Description

Technical Field

[0001] This invention relates to the field of coffee bean roasting technology, and in particular to a coffee bean roasting machine. Background Technology

[0002] Currently, most existing coffee bean roasters use hot air to blow coffee beans in a container, causing them to heat up and bounce against the side wall of the container to roast the beans and remove the silverskin. However, because the direction of heating is fixed, the entire surface of the coffee bean cannot be heated evenly, resulting in poor roasting effect and ineffective removal of the silverskin, which affects the quality of the coffee beans. Summary of the Invention

[0003] The purpose of this invention is to provide a coffee bean roaster that not only ensures even heating of coffee beans and improves roasting results, but also effectively removes the silverskin from the surface of coffee beans.

[0004] To achieve the above objectives, the present invention provides a coffee bean roaster, comprising: a base, a roasting dish, a conveying pipe, a storage compartment, and an air supply device; the base has a ventilation hole on one side; the air supply device is disposed inside the base and is used to provide hot air to the ventilation hole; the roasting dish is mounted on the base, the roasting dish includes a dish body and a filter screen, the two ends of the dish body are open, and one end is correspondingly disposed and connected to the ventilation hole; the filter screen is disposed at the end of the dish body adjacent to the ventilation hole, the filter screen includes a first filter section and a second filter section, the first filter section and the second filter section are arranged sequentially along a first direction, the first filter section and the second filter section have the same area, and the mesh size of the first filter section is greater than that of the second filter section; the conveying pipe has an inlet and an outlet, the inlet is connected to the end of the dish body opposite to the ventilation hole, and the outlet is connected to the storage compartment.

[0005] Optionally, the base has a first groove on one side with the ventilation hole. The first groove extends along the first direction and passes through the base on one side in the first direction. The end of the dish body adjacent to the ventilation hole is slidably connected to the first groove. The ventilation hole is opened on the bottom surface of the first groove. The end of the dish body adjacent to the ventilation hole can slide along the first groove to correspond to the ventilation hole.

[0006] Optionally, it also includes a first temperature measuring device, which is installed on the side of the base with the ventilation hole. The first temperature measuring device has a probe end extending along the first direction. The probe end and the first slide groove are correspondingly arranged. A probe hole is opened on the side of the dish. As the dish slides along the first slide groove, the probe end can pass through the probe hole and extend into the interior of the dish.

[0007] Optionally, the conveying pipe includes a first extension, a second extension, and a third extension. The first extension extends along a second direction and is mounted at one end on the base and spaced apart from the ventilation holes. One end of the second extension is connected to the other end of the first extension, and the other end of the second extension extends obliquely toward the end of the dish body away from the ventilation holes. The third extension extends along the first direction and is connected at one end to the other end of the second extension. The inlet is located on the side of the third extension facing the dish body, and the outlet is located on the side of the first extension. The placement chamber can slide along the outlet into the interior of the first extension, so that the opening of the placement chamber is connected to the interior of the conveying pipe.

[0008] Optionally, the third extension is further provided with a protrusion on the side facing the dish body. The protrusion has a second groove extending along the first direction, and the second groove passes through the side of the protrusion away from the placement compartment. The input port is provided on the top surface of the second groove, and the end of the dish body away from the ventilation hole can slide along the second groove to connect with the input port.

[0009] Optionally, the placement compartment includes a compartment body and a first handle, the compartment body being slidable along the output port, and the first handle being located on the side of the compartment body opposite to the output port.

[0010] Optionally, a second temperature measuring device is also included. The base has a receiving groove on the side facing the baking dish. The ventilation hole is located on the bottom surface of the receiving groove. The second temperature measuring device is located in the receiving groove and is used to detect the temperature of the gas in the receiving groove.

[0011] Optionally, the dish body is transparent.

[0012] Optionally, the baking dish may also include a second handle, which is mounted on the side of the dish body.

[0013] Optionally, the baking dish includes multiple layers of the filter screen, and the multiple layers of the filter screen are stacked sequentially along the second direction.

