Description

Technical Field

[0001] This invention relates to the field of food processing equipment technology, specifically to a sesame roasting and cooling smoke removal device. Background Technology

[0002] Sesame seeds are typically heated to high temperatures during roasting, causing internal moisture to evaporate, oils to be released, and aroma to develop, resulting in roasted sesame seeds with a rich fragrance. However, after roasting, the temperature of sesame seeds often exceeds 150℃. If not cooled promptly, this can lead to problems such as surface charring, oil oxidation, and a bitter taste, as well as affecting the product's storage stability and nutritional content. Furthermore, the cooling process of high-temperature sesame seeds releases a large amount of fumes and oil mist. These fumes contain oil particles and volatile organic compounds (VOCs), which, if left untreated, will pollute the workshop air and negatively impact worker health and the surrounding environment.

[0003] In the prior art, for example, Chinese patent CN201910241883.8 discloses a rapid cooling device for roasted nuts and seeds. This device uses rapid shaking and cold air cooling to cool the roasted nuts and seeds inside the device. However, if the roasted nuts and seeds are only shaken rapidly during the cooling process without releasing the oil mist and fumes trapped between them in time, it is difficult to achieve a rapid cooling effect. Furthermore, the hot air usually rises naturally and accumulates at the top of the device. If it is not released in time, it will form liquid, which will affect the quality and taste of the roasted nuts and seeds inside the device. Therefore, there are still some technical problems with the existing cooling devices for roasted nuts and seeds. Summary of the Invention

[0004] In order to solve the technical problems mentioned in the background art, the present invention provides a sesame roasting and cooling smoke removal device to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A sesame roasting and cooling smoke removal device includes a mounting frame with a cover at the top. A storage bin is rotatably mounted on the middle of the mounting frame and placed below the cover. A water tank is conductively connected to one side of the cover. A transmission assembly is mounted on the side of the cover away from the water tank. A lifting shaft is rotatably mounted in the middle of the cover, perpendicular to the cover surface and extending downward into the storage bin. A gear rail is circumferentially arranged around the outside of the storage bin. A shaft seat is rotatably mounted at the bottom of the storage bin cavity, with its upper end connected to the lifting shaft. Multiple stirring rods are circumferentially arranged around the outside of the shaft seat, with the stirring rods adjacent to the inner wall of the storage bin cavity. A first transmission shaft extending to the outside of the storage bin is located at the lower end of the shaft seat. The transmission assembly is connected from top to bottom to the lifting shaft, the gear rail, and the first transmission shaft.

[0006] Preferably, the upper end of the cover has a feed inlet and the lower end of the storage bucket has a discharge outlet. The cover is wrapped around the upper port of the storage bucket. The storage bucket has a retainer around its outer circumference. The mounting ring with an inner groove is provided in the middle of the mounting frame corresponding to the retainer position. The retainer on the outer side of the storage bucket is embedded in the groove on the inner side of the mounting ring, and the storage bucket can rotate within the mounting ring along its central axis.

[0007] Preferably, one side of the water tank is conductively connected to the cover, and a smoke vent is opened on the upper side of the side of the water tank away from the cover. The water tank is hollow inside, and a baffle extending downward to the middle of the upper end of the water tank cavity is provided. The baffle divides the space on both sides of the water tank cavity and forms a U-shaped loop.

[0008] Preferably, the transmission assembly includes a gearbox with inwardly extending bevel gears rotatably embedded on both sides of the gearbox. A downwardly extending transmission sleeve is rotatably disposed inside the gearbox. A first transmission gear is disposed in the middle of the transmission sleeve and meshes with a gear rail for transmission. A first helical gear is disposed at the upper end of the transmission sleeve, which is placed inside the gearbox and located at the lower end of the two bevel gears and meshes with the two bevel gears.

[0009] Preferably, a second drive shaft is rotatably provided inside the gearbox. The second drive shaft is disposed inside the drive tube sleeve, and both its upper and lower ends extend outside the drive tube sleeve. A first synchronous belt is connected between the upper end of the second drive shaft and the lifting shaft. The lowermost end of the second drive shaft is connected to the first drive shaft, and a drive motor is coaxially connected to the lower end of the second drive shaft. A second helical gear is provided on a section of the second drive shaft placed in the gearbox. The second helical gear is placed on the upper end of the two bevel gears and meshes with the two bevel gears.

