Description

Technical Field

[0001] This invention relates to the field of coffee bean roaster technology, and more particularly to a coffee bean roaster. Background Technology

[0002] The smoke and silver husks produced during coffee roasting significantly affect the roasting quality. In the later stages of roasting, when the bean structure becomes loose and porous, the smoke may be reabsorbed by the coffee beans. Furthermore, under high temperatures, the thin, dry, and flammable silver husks can smolder and carbonize, producing a large amount of pungent, burnt smoke that further damages the flavor of the coffee beans. Typically, home ovens are used to roast coffee beans in specially designed baking baskets. This is economical and practical for home use, and it also effectively removes the silver husks during the roasting process.

[0003] A search revealed a Chinese patent document with publication number CN201610761741.0, which discloses a coffee roaster. The roaster includes an oven body, a catalyst block on the top shell of the oven body, a cyclone device on the rear shell, and a roasting basket in the inner cavity. An electromagnetic valve device for controlling the oven door is located above the control panel on the front side of the oven body, near the door frame. The roasting basket is connected to symmetrical support seats on corresponding side walls of the inner cavity via rotating shafts at both ends. The rotating shafts and support seats have a detachable / installable connection structure. One support seat has a rotating shaft, which, along with a corresponding rotating shaft tooth, passes through the corresponding side wall and connects to a drive device, thereby driving the roasting basket to rotate within the inner cavity. The electromagnetic valve device, located within the control panel, has a telescopic valve that can extend and retract from the control panel towards the oven door. This design solves the technical problem of roasting coffee beans in an oven, achieving a uniform roasting effect and easy removal of the coffee beans.

[0004] In existing technologies, although the roasting basket is actively rotated in the oven, and although the coffee beans expand and change at high temperatures, causing the silver skin on the surface to crack, the silver skin that actively falls off can be sifted out as the coffee beans roll during the rotation of the roasting basket. However, the silver skin on the surface of the beans does not fall off instantly. It occurs during a long period of continuous high-temperature roasting. There are still silver skin residues on the surface of the beans that have not fallen off in time, and the oils released from the beans will also adhere to the silver flakes. A large amount of silver skin on the surface of the beans will still produce irritating smoke under the influence of high temperature, which will be absorbed by the beans and affect the flavor of the coffee beans. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies where, during prolonged high-temperature roasting, a large amount of silverskin residue remains on the surface of the bean skin, producing irritating fumes that are absorbed by the bean and affect its flavor.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a coffee bean roaster, comprising an oven-integrated cage and a feeding box, wherein a hollow rotating ring is rotatably connected to the inner sides of both ends of the oven-integrated cage, and a triangular support member is rotatably connected inside the hollow rotating ring, a gas guide support pipe is fixedly connected between the two hollow rotating rings, a movable plate is slidably installed on the gas guide support pipe, a guide suction pipe is installed on the gas guide support pipe, a guide suction groove is formed through the interior of the movable plate, a filter pipe is installed on the triangular support member, the filter pipe is connected to the gas guide support pipe, the movable plate can also be snapped onto the oven-integrated cage, and a planetary gear transmission set is provided between the oven-integrated cage, the triangular support member and the hollow rotating ring; It also includes several brushes mounted on the movable plate; An upper snap-fit ​​component installed inside the movable plate to engage the movable plate with the hollow rotating ring of the interlayer; The separate lower snap-fit ​​component is set on the movable plate and the oven's inner cage to snap the movable plate and the oven's inner cage together. Adjust the pull-out mechanism that provides power to the engagement between the movable plate, the air guide support tube, and the oven's internal cage.

[0007] In at least some embodiments, the triangular support is provided with an air extraction port, and the hollow sandwich ring is provided with an air extraction hole. The triangular support is connected to the hollow sandwich ring through the air extraction port and the air extraction hole.

[0008] In at least some embodiments, the upper snap-fit ​​component is provided in at least two sets, the upper snap-fit ​​component includes a spring dome snap-fit ​​block and a concave snap-fit ​​groove, the spring dome snap-fit ​​block is disposed inside the movable plate, and at least two concave snap-fit ​​grooves are provided, the concave snap-fit ​​grooves are disposed on the outer side wall of the same guide suction pipe.

