[0002] Carbonized moxa sticks are moxa sticks that have been carbonized. They produce less smoke and odor when burned, and are suitable for people who are sensitive to smoke. Carbonized moxa sticks require carbonized moxa leaves. The method of making carbonized moxa leaves is to put the moxa leaves into a wok and fry them over high heat until they turn black, then put them into a sealed barrel and seal them for 24 hours before crushing them.

[0003] At present, the method of frying mugwort leaves is: pour the mugwort leaves into a wok, heat the wok with high heat, and stir-fry the mugwort leaves with a spatula.

[0043] The implementation principle of the wormwood carbonization device with recycling volatile gas of wormwood leaves in the embodiment of the present application is as follows: when in use, first start the electric boiler 26, close the regulating valve 27, the electric boiler 26 heats the oil and then sends it into the hot oil tank 1 through the oil filling pipe 4, the hot oil falls on the blades 3, and drives the drum 2 to rotate. At the same time, the liquid level height on the side close to the oil filling pipe 4 in the hot oil tank 1 is greater than the other side, so under the action of potential energy, the hot oil flows to the side close to the return oil pipe 5 in the hot oil tank 1, which also drives the drum 2 to rotate. After the hot oil in the hot oil tank 1 reaches a certain temperature, Open the end cover 9 and put the mugwort leaves into the drum 2 through the connecting hole 208. After the feeding is completed, plug the end cover 9 into the end of the connecting hole 208; then, open the regulating valve 27, the liquid level on the side of the hot oil tank 1 close to the return oil pipe 5 is reduced, and the height difference of the liquid levels on both sides of the hot oil tank 1 increases. The hot oil flows to the side of the hot oil tank 1 close to the return oil pipe 5, pushing the drum 2 to rotate, and the mugwort leaves are stir-fried in the drum 2. The fan 16 is started during the stir-frying process; finally, after the mugwort leaves are fried, remove the end cover 9 and use the negative pressure extraction device to extract the mugwort leaves from the drum 2.

[0044] The wormwood carbonization device with the function of recovering the volatile gas of the wormwood leaves in the embodiment of the present application has at least the following beneficial effects:

[0045] First, the production safety is greatly improved. The hot oil is used for frying, which avoids the use of open flames and improves the safety of production. At the same time, during the frying of mugwort leaves, the end cover 9 seals the space in the drum 2. Since the oxygen content is prioritized, the burning of mugwort leaves during frying can be greatly reduced. At the same time, the frying of mugwort leaves is completed in the drum 2, so the problem of sparks generated during the frying of mugwort leaves flying out and causing fire can be avoided.

[0046] Second, it saves energy and reduces emissions, and reduces work intensity. The solution of the present application uses the drum 2 to stir-fry the mugwort leaves, which greatly reduces the labor intensity. At the same time, the turning of the drum 2 is driven by the liquid level difference of the injected hot oil, which reduces the use of motor equipment, reduces the manufacturing cost of the equipment, and at the same time, reduces the power consumption during use.

[0047] Third, the collection of volatile liquid of mugwort leaves is realized; during the process of frying the mugwort leaves under heat, some of the medicinal components in the mugwort leaves are volatilized, and the present application collects them in the collection box 15 by condensation and liquefaction;

[0048] Fourthly, the rotation of the drum 2 drives the spiral guide vane 24 to rotate, and the rotation of the spiral guide vane 24 can facilitate the gas in the drum 2 to be sent into the gas outlet pipe 11. Of course, in order to further increase the circulation speed, a fan 16 is set in the gas return pipe 12;

[0049] Fifthly, the brush 10 is provided on the blade 3 of the present application, which has at least the following beneficial effects: firstly, the gap between the blade 3 and the bottom of the hot oil tank 1 is greatly reduced, which is conducive to fully using the liquid level difference to drive the drum 2 to rotate; secondly, when the drum 2 rotates and drives the brush 10 to leave the hot oil, the next section of the side wall of the drum 2 does not contact the hot oil, and the brush 10 has more hot oil due to the capillary action, and the hot oil flows back to the side wall of the drum 2 under the action of its own weight, thereby achieving a certain degree of heat preservation; finally, due to the provision of the brush 10, when the blade 3 moves to the bottom of the oil filling pipe 4, the blade 3 can carry more hot oil, which is more conducive to driving the drum 2 to rotate;

[0050] Sixth, the blades 3 in the present application are not only used to drive the drum 2 to rotate, but also increase the contact area between the side wall of the drum 2 and the hot oil, which is more conducive to the temperature of the hot oil being transferred to the drum 2;

[0051] Seventh, in the present application, the air in the drum 2 is cooled by the cooling box 14 and sent to the connecting hole 208, which is conducive to reducing the temperature in the connecting hole 208 and facilitating the delivery of wormwood leaves into the drum 2 through the connecting hole 208;

[0052] Eighth, the rotation speed of the drum 2 is controlled by the regulating valve 27; when it is necessary to accelerate the rotation of the drum 2, the opening amplitude of the regulating valve 27 is increased, the oil return speed is increased, the liquid level difference on both sides of the drum 2 in the hot oil tank 1 is increased, and the rotation of the drum 2 is accelerated; when it is necessary to reduce the rotation speed of the drum 2, the opening amplitude of the regulating valve 27 is reduced, the liquid level difference on both sides of the drum 2 in the hot oil tank 1 is reduced, and the rotation speed of the drum 2 is reduced.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
