Detailed Implementation

[0040] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0041] Example 1

[0042] like Figures 1-5As shown, this embodiment includes an airflow chamber 100 and an airflow channel 200 disposed on the top of the airflow chamber 100; the airflow chamber 100 includes a transverse airflow cavity 101 and a longitudinal airflow cavity 102 that are connected, and the height of the longitudinal airflow cavity 102 is higher than the height of the transverse airflow cavity 101; in this embodiment, the airflow channel 200 is disposed on the top of the longitudinal airflow cavity 102, specifically, the middle part of the airflow channel 200 is fixedly disposed on the top of the exterior of the longitudinal airflow cavity 102.

[0043] like Figure 6 As shown, the airflow channel 200 includes a first annular chamber 201, a second annular chamber 202, and a connecting channel 203 connecting the first annular chamber 201 and the second annular chamber 202; and the middle part of the connecting channel 203 is fixedly disposed on the outside of the longitudinal airflow cavity 102.

[0044] The airflow chamber 100 is equipped with a heating chamber 300 that communicates with the airflow chamber 100. In this embodiment, the heating chamber 300 is vertically arranged in the transverse airflow cavity 101. The heating chamber 300 is equipped with a fan 310, a heater 320, a cyclone chamber 330, and a temperature sensor 340. The temperature sensor 340 is used to monitor the temperature change inside the cyclone chamber 330 in real time. Thus, through the operation of the fan 310, the heat in the airflow chamber 100 can be negatively compressed into the heating chamber 300. At the same time, the heater 320 heats the air and generates hot air, which then enters the cyclone chamber 330. This allows the heat in the airflow chamber 100 to be negatively compressed into the heating chamber 300 to achieve heat recovery and also cools the airflow chamber 100. In addition, the hot air inside the cyclone chamber 330 is monitored by the temperature sensor 340 and fed back to the power control module 500 (described in detail below), thereby adjusting the working state of the heater 320 according to the actual temperature requirements and achieving precise temperature control.

[0045] The airflow chamber 100 is also equipped with a power control module 500. In this embodiment, the power control module 500 is arranged in the longitudinal airflow cavity 102 and is arranged in parallel with the heating chamber 300. The power control module 500 is electrically connected to the fan 310, the heater 320 and the temperature sensor 340. The power control module 500 is used to receive the temperature data transmitted by the temperature sensor 340 and automatically adjust the working state of the heater 320 according to the preset temperature range, thereby realizing closed-loop control of the hot air temperature.

[0046] In this embodiment, the heat generated by the power control module 500 can be negatively compressed into the heating chamber 300 by the operation of the fan 310, thereby realizing the heat energy recovery in the airflow chamber 100.

[0047] The heating chamber 300 is connected to the baking chamber 400. The top of the baking chamber 400 is connected to the first end of the airflow channel 200. The second end of the airflow channel 200 is connected to the cyclone filter 450. An air outlet 210 is provided on the second end of the airflow channel 200. One end of the air outlet 210 is exposed at the top of the cyclone filter 450. A material collection bucket 410 is provided at the bottom of the cyclone filter 450.

[0048] In this embodiment, the baking chamber 400 is located at the top outside the transverse airflow chamber 101 and communicates with the transverse airflow chamber 101, and the airflow channel 200 is located at the top of the longitudinal airflow chamber 102; the top of the baking chamber 400 communicates with the first annular chamber 201, and the cyclone filter 450 is located below the second annular chamber 202 and communicates with the second annular chamber 202; the material collection bucket 410 is located at the bottom of the cyclone filter 450; at the same time, the air outlet 210 is located at the top of the second annular chamber 202 and communicates with the cyclone filter 450.

[0049] A feeding funnel 220 is provided on the top of the baking chamber 400 and on the airflow channel 200, and a baffle hammer 230 is provided inside the feeding funnel 220. In this embodiment, the baffle hammer 230 includes a flow-around rod extending into the baking chamber 400, thereby improving the contact efficiency between hot air and materials through the setting of the baffle hammer 230, thereby achieving efficient drying or baking.

