In an example where the infrared imaging module and the visible light imaging module are used to simultaneously image the coffee beans in the roasting chamber, the processing component can match the imaging of the two modules, thereby displaying real-time images and temperatures of the coffee beans in different areas on the display screen, allowing the user to understand the roasting status of the coffee beans in the roasting chamber in real time. If the infrared imaging module directly images the interior of the roasting chamber for temperature measurement, if the temperature of the roasting chamber surface within the field of view is higher than the temperature of the coffee beans, the temperature of the coffee beans measured by the infrared imaging module will be affected by the temperature of the roasting chamber surface. In the embodiment of the present application, the coffee beans are concentrated and covered as much as possible at the observation window by setting the observation window, reducing the area of ​​the roasting chamber inner surface appearing in the infrared image, making the temperature measured by the infrared imaging module closer to the temperature of the coffee beans, and improving the accuracy of the coffee bean temperature measurement.

[0084] like Figure 1 As shown, Figure 1 1 is a schematic diagram of an embodiment of a partial structure of a coffee bean roasting device of the present application. The coffee bean roasting device 10 includes a roasting chamber 11 for carrying coffee beans and a roasting assembly 12 for roasting the coffee beans in the roasting chamber 11. An observation window 111 is provided on the inner wall of the roasting chamber 11. Figure 2As shown, Figure 2 The figure is an exploded schematic diagram of an embodiment of the partial structure and imaging assembly of the coffee bean roasting device of the present application. The coffee bean roasting device 10 also includes an imaging assembly 13 fixed to the outside of the roasting chamber 11. Optionally, the imaging assembly is removably fixed to the outside of the roasting chamber. Various methods of removable fixing are available. For example, the coffee bean roasting device 10 also includes a main structural member 14, within which the roasting chamber 11 is fixed. The main structural member 14 is also provided with a snap structure, a threaded structure, or other fixing structure. The imaging assembly 13 is removably fixed to the main structural member 14 via this snap structure, threaded structure, or other fixing structure, thereby securing the imaging assembly 13 and the roasting chamber 11 to each other. Since the imaging assembly images the roasting chamber through an observation window, it is necessary to keep the observation window clean. The imaging assembly is removably fixed to the roasting chamber, allowing the user to easily remove the imaging assembly to clean the observation window.

[0085] Some examples, such as Figure 3 As shown, Figure 3 FIG1 is a schematic cross-sectional view of an embodiment of the imaging assembly of the present application. The imaging assembly 13 includes an infrared imaging module 131 for performing infrared imaging of the coffee beans in the roasting chamber through the observation window 111 to obtain the temperature of the coffee beans in the roasting chamber.

[0086] In some examples, the imaging assembly 13 further includes a visible light imaging module 132 for imaging the coffee beans in the roasting chamber through the observation window 111 to obtain a visible light image of the coffee beans in the roasting chamber. Optionally, the imaging assembly 13 includes an infrared imaging module 131 and a visible light imaging module 132 arranged side by side, and the field of view (FOV) of the infrared imaging module 131 and the field of view of the visible light imaging module 132 at least partially overlap. The imaging assembly 13 is located outside the observation window 111, and the infrared imaging module 131 and the visible light imaging module 132 respectively simultaneously image the coffee beans in the roasting chamber 11 through the observation window 111.

[0087] The coffee bean roasting apparatus further includes a processing component (not shown) configured to obtain temperature information of the coffee beans based on the infrared imaging provided by the infrared imaging module 13 and / or obtain image information of the coffee beans based on the visible light imaging provided by the visible light imaging module 132. For example, the image information may include RGB information, grayscale value information, texture information, or color value information of the coffee beans. The temperature information may include the temperature of the coffee beans, temperature differences between different coffee beans, or temperature variation information of the coffee beans.

[0088] like Figure 1As shown, the coffee bean roasting device 10 further includes a display screen 15 for displaying a real-time image and / or temperature of the coffee beans according to the image information and / or temperature information.

[0089] Beneficial effects of imaging components

[0090] In the example of imaging the coffee beans in the roasting bin through the visible light imaging module, the image of the coffee beans in the roasting bin can be presented in real time on the display screen. Compared with the prior art in which the user directly observes the coffee beans in the roasting bin and the roasting bin is blurred due to insufficient light in the roasting bin and the moving coffee beans, the user of this application can clearly and intuitively view the real-time image of the coffee beans in the roasting bin through the display screen.

[0091] In the example of imaging coffee beans in a roasting chamber by an infrared imaging module, the coordinated structure causes the coffee beans to gather at the observation window, so that the temperature of the coffee beans can still be accurately measured when the amount of coffee beans is small. However, in the coffee bean roasting machine in the prior art, a probe is used for temperature measurement. When the amount of coffee beans is small, it is easy for the probe to fail to directly contact the coffee beans during the turning process, resulting in inaccurate temperature measurement. Alternatively, the coffee bean roasting machine in the prior art uses a single-point infrared temperature measurement, which is easy to be affected by the background temperature when the amount of coffee beans is small, resulting in inaccurate temperature measurement.