[0014] Compared with the prior art, the coffee bean roaster of this invention has the following advantages: the device divides the filter on the roasting dish into a first filter section and a second filter section, and sets the mesh size of the first filter section to be greater than that of the second filter section. This ensures that the pressure generated by the hot air supplied by the air supply device through the ventilation holes and reaching the filter is less than that generated by the hot air through the second filter section. This causes the coffee beans to circulate and tumble in the roasting dish in the same direction, so that the entire surface of the coffee beans can be heated evenly, thereby improving the roasting effect. Furthermore, during the tumbling process of the coffee beans, the silver skin that falls off due to the impact of the roasting dish is transported to the placement chamber by the hot air through the conveying pipe, thereby achieving the function of removing the silver skin from the surface of the coffee beans.

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0027] like Figures 1-5As shown, an embodiment of the present invention provides a coffee bean roaster, comprising: a base 1, a roasting dish 2, a conveying pipe 3, a storage chamber 4, and an air supply device; the base 1 has a ventilation hole 11 on one side; the air supply device is disposed inside the base 1 and is used to supply hot air to the ventilation hole 11; the roasting dish 2 is mounted on the base 1, and the roasting dish 2 includes a dish body 21 and a filter screen 22, the two ends of the dish body 21 are open, and one end is correspondingly disposed and connected to the ventilation hole 11, and the filter screen 22 is disposed at the end of the dish body 21 adjacent to the ventilation hole 11. The filter screen 22 includes a first filter section 221 and a second filter section 222. The first filter section 221 and the second filter section 222 are arranged sequentially along the first direction X. The areas of the first filter section 221 and the second filter section 222 are the same, and the mesh count of the first filter section 221 is greater than that of the second filter section 222. The conveying pipe 3 has an inlet 332 and an outlet 311. The inlet 332 is connected to the end of the dish body 21 away from the ventilation hole 11, and the outlet 311 is connected to the placement chamber 4.

[0028] Based on the above scheme, the device divides the filter 22 on the roasting dish 2 into a first filter section 221 and a second filter section 222, and sets the mesh size of the first filter section 221 to be greater than that of the second filter section 222. This ensures that the pressure generated by the hot air supplied by the air supply device through the ventilation hole 11 and reaching the filter 22 is less than that generated by the hot air through the second filter section 222. This causes the coffee beans to circulate and tumble in the roasting dish in the same direction, so that the entire surface of the coffee beans can be heated evenly to improve the roasting effect. During the tumbling process of the coffee beans, the silver skin that falls off due to the impact of the roasting dish 2 is transported by the hot air through the conveying pipe 3 to the placement chamber 4, thereby achieving the function of removing the silver skin from the surface of the coffee beans.

[0029] like Figure 2 As shown, in order to facilitate the positioning of the baking dish 2 and prevent the baking dish 2 from being misaligned during the baking process, a first groove 12 is also provided on the side of the base 1 with the ventilation hole 11. The first groove 12 extends along the first direction X and passes through the base 1 on one side of the first direction X. The end of the dish body 21 adjacent to the ventilation hole 11 is slidably connected to the first groove 12. The ventilation hole 11 is opened on the bottom surface of the first groove 12. The end of the dish body 21 adjacent to the ventilation hole 11 can slide along the first groove 12 to correspond to the ventilation hole 11.

[0030] like Figure 2As shown, in order to detect the temperature of coffee beans in roasting dish 2 in real time, a first temperature measuring device 6 is also included. The first temperature measuring device 6 is installed on the side of the base 1 with ventilation holes 11. The first temperature measuring device 6 has a detection end 61 extending along the first direction X. The detection end 61 and the first slide groove 12 are correspondingly arranged. A detection hole 211 is opened on the side of the dish body 21. As the dish body 21 slides along the first slide groove 12, the detection end 61 can pass through the detection hole 211 and extend into the interior of the dish body 21.

[0031] like Figure 6 As shown, to prevent silver from accumulating in the conveying pipe 3, the conveying pipe 3 includes a first extension 31, a second extension 32, and a third extension 33. The first extension 31 extends along the second direction Y, and one end is mounted on the base 1 and spaced apart from the ventilation holes 11. One end of the second extension 32 is connected to the other end of the first extension 31, and the other end of the second extension 32 extends obliquely toward the end of the dish 21 away from the ventilation holes 11. The third extension 33 extends along the first direction X, and one end is connected to the other end of the second extension 32. The inlet 332 is located on the side of the third extension 33 facing the dish 21, and the outlet 311 is located on the side of the first extension 31. The placement chamber 4 can slide along the outlet 311 into the interior of the first extension 31, so that the opening of the placement chamber 4 is connected to the interior of the conveying pipe 3.

