Problems solved by technology

However, when roasted at a higher temperature than 220°C, the tobacco stems tend to produce a scorched smell.
[0013] In addition, in the process of automatic continuous expansion of tobacco stems, it is inevitable that occasional tobacco stems will overheat or catch fire due to unstable flow or other reasons. When polytetrafluoroethylene is used as a container, toxic gases will be released due to high temperature Contaminates the stems and also burns the drum material

Embodiment 1

[0052] The method for flavoring tobacco stems based on the aroma-increasing tobacco stem microwave expansion system provided by the present invention, goes through the following steps:

[0053] A, the tobacco stems are sent into the screening machine 1, and after screening to remove impurities, they are sent to the buffer storehouse 21 of the first conveyor 2 for buffering;

[0054] B. Send the tobacco stems in the buffer bin 21 of the first conveyor 2 to the metering conveying scale 3 through the inclined conveyor belt 23, the rake roller 24, and the feeding pipe 25 at a flow rate of 500kg / h, and then meter and convey to the second The conveyor 4 absorbs impurities such as metal iron through the powerful iron remover 5;

[0055] C. The tobacco stems in step B are sent to the temperature-increasing and humidifying conveyor 8 through the air delivery pipeline 6 and the gas-solid separation and feeding device 7, and at the same time, steam is sent to the temperature-increasing a...

Embodiment 2

[0060] The method for flavoring tobacco stems based on the aroma-increasing tobacco stem microwave expansion system provided by the present invention, goes through the following steps:

[0061] A, the tobacco stems are sent into the screening machine 1, and after screening to remove impurities, they are sent to the buffer storehouse 21 of the first conveyor 2 for buffering;

[0062] B. Send the tobacco stems in the buffer bin 21 of the first conveyor 2 to the metering conveying scale 3 through the inclined conveyor belt 23, the rake roller 24, and the feeding pipe 25 at a flow rate of 2000kg / h, and then meter and convey to the second The conveyor 4 absorbs impurities such as metal iron through the powerful iron remover 5;

[0063] C. The tobacco stems in step B are sent to the temperature-increasing and humidifying conveyor 8 through the air delivery pipeline 6 and the gas-solid separation and feeding device 7, and at the same time, steam is sent to the temperature-increasing ...

Abstract

The invention relates to an aroma enhancement tobacco stem microwave expansion system and method and belongs to the technical field of tobacco processing. The system comprises, sequentially from a feeding end to a discharging end, a screening machine, a first conveyer, a measuring and conveying scale, a second conveyer, a pneumatic conveying pipe, a gas and solid separating blanking device, a heating and humidifying conveyer, a feeding cross-port blanking device, a microwave expansion device, a discharging cross-port blanking device and a third conveyer. The aroma enhancement tobacco stem microwave expansion system can effectively eliminate impurities from tobacco stems, achieves quantitative tobacco stem conveying; after being heated and humidified, the tobacco stems are conveyed into the microwave expansion device and kept at 140-220 DEG C for 2-10 min to enhance aroma, meanwhile, a ceramic tube is ventilated at a volume of 1000-2200 m3/h to eliminate green stems, wood gas and moisture from the tobacco stems and further to obtain microwave-expanded tobacco stems high in quality and rich in aroma. The aroma enhancement tobacco stem microwave expansion system is reasonable and effective, and the aroma enhancement tobacco stem microwave expansion method is thorough and can increase the mixing quantity of the tobacco stem in cigarettes, save tobacco resources and reduce the production cost.

Description

technical field [0001] The invention relates to a tobacco stem microwave expansion system and method, in particular to a tobacco stem microwave expansion system and method that can effectively improve quality and increase aroma, and belongs to the technical field of tobacco processing. Background technique [0002] Tobacco stems are thick and hard veins on tobacco leaves except for leaves, accounting for about 25-30% of the weight of tobacco leaves, and have similar components to leaves. Since the tobacco stems will produce green and woody odors when burned, it will affect the smoking quality of the final product, that is, cigarettes, so the consumption of tobacco stems in cigarette production should not be too large. A large amount of tobacco stems are discarded and wasted every year like this. How to reduce the green and woody smell of tobacco stems, give full play to the characteristics of low tar, low nicotine content and good combustibility of tobacco stems, and increa...
