Method for improving quality of cut tobacco in recovered silver cut stems and treatment system

Abstract

The invention relates to a method for improving quality of cut tobacco in recovered silver cut stems and a treatment system and belongs to the technical field of tobacco processing. Firstly, the silver cut stems are subjected to moisture regain treatment with a normal-temperature moisture regain process and then sieved and loosened with a special-shaped sieve, then, cut stems and cut tobacco are separated through air separation equipment, finally, the recovered cut tobacco is dried with a normal-temperature drying process. The separation accuracy and effect of the cut stems and the cut tobaccoare improved, the sensory quality of the recovered cut tobacco is not affected by thermal processing treatment, the application range of the recovered cut tobacco is enlarged, and the economic valueof the recovered cut tobacco is increased.

Description

technical field [0001] The invention belongs to the technical field of tobacco processing, and in particular relates to a method for improving the quality of recycled shredded tobacco. Background technique [0002] At present, the stem sticks removed from the cigarette machine contain a large amount of shredded tobacco that has been rejected by mistake. Compared with shredded tobacco, small stem sticks have a smaller air suspension speed difference, so the separation effect is not ideal. Most of the separated shredded tobacco is a mixture of shredded shreds and shredded stems. The long filaments and long stems are separated together due to their weight. , so the utilization rate of the separated shredded tobacco is low. [0003] Chinese patent 200410041317.6 provides a method for removing stems from shredded tobacco. It is to air-separate the shredded tobacco at the outlet of the shred dryer, and comb the agglomerated shreds loosely before performing the second aeration. T...

[0002] At present, the stem sticks removed from the cigarette machine contain a large amount of shredded tobacco that has been rejected by mistake. Compared with shredded tobacco, small stem sticks have a smaller air suspension speed difference, so the separation effect is not ideal. Most of the separated shredded tobacco is a mixture of shredded shreds and shredded stems. The long filaments and long stems are separated together due to their weight. , so the utilization rate of the separated cut tobacco is low

[0003] Chinese patent 200410041317.6 provides a method for removing stems from shredded tobacco. It is to air-separate the shredded tobacco at the outlet of the shred dryer, and comb the agglomerated shreds loosely before performing the second aeration. There are essential differences in shredded shredded tobacco. The shredded tobacco exported by the shred drying machine accounts for more cut tobacco and less stem shreds, while the recycled stem shreds have more stem shreds and less tobacco shreds; If the stems are removed, the accuracy of the air separation will decrease sharply under high flow rate, and even the shredded tobacco cannot be separated

[0004] Chinese patent CN201010120362.6 provides a process for separating and recycling shredded tobacco from a cigarette machine, which uses the existing shred processing equipment to recycle the shredded stems removed from the cigarette machine, and rehydrates, expands, dries, and airs through the shred drying machine. Realize the separation of stem sticks and shredded tobacco; however, the thermal processing of shredded stems and shredded tobacco can easily damage the sensory quality of shredded tobacco, so that the shredded tobacco after separation can only be downgraded for use, reducing the economic benefits of shredded tobacco
