Description

Technical Field

[0001] This utility model relates to the technical field of pecan processing equipment, and in particular to a layered rack for low-temperature baking of pecans. Background Technology

[0002] Pecans, a type of nut rich in unsaturated fatty acids, protein, and various trace elements, have seen increasing market demand year by year. Consumers are placing higher demands on the taste (such as crispness) and nutrient retention of pecans. Low-temperature roasting (within a temperature range of 100-150℃) can minimize the oxidative loss of nutrients (such as vitamin E and unsaturated fatty acids) while avoiding the burnt odor caused by high temperatures, and has become the mainstream processing technique for pecans.

[0003] However, in existing technologies, when baking pecans in a traditional single-layer baking pan, the stacking of pecans results in a large difference in heating between the bottom and the top, which can easily lead to localized over-burning or undercooking. If a multi-layer baking pan is used, the fixed spacing between each layer and the strong sealing prevent the hot air from circulating fully, resulting in poor heat circulation and difficulty in ensuring even baking. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a layered wire rack for low-temperature baking of pecans.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a tiered rack for low-temperature baking of pecans, comprising a first frame, three sets of second frames arranged sequentially from bottom to top above the first frame, threaded cylinders being installed through the upper ends of the first frame and the three sets of second frames near the four corners, threaded rods being threadedly connected inside each set of threaded cylinders, and hexagonal seats being welded to the upper ends of each set of threaded rods, and hexagonal grooves being provided at the lower ends of the three sets of second frames near the four corners.

[0006] Preferably, the interior of the first frame and the three sets of second frames are all provided with honeycomb mesh panels, and the multiple sets of hexagonal seats are respectively inserted into the interior of the corresponding hexagonal slots.

[0007] Preferably, each set of honeycomb mesh panels has limit blocks installed at both ends, and each set of limit blocks has a cover plate snapped onto its upper end. The upper ends of the first frame and the three sets of second frames are provided with two sets of placement slots. The inner side walls of each set of placement slots are provided with elliptical grooves. Each set of limit blocks has elliptical blocks on both sides. The upper opening of each set of cover plates is provided with a rotating handle. Both ends of each set of rotating handles are fixedly installed with screws, and the teeth of the two sets of screws are opposite. The outer wall of each set of screws is threaded with a screw seat.

[0008] Preferably, multiple sets of the limiting blocks are respectively disposed inside the corresponding placement grooves, multiple sets of the elliptical blocks are respectively disposed inside the corresponding elliptical grooves, and multiple sets of the screws are threadedly connected to multiple sets of screw seats.

[0009] Preferably, the multiple sets of screws are rotatably installed inside the multiple sets of limiting blocks, and the two sets of screw seats are slidably installed inside the set of limiting blocks. One end of each of the two sets of elliptical blocks passes through both ends of the set of limiting blocks and is fixed to one end of the corresponding screw seat.

[0010] Preferably, concave seats are installed at the lower end of the first frame and near the four corners, and support legs are rotatably installed inside the four sets of concave seats.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, the fine-threaded connection between the threaded cylinder and the threaded rod, combined with the positioning and embedding of the hexagonal seat and the hexagonal slot, enables precise adjustment of the spacing between adjacent frames (frame 1 and frame 2, and between frame 2). Compared with traditional fixed spacing or snap-fit ​​adjustment structures, the adjustment accuracy is improved. The spacing between layers can be flexibly adjusted according to the baking quantity of pecans, the capacity of the oven / air fryer, and the intensity of hot air circulation, ensuring that each layer of pecans can fully contact the hot air and avoiding uneven heating caused by improper spacing, thus adapting to baking needs in different scenarios.

[0013] 2. In this utility model, the double fixing of threaded connection and hexagonal positioning: the fine thread connection of the threaded cylinder and the threaded rod has self-locking property. Combined with the embedded positioning of the hexagonal seat and the hexagonal groove, it can effectively prevent the frame from shifting or the interlayer spacing from changing due to vibration during the baking process. Compared with the traditional snap-on layered structure, the connection stability is improved, and the pecans are prevented from piling up due to frame shaking.

