Abstract

The invention provides a flash evaporation puffing and roller drying treatment process for stalk shreds. According to the treatment process, jet type stalk shred heating and humidifying equipment and steam-heated drum-type shred baking equipment are adopted, the filling value of the stalk shreds is increased from 5.6 cm<3> / g to 6.0 cm<3> / g, namely increased by 7.1%, the processing resistance of the stalk shreds is markedly increased, the stalk shred output rate is increased by 0.6%, the integral stalk shred rate is increased by 1.4%, the outlet water content of the dried stalk shreds is uniform, the water content fluctuation is controlled within a range of + / -0.4%, the woody gas influence caused by stalk shreds in the cigarette product is effectively avoided, and at the same time, the dried stalk shreds are better in water content uniformity and lower in water content fluctuation.

Description

technical field [0001] The invention belongs to the cigarette production technology, in particular to a shredded stem flash puffing and drum drying treatment technology. Background technique [0002] At present, there are mainly the following methods for puffing and drying cut stems. The first method is cut stems HT + cut stems roller (or fluidized bed) drying method; the second method is cut stems flash puffing + cut stems fluidized bed drying method. The first method is the conventional cut stem processing method, which has mature processing technology and is widely used. Relatively speaking, the HT section has a limited effect on the puffing of cut stems, and has great limitations in removing lignin gas and improving the filling capacity of cut stems. The second method is a new process mode. Compared with the first method, on the basis of the first method, the physical performance indicators of cut stems (such as filling value, cut stem structure) and performance in cigar...