[0010] Preferably, a lifting auger is provided around the outer circumference of the lifting shaft, and the lower end of the lifting shaft is rotatably embedded in the shaft seat.

[0011] Preferably, the stirring rod extends outward from the inner bottom plate of the storage tank. The extended end of the stirring rod is bent and extends towards the upper port of the storage tank along the inner side wall. Each stirring rod is provided with multiple blades, and a stabilizing component is provided on the end of the stirring rod near the upper port of the storage tank.

[0012] Preferably, the stabilizing component includes a hook extending from the extension end of the stirring rod towards the outer side of the upper port of the storage tank, and a clamping plate with an opening facing the outer wall of the storage tank is provided on the inner side of the hook, and a movable pulley with its side attached to the outer wall of the storage tank is installed in the clamping plate.

[0013] Preferably, a support frame is provided between each of the multiple adjacent extension ends of the stirring rods, and the support frame is two parallel arc-shaped plate structures. The two ends of the support frame are fixedly connected to the two adjacent extension ends of the stirring rods, and the multiple support frames are arranged in a ring structure. Fan blades are arranged in an array in the middle of the support frame.

[0014] Preferably, the fan blade is a plate-like structure with one side bent at a 30-degree angle.

[0015] The present invention has the following beneficial effects: This invention utilizes a transmission component on one side of the lid, employing a transmission sleeve and a second transmission shaft that rotate coaxially and in opposite directions. This allows the drive motor to drive the first transmission shaft and the storage bin to rotate in opposite directions via the second transmission shaft, thus achieving simultaneous rotation of the entire bin and the internal stirring rod. A toothed track is installed on the outside of the storage bin, meshing with the first transmission gear inside the transmission sleeve. This reverse transmission creates a two-layer rotating system, causing the sesame material to move in a "stirring-scattering-spreading" state within the storage bin. This promotes thorough material agitation, effectively increasing the contact area between the sesame and air, enhancing the natural and forced convection heat transfer processes, and significantly improving the heat dissipation rate.

[0016] When the second drive shaft rotates in the opposite direction, the auger pulls the material upwards along the axial direction. At the same time, the stirring rod on the bottom bearing of the storage tank rotates synchronously and tumbles along the tank wall. The sesame seeds form a three-dimensional flow trajectory of alternating upward and rotating motion inside the tank. This causes the sesame seeds to exhibit a cyclical state of "spiral ascent - free fall - re-tumbling" during the cooling process, effectively preventing the sesame seeds from accumulating and clumping, greatly improving the uniformity of heat dissipation, and avoiding localized overheating.

[0017] The fan blades rotate synchronously under the drive of the upper extension of the stirring rod. The rotation of the fan blades creates a negative pressure airflow, guiding the high-temperature fumes and oil mist released during the sesame cooling process towards the water tank on one side of the cover. Unlike natural diffusion exhaust, the fan blades of this invention form a stable directional flow channel, allowing the fumes to be collected and guided before escaping, thus significantly improving fumes collection efficiency and reducing oil mist diffusion within the workshop. The water tank connected to one side of the cover has a hollow structure with downward-extending baffles inside, dividing the cavity space into a U-shaped return channel. When the fan blades guide the fumes into the water tank, the fumes must travel along the baffles and pass through the liquid surface, ensuring full contact with the water. Oil particles and suspended matter entrained in the fumes are condensed, adsorbed, and settled in the water during the gas-liquid contact process, while the purified clean gas is discharged through the exhaust port at the top of the water tank.

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] In the description of this invention, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0023] This invention provides a sesame roasting cooling and smoke removal device, which addresses the problems of uneven sesame cooling, low cooling efficiency, serious smoke diffusion pollution, and incomplete smoke removal and purification in existing roasting equipment. By forming a multi-axis linkage and gas-liquid synergistic purification system between the storage tank 4, transmission components, water tank 3 and fan blade 805, it achieves the dual functions of automatic turning cooling and simultaneous smoke removal and purification.

