[0002] As one of the world's three major beverages, coffee is increasingly popular and increasingly associated with fashion and modern lifestyles. Raw coffee beans themselves lack any aroma; only after they are roasted can their rich coffee flavor be detected. Therefore, roasting coffee beans is a process that transforms their internal components. Only after roasting, when the components that release the coffee aroma are produced, can we smell the aroma. To improve roasting efficiency, roasting machines are commonly used in the prior art. Among the existing patents, the Chinese patent document with application number 201610067785.3 discloses a semi-direct fire and semi-hot air coffee bean roaster and a roasting method thereof, comprising a bottom bracket, a silver skin collector, a notch regulating valve, a funnel, a drum, a driving device, a fire grate, a base and a cooling device. The silver skin collector is arranged on the bottom bracket and connected to the funnel through the notch regulating valve. The unloading exhaust is arranged at the upper end of the drum. The drum is arranged at the upper end of the base through the driving device. The fire grate is arranged below the drum. The cooling device is arranged on one side of the base. It is characterized in that: the drum includes a simplified body, a lower stirring blade, a center ring, a support rod and an upper stirring blade. The lower stirring blade and the upper stirring blade are evenly distributed on the inner wall surface of the drum. The center ring is fixedly connected to the drum by a support rod. The rear end of the drum has a rear cone, and the rear cone has a mesh. The notch regulating valve includes an outer wall, a valve core, a valve core rod and a valve port. The valve core is arranged in the outer wall and fixedly connected to the valve core rod. The valve port is arranged on one side of the outer wall and communicates with the funnel. The patent document uses a semi-direct fire and semi-hot air method to roast coffee beans, which improves the roasting efficiency. However, its structure is not compact enough and is large in size, which takes up a lot of space. Therefore, the drawback is very obvious and a solution is urgently needed. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to facilitate understanding by those skilled in the art, the present invention is further described below with reference to embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention.

[0024] like Figures 1 to 5As shown, the utility model provides a horizontal coffee bean hot air roaster, which includes a machine platform 1, a left support plate 2 and a right support plate 3 relatively arranged on the machine platform 1, a roasting and stirring shaft 4 rotatably connected between the left support plate 2 and the right support plate 3, a roasting cylinder 5 installed between the left support plate 2 and the right support plate 3 and sleeved on the roasting and stirring shaft 4, a rotation driving mechanism 6 installed on the machine platform 1 and used for driving the roasting and stirring shaft 4 to rotate, a hot air mechanism 7 installed on the machine platform 1, a coffee bean supply mechanism 8 installed on the top of the machine platform 1, a discharge opening and closing mechanism 9 installed on one side of the machine platform 1 and an exhaust and silver skin removal mechanism 10 installed on the other side of the machine platform 1; the roasting cylinder 5, the left support plate 2 and the right support plate 3 enclose a roasting chamber, the side edge of the roasting and stirring shaft 4 is in sliding contact with the inner wall of the roasting cylinder 5, and a discharge bin 1 is provided on both sides of the machine platform 1. 1 and a silver skin collection bin 12, the left support plate 2 is provided with a hot air hole 13 and a discharge hole 14, the discharge hole 14 is located at the bottom of the left support plate 2, the height of the hot air hole 13 is higher than the height of the discharge hole 14, the air outlet end of the hot air mechanism 7 is connected with the roasting chamber via the hot air hole 13, the discharge opening and closing mechanism 9 is used to open or close the discharge hole 14, the discharge hole 14 is connected with the discharge bin 11 via the discharge opening and closing mechanism 9, the top of the right support plate 3 is provided with a feed hole 15 and an exhaust and silver skin removal hole 16, the discharge end of the coffee bean feeding mechanism 8 is connected with the roasting chamber via the feed hole 15, the exhaust and silver skin removal hole 16 is connected with the roasting chamber, the exhaust and silver skin removal hole 16 is connected with the silver skin collection bin 12 via the exhaust and silver skin removal mechanism 10, the exhaust and silver skin removal mechanism 10 is used to exhaust outward and collect the silver skin into the silver skin collection bin 12; the axis of the roasting cylinder 5 is arranged horizontally.

