Description

Technical Field

[0001] This invention relates to the field of freezing equipment technology, and more specifically, to a microcrystalline freezing system and freezing method for beef preservation. Background Technology

[0002] Beef, as one of the most commonly consumed meats, is widely loved. It is rich in protein, fat, B vitamins, niacin, calcium, phosphorus, iron, cholesterol, and other components, and is believed to have benefits such as nourishing the stomach and promoting recovery, as well as aiding weight loss. With the development of the catering industry, the demand for fresh meat products has increased significantly. To ensure the quality and supply of meat products, rapid freezing technology is a suitable and effective solution. However, most rapid freezing currently uses air freezing, dry ice freezing, and liquid nitrogen freezing. Rapid freezing machinery mostly uses liquid nitrogen freezing, but liquid nitrogen is highly volatile, difficult to recycle, and expensive, significantly increasing storage and usage costs when applied to food.

[0003] In the field of microcrystal freezing technology, most methods utilize high-speed liquid freezing with alcohol as the medium, which can reduce the size of food ice crystals. Currently, the main method involves placing beef directly onto the equipment for freezing.

[0004] Currently, there is a lack of equipment that can gently squeeze out some of the moisture from the beef, flatten it, and then use an alcohol insulator to keep it warm during the freezing process, thus reducing temperature loss. Summary of the Invention

The first semi-circular tail groove and the second semi-circular tail groove are respectively matched with the main circular block.

[0013] A microcrystal freezing method for preserving beef includes the following steps:

[0014] S1: Pour an appropriate amount of alcohol into the placement tank, operate the heat preservation device to cool the placement tank to about -℃. At this time, the alcohol is similar to the boiling state of water.

[0015] S2: In the initial state, the round block is in the placement slot. The beef is placed on the carrier plate, and the motor is controlled to rotate, so that the placement component and the rack can move.

[0016] S3: When the round block moves along the arc groove on one side, the pressure plate and the lower push rod move toward the direction of the carrying plate, so that the lower push rod is inserted into the round hole and the pressure plate contacts the beef;

[0017] S4: When the round block moves along the extrusion groove, the spring is slightly compressed, and the upper end of the lower push rod is flush with the upper side of the carrier plate, so as to achieve beef leveling and moisture squeezing.

[0018] S5: When the circular block moves along the arc groove on the other side, the pressure plate and the lower push rod move away from the load plate;

[0019] S6: When the round block moves along the translation groove, it enters the area composed of the upper arc cover and the lower box body through the L groove. The arc-shaped heat preservation plate closes the L groove, the heat preservation plate leaves the placement groove, the carrying plate moves above the placement groove, and the cold air achieves freezing and dormancy of the beef through the round hole.

[0020] S7: After the freezing period ends, control the motor to rotate in the opposite direction, so that the round block moves to the initial position and the frozen beef is taken out.

[0021] As a further limitation of this technical solution, in the initial state, the round block is located in the placement slot, which facilitates the placement of beef. By setting the arc groove, the relative movement of the pressure plate and the lower push rod can be easily realized, thereby squeezing the beef, leveling the beef, and squeezing out some moisture. By setting the round hole, it is convenient to achieve squeezing while facilitating subsequent freezing.

[0022] As a further limitation of this technical solution, by employing gear and rack meshing and gear meshing, the synchronous movement of the arc-shaped insulation plate and the insulation plate is achieved. In the initial state, the arc-shaped insulation plate is away from the L-groove, and the insulation plate completely closes the placement groove, achieving alcohol insulation in the placement groove. After the gear and rack mesh, the carrying plate enters the upper arc cover, the arc-shaped insulation plate swings to block the L-groove, and the insulation plate moves away from the placement groove, achieving cold air sealing in the area composed of the upper arc cover and the lower box, reducing temperature loss.

[0023] As a further limitation of this technical solution, by setting the retaining spring, the position of the arc-shaped insulation board and the insulation board can be maintained, which facilitates heat preservation and reduces temperature loss.

[0024] Compared with the prior art, the advantages and positive effects of the present invention are as follows: The device is equipped with a placement slot, an arc slot, a pressing slot, an arc slot and a translation slot connected in sequence. The round block is placed in the placement slot and the pressure plate is away from the carrying plate, which facilitates the placement of beef. The arc slot facilitates the relative movement of the pressure plate and the lower push rod, thereby squeezing the beef, leveling the beef and squeezing out some water. The round hole facilitates the subsequent freezing while squeezing.