[0050] In one embodiment, the rotation of the turbulence hammer 230 can also initially disperse the material, making it easier for it to come into full contact with the hot air after entering the baking chamber 400, thereby improving the heat exchange efficiency.

[0051] In this embodiment, the turbulence hammer 230 is detachably installed inside the feed hopper 220.

[0052] In one embodiment, a feed channel exists between the feed hopper 220 and the turbulence hammer 230.

[0053] In one embodiment, the turbulence hammer 230 is capable of covering and sealing the feed hopper 220.

[0054] Therefore, the hot air generated by the heating chamber 300 can enter the roasting chamber 400 through the cyclone chamber 330 to evenly heat the coffee beans in the roasting chamber 400. At the same time, the baffle hammer 230 continuously operates to ensure that the coffee beans are heated evenly during the roasting process, avoiding local overheating that could lead to scorching or uneven roasting. During the roasting process, the temperature sensor 340 monitors the temperature changes in the cyclone chamber 330 in real time and feeds the data back to the power control module 500. By adjusting the working status of the fan 310 and the heater 320, precise control of the roasting temperature can be achieved.

[0055] When the coffee beans reach the preset roasting level, the power control module 500 increases the speed of the fan 310, causing the coffee beans and hot air in the roasting chamber 400 to enter the first annular chamber 201 and then the second annular chamber 202 through the connecting channel 203. The mixture is then conveyed to the cyclone filter 450 for separation. The cyclone filter 450 utilizes the centrifugal force generated by the high-speed airflow to efficiently separate the coffee beans from the hot air, avoiding the clogging problems caused by traditional screen filtration and improving separation efficiency. The separated coffee beans fall directly into the material collection bin 410 at the bottom of the cyclone filter 450 for collection; while the hot air is discharged through the air outlet 210, thus completing the roasting of the coffee beans.

[0056] In this embodiment, the air outlet 210 is connected to a smoke remover, which includes a smoke extraction fan, a smoke heater, a smoke sensor, and a catalyst; thus, hot air and smoke enter the smoke remover through the air outlet 210 for smoke removal.

[0057] In this embodiment, a housing is also included, and the airflow chamber 100, airflow channel 200, heating chamber 300, baking chamber 400, and cyclone filter 450 are all disposed inside the housing, forming a compact and functionally integrated baking device.

[0058] In this embodiment, the bottom of the housing is provided with support feet, which are evenly distributed around the bottom of the housing to ensure the overall stability and balance of the equipment. At the same time, the bottom of the support feet is provided with anti-slip pads to reduce vibration and noise during equipment operation and prevent the equipment from sliding and causing safety hazards. The height of the support feet is adjustable to adapt to different ground conditions and ensure that the equipment is in a horizontal state, thereby ensuring the normal operation of the internal components.

[0059] In this embodiment, a control panel is provided on the housing, which is connected to the power control module 500 for setting and monitoring roasting parameters. The control panel allows setting key parameters such as roasting temperature, time, and fan speed (310 rpm), and displays the current operating status and temperature curve in real time, facilitating precise monitoring of the roasting process by the operator. Furthermore, the control panel has a self-diagnostic function, automatically providing alarm information when equipment malfunctions, ensuring stable operation. The entire roasting process is highly automated and easy to operate, suitable for the personalized roasting needs of different types of coffee beans, significantly improving production efficiency and consistency of finished product quality. Further, to enhance the applicability and stability of the equipment...

[0060] An air inlet 110 is provided on the side of the airflow chamber 100 facing the baking chamber 400. The fan 310 is used to draw outside air through the air inlet 110, the heating chamber 300, the baking chamber 400 and the airflow channel 200 in sequence. At the same time, the air inlet 110 can also absorb the heat on the outer surface of the baking chamber 400, so that the outer surface of the baking chamber 400 can also dissipate heat and achieve heat recovery.

[0061] In this embodiment, the air inlet 110 is located on the side of the longitudinal airflow cavity 102 facing the baking chamber 400. The air inlet 110 allows external air to enter the airflow cavity 100 smoothly, providing a continuous source of fresh air for the airflow circulation system, thereby ensuring the stability and flow of airflow during the baking process and avoiding temperature fluctuations or local heat accumulation caused by poor airflow.

