Description

Technical Field

[0001] This invention relates to the field of food processing technology, specifically to a shredding device and a continuous shredding method for bean curd. Background Technology

[0002] Dried scallops, also known as scallop adductor muscles, are a type of seafood product made from the dried adductor muscles of scallops and other shellfish. They are highly favored by consumers for their delicious flavor and rich nutritional value. Processing dried scallop pieces into loose scallop strands is an important pre-processing step in the production of ready-to-eat seafood products and seasoning packets.

[0003] Currently, the scallop fiber production process mainly relies on traditional manual methods. The typical process involves first soaking or boiling the scallop fibers to soften them, then using simple pressing devices (such as rollers) to flatten the softened fibers and disperse them into filaments. This production method suffers from low mechanization and low efficiency, as well as poor fiber formation and insufficient dispersion of the scallop muscle fibers. This results in a high rate of fiber adhesion (over 80%) in the finished product, along with high moisture content, severely impacting product quality and subsequent applications.

[0004] Therefore, developing a bedding method that enables continuous operation, effectively reduces bedding adhesion, maintains the integrity of muscle fibers, and ensures stable quality is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0005] The purpose of this invention is to provide a beet silk making device and a continuous silk making method, which can solve the technical problems of low beet silk production efficiency and unstable product quality mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] The first aspect of the present invention provides a beet shaving device, comprising: a shaving tank, the shaving tank being vertically arranged and having an inlet at the top and an outlet at the bottom; a primary shaving assembly and a secondary shaving assembly disposed within the shaving tank and distributed vertically, the primary shaving assembly comprising a primary mounting bracket, a primary main shaft rotatably connected to the primary mounting bracket, and a primary blade assembly fixedly connected to the top end of the primary main shaft, the blades of the primary blade assembly having a blunt striking portion on their side ends, the blunt striking portion being used to apply a blunt striking action to the beet during rotation; the secondary shaving assembly comprising a secondary mounting bracket, a secondary main shaft rotatably connected to the secondary mounting bracket, and a secondary blade assembly fixedly connected to the top end of the secondary main shaft, the blades of the secondary blade assembly having a combing portion on their side ends, the combing portion being used to apply a combing action to the beet after primary shaving during rotation.

[0008] In a preferred embodiment, the overall diameter of the first-stage blade assembly is smaller than the overall diameter of the second-stage blade assembly.

[0009] In a preferred embodiment, the blades of both the first-stage blade assembly and the second-stage blade assembly have an inclination angle of 5° to 10° relative to the horizontal plane of rotation.

[0010] In a preferred embodiment, the blade thickness of both the primary blade assembly and the secondary blade assembly is 3-5 mm.

[0011] In a preferred embodiment, the combing section is configured as a sawtooth structure with a tooth spacing of 0.5-1 mm and a tooth depth of 0.5-1 mm.

[0012] In a preferred embodiment, a material guide channel is provided between the primary mounting bracket and the secondary blade. The axial cross-section of the material guide channel is an inverted trapezoid, with its top end fixedly connected to the inner wall of the wire-forming tank and its lower end opening directly above the secondary blade assembly.

[0013] In a preferred embodiment, the primary wire-forming assembly and / or the secondary wire-forming assembly are further provided with an anti-aggregation mechanism, which is fixedly connected to the corresponding main shaft and located above the blade assembly, for pushing the material to the blade working surface.

[0014] In a preferred embodiment, the anti-aggregate mechanism is a rotary blade structure or a conical pedestal structure.

[0015] A second aspect of the present invention provides a continuous wire-forming method, employing the bedding wire-forming device described above, comprising the following steps:

[0016] S1: Wash and drain the dried scallop pieces to allow them to absorb water and swell;

[0017] S2: Crack the drained scallops to make them split into multiple pieces or flattened shapes;

[0018] S3: The crushed scallops are continuously steamed to cook them.

[0019] S4: While the steamed and cooked scallops are still hot, they are fed into the scallop filament-making device. First, the primary filament-making component bluntly beats the scallops to initially disperse the muscle fibers, and then the secondary filament-making component combs them apart to completely separate the muscle fibers.

[0020] S5: Cool the shredded beeswax and collect it.