[0025] The insulation components of this device employ gear and rack meshing, as well as gear meshing, to achieve synchronous movement of the arc-shaped insulation plate and the insulation plate itself. Initially, the arc-shaped insulation plate is away from the L-groove, completely sealing the placement groove and maintaining the temperature of the alcohol within. After gear and rack meshing, the loading plate enters the upper arc cover, and the arc-shaped insulation plate swings to block the L-groove, moving away from the placement groove. This seals the cold air within the area formed by the upper arc cover and the lower chamber, reducing temperature loss. When the main circular block enters the first and second semi-circular tail grooves, it perfectly fits them and matches the auxiliary groove. The arc-shaped insulation plate, main circular block, upper arc cover, auxiliary arc block, and lower chamber form a relatively sealed area, further reducing temperature loss.

When the round block 38 moves along the other side of the arc groove 14, the pressure plate 32 and the lower push rod 37 move away from the carrier plate 33, so that the carrier plate 33 moves the beef to the top of the placement groove 49, so as to achieve freezing.

[0055] Example 2: This example is a further elaboration based on Example 1. The upper arc cover 41 is rotatably connected to the heat insulation component 5. The heat insulation component 5 includes a main gear 512. The upper arc cover 41 is rotatably connected to the central shaft of the main gear 512.

The arc-shaped heat insulation plate 54 matches the auxiliary arc block 46 and the arc plate 45. The edge of the arc-shaped heat insulation plate 54 is provided with an auxiliary groove 57. The auxiliary groove 57 matches the main circular block 312. The lower plate 36 is fixedly connected to symmetrical L-frames 35. The symmetrical L-frames 35 are respectively fixedly connected to racks 513. The racks 513 match the main gear 512.

[0056] The main gear 512 meshes with the auxiliary gear 511. The upper arc cover 41 is rotatably connected to the central shaft of the auxiliary gear 511. The central shaft of the auxiliary gear 511 is fixedly connected to the turntable 51. A mounting cylinder 52 is rotatably connected to the edge of the turntable 51.

[0058] The workflow of this embodiment is as follows:

[0059] When motor 23 rotates, it drives screw 22 to rotate. Screw 22 drives cross bar 313 to move along guide rod 21, realizing the movement of placement component 3 and rack 513. The main circular block 312 moves along straight groove 17. Circular block 38 moves sequentially along placement groove 13, one side arc groove 14, extrusion groove 15, another side arc groove 14, and translation groove 16 (or in the opposite direction). When moving along arc groove 14, circular block 38 drives slider 39 to move along vertical rod 311 in vertical groove 310. Lower circular block 38 drives lower plate 36 and lower push rod 37 to move. Upper circular block 38 drives upper plate 31, cylinder 316, spring 315, guide rod 314, and pressure plate 32 to move.

When the round block 38 moves along the other side of the arc groove 14, the pressure plate 32 and the lower push rod 37 move away from the carrier plate 33. When the round block 38 moves along the translation groove 16, the rack 513 gradually approaches and meshes with the main gear 512.

At this time, the arc-shaped insulation plate 510 blocks the L groove 44, achieving freezing and dormancy.

[0060] When the arc-shaped insulation board 510 swings, it drives the fixed gear 55 to swing. The fixed gear 55 drives the rotating gear 514 to rotate. The rotating gear 514 drives the inner rotating wheel 56 to rotate. The inner rotating wheel 56 drives the fixed shaft 59 to swing in the vertical sliding groove 515.

The bracket 517 drives the guide crossbar 516 to move along the guide block 48.

[0061] Example 3: This example is a further elaboration based on Example 2. The vertical plate 11 is provided with a first semi-circular tail groove 18 corresponding to the straight groove 17, and the upper arc cover 41 is provided with a second semi-circular tail groove 43 corresponding to the L groove 44. The first semi-circular tail groove 18 and the second semi-circular tail groove 43 are respectively matched with the main circular block 312.

[0062] When the main circular block 312 enters the first semi-circular tail groove 18 and the second semi-circular tail groove 43, it fits perfectly with both and matches the auxiliary groove 57. The arc-shaped insulation plate 54, the main circular block 312, the upper arc cover 41, the auxiliary arc block 46 and the lower box 42 form a relatively sealed area to reduce temperature loss.

