[0002] With the improvement of people's living standards, the market demand for nuts, as a nutritious snack, has been increasing year by year, and the nut processing industry has also ushered in rapid development. In the nut processing process, drying is a key step to ensure nut quality and extend shelf life, and its efficiency and effectiveness directly affect the production benefits and product competitiveness of enterprises.

[0003] Most commercially available nut roasting ovens use a single-layer or multi-layer fixed placement structure. Since the nuts are in a static state during the drying process, they can only rely on hot air to pass over their surface for heat transfer, resulting in uneven heating of the nuts both inside and outside. In view of the above reasons, this application proposes a multi-layer automatic nut rotating roasting oven to improve drying efficiency. Summary of the Invention

[0038] Example

[0039] As shown in Figures 1-5, this utility model proposes a multi-layer automatic nut rotating baking box for improving drying efficiency, including a casing 1. The front of the casing 1 is provided with two inspection doors 2. The bottom of the casing 1 is fixedly provided with four support legs arranged in a rectangular pattern. Two drying boxes 3 for placing nuts are movably arranged inside the casing 1. Ventilation holes 5 are provided on the top and bottom inner walls of the drying boxes 3. Multiple air outlet slots 6 are provided on both sides of the drying boxes 3. The front of the drying boxes 3 is provided with a material door 4 for filling and removing materials. The drying boxes 3 are provided with a material feeding vibration structure 8 for improving the drying speed. The two sides of the two drying boxes 3 are provided with a rotating shaft 7 for driving the drying boxes 3 to rotate. The rotating shaft 7 on one side of the two drying boxes 3 passes through the casing 1. One end of one of the rotating shafts 7 is fixedly provided with a drive motor 10. The arrangement of the drive motor 10 and the rotating shaft 7 enables the drying boxes 3 to rotate, so that the materials in the drying boxes 3 are in motion, increasing the contact area between the materials and the hot air. Both rotating shafts 7 are fixedly provided with pulleys 11, and the same belt is fitted on the two pulleys 11.

[0040] The material-dispensing vibration structure 8 includes a screen plate 801 for vibrating the material and a material-dispensing motor 802 for driving it. Two material-dispensing plates 804 are mounted on the output shaft of the motor 802. Multiple material-dispensing teeth are fixed to the bottom of each of the two plates 804. The arrangement of the material-dispensing plates 804 and the teeth prevents material from accumulating and clumping, thus avoiding uneven drying. The teeth are made of silicone. A rotating rod 807 is located below the screen plate 801, and a triangular cam 809 is fixed to the rod 807. The protrusion of the triangular cam 809 intermittently contacts the bottom of the screen plate 801. Combined with a spring, this causes the screen plate 801 to vibrate, thereby tumbling the material above the screen plate 801. A bevel gear 803 is fixedly mounted on the output shaft of machine 802. A bevel gear 805 is mounted on one side of bevel gear 803. Bevel gear 803 and bevel gear 805 mesh and drive each other. A crossbar 806 is fixedly mounted on one side of bevel gear 805. Pulleys 808 are fixedly mounted on both crossbar 806 and rotating rod 807. The same belt is fitted on both pulleys 808. The sieve plate 801 and the drying box 3 are movably connected. Two sliding grooves are provided on both sides of the inner wall of the drying box 3. Two sliders 8010 are fixedly mounted on both sides of the sieve plate 801. A sliding rod 8011 is movably mounted in the center of the slider 8010. The sliding rod 8011 is fixedly connected to the sliding groove. A spring is fitted on the sliding rod 8011.

[0041] The machine casing 1 is equipped with a drying structure 9, which includes two air boxes 901. The two air boxes 901 are located above and below the drying box 3, respectively. The same air guide pipe 902 is fixed on one side of the two air boxes 901. A heating box 903 is fixed on one side of the air guide pipe 902. A fan 904 is located on one side of the heating box 903. The two air boxes 901 are located on the upper and lower sides of the drying box 3. The upper air box 901 blows air downwards, and the lower air box 901 blows air upwards, forming a hot air flow that is opposed from top to bottom, which can enhance the heat exchange efficiency and shorten the drying time.

[0042] In this embodiment, when drying the materials, the materials are first filled into the drying box 3. Then, the heating box 903, fan 904, drive motor 10, and feeding motor 802 are started in sequence. Drive motor 10 drives rotating shaft 7, which in turn drives one of the pulleys 11 to rotate the lower rotating shaft 7. Both rotating shafts 7 simultaneously drive the drying box 3. The rotation of the drying box 3 keeps the materials inside in motion, increasing the contact area between each nut and the hot air. Feeding motor 802 drives bevel gear 803 and feeding plate 804. Feeding plate 804 gently moves the nuts with feeding teeth to prevent them from clumping together. When the drying box 3 is tilted to an inclined angle, the feeding teeth insert into the nut pile and rotate to shake the nuts. The nuts are loosened, allowing each nut's surface to be fully exposed to hot air. Bevel gear 803 drives bevel gear 805, causing two pulleys 808 to rotate. The lower pulley 808 drives a rotating rod 807, which in turn drives a triangular cam 809. The triangular cam 809 contacts the sieve plate 801, causing it to vibrate. The nuts bounce slightly on the sieve plate 801 under this vibration, and this, combined with the tumbling action, creates a dual dynamic effect. A fan 904 directs air into a heating chamber 903, which heats the air and then directs it into two air boxes 901. These two air boxes 901 blow hot air towards the same drying box 3, creating opposing hot airflows that enhance heat exchange efficiency and shorten drying time.

[0043] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
