    • Reconstituted tobacco sheets manufactured from tobacco dust and binder are described herein. More particularly, the tobacco dust has a mean particle size in the range of from about 60 mesh to about 400 mesh to afford reconstituted tobacco sheets having about 80% to about 90% tobacco content with improved quality and survivability. The reduced particle size of the tobacco dust allows an increase in the solids content of the slurry without an increase in slurry viscosity. The increased solids content reduces the drying load of the cast sheet thereby allowing an increased production rate. The reconstituted tobacco sheets may be prepared from a slurry comprising tobacco dust and binder that may be subjected to a means for removing air trapped within the slurry before casting the slurry into sheets. An apparatus for determining the amount of air trapped within the slurry prepared according to the process of the present invention is also described herein.
    • 本文描述了由烟草粉尘和粘合剂制成的重组烟草片。 更具体地,烟草粉末的平均粒度在约60目至约400目的范围内,以提供具有改善质量和生存性的烟草含量约80%至约90%的重构烟草片。 烟草粉尘的减小的粒度允许浆料的固体含量的增加而不增加浆料粘度。 增加的固体含量降低了铸片的干燥负荷,从而允许增加的生产率。 重构烟草片可以由包含烟草粉尘和粘合剂的浆料制备,所述浆料可以在将浆料浇铸成片材之前经受​​用于除去捕集在浆料内的空气的装置。 本文还描述了一种用于确定根据本发明的方法制备的浆料中捕集的空气量的装置。