[0032] like Figure 6 As shown, in order to facilitate the positioning of the baking dish 2 and avoid misalignment of the baking dish 2 during the baking process, the third extension 33 is provided with a protrusion 331 on the side facing the dish body 21. The protrusion 331 has a second groove 3311 extending along the first direction X, and the second groove 3311 passes through the side of the protrusion 331 away from the placement compartment 4. The input port 332 is located on the top surface of the second groove 3311. The end of the dish body 21 away from the ventilation hole 11 can slide along the second groove 3311 to connect with the input port 332.

[0033] like Figure 7 As shown, in order to facilitate the retrieval of the placement compartment 4, the placement compartment 4 includes a compartment body 41 and a first handle 42. The compartment body 41 can slide along the output port 311, and the first handle 42 is located on the side of the compartment body 41 away from the output port 311.

[0034] like Figure 2 As shown, in order to monitor the temperature of the hot air provided by the air supply device in real time, a second temperature measuring device 7 is also included. The base 1 also has a receiving groove 13 on the side facing the baking dish. The ventilation hole 11 is provided on the bottom surface of the receiving groove 13. The second temperature measuring device 7 is provided in the receiving groove 13 for detecting the temperature of the gas in the receiving groove 13.

[0035] Optionally, the dish 21 can be made transparent so that the coffee beans can be observed in real time.

[0036] like Figure 4 As shown, in order to facilitate the handling of the baking dish 2, the baking dish 2 also includes a second handle 23, which is installed on the side of the dish body 21.

[0037] like Figure 4 As shown, in some embodiments, the dish body 21 is cylindrical, and the baking dish 2 also includes a base 24 and a top seat 25. The base 24 and the top seat 25 are respectively disposed at both ends of the dish body 21, and the base 24 has a first connecting hole, and the top seat 25 has a second connecting hole. The ventilation hole 11, the first connecting hole, the interior of the dish body 21 and the second connecting hole are connected in sequence. The filter screen 22 is disposed in the first connecting hole, and the base 24 can slide along the first sliding groove 12, and the top seat 25 can slide along the second sliding groove 3311. The two ends of the handle are respectively connected to the top seat 25 and the base 24.

[0038] Optionally, in order to ensure that the coffee beans can be tumbled stably, the roasting dish includes multiple layers of filters 22, and the multiple layers of filters 22 are stacked sequentially along the second direction Y.

[0039] like Figure 8 As shown, in some embodiments, the air supply device 5 includes a cylinder 51, a fan 52, and a heating element 53. The cylinder 51 is located inside the base 1, with one end corresponding to the ventilation hole 11. The heating element 53 and the fan 52 are located in the cylinder 51, with the heating element 53 located between the fan 52 and the ventilation hole 11. The base 1 also includes a ventilation port 14, which is located on the side of the base 1. As the fan 52 rotates and the heating element 53 heats up, the airflow from outside the base 1 enters the interior of the base 1 through the ventilation port 14, and enters the cylinder 51 under the drive of the fan 52. It then passes through the heating element 53 and the ventilation hole 11 and enters the filter screen 22.

[0040] In summary, the present invention provides a coffee bean roaster, which divides the filter 22 on the roasting dish 2 into a first filter section 221 and a second filter section 222, and sets the mesh size of the first filter section 221 to be greater than that of the second filter section 222. This ensures that the pressure generated by the hot air supplied by the air supply device through the ventilation hole 11 to the filter 22 is less than that generated by the hot air through the second filter section 222. This causes the coffee beans to circulate and tumble in the roasting dish in the same direction, thereby ensuring that the entire surface of the coffee beans is heated evenly to improve the roasting effect. Furthermore, during the tumbling process of the coffee beans, the silver skin that falls off due to the impact of the roasting dish 2 is transported by the hot air through the conveying pipe 3 to the placement chamber 4, thereby achieving the function of removing the silver skin from the surface of the coffee beans.

[0041] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
