Description

Technical Field

[0001] This invention relates to the field of seaweed production technology, specifically to a continuous roasting device for seaweed. Background Technology

[0002] Nori is a thin, sheet-like food made from fresh laver through processes such as pulping, sheeting, drying, and baking. Rich in protein, dietary fiber, iodine, calcium, and various vitamins, it is considered a nutrient-dense healthy snack and is widely used as a side dish, sushi wrapper, and seasoning, making it a popular consumer choice. The production of nori involves numerous precise processes, including laver cultivation, harvesting, cleaning, pulping, sheeting, drying, baking, seasoning, slicing, and packaging. Each process is interconnected, with the drying and baking stages having a particularly significant impact on the final product's color, aroma, and crispness. Therefore, precise control of temperature, humidity, and hygiene is essential at each stage to achieve the unique thin, crisp, and fragrant flavor of nori.

[0003] However, seaweed is thin and loosely structured. During the crucial baking process, the high temperature and mechanical vibration during transport can easily cause seaweed surface debris to fall off. These debris, rich in protein and other organic components, have strong adhesive properties and easily remain in the gaps and surfaces of the conveyor belt. As the production line continues to operate, the residual debris accumulates in the warm and humid environment, gradually becoming a favorable breeding ground for microorganisms. If the conveyor belt is not cleaned in a timely and thorough manner, microorganisms will proliferate, even leading to a serious exceedance of the total bacterial count. This can result in off-odors, mold, and other quality deterioration problems in the finished product, ultimately seriously affecting the safety and commercial value of the seaweed and hindering the stable improvement of product quality. Summary of the Invention

[0004] This invention provides a continuous seaweed roasting device. By using an air nozzle, residual debris on the tow bar can be blown off, keeping the tow bar clean and preventing the growth of a large number of microorganisms on its surface, thereby improving the final quality of the seaweed. Furthermore, the tow bar can rotate back and forth, further enhancing the cleaning effect. This solves the problem mentioned in the background art of seaweed debris remaining on the conveyor belt, affecting the quality of the seaweed.

[0005] This invention provides the following technical solution: A continuous seaweed roasting device includes a frame with a protective cover fixedly mounted on it. A heating device is installed inside the protective cover. The device also includes: a roller shaft rotatably mounted inside the protective cover; two symmetrically arranged conveyor chains are mounted on the roller shaft, and equally spaced tow rods are rotatably mounted between the two conveyor chains; a nozzle is fixedly mounted on the inner bottom of the protective cover, and an air nozzle facing the roller shaft is mounted at the lower end of the nozzle; a drive unit is provided inside the protective cover, which drives the tow rods to rotate when the tow rods move below the air nozzles.

[0006] As a preferred embodiment of the present invention, the driving unit includes a horizontal plate installed on the inner wall of the protective cover, and a driving wheel is fixedly installed at the end of the roller shaft. When the roller shaft moves to a position corresponding to the horizontal plate, the horizontal plate will push the driving wheel to rotate.

[0007] As a preferred embodiment of the present invention, the horizontal plate is slidably connected to the inner wall of the protective cover, a disc is rotatably mounted inside the protective cover via a rotating shaft, a push rod is rotatably mounted on the axial end face of the disc, and the other end of the push rod is rotatably connected to the outer wall of the horizontal plate. The disc, the push rod, and the horizontal plate constitute a crank-slider mechanism. A drive motor is fixedly mounted inside the protective cover, and the output shaft of the drive motor is connected to the rotating shaft via two meshing transmission gears.

[0008] As a preferred embodiment of the present invention, a receiving box with an opening facing the air nozzle is installed at the bottom of the protective cover. The bottom of the receiving box is provided with a discharge port. A baffle with an opening facing downward is fixedly installed at the top of the receiving box through a connecting frame. The air nozzle is located inside the baffle.

[0009] As a preferred embodiment of the present invention, the receiving box is slidably connected to the inner wall of the protective cover, and the receiving box vibrates up and down inside the protective cover during the reciprocating horizontal movement of the horizontal plate.

