Description

Technical Field

[0001] The present invention relates to the technical field of drying equipment, and in particular to fully automatic roasting equipment for roasted seeds and nuts. Background Art

[0002] Traditional drum-type roasting machines consist of a rotating drum, open at one end and closed at the other. Spiral blades welded inside the drum heat the drum, drying and dehumidifying the material poured into it. The drum is fed and discharged from one end, so traditional roasting machines control the position of the material by controlling the drum's forward and reverse rotation. For example, forward rotation stirs the material, while reverse rotation discharges the material with the spiral blades. This conflicting feeding and discharging processes prevent continuous production.

[0003] In traditional drum-type roasting machines, the main function of the spiral blades is to guide the discharge of materials during discharge. The tumbling of materials in the drum is driven by the rotation of the drum itself. The drum is only open at one end, so there are problems such as low roasting efficiency and difficulty in discharging hot and humid air. Summary of the Invention

[0004] In view of the above-mentioned technical deficiencies, the purpose of the present invention is to provide a fully automatic frying equipment for roasted nuts and seeds, which can achieve continuous production while improving the uniformity of frying by designing two turning components.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solution: The present invention provides a fully automatic roasting device for roasted nuts, comprising: A frying cylinder, which is rotatably mounted on a frame, and has a feed port at one end and a discharge port at the other end; A heating component is provided on the frame and is used to heat the stir-fry tube; A feeding bin is used to add materials into the frying cylinder, and a solenoid valve is provided at the discharge end of the feeding bin; The central shaft is rotatably mounted on the frame and coincides with the axis of the stir-frying cylinder; Two turning components are arranged on the central axis and are used to turn the materials in the frying cylinder; The material turning assembly includes a sleeve sleeved on the central axis and a spiral material shifting piece fixed on the sleeve, and the sleeve has the freedom to rotate on the central axis and move along the central axis.

[0006] Preferably, the frying cylinder is horizontal, and both ends of the frying cylinder are provided with tapered closing parts, and the feed port and the discharge port are respectively located at the open ends of the two closing parts.

[0007] Preferably, the material-picking piece includes a constant-diameter section that cooperates with the inner wall of the frying cylinder and a variable-diameter section that cooperates with the inner wall of the closing portion.

[0008] Preferably, a plurality of material-diverting plates are provided on the outer edge of the material-diverting piece. When the sleeve rotates, the material-diverting plates and the material-diverting pieces rotate around the central axis and turn over the material in the frying cylinder.

[0009] Preferably, one end of the sleeve close to the center of the frying tube is spirally shaped. When the sleeves in the two turning assemblies approach each other along the central axis and spirally intertwine, the two equal-diameter sections spirally intertwine, and the variable-diameter section separates from the closing portion.

[0010] Preferably, two annular frames are fixed on the frame, and two annular rings are fixed on the frying cylinder, and the two annular rings are rotatably mounted on the two annular frames respectively through a plurality of guide wheels.

[0011] Preferably, a motor 1 is fixed on the frame, a gear 1 is fixed on one of the annular rings, and a gear 2 meshing with the gear 1 is fixed on the output shaft of the motor 1.

[0012] Preferably, the frame is provided with a turning drive mechanism, comprising: Motor 2, fixed on the frame; A spline sleeve is sleeved on the central shaft and fixedly connected to the sleeve; Gear three is sleeved on the spline sleeve and is driven by a key with the spline sleeve. The output end of the motor two is provided with a transmission box. The gear three is arranged in the transmission box and is driven to rotate by the motor two.

[0013] Preferably, a telescopic guide rod and an electric push rod parallel to the central axis are fixed on the frame, a collar is rotatably mounted on the sleeve, and the movable ends of the telescopic guide rod and the electric push rod are fixedly connected to the collar.

[0014] Preferably, a weighing device for detecting the weight of the material in the feed bin is provided below the feed bin.