[0024] Example 1: like Figure 1-2 This invention provides a sesame seed roasting and cooling smoke removal device, comprising a mounting frame 1, a cover 2 at the upper end of the mounting frame 1, and a storage bin 4 rotatably mounted in the middle of the mounting frame 1. The cover 2 covers the upper port of the storage bin 4. A purified water tank 3 is connected to one side of the cover 2 via a conductive pipe, and a transmission component is installed on the side of the cover 2 away from the water tank 3. A lifting shaft 7 is rotatably mounted vertically in the middle of the cover 2, and the lifting shaft 7 is perpendicular to the plane of the cover 2 and extends downward into the cavity of the storage bin 4.

[0025] like Figure 4 As shown, a toothed rail 402 is arranged around the outer circumference of the storage tank 4. A bearing seat 810 is rotatably mounted at the bottom of the storage tank 4 cavity, and the upper end of the bearing seat 810 is connected to the lifting shaft 7. Multiple stirring rods 801 are evenly arranged around the outer circumference of the bearing seat 810, and the stirring rods 801 are arranged along the direction of the tank wall and close to the inner side wall of the storage tank 4. A first drive shaft 8 is provided at the lower end of the bearing seat 810. The first drive shaft 8 passes through the bottom of the storage tank 4 and extends to the outside of the storage tank 4, and is connected to the lower end of the transmission assembly. The transmission assembly realizes multi-stage linkage between the lifting shaft 7, the toothed rail 402 and the first drive shaft 8, so that the storage tank 4, the stirring rods 801 and the lifting auger 701 form a counter-rotating relationship.

[0026] like Figure 1As shown, the mounting frame 1 adopts a ring-shaped support frame structure with a mounting ring 101 in the middle. An annular groove is formed on the inner side of the mounting ring 101. An annular retainer 403 is provided around the outer circumference of the storage bin 4, and the retainer 403 can be inserted into the groove of the mounting ring 101. The storage bin 4, through the cooperation of the retainer 403 and the mounting ring 101, can rotate stably along the central axis within the mounting frame 1. This embedded connection method ensures smooth rotation of the storage bin 4 and facilitates disassembly and cleaning.

[0027] The storage hopper 4 is a cylindrical structure made of metal, with a discharge port 401 at the lower end and the upper end covered by a cover 2. The connection between the bottom of the hopper and the shaft seat 810 adopts a sealed bearing structure to prevent the leakage of flue gas and dust.

[0028] like Figure 1 As shown, a feed inlet 201 is provided in the middle of the upper part of the cover 2 to facilitate the addition of roasted sesame seeds. One side of the cover 2 is connected to the water tank 3 through a pipe. A transmission component is provided on the side of the cover 2 away from the water tank 3, forming a symmetrical layout of "power input end" and "smoke output end".

[0029] like Figure 3 As shown, one side of the water tank 3 is electrically connected to the cover 2 to receive the flue gas introduced into the cover 2. A flue gas outlet 301 is opened at the upper end of the side of the water tank 3 furthest from the cover 2. The interior of the water tank 3 is hollow, with a downward-extending baffle 302 located in the middle of the upper part of the inner cavity. The baffle 302 divides the cavity of the water tank 3 into two spaces, forming a "U-shaped reflux" channel. After entering the water tank 3, the flue gas must circulate along the baffle 302, thereby extending the residence path of the flue gas in the water and improving the settling efficiency of oil mist and particles.

[0030] like Figure 7 As shown, the transmission assembly includes a gearbox 102, on which a pair of opposing bevel gears 103 are rotatably embedded. The gearbox 102 is hollow inside, and a transmission sleeve 5 is rotatably mounted at its center. A first transmission gear 502 is disposed in the middle of the outer side of the transmission sleeve 5, and the first transmission gear 502 meshes with the gear rail 402 on the outer side of the storage tank 4, thereby realizing the transmission of power from the transmission assembly to the storage tank 4.

[0031] like Figure 3 As shown, a first helical gear 501 is provided at the upper end of the transmission sleeve 5, and the first helical gear 501 meshes with the lower ends of the bevel gears 103 on both sides. A second transmission shaft 6 is also rotatably installed inside the gearbox 102. The second transmission shaft 6 passes through the transmission sleeve 5, and both its upper and lower ends extend outside the transmission sleeve 5. The upper end of the second transmission shaft 6 is connected to the lifting shaft 7 through a first synchronous belt 602 to form a belt drive structure. The lower end of the second transmission shaft 6 is connected to the first transmission shaft 8 through a coupling.