[0010] As a preferred embodiment of the present invention, a limiting block is fixedly connected to the outer wall of the receiving box, a spring is installed between the limiting block and the inner bottom of the protective cover, a plurality of protrusions are fixedly installed at equal intervals on the bottom of the horizontal plate, and a roller is rotatably installed on the outer wall of the receiving box, the roller pressing against the lower end surface of the horizontal plate.

[0011] As a preferred embodiment of the present invention, a telescopic airbag is installed inside the protective cover, and an air intake pipe and an exhaust pipe are fixedly connected to each of the two telescopic airbags. The end of the exhaust pipe is fixedly connected to and communicates with the nozzle.

[0012] As a preferred embodiment of the present invention, a symmetrically arranged fixing plate is fixedly connected inside the protective cover, and two symmetrically arranged pressure plates are fixedly installed on the horizontal plate, and the telescopic airbag is fixedly installed between the fixing plate and the pressure plate.

[0013] As a preferred embodiment of the present invention, a strip plate is fixedly installed inside the protective cover, and a plurality of upper and lower short plates are fixedly connected to the strip plate. The upper and lower short plates are located on the upper and lower sides of the drive wheel, respectively, and the upper and lower short plates are staggered.

[0014] As a preferred embodiment of the present invention, the inner bottom of the receiving box is recessed towards the discharge port, so that the shape of the receiving box is funnel-shaped.

[0015] Compared with the prior art, the present invention provides a continuous roasting device for seaweed, which has the following beneficial effects: 1. In this continuous seaweed roasting device, when the tow bar is moved to the air nozzle, the air nozzle blows air onto the tow bar below, which blows off the residual debris on the tow bar, keeping the tow bar clean and preventing the growth of a large number of microorganisms on the surface of the tow bar, thereby improving the final quality of the seaweed.

[0016] 2. In this continuous seaweed roasting device, by moving the horizontal plate back and forth inside the protective cover, the drive wheel that is in contact with the horizontal plate will rotate back and forth, which in turn will cause the tow bar to rotate back and forth. This back and forth rotation makes it easier for the tow bar to throw off seaweed fragments from the outer wall. Combined with the blowing action of the air nozzle, the cleanliness of the tow bar will be significantly improved.

[0017] 3. In this continuous seaweed roasting device, the horizontal plate drives multiple protrusions to slide over the rollers, which causes the receiving box to shake up and down, thereby allowing the seaweed fragments inside to be discharged efficiently from the discharge port. Since the baffle is connected to the receiving box through the connecting frame, the baffle will shake up and down with the receiving box, thereby shaking off the seaweed fragments on the inner wall, making it less likely for the seaweed fragments to generate a large number of microorganisms inside the baffle.

[0018] 4. In this continuous seaweed roasting device, during the blowing of seaweed fragments through the air nozzle, the seaweed fragments will fall into the receiving box, thus achieving effective collection in the receiving box, while the baffle can effectively intercept the seaweed fragments that splash upwards.

[0019] 5. In this continuous seaweed roasting device, the drive wheel will intermittently rotate forward and backward due to the action of the staggered upper and lower short plates, which in turn will cause the tow bar to intermittently rotate forward and backward. The tow bar will cause the seaweed above to move back and forth laterally, so that some parts of the seaweed are blocked by the tow bar for a long time, thereby making the seaweed heat more evenly and roasting effect better.

[0020] The parts of this device not described herein are the same as or can be implemented using existing technologies. This invention, through the setting of the air nozzle, can blow off the debris remaining on the tow bar, keeping the tow bar clean and preventing the growth of a large number of microorganisms on the surface of the tow bar, thereby improving the final quality of the seaweed. Furthermore, it can make the tow bar rotate back and forth, which can further improve the cleaning effect on the tow bar. Attached Figure Description

Detailed Implementation

[0024] 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.