[0092] In the example of simultaneously imaging the coffee beans in the roasting bin by the infrared imaging module and the visible light imaging module, the processing component can match the imaging of the two modules, and then can display the real-time images and temperatures of the coffee beans in different areas on the display screen, so that the user can grasp the roasting status of the coffee beans in the roasting bin in real time. If the infrared imaging module directly images and measures the temperature inside the roasting bin, when the temperature of the inner surface of the roasting bin within the field of view is higher than the temperature of the coffee beans, the temperature of the coffee beans measured by the infrared imaging module will be affected by the temperature of the inner surface of the roasting bin. In the embodiment of the present application, by setting the observation window, the coffee beans are gathered as much as possible to cover the observation window, reducing the area of ​​the inner surface of the roasting bin appearing in the infrared image, so that the temperature measured by the infrared imaging module is closer to the temperature of the coffee beans, and the temperature measurement accuracy of the coffee beans is improved.

[0093] Optionally, the imaging assembly is located between the baking chamber and the display screen. Figure 1As shown, the main structural member 14 of the coffee bean roasting apparatus also includes a front panel 141. The display screen 15 is located on the front panel of the coffee bean roasting apparatus for direct user viewing. Optionally, the coffee bean roasting apparatus 10 is also provided with a physical operation panel, which is also located on the front panel to facilitate user operation. Alternatively, the coffee bean roasting apparatus 10 may be provided with a virtual operation panel on the display screen. This is not limited here. Optionally, a thermal insulation layer is provided on the side of the front panel 141 facing the roasting chamber 11 to prevent heat from the roasting chamber 11 from being transferred to the front panel. Optionally, this thermal insulation layer may be aerogel.

[0094] Alternatively, as Figure 1 and Figure 2 As shown, the imaging assembly 13 and cavity 16 are separated between the roasting chamber 11 and the front panel 141. Optionally, thermal insulation material is also placed between the roasting chamber 11 and the front panel 141. Compared to the prior art, where the roasting chamber is positioned on the surface of the coffee bean roasting equipment to allow the user to see the roasting chamber with the naked eye, resulting in a hot front panel, the imaging assembly and cavity between the roasting chamber and the display screen in the present embodiment significantly reduce heat transfer from the roasting chamber to the front panel, preventing the front panel from being hot and improving the user experience.

[0095] Some examples, such as Figure 3 As shown, the imaging assembly 13 also includes a housing 133, which is generally hollow and cylindrical. The interior of the housing 133 includes a bottom surface 1331 and an opening 1332 facing each other, as well as a side wall 1333 connecting the bottom surface and the opening. The infrared imaging module 131 and / or the visible light imaging module 132 are arranged on the bottom surface 1331 and facing the opening 1332. The opening 1332 is covered with a transparent glass that can transmit visible light and / or infrared bands, which is used to seal the infrared imaging module 131 and / or the visible light imaging module 132 inside the housing 133. For example, the transparent glass can transmit the far infrared band between 7 microns and 14 microns. When the imaging assembly is fixed to the baking chamber, the transparent glass and the observation window are opposite to each other, so that the infrared imaging module and / or the visible light imaging module can image the inside of the baking chamber.

[0096] Optionally, a groove 1334 is formed on the side wall of the housing for accommodating a fill light assembly 1335. The fill light assembly 1335 is located outside the field of view of the infrared imaging module 131 and the visible light imaging module 132, and the angle between the light-emitting surface and the optical axis of the visible light imaging module is less than 90 degrees. This prevents the light emitted by the fill light assembly from being directly reflected by the transparent glass onto the two imaging modules, causing interference light. Optionally, at least two grooves are formed on the side wall of the housing, each for accommodating a fill light assembly. Alternatively, an annular groove is formed on the side wall of the housing, surrounding the optical path of the infrared imaging module 131 and / or the visible light imaging module 132. At least two fill light assembly groups are distributed within this annular groove. Optionally, a light diffuser may be provided in the light path of the fill light assembly to ensure more uniform light output. Optionally, a fan (not shown) is provided within the housing of the imaging assembly to dissipate heat within the housing.

[0097] Since the coffee beans are in a state of continuous motion during the roasting process, optionally, the visible light imaging module in the imaging assembly includes a flying camera to be able to clearly image the moving coffee beans. Alternatively, the visible light imaging module includes a rolling camera or a global camera. In the example where the visible light imaging module includes a rolling camera, the rolling camera includes multiple rows of pixels for sequential exposure, and the fill light group is used to emit light beams within the intersection of the exposure times of the multiple rows of pixels. Specifically, each pixel row starts to be exposed at a different starting time in sequence, where t1 to t2 is the common exposure period of all pixel rows, and the fill light group is controlled to turn on between t1 and t2, so that the rolling camera can clearly image the moving object. In this way, the effect of a flying camera can be achieved with a rolling camera. Since the price of a rolling camera is generally lower than that of a flying camera, the use of a rolling camera in combination with a fill light group can achieve clear motion imaging at a low cost.

[0098] Optionally, in the example where the roasting assembly includes a halogen lamp, the control assembly is further configured to control the halogen lamp to turn on between t1 and t2 and off at other times to prevent the light emitted by the halogen lamp from affecting the rolling shutter camera. Alternatively, a light shield is fixed to the observation window within the roasting chamber to block the light beam from the halogen lamp from outside the observation window. The roasting chamber is stationary and further includes a stirring member for stirring the coffee beans. The light shield is configured to avoid the movement trajectory of the stirring member.

