Description

Technical Field

[0001] The present application relates to the field of coffee roasting, and in particular to a coffee roasting machine. Background Art

[0002] Before grinding and making coffee, the coffee needs to be roasted to stimulate the flavor substances in the coffee, thus ensuring that the taste of the coffee meets the needs of the drinker.

[0003] In the existing related technology, coffee roasting is generally completed by a roasting machine. For details, please refer to the utility model patent with announcement number CN220088515 U, which discloses a coffee bean roasting machine. Figure 2 , its air inlet, fan and heating element are all located at the bottom of the baking chamber, and its air outlet is located at the top of the baking chamber.

[0004] During roasting, air enters the roaster through the bottom air inlet and is driven upward by the fan. The air is heated by the heating element to produce roasting hot air, which then flows upward through the roasting chamber, roasting the coffee beans. After contacting the coffee beans, the roasting hot air is discharged into the air through the top air outlet, completing the roasting process.

[0005] With respect to the above-mentioned related technologies, the contact time between the roasting hot air and the coffee beans is short, resulting in low roasting efficiency of the coffee beans. Summary of the Invention

[0006] In order to improve the roasting efficiency of coffee beans, the present application provides a coffee roasting machine.

[0007] The coffee roasting machine provided in this application adopts the following technical solution:

[0008] A coffee roaster comprises a roaster body and a roasting container, wherein the roasting container is detachably mounted on the roaster body and has a storage compartment for storing coffee beans to be roasted.

[0009] The baking machine body is provided with an air inlet and an air outlet, the air inlet is used to blow baking hot air into the accommodating bin, and the air outlet is used to discharge the baking hot air in the accommodating bin, and the air inlet and the air outlet are located on the same side of the accommodating bin.

[0010] By adopting the above technical solution, roasting hot air enters the storage bin through the air inlet and then leaves the storage bin through the air outlet, thereby roasting the coffee beans in the storage bin. Because the air inlet and air outlet are located on the same side of the storage bin, the roasting hot air first blows from the air inlet toward the coffee beans in a first direction. After being forced to pass through the gaps between the coffee beans and contacting the inner wall of the storage bin, it leaves the storage bin through the air outlet in a second direction opposite to the first direction. This ensures that the roasting hot air and the coffee beans are fully contacted, making it easier to roast the coffee beans in a shorter time.

[0011] Optionally, the air inlet and the air outlet are both located at the top of the accommodating compartment.

[0012] By adopting the above technical solution, the first direction is set downward and the second direction is set upward, which makes it easier to roast the coffee beans placed in the accommodating bin under the action of gravity more evenly.

[0013] Optionally, the baking machine body is provided with an air intake channel, the input end of the air intake channel is connected to the atmosphere, the output end of the air intake channel is connected to the air inlet, an air intake fan is installed inside the air intake channel, and a heating element is installed at the output end of the air intake channel, and the heating element, air inlet and air outlet are located on the same side of the accommodating bin.

[0014] By adopting the above technical solution, the air intake fan allows atmospheric air to enter the air intake channel, and forms roasting hot air after passing through the heating element, so that the roasting hot air enters the storage bin and roasts the coffee beans in the storage bin.

[0015] Optionally, the roasting machine body is provided with a smoke removal chamber, the input end of the smoke removal chamber is connected to the accommodating bin, the output end of the smoke removal chamber is connected to the air outlet, and a smoke filter is installed inside the smoke removal chamber, and the smoke filter is used to absorb smoke generated by the coffee beans during roasting.

[0016] By adopting the above technical solution, the smoke filter can filter the smoke generated during the roasting of coffee beans, which is helpful to reduce the odor generated in the atmosphere.

[0017] Optionally, a smoke removal heating wire is installed in the smoke removal chamber, and the smoke removal heating wire is located between the smoke filter and the input end of the smoke removal chamber.

[0018] By adopting the above technical solution, the smoke removal heating wire heats and burns the smoke generated by the coffee beans during roasting, reducing the content of combustible particles in the smoke, thereby slowing down the speed at which smoke particles accumulate in the smoke filter, which is beneficial to extending the service life of the smoke filter.

[0019] Optionally, the baking container is rotatably mounted with a stirring plate, the stirring plate is located in the accommodating bin, and the baking machine body is mounted with a stirring driving member, the stirring driving member is used to drive the stirring plate to rotate.

