Embodiment 1
[0040] The selection experiment of embodiment 1 tobacco sheet preparation conditions
[0041] 1. Selection of extraction conditions
[0042] There are many ways to extract tobacco waste, such as adding appropriate chemicals or direct cold and hot water. In order to ensure that the quality of tobacco active ingredients is less damaged and to achieve as much recycling as possible, the choice of extraction method very important. The present invention adopts extraction, which actually adopts a three-stage countercurrent extraction process.
[0043] Each part of the stem is extracted three times, and the secondary extraction solution, the first extraction solution and water are used as the extractant in turn; each part of the extraction agent is used to extract three parts of the stem, which are the second extraction stem, the first extraction stem and the new stem.
[0044] The extraction rate of each step of each stalk and each extract was studied, and one extraction was used a...
Embodiment 2
[0079] Example 2 Tobacco flakes with roasted sweet aroma
[0080] Tobacco sheet of present embodiment, preparation process flow chart sees attached figure 1 shown, with figure 1 Among them, 1 represents the raw material pretreatment section, 2 represents the extraction concentration reaction and blending section, 3 represents the slurry preparation section, 4 represents the papermaking forming coating section, and 5 represents the finished product post-processing section. The present invention mainly relates to the 2nd and 3rd sections . 6 is the prepared tobacco stem raw material, 7 is the prepared tobacco powder raw material; 8 represents the grinding and peeling of the tobacco stem raw material, 9 is the soaking of the tobacco stem, 10 is the solid-liquid separation of the tobacco stem extract, and 11 is the extraction of the tobacco powder.

Embodiment 3
[0089] Example 3 Tobacco flakes with woody aroma and roasted sweet aroma
[0090] This embodiment provides a method for preparing tobacco sheet, the process is the same as that in Embodiment 2, and the operation steps of alcohol precipitation and extraction are set up, specifically including the following steps:
[0091] (1) After grinding and peeling the tobacco stems, soak them in water (the ratio of solid to liquid is 1:15, Kg:L) and extract them; The mass ratio of stem and tobacco powder is 2:1. The extraction adopts a three-stage countercurrent tank extraction process at 80°C for 30 minutes.
[0092] (2) Squeeze and filter the extract obtained in step (1) successively, and perform solid-liquid separation treatment;
[0093] (3) Disperse the solids in water respectively, beating and defibrating, after defibrating, combine and prepare the pulp, fiber broom, and make the tobacco fiber into a fiber sheet base; the tobacco stems are defibrated, and the degree of defibration ...