[0099] There are various ways to set up the baking chamber and baking components. Figure 4 It is a cross-sectional schematic diagram from one perspective of an embodiment of a partial structure of the coffee bean roasting equipment of the present application. Figure 5 : is a cross-sectional schematic diagram of another perspective of an embodiment of a partial structure of the coffee bean roasting device of the present application. In some examples, such as Figure 4 and Figure 5 The roasting chamber 11 is cylindrical and includes a first bottom surface 112 and a second bottom surface 113 that extend vertically opposite each other, and a sidewall 114 connecting the first bottom surface 112 and the second bottom surface 113. A first rotating shaft 115 and a stirring member 116 connected to the first rotating shaft 115 are also provided within the roasting chamber 11. The stirring member 116 is driven by the first rotating shaft 115 to stir the coffee beans within the roasting chamber 11.

[0100] like Figure 5 As shown, the observation window 111 is located on the lower half of the first bottom surface 112. The imaging component ( Figure 1 The imaging module (not shown) is located outside the first bottom surface, and the opening in the housing of the imaging module covers the observation window 111, so that the coffee beans in the roasting chamber at the observation window 111 can be imaged. In this way, even when the number of coffee beans is small, the coffee beans will still accumulate at the observation window due to gravity, allowing the imaging module to still obtain the condition of the coffee beans in the roasting chamber.

[0101] Optionally, the first rotating shaft 115 is located on the central axis of the roasting chamber 11, and the stirring member 116 rotates in a vertical plane driven by the first rotating shaft 115 to move along the side wall to stir the coffee beans. Figure 4 and Figure 5 In the illustrated example, the roasting chamber 11 is fixed and stationary within the coffee bean roasting apparatus, while the stirring element moves. In some examples, the stirring element may be fixed to the inner wall of the roasting chamber, and the roasting chamber and the stirring element rotate together under the drive of the first rotating shaft to stir the coffee beans, although this is not a limitation.

[0102] Some examples, such as Figure 6 As shown, Figure 6 This is a schematic diagram of an embodiment of a first rotating shaft and a stirring member within the roasting chamber of the coffee bean roasting apparatus of the present application. The stirring member 116 includes a plurality of paddles 1161 fixedly connected to the first rotating shaft 115, with distal ends 11611 of the paddles 1161 being in the form of horizontal strips extending along the sidewall. Driven by the first rotating shaft 115, the paddles 1161 rotate, causing their distal ends to move along the sidewall.

[0103] Optionally, the surfaces of the ends 11611 of the multiple blades facing the direction of rotation are concavely curved. The concave curved surface design of the blade ends allows the blades to ensure that the coffee beans roll along the side walls when stirring the coffee beans, while reducing the possibility of thrown coffee beans getting stuck between the blades and the side walls. Optionally, the angle between the surface of each end 11611 facing the direction of rotation and the first bottom surface is less than 90 degrees, and the angle between the surface of the second bottom surface is greater than 90 degrees, so that the surface of each end 11611 facing the direction of rotation is inclined toward the first bottom surface. This allows the stirring blades to attract more coffee beans toward the first bottom surface while stirring the coffee beans. Because the observation window is set in the lower half of the first bottom surface, the coffee beans can gather toward the observation window under the action of the stirring member and gravity, allowing the imaging component to image more coffee beans in a single frame of image, and also improving the consistency of the distance between each coffee bean and the imaging component, thereby improving the accuracy of the property parameters of each coffee bean measured based on the imaging of the imaging component.

[0104] Optionally, the stirring member 116 also includes a first circular ring 1161 located at the periphery of the first bottom surface and a second circular ring 1162 located at the periphery of the second bottom surface, and the end 11611 of each blade is connected to the first circular ring and the second circular ring. The first circular ring 1161, the second circular ring 1162 and the blade 1161 rotate together under the drive of the first rotating shaft 115. By fixing the end of each blade with two circular rings, it is possible to prevent coffee beans from falling between one side of the end of the blade and a bottom surface of the roasting chamber, causing beans to get stuck, and further avoid deformation of the blades caused by beans getting stuck. Optionally, the two circular rings are made of metal, which can further increase the metal area in contact with the coffee beans and increase the heating surface of the coffee beans.

[0105] The stirring member may also be other structures, for example, Figure 7 As shown, Figure 7 Schematic diagram of another embodiment of the first rotating shaft and stirring member in the roasting chamber of the coffee bean roasting equipment of the present application. Figure 6 The difference is that the end 11611 of the blade 1161 in this example is in the shape of a straight bar.

[0106] Alternatively, as Figure 5 As shown, the lower edge of the observation window 111 on the first bottom surface 112 is located at a height on the first bottom surface 112 that is higher than the thickness of the first ring 1161 and the thickness of the blade tip 11611, so that the first ring 1161 and the blade tip 11611 cannot be detected by the imaging component at the observation window 111. This can reduce the bottom area of ​​the roasting chamber captured by the infrared imaging module through the observation window, so that the infrared imaging module can collect the temperature of the coffee beans as much as possible instead of the temperature of the inner wall of the roasting chamber.

[0107] Optionally, at least a portion of the surface of the baking chamber is covered with a heat-insulating material to reduce the impact of the heat of the baking chamber on other parts.