[0020] By adopting the above technical solution, the stirring plate stirs the coffee beans in the storage chamber, which helps to increase the contact between the coffee beans and the roasting hot air, thereby improving roasting efficiency. It also facilitates the discharge of smoke generated by the coffee beans at the bottom, thereby reducing the impact of the smoke on the coffee bean flavor.

[0021] Optionally, a shell discharge hole is provided at the bottom of the baking container, the shell discharge hole is arranged through, and the shell discharge hole is arranged in a spiral shape.

[0022] By adopting the above technical solution, the shells of the coffee beans will be peeled off after contacting the inner wall of the shell discharge hole, which is beneficial to improving the subsequent grinding quality of the coffee beans and reducing the situation where the coffee bean shells block the roasting hot air, making it easier to complete the roasting of the coffee beans in a shorter time.

[0023] Optionally, a sealing gasket is installed on the edge of the accommodating bin.

[0024] The above technical solution helps ensure the sealing of the storage chamber when the roasting container is installed in the roaster body, thereby increasing the air pressure in the storage chamber during the roasting process, ensuring sufficient contact between the roasting hot air and the coffee beans, and preventing the smoke generated during roasting from being directly dissipated into the atmosphere.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. Roasting hot air enters the storage bin through the air inlet and then leaves the storage bin through the air outlet, thereby roasting the coffee beans in the storage bin. Because the air inlet and air outlet are located on the same side of the storage bin, the roasting hot air first blows from the air inlet toward the coffee beans in a first direction. Then, after being forced to pass through the gaps between the coffee beans and contacting the inner wall of the storage bin, it leaves the storage bin through the air outlet in a second direction opposite to the first direction. This ensures that the roasting hot air fully contacts the coffee beans, making it easier to roast the coffee beans in a shorter time.

[0027] 2. The smoke removal heating wire heats and burns the smoke produced by roasting coffee beans, reducing the content of combustible particles in the smoke, thereby slowing the accumulation of smoke particles in the smoke filter, thereby helping to extend the service life of the smoke filter;

[0028] 3. The stirring plate is located in the accommodating chamber, and the baking machine body is equipped with a stirring drive member, which is used to drive the stirring plate to rotate;

[0029] 4. The shells of the coffee beans will be peeled off after they come into contact with the inner wall of the shell discharge hole, which is beneficial to improving the subsequent grinding quality of the coffee beans and reducing the situation where the coffee bean shells block the roasting hot air, making it easier to complete the roasting in a shorter time.

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-4 This application is described in further detail.

[0036] The present application embodiment discloses a coffee roasting machine. Figure 1 The coffee roaster includes a roaster body 1 and a roasting container 2. A container slot is provided on the side of the roaster body 1. The roasting container 2 is inserted into the container slot from the side of the roaster body 1 and installed in the roaster body 1. Alternatively, the roasting container 2 can be removed from the roaster body 1 by pulling out of the container slot from the side of the roaster body 1.

[0037] Reference Figure 2 The roasting container 2 includes a cylindrical storage compartment 201 for storing coffee beans to be roasted. A circular sealing gasket 21 is mounted on the top edge of the roasting container 2. When the roasting container 2 is inserted into the container slot, the sealing gasket 21 abuts against the inner wall of the slot, preventing the gas in the storage compartment 201 from escaping into the atmosphere and reducing odors during the roasting process.

[0038] The roasting container 2 is rotatably mounted with a stirring plate 22 located within the coffee container 201 to agitate the coffee beans within the container 201 during roasting. A stirring drive 11 is fixedly mounted to the bottom of the roaster body 1. In this embodiment, the stirring drive 11 is a motor. When the roasting container 2 is mounted on the roaster body 1, the output shaft of the stirring drive 11 is mounted to the stirring plate 22, thereby driving the stirring plate 22 to rotate.

[0039] Reference Figure 2 and Figure 3 A plurality of shell discharge holes 202 are formed through the bottom of the roasting container 2. The plurality of shell discharge holes 202 are axially distributed around the axis of the accommodating chamber 201 and are arranged in a spiral shape. When the stirring plate 22 stirs the coffee beans, the coffee bean shells are removed by contact and collision between the coffee bean shells and the inner walls of the shell discharge holes 202.

