Description

Technical Field

[0001] This invention relates to the field of peanut production, and more particularly to a peanut rotary roasting device. Background Technology

[0002] Traditional peanut roasting equipment often has limitations in terms of efficiency, uniformity, and automation. Common hot air ovens or drum roasting equipment suffer from uneven heating, scorching, or undercooking, resulting in inconsistent peanut flavor and quality. Manual roasting is not only labor-intensive but also difficult to control precisely, easily leading to safety hazards. Existing equipment often relies on gravity or simple mechanical turning during unloading, which can easily cause peanut accumulation, breakage, or incomplete unloading, affecting the integrity of the finished product and batch processing efficiency. The debris and hot gas emissions generated during roasting also lack effective management. Debris accumulation contaminates the equipment and products, while high-temperature and humid air accumulation interferes with the constant temperature roasting environment, lengthening the processing cycle and increasing energy consumption. In addition, the fixing methods of equipment components and operational safety are not adequately considered, such as accidental opening of the feed door or unreliable locking, which occur frequently. Therefore, there is an urgent need for a peanut rotary roasting equipment that integrates automatic stirring, precise temperature control, efficient unloading, debris recycling, and safe operation to solve pain points such as uneven heating, excessive manual intervention, difficulty in debris handling, high energy consumption, large fluctuations in finished product quality, and operational safety risks, and to meet the comprehensive requirements of modern food processing for efficiency, quality, and safety.

The baking machine 6 is connected to the output shaft of the motor 5. The baking machine 6 includes an air inlet 61, located on the outside of the baking machine 6, and having a circular structure; a first feeding inlet 62, located below the feeding hopper 3; and an arc-shaped structure 63, located inside the baking machine 6, used for... The peanuts are stir-fried to assist in the process. The exhaust port 7 is located at the top of the baking chamber 1. The second mounting side plate 8 is located on the left side of the baking chamber 1. The discharge baffle 9 is rotatably located at the lower part of the second mounting side plate 8. The discharge baffle 9 is equipped with a handle and a latch 91. There are two first locking parts 10, which are installed on the left side of the first mounting side plate 2 to lock the discharge baffle 9. The lower first locking part 10 is used to lock the discharge baffle 9 when it is not open, and the upper first locking part 10 is used to lock the discharge baffle 9 when it is open. The unloading mechanism 11 is slidably located in the baking chamber 1.

[0061] The unloading mechanism 11 includes a first drive assembly 111, which is mounted on the second mounting side plate 8. A lead screw is connected to the output shaft of the first drive assembly 111. The lead screw is rotatably connected to the inner side wall of the baking machine 6. A fixing member 115 is mounted on the left side inside the baking cavity 1. The fixing member 115 is rotatably connected to the lead screw. A rotating member 114 is rotatably connected to the lead screw. A bearing is provided inside the rotating member 114. The bearing is threadedly connected to the lead screw. The unloading plate 112 is mounted on the rotating member 114.

[0062] It also includes an exhaust mechanism 12, which includes a second drive assembly 121. The second drive assembly 121 is located on the upper rear side of the baking cavity 1. A guide rod 122 is located at the top inside the baking cavity 1. A connecting plate 124 is slidably connected to the guide rod 122 and threadedly connected to the second drive assembly 121. An adjusting plate 123 is connected to the left and right sides of the connecting plate 124 and slidably connected to the baking cavity 1 to seal the exhaust port 7. A temperature detector 125 is installed at the top inside the baking cavity 1 to detect the internal temperature of the baking cavity 1 in real time.

[0063] It also includes a recycling mechanism 13, which includes a collection frame 131. The collection frame 131 is slidably disposed at the bottom of the baking cavity 1. A filter screen is disposed on the collection frame 131. A limiting structure 132 is disposed on the left and right sides of the bottom of the baking cavity 1 to limit the sliding of the collection frame 131. A second locking member 133 is rotatably connected to the baking cavity 1 to limit and block the collection frame 131.

[0064] It also includes an auxiliary feeding mechanism 14, which includes a feeding frame 141. The feeding frame 141 is provided at the top of the feeding frame 141. An inclined plate 142 is provided inside the feeding frame 141. A soft pad 143 is provided inside the right side of the feeding frame 141. A flip cover 144 is rotatably provided on the upper left side of the feeding frame 141. The discharge structure 15 is installed on the second mounting side plate 8 and is located below the discharge baffle 9.