[0025] Example: Reference Figures 1-8 As shown, a continuous seaweed roasting device includes a frame 1 for supporting the entire device. A protective cover 2 is fixedly installed on the frame 1. The protective cover 2 has openings on both sides. A heating device for roasting seaweed is installed inside the protective cover 2. The heating device is a heating lamp, heating wire, or hot air blower. The device also includes: a roller 3, which is rotatably installed inside the protective cover 2. A conveyor motor 6 for driving the roller 3 to rotate is fixedly installed on the protective cover 2. Two symmetrically arranged conveyor chains 4 are installed on the roller 3. Equally spaced drag bars 5 are rotatably installed between the two conveyor chains 4. The distance between two adjacent drag bars 5 is 1cm-5cm, preferably 1cm in this application. The drag bars 5 are used to support the seaweed. A nozzle 14 is fixedly installed at the bottom inside the protective cover 2. An air nozzle 15 facing the roller 3 is installed at the lower end of the nozzle 14. A drive unit is provided inside the protective cover 2. When the drag bar 5 moves below the air nozzle 15, the drive unit drives the drag bar 5 to rotate.

[0026] Specifically, when seaweed needs to be roasted, the seaweed is placed on the tow bar 5, and then the conveyor motor 6 is started. The conveyor motor 6 drives the conveyor chain 4 to run continuously through the roller 3. The conveyor chain 4 then continuously conveys the seaweed through the tow bar 5. While the seaweed is passing through the protective cover 2, the heating equipment continuously heats the seaweed to roast it. After roasting, the seaweed is discharged from the other end of the protective cover 2. When the tow bar 5 moves to the air nozzle 15, the air nozzle 15 blows air onto the tow bar 5 below, which blows off the remaining debris on the tow bar 5, keeping the tow bar 5 clean. The surface of the tow bar 5 is less likely to produce a large number of microorganisms, thereby improving the final quality of the seaweed. During this period, the drive unit drives the tow bar 5 to rotate, and the tow bar 5 actively throws off the seaweed debris adhering to the outer wall. The combination of the two will make the tow bar 5 cleaner and significantly reduce the microorganisms on the surface of the tow bar 5.

[0027] Of course, in other implementations, refer to Figures 3-6As shown, the drive unit includes a horizontal plate 16 installed on the inner wall of the protective cover 2. The horizontal plate 16 has two symmetrical sets, located on both sides of the conveying structure. A drive wheel 7 is fixedly installed at the end of the roller shaft 3. The horizontal plate 16 is used to drive the drive wheel 7 to rotate. The drive wheel 7 is made of rubber. When the roller shaft 3 moves to the position corresponding to the horizontal plate 16, the horizontal plate 16 will drive the drive wheel 7 to rotate. The horizontal plate 16 is slidably connected to the inner wall of the protective cover 2. A disc 17 is rotatably installed inside the protective cover 2 through a rotating shaft 19. A push rod 18 is rotatably installed on the shaft end face of the disc 17. The other end of the push rod 18 is rotatably connected to the outer wall of the horizontal plate 16. The disc 17, the push rod 18 and the horizontal plate 16 constitute a crank-slider mechanism. A drive motor 20 is fixedly installed inside the protective cover 2. The output shaft of the drive motor 20 is connected to the rotating shaft 19 through two meshing transmission gears 21.

[0028] Specifically, the drive motor 20 drives the rotating shaft 19 to rotate through two meshing transmission gears 21. The rotating shaft 19 drives the disc 17 to rotate. The disc 17 drives the horizontal plate 16 to move back and forth inside the protective cover 2 through the push rod 18 using the crank-slider principle. This causes the drive wheel 7, which is in contact with the horizontal plate 16, to rotate back and forth, which in turn causes the tow bar 5 to rotate back and forth. This back and forth rotation makes it easier for the tow bar 5 to shake off seaweed debris from the outer wall, significantly improving the cleanliness of the tow bar 5 and further reducing the microorganisms generated on the tow bar 5. Especially after the seaweed is brushed with oil, the debris is more likely to stick to the outer wall of the tow bar 5.

