Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] Example 1 like Figures 1-5 As 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.

[0020] 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.

[0021] The air flow chamber 100 is provided with a heating chamber 300 communicating with the air flow chamber 100. In the embodiment, the heating chamber 300 is vertically arranged in the transverse air flow cavity 101. The heating chamber 300 is provided with a fan 310. The fan 310 is provided with a heater 320. The heater 320 is provided with a cyclone bin 330. The cyclone bin 330 is provided with a temperature sensor 340. The temperature sensor 340 is used to monitor the temperature change inside the cyclone bin 330 in real time. Thus, through the operation of the fan 310, the heat in the air flow chamber 100 can be negatively pressured into the heating chamber 300. At the same time, the heater 320 is used for heating and generating hot air. The generated hot air enters the cyclone bin 330. In turn, the heat in the air flow chamber 100 can be negatively pressured into the heating chamber 300 to achieve heat recovery. In addition, the hot air in the cyclone bin 330 can be fed back to the power control module 500 (which will be described in detail below) after being monitored by the temperature sensor 340. Thus, the working state of the heater 320 can be adjusted according to the actual temperature requirement to realize precise temperature control.

[0022] The air flow chamber 100 is also provided with a power control module 500. In the embodiment, the power control module 500 is arranged in the longitudinal air flow cavity 102 and arranged side by side with the heating chamber 300. The power control module 500 is electrically connected with 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, so as to realize closed-loop control of the hot air temperature.

[0023] In the embodiment, the heat generated by the power control module 500 can be negatively pressured into the heating chamber 300 by the operation of the fan 310 to realize heat energy recovery in the air flow chamber 100.

[0024] The heating chamber 300 is communicated with a baking chamber 400. The top of the baking chamber 400 is communicated with the first end of the air flow channel 200. The second end of the air flow channel 200 is communicated with a cyclone filter 450. An air outlet 210 is arranged on the second end of the air flow channel 200. One end of the air outlet 210 is exposed at the top of the cyclone filter 450. The bottom of the cyclone filter 450 is provided with a material collecting barrel 410.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] In this embodiment, the turbulence hammer 230 is detachably installed inside the feed hopper 220.

[0029] In one embodiment, a feed channel exists between the feed hopper 220 and the turbulence hammer 230.

[0030] In one embodiment, the turbulence hammer 230 is capable of covering and sealing the feed hopper 220.

[0031] 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. When the coffee beans reach the preset roasting degree, the power control module 500 increases the speed of the fan 310 to make the coffee beans in the roasting chamber 400 and the hot air enter the first annular bin 201 and then enter the second annular bin 202 through the connecting channel 203, and then are transported to the cyclone filter 450 for separation. The cyclone filter 450 uses the centrifugal force generated by the high-speed airflow to efficiently separate the coffee beans from the hot air, avoiding the clogging problem caused by the traditional screen filter, and improving the separation efficiency. The separated coffee beans directly fall into the material collection barrel 410 through the bottom of the cyclone filter 450, and the collection is completed; and the hot air is discharged through the air outlet 210, thereby realizing the roasting of the coffee beans.

[0032] In this embodiment, the air outlet 210 is connected with a smoke extractor, which includes a smoke suction fan, a smoke heater, a smoke sensor and a catalyst; so that the hot air and smoke enter the smoke extractor through the air outlet 210 for smoke removal.

[0033] In this embodiment, the shell is also included, and the airflow chamber 100, the airflow channel 200, the heating chamber 300, the roasting chamber 400 and the cyclone filter 450 are all arranged inside the shell, forming a roasting device with compact structure and integrated functions.

[0034] In this embodiment, the bottom of the shell is provided with support feet, which are uniformly distributed around the bottom of the shell, ensuring the stability and balance of the whole device; at the same time, the bottom of the support feet is provided with anti-skid pads to reduce vibration and noise during operation of the device and prevent the device from sliding to cause safety hazards; the height of the support feet is adjustable to adapt to different ground conditions and ensure that the device is in a horizontal state, thereby ensuring the normal operation of the internal components.

[0035] In this embodiment, the shell is provided with a control panel connected with the power control module 500 for setting and monitoring the roasting parameters; the key parameters such as roasting temperature, time and speed of the fan 310 can be set through the control panel, and the current operating state and temperature curve are displayed in real time, which facilitates the operator to accurately master the roasting process. In addition, the control panel also has a self-checking function, which automatically prompts alarm information when the device is abnormal, ensuring the stable operation of the device. The whole roasting process has high automation degree and is easy to operate, which is suitable for personalized roasting needs of different types of coffee beans, greatly improving the production efficiency and consistency of product quality. Further, in order to enhance the applicability and stability of the device.

