interior of the movable box cover 501 through the heat exhaust pipe 6, the extended branch pipe 602 and the tapered pipe 503, and uses the hot air to exchange heat with the net box 505, so as to realize the thawing of the crab sticks;

[0055] When the movable box cover 501 enters the quick-freezing chamber 2 without being squeezed, under the action of the supporting spring 512, the oblong notch 1 506 and the oblong notch 2 507 are in a positively aligned state. At this time, the cold air in the quick-freezing chamber 2 can directly enter the interior of the placement component 5, which is beneficial to improve the freezing effect of the crab sticks.

[0056] As a further solution of the present invention, an annular sink groove 402 is provided at the bottom of the turntable 4 , and a driven conical gear ring 704 is fixedly installed inside the annular sink groove 402 . A through opening 703 is provided at the bottom of the quick freezing chamber 2 .

[0057] Furthermore, an installation box 7 is fixedly installed at a position near the through opening 703 at the bottom of the quick-freezing chamber 2, and a driving motor 701 is fixedly installed in the installation box 7. A driving conical tooth 702 is fixedly installed on the output shaft of the driving motor 701, and the driving conical tooth 702 and the driven conical tooth ring 704 are meshed with each other; through the above structure, when the driving motor 701 is running, the drive of the driving conical tooth 702 and the driven conical tooth ring 704 can drive the turntable 4 to rotate, so as to realize the rapid loading and unloading of crab sticks.

[0058] The specific working method is as follows: when in use, the crab sticks to be frozen are placed on the empty movable plate 502 in turn, and the crab sticks are stored separately by using the multiple placement boxes 505 to prevent adhesion during freezing. After the crab sticks are placed, the driving motor 701 drives the turntable 4 to rotate through the transmission effect of the driving conical teeth 702 and the driven conical gear ring 704, and the crab sticks are rotated into the quick-freezing chamber 2 for quick freezing. The partitions 401 distributed in a circular array on the turntable 4 divide the quick-freezing chamber 2 into a plurality of independent freezing areas, and the placement components 5 between each partition 401 rotate with the turntable 4, and pass through the feed port 201 and the discharge port 202 in turn, so as to realize continuous feeding and discharging, without the need for manual operation in the low-temperature environment, and significantly shortening the storage and access time. At the same time, Figure 1 and Figure 4As shown, when the partition 401 is at the position of the feed port 201 and the discharge port 202, the quick-freezing chamber 2 can be sealed, and at the same time, the multiple partitions 401 can evenly divide the internal space of the quick-freezing chamber 2, so that during the loading and unloading process, the temperature fluctuation inside the quick-freezing chamber 2 is effectively reduced, thereby ensuring the freezing quality of the crab sticks; and when the movable box cover 501 enters the quick-freezing chamber 2 without being squeezed, under the action of the support spring 512, the oblong notch 1 506 and the oblong notch 2 507 are in a positively aligned state, at this time, the cold air in the quick-freezing chamber 2 can directly enter the interior of the placement component 5, which is beneficial to improve the freezing effect of the crab sticks;

[0059] When it is necessary to take out the material, the rotating disk 4 can be controlled to rotate so that the quick-frozen crab sticks can be rotated out through the discharge port 202. When the box body seat 513 moves to the bottom of the cavity box 601, as shown in FIG. Figure 1 and Figure 4 As shown, at this time, the extended branch pipe 602 will collide with the tapered pipe 503 and form a docking effect; at this time, the movable box cover 501 is squeezed and turned down along the connection. At this time, the oblong notch 1 506 and the oblong notch 2 507 are staggered with each other, so that the movable box cover 501 and the box body seat 513 form a relatively closed space. At this time, the hot air drawn by the auxiliary fan 603 enters the interior of the movable box cover 501 through the heat exhaust pipe 6, the extended branch pipe 602 and the tapered pipe 503, and uses the hot air to exchange heat with the placement net box 505, so as to realize the thawing of the crab sticks; the memory metal mesh strip 801 is in an arc shape after being heated (see Figure 14 ), the gap between the net box 505 can be automatically opened to reduce the adhesion between the crab sticks and the net box 505, making it easier to unload the crab sticks. At the same time, the appearance of the crab sticks can be prevented from being damaged due to adhesion during the unloading process;

[0060] After the crab sticks are thawed, the movable plate 502 can be pulled by the pull bar 504 so that the movable plate 502 can be Figure 12 In the state shown, at this time, the opening of the net box 505 is tilted downward, so as to facilitate the rapid feeding of crab sticks; at the same time, after the movable plate 502 is reset, hot air can continue to be used for drying to prevent moisture residue, thereby effectively avoiding the formation of ice crystals during the freezing process and ensuring the freezing quality of the crab sticks.
