Process for utilizing tobacco dust
First Claim
1. A process for affixing tobacco dust to a comminuted tobacco-type product selected from the group consisting of tobacco, tobacco substitute and reconstituted tobacco, comprising the steps of mixing tobacco dust, a powdered water soluble hydrocolloid, and the tobacco-type product, spraying a water miscible organic solvent over this mixture, followed by an aqueous solution of a hydrocolloid and continuing the mixing until a substantially dry product is obtained, wherein:
- a. the amount of tobacco-type product is at least 60% of the weight of the total mixture;
b. the amount of tobacco dust is at most 25% of the weight of the total mixture;
c. the amount of powdered water soluble hydrocolloid is at least 20% by weight of the amount of tobacco dust;
d. the amount of water miscible organic solvent is at most 10% of the weight of the total mixture;
e. the amount of aqueous solution of a hydrocolloid is from 2 to 7% of the weight of the total mixture;
wherein further the water miscible organic solvent is selected from the group consisting of ethanol, isopropanol, propylene glycol, glycerol, diethylene glycol, triethylene glycol and butylene glycol, and wherein the water soluble hydrocolloids are selected from the group consisting of vegetable gums, microbial gums, starch derivatives, cellulose derivatives, gelatin, casein, polyvinylalcohol and saccharose.

Abstract
A process for utilizing tobacco dust by affixing it to cut, shredded or otherwise comminuted tobacco, reconstituted tobacco or tobacco substitute by thoroughly mixing tobacco dust, a powdered water soluble hydrocolloid, optionally an organic solvent, the comminuted tobacco, reconstituted tobacco or tobacco substitute, water or an aqueous solution of the hydrocolloid and optionally an additional quantity of the comminuted tobacco, reconstituted tobacco or tobacco substitute and continuing the mixing until a dry or almost dry product is obtained. The water soluble hydrocolloid may partly or completely be replaced by micro-encapsulated flavors, so that flavored tobacco products are obtained.