[0036] The airflow chamber 100 is provided with an air inlet 110 on the side facing the roasting chamber 400, and the fan 310 is used to pass the external air from the air inlet 110, the heating chamber 300, the roasting chamber 400 and the airflow channel 200 in sequence; at the same time, the setting of the air inlet 110 can also adsorb the heat on the outer surface of the roasting chamber 400, so that the outer surface of the roasting chamber 400 can also be cooled and the heat can be recycled.

[0037] In the embodiment, the air inlet 110 is arranged on the side of the longitudinal air flow cavity 102 facing the baking chamber 400; the air inlet 110 is arranged to enable external air to smoothly enter the air flow chamber 100, thereby providing a continuous source of fresh air for the air flow circulation system, ensuring the stability and flowability of the air flow during the baking process, and avoiding the occurrence of temperature fluctuations or local heat accumulation due to poor air flow.

[0038] In the embodiment, a filtering device is arranged at the air inlet 110 to remove impurities and dust that may be carried in the air, thereby ensuring the cleanliness of the air flow entering the baking chamber 400 and avoiding secondary pollution of the coffee beans.

[0039] In the embodiment, the air flow chamber 100 is further provided with an illuminating lamp 550, the illuminating lamp 550 is connected with the power supply control module 500, and the illuminating lamp 550 is located on one side of the air inlet 110, so that the baking chamber 400 can be illuminated through the air inlet 110.

[0040] In the embodiment, the baking chamber 400 is a transparent glass baking chamber; therefore, the arrangement of the illuminating lamp 550 not only improves the visibility of the equipment, making it convenient for the operator to observe the baking state and color change of the coffee beans, but also helps to adjust the baking parameters in a timely manner, ensuring that the coffee beans achieve the desired baking effect. The combination of the visual operation interface and real-time illumination further improves the human-machine interaction experience of the equipment, making the entire baking process more intuitive, controllable, and enhancing the precision and convenience of the operation.

[0041] Because the transparent glass window on the baking machine is easily contaminated by smoke and oil stains generated during baking after being used for a period of time, disassembling and cleaning the glass window requires disassembling the machine, and the process is complex.

[0042] In the embodiment, the baking chamber 400 is detachably connected with the air flow chamber 100 and the air flow passage 200 through the dismounting mechanism; thereby, it is convenient for the operator to regularly clean or replace the transparent glass window, avoiding the influence of smoke residue and oil stains accumulation on the observation effect As 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] Example 2 The difference between this embodiment and Embodiment 1 is that: 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.

[0055] In this embodiment, the receiving cavity is an open receiving cavity, so that the receiving cavity can communicate with the outside.

[0056] 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.

[0057] Example 3 like Figure 13 As shown, a method for controlling a coffee roaster includes the following coffee bean roasting process steps; 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. 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. During the roasting process of the roasting chamber 400, heat in the roasting chamber 400 is transferred to the outer surface of the roasting chamber 400, and the heat generated by the power control module 500 and the airflow chamber 100 is absorbed by the airflow from the air inlet 110 into the heating chamber 300 through the operation of the fan 310, realizing the recycling of heat, and thus the circulation is realized. S2, the temperature data in the cyclone bin 330 is monitored in real time by the temperature sensor 340, and the working state of the fan 310 and the heater 320 is adjusted by the power control module 500 according to the temperature data; specifically, the temperature sensor 340 monitors the temperature change in the cyclone bin 330 in real time, and feeds back the data to the power control module 500, and adjusts the working state of the fan 310 and the heater 320 intelligently, realizing accurate control of the roasting temperature; S3, when the coffee beans reach the preset roasting degree, the fan 310 is controlled by the power control module 500 to increase the 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 through the airflow channel 200 for separation, and the roasting is completed. Specifically, when the coffee beans reach the preset roasting degree, the power control module 500 increases the speed of the fan 310 to make the coffee beans and hot air in the roasting chamber 400 enter the airflow channel 200 and be transported to the cyclone filter 450 through the airflow channel 200 for separation, and the coffee beans are separated by the cyclone filter 450 and fall into the material collecting barrel 410, while the hot air is discharged through the air outlet 210; after the coffee beans are completely transferred to the material collecting barrel 410, the fan 310 and the heater 320 are turned off, and the roasting process is completed.

[0058] In this embodiment, when the coffee beans reach the preset roasting degree, the fan 310 is controlled by the power control module 500 to increase the 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 through the airflow channel 200 for separation, and the roasting is completed, including: When the roasting chamber 400 roasts the coffee beans, the power control module 500 sends a smoke suction fan starting instruction to the communication control module to control the smoke suction fan in the smoke removal machine to absorb the hot gas or smoke discharged from the air outlet 210, wherein the communication control module is wirelessly connected with the power control module 500; When the temperature sensor 340 in the roasting chamber 400 detects that the temperature of the coffee beans is about to reach the state of generating smoke, the power control module 500 sends a smoke heater starting instruction to the communication control module to control the smoke heater in the smoke removal machine to heat the smoke, so that the smoke heating reaches the catalyst oxidation condition.
