Description
Technical Field
[0001] This invention relates to the field of nut processing equipment technology, and in particular to a continuous roasting pan for sunflower seeds used in food processing. Background Technology
[0002] In the food processing industry, continuous roasting pans for sunflower seeds (also known as "continuous roasting production lines for sunflower seeds") are the core equipment for achieving large-scale and automated processing of sunflower seeds. This production line typically consists of modules for feeding, roasting, seasoning, air separation / sieving, and cooling, forming a continuously operating integrated system that sequentially completes the entire process of quantitative feeding, heating and cooking, seasoning application, impurity separation, and finished product cooling, significantly improving production efficiency and scale. The technical functions of each module are as follows: The feeding unit uses a screw or belt conveyor to stably transport the sunflower seed raw materials to the roasting unit at a preset flow rate, avoiding fluctuations caused by manual feeding and ensuring the stability of subsequent processes; the roasting unit, as the core, uses a roller or trough structure for heating and stirring, so that the sunflower seeds are evenly heated during transportation, achieving dehydration, ripening, and flavor formation; the seasoning unit is equipped with auxiliary material storage, metering, and spraying devices, which can accurately add seasonings such as sugar and salt to the sunflower seeds during the roasting process, and ensure even adhesion through stirring; the air separation / sieving unit uses airflow or screens to separate impurities such as broken shells and shriveled kernels from the sunflower seeds, improving the purity of the finished product; the cooling unit uses a belt or chain plate conveyor structure combined with forced air cooling to quickly reduce the temperature of the sunflower seeds, avoiding moisture or oxidation caused by residual heat, and ensuring product quality and shelf life.
[0003] However, after seasoning, the surface of the sunflower seeds is covered with soluble additives such as sugar and salt. During the process of entering the cooling unit, due to the residual heat of the sunflower seeds, temperature differences, and friction with the conveyor chain, these additives are very easy to adhere to the conveyor chain of the existing conveying device, forming a stubborn sugar and salt scale layer. Long-term accumulation can easily breed microorganisms and directly contact subsequent batches of sunflower seeds, causing cross-contamination.
[0004] Therefore, in view of the above situation, there is an urgent need to develop a continuous roasting pan for sunflower seeds for food processing to overcome the shortcomings in current practical applications. Summary of the Invention

[0009] In a further technical solution, racks are fixedly connected to the inner wall of the second slide groove, and the two racks on the same side are symmetrical about the fixed plate.

[0013] In summary, the embodiments of the present invention have the following beneficial effects compared with the prior art: 1. The raised areas of the conveyor chain plate can be immersed in hot water in the water tank. The hot water in the water tank dissolves soluble auxiliary materials (such as sugar, salt and other seasoning residues) adhering to the surface of the chain plate, reducing the adhesion of sticky impurities from the source. The chain plate is then further cleaned by a cylindrical brush after dissolving, thus avoiding cross-contamination. 2. The inner and outer scrapers physically remove stubborn adhering substances (such as burnt residue and broken sunflower seed shells) from the inner and outer surfaces of the chain plate, solving the problem of hard impurities that are difficult to handle with a brush. 3. The cylindrical brush rotates synchronously during the sliding process (driven by the meshing of the rack and pinion and the third gear), which enables deep cleaning of the chain plate surface. The nozzle swings back and forth on the vertical plane to rinse along the movement trajectory of the brush, and is then dried by the subsequent blower to avoid secondary adhesion of residual water stains or impurities after cleaning. 4. The spacing of the receiving plates is controlled by the adjustable spacing component, which enables rapid switching between the "scraping mode" and the "brush + rinsing mode": When the receiving plates move away from each other, the scraping mode is triggered (the inner scraper / outer scraper abuts against the chain plate) to remove stubborn impurities; when the receiving plates move closer to each other, the mode is switched to "brush + rinsing mode" to complete fine cleaning. The switching process does not require manual intervention and is controlled by one button via the electric telescopic rod, with a fast response speed. 5. A single motor drives multiple sets of cooperating rods to rotate synchronously, which not only ensures the consistency of the brush sliding and nozzle swinging movements, but also reduces the number of motors used, thereby reducing equipment procurement costs and operating energy consumption.

[0017] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0018] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.
