Description

Technical Field

[0001] This utility model relates to the field of coffee roasting equipment technology, and in particular to a small and lightweight coffee roaster. Background Technology

[0002] With the rise of the third wave of coffee (emphasizing coffee origin, roasting process, and flavor details), consumers' demands for coffee quality have shifted from "convenience" to "personalization" and "freshness." Home roasting can preserve the flavor of coffee beans to the greatest extent, satisfying the demand for the ultimate experience.

[0003] Traditional coffee roasting equipment typically consists of large drum or hot air roasters, which are quite bulky, comparable to a washing machine (a 30kg model can occupy over 1.5 square meters), and require dedicated ventilation and exhaust systems. Furthermore, traditional roasters are complex to operate and expensive. Coffee enthusiasts without professional training often find it difficult to roast coffee on their own.

[0004] Although there are some small coffee roasters available, their ability to collect the silver crust and treat the fumes produced during roasting is still insufficient. Furthermore, the oils produced during coffee roasting are difficult to clean, which poses a significant challenge to the entry of coffee roasting equipment into the home market. Utility Model Content

[0005] This invention primarily addresses the technical problems of traditional coffee roasting equipment, such as its large size, the need for dedicated ventilation and smoke extraction systems, and the inconvenience of collecting grease and oil in small coffee roasters. It proposes a small, lightweight coffee roaster to achieve miniaturization and weight reduction of the entire machine, while also facilitating cleaning and maintenance.

[0006] This utility model provides a small and lightweight coffee roaster, including: a body, a silver storage component, and a roasting component, a heat insulation component, and a fan component disposed in the body;

[0007] The silver leather storage assembly is detachably mounted on the device body; the silver leather storage assembly includes: a silver leather box lid and a silver leather storage box; the silver leather box lid is detachably mounted on the silver leather storage box; a box lid mesh is provided on the silver leather box lid; the silver leather storage box has a central opening, and the area around the opening of the silver leather storage box protrudes upwards; a silver leather storage box mesh is provided on the side wall of the silver leather storage box;

[0008] The baking assembly includes: a baking liner; the top of the baking liner is open, and the lower side wall of the baking liner has a plurality of circumferentially arranged spinning openings;

[0027] The small, lightweight coffee roaster provided by this utility model has the following advantages compared with the prior art:

[0028] 1. This utility model adopts an integrated modular design, highly integrating functional modules to achieve miniaturization and lightweighting of the entire machine. The compact and highly integrated design results in fewer parts, with many resin components featuring a snap-fit ​​design, simplifying the structure, facilitating installation, disassembly, and cleaning / maintenance. The resin material can be directly rinsed and is easy to clean.

[0029] 2. Traditional coffee roasters typically use metal bodies due to their high operating temperatures. However, the main components of this invention are primarily made of resin and aluminum, achieving significant weight reduction. Through high-temperature sealing and optimized airflow, hot air bypasses the machine chamber, minimizing the impact of high temperatures on the resin materials. The machine body temperature remains low, preventing burns during use.

[0030] 3. During roasting, the heating plate heats up, and the motor drives the fan impeller to blow air through the swirling openings, ensuring efficient heat transfer to the roasting chamber. The airflow also promotes even roasting of the coffee beans. After roasting, the heating plate is turned off, and the motor drives the fan impeller to cool the coffee beans with natural airflow, preserving their flavor. A single fan simultaneously performs both hot air roasting and cooling functions.

[0031] 4. The top of the baking liner and the middle opening of the lid are connected to the middle opening of the silver foil storage box, forming a silver foil channel. Both the silver foil box lid and the silver foil storage box have mesh grilles, creating an airflow direction from bottom to top and then outwards. The lighter silver foil in the baking liner falls into the silver foil storage box with the airflow, making it easy to collect the silver foil.

[0032] 5. The silver foil storage unit is detachable and can be installed on the machine body. After roasting, the roasted coffee beans can be poured out by opening the silver foil storage unit. The silver foil storage unit can be rinsed directly for easy cleaning. Attached Figure Description

It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the accompanying drawings, not all of them.

