Description

Technical Field

[0001] This invention relates to the field of freezing equipment technology, specifically to a freezing and shaping device for surimi processing. Background Technology

[0002] In the surimi processing process, cryogenic shaping equipment is a key piece of equipment used to shape and maintain a stable structure of the processed surimi through low-temperature treatment. The plate freezer is currently the most commonly used cryogenic shaping equipment in surimi processing. It places the surimi on a plate and uses low-temperature air to quickly freeze the surimi, so that it can achieve the effect of low-temperature shaping in a short time.

[0003] In the freeze-setting process of surimi processing, the surimi is usually packaged first, then placed in molds, and finally the molds are placed on the plates of a plate freezer for freezing. However, this method may cause some problems. On the one hand, the surimi packaging bags may stick to the molds, mainly due to increased friction caused by low temperatures, brittleness of the packaging bag material at low temperatures, and an uneven surface of the molds. On the other hand, although surimi packaging bags usually have good sealing and water resistance, if the sealing of the packaging bag is poor, the material properties are not good, or the surfaces of the packaging bag and the molds are not smooth enough, the surimi packaging bags may stick. If residual moisture remains on the surface, the moisture in the surimi may slowly release and freeze, forming an ice layer between the packaging bag and the mold tray. This further increases the difficulty of removing the surimi from the mold tray. In addition, when the plate freezer is used for cooling aquatic products for a long time, moisture inevitably remains on its plate surface. This moisture will form an ice layer during the freezing process, causing the mold tray to stick to the plate. When workers remove the mold tray, they often need to use tools such as pry bars. This not only increases the complexity and labor intensity of manual operation, but may also affect production efficiency. Therefore, based on the above problems, a freezing and shaping device for surimi processing is proposed. Summary of the Invention

[0010] Preferably, the adjusting rod has several adjusting screw channels of different sizes on its curved surface. The mating sleeve consists of an outer square sleeve and an inner guide block.

The heat exchange coil of the heat exchange section is connected to the evaporator of the refrigeration equipment group.

[0011] Preferably, the air chamber has pressure relief holes with front openings on both the left and right sides. The vent plate shell is disposed between the first drive arm and the second drive arm, and the left and right end faces of the vent plate shell are in contact with the first drive arm and the second drive arm.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. In this invention, the drive unit, the adjustable spacing component, the deployable mold, and the air supply unit are designed to drive the adjustable spacing component to operate. The adjustable spacing component can adjust the distance between each plate, and the air supply unit can supply air to the deployable mold. Combined with the change in the spacing between the plates, the deployable mold can be adjusted to close or unfold. This invention enables the freeze-setting equipment to close during the freezing process to preliminarily shape the fish paste, and unfold when it is taken out. This greatly facilitates the workers to quickly collect the frozen and shaped fish paste. It solves the problem that existing freeze-setting equipment generally uses molds when freezing and shaping fish paste, which not only makes it inconvenient to take out due to various factors, but also affects the overall production efficiency.

[0016] 2. In this invention, through the arrangement of the air supply section and the deployable module, after the deployable module is closed, drive arm one and drive arm two will fit against the inner side wall of the air chamber. At this time, the air inlet of the diverter plate can be connected to the ventilation section and the air supply section through the air chamber. At the same time, each exhaust head will be precisely inserted into the matching longitudinal air passage of each side sealing plate. In addition, spliced ​​air passage one, spliced ​​air passage two, and spliced ​​air passage three will be spliced ​​together to form a complete loop. Under this structural layout, the low-temperature airflow in the air chamber can enter the heat exchange plate shell through the air inlet and then pass through the exhaust head. The air is discharged into each of the corresponding longitudinal air channels. Then, the low-temperature airflow continues to flow and enters the ring channel formed by the spliced ​​air channel one, spliced ​​air channel two, and spliced ​​air channel three, and finally exits from the exhaust port. Throughout the process, the low-temperature airflow surrounds the fish paste and carries away the heat of the fish paste effectively. This allows for targeted freezing of the fish paste to set its shape, which not only improves freezing efficiency but also ensures the shaping and preservation of the fish paste during the freezing process. This process effectively avoids problems such as loss of nutrients and deterioration of taste that may occur due to excessive freezing time. Attached Figure Description

[0041] Please see Figure 1-23 The present invention provides a technical solution:

[0042] A freezing and shaping device for surimi processing includes a box section 1, a refrigeration unit 2, a drive unit 3, a spacing adjustment assembly 4, a flat plate 5, an air conveying unit 6, a deployable mold 7, a heat exchange unit 8, and a control box 9. The box section 1 includes a box body 11, with a front-opening storage cavity 12 on the inner side of the box body 11. A door 13 is hinged to the left side of the box body 11. A lower cavity 14 is located below the storage cavity 12 on the inner side of the box body 11. An air port 15 communicating with the storage cavity 12 is opened on the right side of the box body 11.