[0019] like Figures 1-9 As shown, this embodiment of the invention provides a continuous roasting pan for sunflower seeds for food processing, including a feeding unit, a roasting unit, a seasoning unit, a sieving unit, and a cooling unit. The feeding unit, roasting unit, sieving unit, and cooling unit are arranged sequentially, and the seasoning unit is arranged in conjunction with the roasting unit. The cooling unit includes a conveying device 1, side plates 24, and fans 26. The conveying device 1 is provided with symmetrical side plates 24, and multiple fans 26 are provided on one side of the side plate 24. The fans 26 force-cool the sunflower seeds conveyed on the conveying device 1. Multiple sprocket shafts are added between the bottoms of the two side plates 24 of the conveying device 1, and each sprocket shaft is equipped with a sprocket that meshes with the conveying chain. The base plate of the conveying device 1 is equipped with a lifting structure 2. A water tank 3 is fixedly connected to the upper end of the lifting structure 2. The chain plate of the conveying device 1 is immersed in hot water by the cooperation of the lifting structure 2 and the water tank 3. The bottom ends of the two side plates 24 are fixedly connected to a connecting plate 10 and a plurality of first connecting rods 4. The connecting plate 10 and the first connecting rods 4 are fixedly connected. A fixing plate 6 is fixedly connected between the plurality of first connecting rods 4 on the same side plate 24. A receiving plate 5 symmetrical about the fixing plate 6 is slidably connected to the first connecting rod 4. An adjusting component 7 is provided between the plurality of receiving plates 5. The adjusting component 7 is used to adjust the distance between the receiving plate 5 and the fixing plate 6. A second sliding groove 8 is opened on one side of each receiving plate 5. A matching rod 9 is connected in each of the second sliding grooves 8. Two threaded rods 9 on one side are fitted together with a drive assembly 11. The drive assembly 11 drives the fitted rods 9 to rotate. A first slider 12 is also slidably connected in the second groove 8. A rotating rod 13 is rotatably connected between two corresponding first sliders 12 on different sides. A cylindrical brush 14 is fixedly sleeved on the outer wall of the rotating rod 13.
[0020] It is understood that the lifting structure 2 is existing technology and is used to lift the water tank 3.
[0021] Specifically, by adding multiple sprocket shafts between the bottoms of the two side plates 24 of the conveying device 1, and assembling sprockets that mesh with the conveying chain on each sprocket shaft, when the conveying chain plate runs to the position of the sprocket shaft and sprocket, the supporting effect of the sprockets causes the conveying chain plate to form a raised structure, so that the raised area of the conveying chain plate can be immersed in the hot water in the water tank 3, ensuring that the soluble auxiliary materials adhering to the surface of the chain plate are fully in contact with the hot water to dissolve; the drive assembly 11 drives the mating rod 9 to rotate, and then the mating rod 9 drives the inner wall of the first slider 12 to slide, and then the first slider 12 drives the cylindrical brush 14 to move along the surface of the conveying chain plate for cleaning through the rotating rod 13, thereby further cleaning the impurities remaining on the surface of the chain plate.
[0022] Preferably, the two mating rods 9 on one side are threaded rods, which are threadedly connected to the first slider 12, and the two mating rods 9 on the other side are smooth rods, which are detachably connected to the inner wall of the second slide groove 8, and the smooth rods are slidably connected to the corresponding first slider 12.
[0023] Specifically, the cost can be effectively reduced by setting only one drive component 11 as needed. The drive component 11 drives the mating rod 9 to rotate, and then the mating rod 9 drives the inner wall of the first slider 12 to slide. After that, the first slider 12 drives the cylindrical brush 14 to move and clean along the surface of the conveyor chain plate through the rotating rod 13. The first slider 12 on the side without the drive component 11 slides synchronously through the rotating rod 13.
[0024] like Figures 4-7 As shown, two second rotating shafts 16 are rotatably connected between the two side plates 24. The two second rotating shafts 16 are located on the upper and lower sides of the lower chain plate. Symmetrical fixing rings 25 are fixedly sleeved on the second rotating shafts 16. Two first auxiliary rods 17 are fixedly connected to each fixing ring 25. An outer scraper 19 is fixedly connected between the two lower first auxiliary rods 17. An opening groove 23 is also provided on the side plate 24. An inner scraper concave plate 18 is detachably connected between the two upper first auxiliary rods 17, and the inner scraper concave plate 18 passes through the opening groove 23. A switching component 20 is provided between the fixing ring 25 and the threaded rod. A placement plate 21 is provided on the switching component 20, and a nozzle 22 is provided on the placement plate 21.