[0014] 3. In this utility model, with the cooperation of the limiting block, elliptical groove, elliptical block, rotating handle, screw and screw seat, the elliptical block can be inserted into or removed from the elliptical groove, the limiting block can be fixed inside the placement groove, and the honeycomb mesh panel can be fixed inside the corresponding first frame or three sets of second frames. Conversely, the honeycomb mesh panel can be removed from the corresponding first frame or three sets of second frames, which facilitates cleaning of the honeycomb mesh panel and the first or second frame.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a layered rack for low-temperature baking of pecans, including a first frame 1. Three sets of second frames 5 are arranged sequentially from bottom to top above the first frame 1. Threaded cylinders 4 are installed through the upper ends of the first frame 1 and the three sets of second frames 5 near the four corners. Threaded rods 6 are threadedly connected inside each set of threaded cylinders 4. Hexagonal seats 7 are welded to the upper end of each set of threaded rods 6. Hexagonal grooves 9 are opened at the lower ends of the three sets of second frames 5 near the four corners. Honeycomb mesh plates 8 are arranged inside the first frame 1 and the three sets of second frames 5. Multiple sets of hexagonal seats 7 are inserted into the corresponding hexagonal grooves 9.

[0023] The specific settings and functions of this embodiment are described below. Frame 1 serves as the basic load-bearing structure of the entire wire mesh frame. It is made of 304 food-grade stainless steel and is integrally stamped. The overall design is a rectangular frame. The outer contour size can be adapted to the inner size of mainstream ovens / air fryers. This ensures structural stability to support the weight of multiple layers of pecans while controlling the overall weight for easy handling. The inner side wall of the frame has an installation groove along the perimeter for embedding the honeycomb mesh plate 8. The inner wall of the installation groove is glued with a high-temperature resistant silicone sealing ring, which can enhance the fit between the honeycomb mesh plate 8 and the frame and prevent pecan crumbs from falling out of the gaps during baking.

[0024] The second frame 5 has the same structural dimensions as the first frame 1 and is made of the same 304 food-grade stainless steel. There are three sets of them, which are arranged in parallel from bottom to top in the vertical direction above the first frame 1 to form a "1+3" four-layer baking structure. The inner side wall of each set of the second frame 5 also has a mounting groove for installing the honeycomb mesh plate 8. The outer side wall of the frame is sprayed with a high-temperature resistant matte anti-scratch coating, which can reduce scratches during long-term use and avoid reflection affecting the temperature monitoring accuracy inside the oven.

[0025] The threaded cylinder 4 is made of food-grade 304 stainless steel and has a cylindrical structure. The inner wall is provided with precision fine threads. There are 16 sets of threaded cylinder 4 (one set at each of the four corners of frame 1 and one set at each of the four corners of frame 5). All of them are vertically fixed to the upper surface of the corresponding frame by laser welding process, and the welded parts are polished to prevent residual welding slag from scratching hands or contaminating pecans.

[0026] The threaded rod 6 is used in conjunction with the threaded cylinder 4. Both are made of 304 food-grade stainless steel. The outer wall is machined with fine threads that match the inner wall of the threaded cylinder 4 to ensure the stability and smoothness of the threaded connection. The hexagonal seat 7 is a regular hexagonal structure and is connected to the upper end of the threaded rod 6 through an integrated forging process. A 0.3cm diameter anti-slip groove is opened at the center of the upper surface of the hexagonal seat 7 to increase the friction during operation.

[0027] The hexagonal slots 9 are located on the lower end face of each group of No. 2 frame 5 near the four corners, and are perfectly matched with the external dimensions of the hexagonal base 7. The slots are also lined with high-temperature resistant silicone pads. When the threaded rod 6 and the threaded cylinder 4 are connected by threads, the hexagonal base 7 can be fully embedded in the corresponding hexagonal slots 9. The silicone pads can fill the tiny gaps between the two, enhance the connection stability, avoid the abnormal noise caused by direct metal-to-metal contact, and also play a buffering role to reduce the vibration transmission of the frame during baking.

[0028] The honeycomb mesh panel 8 is woven from 304 food-grade stainless steel wire. The mesh is a regular hexagonal honeycomb structure with an inscribed circle diameter of 1.8cm, which is precisely matched to the particle size of pecans (1.5-2.5cm in diameter). This effectively prevents small pecan particles from falling off while ensuring smooth hot air penetration. The weaving density reaches 1.2 mesh holes per square centimeter, combining good load-bearing strength (a single mesh panel can bear ≤500g of pecans) and thermal conductivity. High-temperature resistant silicone strips are pasted on the outer edge, which can fit tightly with the mounting grooves of frame 1 and frame 5, further improving sealing and installation stability.