[0009] In at least some embodiments, the lower snap-fit ​​member is provided in a plurality of parts, and the lower snap-fit ​​member includes an elastic snap post and a transition post fixed to the inner wall of the oven's inner cage; It also includes a spherical plug-in head fixed to the bottom of the guide suction groove. Both sides of the spherical plug-in head are provided with guide limiting grooves, which are opened on the side of the movable plate near the inner wall of the oven's inner cage.

[0010] In at least some embodiments, two pull-out members are provided and are respectively provided at both ends of the oven's inner cage. Each pull-out member includes a telescopic rod fixedly installed on the oven's inner cage, and the output end of the telescopic rod extends into the interior of the oven's inner cage. A C-shaped pull-out plate fixed to the output end of the telescopic rod; A docking block is fixed to the outer wall of the movable plate, and the docking block is adapted to the C-shaped pull-out plate.

[0011] In at least some embodiments, the pull-out component further includes guide shallow rings, and multiple guide shallow rings are provided. The guide shallow rings and the hollow rotating ring are concentrically fixed to the inner wall of the oven's inner cage. The size of the guide shallow rings increases from the inside to the outside. Each guide shallow ring has a pull-out groove on its side wall that is adapted to the C-shaped pull-out plate. The C-shaped pull-out plate is slidably connected inside the pull-out groove. The guide shallow rings are used to guide the rotation of the docking block. The pull-out groove provides space for the C-shaped pull-out plate to slide the docking block within the oven's inner cage.

[0012] In at least some embodiments, the planetary gear transmission assembly includes a plurality of fixed transmission gears fixedly mounted on a triangular support; an internal gear ring fixedly connected to one end of the oven's inner cage; and an external gear ring fixedly sleeved on the outer wall of the hollow rotating ring in the interlayer; all the fixed transmission gears are meshed with the internal gear ring and the external gear ring.

[0013] In at least some embodiments, the inner toothed ring is rotatably sealed to the side away from the oven's inner cage, and the sealing cover is fixedly mounted on the triangular support.

[0014] In at least some embodiments, the ports of the filter tubes are all equipped with movable filter cartridges, and the outer side of the oven's inner cage is provided with a side tube, and the filter tubes are all fixedly connected to the side tubes. There are two side tubes, and one of the two filter tubes is selected to be connected to the other side tube. Side guide rollers are rotatably installed on the outer side wall of each side tube.

[0015] In at least some embodiments, a support rail is fixedly connected between the two triangular support members. The support rail guides the material box when it is inserted into the oven's inner cage and provides support for the material box.

[0016] Compared with the prior art, the advantages and positive effects of the present invention are as follows: In this invention, by setting a planetary gear transmission group, when the oven's inner cage rotates, the hollow rotating ring of the interlayer rotates relative to the oven's inner cage. The movable plate can then use a brush to comb the surface of the beans inside the oven's inner cage to help the silver skin detach from the beans. By setting an upper locking part, a lower locking part, and a pull-out part, one end of the movable plate can be controlled to be close to the inner wall of the oven's inner cage. The brush, close to the inner wall of the oven's inner cage, is squeezed and spreads outwards, and can be directly inserted into the bean pile. This allows the brush to not only clean the silver skin on the surface of the beans, but also to clean the silver skin adhering to the inner wall of the oven's inner cage at the same time. By setting up a hollow rotating ring with a sandwich structure, an air guide support pipe, and a guide air extraction pipe, the movable plate drives the guide air extraction groove to be inserted into the coffee bean pile, which is closer to the bean body to extract the smoke, while also extracting the silver dust cleaned by the brush. Alternatively, the movable plate can be pulled out and engaged with the inner wall of the oven's inner cage via the lower locking mechanism. This allows the movable plate to detach from the guide exhaust pipe and rotate with the oven's inner cage. Since the dispensing box is fixed, as the movable plate rotates from below to above the dispensing box, it gradually tilts towards the box to guide the coffee beans into it. After removing the dispensing box, the roasted coffee beans can be taken out, making dispensing and retrieval convenient. Attached Figure Description

