Cross-flow type cylinder tobacco dryer

Abstract

The invention provides a cross flow type roller tobacco dryer, which comprises a roller, a hot air inlet pipeline system, a moisture discharging pipeline system, a feed opening and a discharge opening. The tobacco dryer is characterized in that a hot air pipe is inserted from the lower part of the feed opening of the roller; an air inlet of the hot air pipe is arranged on the eight-o'clock position(on the side opposite to the lifted cut tobacco) in the roller, and the width of the air inlet is the same as the length of the roller; the radial air inlet is realized along the direction of the opening face of the air inlet facing to the shaft line of the roller, and air inlet grid plates are arranged along the whole air inlet; a moisture discharging port is arranged on the twelve-o'clock position, the opening of the moisture discharging port is downward, and the width of the moisture discharging port is the same as the length of the roller; and a filter net and air outlet grid plates are arranged along the whole moisture discharging port, and a moisture discharging pipe extends out of the upper part of the feed opening. The tobacco dryer is characterized in that due to the reasonable arrangement of the hot air inlet and the moisture discharging port, the problem of uneven treatment strength along the axial direction and the influence of air speed on the staying time are eliminated. According to style characteristics of products, a control method can be freely chosen, thereby reducing the risk of structural fluctuation of the cut tobacco and stabilizing the physical indexes of the products.

Description

technical field [0001] The invention belongs to tobacco processing equipment, in particular to a cross-flow drum shred drying machine on a cigarette shred line. Background technique [0002] Shredded leaf drying is an important process in the cigarette processing process. The technological task of this process is to remove part of the moisture in the shredded tobacco, make the shredded tobacco dry and shape, increase the curl and elasticity, improve the filling capacity and processing resistance of the shredded tobacco, and improve and improve the shredded tobacco. The sensory quality makes the overall quality of shredded tobacco reach a more coordinated state, and meets the processing requirements of the post-process. Drum drying machine is one of the main equipment to realize this process. It is a drying process under the composite drying method. The main heat transfer methods are contact conduction and forced convection (hot air). Effective contact to achieve heat and ma...

Problems solved by technology

[0007] This invention is a new type of cross-flow drum silk drying machine designed for the problems existing in the current downstream or counter-current drum silk drying machines. By reasonably setting the hot air inlet and the moisture discharge outlet, the uneven treatment intensity along the axis can be eliminated. problem, eliminating the effect of wind speed on dwell time