[0021] In a preferred embodiment, the blade speed of the primary wire-forming assembly is 1400-1500 rpm, the blade speed of the secondary wire-forming assembly is 1800-2000 rpm, and the primary and secondary wire-forming assemblies rotate in opposite directions.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] The scallop filament processing device provided by this invention, by setting a two-stage filament processing structure in the same tank, and setting the first-stage blade to a semi-circular blunt cross section and the second-stage blade to a serrated cross section, realizes the process of first blunting and then combing the cooked scallop filaments, effectively maintaining the length and toughness of the filaments. At the same time, by optimizing the process parameters of washing, draining, pre-cracking, continuous cooking and cooling processes, the filament adhesion rate is significantly reduced from more than 80% in the traditional method to less than 10%. The finished product has low moisture content and stable quality, and the whole process realizes automated continuous production, which significantly improves production efficiency, reduces labor costs and labor intensity, and is suitable for large-scale industrial filament processing of dried scallop filaments.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0037] Example 1

[0038] See Figures 1-2 This embodiment discloses a bedding wire-making device 8, including a frame 81, a wire-making tank 82 fixedly connected to the frame 81, and a primary wire-making component 83 and a secondary wire-making component 84 disposed in the wire-making tank 82.

[0039] Specifically, the shaving tank 82 is vertically arranged, with an inlet 821 at the top and an outlet 822 at the bottom. The primary shaving assembly 83 and the secondary shaving assembly 84 are distributed vertically within the shaving tank 82, with the primary shaving assembly 83 located at the top and the secondary shaving assembly 84 at the bottom. During operation, the scallops processed by the continuous cooking machine 6 enter the shaving tank 82 through the inlet 821. First, the primary shaving assembly 83 performs preliminary shaving, loosening the scallop muscle fibers. Then, the secondary shaving assembly 84 performs a second shaving process, further dispersing the muscle fibers. The scallop fibers, after secondary shaving, are discharged through the outlet 822 to the subsequent cooling process.

[0040] The primary wire-forming assembly 83 includes a primary mounting bracket 831 fixedly connected to the inner wall of the wire-forming tank 82, a primary main shaft 832 rotatably connected to the center of the primary mounting bracket 831 via bearings, and a primary blade assembly 833 fixedly connected to the top of the primary main shaft 832. The primary main shaft 832 is driven to rotate by a primary drive variable frequency motor 835 fixed to the outside of the wire-forming tank 82. The output shaft of the primary drive variable frequency motor 835 is connected to the primary main shaft 832 via a transmission belt mechanism, which is sealed to the wire-forming tank 82 through a cover. The transmission structure in this embodiment adopts existing technology, and its specific structure will not be described in detail here.

[0041] The overall diameter of the first-stage blade assembly 833 occupies approximately two-thirds of the inner diameter of the wire-forming can 82. This arrangement is designed to provide sufficient passage space between the material and the inner wall of the can and the blades. Figure 3 and Figure 4 The individual blades in the first-stage blade assembly 833 have a specific shape to blunt the impact of the falling slag. Specifically, the blade thickness of the first-stage blade is set to 3-5mm, and its side end is provided with a blunting part 834. The cross-section of the blunting part 834 has a blunt structure with rounded edges, which can blunt the impact of the slag. For example, the blunt structure can adopt a semi-circular, elliptical, or other rounded edge configurations. In this embodiment, a semi-circular structure with lower manufacturing difficulty and cost is preferred. Furthermore, the first-stage blade has an inclination angle of 5° to 10° relative to the horizontal rotation plane to achieve reasonable control of wind speed and prevent excessive wind speed. In this embodiment, by providing the blunting part 834 on the first-stage blade, the blade edge is rounded and does not have a sharp shearing edge. When the first-stage drive variable frequency motor 835 drives the first-stage main shaft 832 and the first-stage blade to rotate counterclockwise at a speed of 1400-1500rpm, the blade blunts the falling high-temperature slag. This blunt beating action allows the interlocking fibers to be gently separated by beating when they are in a state of thermal expansion, rather than being cut, thus effectively maintaining the length and integrity of the filaments and avoiding the problem of short and broken finished products caused by fiber breakage.

