摘要： A mixture of unsatisfactory fragments of tobacco ribs and shreds of tobacco leaf laminae and/or tobacco ribs which are bonded to each other and/or are clumped together and/or crimped is treated to loosen the coherent and/or clumped shreds and/or uncrimp individual shreds and to thereupon separate the fragments of ribs from the thus liberated and/or straightened shreds. The treatment involves heating the mixture with steam, thereafter cooling (if necessary) the mixture, and thereupon pneumatically separating the shreds from the fragments of tobacco ribs. The heating operation can take place simultaneously with moisturizing of the mixture and can be carried out in a rotary or vibratory conveyor.

摘要： Bales of condensed relatively dry tobacco particles are broken up by subdividing each bale into slabs which are thereupon mechanically fragmentized, heated and moisturized with steam or steam and hot water, shredded while still heated, and thereupon subjected to one or more additional treatments. The bales are subdivided into slabs by cutting them transversely of the layers of compressed tobacco particles therein, and the heating and moisturizing steps can be carried out in a drum or in a closed tunnel of a vibratory conveyor.

摘要： Fragments of tobacco ribs are puffed in an elongated tunnel which is vibrated to advance the particles from the inlet toward the outlet. The particles in the tunnel are contacted by streamlets of supersaturated or superheated steam at such temperature and pressure that the temperature of the particles is raised to between 100.5.degree. and 120.degree. C. To this end, steam is admitted at 2.5 to 25 bar absolute pressure and at a temperature of between 126.degree. and 400.degree. C. The thus heated particles of tobacco ribs are thereupon dried.

摘要： Bales or portions of bales of relatively dry compressed tobacco leaf laminae or ribs are heated microwaves, or in an to a temperature not less than 50.degree. C., and are immediately admitted into a shredding machine without previous cooling and/or breaking up. The moisture content of the shreds is raised to between 12 and 13.5% for admission into a cigarette maker, or such moisture content is raised well above the optimum value for further processing in order to increase the filling power of the shreds. The shreds are thereupon dried to reduce their moisture content to between 12 and 13.5% prior to conversion into the filler of a cigarette rod. Two or more different types of shreds can be mixed prior to admission into the cigarette maker. The rate at which the shredding machine discharges a stream of shreds is kept constant by monitoring the density of successive bales or portions of bales and by regulating the speed at which the bales or portions of bales are delivered to the shredding station in dependency on the mass of the respective bales or portions of bales.

摘要： Apparatus for puffing, drying or moisturizing tobacco has a conveyor defining an elongated channel with an inlet and an outlet for particles of tobacco. The conveyor is vibrated so that the particles advance toward the outlet, and the bottom wall of the conveyor has orifices which serve to discharge jets of hot air or steam into the channel in such orientation that the jets of admitted fluid medium are inclined to each other, to the direction of advancement of tobacco particles and/or to the vertical. The orifices receive fluid from a chamber which is provided beneath the bottom wall and is connected to a source of steam or hot air. An advantage of the apparatus is that the exchange of heat and/or moisture between tobacco particles and the fluid is highly satisfactory, as well as that substances which are propelled by jets of fluid toward the top wall of the conveyor are more or less uniformly distributed along the entire top wall so that they are less likely to gather into large cakes which could become separated from the top wall to enter the flow of tobacco particles and to advance therewith to the next processing station. The bottom wall of the conveyor can have an undulate shape with the orifices provided in the flanks of hills which alternate with the valleys of such bottom wall.

摘要： Bales or portions of bales of relatively dry compressed tobacco leaf laminae or ribs are dielectrically heated by microwaves, or in an electric high-frequency field, to a temperature not less than 50.degree. C., and are immediately admitted into a shredding machine without previous cooling and/or breaking up. The moisture content of the shreds is raised to between 12 and 13.5% for admission into a cigarette maker, or such moisture content is raised well above the optimum value for further processing in order to increase the filling power of the shreds. The shreds are thereupon dried to reduce their moisture content to between 12 and 13.5% prior to conversion into the filler of a cigarette rod. Two or more different types of shreds can be mixed prior to admission into the cigarette maker. The rate at which the shredding machine discharges a stream of shreds is kept constant by monitoring the density of successive bales or portions of bales and by regulating the speed at which the bales or portions of bales are delivered to the shredding station in dependency on the mass of the respective bales or portions of bales.

摘要： Apparatus for expelling moisture from a continuous stream of tobacco which passes through a conditioning zone defined by a hollow rotary drum-shaped dryer has a control unit employing a computer whose output signal is indicative of the quantity of moisture to be expelled from tobacco per unit of time during travel through the dryer in order to ensure that the final moisture content of tobacco will match a predetermined value. The signal which is generated by the computer is used to regulate a valve in a conduit connecting the conditioning zone with a source of steam. The rate of steam admission or the pressure of admitted steam increases when the quantity of moisture which is contained in tobacco entering the dryer per unit of time decreases and vice versa. This ensures that the total quantity of moisture in the conditioning zone remains at least substantially constant even though the moisture content and/or the quantity of tobacco in the stream entering the dryer varies within a wide range. The wall or walls of the dryer can be indirectly heated by steam. A threshold circuit can be installed between the adjusting device for the steam valve and the output of the computer if the conditioning zone is to receive steam only when the initial moisture content of tobacco or the quantity of tobacco which is admitted into the conditioning zone per unit of time is so low that the wall or walls of the dryer would expel excessive quantities of moisture therefrom.
摘要翻译： 从通过由中空旋转滚筒式干燥器限定的调节区域的连续烟草流排出水分的设备具有控制单元，该控制单元采用计算机，其输出信号表示每单位烟草从烟草中排出的水分量 以便确保烟草的最终含水量与预定值相匹配。 由计算机产生的信号用于调节将调节区域与蒸汽源连接的导管中的阀。 当每单位时间内进入干衣机的烟草中含有的水分量减少时，蒸汽进入速率或允许蒸汽的压力增加，反之亦然。 这确保了即使进入干衣机的流中的水分含量和/或烟草的量变化在宽范围内，调理区中的水分总量仍保持至少基本恒定。 干燥器的壁或壁可以被蒸汽间接加热。 如果调节区仅在烟草的初始含水量或每单位进入调理区的烟草数量时才能接收蒸汽，则可以在用于蒸汽阀的调节装置和计算机的输出之间安装阈值电路 的时间太低，使得干燥器的壁或壁将从其中排出过量的水分。