[0038] like Figure 1-3 As shown in the figure, the present invention provides a small and lightweight coffee roaster, including: a body 17, a silver storage component, and a roasting component, a heat insulation component, and a fan component disposed in the body 17.

[0039] The silver foil storage component is detachably mounted on the body 17. Specifically, a top cover 5 is provided on the top of the body 17 and the baking liner 6. The top cover 5 is fixed to the body 17 by screws. The top cover 5 has an opening in the middle, allowing the silver foil to pass through. The silver foil storage box 4 is fastened to the top cover 5, making the silver foil storage component detachable. The silver foil storage component can be removed from the top cover 5.

[0040] The silver foil storage assembly includes a silver foil lid 1 and a silver foil storage box 4. The silver foil lid 1 is detachably mounted on the silver foil storage box 4. Specifically, the silver foil lid 1 and the silver foil storage box 4 are equipped with matching threaded structures, allowing them to be opened and closed by screwing. The silver foil lid and the silver foil storage box are made of high-temperature resistant resin material. A lid mesh 7 is provided on the silver foil lid 1. A glass window is provided on the silver foil lid 1, and the lid mesh 7 is specifically located on the outer periphery of the glass window. Specifically, a window opening is provided on the silver foil lid 1, and a glass pressure plate 3 fixes the quartz glass 2 in the window opening. The lid mesh 7 can be formed by steel wire mesh, which is integrally injection molded with the silver foil lid 1, making it less likely to trap dust and silver foil; alternatively, a steel wire frame combined with a filter screen can be used to reduce smoke pollution.

[0041] The silver storage box 4 has a central opening that allows silver sheets to pass through; the area around the opening of the silver storage box 4 protrudes upwards, forming a silver sheet compartment where the silver sheets fall in, facilitating storage. The protrusion of the silver storage box 4 also allows the top cover 5 of the body 17 to be embedded. The side wall of the silver storage box 4 has a silver storage box mesh 9; the silver storage box mesh 9 can be formed of wire mesh, integrally injection molded with the silver storage box 4, making it less likely to trap dust or silver sheets; alternatively, a wire frame combined with a filter can be used to reduce smoke pollution. The silver storage box mesh 9 and the lid mesh 7 allow airflow, facilitating the flow of lighter silver sheets into the silver storage box 4.

[0042] The roasting assembly includes: a roasting liner 6; the roasting liner 6 has an open top and multiple circumferentially arranged spinning openings 22 on the lower side wall. Coffee beans are placed in the roasting liner 6. The spinning openings 22 open diagonally downwards against the direction of fan rotation to allow efficient airflow into the roasting liner 6. An annular protrusion 23 is provided above the spinning openings 22 of the roasting liner 6. The annular protrusion 23 is used to engage with the central opening of the heat insulation cover 8. The annular protrusion 23 fits tightly with the heat insulation cover 8, enhancing heat insulation performance and improving airflow utilization. The annular protrusion 23 can be formed by stamping; correspondingly, the annular protrusion 23 manifests as an annular groove inside the roasting liner 6, serving as a marker line for placing coffee beans. The roasting liner 6 is made of aluminum, making it lighter than stainless steel devices.

[0043] The thermal insulation component includes: a thermal insulation cover 8 and a heating plate 10; the thermal insulation cover 8 adopts an inverted barrel-shaped structure, and the top of the thermal insulation cover 8 has an opening in the middle. A baking liner 6 is inserted into the opening of the thermal insulation cover 8, so that multiple spun openings 22 are located inside the thermal insulation cover 8. The bottom of the thermal insulation cover 8 has a flanged structure for easy fixing to the fan assembly. The thermal insulation cover 8 is made of aluminum.