The output shaft of the motor 31 is fixedly connected to a sprocket 32 ​​located inside the storage cavity 12. Chain links 33 are fixedly connected to the outer sides of the adjusting rod 41. A chain belt 34 is sleeved on the outer side of a set of chain links 33 and the sprocket 32, and the chain belt 34 meshes with the sprocket 32 ​​and chain links 33. The adjusting rod 41 can be driven to rotate by the driving unit 3. A heat exchange unit 8 located inside the expansion shell 16 is installed on the left side of the refrigeration equipment group 2. The gas delivery unit 6 includes an air inlet pipe 61 fixed inside the right interface of the housing 11 and located inside the expansion shell 16. The left end of the air inlet pipe 61 is connected to a diversion shell 62, and the diversion shell... The right end face of 62 is fixedly connected to the right inner wall of the storage cavity 12. The left side of the diversion shell 62 is connected to several stainless steel telescopic corrugated pipes 63 that are aligned with each plate 5. The left end of each stainless steel telescopic corrugated pipe 63 is connected to a shaft tube 64. A connecting sleeve 65 is fixedly connected to the outside of the shaft tube 64, and the rear end of the connecting sleeve 65 is fixedly connected to the front end face of the plate 5. Several annular grooves 66 corresponding to each deployable mold 7 are opened on the outer curved surface of the shaft tube 64. Several through holes 67 that are set at equal angles and connected to the shaft tube 64 are opened at the annular grooves 66. An air pump 68 is installed on the air inlet pipe 61.The deployable mold body 7 includes a ventilation rotating part 71, a mold base 72, a drive frame 73, a side sealing plate 74, a flow divider 75, a rear sealing rail plate 76, a base frame 77, and a rail groove 78. The mold base 72 includes an inclined seat plate 721. An air cavity 722 with an upward opening is opened on the inner side of the seat plate 721. The left and right sides of the air cavity 722 have non-aligned rail openings 723. The front side of the air cavity 722 has a through-hole 724. A front panel 726 is fixedly connected to the front end of the upper end of the seat plate 721, and the front end face of the front panel 726 is on the same plane as the front end face of the seat plate 721. A rotating groove 727 is opened at the rear end of the seat plate 721. A venting rotating part 71 is installed at the location. The venting rotating part 71 includes a rotating sleeve 711 that is rotatably connected to the annular groove 66. The rear end of the rotating sleeve 711 is fixedly connected to the front end of the base plate 721. The rear end of the rotating sleeve 711 is connected to a venting plate shell 712 that passes through the insertion port 724 and is located inside the air cavity 722. A pair of transversely arranged through holes 713 are opened on the inner side of the venting plate shell 712. Several equidistant air outlets 714 are opened on both the left and right sides of the venting plate shell 712. Through this arrangement, the air supply part 6 can transport the airflow in the expansion shell 16 through the shaft tube 64 and the through hole 67 to the air cavity 722 of each deployable mold body 7. A drive frame 73 is installed at the air cavity 722. The drive frame 73 includes a drive arm 731 slidably connected to the left rail opening 723. A rail 732 is provided inside the crossbar of the drive arm 731. A drive arm 733 is slidably connected to the inner side of the rail 732, and the crossbar of the drive arm 733 is slidably connected to the right rail opening 723. Receiving grooves 734 are provided on the facing surfaces of the front bars of both the drive arm 731 and the drive arm 733. Tension springs 735, passing through openings 713, are fixedly connected between the inner walls of the left and right receiving grooves 734. Side sealing plates 74 are fixedly connected to the opposite sides of the crossbars of both the drive arm 731 and the drive arm 733, and the side sealing plates 74 are both located on the left side of the mold base 72. On the right sides; a diversion plate 75 is installed on the upper side of the mold base 72, and a horizontally arranged base frame 77 is provided on the upper side of the mold base 72. The upper end face of the base frame 77 is fixedly connected to the lower end face of the plate 5. Track grooves 78 are opened on both the left and right sides inside the base frame 77. A rear sealing track plate 76 is installed on the rear side of the mold base 72. The rear sealing track plate 76 includes a rear enclosure plate 761 that is rotatably connected to the rotating groove 727. Track blocks 763 that are slidably connected to the track grooves 78 are fixedly connected on both the upper left and right sides of the rear enclosure plate 761. This arrangement allows the expandable mold body 7 to close to shape the fish paste, and to unfold when it is taken out, which greatly facilitates the staff to quickly collect the frozen and shaped fish paste.The adjusting rod 41 has several adjusting screw channels of different sizes on its curved surface. The mating sleeve 42 consists of an outer square sleeve and an inner guide block. The inner guide blocks of the mating sleeve 42 are all located inside the adjusting screw channels of the adjusting rod 41. This arrangement allows the rotation of the adjusting rod 41 to drive the displacement of each mating sleeve 42. The heat exchange section 8 consists of a heat exchange coil and a circulating liquid pump installed on the heat exchange coil. The right rear air inlet vertical pipe of the air inlet pipe 61 is located directly below the heat exchange coil of the heat exchange section 8. This arrangement allows the air inlet pipe 61 to draw air from the heat exchange coil. All extracted gas flows will exchange heat with the heat exchange coils of heat exchange section 8, ensuring that the extracted gas is a low-temperature gas. Refrigeration unit 2 consists of an evaporator, compressor, condenser, and expansion valve. The heat exchange coils of heat exchange section 8 are connected to the evaporator of refrigeration unit 2. This arrangement allows the heat exchange coils of heat exchange section 8 to be pre-filled with chilled water. Driven by a circulating liquid pump, the water exchanges heat with the environment to lower the temperature inside the expansion shell 16, and exchanges heat with the refrigerant circulating in the evaporator of refrigeration unit 2, thus reducing the temperature of the chilled water. The system maintains a consistently low temperature. Both sides of the air chamber 722 are connected to pressure relief holes 725 with front openings. This design forces the gas at point B of the air chamber 722 to exit through the pressure relief holes 725 during the opposite displacement of drive arm 731 and drive arm 733, thus preventing the drive arms 731 and 733 from being unable to move in opposite directions due to air pressure. A venting plate 712 is positioned between drive arm 731 and drive arm 733, and the venting plate 712 has front openings on both sides. The end faces of both drive arms 731 and 733 are in contact with each other. The thickness of drive arms 731 and 733 is the same as the depth of the air chamber 722. The lower end faces of drive arms 731 and 733 are in contact with the lower inner wall of the air chamber 722, and the upper end faces of drive arms 731 and 733 are in contact with the lower end face of the flow divider 75. This arrangement prevents the low-temperature airflow entering the air chamber 722 from leaking out through the pressure relief hole 725 due to gaps.

