Problems solved by technology
These two methods both use the drum type moisture regainer for moisture regain. Their disadvantages are: the crushing is relatively large. In the process of being hit by rake nails and in the process of falling, it is easy to form fragments, and the tobacco leaves are relatively fragmented
Moreover, the processing time is long (6min), and the discharge of tailings is not complete (8-10min for complete discharge) and discontinuous. It takes a total of 10-15min for a single brand from the end of feeding to complete discharge, which is not suitable for continuous and rapid replacement of production brands.

Embodiment Construction
[0012] The specific implementation manners and related technical problems of the present invention will be further described in detail below in conjunction with the accompanying drawings. The method of the present invention is a brand new method, and the device of the present invention is a brand new device. For the sake of brevity, the method and the device are combined for description. The most important point of the present invention is to change the method of flipping the tobacco leaves up and down in the drum dampening machine in the prior art, and replace the drum dampening machine of the prior art with the dampening machine of the present invention. After the tobacco leaves are heated and loosened by microwaves, It is transported by mesh belt, sprayed with atomized hot water (or called hot steam and water), to form a humid heat environment of 50-70°C in the moisture resurfacing chamber, and the tobacco leaves are kept in this humid heat environment for 3 to 4 minutes, ab...

The invention discloses a method for loosening and remoistening tobacco leaves and equipment thereof, which belong to the technical field of cigarettes. The method is characterized in that the loosened tobacco leaves which are heated by microwave are remoistened on a mesh-belt convey belt in a damping machine; a moist heat environment at a temperature of between 50 and 70 DEG C is formed in a nozzle atomizer in the damping machine; and the tobacco leaves are kept in the moist heat environment for 3 to 4 minutes so as to be remoistened by absorbing moist heat. A feeding belt of the equipment for loosening and remoistening the tobacco leaves is connected between a microwave chamber and a refiner, wherein the discharging end of the refiner is connected with the feeding end of the damping machine; at least one mesh-belt convey belt is arranged in the damping machine; a plurality of nozzles which spray atomized hot water are arranged in the damping machine; and the discharging end of the mesh-belt convey belt is arranged above a discharge chute. The method of the invention has low resurgence temperature, low degree of fragmentation and can improve the processing intensity resistance of the tobacco leaves. The equipment has reasonable design and easy implementation, can ensure the remoistening quality of the tobacco leaves, has fast processing speed, and can meet the requirement of changing varieties in production in time.
Description
technical field [0001] The invention belongs to the technical field of cigarettes, and in particular relates to a new method for rehydrating tobacco leaves in a loose state and special equipment for the method. Background technique [0002] In the prior art, there are two methods for tobacco leaf rehydration, one is: feeding-slicing-drum tobacco leaf rehydration-subsequent process; the other is: feeding-microwave loosening-drum tobacco leaf rehydration-subsequent process. These two methods both use the drum type moisture regainer for moisture regain. Their disadvantages are: the crushing is relatively large. In the process of being hit by rake nails and in the process of falling, it is easy to form broken pieces, and the broken pieces of tobacco leaves are relatively large. Tobacco leaves are treated more intensively in the drum-type tobacco leaf moistening machine (the temperature of the hot air on the drum is about 130°C), so that the loosening effect can be achieved, and...