[0025] In actual application, the coffee bean supply mechanism 8 supplies the coffee beans to be roasted into the roasting chamber, and the hot air mechanism 7 introduces hot air into the roasting chamber, and the hot air roasts the coffee beans in the roasting chamber. At the same time, the rotation drive mechanism 6 drives the roasting stirring shaft 4 to rotate, and the rotating roasting stirring shaft 4 rotates in the roasting chamber and stirs the coffee beans in the roasting chamber. During the rotation of the roasting stirring shaft 4, since the side of the roasting stirring shaft 4 slides in contact with the inner wall of the roasting cylinder 5, the roasting stirring shaft 4 can lift (stir) the coffee beans and then drop them to the bottom of the roasting cylinder 5, and under the action of the hot air, the coffee beans roll in the roasting chamber, and the silver skin produced during roasting will be blown away by the hot air and the exhaust silver skin removal mechanism 10. The coffee beans are then passed through the roasting chamber and the coffee is ... When the roasting time reaches the preset time, the hot air mechanism 7 stops working, and the roasting stirring shaft 4 continues to rotate, so that the roasting stirring shaft 4 drives the coffee beans to the position of the discharge hole 14. At this time, the discharge opening and closing mechanism 9 opens the discharge hole 14, and the roasted coffee beans are discharged into the discharge bin 11 through the discharge hole 14 to realize the discharge of the coffee beans. The structure of the present invention is compact and the layout is reasonable. It is small in size. It can not only roast the coffee beans evenly and with good roasting quality, but also automatically collect the silver skin. Compared with the vertical coffee bean roaster in the prior art, the roasting amount of coffee beans is limited to avoid excessive load on the stirring shaft, so that the number of roasted coffee beans is small. The present application adopts a horizontal structure to roast the coffee beans, which can increase the number of roasted coffee beans.

[0026] In this embodiment, a first accommodating chamber 17 and a second accommodating chamber 18 are respectively provided on either side of the machine 1. The first accommodating chamber 17 is located above the discharge bin 11, and the second accommodating chamber 18 is located above the silver scale collection bin 12. The discharge opening and closing mechanism 9 is located in the first accommodating chamber 17, and the silver scale exhaust and removal mechanism 10 is located in the second accommodating chamber 18. This structural design makes the machine compact, rationally arranged, and small in size.

[0027] In this embodiment, the roasting and stirring shaft 4 includes a rotating shaft 19 rotatably connected to the left support plate 2 and the right support plate 3, a connecting plate 20 connected to the middle of the rotating shaft 19, and a plurality of stirring blades 21 arranged along the length of the connecting plate 20. The stirring blades 21 are wavy in shape, with the connecting plate 20 perpendicular to the rotating shaft 19, the rotating shaft 19 being arranged horizontally, and the stirring blades 21 intersecting the connecting plate 20. This structural design facilitates sufficient stirring of the coffee beans in the roasting chamber, resulting in more uniform roasting of the coffee beans.

[0028] In this embodiment, two adjacent stirring blades 21 are arranged crosswise. When the stirring blades 21 rotate along the R direction to a horizontal position, since the height of the end of the stirring blade 21 that stirs the coffee beans close to the discharge hole 14 is lower than the height of the end away from the discharge hole 14, the coffee beans stirred by the stirring blades 21 will be guided by the stirring blades 21 to fall to the position of the discharge hole 14, which is not only beneficial to the cyclic tumbling of the coffee beans during roasting, but also beneficial to the discharge of the roasted coffee beans.

[0029] In this embodiment, the discharge opening and closing mechanism 9 includes a discharge pipe 22 installed between the feed port of the discharge bin 11 and the discharge hole 14, an opening and closing sleeve 23 that is lifted and slidably sleeved outside the discharge pipe 22, a manual handle 24 connected to the opening and closing sleeve 23, and an electric control component 25 arranged between the machine 1 and the outer wall of the opening and closing sleeve 23. The electric control component 25 is used to drive the opening and closing sleeve 23 to lift and slide, and the opening and closing sleeve 23 is used to open or close the discharge hole 14.

[0030] In actual use, a roasting time is set. When the roasting time is up, the electronic control component 25 automatically controls the opening and closing sleeve 23 to descend, causing the opening and closing sleeve 23 to open the discharge hole 14. The roasted coffee beans are discharged from the discharge hole 14 and fall into the discharge bin 11 through the discharge pipe 22. When the electronic control component 25 is not working or when manual control of the discharge of the roasted coffee beans is desired, the manual control handle 24 is pulled down, causing the manual control handle 24 to drive the opening and closing sleeve 23 to descend and open the discharge hole 14. The roasted coffee beans can then move along the discharge hole 14 and the discharge pipe 22 into the discharge bin 11. When the discharge hole 14 needs to be closed, the manual control handle 24 is pushed upward to drive the opening and closing sleeve 23 to ascend, or the electronic control component 25 controls the opening and closing sleeve 23 to ascend, causing the opening and closing sleeve 23 to close the discharge hole 14.

[0031] In this embodiment, the electronic control assembly 25 includes a rack 26 mounted on the outer wall of the opening and closing sleeve 23, a rotary actuator 28 mounted on the machine platform 1 or the left support plate 2, and a gear 27 mounted on the rotating end of the rotary actuator 28. The gear 27 is in driving engagement with the rack 26. Specifically, the rotary actuator 28 can be a motor. In actual use, the rotary actuator 28 drives the gear 27 to rotate. The rotating gear 27 engages with the rack 26 to drive the rack 26 and the opening and closing sleeve 23 to move upward and downward, thereby enabling the opening and closing sleeve 23 to open or close the discharge port 14.

