Online sliver separating device for high moisture content cut tobaccos and separating method of online sliver separating device

Abstract

Disclosed is an online sliver separating device for high moisture content cut tobaccos. The online sliver separating device is mainly composed of a feeding vibration tank, a cut tobacco opening device, a high frequency vibration tank, a two-stage air separator and a discharging vibration tank which are sequentially arranged along the conveying direction of the cut tobaccos. Two opening devices are arranged in a first air separating channel and a second air separating channel which are communicated with each other in the two-stage air separator. Upper pin rollers and lower pin rollers are staggered and are specifically arranged on the opening devices to drop the cut tobaccos to achieve the loosening of the cut tobaccos. A separating method of the online sliver separating device includes that the high moisture content cut tobaccos which are cut in tobacco cutting production lines pass through the cut tobacco opening devices and then are subjected to high frequency vibration by means of the high frequency vibration tank to enable the cut tobaccos to be in wide cut, thin spread and fluffy states, then the cut tobaccos enter into the opening devices in the two-stage air separator, and finally slivers in the cut tobaccos are separated out. By means of the device and the method for separating the silvers, less broken cut tobaccos are produced in the separating process, and the ratio for rejecting the slivers out of the cut tobaccos is obviously increased.

Description

technical field [0001] The invention relates to a shredded tobacco processing device and a processing method thereof, in particular to a device and a method for separating stems from shredded tobacco with high moisture content. Background technique [0002] The percentage of stems in cigarettes is an important indicator that affects the sensory inner quality and appearance quality of cigarettes. Cigarettes with stems are prone to popping when smoked, and the smoke will contain woody gas from burning stems. Form miscellaneous gas, the stem stick in the cigarette is easy to pierce the cigarette paper wrapping the shredded tobacco, and there will be air leakage during the smoking process. [0003] Usually, there are two methods for removing stems from shredded tobacco: (1) After the shredded tobacco is cooled to 40-50°C in the shredded process, air selection is carried out, such as patent CN200410041317. (2) During the cigarette rolling process of the cigarette machine, the sh...

Problems solved by technology

After the shredded tobacco is processed by the shred drying process, the shredded tobacco is in a curled shape, which is easy to wrap the stem sticks, especially after the shredded tobacco is expanded, the density difference between the shredded tobacco and the stem sticks is reduced, both of which affect the removal effect of the stem sticks by winnowing
