[0031] The staff first removes the drum 5, places the tea leaves to be roasted, installs the drum 5 through the connecting piece 4, opens the discharge plate 12, and uses a tool to pull out the movable plate 13 to add and replace the charcoal. Then, the movable plate 13 is reset and the discharge plate 12 is closed. The hot air caused by the heating of the charcoal will pass through the small circulation space between the No. 1 arc-shaped groove 11 and the No. 2 arc-shaped groove 22 and flow upward. The air flow drives the heat generated by the charcoal in the combustion process to transfer upward. At the same time, under the effect of heat conduction, the ambient temperature in the furnace lining 2 gradually increases with the heating of the charcoal, thereby achieving the effect of preheating in advance and accelerating the roasting speed; then, the motor 32 and the fan 21 are started, so that the No. 2 ventilation plate 34 rotates, and then the connecting rod 35 is driven to rotate, and the furnace lining 2 rotates synchronously with the rotation of the connecting rod 35 until the positions of the No. 1 arc-shaped groove 11 and the No. 2 arc-shaped groove 22 are completely corresponding, and the motor 32 stops working;
[0032] Under the action of the fan 21, the heat is transferred to the maximum extent, so that the temperature inside the drum 5 rises rapidly. (Here, the bottom area of the cavity of the connecting frame 3 is set to be equal to the area of the first ventilation plate 31 to avoid a large amount of airflow escaping from the cavity of the connecting frame 3 due to the excessive bottom area of the cavity of the connecting frame 3, thereby causing the loss of hot air.) A temperature sensor is fixedly connected to the connecting frame 3 near the drum 5. When the temperature set by the temperature sensor reaches a certain threshold (60°C for most tea leaves), the temperature sensor transmits an electrical signal to the controller. At this time, the controller controls The motor 32 is controlled to rotate in the opposite direction, so that the circulation space between the first through groove 311 and the second through groove 341 becomes smaller, and the circulation space between the first arc-shaped through groove 11 and the second arc-shaped through groove 22 also becomes smaller, so that the continuously rising reading of the temperature sensor becomes slower, and the rotation of the motor 32 is controlled by the reading of the temperature sensor, thereby controlling the circulation space changes between the first through groove 311 and the second through groove 341, and between the first arc-shaped through groove 11 and the second arc-shaped through groove 22, controlling the temperature of the tea leaves in the drum 5, and improving the controllability of the temperature during the carbon baking process;
[0033] When the temperature sensor reading is almost no longer rising, the temperature sensor transmits an electrical signal to the controller again, and the controller stops the control of the motor 32, so that the temperature of the tea leaves is kept within a certain range. The temperature is adaptively adjusted by the temperature sensor, which saves the time of human supervision and reduces the labor intensity. When the specified time is reached, the fan 21 is turned off and the motor 32 is started again, so that the No. 1 through groove 311 and the No. 2 through groove 341 are misaligned, and the No. 1 arc through groove 11 and the No. 2 arc through groove 22 are also misaligned. At this time, the charcoal is in a state of burning for a period of time without oxygen supply, and the charcoal fire gradually goes out. After the charcoal fire is extinguished, the motor is started 32, so that the first arc groove 11 and the second arc groove 22 form a small circulation space, at this time, the fan 21 is turned on, the outside air is sucked into the furnace lining 2, and circulated from the cavity of the connecting frame 3 and the furnace body 1, so that the tea leaves are cooled, and the leaf temperature is reduced while the dry tea leaves absorb the outside moisture and redistribute it, so as to avoid the tea leaves being too dry to be completely taken out and packaged; after the work is completed, the fan 21 is stopped, and the charcoal fire and the cooled tea leaves are taken out; in this process, different thresholds of the temperature sensor can be set for different tea leaves, so that the present invention can be applied to the baking of multiple types of tea leaves, and the baking temperature can be flexibly controlled.
[0034] As a specific embodiment of the present invention, the connecting frame 3 is fixedly connected with a cylinder 52 that wraps the drum 5, and the cylinder 52 is divided into a lower cylinder 521 fixedly connected to the connecting frame 3 and an upper cylinder 522 hinged to the lower cylinder 521. The upper cylinder 522 and the lower cylinder 521 form a flip cover structure at the hinge, which is convenient for installing and removing the drum 5. A through hole is opened on the side of the lower cylinder 521. The cylinder 52 can block external debris and dust during the tea baking process. At the same time, the bottom of the cylinder 52 can collect the defective and small tea leaves inside the drum 5, which is convenient for classifying tea leaves of different sizes, thereby improving the overall quality of the tea leaves, and at the same time improving the recovery rate of the tea leaves after baking.
[0035] As a specific embodiment of the present invention, a HEPA filter 6 is fixedly connected to the bottom of the fan 21 in the furnace lining 2 to prevent impurities generated by charcoal combustion from entering the tea leaves under the action of the fan 21 and causing pollution to the tea leaves. On the other hand, after some charcoal impurities adhere to the HEPA filter 6, they fall back onto the movable plate 13 under the influence of their own weight when the fan 21 is turned off, thereby reducing the pollution to the environment caused by dust escape during charcoal combustion.
[0036] As a specific embodiment of the present invention, a gas distributor 7 is fixedly connected to the bottom of the cylinder 52 of the connecting frame 3, so that the wind blown out from the No. 1 through groove 311 is evenly distributed and blown toward the cylinder 52, so that the tea leaves are evenly heated during the baking process.