[0032] To achieve multi-stage reverse rotation, a second helical gear 601 is installed on a section of the second drive shaft 6 near the middle of the gearbox 102. The second helical gear 601 is located above the two bevel gears 103 and meshes with the upper ends of the two bevel gears 103. When the drive motor 604 drives the second drive shaft 6 to rotate, the upper and lower helical gears achieve reverse rotation between the transmission sleeve 5 and the second drive shaft 6, thereby driving the storage tank 4 to form a relative rotational relationship with the internal stirring mechanism.

[0033] The lifting shaft 7 is a hollow metal rod structure, vertically installed in the middle of the cover 2 and inserted into the storage tank 4. A spiral lifting auger 701 is arranged around the outer circumference of the lifting shaft 7, and the lower end of the lifting shaft 7 is embedded in the bearing seat 810, which can rotate with the transmission linkage.

[0034] When the transmission assembly drives the second transmission shaft 6 to operate, the second transmission shaft 6 drives the lifting shaft 7 to rotate through the synchronous belt. The auger slowly lifts the sesame particles at the bottom of the barrel to the top along the spiral direction, so that the sesame particles form an upward flow inside the barrel, thereby enhancing the material convection heat transfer.

[0035] Multiple stirring rods 801 are evenly distributed around the outer circumference of the shaft seat 810, with each stirring rod 801 set close to the inner wall of the storage tank 4. The stirring rods 801 extend upwards from the bottom of the shaft seat 810 along the tank wall, with the ends bending and extending upwards along the tank wall to the upper end of the storage tank 4, forming an "L"-shaped arc structure. Each stirring rod 801 has multiple equally spaced blades 802, which are used to push the sesame grains to tumble during rotation.

[0036] To ensure the rotational stability of the upper end of the stirring rod 801, a stabilizing component is provided at the upper extension of the stirring rod 801. The stabilizing component includes a hook 803, a clamping plate, and a movable pulley 804. The hook 803 extends from the end of the stirring rod 801 outwards towards the storage tank 4. An outward-facing clamping plate is installed on the inner side of the hook 803, and the movable pulley 804 is installed inside the clamping plate. The side of the movable pulley 804 is attached to the outer wall of the storage tank 4, thereby guiding and limiting the rotation of the stirring rod 801, effectively reducing vibration and friction.

[0037] A ring-shaped support frame is provided between the upper ends of multiple adjacent stirring rods 801. The support frame consists of two parallel arc-shaped plates, with both ends fixedly connected to the extension ends of adjacent stirring rods 801. Multiple support frames together form a ring-shaped frame, and several fan blades 805 are arrayed in the middle of the support frame.

[0038] The fan blade 805 is formed by bending a metal sheet, with a single-sided bend angle of approximately 30°. Driven by the rotation of the stirring rod 801, the fan blade 805 rotates synchronously to form a forced airflow. The airflow flows from the center of the storage tank 4 towards the water tank 3 on one side of the cover 2, thereby achieving directional guidance of the flue gas while cooling it down.

[0039] After the sesame seeds are roasted, the hot sesame material is poured into the storage hopper 4 through the feed inlet 201. The operator starts the motor, and the motor outputs power to the various transmission components via the second drive shaft 6. When the motor drives the second drive shaft 6 to rotate, the upper synchronous belt drives the lifting shaft 7 to rotate synchronously, while the transmission sleeve 5 rotates in the opposite direction through the bevel gear 103-helical gear set in the gearbox 102.

[0040] The first transmission gear 502 on the outer side of the transmission sleeve 5 meshes with the outer gear rail 402 of the storage tank 4, driving the storage tank 4 to rotate in the opposite direction. The reverse rotation of the storage tank 4 drives the bottom bearing 810 and the stirring rod 801 to rotate, while the stirring rod 801 moves in the opposite direction to the storage tank 4, forming a shear flow zone between them. Since the upper end of the stirring rod 801 is equipped with blades 802, during the reverse rotation, the blades 802 exert a continuous lifting and tumbling effect on the sesame seeds, causing the sesame seeds to be continuously lifted and fallen in the tank, promoting rapid heat dissipation.

