Description

Technical Field

[0001] This utility model relates to the field of meat roasting technology, and more specifically, to a high-power laser meat roasting device. Background Technology

[0002] Meat roasting, as a long-standing food processing method, is widely used in home cooking, the catering industry, and food industrial production. Its core requirement is to achieve a thoroughly cooked, dehydrated, and charred texture through energy input, while also stimulating the formation of flavor compounds in the meat. Currently, the mainstream meat roasting technologies in the industry are mainly divided into two categories: traditional open-flame roasting and modern electric heating roasting. Traditional open-flame roasting techniques primarily use charcoal or natural gas as energy sources, heating meat through the high-temperature flames and heat radiation generated by fuel combustion. The advantage of this technique is that the flames directly contact the surface of the meat, creating a caramelized layer and imparting a unique smoky flavor. However, the heating uniformity is extremely poor; areas with concentrated flames are prone to localized charring while the inside remains uncooked. Frequent manual turning of the meat is necessary, relying on the operator's experience and judgment, making it unsuitable for standardized mass production. Furthermore, it lacks sufficient safety and environmental friendliness. While electric heating roasting technology solves the pollution problem of open flames, it still suffers from low heating efficiency and slow speed. Additionally, the heat radiation has weak penetration, making it easy for large pieces of meat to remain raw on the inside and cooked on the outside. Utility Model Content

[0014] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0015] As attached Figure 1 To be continued Figure 5As shown, an embodiment of this utility model provides a high-power laser meat grilling device, including a grilling rack 1, a protective device 2, a rotating device 3, and an irradiation device 4. The protective device 2 is movably installed on the top of the grilling rack 1, the irradiation device 4 is slidably installed on the bottom of the protective device 2, and the rotating device 3 is disposed inside the grilling rack 1. like Figure 4 As shown, the protective device 2 includes a protective cover 21. Movable rods 22 are fixedly connected to both ends of both sides of the protective cover 21. Multiple slots 23 are opened on both sides of the lower end of the movable rods 22. Three sliding grooves 24 are opened on the top of the protective cover 21. A reciprocating screw 25 is rotatably installed in the middle of the top of the protective cover 21. Limiting rods 28 are fixedly connected to both sides of the top of the protective cover 21. The reciprocating screw 25 and the two limiting rods 28 are respectively located above the three sliding grooves 24. A moving motor 26 is fixedly connected to one side of the top of the protective cover 21. A belt drive component 27 is fixedly connected to the output end of the moving motor 26. One end of the belt drive component 27 is connected to the reciprocating screw 25.

[0016] like Figure 6 As shown, the irradiation device 4 includes a lampshade 41, a connecting frame 42 fixedly connected to the top of the lampshade 41, the connecting frame 42 being movably sleeved on the outer surface of the reciprocating screw 25 and the limiting rod 28, the connecting frame 42 being slidably installed inside the sliding groove 24, a plurality of lamp tubes 43 being fixedly connected inside the lampshade 41, a laser 44 being fixedly connected to the upper end of the lamp tubes 43, a beam expander lens 45 being fixedly connected to the lower end of the lamp tubes 43, a light-diffusing lens 46 being fixedly connected to the bottom of the lamp tubes 43, and a glass lamp plate 47 being fixedly connected to the bottom of the lampshade 41.

[0017] Specifically, the power of laser 44 is adjusted according to the type of food. The laser emitted by laser 44 passes through beam expander lens 45 and homogenizer lens 46. The beam expander lens 45 can be designed using traditional optical design to create a lens group with the functions of beam expansion and increasing the beam divergence angle. The main function of increasing the beam divergence angle is to enable the laser of this invention to illuminate a larger area. There are many solutions to this lens design structure, which belongs to the basic technology in the field of optics. The specific lens group design will not be given in this invention. Homogenizer lens 46 can homogenize the expanded laser beam, making the energy distribution of the laser beam more uniform.

[0018] Specifically, the moving motor 26 controls the rotation of the reciprocating screw 25 through the transmission of the belt drive 27, and limits the connecting frame 42 through the limiting rod 28, so that the connecting frame 42 slides inside the sliding groove 24, and controls the irradiation device 4 to reciprocate inside the protective cover 21 by the movement of the connecting frame 42 on the outer surface of the reciprocating screw 25.

[0019] like Figure 2As shown, the baking rack 1 includes a fixed frame 11, a support leg 13 is fixedly connected to the bottom of the fixed frame 11, a bottom frame 16 is fixedly connected to the bottom of the fixed frame 11, an oil collection tray 14 is movably sleeved on one side of the lower end of the fixed frame 11, a plurality of rotating holes 12 are opened on the side of the upper end of the fixed frame 11, and an adjustment device 15 is fixedly connected to both ends of both sides of the fixed frame 11.

[0020] Specifically, the oil collection tray 14 collects the waste generated during grilling, making it easier to clean the inside of the fixing rack 11.