[0063] A freezing method for a microcrystalline freezing system for beef preservation includes the following steps:

[0064] S1: Pour an appropriate amount of alcohol into the placement tank 49, operate the heat preservation device 47 to cool the placement tank 49 to about -18℃. At this time, the alcohol is similar to the boiling state of water.

[0065] S2: In the initial state, the round block 38 is placed in the placement slot 13. The beef is placed on the carrier plate 33, and the motor 23 is controlled to rotate, so that the placement component 3 and the rack 513 can move.

[0066] S3: When the circular block 38 moves along the arc groove 14 on one side, the pressure plate 32 and the lower push rod 37 move toward the direction of the carrying plate 33, so that the lower push rod 37 is inserted into the circular hole 34 and the pressure plate 32 contacts the beef;

[0067] S4: When the round block 38 moves along the extrusion groove 15, the spring 315 is slightly compressed, and the upper end of the lower push rod 37 is flush with the upper side of the carrier plate 33, so as to achieve beef leveling and moisture squeezing.

[0068] S5: When the circular block 38 moves along the arc groove 14 on the other side, the pressure plate 32 and the lower push rod 37 move away from the load plate 33.

[0069] S6: When the round block 38 moves along the translation groove 16, it enters the area formed by the upper arc cover 41 and the lower box 42 through the L groove 44. The arc-shaped heat preservation plate 54 closes the L groove 44, the heat preservation plate 510 leaves the placement groove 49, the carrying plate 33 moves above the placement groove 49, and the cold air achieves freezing of the beef through the round hole 34.

[0070] S7: After the freezing period ends, control the motor 23 to rotate in the opposite direction, so that the round block 38 moves to the initial position and the frozen beef is taken out.

[0071] In the initial state, the round block 38 is located in the placement slot 13, which facilitates the placement of beef. By setting the arc groove 14, the relative movement of the pressure plate 32 and the lower push rod 37 can be realized to squeeze the beef, flatten the beef, and squeeze out some water. By setting the round hole 34, it is convenient to squeeze and then freeze the beef.

[0072] By employing gear and rack meshing and gear meshing, the arc-shaped insulation plate 54 and the insulation plate 510 are moved synchronously. In the initial state, the arc-shaped insulation plate 54 is away from the L-groove 44, and the insulation plate 510 completely closes the placement groove 49, thus achieving alcohol insulation in the placement groove 49. After the gear and rack mesh, the carrying plate 33 enters the upper arc cover 41, the arc-shaped insulation plate 54 swings to block the L-groove 44, and the insulation plate 510 moves away from the placement groove 49, thus achieving cold air sealing in the area formed by the upper arc cover 41 and the lower box 42, reducing temperature loss.

[0073] By setting the retaining spring 53, the positions of the arc-shaped insulation plate 54 and the insulation plate 510 are maintained, which facilitates heat preservation and reduces temperature loss.

[0074] This device is equipped with a placement slot 13, an arc slot 14, a compression slot 15, an arc slot 16 and a translation slot 16 connected in sequence. The round block 38 is placed in the placement slot 13, and the pressure plate 32 is away from the carrying plate 33, which facilitates the placement of beef. The arc slot 14 facilitates the relative movement of the pressure plate 32 and the lower push rod 37 to compress the beef, flatten the beef and squeeze out some water. The round hole 34 facilitates the subsequent freezing while compressing.

[0075] The insulation component 5 of this device employs gear and rack meshing and gear meshing to achieve synchronous movement of the arc-shaped insulation plate 54 and the insulation plate 510. Initially, the arc-shaped insulation plate 54 is away from the L-groove 44, and the insulation plate 510 completely seals the placement groove 49, achieving alcohol insulation within the placement groove 49. After gear and rack meshing, the carrying plate 33 enters the upper arc cover 41, and the arc-shaped insulation plate 54 swings to block the L-groove 44. The insulation plate 510 moves away from the placement groove 49, sealing the cold air within the area formed by the upper arc cover 41 and the lower housing 42, reducing temperature loss. When the main circular block 312 enters the first semi-circular tail groove 18 and the second semi-circular tail groove 43, it perfectly fits both and matches the auxiliary groove 57. The arc-shaped insulation plate 54, the main circular block 312, the upper arc cover 41, the auxiliary arc block 46, and the lower housing 42 form a relatively sealed area, further reducing temperature loss.

[0076] The above-disclosed embodiments are merely specific examples of the present invention. However, the present invention is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
