Description

Technical Field

[0001] This utility model relates to the field of coffee processing technology, specifically to a coffee roasting device with a rotating mechanism. Background Technology

[0002] Coffee roasting equipment is used to transform raw coffee beans into roasted coffee beans through heating. Its core function is to enhance the flavor, aroma, and color of the coffee beans by controlling temperature and time. Existing methods rely on hot air, which may result in uniform roasting but insufficient flavor development and a lack of complex layers. Furthermore, the roasting capacity is typically ≤200g per batch, making it inefficient and unsuitable for multiple users.

[0003] A search revealed a utility model patent with publication number CN219305984U, which discloses a coffee roasting device that effectively preserves aroma, relating to the field of coffee roasting technology. This utility model includes a machine body comprising a roasting chamber and a heating chamber, with the roasting chamber located above the machine body. A feed pipe is installed on the upper surface of the machine body, connecting to the roasting chamber. A hopper is installed at one end of the feed pipe, and an outer cylinder is installed on the inner circumferential side of the feed pipe, slidingly engaging with it. A spiral conveyor plate is fixedly installed on the inner circumferential side of the outer cylinder. This utility model, by using an outer cylinder with spiral conveyor plates, allows coffee beans to be fed into the machine body through the feed pipe. After the outer cylinder is inserted into the feed pipe, the equipment is started to roast the coffee beans. During roasting, the aroma generated is blocked by the multi-layered structure of the spiral conveyor plates, reducing its upward propagation speed. This ensures ventilation during roasting while preserving most of the aroma, preventing rapid dissipation and affecting the roasting experience.

[0004] The aforementioned patent only connects the roasting chamber through the feed pipe, uses the heating chamber to roast the coffee, and uses the multi-layer structure of the spiral conveyor to block the release of aroma substances. However, the coffee beans are stacked in the roasting chamber, which cannot fully roast each coffee bean evenly, making it difficult to achieve consistent coffee flavor. Furthermore, the efficiency of using physical methods to block the release of aroma substances is too low.

[0005] Therefore, it is necessary to invent a coffee roasting device with a rotating mechanism to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a coffee roasting device with a rotating mechanism. Through a motor, gears, pulleys, synchronous belts, and a roasting barrel, the roasting barrel rotates back and forth, ensuring even roasting of coffee beans. A nitrogen filling machine is used to protect the large number of volatile compounds produced during high-temperature roasting, preserving more of the coffee's delicate flavor. At the same time, it delays the rancidity of the oils in the coffee beans caused by oxygen, thus extending the coffee's shelf life. This solves the problems of incomplete roasting and rapid flavor loss in existing technologies.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a coffee roasting device with a rotating mechanism, comprising a support plate, a roasting chamber fixedly connected to the upper end of the support plate, a protective door fixedly connected to the side wall of the roasting chamber via hinges, a bracket fixedly connected to the upper end of the support plate, a rotating column fixedly connected to the upper end of the bracket, a roasting barrel fixedly connected to the upper end of the rotating column, a roasting barrel door fixedly connected to the side wall of the roasting barrel via hinges, two sliding grooves fixedly connected to the inner wall of the roasting barrel, and a material receiving plate slidably connected inside the two sliding grooves.

A pulley two is fixedly connected to the side wall of the rotating rod, and the synchronous belt is also sleeved on the outside of the pulley two.

[0008] Preferably, the inner wall of the baking barrel is fixedly connected with a plurality of sliding grooves, and two material support plates are slidably connected inside the plurality of sliding grooves.

Detailed Implementation

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the following will provide a more detailed description of the utility model in conjunction with the accompanying drawings.

[0026] This utility model provides, for example Figure 1-6The coffee roasting apparatus shown includes a rotating mechanism, comprising a support plate 001, a roasting chamber 101 fixedly connected to the upper end of the support plate 001, a protective door 102 fixedly connected to the side wall of the roasting chamber 101 via a hinge, a bracket 201 fixedly connected to the upper end of the support plate 001, a rotating column 202 fixedly connected to the upper end of the bracket 201, a roasting barrel 203 fixedly connected to the upper end of the rotating column 202, a roasting barrel door 204 fixedly connected to the side wall of the roasting barrel 203 via a hinge, two sliding grooves 205 fixedly connected to the inner wall of the roasting barrel 203, a material receiving plate 206 slidably connected inside the two sliding grooves 205, and a heater fixedly connected through the interior of the roasting chamber 101. 301; A motor 302 is fixedly connected inside the baking oven 101. The output end of the motor 302 is fixedly connected to a gear 303 via a coupling. A gear 304 is fixedly connected to the upper end of the gear 303. A rotating rod 305 is rotatably connected to the inner wall of the baking oven 101. A gear 306 is fixedly connected to the side wall of the rotating rod 305. The gear 306 intermittently meshes with the gear 304 and the tooth grooves on the inner wall of the gear 303. A pulley 307 is fixedly connected to the side wall of the rotating rod 305. A synchronous belt 308 is sleeved on the outside of the pulley 307. A pulley 309 is fixedly connected to the side wall of the rotating column 202. The synchronous belt 308 is simultaneously sleeved on the pulley 309. Located outside pulley 309, when coffee beans need to be roasted, the protective door 102 is opened, followed by the roasting barrel door 204. The receiving plate 206 is pulled out, and coffee beans are poured onto the top of the receiving plate 206. The receiving plate 206 is then held and slid within the slide 205. The roasting barrel door 204 and protective door 102 are then closed, and the heater 301 is turned on to roast the coffee beans. The drive motor 302, a servo motor (model MHMD082P1U), drives the gear 303 to rotate. The rotation of the gear 303 drives the gear 304 to rotate. 3. Gear 1 304 drives gear 2 306 to rotate in both directions. Gear 2 306 rotates in both directions, which in turn drives rotating rod 305 to rotate in both directions. Rotating rod 305 rotates in both directions, which in turn drives pulley 1 307. Under the action of synchronous belt 308, pulley 1 307 rotates in both directions, which in turn drives pulley 2 309 to rotate in both directions. Pulley 2 309 rotates in both directions, which in turn drives roasting barrel 203 to rotate in both directions. Roasting barrel 203 rotates in both directions, which in turn drives slide 1 205 to rotate in both directions. Slide 1 205 rotates in both directions, which in turn drives material receiving plate 1 206 to rotate in both directions, thereby causing the coffee beans to be heated evenly and roasted evenly.