[0032] In this embodiment, an upper trigger block 29 is provided on the top side of the rack 26, and a lower trigger block 30 is provided on the bottom side of the rack 26. The left support plate 2 is equipped with an upper limit switch 31 and a lower limit switch 32. The upper limit switch 31 is located above the lower limit switch 32. The rack 26 is raised and lowered between the upper limit switch 31 and the lower limit switch 32. The upper trigger block 29 is used to trigger the upper limit switch 31, and the lower trigger block 30 is used to trigger the lower limit switch 32. The upper limit switch 31 and the lower limit switch 32 are respectively electrically connected to the rotation driver 28.

[0033] In actual application, when the upper trigger block 29 conflicts with the upper limit switch 31, it proves that the opening and closing sleeve 23 closes the discharge hole 14. At this time, the upper limit switch 31 feeds back a signal to the rotation driver 28, causing the rotation driver 28 to stop working; when the lower trigger block 30 conflicts with the lower limit switch 32, it proves that the opening and closing sleeve 23 opens the discharge hole 14. At this time, the lower limit switch 32 feeds back a signal to the rotation driver 28, causing the rotation driver 28 to stop working.

[0034] In this embodiment, the left support plate 2 and / or the right support plate 3 are provided with sampling holes, into which a sampler 33 is detachably inserted. The sampler 33 is rotatable relative to the sampling hole, and a material receiving trough is recessed at the inner end of the sampler 33, which is capable of extending into the roasting chamber. During the roasting process, the opening of the material receiving trough of the sampler 33 faces downward. When it is necessary to understand the real-time roasting status of the coffee beans, the sampler 33 is rotated so that the opening of the material receiving trough of the sampler 33 faces upward, and the stirred coffee beans enter the material receiving trough. The sampler 33 is then removed from the sampling hole, and the roasted coffee beans can be observed and smelled, which is conducive to understanding the roasting status of the coffee beans in real time.

[0035] In this embodiment, the coffee bean feeding mechanism 8 includes a feed pipe 34 installed on the outer wall of the right support plate 3 and connected to the feed hole 15, a funnel 35 installed on the machine 1 and used to communicate with the feed port of the feed pipe 34, and a push-pull plate 36 that is translated on the machine 1 and located between the feed port of the feed pipe 34 and the discharge port of the funnel 35. The push-pull plate 36 is used to open or close the discharge port of the funnel 35 and / or the feed port of the feed pipe 34.

[0036] In actual application, a certain amount of coffee beans to be roasted is poured into the funnel 35. When coffee beans need to be supplied to the roasting chamber, the push-pull plate 36 is pulled outward so that the push-pull plate 36 opens the discharge port of the funnel 35 or the feed port of the feed pipe 34, and the coffee beans in the funnel 35 enter the roasting chamber through the feed pipe 34 to realize the feeding of the coffee beans; when the feeding is completed, the push-pull plate 36 is pushed inward so that the push-pull plate 36 closes the discharge port of the funnel 35 or the feed port of the feed pipe 34.

[0037] Specifically, the exhaust and silver scale removal mechanism 10 can be a cyclone dust collector, which can separate the baking gas and silver scale, so as to discharge the baking gas and collect the silver scale into the silver scale collection bin 12. Preferably, the cyclone dust collector can adopt an existing structure, which will not be described in detail here.

[0038] In this embodiment, the roasting cylinder 5 is a transparent cylinder, preferably a heat-resistant glass cylinder. A transparent shield 37 is installed between the left support plate 2 and the right support plate 3. The transparent shield 37 is disposed outside the roasting cylinder 5. The transparent shield 37 protects the roasting cylinder 5. During roasting, the operator can observe the roasting status and roasting degree of the coffee beans in the roasting chamber in real time through the transparent shield 37 and the transparent roasting cylinder 5.

[0039] In this embodiment, the discharge bin 11 is detachably connected to a discharge box 38, and the shavings collection bin 12 is detachably connected to a collection box 39. The discharge box 38 facilitates the removal of roasted coffee beans and cleaning; the collection box 39 facilitates the removal of shavings and cleaning.

[0040] Specifically, the machine 1 is equipped with a housing 40, which covers the first and second accommodating chambers 17 and 18. The outer ends of the funnel 35, the sampler 33, the manual handle 24, and the push-pull plate 36 are exposed outside the housing 40. This structural design covers and protects the internal structures of the machine (such as the exhaust and silver removal mechanism 10), resulting in an aesthetically pleasing, complete, and concise appearance.

[0041] All technical features in this embodiment can be freely combined according to actual needs.

[0042] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
