[0061] The upper end of the discharging bin 41 is provided with a dehumidifying fan 43, which is in communication connection with the internal cavity thereof.

[0062] The core part of the device is the frying drum 2, which is connected to the base 1 as a whole to ensure its stability. The base 1 contains a support frame 11 and a driving mechanism 12. The support frame 11 serves to support and fix the frying drum 2, while allowing it to rotate freely so that the material can be fully turned over during frying, ensuring uniform heating. The driving mechanism 12 provides power through a driving motor 125, enabling the frying drum to rotate along its axis, thereby achieving effective frying of the material.

[0063] The feeding mechanism 3 is equipped with a burner 33, with the flame jet located inside the frying drum 2. This design ensures that heat is directly applied to the iron sand and material, promoting rapid heating and uniform frying of the material. The iron sand inside the frying drum 2 not only serves to heat, but also helps the material to turn over in the drum through its own movement, enhancing the frying effect. This combination of physical and thermal energy is the key to improving the frying efficiency of the device.

[0064] The frying drum 2 is composed of an outer cylinder 21 and an inner cylinder 22. The outer cylinder surface is equipped with multiple rolling rings 23, which are connected to the support frame 11, helping to maintain the stability of the drum and reduce friction. The design of the sieve holes 26, sand return holes 27 and interlayer allows the iron sand to flow freely between the outer cylinder 21 and the inner cylinder 22. The sieve holes 26 and sand return holes 27 of the inner cylinder 22 are designed reasonably, which can effectively control the flow of iron sand. The aperture of the sieve holes 26 is designed to be smaller than the particle size of the material, ensuring that the fried material will not fall off, while the iron sand can return smoothly. This design not only optimizes the efficiency of the use of iron sand, but also ensures the integrity of the material, which helps to improve the quality of the final product.

[0065] The design of the dispersed material baffle group 28 can further disperse the material in the inner cylinder. These baffles are distributed in a spiral shape, which can guide the material to form different flow paths, increase the collision and mixing frequency between the materials, and thus promote the uniformity and effect of frying. The scientific design ensures that every part of the material can fully contact the heat source and achieve the desired frying effect.

[0066] The combination of the support frame 11 and the limiting roller 112 enables the frying drum 2 to remain stable during rotation, preventing tilting or displacement. This design not only enhances the safety of the device, but also prolongs the service life of the device. The limiting roller provides necessary support and limitation, ensuring smooth and safe operation.

[0067] The design of the driving mechanism 12 adopts multiple gear linkages, making power transmission more efficient. The driving gear 121 is connected to the first intermediate gear 122 through a chain, forming a complete power transmission link. Through the precise cooperation between the gears, the rotation speed of the frying drum 2 is stabilized, thereby ensuring the uniformity of material frying.

[0068] The design of the feeding mechanism 3 and the discharging mechanism 4 ensures the continuous feeding and discharging of the material. The feeding bin 31 and the discharging bin 41 are designed in a cylindrical shape, allowing the material to flow smoothly into the roasting drum 2 under the action of gravity. At the same time, the dehumidifying fan 43 can effectively remove excess moisture, preventing the roasting effect from being reduced due to moisture during the roasting process. This design further enhances the overall functionality and efficiency of the equipment.

[0069] Working principle: The material is stored in the hopper 321 and automatically enters the roasting drum 2 through the feeding pipe 322 under the action of the feeding screw blade 323. The iron sand is prepared in advance in the roasting drum 2 and is driven by the inner cylinder spiral blade 25 from the end close to the feeding mechanism 3 to the end close to the discharging mechanism 4. Due to the design of the sieve hole 26 and the sand return port 27, the iron sand will fall into the interlayer between the outer cylinder 21 and the inner cylinder 22 from the sieve hole 26 and return to the end close to the feeding mechanism 3 under the action of the reverse outer cylinder spiral blade 24 and return to the inner cylinder 22 from the sand return port 27. The design of the burner 33 will heat the iron sand, and as the material and iron sand move in the roasting drum 2, the material will be stirred and roasted, and the roasted material will be automatically discharged from the discharge port 42 and transported to the next link by the discharge conveyor belt 5. The design of the dispersed material distribution baffle group 28 can further disperse the material during the roasting process and mix it evenly with the iron sand, improving the roasting effect. The design of the dehumidifying fan 43 is to remove the water vapor that may exist.

[0070] Among them, the material is stored in the hopper 321 or automatically fed into the hopper 321 by automatic equipment, and automatically enters the roasting drum 2 through the feeding pipe 322 under the action of the feeding screw blade 323. This process embodies the automation feature of the device, reduces manual operation, and improves production efficiency. The material has been accurately controlled when entering the roasting drum 2, ensuring the consistency of continuous feeding and the stability of the roasting process.

[0071] The iron sand added in advance in the roasting drum 2 not only plays a heating role, but also has a good stirring effect during the roasting process. The high specific gravity and good thermal conductivity of the iron sand enable it to quickly absorb the heat provided by the burner 33 and uniformly transfer it to the material. This heat transfer is very critical and can effectively reduce the risk of local overheating or coking of the material during the roasting process.

[0072] The existence of the screen holes 26 and the sand return ports 27 is an effective design for iron sand recycling. The iron sand enters the interlayer between the outer cylinder 21 and the inner cylinder 22 through the screen holes 26, and this process ensures the continuous recycling of the iron sand during the roasting process. As the inner cylinder 22 rotates, the iron sand is heated and constantly turned over, ensuring that every grain of iron sand can effectively participate in the roasting. Such a design not only improves the efficiency of resource utilization, but also reduces material loss.

[0073] The design of the dispersed distribution baffle group 28 ensures that the material can be further dispersed when flowing on the inner cylinder spiral blade 25, increasing the contact area between the materials. This not only helps to improve the roasting effect, but also avoids the phenomenon of material clumping during roasting. By constantly changing the flow path of the material, the arrangement of the baffle group can effectively improve the mixing degree between the material and the iron sand, making the heating more uniform.

[0074] The dehumidification fan 43 plays a crucial role in the design of the discharge bin 41. During the roasting process, especially for some water-containing materials, too much moisture may be left in the product, affecting the quality of the final product. The dehumidification fan can effectively remove the water vapor generated during the roasting process, ensuring the dryness of the material when discharging. This design allows the equipment to operate stably in a high-humidity environment, improving its adaptability.

[0075] The full-automatic snack roasting device realizes efficient automatic production through the coordinated work of various components. Whether it is feeding, roasting, discharging or dehumidification, the entire process is precisely monitored by the control system, ensuring the stability and efficiency of production. This highly automated design allows the equipment to effectively reduce labor costs in large-scale production, while improving product consistency and quality.