[0025] Specifically, when the adjusting component 7 drives the two receiving plates 5 to move away from each other, the receiving plate 5 drives the fixing ring 25 to rotate through the switching component 20. The fixing ring 25 drives the first auxiliary rod 17 to rotate and approach the lower chain plate until the first auxiliary rod 17 drives the inner scraper plate 18 and the outer scraper plate 19 to abut against the upper and lower surfaces of the lower chain plate, thereby scraping off the stubborn adhering substances on the lower chain plate. When the adjusting component 7 drives the two receiving plates 5 to approach each other, the receiving plates 5 drive the fixing ring 25 to rotate through the switching component 20. The fixing ring 25 drives the first auxiliary rod 17 to rotate away from the lower chain plate. Then, the driving component 11 drives the mating rod 9, which is a threaded rod, to rotate. The mating rod 9 drives the switching component 20 to move. The switching component 20 drives the placement plate 21 to swing back and forth, thereby adjusting the nozzle 22 to wash the chain plate from multiple angles. The washing coverage is high, avoiding cleaning dead corners, and the chain can also be washed. In addition, the impurities on the chain plate are mainly adhered to the outer surface of the chain plate, so they are mainly scraped off by the outer scraper 19. A small portion of the impurities on the inner surface of the chain plate are scraped off by the inner scraper 18 and temporarily stored in the groove of the inner scraper 18. Then, the impurities stored in the inner scraper 18 can be removed with tools when the inner scraper 18 is detached from the chain plate, or the inner scraper 18 can be disassembled to remove the impurities.
[0026] Understandably, the conveying device 1 can be placed in a groove opened in the ground to facilitate the collection of cleaned wastewater.
[0027] Furthermore, such as Figure 6 and Figure 7 As shown, racks 152 are fixedly connected to the inner wall of the second slide groove 8, and the two racks 152 on the same side are symmetrical about the fixed plate 6. Two third gears 151 are fixedly sleeved on the rotating rod 13, and the third gears 151 are respectively meshed with the corresponding racks 152.
[0028] Specifically, the first slider 12 slides along the inner wall of the second slide groove 8, and the first slider 12 drives the rotating rod 13 to move. Since the rack 152 is relatively stationary, during the movement of the rotating rod 13, the third gear 151 rotates under the meshing action of the rack 152. The third gear 151 drives the rotating rod 13 to rotate, and the two rotating rods 13 rotate in opposite directions. The rotating rod 13 drives the cylindrical brush 14 to rotate, so that the cylindrical brush 14 slides along the surface of the chain plate while rotating, thereby further improving the cleaning efficiency and effect.
[0029] like Figures 4-8 As shown, the adjustable distance assembly 7 includes a first sliding groove 71, an abutment rod 72, a first rotating shaft 73, a rotating plate 74, a second connecting rod 75, and an electric telescopic rod 76. The receiving plate 5 is provided with a first sliding groove 71, and an abutment rod 72 abuts within the first sliding groove 71. A first rotating shaft 73 is fixedly connected to the side of the fixing plate 6. A rotating plate 74 is rotatably connected to each of the first rotating shafts 73, and the rotating plate 74 is connected to the abutment rod 72. A second connecting rod 75 is fixedly connected between the two rotating plates 74, and an electric telescopic rod 76 is fitted onto the second connecting rod 75.
[0030] Specifically, when the cylindrical brush 14 needs to clean the two surfaces of the chain plate, the electric telescopic rod 76 is retracted, and then the electric telescopic rod 76 drives the second connecting rod 75 to move. The second connecting rod 75 drives the rotating plate 74 to rotate around the first rotating shaft 73. The rotating plate 74 drives the receiving plates 5 symmetrical about the fixed plate 6 to move closer to each other through the abutment rod 72. Then the receiving plates 5 drive the rotating rod 13 to move closer to each other through the first slider 12 until the rotating rod 13 drives the cylindrical brush 14 to abut against the inner and outer surfaces of the chain plate (lower chain plate). At this time, the inner scraper plate 18 and the outer scraper plate 19 move away from the inner and outer surfaces of the lower chain plate simultaneously. When the inner scraper 18 or the outer scraper 19 is needed to clean the two surfaces of the chain plate, the electric telescopic rod 76 is extended. Then the electric telescopic rod 76 drives the second connecting rod 75 to move. The second connecting rod 75 drives the rotating plate 74 to rotate around the first rotating shaft 73. The rotating plate 74 drives the upper and lower receiving plates 5 to move away from each other through the abutment rod 72. Then the receiving plate 5 drives the fixing ring 25 to rotate through the switching component 20. The fixing ring 25 drives the first auxiliary rod 17 to rotate and move closer to the chain plate. Multiple first auxiliary rods 17 respectively drive the inner scraper 18 and the outer scraper 19 to abut against the inner and outer surfaces of the chain plate (lower chain plate). At this time, the cylindrical brush 14 moves away from the inner and outer surfaces of the lower chain plate simultaneously.