[0108] There are many types of roasting components in a coffee bean roasting device. In one example, Figure 4 As shown, a first through-hole area 117 is provided on the side wall of the roasting bin 11. The roasting assembly 12 includes a hot air pipe 121 located on a side outside the roasting bin 11, and a first heating module 122 and an air inlet fan 123 provided in the hot air pipe 121. Optionally, the first heating module may be a heating wire. One end of the hot air pipe 121 is provided with an opening 1211 facing the first through-hole area 117, and the air inlet motor 123 is used to blow the hot air generated by the first heating module 122 toward the first through-hole area 117 through the opening 1211, so that the hot air flows into the roasting bin 11 through the first through-hole area 117 to roast the coffee beans. To prevent the coffee beans from leaking out of the first through-hole area, the first through-hole area may optionally be provided with a plurality of small through-holes with a diameter smaller than the size of the coffee beans.

[0109] In some examples, a second through-hole area (not shown) is provided on the roasting chamber 11. The roasting assembly 12 includes a halogen lamp 124 provided on the outside of the second through-hole area. The heat generated by the halogen lamp 124 roasts the coffee beans in the roasting chamber through the second through-hole area. The halogen lamp adopts an infrared heating mode, which can heat the bean cores of the coffee beans. Optionally, the roasting assembly 12 can include both a hot air pipe and a halogen lamp. Combining these two heating methods can roast the coffee beans more comprehensively and better control the temperature difference between the surface and the bean core of the coffee beans.

[0110] Optionally, the second through-hole area and the halogen lamp are located at the top of the roasting chamber, and the coffee beans maintain a certain distance from the halogen lamp due to gravity, thereby avoiding burns to the coffee beans caused by long-term contact between the coffee beans and the halogen lamp. Figure 4 The second through-hole area is illustrated by a plane as an example. Optionally, the second through-hole area can be a curved surface, that is, the side wall of the roasting chamber is in the shape of a cylindrical side surface, so that the distance between the end of the paddle of the stirring member and the side wall of the roasting chamber is smaller, thereby reducing the situation where the stirring member gets stuck in the process of stirring coffee beans.

[0111] There are many ways to feed beans into the roasting chamber. In some examples, a bean inlet is provided on the roasting chamber. The bean inlet can be provided on the side wall or the first bottom surface or the second bottom surface. Figure 1 and Figure 8A As shown, Figure 8A yes Figure 1The schematic diagram of the coffee bean roasting device shown in another perspective. The roasting bin 11 is also provided with a bean inlet 118. The top of the coffee bean roasting device is also provided with a bean inlet trough 17, and a bean inlet channel 18 connecting the bean inlet 118 and the bottom surface 171 of the bean inlet trough 17. At least part of the bottom surface 171 of the bean inlet trough 17 is movable. After the user loads the coffee beans into the bean inlet trough, the bottom surface 171 of the bean inlet trough 17 can be driven manually or by a motor to connect the bean inlet trough and the bean inlet channel, so that the coffee beans in the bean inlet trough fall from the bean inlet channel and the bean inlet into the roasting bin under the action of gravity. Optionally, the bottom surface 171 of the bean inlet trough 17 can also be restored to its original state under manual or motor drive to separate the bean inlet trough and the bean inlet channel. For example, as Figure 1 and Figure 8B As shown, Figure 8B yes Figure 1 A schematic diagram of the coffee bean roasting apparatus shown in another state. Figure 1 The bottom surface 171 is in a removed state, and the bean inlet trough 17 is connected to the bean inlet channel 18; Figure 8B The bottom surface 171 in the middle is in a retracted state, and the bean input trough 17 is separated from the bean input channel.

[0112] A guide rail 19 is provided on one side of the bottom surface 171 of the bean feed hopper 17. The bottom surface 171 and a bean feed motor 20 are fixed to each other. The bean feed motor 20 is used to drive the bottom surface 171 to move along the guide rail 19 to connect or block the bean feed passage 18 and the bean feed hopper 17. Optionally, the bottom surface 171 is also fixed to a bean feed handle 21, allowing a user to move the bottom surface 171 along the guide rail 19 using the bean feed handle 21 to connect or block the bean feed passage 18 and the bean feed hopper 17. Optionally, a spring 191 is provided on the guide rail. When the user uses the bean feed handle 21 to move the bottom surface 171 away from the bean feed hopper 17 along the guide rail 19, the user needs to squeeze the spring 191 on the guide rail 19. When the user releases the bean feed handle 21, the bottom surface 171 is moved back into the bean feed hopper 17 under the action of the spring 191.

[0113] Alternatively, as Figure 2 As shown, the first bottom surface 112 of the baking chamber 11 faces the front panel ( Figure 2 (not shown), the bean inlet is provided in the upper half of the first bottom surface 112. The bean feed channel 18 is located between the front panel and the first bottom surface 112 of the roasting chamber. Optionally, the sides of the bean feed hopper 17 are sloped, and the bean feed hopper 17 as a whole has an inverted trapezoidal shape, which can reduce the bottom surface area while maintaining a large capacity and making the bottom surface easier to move.

[0114] Alternatively, as Figure 2As shown, an expansion slot 22 is provided above the bean feeder 17. The expansion slot has sloped sidewalls and a bottom that communicates with the bean feeder's opening. The expansion slot 22 facilitates the user's ability to increase the amount of beans fed. Optionally, a protective cover is secured above the bean feeder's opening, allowing coffee beans to enter the bean feeder through the gap between the opening and the protective cover. This protective cover prevents dust and foreign matter from entering the bean feeder.

