Description

Technical Field

[0001] This utility model relates to the field of coffee bean processing technology, specifically to a coffee bean sorting and roasting device. Background Technology

[0002] Coffee beans are classified as washed or dried, and as flat or round beans. Coffee beans vary in color, and through dark roasting, they burst open, doubling in size. During roasting, volatile flavor oils are gradually generated, achieving a perfect balance of flavors. Different sizes of coffee beans also produce different flavors after roasting, thus requiring sieving.

[0003] Patent No. CN219813151U discloses a coffee bean sorting and roasting device, relating to the field of coffee bean processing technology. The device includes a base with a circular array of connecting springs on the top. The top of the connecting springs is fixedly connected to the bottom of a sorting cylinder. A vibration motor is fixedly connected to the side of the sorting cylinder. A discharge tray is fixedly connected to the bottom of the inner cavity of the sorting cylinder. The top of the discharge tray is set as an inclined surface. A sorting component with an adjustable coffee bean sorting diameter is provided inside the sorting cylinder. A support foot is fixedly connected to the side of the base away from the sorting cylinder, and a receiving cylinder is provided on the top of the support foot. The structure of this utility model that performs the sorting function consists of a movable mesh tray, a fixed mesh tray, and locking bolts. By matching the apertures on the movable and fixed mesh trays, the desired sorting diameter of coffee beans can be instantly formed. Compared with traditional sorting machines that require disassembly and replacement of the sorting mesh, this method is simple to operate and takes less time. The above solution uses a roasting pan to roast the sorted coffee beans. Since no cooling component is provided, the residual heat of the roasting pan will continue to heat the roasted coffee beans after roasting, which can easily lead to over-roasting of the coffee beans, which can seriously damage the flavor and aroma of the coffee beans. Therefore, we propose a coffee bean sorting and roasting device. Utility Model Content

[0004] The purpose of this invention is to provide a coffee bean sorting and roasting device to solve the problem mentioned in the background art, where the residual heat of the roasting pan continues to heat the roasted coffee beans after roasting due to the lack of a cooling component, which can easily lead to over-roasting of the coffee beans and seriously damage their flavor and aroma.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a coffee bean sorting and roasting device, including a base, a roasting pot, and a discharge pipe, and further including an air outlet component, a cooling component, and a dust removal component. The air outlet component is installed at the bottom of the base, the cooling component is installed above the roasting pot, and the dust removal component is installed on the surface of the discharge pipe. When the air outlet component and the cooling component are connected, they cool the roasted coffee beans.

[0006] Preferably, the air outlet assembly includes a housing, an air outlet duct, an air intake fan, a fixing plate, and a dustproof net. The housing is fixedly connected to the bottom of the base, the fixing plate is fixedly connected inside the housing, the air intake fan is embedded inside the fixing plate, and the dustproof net is embedded at the bottom of the housing below the air intake fan.

[0007] Preferably, the cooling assembly includes a straight pipe, a first conduit pipe, and a transition pipe. The straight pipe is fixedly connected to the top of the baking pan. The top of the straight pipe is connected to the transition pipe through the first conduit pipe, and the other end of the transition pipe is connected to the air outlet pipe.

[0008] Preferably, the dust removal assembly includes a second guide tube, a rubber block, a filter screen, and a frame. The second guide tube is inserted into the top of the discharge pipe, and a rubber block is provided at the contact position between the second guide tube and the discharge pipe. A frame is fixedly connected to the bottom of the discharge pipe below the second guide tube. Equally spaced fine grooves are provided at the top of the frame and the contact position between the frame and the discharge pipe. A filter screen is inserted through the side of the frame.

[0009] Preferably, the other end of the second conduit is connected to the transition tube, and both the second and the first conduit are equipped with a solenoid valve at the end near the transition tube. The inner diameters of the second and the first conduit are the same.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model has an air intake fan installed in the housing at the bottom of the base. The solenoid valve on the surface of the first duct is opened and the solenoid valve on the surface of the second duct is closed. Air is sent into the air outlet pipe through the air intake fan. After passing through the transition pipe to the first duct, natural air is output through the straight pipe.