[0037] As a specific embodiment of the present invention, the connecting member 4 includes a fixed shaft 41, a buckle 42 and a buckle slot 43 (the overall shape of the buckle 42 and the buckle slot 43 here can be the Mohabi buckle 42 on the backpack in the prior art), the fixed shaft 41 passes through the connecting frame 3 and is located inside the cylinder 52, the buckle 42 is fixed to the end of the fixed shaft 41 away from the connecting frame 3, the buckle slot 43 is fixed to both sides of the drum 5, the buckle 42 and the buckle slot 43 are mutually locked, and a wind wheel 36 is installed at the cavity of the connecting frame 3 and the furnace body 1, and the wind wheel 36 is fixed to the end of the fixed shaft 41 away from the buckle 42;
[0038] During the installation of the drum 5, the staff adjusts the direction of the fixed shaft 41 so that the buckle 42 faces upward, and directly presses the buckle grooves 43 on both sides of the drum 5 toward the buckle 42, so that the buckle 42 is stuck in the buckle groove 43, thereby fixing the drum 5; when the fan 21 is started, part of the wind in the fan 21 will be dispersed to the cavity between the connecting frame 3 and the furnace body 1, and then escape to the outside, and in this process, the wind wheel 36 will be driven to rotate, and then the fixed shaft 41 rotates with the wind wheel 36, and the buckle 42 will also rotate, so that the drum 5 is continuously rotated during the baking process, so that the tea leaves in the drum 5 are constantly rolling, so that the tea leaves are evenly heated;
[0039] During the cooling process, the drum 5 is still rotating driven by the wind wheel 36, so that the heat is evenly dissipated during the tumbling of the tea leaves, and the cooling speed is increased at the same time.
[0040] As a specific embodiment of the present invention, the bottom of the connecting frame 3 is an arc-shaped structure, so that the wind blown by the fan 21 flows more smoothly into the cavity between the connecting frame 3 and the furnace body 1, reducing resistance.
[0041] As a specific embodiment of the present invention, a flap 51 is hinged on one side of the drum 5 through a movable hinge, and the side socket slot 43 is divided into two parts, one of which is fixed to the flap 51. After the buckle 42 is engaged with the buckle slot 43, the flap 51 is fixed and cannot be folded, so that the tea leaves in the drum 5 will not leak out due to the shaking of the flap 51; after the flap 51 is opened, the staff can place the required roasted tea leaves. The drum 5 is made of bamboo. Compared with metal materials, the drum 5 made of bamboo can reduce the damage to the tea leaves when colliding with the tea leaves when rolling. On the other hand, the charcoal and bamboo allow the tea leaves to absorb the fragrance of fire and bamboo during the baking process, thereby improving the taste of the tea leaves.
[0042] As a specific embodiment of the present invention, a baffle 8 is provided on the top of the cavity between the connecting frame 3 and the furnace body 1. The baffle 8 and the furnace body 1 are hinged by a movable hinge to prevent foreign matter from entering the interior of the furnace body 1 from the top of the cavity between the connecting frame 3 and the furnace body 1. An air outlet 81 is provided on the surface of the baffle 8 so that the gas of the fan 21 can flow through the air outlet 81. The air outlet 81 limits the flow direction of the airflow, thereby ensuring that the wind wheel 36 can work normally.
[0043] Working principle:
[0044] The staff first removes the drum 5, opens the flap 51 and places the tea leaves to be roasted in the drum, then closes the flap 51, and installs the drum 5 through the connector 4. During the installation of the drum 5, the staff adjusts the direction of the fixed shaft 41 so that the buckle 42 faces upward, and presses the buckle grooves 43 on both sides of the drum 5 directly toward the buckle 42, so that the buckle 42 is stuck in the buckle groove 43, thereby fixing the drum 5; opens the discharge plate 12, and uses a tool to pull out the movable plate 13 to add and replace the charcoal, then resets the movable plate 13, and then closes the discharge plate. The first arc groove 11 and the second arc groove 22 are connected to each other, and the small circulation space between the first arc groove 11 and the second arc groove 22 drives the heat generated by the charcoal in the combustion process to transfer upward; then the motor 32 and the fan 21 are started, so that the second ventilation plate 34 rotates, and then the connecting rod 35 is driven to rotate, and the furnace lining 2 also rotates synchronously, so that the first arc groove 11 and the second arc groove 22 are completely corresponding, and the first groove 311 and the second groove 341 are completely corresponding, and the motor 32 stops working. When the temperature set by the temperature sensor reaches a certain threshold, the temperature sensor transmits the electric The signal is sent to the controller, and the controller controls the motor 32 to rotate in the opposite direction, so that the circulation space between the No. 1 through groove 311 and the No. 2 through groove 341 becomes smaller, and the circulation space between the No. 1 arc-shaped through groove 11 and the No. 2 arc-shaped through groove 22 also becomes smaller, so that the rising reading of the temperature sensor becomes slower; and when the reading of the temperature sensor no longer rises, the temperature sensor transmits an electrical signal to the controller again, and the controller stops the control of the motor 32, so that the tea baking temperature is kept within a certain range. When the specified time is reached, the fan 21 is turned off and the motor is started again. 32, so that the first through groove 311 and the second through groove 341 are misaligned, and the first arc-shaped through groove 11 and the second arc-shaped through groove 22 are also misaligned. At this time, the charcoal is in a state of burning for a period of time without oxygen supply, and the charcoal fire gradually goes out. After the charcoal fire is extinguished, the motor 32 is started, so that the first arc-shaped through groove 11 and the second arc-shaped through groove 22 form a small circulation space. At this time, the fan 21 is turned on, and the outside air is sucked into the furnace lining 2, and circulated from the cavity between the connecting frame 3 and the furnace body 1, so that the tea leaves are cooled; after the work is completed, the fan 21 is stopped, and the charcoal fire and the cooled tea leaves are taken out.