[0115] In one example, the bottom surface of the bean feed trough may not be moved horizontally to connect or disconnect the bean feed trough and the bean feed channel. Figure 9 As shown, Figure 9 This is a cross-sectional schematic diagram of a portion of the structure of another embodiment of a coffee bean roasting device. The bean inlet 118 is provided on the side wall 114 of the roasting chamber, and the bean inlet trough 17 and the bean inlet channel 18 connecting the bean inlet trough 17 and the bean inlet 118 are located above the roasting chamber 11. The bottom surface 171 of the bean inlet trough 17 is specifically a plurality of loose-leaf pages. The outer side of the bean inlet trough 17 is provided with a rotating member 23 and a bean inlet motor ( Figure 9 The rotating member 23 can be manually rotated by a user or driven by the bean feeding motor 20 to expand or contract the movable leaf, thereby isolating or connecting the bean feeding channel 18 and the bean feeding trough 17.

[0116] Optionally, the bean inlet 118 is located at the top of the side wall 114, and a vertically extending baffle 24 is provided in the middle of the bean inlet channel 18 outside the bean inlet 118, for blocking the coffee beans thrown into the bean inlet channel 18 during stirring, so as to prevent the coffee beans discharged into the bean inlet channel 18 from being stuck between the paddle 1161 and the side wall 114.

[0117] There are many ways to structure beans out of the roasting chamber. Some examples are Figure 4 and Figure 10 As shown, Figure 10 yes Figure 4 The schematic diagram of the coffee bean roasting equipment shown is in the state where the door of the roasting bin is open. A fixed shaft 1141 parallel to the first rotating axis of the roasting bin is provided on the side wall 114 of the roasting bin 11, and the partial area of ​​the side wall 114 below the fixed shaft 1141 is the bin door 1142. The bin door 1142 can be rotated outward with the fixed shaft as the support axis under manual and / or motor drive to form the bean outlet 1143 of the roasting bin 11. The arrangement of the bin door in this example can minimize the space required for the movement of the bin door, which is conducive to the miniaturization of the coffee bean roasting equipment. In other examples, the bin door can also be arranged on the first bottom surface or the second bottom surface, and the movement of the bin door can be rotation around the fixed axis or translation, which is not limited here.

[0118] Optionally, the bean outlet 1143 formed after the door 1142 is opened is located directly below or to the side of the roasting chamber 11, so that the coffee beans can fall out of the roasting chamber 11 under the action of gravity after the door 1142 is opened, thus completing the bean discharge. Optionally, the opening direction of the roasting chamber door is consistent with the rotation direction of the paddle, so that the paddle can sweep all the coffee beans out of the bean outlet 1143. For example, Figure 10 In the example shown, the paddle 1161 rotates clockwise and moves to the left in the figure at the bean outlet 1143, so the chamber door 1142 is located on the left side of the roasting chamber and opens to the left.

[0119] There are many ways to open the door. In one example, a U-shaped groove 11421 is provided on the outer surface of the door 1142. A second rotating shaft 25 and a moving member 26 fixed to the second rotating shaft 25 and located in the U-shaped groove 11421 are also provided outside the baking chamber 11. The second rotating shaft 25 is used to drive the moving member 26 to rotate around the second rotating shaft 25, so as to abut against the inner wall of the U-shaped groove 11421 and drive the U-shaped groove 11421, and then drive the door 1142 to rotate outward or inward, so that the door is opened or closed. Optionally, as Figure 1 and Figure 10 As shown, the movable member 25 is strip-shaped and parallel to the second rotating shaft 25. The movable member 25 can be fixed to the rotating shaft 25 via a connecting member 27. The second rotating shaft 25 is fixed to a bean dispensing motor (not shown) and / or a bean dispensing handle 28, and rotates when driven by the bean dispensing motor and / or the bean dispensing handle 28.

[0120] A bean-discharging handle is provided so that emergency human intervention can be made in the event that the software system of the coffee bean roasting equipment is stuck. In addition, the speed of opening the bin door when discharging beans manually can be faster, which is convenient for users to use in scenarios where beans need to be discharged quickly. A bean-discharging motor is provided so that the opening and closing of the bin door can be automatically controlled to achieve automatic bean discharge. For example, the processing component is also used to obtain the expansion rate, color value or temperature of the coffee beans based on the visible light image. The device also includes a control component for controlling the bean-discharging motor to drive the bin door to open to achieve automatic bean discharge when the expansion rate of the coffee beans reaches a target expansion rate, or when the color value of the coffee beans reaches a target color value, or when the temperature of the coffee beans reaches a target temperature. The target expansion rate, target color value or target temperature can be a default value, or a value set by the user.

[0121] Some examples, such as Figure 10As shown, a bean discharge bin 29 is provided outside the roasting bin below the bin door. When the bin door 1142 is opened, the coffee beans in the roasting bin are moved into the bean discharge bin 29. For example, the coffee beans can fall into the bean discharge bin under the action of gravity, or the coffee beans can be swept into the bean discharge bin by a stirring rod. Optionally, the side wall of the bean discharge bin is located on the side or front of the coffee bean roasting device, making it convenient for the user to pull the bean discharge bin out of the coffee bean roasting device.

[0122] In some examples, a vibration module (not shown) is further provided on the outer side of the bottom of the bean discharging bin for vibrating the bottom of the bean discharging bin to improve the uniformity of the distribution of the coffee beans in the bean discharging bin and prevent the coffee beans in the bean discharging bin from piling up into a mountain and blocking the bean outlet of the roasting bin.