[0043] like Figures 11-12 , Figures 14-15 , Figures 17-19 , Figures 21-22As shown, a pair of vertically distributed spliced ​​air passages 728 are provided at the rear end face of the front panel 726. A pair of horizontally distributed exhaust holes 729 are provided on the front side of each spliced ​​air passage 728. A pair of vertically distributed spliced ​​air passages 762 are provided at the front end face of the rear panel 761. The side sealing plate 74 includes a side panel 741 fixedly connected to either drive arm 731 or drive arm 733. Several equidistant longitudinal air passages 742 are provided on the side of the side panel 741 near the mold base 72. A pair of vertically distributed spliced ​​air passages 743 are provided on the side of the side panel 741 near the mold base 72, and all spliced ​​air passages 743 are connected to the longitudinal air passages 742. The flow divider 75 includes a component fixed to the base plate 721. The heat exchange plate shell 751 on the side has several equidistant air inlets 752 on both the left and right sides of its lower end face. Exhaust heads 753 are connected to both sides of the heat exchange plate shell 751. This arrangement allows the deployable mold body 7 to close, and the drive arm 1 731 and drive arm 2 733 to fit against the inner side wall of the air chamber 722. At this time, the air inlets 752 of the diverter plate 75 can connect to the ventilation section 71 and the air delivery section 6 through the air chamber 722. Simultaneously, each exhaust head 753 will be precisely inserted into the matching longitudinal air passages 742 of each side sealing plate 74. Furthermore, the splicing air passage 1 728, splicing air passage 2 743, and splicing air passage 3 762 will be spliced ​​together to form a complete ring. Under this structural layout, the air chamber 722... The low-temperature airflow enters the heat exchange plate shell 751 through the air inlet 752, and then exits through the exhaust head 753 into each matching longitudinal air channel 742. The low-temperature airflow continues to flow, entering the annular channel formed by the first splicing air channel 728, the second splicing air channel 743, and the third splicing air channel 762, and finally exits from the exhaust port 729. Throughout this process, the low-temperature airflow surrounds the surimi, undergoing thorough heat exchange and effectively removing heat from the surimi, enabling targeted freezing and shaping. The diameter of the exhaust head 753 is the same as the inner diameter of the matching longitudinal air channel 742, and the exhaust heads 753 are all laterally aligned with the matching longitudinal air channels 742. This arrangement allows the exhaust heads 753 to be inserted when the deployable mold 7 is closed. The distance between the air inlet 752 and the inner wall of the air chamber 722 is the same as the width of the front rod of the first drive arm 731 and the second drive arm 733. This arrangement allows the deployable mold 7 to be closed, and the first drive arm 731 and the second drive arm 733 will fit against the inner wall of the air chamber 722. At this time, the air inlet 752 of the diverter plate 75 can be connected to the ventilation section 71 and the air conveying section 6 through the air chamber 722. The heat exchange plate shell 751, the seat plate 721, the front plate 726, the side plate 741, the rear plate 761 and the plate 5 have the same high thermal conductivity. This arrangement shows that the deployable mold 7 has excellent thermal conductivity, which enables efficient heat exchange with the fish paste in a low-temperature environment and improves the freezing efficiency of the fish paste.