[0029] Example 2: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, each set of honeycomb mesh panels 8 has limit blocks 10 installed at both ends, and each set of limit blocks 10 has a cover plate 11 snapped onto its upper end. The upper ends of the first frame 1 and the three sets of second frames 5 each have two sets of placement slots 12. Each set of placement slots 12 has elliptical grooves 13 on both sides of its inner sidewalls. Each set of limit blocks 10 has elliptical blocks 14 on both sides. Each set of cover plates 11 has a rotating handle 15 at its upper opening. Each set of rotating handles 15 has screws 16 fixedly installed at both ends, with the teeth of the two sets of screws 16 being opposite. The outer wall of 6 is threaded with screw seats 17. Multiple sets of limiting blocks 10 are respectively set inside the corresponding placement grooves 12. Multiple sets of elliptical blocks 14 are respectively set inside the corresponding elliptical grooves 13. Multiple sets of screws 16 are threadedly connected to multiple sets of screw seats 17. Multiple sets of screws 16 are rotatably installed inside multiple sets of limiting blocks 10. Every two sets of screw seats 17 are slidably installed inside a set of limiting blocks 10. One end of every two sets of elliptical blocks 14 passes through both ends of a set of limiting blocks 10 and is fixed to one end of the corresponding screw seat 17.

[0030] The overall effect of this embodiment is that by rotating the handle 15, the handle 15 drives the two sets of screws 16 to rotate inside the limiting block 10. At the same time, the two sets of screws 16 rotate threadedly inside the two sets of screw seats 17, causing the two sets of screw seats 17 to move in opposite directions inside the limiting block 10. The two sets of screw seats 17 also drive the elliptical block 14 fixed with them to move, so that the elliptical block 14 is inserted into or removed from the elliptical groove 13. This can fix the limiting block 10 inside the placement groove 12, making it convenient to fix the honeycomb mesh plate 8 inside the corresponding first frame 1 or three sets of second frames 5. In other words, it can remove the honeycomb mesh plate 8 from the corresponding first frame 1 or three sets of second frames 5, making it convenient to clean the honeycomb mesh plate 8 and the first frame 1 or second frame 5.

[0031] The concave seat 2 is made of high-temperature resistant PP material and has an overall "U" shaped structure. There are four sets in total, which are fixed to the lower end face of the first frame 1 near the four corners by bolts. The inner wall is smooth to ensure the smooth rotation of the support leg 3.

[0032] The support leg 3 is made of 304 food-grade stainless steel and is covered with a high-temperature resistant silicone sleeve. The surface of the silicone sleeve has a diamond-shaped anti-slip texture, which not only enhances the friction between the support leg 3 and the bottom of the oven / air fryer inner pot, but also prevents the metal from directly contacting the inner pot and causing scratches. This allows the support leg 3 to rotate freely within the concave base 2 within a range of 0°-90°, enabling the support leg 3 to be unfolded and stored.

[0033] The usage and working principle of this device: Support and fixation stage: unfold the support leg 3 inside the concave seat 2 at the bottom of frame 1. The silicone anti-slip sleeve on the surface of the support leg 3 contacts the bottom of the oven / air fryer inner pot. Through friction and the structural limitation of the concave seat 2, the wire rack is placed stably as a whole, avoiding displacement during baking.

[0034] Height adjustment and assembly stage: According to the pecan baking volume and equipment capacity, rotate the threaded rod 6 and use its fine thread engagement with the threaded cylinder 4 to adjust the spacing between frame 1 and frame 2, and between adjacent frames 5; at the same time, the hexagonal seat 7 at the upper end of the threaded rod 6 is embedded in the hexagonal groove 9 of the corresponding frame 5. Through the dual action of thread self-locking and hexagonal positioning, the interlayer spacing is fixed to form a stable four-layer baking space.

[0035] Baking and Hot Air Circulation Stage: Pecans are evenly spread on the honeycomb mesh plate 8 within frames 1 and 5 (single layer load ≤ 500g). The honeycomb mesh plate 8 has 1.8cm inscribed hexagonal mesh holes, which both intercept the pecans to prevent them from falling and ensure hot air penetration. During low-temperature baking (100-150℃), hot air circulates freely in the adjustable interlayer spacing, and fully contacts the pecans through the honeycomb mesh plate 8, forming an efficient heat circulation and ensuring that each layer of pecans is heated evenly.

[0036] Storage stage: After baking, unscrew the threaded rod 6 to disassemble each frame, fold the support leg 3 to 0° (fitting the bottom of frame 1), and then stack the frame and the wire mesh to reduce storage space occupation.

[0037] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