[0040] The roasting container 2 is equipped with a collecting container 12, which is provided with a collecting bin 121 for collecting coffee bean shells. The collecting bin 121 is connected to the shell discharge hole 202 and is located at the bottom of the shell discharge hole 202, so that the removed coffee bean shells can be collected by the collecting container 12.

[0041] Reference Figure 2 and Figure 3 The roasting machine body 1 is provided with an air inlet 101 and an air outlet 102. The air inlet 101 is used to blow roasting hot air into the closed receiving chamber 201, and the air outlet 102 is used to discharge the roasting hot air in the receiving chamber 201. The air inlet 101 and the air outlet 102 are located on the same side of the receiving chamber 201, so as to extend the time that the roasting hot air stays in the receiving chamber 201, thereby making full contact between the roasting hot air and the coffee beans, so that the coffee beans can be roasted more easily in a shorter time.

[0042] Specifically, in the embodiment of the present application, the air inlet 101 and the air outlet 102 are both located at the top of the storage bin 201, and the air outlet 102 is located at the center of the air inlet 101, so that the roasting hot air moves downward from the four sides of the air outlet 102 and fully contacts the coffee beans, and then moves upward toward the center to the air outlet 102 and leaves the storage bin 201, thereby ensuring that the roasting hot air roasts the coffee beans placed in the storage bin 201.

[0043] Reference Figure 2 and Figure 3The roaster body 1 is provided with an air inlet duct 103, located on a side away from the roaster body 1 and away from the container slot. The input end of the air inlet duct 103 is connected to the atmosphere, and the output end of the air inlet duct 103 is connected to the air inlet 101. An air inlet fan 13 is installed within the air inlet duct 103 to draw ambient temperature air into the air inlet duct 103. A heater 3 is fixedly mounted at the output end of the air inlet duct 103, which generates heat when powered. The heater 3, the air inlet 101, and the air outlet 102 are located on the same side of the storage bin 201. That is, in this embodiment, the heater 3 is located at the top of the storage bin 201, radiating heat from top to bottom to the coffee beans for roasting. The heater 3 also heats the ambient temperature air within the air inlet duct 103 to generate roasting hot air, thereby driving the air flow within the storage bin 201 through the air inlet fan 13.

[0044] Reference Figure 3 and Figure 4 The roaster body 1 is provided with a smoke removal chamber 104, which is located at the top of the storage bin 201. The input end of the smoke removal chamber 104 is connected to the air outlet 102, and the output end of the smoke removal chamber 104 is connected to the atmosphere. A smoke filter 14 is installed inside the smoke removal chamber 104 so that the smoke generated during the roasting process of coffee beans can be absorbed through the micropores of the smoke filter 14, thereby reducing the odor generated in the atmosphere. Figure 4 A smoke removal heating wire 15 is installed in the smoke removal chamber 104. The smoke removal heating wire 15 is located between the smoke filter 14 and the input end of the smoke removal chamber 104. The smoke removal heating wire 15 releases heat after being energized, so that the combustible particles in the smoke generated by the roasting of coffee beans and the sediment accumulated in the smoke filter 14 can be heated and burned through the smoke removal heating wire 15, thereby slowing down the speed of smoke particles accumulating in the smoke filter 14, thereby extending the service life of the smoke filter 14.

[0045] The coffee roaster according to the present embodiment of the present application operates as follows: the air intake fan 13 draws ambient temperature air into the air intake passage 103. The ambient temperature air is heated by the heater 3 to form roasting hot air. The roasting hot air enters the storage chamber 201 through the air inlet 101 and then leaves the storage chamber 201 through the air outlet 102, thereby roasting the coffee beans in the storage chamber 201. Because the air inlet 101 and the air outlet 102 are located on the same side of the storage chamber 201, the roasting hot air first blows vertically downward from the air inlet 101 toward the coffee beans. After being forced to pass through the gaps between the coffee beans and contacting the inner wall of the storage chamber 201, the roasting hot air then leaves the storage chamber 201 through the air outlet 102 in a vertically upward direction. This ensures sufficient contact between the roasting hot air and the coffee beans, thereby allowing the coffee beans to be roasted more easily and quickly with less noise.

[0046] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