[0062] In this embodiment, a filter device is provided at the air inlet 110 to remove impurities and dust that may be carried in the air, ensuring that the airflow entering the roasting chamber 400 is clean and avoiding secondary contamination of the coffee beans.

[0063] In this embodiment, an illumination lamp 550 is also provided in the airflow chamber 100. The illumination lamp 550 is connected to the power control module 500 and is located on one side of the air inlet 110, so that the baking chamber 400 can be illuminated through the air inlet 110.

[0064] In this embodiment, the roasting chamber 400 is a transparent glass roasting chamber; thus, the lighting 550 not only improves the visibility of the equipment, making it easier for operators to observe the roasting status and color changes of the coffee beans, but also helps to adjust the roasting parameters in a timely manner to ensure that the coffee beans achieve the ideal roasting effect. The combination of a visual operating interface and real-time lighting further enhances the human-computer interaction experience of the equipment, making the entire roasting process more intuitive and controllable, and enhancing the accuracy and convenience of operation.

[0065] Because the transparent glass window on the baking machine is easily stained by smoke and oil produced during baking after a period of use, disassembling and cleaning the glass window requires disassembling the machine, and the process is complicated.

[0066] In this embodiment, the baking chamber 400 is detachably connected to the airflow chamber 100 and the airflow channel 200 via a disassembly mechanism; this facilitates regular cleaning or replacement of the transparent glass window by operators, preventing smoke residue and oil stains from affecting the observation effect.

[0067] like Figures 7-12As shown, the disassembly mechanism includes an annular assembly and an annular clamping member 600. The annular clamping member 600 is threadedly connected to the inner ring of the annular assembly. The roasting chamber 400 is located below the annular clamping member 600. In this embodiment, the roasting chamber 400 is located inside the annular assembly. Thus, by rotating the annular clamping member 600 and the annular assembly threadedly, the annular clamping member 600 can press the roasting chamber 400 or move away from the roasting chamber 400. This allows the roasting chamber 400 to be disassembled from the annular clamping member 600 and the annular assembly, thereby removing the roasting chamber 400 from the roasting machine for cleaning. This prevents the transparent glass roasting chamber 400 from being contaminated by smoke and oil stains generated during roasting after a period of use, which would affect the observation of the roasting status of the coffee beans.

[0068] In this embodiment, a tightening plate 650 is also included, and a tightening block 651 perpendicular to the tightening plate 650 extends from the first end of the tightening plate 650; in this embodiment, there are two tightening blocks 651, and the tightening blocks 651 are cylindrical.

[0069] The annular clamping member 600 has at least one groove 601; and the tightening block 651 is adapted to the groove 601; thus, by holding the tightening plate 650 and inserting the two tightening blocks 651 on the tightening plate 650 into the two grooves 601 on the annular clamping member 600, and then by rotating the tightening plate 650, the tightening plate 650 is connected to the groove 601 through the tightening blocks 651 and achieves a fixing effect, which can make the annular clamping member 600 press against the baking chamber 400 or move away from the baking chamber 400; thus realizing the disassembly of the baking chamber 400 from the annular clamping member 600 and the annular assembly, and at the same time preventing the baking chamber 400 on the baking machine from being contaminated by smoke and oil stains generated during baking after a period of use.

[0070] like Figure 11 As shown, the annular clamping member 600 includes an integrally formed upper ring 610 and a lower ring 620. The outer diameter of the upper ring 610 is smaller than the outer diameter of the lower ring 620. The upper ring 610 is threadedly connected to the annular assembly. In this embodiment, the outer ring of the upper ring 610 is provided with an external thread. The groove 601 is two cylindrical through slots, which are provided on the lower ring 620 and vertically penetrate the lower ring 620. At the same time, the groove 601 is formed on the lower ring 620 and away from the center of the lower ring 620. Then, by holding the tightening plate 65 by hand... 0, so that the tightening block 651 on the tightening plate 650 is inserted into the groove 601, and by rotating the tightening plate 650, the tightening plate 650 is connected to the groove 601 through the tightening block 651 and achieves a fixing effect, which enables the annular clamping member 600 to press against the baking chamber 400 or move away from the baking chamber 400; realizes the disassembly of the baking chamber 400 on the annular clamping member 600 and the annular assembly, and at the same time prevents the baking chamber 400 on the baking machine from being contaminated by smoke and oil stains generated during baking after a period of use.