[0015] The beneficial effects of the present invention are: The frying cylinder designed by the present invention has a feed port and a discharge port, which form a smooth exhaust channel in the frying cylinder, making it easier to discharge the hot and humid air generated during frying, thereby improving the frying efficiency; the present invention designs two turning components, which can independently rotate and move along the central axis, so that the material plucking piece and the inner wall of the frying cylinder have multiple matching relationships. When the two turning components move toward the center of the frying cylinder and spirally staggered, the material plucking piece is away from the feed port and the discharge port. At this time, the forward and reverse rotation of the frying cylinder will not cause the material to be discharged. The material plucking piece can rotate forward or reversely and rotate at the same speed or at a different speed as the frying cylinder, so that the material can be actively plucking. While the frying cylinder drives the material to turn, the material plucking piece can drive the material to reciprocate axially in the frying cylinder, which greatly enriches the turning form of the material, improves the stirring efficiency, makes the material heated more evenly, and better dries the material; The two turning components designed in the present invention can first cooperate to transport the material toward the discharge port, and then allow the turning component near one end of the discharge port to continue to discharge the material. At this time, the feeding bin can feed the material into the frying cylinder through the feed port. The turning component near one end of the feed port rotates to prevent the newly entered material from mixing with the fried material, thereby realizing discharging and feeding at the same time, thereby improving processing efficiency.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1: like Figures 1 to 8 As shown, the first embodiment of the present invention provides a fully automatic roasting device for roasted nuts, comprising a roasting cylinder 1, a heating component 5, a feeding bin 6, a central shaft 8 and two turning components. The roasting cylinder 1 is rotatably mounted on the frame 2 via a slewing bearing, and its axis is arranged horizontally. One end of the roasting cylinder 1 is a feed port 3, and the other end is a discharge port 4, forming a smooth axial channel. The feed port 3 and the discharge port 4 allow air to flow freely. Compared with the traditional single-end open design, the air flow channel of the present invention forms natural convection due to the openings at both ends, which can more quickly discharge the hot and humid gases generated by the heated materials, reduce the absorption of moisture by the materials, and prevent the materials from getting damp or overcooked, thereby improving the uniformity and efficiency of roasting.

[0028] The heating assembly 5 is fixed to the outer wall of the stir-frying cylinder 1 and uses an electric heating tube to directly and evenly heat the outer wall of the stir-frying cylinder 1. Heat is transferred through the cylinder wall to the interior of the material, achieving drying and dehumidification. The feed bin 6 is located next to the discharge port 4 of the stir-frying cylinder 1. The feed bin 6 is fixed by a bracket, and a weighing device 25 is installed on the top of the bracket. The weighing device 25 is a conventional weighing and metering device that calculates the weight of the material in the feed bin 6. The discharge pipe of the feed bin 6 is equipped with a solenoid valve 7 for precise control of material addition. The outlet of the discharge pipe is aligned with the feed port 3 of the stir-frying cylinder 1. When the solenoid valve 7 is opened, the material in the feed bin 6 is added to the stir-frying cylinder 1 through the discharge pipe and the feed port 3.

[0029] like Figure 6As shown, the ends of the central shaft 8 are rotatably mounted on the frame 2 via bearing blocks and are located along the axis of the stir-frying drum 1. Two material turning assemblies are mounted on the central shaft 8, each comprising a sleeve 9 that fits over the central shaft 8 and a spirally shaped material shifting piece 10 secured to the sleeve 9. The sleeve 9 can rotate about the central shaft 8 and slide axially along the central shaft 8, providing both rotational and translatory freedom. The spiral shape of the material shifting piece 10 is designed to conform to the inner wall of the stir-frying drum 1. A clearance exists between the outer edge of the material shifting piece 10 and the inner wall of the stir-frying drum 1, preventing the material shifting piece 10 from scraping against the inner wall of the stir-frying drum 1 while still allowing the material on the inner wall to be moved.

[0030] As the cooking drum 1 rotates on the frame 2, the material tumbles inside the cooking drum 1. At this time, the sleeve 9 also rotates, and the material-prying piece 10 rotates about the central axis 8, driving the material to move within the cooking drum 1. As the sleeve 9 moves along the central axis 8, it changes the position of the material-prying piece 10, driving the material to move.

[0031] In this embodiment, the rotation of the two sleeves 9 can play a role in limiting the position of the material. Since the two material-picking pieces 10 are spiral-shaped, they can play a role similar to that of a screw conveyor. By rotating the two sleeves 9 in opposite directions, the two material-picking pieces 10 can simultaneously convey the material to the middle of the frying cylinder 1, thereby preventing the material from rolling out of the frying cylinder 1 during the frying process. Under the action of the material-picking pieces 10, the material reciprocates back and forth along the axial direction of the frying cylinder 1, and cooperates with the rotation of the frying cylinder 1 itself to achieve multi-dimensional frying, so that the material is heated evenly and the efficiency is improved. The present invention achieves high-efficiency flipping and improves the exhaust efficiency of hot and humid air through the above-mentioned arrangement, avoiding the airflow blockage problem and insufficient flipping problem caused by the single-end design of the transmission.