[0041] Meanwhile, the auger on the outside of the lifting shaft 7 continuously lifts the sesame seeds from the bottom of the barrel to the top, creating a vertical circulating flow path inside the sesame seeds. The sesame particles inside the barrel are spiraled and tumbled by the lateral disturbance of the stirring rod 801 and the axial conveying action of the auger, achieving thorough mixing and convective heat transfer.

[0042] Driven by the reverse rotation of the stirring rod 801, the fan blade 805 on the support frame also rotates synchronously. When the fan blade 805 rotates, it creates a negative pressure airflow between the cover 2 and the storage tank 4. This airflow accelerates the flow of hot air inside the tank and promotes the cooling of the sesame seeds. On the other hand, it directs the oil mist and smoke released during the roasting process to the water tank 3 connected to the cover 2.

[0043] After entering water tank 3 through the conduit, the flue gas flows from the top of water tank 3 into the cavity space separated by baffle 302. Because baffle 302 divides the cavity into a U-shaped reflux channel, the flue gas is forced to change its flow direction when flowing over the liquid surface, thus ensuring full contact with the liquid. A large number of oil particles and suspended particles contained in the flue gas condense and settle on the liquid surface, forming an oil-water mixture that deposits at the bottom of water tank 3. The clean gas, after gas-liquid purification, is then discharged through the exhaust port 301 at the top of water tank 3, achieving simultaneous cooling and smoke removal.

[0044] Example 2: Pour an appropriate amount of purification solution (which can be clean water or an aqueous solution containing a small amount of adsorbent) into water tank 3. The liquid level should be approximately 1 / 2 to 2 / 3 of the height of the lower end of baffle 302. Check whether the transmission assembly and stirring rod 801 rotate flexibly.

[0045] Pour the freshly roasted hot sesame seeds into the storage container 4 through the feed inlet 201, and cover the container with the lid 2 to form a relatively sealed space to prevent the oil fumes from overflowing.

[0046] Start the drive motor 604, which drives the storage bin 4 to rotate in the opposite direction through the transmission system. The stirring rod 801 and the auger work together. The sesame seeds in the bin are continuously turned, scattered, and lifted, quickly achieving air convection cooling. The fan blade 805 at the top of the stirring rod 801 rotates to form an airflow, which introduces the oil fumes into the water tank 3. The fumes are then discharged after being purified by gas-liquid contact.

[0047] Once the sesame temperature drops to the set range, turn off the motor and open the discharge port 401 at the bottom of the storage tank 4 to discharge the cooled sesame seeds for packaging or screening.

[0048] After the equipment is used, open the cover 2 to separate it from the storage tank 4, and remove the clip 403 to disassemble and clean the storage tank 4. The oil-water mixture in the water tank 3 should be drained regularly and replaced with clean water to maintain the purification effect.

[0049] Without departing from the spirit of the present invention, the device can be further improved in the following ways: 1. A microbubble generator or activated carbon filter layer can be added to the bottom of water tank 3 to further improve the adsorption capacity of volatile organic compounds in flue gas.

[0050] 2. A temperature sensor is installed inside the storage hopper 4. When the temperature of the sesame seeds is detected to be lower than the set threshold, the motor will automatically stop running to achieve energy-saving control.

[0051] 3. By installing adjustable-angle fan blades 805, the airflow direction can be adjusted according to the direction of the on-site smoke exhaust outlet 301, thereby improving the airflow guidance efficiency.

[0052] 4. Add a transparent splash guard to the upper port of the storage hopper 4. This allows for observation of the material status while preventing material from splashing.

[0053] In summary, the sesame roasting cooling and smoke removal device of the present invention innovatively integrates three major functions—material cooling, oil fume collection, and gas-liquid purification—through the coordinated operation of the transmission components, water tank 3, and fan blade 805. Its core technical feature lies in the combination of a coaxial counter-rotating transmission system and a U-shaped water circulation purification system, achieving uniform cooling of sesame materials and efficient purification of the smoke.

[0054] The foregoing has shown and described the basic principles and main features of the present invention and its advantages. It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects. The scope of the present invention is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all changes falling within the meaning and scope of the equivalents of the claims be included within the present invention, and no reference numerals in the claims should be regarded as limiting the scope of the claims.

[0055] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