[0021] like Figures 4-5 As shown, the adjusting device 15 includes a fixed sleeve 151. Both sides of the upper end of the fixed sleeve 151 are movably sleeved with locking rods 152. A ball bearing 153 is rotatably installed on the opposite side of the two locking rods 152. A locking spring 154 is fixedly connected to the side of the locking rod 152. The locking spring 154 is located between the locking rod 152 and the inner wall of the fixed sleeve 151.

[0022] Among them, the protective cover 21 is movably sleeved on the top of the fixed frame 11, the movable rod 22 is movably sleeved inside the fixed sleeve post 151, and the snap rod 152 is inserted into the inside of the snap groove 23, the upper and lower sides of the snap groove 23 are both inclined surfaces.

[0023] Specifically, when the protective cover 21 is pulled upward using the inclined surfaces on both sides of the slot 23, the movable rod 22 moves upward inside the fixed sleeve 151. The inclined surface of the slot 23 presses against the ball bearing 153, compressing the locking spring 154. The locking rod 152 retracts into the fixed sleeve 151, causing the movable rod 22 to rise inside the fixed sleeve 151. The height of the movable rod 22 can be adjusted through multiple slots 23. Similarly, when meat needs to be grilled using the irradiation device 4, the protective cover 21 is pressed down. The inclined surface of the slot 23 and the ball bearing 153 cause the movable rod 22 to descend inside the fixed sleeve 151. The reaction force of the locking spring 154 causes the locking rod 152 to engage with the upper end of the movable rod 22, keeping the protective cover 21 at the top of the fixed frame 11. The protective cover 21 is movable at the top of the fixed frame 11, facilitating the handling of the grilled meat.

[0024] like Figure 3 As shown, the rotating device 3 includes multiple rotating sleeves 33, which are rotatably mounted on one side of the upper end of the fixed frame 11. One end of the rotating sleeve 33 is fixedly connected to a transmission gear 34, and the other end of the rotating sleeve 33 is provided with a hexagonal groove 36. A rotating motor 31 is fixedly connected inside the bottom frame 16, and a drive gear 32 is fixedly connected to the output end of the rotating motor 31. A chain 35 is sleeved on the outer surface of the transmission gear 34 and the drive gear 32.

[0025] The rotating device 3 also includes a pin 37, one end of which is fixedly connected to a hexagonal prism 38. The hexagonal prism 38 is inserted into the interior of the hexagonal slot 36, and the pin 37 is rotatably installed inside the rotating hole 12.

[0026] Specifically, the rotating motor 31 controls the chain 35 through the drive gear 32. Through the meshing of the chain 35 and the transmission gear 34, the rotating sleeve 33 rotates at the upper end of the fixed frame 11, and through the pin 37, the meat is rotated, making the meat roast more evenly and improving the roasting effect.

[0027] In addition, the shape of the hexagonal groove 36 corresponds to the hexagonal prism 38. The operator skewers the meat on the outer surface of the needle 37, so that the needle 37 moves into the interior of the rotating hole 12, and inserts the hexagonal prism 38 into the interior of the hexagonal groove 36, thus realizing the assembly and disassembly of the needle 37.

[0028] The working process of this utility model is as follows: When in use, the operator pulls up the protective cover 21, and the movable rod 22 moves upward inside the fixed sleeve 151. The inclined surface of the slot 23 squeezes the ball 153, which compresses the snap-fit ​​spring 154. The snap-fit ​​rod 152 retracts into the fixed sleeve 151, and then the movable rod 22 rises inside the fixed sleeve 151. Through the reaction force of the snap-fit ​​spring 154, the snap-fit ​​rod 152 snaps into the slot 23 at the lower end of the movable rod 22, so that the protective device 2 is fixed on the top of the baking rack 1. The operator skewers the meat onto the outer surface of the skewer 37, causing the skewer 37 to move into the interior of the rotating hole 12. Then, the hexagonal prism 38 is inserted into the interior of the hexagonal slot 36. The rotating motor 31 controls the chain 35 through the drive gear 32. Through the meshing of the chain 35 and the drive gear 34, the rotating sleeve 33 rotates at the upper end of the fixed frame 11, and through the skewer 37, the meat is rotated, making the meat roast more evenly. Subsequently, the protective cover 21 is pressed down, and the movable rod 22 descends inside the fixed sleeve 151. Through the reaction force of the snap-fit ​​spring 154, the snap-fit ​​rod 152 snaps into the upper end of the movable rod 22, so that the protective cover 21 stays on the top of the fixed frame 11. The moving motor 26 controls the rotation of the reciprocating screw 25 through the transmission of the belt drive component 27, and limits the connecting frame 42 through the limiting rod 28, so that the connecting frame 42 slides inside the sliding groove 24. Through the movement of the connecting frame 42 on the outer surface of the reciprocating screw 25, the irradiation device 4 is controlled to reciprocate inside the protective cover 21 to achieve the roasting of meat.