[0042] The secondary wire-forming assembly 84 includes a secondary mounting bracket 841 fixedly connected to the inner wall of the wire-forming tank 82, a secondary main shaft 842 rotatably connected to the center of the secondary mounting bracket 841 via bearings, and a secondary blade assembly 843 fixedly connected to the top of the secondary main shaft 842. The secondary main shaft 842 is also driven to rotate by a secondary drive variable frequency motor 845 fixed to the outside of the wire-forming tank 82. Unlike the primary blades, in this embodiment, the overall diameter of the secondary blade assembly 843 approximately matches the inner diameter of the wire-forming tank 82 (a small gap is required between them to support the rotation of the secondary blades), that is, the overall diameter of the primary blade assembly 833 is approximately two-thirds of the overall diameter of the secondary blade assembly 843. Figure 5 and Figure 6 The thickness of the secondary blade is also set to 3-5mm, and its side end has a combing section 844 with a serrated cross-section. The serration spacing of the combing section 844 is set to be slightly larger than the sum of the diameters of two bermuda muscle fibers, specifically about 0.5-1mm, and the tooth depth is also 0.5-1mm, so as to comb the bermuda fibers after blunt beating. The secondary blade also has an inclination angle of 5° to 10°. During operation, the secondary drive variable frequency motor 845 drives the secondary main shaft 842 and the secondary blade to rotate clockwise at a speed of 1800-2000rpm. This high speed, combined with the serrated blade, combs the bermuda fibers that are partially stuck together after primary beating.

[0043] It should be noted that the first-stage and second-stage blades rotate in opposite directions (first-stage counterclockwise, second-stage clockwise) to enhance wire beating intensity and efficiency.

[0044] Further, see again Figure 1 To prevent material from falling directly through the annular gap between the secondary blade and the inner wall of the fiber-forming tank 82 without proper treatment during the fiber-forming process, this embodiment provides a guide channel 85 with an inverted trapezoidal axial cross-section between the primary mounting bracket 831 and the secondary blade. The top edge of the guide channel 85 is fixedly connected to the inner wall of the fiber-forming tank 82, and its lower opening faces directly above the secondary blade assembly 843. The inner wall of the guide channel 85 has a slope towards the center. After primary fiber-forming, the material falls into the guide channel 85 under gravity, is guided along its sloping inner wall, and gathers above the secondary blade, ensuring that all material passes through the working area of ​​the secondary blade.

[0045] In practical applications, the primary and secondary drive variable frequency motors 845 are started to drive the primary spindle 832 and the secondary spindle 842 to rotate respectively. The primary impeller rotates counterclockwise, and the secondary impeller rotates clockwise. The cooked scallops enter the shaving tank 82 through the feed inlet 821. First, they undergo preliminary shaving by the primary shaving assembly 83 to loosen the scallop muscle fibers. Then, the material falls freely along the tangential direction of the primary impeller, passes through the guide channel 85, and undergoes secondary shaving by the secondary shaving assembly 84 to further loosen the muscle fibers. The scallop fibers, after secondary shaving, fall freely along the tangential direction of the secondary impeller and are discharged through the discharge outlet 822 to the subsequent cooling process.

[0046] Example 2

[0047] The bedding wire-making device 8 provided in this embodiment has a roughly the same structure as that in Embodiment 1. For the sake of simplicity, only the differences will be described in detail here.

[0048] See Figure 3 and Figure 5 In this embodiment, the primary wire-cutting assembly 83 and the secondary wire-cutting assembly 84 are also provided with anti-aggregation mechanism 86. This mechanism is used to prevent the splattered or falling shavings from accumulating on the upper end face of the blade assembly during the wire-cutting process, so as to avoid the material from being unable to be effectively processed by the blade and remaining for a long time, which would lead to material deterioration or affect the operation of the equipment.

[0049] Specifically, the anti-aggregation mechanism 86 is fixedly connected to the primary spindle 832 or the secondary spindle 842 and is set above the corresponding blade assembly. It rotates synchronously with the primary or secondary blades. By utilizing the centrifugal force and thrust generated during rotation, it can continuously push the material that falls to the center outward, so that it returns to the effective working area of ​​the blade and is then processed normally.

[0050] For example, the anti-aggregate mechanism 86 can employ a swivel structure, which includes a central sleeve fixedly connected to the main shaft and two to four radial blades evenly distributed around the sleeve in a circumferential direction. The overall diameter of the swivel structure is smaller than the diameter of the first-stage blade assembly 833 to ensure that it can cover the main area of ​​the upper end face of the blade assembly during rotation. When the main shaft rotates, the blades of the swivel structure rotate with it, generating an outward centrifugal thrust that pushes the accumulated material onto the blade surface.

