The required charcoal is put into the charcoal combustion barrel 4 to ignite the charcoal, the charcoal combustion barrel 4 with the ignited charcoal and the movable support 42 are moved into the combustion chamber 2 on the case 1 together, the first door plate 11 is closed, the baking temperature is preset on the controller 10, then the machine is started to work, the controller 10 automatically controls the working state of the control valve 7 and the air inlet valve 8, and the fan 5 is started to work; referring further to fig. 6, the fan 5 sucks the hot gas containing carbon from the combustion chamber 2 through the hot gas outlet 21 and the gas transmission channel 14 and discharges the hot gas into the gas feeding channel 31 at one side of the roasting chamber 3, the hot gas containing carbon enters the roasting chamber from the gas inlet 311 and the plurality of gas inlet through holes 312 at one side of the roasting chamber 3 to roast the material to be roasted, a part of moisture generated by roasting is discharged from the gas outlet 33 at the top of the roasting chamber 3, a part of the hot gas not subjected to heat exchange and another small part of the moisture generated by heat exchange enter the gas return channel 32 from the gas return port 321 and the plurality of gas return through holes 322 at the other side of the roasting chamber 3, and the hot gas and the moisture containing carbon in the gas return channel 32 are sucked by the fan and then returned to the roasting chamber for roasting operation until the roasting operation is completed.
When the baking chamber 3 is higher than the set temperature, the control valve 7 closes the hot air outlet 21 or closes the hot air outlet 21, opens the air inlet pipe 6 to introduce external cold air, and the cold air enters the baking chamber 3 from the air conveying channel 14 and the air feeding channel 31 to be cooled.
When the temperature of the roasting chamber 3 is lower than the set temperature, the control valve 7 opens the hot gas outlet 21 or opens the hot gas outlet 21 to be larger, and closes the gas inlet pipe 6 or closes the gas inlet pipe 6 to be smaller, so that a larger amount of carbon-containing hot gas enters the roasting chamber 3 to raise the roasting temperature. When the carbon-containing hot gas is less than the set baking temperature, the controller 10 energizes the auxiliary electric heater 9 to generate enough hot gas into the baking chamber 3 to keep the interior of the baking chamber 3 within the set baking temperature. Ensuring the baking quality.
When the temperature in the roasting chamber 3 is over-high, the protection control board cuts off the power supply of the machine. So as to protect the material to be roasted and improve the safety of the machine.
In the second embodiment and fig. 9, a difference of the carbon baking machine from the first embodiment is: the baking chamber 3 is provided with a rotating frame 30, the rotating frame 30 is driven by a third motor 301 arranged on the machine case 1 to rotate, the baking tray 37 is arranged on the rotating frame 30, and the third motor 301 is also controlled by the controller 10 to work. The bottom of the rotating frame 30 is provided with a plurality of rollers 302 that move along a circular orbit.
In the baking operation of this embodiment, the rotary frame 30 drives the baking tray 37 and the material to be baked to slowly rotate in the baking chamber 3 for better heat exchange with the hot gas containing charcoal.
While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