[0065] It should be noted that the working principle of the peanut rotary roasting equipment is based on the synergistic effect of its overall structure and components to achieve a highly efficient and automated peanut roasting process. At the start of operation, the operator opens the feeding frame 141 through the flip-top 144 of the auxiliary feeding mechanism 14 and puts the peanuts inside. The inclined plate 142 guides the peanuts to slide smoothly into the feeding hopper 3 to reduce the impact upon initial entry. The soft pad 143 set on the right side of the feeding frame 141 can buffer the peanuts from collision and prevent damage. The peanuts enter the roasting chamber 1 from the feeding hopper 3. At the same time, the motor 5 starts and drives the output shaft to rotate through the mounting point on the right side of the first mounting side plate 2, connecting the roaster 6 to make it rotate in the roasting chamber 1. The heating tube 4 is installed in the roasting chamber 1 to provide a constant temperature heat source. The outside of the roaster 6 is provided with a circular air inlet 61 to introduce external air. Air-assisted temperature balancing is achieved by continuously stirring the peanuts in the rotating arc-shaped structure 63 within the roaster 6, ensuring even heating and preventing localized scorching, thus promoting uniform flavor release. At this time, the exhaust mechanism 12 automatically intervenes. The second drive assembly 121, based on the real-time temperature signal monitored by the temperature detector 125 inside the roasting chamber 1, guides the connecting plate 124 to slide on top of the roasting chamber 1 via the guide rod 122. The connecting plate 124 drives the adjusting plates 123 on both sides to open or close the exhaust ports 7. When excessively high temperatures are detected, the second drive assembly 121 causes the adjusting plates 123 to open the exhaust ports 7 to release excess hot steam. Sliding the adjusting plates 123 to close the exhaust ports 7 maintains the temperature within the chamber, ensuring the peanut temperature remains stable within the preset range during roasting and preventing overheating. During roasting or under-roasting, the exhaust mechanism 12 and heating tube 4 work in coordination to optimize energy efficiency and reduce energy consumption. During the rotating and roasting process, some peanut fragments or residues fall and are captured by the collection frame 131 of the recycling mechanism 13. The collection frame 131 is slidably positioned at the bottom of the roasting chamber 1, with limit structures 132 on both sides to ensure its fixed position. The filter screen on the collection frame 131 filters air and isolates larger fragments for easy later cleaning. The second locking element 133 is rotatably connected to the roasting chamber 1 to lock the collection frame 131 and prevent movement. When roasting is complete, the operator operates the discharge baffle 9, unlocking the latch 91 to release the locking state of the lower first locking element 10, allowing the discharge baffle 9 to rotate open. The upper first locking element 10 is then used to fix its open position. Then, the unloading mechanism 11 is activated. A drive assembly 111 operates on the second mounting side plate 8, rotating via a lead screw supported by a fixing member 115. The lead screw is rotatably connected to the inner wall of the roaster 6. The rotating part 114 on the lead screw is driven by a built-in bearing thread, causing the unloading plate 112 to slide along the inner wall of the roaster 6, pushing the peanuts towards the discharge port. The unloading plate 112 effectively pushes the peanuts with the assistance of the inclined surface of the arc structure 63 of the roaster 6, avoiding residue. After the peanuts are discharged from the discharge baffle 9, they are collected by the discharge structure 15, which is installed at the lower part of the second mounting side plate 8 for easy reception by downstream containers. During the discharge process, the operator can adjust the discharge speed at any time according to the needs to ensure product integrity. During the operation of the entire equipment, the motor 5 continuously provides power, and the hot air circulation and exhaust regulation of the heating tube 4 form a closed-loop temperature control system.The debris collected by the recycling mechanism 13 can be cleaned and reassembled through the sliding collection frame 131 to maintain equipment hygiene. During the initial feeding stage, the auxiliary feeding mechanism 14 controls the feeding rhythm through the flip cover 144, the inclined plate 142 provides directional guidance, and the soft pad 143 protects the soft material on the peanut surface, reducing damage and improving raw material utilization. The arc-shaped structure 63 of the roasting machine 6 continuously tumbles the peanuts during tumbling, combined with uniform heat penetration, shortening roasting time and improving efficiency. The first mounting side plate 2 and the second mounting side plate 8 jointly support the overall frame. The first mounting side plate 2 fixes the feed hopper 3 and the motor 5 output, while the second mounting side plate 8 carries the discharge baffle 9 and part of the unloading mechanism 11. All locking components ensure safe operation and prevent accidental opening. When the unloading plate 112 finishes sliding, the inside of the roasting chamber 1 is cleaned, the first drive component 111 stops, and the temperature detector 125 provides data to assist user decision-making. The entire process, from feeding, frying, temperature control, discharge to recycling, is completed in one step, achieving seamless integration, high efficiency, and energy saving, ultimately ensuring uniform roasting, delicious color, aroma, and taste with no waste.

[0066] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