[0123] Some examples, such as Figure 1 and Figure 10 As shown, a closed cavity 30 is provided on the outside of the bottom of the bean discharge bin 29. A through hole 291 is provided at the bottom of the bean discharge bin 29, connecting the bean discharge bin 29 to the closed cavity 30. A cooling fan (not shown) is also provided on the outside of the closed cavity 30 to cool the closed cavity and the bean discharge bin. Optionally, a heat insulation layer is provided on at least part of the outer surface of the closed cavity 30 and the bean discharge bin 29 to prevent heat from the roasting chamber 11 from being transferred into the closed cavity 30 and the bean discharge bin 29, which would slow the heat dissipation of the coffee beans in the bean discharge bin.

[0124] Optionally, the coffee bean roasting device is further provided with a temperature sensor for detecting the temperature of the coffee beans in the bean hopper. The temperature sensor may be located within the bean hopper, within a sealed chamber below the bean hopper, or near the bean hopper, without limitation. The device further includes a control component for controlling the cooling fan to stop cooling the sealed chamber and the bean hopper when the temperature measured by the temperature sensor is lower than a preset temperature, when the temperature change measured by the temperature sensor is lower than a preset temperature change, or when the difference between the temperature measured by the temperature sensor and room temperature is less than a preset difference. In some examples, when the cooling fan in the bean hopper stops cooling the bean hopper, the bean hopper automatically ejects from the coffee bean roasting device. Optionally, the control component is further configured to automatically start cooling the coffee beans in the bean hopper when it detects that the temperature in the bean hopper is higher than a preset value. This allows the bean hopper to automatically begin cooling the beans as they are discharged.

[0125] Some examples, such as Figure 2 and Figure 5As shown, a sampling hole 119 is provided on the first bottom surface 112 of the roasting chamber to facilitate the user's extraction of coffee bean samples from the roasting chamber 11 during the roasting process. Optionally, the sampling hole 119 is covered by a barrier 120 secured to the first bottom surface 112 by a torsion spring. This allows a sampling rod 31 to pass through the sampling hole 119 and push past the barrier 120 to extract a coffee bean sample from the roasting chamber. After the sampling rod 31 exits the roasting chamber 11, the barrier 120, acting under the action of the torsion spring, covers the sampling hole. The barrier prevents air exchange between the roasting chamber and the outside environment, which could affect the temperature and pressure in the roasting chamber. Optionally, the main structural member 14 also includes a channel 142 extending through the front panel 141 and the sampling hole 119. The sampling rod 31 is inserted into this channel 142 to extend into the roasting chamber 11. The setting of the channel 142 can facilitate the sampling operation of the user.

[0126] In some examples, the baking chamber is further provided with a smoke outlet, which can be provided on the first bottom surface, the second bottom surface or the side wall. Figure 1 In the figure, the smoke outlet is provided on the first bottom surface 112 and shares the same outlet with the bean inlet 118 as an example, so that the structure can be more compact.

[0127] like Figure 11 and Figure 12 They are schematic diagrams of two different cross sections of an embodiment of the coffee bean roasting device of the present application. Figure 11 and Figure 12 As shown, in some examples, the coffee bean roasting apparatus is further provided with an exhaust fan 33 and a rind separation chamber 34. The rind separation chamber 34 has a smoke inlet 341, a smoke outlet 342, and a rind outlet 343. The apparatus is also provided with a smoke exhaust duct 35 connecting the smoke outlet and the smoke inlet 341. Fumes from the exhaust duct 35, mixed with hot air and rind, are drawn into the rind separation chamber 34 through the smoke inlet 341 by the exhaust fan 33. The hot air is then drawn upward by the exhaust fan and discharged through the smoke outlet 342, causing the rind to rotate and fall due to the incoming air pressure. A closed rind bin 36 is provided below the rind outlet 343 to receive fallen rinds, which can be removed from the coffee bean roasting apparatus by pulling.

[0128] For example, Figure 10 and Figure 11As shown, in the example where the roasting assembly includes a halogen lamp 124 and the halogen lamp is disposed on the top of the roasting chamber 11, the smoke exhaust duct 35 can be located above the halogen lamp 124 and communicate with the bean inlet duct 18. Since the bottom surface of the bean inlet hopper is essentially in a state of separating the bean inlet hopper and the bean inlet duct during the roasting process, smoke generated within the roasting chamber during the roasting process can be drawn into the rind separation chamber 34 through the smoke outlet and the smoke exhaust duct by the exhaust fan 33, thereby separating the rind from the hot air within the rind separation chamber 34. The separated rind then falls from the rind outlet 343 of the rind separation chamber into the rind bin 36, and the separated hot air is discharged from the coffee bean roasting apparatus through the smoke exhaust duct 342 of the rind separation chamber 34.

[0129] In some examples, the silver skin separation chamber and the hot air pipe are both vertically extended and arranged side by side on one side of the coffee bean roasting equipment. Figure 11 As shown, the hot air duct 121 and the roasting chamber 11 are arranged side by side behind the front panel 141. The hot air duct 121 is located outside the side wall of the roasting chamber 11, the shavings separation chamber 34 is located behind the hot air duct 121, and the shavings bin 36 is located below the shavings separation chamber 34 and at the bottom side of the entire coffee bean roasting device. Optionally, the shavings bin 36 occupies a majority of the entire side of the coffee bean roasting device, thereby ensuring a compact layout of the various modules within the coffee bean roasting device while increasing the volume of the shavings bin. The shavings bin is located at the bottom side of the coffee bean roasting device, making it easy for the user to pull out the shavings bin for cleaning. Optionally, the bean discharge hopper is located below the roasting chamber door and at the bottom of the other side of the coffee bean roasting device, allowing the user to pull out the bean discharge hopper from the other side of the coffee bean roasting device to retrieve beans. Optionally, the bean inlet and outlet handles are located on the same side of the coffee bean roasting device, ensuring both aesthetics and user convenience.