[0032] Example 2: like Figures 6 to 8 As shown, based on the first embodiment, this embodiment features tapered openings 11 at both ends of the stir-fry cylinder 1. The feed port 3 is located at the open end of one of the openings 11, while the discharge port 4 is located at the open end of the other opening 11. The tapered openings 11 facilitate smooth entry of material from the feed port 3 and facilitate its collection toward the center. This prevents material from rolling out during stir-frying, thereby increasing the weight of material that can be stir-fried in a single batch.

[0033] Correspondingly, the spiral-shaped prying piece 10 is divided into a constant-diameter section 101, which mates with the straight inner wall of the stir-frying tube 1, and a variable-diameter section 102, which mates with the tapered inner wall of the closing end 11. The constant-diameter section 101 has a constant spiral radius, matching the straight inner wall of the stir-frying tube 1 and ensuring stable turning. The variable-diameter section 102 has a gradually decreasing radius, adapting to the tapered curve of the closing end 11, ensuring a good clearance with the tube wall at all locations.

[0034] like Figure 6As shown, in the initial state, the prying pieces 10 in the two turning components respectively cooperate with the inner cavities on both sides of the frying tube 1, maintain a small gap with the straight tube section and the closing part 11, and the rotation of the two turning components will not interfere with each other, so that the two prying pieces 10 can rotate in the same direction or opposite directions.

[0035] like Figure 7 As shown, as sleeve 9 moves along central axis 8, the distance between the material-dispensing disc 10 of the variable diameter section 102 and the inner wall of the closing portion 11 is adjusted. As the two turning assemblies approach each other through movement and rotation, their spiral-shaped material-dispensing discs 10 partially intersect, moving them away from the feed inlet 3 and the discharge port 4, respectively. Because the height of the closing portion 11 gradually increases from the inside out, and the variable diameter section 102 of the material-dispensing disc 10 is spaced a certain distance from the closing portion 11, the gap between the variable diameter section 102 and the inner wall of the corresponding closing portion 11 is greatly increased. Therefore, regardless of whether the cooking drum 1 is rotating forward or backward, the material is not pushed out of the cooking drum 1. This allows the material-dispensing disc 10 and the cooking drum 1 to rotate freely in forward, reverse, or at variable speeds, significantly enriching the material's turning trajectory and improving cooking uniformity.

[0036] A plurality of stripper plates 12 are fixed to the outer edge of the stripper plate 10. These small plate-like structures protrude perpendicularly from the surface of the stripper plate 10 along the axis 8. When the sleeve 9 rotates, the stripper plates 12 and the stripper plates 10 rotate together around the axis 8, forming a multi-layer stirring effect, which can more effectively break up agglomerated materials and increase the stirring depth and height of the materials.

[0037] Because the two turning assemblies need to be staggered in a spiral pattern, to prevent interference between the sleeves 9 on the central axis 8, the portion of the sleeve 9 near the center of the stir-frying cylinder 1 is designed to be spiral. When the two turning assemblies are driven toward each other by the moving mechanism, the two sleeves 9 can rotate and slide on the central axis 8, forming a spiral stagger. At this time, the constant diameter sections 101 overlap and stagger, and the variable diameter section 102 is separated from the closing portion 11. In this staggered state, the spacing between the constant diameter sections 101 of the two diverter plates 10 is reduced, and the distance between the diverter plates 12 at different spiral positions is shortened, thereby enhancing the turning effect on the material.

[0038] Example 3: On the basis of the second embodiment, the present invention specifically designs a driving mechanism for driving the frying cylinder 1 to rotate and the sleeve 9 to rotate and move.