[0027] The inner wall of the roasting barrel 203 is fixedly connected with multiple sliding grooves 207. Two material support plates 208 are slidably connected inside the multiple sliding grooves 207. When a large number of coffee beans need to be roasted, the two material support plates 208 are pulled out, and the coffee beans are poured onto the upper part of the two material support plates 208. Then, the two material support plates 208 are slid inside the multiple sliding grooves 207, which can roast a large number of coffee beans and improve the roasting efficiency of coffee beans.

[0028] A nitrogen filler 401 is fixedly connected to the upper end of the support plate 001. An exhaust pipe 402 is fixedly connected through the inside of the roasting chamber 101, and the exhaust pipe 402 is connected to the inside of the input end of the nitrogen filler 401. A connecting pipe 403 is fixedly connected through the inside of the roasting chamber 101, and the connecting pipe 403 is connected to the output end of the nitrogen filler 401. An outlet 404 is fixedly connected to the side wall of the connecting pipe 403. When roasting coffee beans, the nitrogen filler 401 is started. The nitrogen filler 401 draws air through the exhaust pipe 402. After compression, purification, gas separation and purification by the nitrogen filler 401, the air is pumped into the connecting pipe 403 through the output end, enters the outlet 404 through the connecting pipe 403, and is blown out through the outlet 404 to perform nitrogen filling treatment on the coffee beans. This protects the large number of volatile compounds produced by the coffee beans during high-temperature roasting, retains more of the delicate flavor of the coffee, and delays the process of rancidity caused by the oils in the coffee beans under the action of oxygen, thus extending the shelf life of the coffee.

[0029] Multiple fans 405 are fixedly connected to the top wall of the roasting oven 101, and multiple fans 406 are fixedly connected to the side wall of the roasting oven 101. After the heater 301 is turned on, multiple fans 405 and 406 are turned on. The fans 405 and 406 blow air to form a circulating air duct, so as to keep the internal temperature of the roasting oven 101 uniform and roast the coffee beans evenly inside the roasting oven 101.

[0030] The interior of the roasting oven 101 is fixedly connected to an air vent 104, and the side wall of the protective door 102 is fixedly connected to an observation glass 103. During roasting, carbon dioxide fumes and volatile organic compounds are discharged through the air vent 104 to prevent them from accumulating inside the cavity and affecting the flavor. During roasting, the coffee beans inside the roasting oven 101 can be observed through the observation glass 103.

[0031] Multiple support columns 105 are fixedly connected to the lower end of the support plate 001. The multiple support columns 105 support the device and ensure the stability of the device during operation.

[0032] The practical working principle is as follows: When coffee beans need to be roasted, open the protective door 102, then open the roasting barrel door 204, pull out the feed plate 206, pour the coffee beans onto the feed plate 206, then hold the feed plate 206 and slide it inside the slide groove 205. Then close the roasting barrel door 204 and the protective door 102, turn on the heater 301 to heat and roast the coffee beans, and drive the motor 302. The motor 302 is a servo motor, model MHMD082P1U. The output of the motor 302 drives the gear 303 to rotate, and the rotation of the gear 303 drives the gear 304 to rotate. The gear 303 and... Gear 1 304 drives gear 2 306 to rotate in both directions. The rotation of gear 2 306 drives rotating rod 305 to rotate in both directions. The rotation of rotating rod 305 drives pulley 1 307. Under the action of synchronous belt 308, pulley 1 307 rotates in both directions, which drives pulley 2 309 to rotate in both directions. The rotation of pulley 2 309 drives roasting barrel 203 to rotate in both directions. The rotation of roasting barrel 203 drives chute 1 205 to rotate in both directions. The rotation of chute 1 205 in turn drives material support plate 1 206 to rotate in both directions, thereby causing the coffee beans to be heated evenly and roasted evenly.

[0033] During coffee bean roasting, the nitrogen filling machine 401 is started. The nitrogen filling machine 401 draws in air through the air extraction pipe 402. After compression, purification, gas separation and purification by the nitrogen filling machine 401, the air is pumped into the connecting pipe 403 through the output end, and then enters the second air outlet 404 through the connecting pipe 403. The air is then blown out through the second air outlet 404 to perform nitrogen filling treatment on the coffee beans. This protects the large number of volatile compounds produced by the coffee beans during high-temperature roasting, retains more of the delicate flavor of the coffee, and at the same time delays the process of rancidity caused by the oils in the coffee beans under the action of oxygen, thus extending the shelf life of the coffee.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