[0029] Of course, in other implementations, refer to Figures 3-7 As shown, the inner bottom of the protective cover 2 is equipped with a receiving box 11 with its opening facing the air nozzle 15. The receiving box 11 is used to collect the blown-down seaweed fragments. The bottom of the receiving box 11 is provided with a discharge port 12 for discharging the seaweed fragments. The upper end of the receiving box 11 is fixedly installed with a downward-facing baffle 13 via a connecting bracket 22. The baffle 13 easily intercepts the seaweed fragments that splash upwards. There is a gap between the baffle 13 and the receiving box 11. The continuously moving tow rod 5 is located in the gap, and the air nozzle 15 is located inside the baffle 13. The receiving box 11 is slidably connected to the inner wall of the protective cover 2. When the horizontal plate 16 moves back and forth, the receiving box 11 shakes up and down inside the protective cover 2. The outer wall of the receiving box 11 is fixedly connected to the limiting block 30. A spring 31 is installed between the limiting block 30 and the inner bottom of the protective cover 2. The bottom of the horizontal plate 16 is fixedly installed with a plurality of protrusions 28 arranged at equal intervals. The number of protrusions 28 is 3 to 10. In this application, the preferred number is 5. The outer wall of the receiving box 11 is rotatably installed with a roller 29. The roller 29 presses against the lower end surface of the horizontal plate 16.

[0030] During the blowing of seaweed fragments by the air nozzle 15, the seaweed fragments will fall into the receiving box 11, thus achieving effective collection by the receiving box 11, while the baffle 13 can effectively intercept the seaweed fragments that splash upwards. During the reciprocating horizontal movement of the horizontal plate 16, multiple protrusions 28 will slide over the rollers 29. The rollers 29 will move downward intermittently under the pressure of the multiple protrusions 28, thereby causing the receiving box 11 to move downward synchronously. The spring 31 can drive the receiving box 11 to move upward and reset. Thus, the multiple reciprocating horizontal movement of the protrusions 28 can make the receiving box 11 shake up and down, thereby allowing the seaweed fragments inside to be discharged efficiently from the discharge port 12. Since the baffle 13 is connected to the receiving box 11 through the connecting frame 22, the baffle 13 will shake up and down with the receiving box 11, thereby shaking off the seaweed fragments on the inner wall, making it less likely for the seaweed fragments to generate a large number of microorganisms inside the baffle 13.

[0031] Of course, in other implementations, refer to Figure 5 and Figure 6 As shown, a telescopic airbag 25 is installed inside the protective cover 2. An air intake pipe 27 and an exhaust pipe 26 are fixedly connected to each of the two telescopic airbags 25. A one-way valve is fixedly installed inside the air intake pipe 27 and the exhaust pipe 26, so that the air intake pipe 27 can only take in air, while the exhaust pipe 26 can only exhaust air. The end of the exhaust pipe 26 is fixedly connected to and communicates with the nozzle 14. A symmetrically arranged fixing plate 24 is fixedly connected inside the protective cover 2. Two symmetrically arranged pressure plates 23 are fixedly installed on the horizontal plate 16. The telescopic airbag 25 is fixedly installed between the fixing plate 24 and the pressure plate 23.

[0032] Specifically, during the reciprocating lateral movement of the horizontal plate 16, the pressure plate 23 will also reciprocate lateral movement. The pressure plate 23 will indirectly squeeze and stretch the telescopic airbag 25. When the telescopic airbag 25 is stretched, it will draw in air through the suction pipe 27, and when it is squeezed, it will blow air to the nozzle 14 through the exhaust pipe 26. The nozzle 14 can then blow air to the tow bar 5 through the air nozzle 15 at the bottom. In practice, if the air flow of the telescopic airbag 25 is insufficient, the nozzle 14 can be connected to an external air pump to supplement the air source.

[0033] Of course, in other implementations, refer to Figure 3 , Figure 4 as well as Figure 8 As shown, a strip plate 8 is fixedly installed inside the protective cover 2. Multiple upper short plates 9 and lower short plates 10 are fixedly connected to the strip plate 8. The upper short plates 9 and lower short plates 10 are located on the upper and lower sides of the drive wheel 7, respectively, and the upper short plates 9 and lower short plates 10 are staggered.

[0034] Specifically, as the tow bar 5 passes through the baking area, the drive wheel 7 at the end of the tow bar 5 will alternately slide over the upper short plate 9 and the lower short plate 10. The upper short plate 9 will cause the drive wheel 7 to rotate forward, while the lower short plate 10 will cause the drive wheel 7 to rotate in reverse. Thus, under the action of the staggered upper short plate 9 and lower short plate 10, the drive wheel 7 will intermittently rotate forward and reverse, which will cause the tow bar 5 to intermittently rotate forward and reverse. The tow bar 5 will cause the seaweed above to move back and forth laterally, so that the local part of the seaweed is blocked by the tow bar 5 for a long time, thereby making the seaweed heat more evenly and baking better.