[0044] The heating plate 10 is disposed inside the heat insulation cover 8 and is located below the baking liner 6. The heating plate 10 is fixed to the heat insulation cover 8 by a heating plate fixing ring 11. The heating element on the heating plate 10 is a heating wire or a ceramic heating tube, and a circular heating plate can be used. The outer diameter of the heating plate 10 is slightly smaller than the inner diameter of the heat insulation cover 8. The bottom of the heating plate fixing ring 11 also has a flanged structure, which corresponds to the flanged structure of the heat insulation cover 8. Specifically, the flanged structures of the heat insulation cover 8 and the heating plate fixing ring 11 are fixed together with the fan housing 13, which can be fixed by a set of screws, reducing the number of screws used.

[0045] The inner wall of the thermal insulation cover 8 is provided with a first heat insulation ring, and the flanged structure of the thermal insulation cover 8 is provided with a second heat insulation ring; the first and second heat insulation rings can be made of flexible mica sheets. The first heat insulation ring can reduce the loss of heat from the hot air temperature, allowing less heat to be transferred to the surface of the body 17, thus lowering the surface temperature of the body 17 and preventing burns. The second heat insulation ring is in close contact with the flanged position of the thermal insulation cover 8, isolating the thermal insulation cover 8 from the fan assembly below, reducing the damage to the fan assembly caused by heat conduction.

[0046] The fan assembly is positioned below the thermal insulation component. The fan assembly includes a fan, a motor 15, and a motor housing 14; the fan includes a fan housing 13 and a fan impeller 12 mounted on the fan housing 13. The fan impeller 12 has multiple blades evenly arranged circumferentially. The fan housing 13 and the fan impeller 12 are made of resin material.

[0047] The fan is mounted on the shaft of the motor 15, which is housed in a motor cover 14. The motor cover 14 has a round support structure, housing the motor 15. A guide post structure 21 is provided below the motor cover 14. The motor cover 14 is fixedly connected to the bottom shell 19 of the body 17 via the guide post structure 21. An electrical compartment is provided between the motor cover 14 and the bottom shell 19, and a circuit board is fixedly installed inside the electrical compartment. The circuit board can be fitted with holes in the motor cover 14 and the bottom shell 19 for fixation. The circuit board is fixed to the motor cover 14 via an upper PCB fixing plate 16 and to the bottom shell 19 via a lower PCB fixing plate.

[0048] In addition, the body 17 has a U-shaped opening, through which the body 17 is snapped into the handle 18. The handle 18 is assembled with a snap-fit ​​design for easy disassembly and maintenance. The body 17 has an operation panel 20, which can be a touch screen or buttons. The body 17 is made of resin material.

[0049] The working principle of the small and lightweight coffee roaster provided by this utility model is as follows: During roasting, appropriate raw coffee beans are placed in the roasting chamber 6. After the power is turned on, the heating plate 10 is heated. Because the roasting chamber 6 and the heat insulation cover 8 are designed to form a sealed state, the motor 15 rotates to drive the fan impeller 12 to blow air. Through the swivel opening 22, the heat of the heating plate 10 can be efficiently conducted into the roasting chamber 6. And through the airflow disturbance, the coffee can be roasted evenly in the roasting chamber 6.

[0050] The top of the baking liner 6 is open in the middle with the top cover 5 and the middle of the silver storage box 4, forming a silver channel. Both the silver box cover 1 and the silver storage box 4 have mesh grilles, which create an airflow direction from bottom to top and then outwards. The lighter silver pieces in the baking liner 6 fall into the silver storage box 4 with the airflow.

[0051] After roasting, the heating plate 10 is turned off, and the motor 15 rotates to drive the fan impeller 12 to cool the coffee beans with natural air, thus preserving their flavor. A single fan simultaneously performs both hot air roasting and cooling functions.

[0052] After roasting, open the silver foil storage unit and pour out the roasted coffee beans. Rinse the silver foil storage unit again to complete one roasting cycle.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications to the technical solutions described in the foregoing embodiments, or equivalent substitutions for some or all of the technical features, do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