[0130] Silver warehouse inspection and cleaning

[0131] In some examples, a first sensor is provided in the silver leather bin, and when the first sensor detects that the user has pulled out the silver leather bin, the exhaust fan is stopped. Optionally, the first sensor may be a magnetic proximity switch or a magnetically controlled switch.

[0132] When the amount of silver skin accumulated in the silver skin bin is large, a safety hazard may occur, or the silver skin may accumulate at the silver skin outlet of the silver skin separation bin, causing the silver skin to occupy the silver skin separation bin. Optionally, the embodiment of the present application also detects the amount of silver skin accumulated in the silver skin bin, and / or the height of the silver skin accumulation below the silver skin outlet of the silver skin separation bin. Optionally, when it is detected that the amount of silver skin accumulated in the silver skin bin exceeds a preset amount, and / or the height of the silver skin accumulation below the silver skin outlet exceeds a preset height, the display screen is also used to remind the user to clean it. Alternatively, the silver skin bin is in the shape of a long strip, and a movable plate is also provided in the silver skin bin. When it is detected that the height of the silver skin accumulation below the silver skin outlet exceeds a preset height, the movable plate is used to push the silver skin below the silver skin outlet away from the bottom of the silver skin outlet.

[0133] Among them, there are multiple ways of detection. In some examples, a second sensor is provided in the shavings bin to detect the height or amount of shavings accumulation below the shavings outlet. Optionally, the second sensor can be a laser ranging sensor. The laser ranging sensor can be installed on the top or side wall of the shavings bin, wherein when installed on the top, the amount of shavings accumulation can be measured more comprehensively. In some examples, the processing component is used to obtain the amount of coffee beans based on the imaging of the visible light imaging module, and predict the amount of shavings in the shavings bin based on a preset model and the amount of coffee beans. The preset model can be established by experimenting with different amounts of coffee beans and the corresponding shavings, or trained through big data, and then pre-stored in the coffee bean roasting equipment.

[0134] Since the hot air in the silver skin separation bin may cause the temperature of the exhaust fan to rise, optionally, the coffee bean roasting equipment is also provided with a heat sink or a cooling fan on one side of the exhaust fan, or an insulation layer is also provided between the silver skin separation bin and the exhaust fan to reduce the heat conducted from the silver skin separation bin to the exhaust fan.

[0135] In some examples, the coffee bean roasting apparatus further includes a smoke purification assembly connected to the smoke exhaust port. The smoke purification assembly includes a fan, a second heating module, a smoke purification material, and an air outlet. Optionally, the smoke purification assembly is built into the main structural member of the coffee bean roasting apparatus. Alternatively, the smoke purification assembly is disposed externally to the main structural member of the coffee bean roasting apparatus and can be removably connected to the smoke exhaust port of the coffee bean roasting apparatus as an accessory of the coffee bean roasting apparatus. For example, the smoke purification assembly further includes an air inlet for removably connecting to the smoke exhaust port.

[0136] like Figure 13 As shown, Figure 13 This is a schematic diagram of the main structure of an embodiment of the smoke purification component. In the example where the smoke purification component can be used as an accessory and detachably connected to the smoke exhaust port of the coffee bean roasting equipment, Figure 13The main structure shown is added with the outer shell to form a separate accessory or a separate coffee bean roasting and smoke purification device. Figure 14 As shown, Figure 14 The middle left picture is an external diagram of the coffee bean roasting and smoke purification equipment, and the right picture is a cross-sectional diagram of the coffee bean roasting and smoke purification equipment.

[0137] like Figure 13 and Figure 14 As shown, in some examples, the fan 37, second heating module 38, smoke purifying material 39, and air outlet 40 are arranged in sequence, with an air inlet 41 located on one side of the fan 37. The air inlet 41 can be directly connected to the smoke outlet, or can be connected via a hose. The fan 38 is used to transport gas from the smoke outlet to pass through the second heating module 38 and the smoke purifying material 39 in sequence. After the gas is heated by the second heating module 38, at least some of the harmful components are removed by the smoke purifying material 39 before being discharged from the air outlet 40.

[0138] Optionally, the second heating module 38 includes a heating element and a heat-insulating material included outside the heating element to reduce the loss of temperature generated by the heating element.

[0139] Among them, the smoke purification material 39 includes a catalyst and a carrier, wherein the catalyst includes platinum, and the carrier includes iron, chromium, and aluminum. The smoke purification material 39 adopts catalytic combustion (oxidation) technology, and the oil smoke is heated to a certain temperature by the second heating module to prepare for the catalytic reaction, and then enters the smoke purification material and contacts the catalyst. The catalyst can reduce the activation energy of the chemical reaction, thereby promoting the decomposition of organic matter in the oil smoke into carbon dioxide and water vapor at a lower temperature. The harmful components of the gas after the catalytic reaction are greatly reduced. According to testing, after the oil smoke passes through the smoke purification material, at least one of its methanol, styrene, ethylbenzene, para-xylene, acetaldehyde, and toluene can be greatly reduced. The smoke purification material in this example can remove harmful substances at a lower temperature (for example, about 200 degrees). Compared with other smoke purification methods in the prior art (such as post-combustion methods) that require high temperatures, this example can reduce the power consumption of the smoke purification component.

