preparation example Construction
[0033] The invention provides a preparation method of a dry-process tobacco sheet, comprising the following steps:
[0034] a) mixing the rubber powder with water to obtain a compound adhesive solution;
[0035] b) mixing tobacco powder with water to obtain tobacco powder slurry;
[0036] c) mixing the compounded adhesive solution, smoke powder slurry and atomizing agent to obtain a coating solution;
[0037] d) coating the coating liquid on the front and back sides of the tobacco base sheet, and drying to obtain a tobacco sheet;
[0038] Described step a) and step b) have no order restriction;
[0039] in:
[0040] The gum powder is selected from two of sodium carboxymethylcellulose, guar gum, konjac gum, xanthan gum, flaxseed gum, sodium alginate, hydroxypropyl methylcellulose and sodium silicate;
[0041] In the step a), the mixing temperature is 50-60°C.
[0042] see figure 1 , figure 1 The process flow chart of the present invention is to prepare the dried tobacco ...