[0051] As another example, the anti-aggregation mechanism 86 can also employ a conical pedestal structure. This conical pedestal structure is coaxially fixed to the main shaft and located above the blade assembly, and has a smooth conical surface with a diameter that gradually increases from top to bottom. When material falls onto the conical pedestal, under the action of gravity and the slight vibrations generated by the rotation of the main shaft, the material will automatically slide down along the smooth conical surface onto the blade surface, which can also effectively prevent material accumulation.

[0052] Example 3

[0053] See Figures 7-9 Based on the bedding wire-making device 8 provided in Embodiment 1 or Embodiment 2, this embodiment discloses a continuous wire-making method. In this embodiment, unless otherwise specified, the equipment used is conventional equipment. The continuous wire-making method includes the following steps:

[0054] S1: Feeding, washing and draining

[0055] The dried scallops are evenly spread on the feeding area 1 of the feeding conveyor belt 2 and fed into the washing machine 3. Inside the washing machine 3, the scallops are continuously rinsed using a combination of air bubbles and water spray for 10 to 20 minutes. This step removes dust, mud, and other impurities from the surface of the scallops and dissolves and removes approximately 2% to 5% of the salt by weight. Simultaneously, the dried scallops absorb approximately 5% to 10% of the water during the washing process. After washing, the scallops are conveyed to the draining conveyor belt 4, where they remain for 10 to 15 minutes to allow the water to fully penetrate the scallop muscle fibers, promoting fiber swelling and preparing them for subsequent crushing and cooking.

[0056] S2: Pre-fracturing

[0057] After being drained, the spun fibers pass under the powered pressure roller 5 on a conveyor belt. This roller applies a stable crushing action to the spun fibers, splitting the intact column into 2 to 6 segments, or pressing it into a flat structure approximately 2 to 3 millimeters thick. This pre-crushing treatment disrupts the original dense cylindrical structure of the spun fibers, increasing the surface area. This not only facilitates the uniform penetration of steam heat and shortens cooking time, but more importantly, it initially breaks down the binding force between the muscle fiber bundles, thereby significantly improving the efficiency of the subsequent fiber-forming process.

[0058] S3: Continuous steaming

[0059] The fractured scallops enter a continuous steam cooker 6, where high-temperature steam provides the heat source, allowing the scallops to be dry-steamed in a steam atmosphere of 95°C to 105°C for 15 to 20 minutes. During this process, the scallop muscle fibers continue to absorb water and swell, while the myofiber proteins denature and mature due to heat. Under the combined action of heat and moisture, the scallop flaps produced by pre-fracture further crack, and the adhesion between fiber bundles is significantly weakened. By precisely controlling the heating temperature and time of this step, the moisture content and degree of maturation of the scallop fibers can be synergistically adjusted.

[0060] S4: Two-stage wire beating

[0061] After cooking, the temperature of the scallops is maintained above 90°C. The hot scallops are quickly transferred from the cooker 6 to the feed inlet 821 of the scallop shredding device 8 by the first lifting conveyor 7, and then fed into the shredding tank 82 while still hot.

[0062] The fibers first enter the primary beating zone. The primary drive variable frequency motor 835 drives the primary blades to rotate counterclockwise at 1400-1500 rpm. Because the primary blades have a semi-circular blunt cross-section, this stage primarily applies a blunt beating effect to the fibers. This beating process initially disperses the fiber fibers, forming loose rod-shaped structures with a diameter of 0.5 to 3 mm. The fiber temperature drops to approximately 75°C, and the fiber adhesion rate decreases to approximately 45%.

[0063] The material, after primary fiber beating, passes through the guide channel 85 under gravity and falls into the secondary fiber beating area. At this point, the fiber temperature remains above 70°C, and the fibers become more resilient due to the temperature drop. The secondary drive variable frequency motor 845 drives the secondary blades to rotate clockwise at a relatively high speed of 1800-2000 rpm. Because the secondary blades have a serrated side section, this stage primarily applies a combing effect to the material. After this step, the fiber muscle fibers are completely fluffy and resilient, with the adhesion rate reduced to below 10%, forming rod-shaped fibers with a diameter of 0.5 to 1.5 mm.

[0064] S5: Cooling and Collection

[0065] The filaments discharged from the discharge port 822 of the filament-making device are conveyed to the cooling conveyor belt 10 via the second lifting conveyor 9 or other enclosed conveying device. On the cooling conveyor belt 10, the filaments are cooled and lowered to below 30°C by the negative pressure provided by the cooling fan 11. Finally, the cooled finished filaments are bagged and immediately sent to a cold storage for preservation or freezing.

[0066] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.