[0019] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Implementation examples, based on Figures 1-9 ,like Figure 1 As shown in the figure, an embodiment of the present invention provides a coffee bean roaster including an oven-integrated cage 1 and a feeding box 11. Both ends of the oven-integrated cage 1 are rotatably connected to hollow rotating rings 3. Triangular support members 2 are rotatably connected inside each hollow rotating ring 3. An air guide support pipe 31 is fixedly connected between the two hollow rotating rings 3. A movable plate 4 is slidably mounted on the air guide support pipe 31. A guide suction pipe 32 is installed on the air guide support pipe 31. A guide suction groove 33 is formed through the interior of the movable plate 4. A filter pipe 21 is installed on the triangular support member 2. The filter pipe 21 and... The air guide support pipe 31 is connected, and the movable plate 4 can also be snapped onto the oven's inner cage 1. A planetary gear transmission group 5 is provided between the oven's inner cage 1, the triangular support 2, and the hollow rotating ring 3. It also includes several brushes 41 installed on the movable plate 4; an upper snap-fit ​​component 42 installed inside the movable plate 4 for movably snapping the movable plate 4 onto the hollow rotating ring 3; a lower snap-fit ​​component 43 separately installed on the movable plate 4 and the oven's inner cage 1 for snapping the movable plate 4 onto the oven's inner cage 1; and a pull-out component 44 that provides power for adjusting the snap-fit ​​between the movable plate 4 and the air guide support pipe 31 and the oven's inner cage 1.

[0022] like Figure 4 , Figure 7 and Figure 8In the process, the triangular support member 2 is provided with an air extraction port 24, and the hollow rotating ring 3 is provided with an air extraction hole 34. The triangular support member 2 is connected to the hollow rotating ring 3 through the air extraction port 24 and the air extraction hole 34. When the air extraction device is connected to the outside of the filter tube 21, the movable plate 4 and the oven inner cage 1 are in a rotating state, and air can still be extracted from the air guide support tube 31 through the air extraction port 24 and the air extraction hole 34. The air guide support tube 31 can extract air from the oven inner cage 1 through the guide air extraction groove 33, and can directly extract silver dust and smoke from the bean pile.

[0023] like Figure 4 and Figure 6 In this configuration, at least two sets of upper locking members 42 are provided. Each upper locking member 42 includes a spring dome locking block 4201 and an inner recessed locking groove 4202. The spring dome locking block 4201 is disposed inside the movable plate 4, and at least two inner recessed locking grooves 4202 are provided. The inner recessed locking grooves 4202 are disposed on the outer side wall of the same guide suction pipe 32. When the movable plate 4 slides along the guide suction pipe 32 through the guide suction groove 33, and when the external force of the pull-out member 44 pushes and pulls, the movable plate 42 can be pushed and pulled. Pulling the spring dome latch 4201 removes it from the concave groove 4202, and when the spring dome latch 4201 moves to the next concave groove 4202, it actively engages, thus positioning and limiting the position of the movable plate 4 on the guide suction pipe 32. The concave groove 4202 is closed on the guide suction groove 33, so that the guide suction pipe 32 remains sealed when inserted into the guide suction groove 33, ensuring that the bottom of the guide suction groove 33 still has the conditions for continuous suction when the movable plate 4 slides on the guide suction pipe 32.

[0024] like Figure 3 and Figure 5 In the process, the lower locking member 43 is provided with several parts. The lower locking member 43 includes an elastic locking post 4301 and a transition post 4304 fixed to the inner wall of the oven's inner cage 1; it also includes a spherical insertion head 4302 fixed to the bottom of the guide suction groove 33. The spherical insertion head 4302 has guide limiting grooves 4303 on both sides. The guide limiting grooves 4303 are opened on the side of the movable plate 4 near the inner wall of the oven's inner cage 1. The transition post 4304 is adapted to the guide suction groove 33. Before the movable plate 4 separates from the guide suction pipe 32, the transition post 4304... 04 can be inserted into the guide suction groove 33 in advance to guide the movement of the movable plate 4. After the elastic locking post 4301 is engaged with the top of the guide limiting groove 4303, the transition post 4304 is fully inserted into the guide suction groove 33. After the movable plate 4 is engaged with the oven inner cage 1, it separates from the guide suction pipe 32. As the oven inner cage 1 rotates, the movable plate 4 isolates and lifts the bean pile on one side. As the movable plate 4 gradually tilts to guide the bean pile into the feeding box 11, the transition post 4304 can always provide support for the movable plate 4.

