Defibering and fiber-adding process and equipment of tobacco stems of rolling process reconstituted tobacco

Abstract

The invention discloses a defibering and fiber-adding process of tobacco stems of rolling process reconstituted tobacco, which comprises the following steps: (a) adding the tobacco stems without impurities into a soaking pool, adding appropriate amount of water to soak for 24-36h, spooning and dewatering to a natural state without separating out water; (b) putting the dewatered tobacco stems and water according to the weight proportion of 1:2-3 into a tank body of special tobacco stem defibering equipment for defibering for 10-30min, obtaining suspended fiber liquid with uniform size; and (c)mixing the fiber liquid obtained in the step b with slice glue according to the mass proportion of 1:1-1.5 into tobacco stem fiber-added glue stuff. The invention also discloses tobacco stem defibering equipment, a plurality of fixed cutters are uniformly arranged on the inner wall of the tank body along the circumference, a movable cutter assembly is arranged in the tank body and is connected with a stand in a cantilever way, the movable cutter assembly is provided with two sets of movable cutters, and a driver is linked with the movable cutter assembly through a drive assembly. The invention replaces expansive needlebush-bleaching chemical pulp, not only enables tobacco slices not to contain wood gases, but also greatly lowers the production cost.

Description

technical field [0001] The invention relates to a tobacco processing technology, in particular to a process for defibrating and fiberizing reconstituted tobacco leaves and stems by a rolling method. Background technique [0002] The roll-pressed reconstituted tobacco leaf first appeared in Japan. It is made by using the waste materials of the cigarette industry, namely tobacco stems, tobacco stems and smoke foam, which are crushed into 80-120 mesh tobacco powder and pressed with a roller by adding a binder. . In the 1970s, my country's tobacco scientific and technological workers also successfully developed rolling tobacco sheets according to domestic specific conditions, and gradually popularized and applied them in the tobacco industry. [0003] In order to further improve the quality and effective utilization rate of reconstituted tobacco leaves by rolling method, many domestic cigarette factories are exploring the fibering technology of tobacco sheets. Because it is ne...

Problems solved by technology

These two methods all have defects to a certain extent. The main problem of the dry addition method is that the length of the fiber is destroyed after the wood pulp board is crushed, which affects the effective utilization of the fiber; the second is that the density of the wood pulp fiber and the smoke powder is different. , it is easy to cause uneven mixing, resulting in unstable physical properties of the flakes

The disadvantages of the wet addition method are that the process is complicated, the investment is large, and the cost is high; the second is that the fiber addition is uneven, easy to agglomerate, and the fiber is not fully utilized, white spots are prone to appear in the made sheet, and the fiber consumption is large

The fatal disadvantage of the above fiber adding methods is that they have to buy expensive imported wood pulp fiberboard, which greatly increases the production cost of the cigarette factory, and the addition of wood pulp fiber increases the woody gas in the tobacco sheet, compared with the non-fiber sheet Poor taste