[0071] The annular clamping member 600 has a clamping groove 602 on the side facing the baking chamber 400 that matches the top of the baking chamber 400. In this embodiment, the clamping groove 602 is located at the bottom of the lower ring 620. The clamping groove 602 creates a convex through groove in the inner ring of the annular clamping member 600. The annular clamping member 600 can be screwed onto or moved away from the baking chamber 400 by the threaded rotation of the annular clamping member 600 and the annular assembly. This allows the top of the baking chamber 400 to be located within the clamping groove 602, enabling the disassembly of the baking chamber 400 from the annular clamping member 600 and the annular assembly.

[0072] In one embodiment, the diameter of the clamping groove 602 gradually decreases from the bottom of the annular clamping member 600 toward the top of the annular clamping member 600.

[0073] A first silicone pad is provided in the pressing groove 602. In this embodiment, the first silicone pad is an annular silicone pad. Thus, when the annular pressing member 600 and the annular assembly rotate threadedly to press the annular pressing member 600 against the baking chamber 400, the first silicone pad can seal the annular pressing member 600 against the top of the baking chamber 400.

[0074] like Figure 10 As shown, the annular assembly includes a base 710, an upper seat 720, and a connecting post 730 connecting the base 710 and the upper seat 720. In this embodiment, both the base 710 and the upper seat 720 are annular base 710 and annular upper seat 720. The outer ring of the annular base 710 and the outer ring of the annular upper seat 720 are fixedly connected by two symmetrical connecting posts 730, and the inner ring of the upper seat 720 is provided with an internal thread that matches the external thread of the upper ring 610. This allows the external thread of the annular clamping member 600 to be threadedly connected to the internal thread of the upper seat 720, thereby enabling the annular clamping member 600 to rotate on the upper seat 720 and achieve the lifting and lowering movement of the annular clamping member 600 on the upper seat 720.

[0075] In this embodiment, the upper seat 720 is fixedly connected to the airflow channel 200, and the base 710 is fixedly connected to the airflow chamber 100. That is, the upper seat 720 is connected to the first end of the airflow channel 200, and the base 710 is connected to the transverse airflow cavity 101 of the airflow chamber 100, so that the baking chamber 400 is detachably connected to the airflow chamber 100 and the airflow channel 200 through the disassembly mechanism.

[0076] The baking chamber 400 is located on the base 710; thus, by placing the baking chamber 400 on the base 710, the annular clamping member 600 is pressed against or moved away from the baking chamber 400 by rotating the annular clamping member 600 with the glass upper seat 720.

[0077] In this embodiment, the base 710 is provided with a receiving groove 711 that matches the bottom of the baking chamber 400; thus, by setting the receiving groove 711, the baking chamber 400 can be conveniently placed while also restricting the position of the baking chamber 400 on the base 710.

[0078] In this embodiment, a lower silicone pad is provided in the receiving groove 711, and the diameter of the receiving groove 711 is larger than the diameter of the baking chamber 400; thus, the lower silicone pad can prevent the baking chamber 400 from moving when pressed against the annular clamping member 600, and at the same time, it can also make the annular clamping member 600 and the baking chamber 400 press together better.

[0079] Example 2

[0080] The difference between this embodiment and Embodiment 1 is that:

[0081] The airflow chamber 100 has a receiving cavity at the top, the baking chamber 400 is located in the receiving cavity, and the air inlet 110 is located on the inner wall of the receiving cavity and communicates with the airflow chamber 100.

[0082] In this embodiment, the receiving cavity is an open receiving cavity, so that the receiving cavity can communicate with the outside.

