Definitions

  • aqueous solution having a pH of about 6 to about 10 and containing, in an amount up to about percent by weight of the tobacco material, a substance selected from the group consisting of inorganic base, organic base, alkali metal and ammonium salts and mixtures thereof to form an aqueous slurry.
  • the slurry is subjected to a temperature of not greater than about 100 C. for a period of up to about minutes to form a pulp.
  • To the resulting pulp is added from about 0.5 to about 3 percent by weight based on the weight of the tobacco of a binding agent. Products are shaped from the resulting pulp and the shaped products are dried at a temperature of from about to about C.
  • the cellular units of tobacco plant leaves are held together by a substance contained in the middle lamella.
  • the substances of such middle lamellae consist, in addition to hemicellulose, pentosans and lignins, of highpolymeric polygalacturonic acid, more or less esterified with methanol, said acid comprising a large number of galacturonic acid units (varying according to the treatment of the tobacco). These are linked with a 1,4-glucosidic bond. Long molecules similar to the kind present in cellulose are formed by this linking.
  • the partially esterified polygalacturonic acid is called pectin.
  • Pectin is contained in tobacco in an amount of up to 20 percent. Pectin has the task in the tobacco of holding together the cellular unit. The fixing of the adhesive mechanism, primarily to guarantee water insolubility, occurs in plants by entrance of calcium and/or magnesium in the carboxylic group liberated by saponification of the ester. It is supposed that the free carboxylic group in two adjacent pectin molecules is occupied by magnesium or calcium. The calcium and magnesium salts are water insoluble. The high-polymeric, saponifiable and/or hydrolyzable products present in tobacco can be degraded to water soluble or swellable and adhesive substances, respectively.
  • binding agents in relatively large amounts, preferably in amounts of more than 10 percent, whereby the individual tobacco particles were held together to form a sheet.
  • the flavor of the resultant product was negatively influenced.
  • the binding agents gave rise to additional costs.
  • the present invention provides ,a method for the production of shaped tobacco products not sufiering from the indicated disadvantages.
  • A. preparing an aqueous slurry comprising 1. an aqueous solution having a pH prior to admixture with tobacco of about 6 to about 10 and containing, in an amount up to about percent by weight of the tobacco material, a substance selected from the group consisting of inorganic bases, organic bases and alkali-metal and ammonium salts of organic and inorganic acids.
  • comminuted tobacco material having an average grain size of up to about 100p. which has not been subjected to a preliminary washing, soaking or leaching treatment, is mixed with an aqueous solution having a pH of about 6 to about 10 and containing, in an amount up to about 15 percent by weight of the tobacco material, a substance from the group of inorganic bases, organic bases, alkali metal salt and ammonium salts and mixtures thereof.
  • the thus formed aqueous slurry is subjected to a temperature of not greater than 100 C., for a period of up to about 45 minutes to form a pulp.
  • the resultant pulp is then formed into a shaped product and the resultant shaped product is dried at a temperature of about 60 to about 100 C.
  • the tobacco-starting material can be fermented (cured), partially fermented or unfermented tobacco or tobacco waste or shreds such as arise in the tobacco industry. This is inclusive of veins, stalks, tobacco dust and stems and the like. It is not necessary in this invention to conduct a preliminary washing step and thus the starting material may contain impurities such as sand and the like.
  • the starting material can be that obtained from light tobacco or light tobacco waste or shreds as well as from dark tobaccos or dark tobacco waste or shreds.
  • tobaccos having differing pH values as well as mixtures thereof can be employed as starting materials.
  • so-called light, preferably uncured, oven-dried or sun-dried (redriedl) tobaccos which have a pH value of less than 6 in the main current smoke, such as Virginia, Orient, Smyrna or waste thereof, for example, veins or stalks, may be incorporated into comminuted cigar tobaccos and/or waste thereof having a pH value of more than 6 in the main current smoke for processing.
  • One of the essential benefits of the present invention is that the tobacco product obtained according to the method, even when produced only from tobacco waste materials, corresponds substantially to the color of the tobacco material used as starting material.
  • the products obtained differ in aroma only insignificantly, if at all, from the tobacco-starting material initially employed.
  • the comminuted tobacco-starting material is mixed with an aqueous solution having a pH of about 6 to about 10 to form an aqueous slurry.
  • the aqueous slurry is subjected to a temperature of not greater than 100 C., for a period of up to about 45 minutes to form a pulp.
  • the high-polymeric, saponifiable and/or hydrolyzable substances present in the comminuted tobacco-starting material are made swellable or adhesive. It is important that the slurry be subjected to a temperature which is not greater than 100 C., in view of the fact that substantially higher temperatures will adversely affect the product obtained.
