Method for preparing multi-layer reconstituted tobacco leaves

Abstract

The invention relates to a method for preparing multi-layer reconstituted tobacco leaves. The method comprises the steps that tobacco leaves and tobacco stem mixed slurry are concentrated through a bottom layer flow sending system, then feeding-to-mesh and forming are performed through a bottom layer flow slurry box, a bottom layer mesh part gravity dewatering box and a vacuum dewatering box are used for surface water removal, the tobacco leaves and the tobacco stem mixed slurry are concentrated through a top layer flow sending system, then feeding-to-mesh and forming are performed through a top layer flow slurry box, the surface water is removed through the bottom net gravity dewatering tank and the vacuum dewatering box, tobacco powder is evenly spread on a leaf base formed on a bottom layer, and then a top layer leaf base is composited with the bottom layer leaf base and shaped through a press part. The method can obtain the leaf base of a sandwich type novel electronic cigarette, and the method can make full use of the tobacco powder, and can make the reconstituted tobacco leaf suction feeling closer to natural tobacco leaves.

Description

technical field [0001] The invention relates to the technical field of novel tobacco preparation, in particular to a method for preparing multi-layer reconstituted tobacco leaves. Background technique [0002] At present, the production process of new-type tobacco adopts the same or similar method as that of reconstituted tobacco leaves. Tobacco powder is used to extract and pulp together with the leaf group, and to form the pulp together with the stem group. Due to the small particle size of tobacco powder, This method causes the tobacco powder to lose a large amount of concentrated white water during molding and dehydration, resulting in a high concentration of concentrated white water and a greater pressure on sewage treatment. At the same time, the loss of tobacco powder results in a low product yield, and the tobacco powder cannot play a role in the product. . And the existing technology has no way to directly add powdered solid spices. The existing technology can only...

Problems solved by technology

[0002] At present, the production process of new-type tobacco adopts the same or similar method as that of reconstituted tobacco leaves. Tobacco powder is used to extract and pulp together with the leaf group, and to form the pulp together with the stem group. Due to the small particle size of tobacco powder, This method causes the tobacco powder to lose a large amount of concentrated white water during molding and dehydration, resulting in a high concentration of concentrated white water and a greater pressure on sewage treatment. At the same time, the loss of tobacco powder results in a low product yield, and the tobacco powder cannot play a role in the product.

And the existing technology has no way to directly add powdered solid spices. The existing technology can only dissolve the powdered solid spices into the coating solution for application. Due to the high temperature of the coating solution, the aroma components of the powdered solid spices volatilize greatly. It is necessary to increase the amount of addition to ensure the aroma quality of the product and increase the production cost