[0031] like Figures 4-7 and Figure 9As shown, the drive assembly 11 includes a motor 111, a first mating groove 112, a first gear 113, a second gear 114, a rotating cylinder 115, a limiting strip 116, and a drive rod 117. The receiving plate 5 has a first mating groove 112, within which a rotating cylinder 115 is rotatably connected. The inner wall of the rotating cylinder 115 has multiple limiting grooves (not marked in the figure). A drive rod 117 is slidably connected to the inner wall of the rotating cylinder 115. Multiple limiting strips 116 are fixedly connected to the outer wall of the drive rod 117, and the limiting strips 116 abut against the inner wall of the limiting grooves. One end of the mating rod 9, which serves as a threaded rod, is fixedly connected to the first gear 113. The outer wall of the rotating cylinder 115 is fixedly fitted with the second gear 114, which meshes with the first gear 113. The connecting plate 10 has a motor 111 fixedly connected to it, and the drive end of the motor 111 is fixedly connected to the drive rod 117.
[0032] Specifically, the drive end of motor 111 drives drive rod 117 to rotate. Then, drive rod 117 drives rotating drum 115 to rotate through limit bar 116 and limit groove. Next, rotating drum 115 drives second gear 114 to rotate, then second gear 114 drives first gear 113 to rotate, and first gear 113 drives mating rod 9 to rotate, thereby ensuring that multiple mating rods 9 rotate synchronously and ensuring consistent cleaning action. When the distance adjustment component 7 controls the two receiving plates 5 to move away from or close to each other, limit bar 116 slides along the inner wall of limit groove, thereby preventing the lifting of first connecting rod 4 from obstructing the rotation of mating rod 9 driven by drive component 11. Multiple mating rods 9 can be rotated by one motor 111, reducing the number of motors 111 used, ensuring synchronous rotation of multiple mating rods 9 and reducing costs.
[0033] like Figure 4 , Figure 6 , Figure 7 and Figure 9 As shown, the switching assembly 20 includes a second slider 201, an intermediate plate 202, a slip ring 203, a second auxiliary rod 204, and a second mating groove 205. The inner wall of each of the second sliding grooves 8 is provided with a second mating groove 205, and the second mating grooves 205 on the same side are symmetrical about the fixed plate 6. The outer wall of the mating rod 9 is fitted with the second slider 201, and the second slider 201 is slidably connected to the inner wall of the second sliding groove 8. Each of the fixed rings 25 is fixedly connected with a second auxiliary rod 204, and each of the second auxiliary rods 204 is slidably connected to a slip ring 203. Each of the slip rings 203 is fixedly connected with an intermediate plate 202, and the other end of the intermediate plate 202 is rotatably connected to the second slider 201. A placement plate 21 is fixedly connected between two corresponding intermediate plates 202 on different sides.
[0034] Specifically, when the cylindrical brush 14 needs to clean the two surfaces of the chain plate, the two receiving plates 5 are brought closer together by the adjusting component 7. Then, the receiving plates 5 are brought closer together by the first slider 12 and the rotating rod 13 until the rotating rod 13 brings the cylindrical brush 14 to the inner and outer surfaces of the chain plate (lower chain plate). During this process, the receiving plate 5 drives the second slider 201 to descend. The second slider 201 drives the slip ring 203 to descend by the middle plate 202. Then, the slip ring 203 drives the second auxiliary rod 204 to rotate around the axis of the second rotating shaft 16. Then, the second auxiliary rod 204 drives the fixed ring 25 to rotate. The fixed ring 25 drives the first auxiliary rod 17 to rotate away from the chain plate, thereby driving the inner scraper plate 18 and the outer scraper plate 19 away from the chain plate. This allows for quick switching of working modes and saves time. When the drive assembly 11 drives the mating rod 9 to rotate, the mating rod 9 drives the second slider 201 to slide along the inner wall of the second slide groove 8. Then the second slider 201 moves through the slip ring 203. The slip ring 203 slides along the outer wall of the second auxiliary rod 204 while driving the second mating groove 205 to rotate around the axis of the second rotating shaft 16. By changing the rotation direction of the drive shaft of the motor 111, the rotation direction of the mating rod 9 can be changed, thereby changing the sliding direction of the first slider 12 and the second slider 201, and also changing the rotation direction of the second mating groove 205 around the axis of the second rotating shaft 16. The motor 111 controls the first slider 12 and the second slider 201 to slide back and forth. During this process, the intermediate plate 202 drives the placement plate 21 to swing back and forth. The placement plate 21 drives the nozzle 22 to swing back and forth, and then rinses the chain plate surface after it has been cleaned by the cylindrical brush 14. It follows the movement of the cylindrical brush 14 to rinse in real time. The chain plate is rinsed from multiple angles by swinging to avoid omissions.