  • the aqueous solution which is utilized to form the slurry has a pH of from about 6 to about 10 and preferably from about 7.5 to about 9.0.
  • the pH of the aqueous solution is adjusted prior to the addition of the comminuted tobacco-starting material to form the slurry. No adjustment in the pH is made after the addition of the comminuted tobacco material.
  • the aqueous solution consists of at least one chemical substance which is either present per se in the tobacco-starting material or has a composition such that its aqueous solution yields, at least partially, the same ions as those ions which are present in the original tobacco-starting material.
  • alkali metal and ammonium salts and mixtures thereof of organic or inorganic acids, free organic bases and free inorganic bases are alkali metal and ammonium salts and mixtures thereof of organic or inorganic acids, free organic bases and free inorganic bases.
  • inorganic bases there may be mentioned potassium hydroxide, sodium hydroxide, ammonia and the like.
  • Ethylenediamine may be mentioned as an example of an organic base.
  • alkali metalsalts or ammonium salts there may be mentioned those of organic acids, as for example, formic acid, acetic acid, carbonic acid, malic acid, citric acid and tartaric acid. Salts of phosphoric acids are also utilizable. Mixtures of these basic salt materials can be utilized to achieve the desired pH of the aqueous solution.
  • the concentration of the aqueous solution, or the amount of the basic or salt materials used in the aqueous solution for the regeneration of the high-polymeric materials depends on the one hand, upon the quality and upon the composition of the tobacco-starting material to be treated, and, on the other hand, upon the desired properties of the shaped tobacco product. In general good results are obtained with a concentration of the material of up to about percent by weight of the dry substance based upon the weight of the tobacco-starting material to be treated. In particular the concentration will generally range from about 0.1 to about 15 percent by weight of the tobacco starting material although 0.1 to 5 percent is preferable.
  • This binding agent may be an adhesive or adhesive mixture such as, for example, raw pulp, ethyl, acetyl, methyl, carboxymethyl, hydroxyethyl cclluloses, pectins, carob bean kernel meal, agar-agar, manucol (sodium alginate), Suar gum, or other mucouslike adhesive substances.
  • this binder material is utilized in an amount up to about 3 percent by weight based on the weight of the tobacco-starting material.
  • the amount of the adhesive or adhesive mixture employed will range from about 0.5 up to about 3 percent by weight based on the weight of the tobacco. Higher amounts will adversely affect the tobacco aroma.
  • fibrous material can also be added to the pulp a fibrous material as, for example, mineral fibers, asbestos fibers, in order to increase the tensile strength of the shaped product. Such materials must be chosen so as not to interfere with the flavor and color of the resultant product. In general any fibrous material which resists burning under conditions whereby the tobacco is smoked will be suitable.
  • the fibrous material can be employed in amounts of up to about 2 percent by weight based on the weight of the tobacco-starting material.
  • Additional materials can, if desired, be added to the resultant pulp prior to shaping.
  • catalytically active substances such as titanium compounds, manganese compounds, and the like, for example, titanium dioxide, manganese sulfate, manganese citrate or tartrate and/or plasticizers such as for example glycerol, sorbite, diethylene glycol and the like.
  • a significantly improved water insolubility of the sheets can also be obtained by the further addition to the pulp of preferably calcium or magnesium salts, e.g., calcium formate, calcium lactate, calcium gluconate, magnesium acetate, magnesium citrate, magnesium gluconate, magnesium formate, and the like or mixtures of the indicated materials.
  • calcium or magnesium salts e.g., calcium formate, calcium lactate, calcium gluconate, magnesium acetate, magnesium citrate, magnesium gluconate, magnesium formate, and the like or mixtures of the indicated materials.
  • the resultant pulp is shaped into the desired form and dried at a temperature of from about 60 to about 100 C.
  • the pulp is passed in a desired thickness onto a belllike support and dried substantially on this support whereupon a dried sheet material is obtained and removed from the support in a per se conventional manner.
  • a plasticizer as, for example, glycerol, sorbite, or diethylene glycol.
  • the plasticizer causes the sheet to maintain a certain plasticity. Amounts of from about 2 to about 5 percent by weight based upon the weight of tobacco of the plasticizer can be employed.
  • the belt moves through a drying zone wherein the shaped material is dried and the sheet material is then removed from the belt by per se conventional means, as for example, by the use of a doctor blade.
  • the drying of the shaped material may be in a conventional manner such as lR-irradiation, warm or hot air, or by direct heating of the belt.
  • the shaped tobacco products produced according to the present invention can be used as cover sheets for cigars, cigarillos and the like. They can also be used for the production of tobacco for cigarettes by reducing such sheets in a conventional manner to very small pieces, thus allowing the ultimate use of all waste tobacco materials resulting in the tobacco industry.