[0025] like Figure 3 and Figure 8 In this oven, two pull-out components 44 are provided and respectively located at both ends of the oven's inner cage 1. Each pull-out component 44 includes a telescopic rod 4401 fixedly installed on the oven's inner cage 1, with the output end of the telescopic rod 4401 extending into the interior of the oven's inner cage 1; a C-shaped pull-out plate 4402 fixedly connected to the output end of the telescopic rod 4401; and a connecting block 4403 fixedly connected to the outer wall of the movable plate 4. The connecting block 4403 is adapted to the C-shaped pull-out plate 4402. As the movable plate 4 rotates, the C-shaped pull-out plate 4402 rotates with the oven's inner cage 1. After the connecting block 4403 enters the interior of the C-shaped pull-out plate 4402, the telescopic rod 4401 is activated to control the C-shaped pull-out plate 4402 to perform a pulling action. Pulling the connecting block 4403 can drive the movable plate 4 to perform a pulling action on the guide suction pipe 32, providing power for the sliding of the movable plate 4 on the guide suction pipe 32 and for the movable plate 4 to engage with the oven's inner cage 1. The pull member 44 also includes guide shallow rings 4404, of which multiple guide shallow rings 4404 are provided. Each guide shallow ring 4404 is concentrically fixed to the inner wall of the oven's inner cage 1 along with the sandwich hollow rotating ring 3. The size of the guide shallow rings 4404 increases sequentially from the inside to the outside. Each guide shallow ring 4404 has a pull groove 4405 on its side wall that matches the C-shaped pull plate 4402. The C-shaped pull plate 4402 is slidably connected inside the pull groove 4405. 404 is used to guide the rotation of the docking block 4403. The pull-out groove 4405 provides space for the C-shaped pull-out plate 4402 to drive the docking block 4403 to slide within the oven's inner cage 1. During the rotation of the docking block 4403, it moves along the shallow guide rings 4404 on both sides. The shallow guide rings 4404 not only provide guidance for the sliding of the docking block 4403, but also effectively prevent the movable plate 4 from actively detaching from the guide exhaust pipe 32 and from the oven's inner cage 1.

[0026] As in examples seven and eight, the planetary gear transmission assembly 5 includes several fixed transmission gears 51 fixedly mounted on the triangular support 2; an internal gear ring 52 fixedly connected to one end of the oven's inner cage 1; and an external gear ring 53 fixedly sleeved on the outer wall of the hollow rotating ring 3. All the fixed transmission gears 51 are meshed with the internal gear ring 52 and the external gear ring 53. When the fixed transmission gears 51 are connected to an external drive component, they can simultaneously drive the internal gear ring 52 and the external gear ring 53 to rotate, that is, drive the oven's inner cage 1 and the hollow rotating ring 3 to rotate. Figure 1 In the process, the inner gear ring 52 is rotatably connected to a sealing cover 54 on the side away from the oven's inner cage 1. The sealing cover 54 is fixedly mounted on the triangular support 2, providing sealing protection for each transmission component in the planetary gear transmission group 5; such as Figure 1 and Figure 9 In this process, each port of the filter tube 21 is equipped with a movable filter cartridge 2101, which can filter silver dust and facilitate cleaning. A side tube 22 is provided on the outside of the oven's inner cage 1, and the filter tubes 21 are all fixedly connected to the side tube 22. There are two side tubes 22, and the two filter tubes 21 can be connected to one of the side tubes 22. A side guide roller 2201 is rotatably installed on the outer wall of each side tube 22, which can simultaneously draw air out of the two filter tubes 21 through the same side tube 22. It can still be used when one movable filter cartridge 2101 is blocked. A support rail 23 is fixedly connected between the two triangular support members 2. The support rail 23 guides the material box 11 when it is inserted into the oven's inner cage 1 and provides support for the material box 11.