[0035] The working principle of this invention is as follows: the feeding unit transports the sunflower seed raw material to the roasting unit for dehydration and cooking. Then, during the roasting process, the seasoning unit precisely adds seasonings such as sugar and salt to the sunflower seeds. Afterward, the air separation / screening unit uses airflow or a screen to separate impurities such as broken shells and shriveled kernels from the sunflower seeds, thereby improving the purity of the finished product. After being processed by the air separation / screening unit, the sunflower seeds are transported to the conveying device 1 of the cooling unit. Then, the sunflower seeds are forced to cool by the fan 26. After cooling, they are transported to the storage device for storage. When processing different batches of sunflower seeds, firstly, the lifting structure 2 is controlled to raise the water tank 3, so that the raised area of the conveyor chain plate is immersed in the hot water in the water tank 3. The hot water dissolves the soluble auxiliary materials adhering to the surface of the chain plate. Then, the adjusting component 7 drives the two receiving plates 5 on the same first connecting rod 4 to move away from each other. Then, the receiving plate 5 drives the fixing ring 25 to rotate through the switching component 20. The fixing ring 25 drives the inner scraper 18 and the outer scraper 19 to abut against the inner and outer surfaces of the lower chain plate through the first auxiliary rod 17, thereby scraping off the stubborn adhering materials of the lower chain plate and effectively reducing the subsequent cleaning pressure. Secondly, in the next revolution of the chain plate movement, the two receiving plates 5 on the same first connecting rod 4 are controlled to move closer to each other by the adjusting component 7. Then, the receiving plates 5 are driven by the first slider 12 to move the rotating rod 13 closer to each other until the rotating rod 13 drives the cylindrical brush 14 to abut against the inner and outer surfaces of the chain plate (lower chain plate). At this time, the receiving plates 5 drive the fixing ring 25 to rotate by the switching component 20. The fixing ring 25 drives the first auxiliary rod 17 to rotate away from the lower chain plate, thereby driving the inner scraper plate 18 and the outer scraper plate 19 away from the chain plate. Subsequently, the drive assembly 11 drives the mating rod 9 to rotate, and the mating rod 9 drives the first slider 12 and the second slider 201 to slide back and forth along the inner wall of the second slide groove 8. The first slider 12 drives the cylindrical brush 14 to move along the surface of the conveyor chain plate for cleaning through the rotating rod 13. Since the rack 152 is relatively stationary, the third gear 151 rotates under the meshing action of the rack 152 during the movement of the rotating rod 13. The third gear 151 drives the rotating rod 13 to rotate, and the two rotating rods 13 rotate in opposite directions. The rotating rod 13 drives the cylindrical brush 14 to rotate, so that the cylindrical brush 14 slides along the surface of the chain plate while rotating, thereby further improving the cleaning efficiency and effect. The second slider 201 drives the slip ring 203 to move via the intermediate plate 202. While the slip ring 203 slides along the outer wall of the second auxiliary rod 204, it drives the second mating groove 205 to rotate around the axis of the second rotating shaft 16. By changing the rotation direction of the drive shaft of the motor 111, the rotation direction of the mating rod 9 can be changed, thereby changing the sliding direction of the first slider 12 and the second slider 201, and also changing the rotation direction of the second mating groove 205 around the axis of the second rotating shaft 16. The motor 111 controls the first slider 12 and the second slider 201 to slide back and forth. During this process, the intermediate plate 202 drives the placement plate 21 to swing back and forth, and the placement plate 21 drives the nozzle 22 to swing back and forth, and then rinses the chain plate surface after it has been cleaned by the cylindrical brush 14, and then dries it by the blower 26.