[0044] Workflow: The freezing and shaping operation of the fish paste by the freezing and shaping equipment is as follows: Note 1: All electrical components of this equipment are externally powered and centrally controlled through control box 9; Note 2: The heat exchange coils of the heat exchange section 8 are pre-filled with chilled water. Driven by a circulating liquid pump, it exchanges heat with the environment to lower the temperature inside the expansion shell 16, and exchanges heat with the refrigerant circulating in the refrigeration unit 2, keeping the chilled water at a consistently low temperature. The condenser of the refrigeration unit 2 needs to be pre-connected to the cooling water of an external cooling tower via a pipe to allow heat exchange between the cooling water and the refrigerant, thus ensuring the normal circulation of the refrigerant within the refrigeration unit 2; Note 3: The fish paste needs to be pre-packaged during freezing and shaping. Packaging: When placing the fish paste, the staff first uses a trolley to transport a large amount of packaged fish paste to the front of the storage chamber 12. At this time, each deployable mold 7 is fully deployed, so that the staff can easily place the packaged fish paste directly into the inner area of ​​the deployable mold 7 through the opening between the front panel 726 and the base frame 77. Then the fish paste is laid flat on the inclined diversion plate 75 and held in place by the front panel 726 to ensure its stable position. Through the above steps, the staff can complete the placement of each bag of plastic-packaged fish paste in a simple and convenient way.Finalization Operation: After the fish paste is placed, the operator can close the door 13 to seal the storage chamber 12. At this time, the refrigeration unit 2 and the heat exchange unit 8 are started by operating the control box 9 to achieve rapid cooling of the expansion shell 16. Then, the motor 31 of the drive unit 3 is started again by the control box 9. The operation of the motor 31 drives the sprocket 32 ​​to rotate. The sprocket 32, through the chain belt 34 meshing with it, further drives each chain link 33 to rotate 360 ​​degrees. The rotation of the chain link 33 will cause the adjusting rod 41 to rotate 360 ​​degrees accordingly. The rotation of the adjusting rod 41 causes each mating sleeve 42 to shift, which in turn causes each connected plate 5 to move downwards, gradually reducing the distance between the plates 5. This completes the adjusting operation of the adjusting assembly 4 on the plates 5. As the plates 5 move downwards, the base frames 77 of each deployable module 7 also move downwards. Under the combined effect of the base frames 77 moving downwards and the distance between the plates 5 decreasing, the rear end plate 761 of the rear sealing rail plate 76 moves downwards, causing the rail block 763 to move slightly backwards guided by the rail groove 78. The rearward displacement applies pressure to the mold base 72, causing the mold base 72 and the ventilation rotating part 71 to rotate backward around the shaft tube 64 as the fulcrum. This makes the rotated mold base 72 horizontal and tightly fit against the lower plate 5. At the same time, the base frame 77 tightly fits against the upper end face of the front panel 726, completing the initial closing of the deployable mold body 7. Finally, the air pump 68 of the air supply part 6 is started through the control box 9. The air pump 68 draws low-temperature airflow from the expansion shell 16 through the air inlet pipe 61 and introduces it into the distribution shell 62. Subsequently, the low-temperature airflow passes through each stainless steel extension The bellows 63 is diverted into each shaft tube 64 and discharged into the ventilation section 71 of each deployable module 7 through the through hole 67. The low-temperature airflow passes through the rotating sleeve 711 and the ventilation plate shell 712, and is discharged from the air outlet 714 into the air chamber 722. As the low-temperature gas in the air chamber 722 increases, it will exert pressure on the drive arm 1 731 and drive arm 2 733, forcing them to move in opposite directions. During the process of the drive arm 1 731 and drive arm 2 733 moving in opposite directions, the gas at point B of the air chamber 722 will be discharged from the pressure relief hole 725, for example. Figure 12 As shown, the opposing