[0039] like Figure 2 and Figure 3As shown, two fixed annular frames 13 are mounted on the frame 2, and two corresponding annular rings 14 are fixed to the outside of the stir-frying cylinder 1. The annular frames 13 and annular rings 14 are connected in a rolling manner via multiple guide wheels 15, forming a stable support that allows the stir-frying cylinder 1 to rotate smoothly without deviation. A motor 16 is fixed to the frame 2 to drive the stir-frying cylinder 1. Gear 1 17 is fixed to one of the annular rings 14, and Gear 2 18 is mounted on the output shaft of Motor 16, meshing with Gear 1 17. Both Gears 17 and 18 are bevel gears. Through this bevel gear transmission, Motor 16 can precisely control the rotation speed of the stir-frying cylinder 1.

[0040] like Figure 4 and Figure 5 As shown, a motor 2 19 is fixed on the frame 2, and the output end of the motor 2 19 is connected to the spline sleeve 20 through a transmission box 21. The spline sleeve 20 is mounted on the central shaft 8 and fixedly connected to the sleeve 9. A gear driven by the motor 2 19 is set in the transmission box 21. The gear is mounted on the spline sleeve 20 and is transmitted to the spline sleeve 20 through a keyway structure, thereby transmitting the rotational force to the spline sleeve 20 and the sleeve 9, thereby realizing the independent rotation of the material turning assembly. At the same time, a telescopic guide rod 22 and an electric push rod 23 parallel to the central shaft 8 are installed on the frame 2, and a rotatable collar 24 is installed on the sleeve 9. The movable end of the electric push rod 23 and the movable end of the telescopic guide rod 22 are both fixedly connected to the collar 24. The collar 24 is driven axially by the telescopic movement of the electric push rod 23, thereby driving the sleeve 9 to axially displace along the central shaft 8, and the telescopic guide rod 22 ensures the linear stability of the moving path.

[0041] Through the above design, the two motors 19 can respectively drive the two turning components to rotate, and the two electric push rods 23 can respectively drive the two turning components to move axially, thereby controlling the material prying piece 10 accordingly according to different frying stages.

[0042] During operation, the equipment operates in three phases: feeding, frying, and refilling. During the feeding phase, the equipment is first started, and the heating assembly 5 begins heating the frying drum 1. Motor 16 drives the frying drum 1 in a constant forward rotation. Simultaneously, the two sleeves 9 of the turning assembly move toward the center of the frying drum 1, interlacing spirally. Solenoid valve 7 is opened, and the feed bin 6 delivers a predetermined weight of material into the feed inlet 3. Then, solenoid valve 7 is closed, completing the feeding process. Entering the frying phase, since the reducing section 102 is now separated from the closing portion 11, the frying drum 1 does not push out material regardless of forward or reverse rotation. The turning assembly's paddle 10 rotates independently, either at the same speed as the frying drum 1, at a different speed, or even in the opposite direction. The paddle 10 actively turns the material, cooperating with the paddle plate 12 to push the material back and forth axially. This significantly increases the material's tumbling frequency and path diversity, ensuring more uniform heat transfer and rapidly discharging moisture from both the feed inlet 3 and the discharge port 4. This significantly improves frying efficiency and prevents localized overheating or over-humidity.

[0043] After the material is roasted, it enters a continuous feeding and discharging mode. The two flipping assemblies first work together to convey the material toward the discharge port 4, concentrating the material on the flipping assembly near the discharge port 4. The electric push rod 23 then drives the flipping assembly on this side along the central axis 8 toward the discharge port 4, allowing the reducing section 102 to once again maintain a slight gap with the inner wall of the closing portion 11. Its sleeve 9 rotates the paddle 10, conveying the material toward the discharge port 4. Simultaneously, the flipping assembly near the feed port 3 moves adjacent to the feed port 3, where its rotating paddle 10 forms a physical barrier, preventing new material from flowing toward the center of the roasting cylinder 1. At this point, the solenoid valve 7 of the feed bin 6 opens in response to a signal from the weighing device 25, allowing new material to be added through the feed port 3. However, due to the restriction of the paddle 10 at the feed port 3, new material does not mix with the already roasted material being discharged.

[0044] After discharge, the flipping components at the four ends of the discharge port return to their original positions, eliminating the need for machine downtime and enabling seamless, continuous production. This simultaneous feeding and discharging mechanism not only resolves the conflict between feeding and discharging in traditional equipment, but also maximizes time utilization through the independent action of the flipping components, significantly increasing production capacity.

[0045] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