[0027] In this embodiment, the active rotation of the fixed transmission gear 51 drives the internal gear ring 52 and the external gear ring 53 to rotate, so that the hollow rotating ring 3 of the sandwich layer rotates relative to the oven cage 1 during the rotation process. After the side guide roller 2201 connected to the filter pipe 21 is connected to the external air extraction device, the filter pipe 21 is connected to the air guide support pipe 31 through the air extraction port 24 and the air extraction hole 34, thereby extracting the air from the movable plate 4 close to the oven's inner cage 1 through the guide air extraction pipe 32 and the guide air extraction groove 33, and extracting the smoke and silver dust during the baking process. In the early stage of roasting, the upper snap-fit ​​part 42 on the movable plate 4 snaps into the position close to the air guide support tube 31. During the relative rotation of the movable plate 4 and the oven inner cage 1, the brush 41 combs the coffee bean pile at the bottom of the oven inner cage 1, so that the bean pile is reasonably distributed at the bottom of the oven inner cage 1, and combs the debris on the surface of the bean, and extracts it through the guide air extraction groove 33. During the middle and later stages of baking, after the docking block 4403 rotates into the C-shaped pull plate 4402, the telescopic rod 4401 is activated to pull the docking block 4403 using the C-shaped pull plate 4402. This first causes the spring dome locking block 4201 to disengage from the current concave slot 4202. Then, the movable plate 4 slides along the outer wall of the guide suction pipe 32 through the guide suction groove 33 until the spring dome locking block 4201 is engaged in the next concave slot 4202, and the docking block 4403 enters between the two guide shallow rings 4404 of the outer ring. The brush 41 presses against the inner wall of the oven's inner cage 1, and the bristles deform and expand outwards from the inner wall of the oven's inner cage 1. At this time, the movable plate 4 can not only move along the outer ring 4403 through the docking block 4403 but also... 404 rotates stably, and the brush 41 inserts its bristles into the bean pile. During the continuous rotation of the hollow rotating ring 3 and the oven's inner cage 1, it helps to clean the residual silver dust on the surface of the beans and the silver dust adhering to the inner wall of the oven's inner cage 1. During the long-term high-temperature roasting process, the brush 41 applies external force to help clean the large amount of debris remaining on the beans. The movable plate 4 is inserted into the bean pile, which not only helps to stir-fry the coffee beans, but also guides the bottom of the exhaust duct 33 to directly extract the smoke close to the surface of the beans, avoiding the large amount of smoke generated from the beans from mixing and staying in the bean pile for a long time. It also continuously extracts the silver dust on the surface of the beans and the silver dust adhering to the inner surface of the oven's inner cage 1, reducing the impact of the smoke generated by the beans and the smoke generated by the silver dust on the flavor of the coffee beans. After baking, when unloading is required, after the connecting block 4403 enters the pull-out groove 4405, the movable plate 4 is pulled closer to the oven's inner cage 1 by the spring dome locking block 4201. The spring dome locking block 4201 first disengages from the original concave groove 4202, and then the movable plate 4 continues to slide on the guide suction pipe 32 through the guide suction groove 33, so that the bottom end of the guide suction groove 33 gradually inserts into the transition post 4304. As the spherical insertion head 4302 approaches the inner wall of the oven's inner cage 1, its bottom arc surface abuts against the lower elastic locking posts 4301 on both sides, causing the elastic locking posts 4301 to deform and bend to both sides, expanding the gap. When the spherical insertion head 4302 enters the elastic locking post 4301... After the elastic locking post 4301 is reset, it is locked in the guide limiting groove 4303 and the end slot of the ball-shaped insertion head 4302. This allows the guide suction groove 33 to be disengaged from the guide suction pipe 32 and inserted into the outside of the transition post 4304. This allows the movable plate 4 to be locked onto the inner wall of the oven's inner cage 1. As the oven's inner cage 1 continues to rotate, the bean pile will always converge towards the bottom of the oven's inner cage 1 due to gravity. The movable plate 4 intercepts the bean pile and gradually increases the tilt angle as it rises above the feeding box 11. This guides the bean pile on one side of the movable plate 4 to slide into the lower feeding box 11. After feeding is completed, the coffee beans can be taken out by pulling out the feeding box 11. Feeding and taking out the beans is convenient.

[0028] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