displacements of drive arm 731 and drive arm 733 will cause the left and right side sealing plates 74 to move towards the mold base 72 and the fish paste area, until the side sealing plates 74 are tightly fitted with the base plate 721, the front panel 726, and the rear panel 761, completing the closing. At this time, the side sealing plates 74, the base plate 721, the flow divider plate 75, the front panel 726, and the rear panel 761, together with the base frame 77, form a complete mold plate, as shown. Figure 20As shown, it can effectively enclose and shape the surimi on the inner side, thus completing the initial shaping operation of the surimi; Freezing operation: After the deployable mold 7 is closed, drive arm one 731 and drive arm two 733 will be tightly fitted with the side wall of the air chamber 722. At this time, the air inlet 752 of the diverter plate 75 can be connected to the ventilation rotating part 71 through the air chamber 722. At the same time, each exhaust head 753 will be accurately inserted into the matching longitudinal air passage 742 of each side sealing plate 74. In addition, splicing air passage one 728, splicing air passage two 743 and splicing air passage three 762 will be spliced ​​together to form a complete ring channel. Under this structural layout, the air... The low-temperature airflow within cavity 722 smoothly enters the heat exchange plate shell 751 through the air inlet 752, and then exits through the exhaust head 753 into each matching longitudinal air passage 742. The low-temperature airflow continues to flow, entering the annular channel formed by spliced ​​air passage one 728, spliced ​​air passage two 743, and spliced ​​air passage three 762, and finally exits from the exhaust port 729. Throughout this process, the low-temperature airflow surrounds the fish paste on the upper side of the heat exchange plate shell 751, fully exchanging heat with the fish paste and effectively removing its heat, thereby accelerating the freezing efficiency of the fish paste. Through this carefully designed operating procedure, targeted freezing of the fish paste can be achieved. Freezing sets the shape, which not only improves freezing efficiency but also ensures the shaping and preservation of the fish paste during freezing. This process effectively avoids problems such as nutrient loss and deterioration in taste that may occur due to excessive freezing time. Removal procedure: After the freezing time is reached, the operator opens the door 13, revealing the internal storage cavity 12, the adjusted spacing component 4, and the closed deployable molds 7. At this time, under the control of the control box 9, the drive unit 3 drives the adjusted spacing component 4 to move the flat plates 5 upwards and reset. This action causes the mold base 72 of each deployable mold 7 to return to an inclined state, and the front panel 726... An opening reappears between the base frame 77 and the air supply unit 6, heat exchange unit 8 and refrigeration equipment group 2 are controlled to stop operating, so that the air supply unit 6 no longer supplies air to each deployable module 7. As the air supply stops, each tension spring 735 in the air cavity 722 can contract, driving the drive arm 1 731 and drive arm 2 733 to reset and move in opposite directions. Then, the side panels 741 on both sides reset and move in opposite directions, so that each deployable module 7 resets from the closed state to the unfolded state through mechanical reset transmission. Through the above operations, even if an ice layer is generated between the plate 5 and the deployable module 7 during freezing, it will be directly separated during the mechanical reset process.Even if an ice layer forms between the fish paste and the unfoldable mold 7 during freezing, the graspable area of ​​the fish paste will increase after the mold 7 is unfolded. This makes it easier for workers to easily remove the fish paste from the unfolded mold 7. The unique unfoldable mold 7 allows the freeze-setting equipment to close during freezing for initial shaping of the fish paste, and then unfold again for removal. This greatly facilitates the quick collection of frozen and shaped fish paste, solving the problem that existing freeze-setting equipment typically uses molds for freezing and shaping fish paste, which not only makes removal inconvenient due to various factors but also affects overall production efficiency.