[0035] Reference Figure 7 As shown, the inner bottom of the receiving box 11 is recessed towards the discharge port 12, making the receiving box 11 funnel-shaped, which can effectively improve the efficiency of the discharge port 12 in discharging seaweed fragments.

[0036] In this invention, when seaweed needs to be roasted, the seaweed is placed on the tow bar 5, and then the conveyor motor 6 is started. The conveyor motor 6 drives the conveyor chain 4 to run continuously through the roller 3. The conveyor chain 4 then continuously conveys the seaweed through the tow bar 5. While the seaweed is passing through the protective cover 2, the heating device continuously heats the seaweed to roast it. After roasting, the seaweed is discharged from the other end of the protective cover 2. When the tow bar 5 moves to the air nozzle 15, the air nozzle 15 blows down the remaining debris on the tow bar 5, keeping the tow bar 5 clean. The surface of the tow bar 5 is less likely to produce a large number of microorganisms, thereby improving the final quality of the seaweed. During this period, the drive motor 20 drives the rotating shaft 19 to rotate through two meshing transmission gears 21. The rotating shaft 19 drives the disc 17 to rotate. The disc 17 drives the horizontal plate 16 to move back and forth inside the protective cover 2 through the push rod 18 using the crank-slider principle. This causes the drive wheel 7, which is in contact with the horizontal plate 16, to rotate back and forth, which in turn causes the tow bar 5 to rotate back and forth. This back and forth rotation causes the tow bar 5 to throw off seaweed debris from the outer wall, keeping the tow bar 5 clean. The surface of the tow bar 5 is less likely to produce a large number of microorganisms, thus improving the final quality of the seaweed. During the blowing of seaweed fragments by the air nozzle 15, the seaweed fragments will fall into the receiving box 11, thus achieving effective collection by the receiving box 11, while the baffle 13 can effectively intercept the seaweed fragments that splash upwards. During the reciprocating horizontal movement of the horizontal plate 16, multiple protrusions 28 will slide over the rollers 29. The rollers 29 will move downward intermittently under the pressure of the multiple protrusions 28, thereby causing the receiving box 11 to move downward synchronously. The spring 31 can drive the receiving box 11 to move upward and reset. Thus, the multiple reciprocating horizontal movement of the protrusions 28 can make the receiving box 11 shake up and down, thereby allowing the seaweed fragments inside to be discharged efficiently from the discharge port 12. Since the baffle 13 is connected to the receiving box 11 through the connecting frame 22, the baffle 13 will shake up and down with the receiving box 11, thereby shaking off the seaweed fragments on the inner wall. During the reciprocating lateral movement of the horizontal plate 16, it also drives the pressure plate 23 to reciprocate lateral movement. The pressure plate 23 will indirectly squeeze and stretch the telescopic airbag 25. When the telescopic airbag 25 is stretched, it will draw in air through the air intake pipe 27. When it is squeezed, it will blow air to the nozzle 14 through the exhaust pipe 26. The nozzle 14 can then blow air to the tow bar 5 through the air nozzle 15 at the bottom. In practice, if the air flow of the telescopic airbag 25 is insufficient, the nozzle 14 can be connected to an external air pump to supplement the air source. As the tow bar 5 passes through the baking area, the drive wheel 7 at the end of the tow bar 5 will alternately slide over the upper short plate 9 and the lower short plate 10. The upper short plate 9 will cause the drive wheel 7 to rotate forward, while the lower short plate 10 will cause the drive wheel 7 to rotate in reverse. Thus, under the action of the staggered upper short plate 9 and lower short plate 10, the drive wheel 7 will intermittently rotate forward and reverse, which will cause the tow bar 5 to intermittently rotate forward and reverse. The tow bar 5 will cause the seaweed above to move back and forth laterally, so that the local part of the seaweed is blocked by the tow bar 5 for a long time, thereby making the seaweed heat more evenly and baking better.