[0140] In some examples, a first wind pressure sensor is further provided within the smoke purification assembly, and a second wind pressure sensor is provided at the smoke exhaust port. The first wind pressure sensor may include at least one probe distributed within the smoke purification assembly. The smoke purification assembly also includes a control module configured to obtain measurement data from the first wind pressure sensor and data from the second wind pressure sensor. Optionally, the control module may obtain measurement data from the second wind pressure sensor via a wireless communication module (e.g., Bluetooth).

[0141] The control module is further configured to control the fan based on the measurement data from the first wind pressure sensor and the data from the second wind pressure sensor, so that the air intake of the air inlet matches the air output of the smoke exhaust port. This prevents the motor from exhausting more air than the smoke exhaust port, thereby removing hot air from the baking chamber.

[0142] Alternatively, in some examples, the smoke purification component includes a control member 42 for receiving the air intake amount input by the user. The control module is used to control the fan 38 according to the air intake amount input by the user. For example, Figure 13 and Figure 14 As shown, the smoke purifier housing is further provided with a knob 42 for adjusting the air intake volume. Optionally, the smoke purifier has a preset range of available air intake values, and the user can adjust the percentage by rotating the knob 42. The control module is configured to calculate a corresponding air intake value based on the percentage and the available range, and control the fan 38 based on the air intake value.

[0143] Optionally, the second heating module can have multiple heating methods. In some examples, the control module is used to obtain a control temperature input by a user, and to control the heating temperature of the second heating module according to the control temperature. In some examples, the control module is used to automatically adjust the heating temperature of the second heating module according to the measurement data of the first wind pressure sensor, so that the temperature of the gas heated by the second heating module reaches a preset temperature. Since the smoke purification material has the highest efficiency within certain temperature ranges, the smoke purification effect is the best. The control module can adjust the heating temperature of the second heating module in real time according to the air intake volume, so that the temperature of the heated gas is maintained within the optimal temperature range.

[0144] Optionally, a display interface 43 is also provided on the shell of the smoke purification component for displaying various parameters of the smoke purification component, such as the air intake volume selected by the user, or the heating temperature of the second heating module selected by the user, or the actual heating temperature of the second heating module.

[0145] The visible light imaging module may output only one type of visible light image, or may output different types of visible light images, so that the processing component can obtain more information about the coffee beans.

[0146] In some examples, the fill light assembly includes a first light assembly configured to emit visible light, and the visible light imaging module is configured to capture the first type of image of the coffee beans when the first light assembly emits white light. For example, the visible light may be white light, and the visible light imaging module generates an RGB image sequence of the coffee beans.

[0147] In some examples, the fill light assembly includes a second light assembly that emits near-infrared light, and the visible light imaging module is configured to capture the second type of image of the coffee beans when the second light assembly emits light. For example, the second light assembly is configured to emit an 850 nm light beam.

[0148] In some examples, the fill light group includes a first light group and a second light group. The first light group and the second light group are configured to alternately emit light when the visible light imaging module images the coffee beans. The visible light imaging module is configured to acquire an RGB image sequence of the coffee beans when the first light group emits visible light, and to acquire a near-infrared image sequence of the coffee beans when the second light group emits light.

[0149] After the processing component obtains the second type of image reflected by the coffee beans and received by the visible light imaging module, it can calculate the chromaticity value of the coffee beans based on the second type of image. In one example, the visible light imaging module includes a two-dimensional detector with multiple pixels, which is used to detect the received near-infrared light and generate a corresponding electrical signal. The processing component pre-stores the correspondence between the electrical signal intensity and the chromaticity value, and calculates the corresponding chromaticity value based on the electrical signal intensity value of each pixel in the near-infrared image obtained by the two-dimensional detector to obtain a chromaticity diagram. Alternatively, the processing component can also obtain a chromaticity distribution histogram based on the chromaticity value of the pixel position corresponding to each coffee bean, and use the average value of the chromaticity distribution histogram as the overall chromaticity value.

[0150] In some examples, the coffee bean roasting equipment further includes a sound sensor for detecting sound information from the coffee beans within the roasting chamber. The processing component is further configured to obtain the time corresponding to the cracking sound based on the sound information, and to determine the first crack time of the coffee beans based on the time corresponding to the cracking sound. The sound sensor can be installed in various locations within the coffee bean roasting equipment. For example, it can be installed on the outer surface of the roasting chamber. In one example, the sound sensor is located within the housing of the imaging assembly. The coffee bean roasting equipment further includes a main structural member, to which the imaging module is removably secured to the roasting chamber. The processing assembly includes a first processor within the imaging module and a second processor within the main structural member. The first processor is configured to time-align the fused image with the sound information acquired by the sound sensor and transmit the result to the second processor. The second processor is further configured to acquire detection data from at least one sensor within the main structural member. This allows the imaging assembly to be more modular, directly transmitting the aligned video and audio data to the processor within the coffee bean roasting equipment.

Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