[0083] In this embodiment, there is an air intake space between the baking chamber 400 and the receiving cavity, so that the air inlet 110 can introduce the heat around the baking chamber 400 into the airflow chamber 100 from all directions, thereby achieving better heat recovery and utilization.

[0084] Example 3

[0085] like Figure 13 As shown, a method for controlling a coffee roaster includes the following coffee bean roasting process steps;

[0086] S1, put the coffee beans to be roasted into the feeding funnel 220, and start the fan 310 through the power control module 500 so that the outside air passes through the air inlet 110, the heating chamber 300, the roasting chamber 400 and the airflow channel 200 in sequence.

[0087] Specifically, coffee beans to be roasted are fed into the feeding funnel 220, and after being evenly dispersed by the baffle 230, they enter the roasting chamber 400. The power control module 500 starts the fan 310 so that outside air passes through the air inlet 110, the heating chamber 300, the roasting chamber 400, and the airflow channel 200 in sequence. Specifically, the power control module 500 starts the fan 310 and the heater 320. The heater 320 heats the air in the heating chamber 300, and the hot air enters the roasting chamber 400 through the cyclone chamber 330. The hot air evenly heats the coffee beans in the roasting chamber 400. At the same time, the baffle 230 continues to operate to ensure that the coffee beans are heated evenly during the roasting process, avoiding local overheating that could lead to scorching or uneven roasting.

[0088] During the baking process in the baking chamber 400, the heat inside the baking chamber 400 is transferred to the outer surface of the baking chamber 400. At the same time, the heat generated by the power control module 500 and the airflow chamber 100 is generated by the operation of the fan 310, which causes the airflow to enter from the air inlet 110 and absorb the heat generated around the baking chamber 400 and the heat generated by the power control module 500 and the airflow chamber 100 into the heating chamber 300, thus realizing heat recovery. This cycle continues.

[0089] S2, the temperature data inside the cyclone chamber 330 is monitored in real time by the temperature sensor 340, and the working status of the fan 310 and heater 320 is adjusted by the power control module 500 according to the temperature data; specifically, the temperature sensor 340 monitors the temperature change inside the cyclone chamber 330 in real time and feeds the data back to the power control module 500, so as to achieve precise control of the baking temperature by intelligently adjusting the working status of the fan 310 and heater 320.

[0090] S3, When the coffee beans reach the preset roasting level, the power control module 500 controls the fan 310 to increase its speed so that the coffee beans and hot air in the roasting chamber 400 enter the airflow channel 200 and are transported to the cyclone filter 450 for separation to complete the roasting.

[0091] Specifically, when the coffee beans reach the preset roasting level, the power control module 500 increases the speed of the fan 310, causing the coffee beans and hot air in the roasting chamber 400 to enter the airflow channel 200 and be transported through the airflow channel 200 to the cyclone filter 450 for separation. After being separated by the cyclone filter 450, the coffee beans fall into the material collection bin 410, while the hot air is discharged through the air outlet 210. After the coffee beans have been completely transferred to the material collection bin 410, the fan 310 and the heater 320 are turned off, completing the roasting process.

[0092] In this embodiment, when the coffee beans reach a preset roasting level, the power control module 500 controls the fan 310 to increase its speed, so that the coffee beans and hot air in the roasting chamber 400 enter the airflow channel 200 and are transported through the airflow channel 200 to the cyclone filter 450 for separation, completing the roasting process, including:

[0093] When coffee beans are roasted in the roasting room 400, the power control module 500 sends a smoke extraction fan start command to the communication control module to control the smoke extraction fan in the smoke extractor to absorb the hot air or smoke discharged from the air outlet 210. The communication control module is wirelessly connected to the power control module 500.

[0094] When the temperature sensor 340 in the roasting chamber 400 detects that the coffee bean temperature is about to reach the state of producing smoke, the power control module 500 sends a smoke heater start command to the communication control module to control the smoke heater in the smoke remover to heat the smoke to achieve the conditions for catalyst oxidation.

[0095] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the technical solutions of the present invention have been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
