Definitions

• the invention relates to a smokable, coherent film made from shredded, vegetable materials and / or tobacco waste on a surface with a water-insoluble film.
• the shredded tobacco is washed out with a relatively large amount of water and the washing liquid is partially recirculated.
• the matted tobacco fibers with a relatively high proportion of cellulose fibers are poured onto a sieve belt. Due to the high moisture content, considerable amounts of energy are required for drying to the desired final moisture.
• the ground tobacco is mixed with about 10 times the amount of water and an appropriate proportion of binding agent to a pulp and poured onto a steel belt. This method also requires a large excess of moisture a relatively high amount of energy for drying.
• Binders water and / or solvents, generally in a smaller amount than the dry matter content, are added to the shredded tobacco, and the paste-like mass obtained after the mixing is applied using pressure by extrusion and / or shaping by means of rollers and / or belts formed into foils and then dried to the desired final moisture with a relatively low energy requirement.
• the film produced with the extruder process and / or roller system namely with little water and using pressure, generally has a lower filling capacity, which reduces the energetic advantages that are present in its production compared to the aforementioned systems. It is believed that this is due to the compact nature or the less porous structure compared to the film produced with the paper process or slurry system.
• tobacco dust is sprinkled onto a film consisting of binder and tobacco.
• a film consisting of binder and tobacco.
• tobacco dust is sprayed with various binder solutions and dried.
• the binder used to prevent dust abrasion can consist of methyl cellulose, dextrin, pectin, alginate, starch and the like.
• the moist film is dried before application, preferably spraying, of the coating material and dried again to the desired final moisture after coating.
• a tobacco film with a thin, hydrophobic coating is produced on at least one surface by forming a tobacco film from finely divided tobacco and a water-soluble binder in aqueous solution, the film dries, the dried film is then coated with an alcoholic solution of ethyl cellulose and the coating finally dries. So this requires a double drying and also a long conveyor belt, which is uneconomical and space-consuming.
• the film surface was coated with various binders, both water-soluble and water-insoluble, for which purpose, for example, solutions or suspensions of sodium carboxymethyl cellulose, guar gum, pectin, alginate or locust bean gum were used, if appropriate also contained crosslinking agents such as glyoxal or other dialdehydes.
• binders both water-soluble and water-insoluble, for which purpose, for example, solutions or suspensions of sodium carboxymethyl cellulose, guar gum, pectin, alginate or locust bean gum were used, if appropriate also contained crosslinking agents such as glyoxal or other dialdehydes.
• the smokable films produced from comminuted, vegetable materials and / or tobacco waste are not fully satisfactory with regard to their various properties, and the object of the invention is therefore to create a coherent, smokable film with good smoke quality which is known from the prior art Overcomes disadvantages, and which is characterized above all by an increased filling capacity and high moisture resistance. Furthermore, an economical and simple method for producing such a film is to be provided.
• a smokable film of the type mentioned at the outset which is obtainable by deforming the vegetable materials and / or tobacco waste with binders and water, the proportion of which is less than that of the dry substance used, between deformation elements under pressure, the deformed, coherent and still moist film is coated at a moisture content of 30 to 50% with a solution or suspension which contains at least one water-soluble, modified pectin from the group of low-esterified pectin with a degree of esterification of less than 40% and / or amidated, contains low-esterified pectin with a degree of amidation of over 15%, the modified pectin is brought into contact with divalent and / or trivalent metal ions and the coated film is dried, the concentration of the modified pectin on the film surface, based on the dry weight of the finished productEnd product, at least 0.5 percent by weight.
• a tobacco film with high filling capacity and high moisture resistance is then produced using extruder processes and / or roller processes.
• the energy requirement for the production of such films is far below that of the slurry process or of the paper process, and the films which can be obtained hereafter also have a significantly better smoke quality.
• the degree of esterification of the low-esterified pectins suitable according to the invention can generally range from 0.5 to 40%, with those having a degree of esterification of 10 to 40% being preferred owing to the better water solubility of the somewhat higher esterified pectins.
• amidated, low-esterified pectins can also be used according to the invention, namely pectins in which some of the ester groups (methyl ester groups) have been replaced by amide groups or in which some of the free carboxyl groups have been converted to amide groups.
• such amidated, low-esterified pectins have a degree of amidation of at least 15%, pectins with a degree of esterification of 35 to 20% and correspondingly a degree of amidation of 15 to 30% being preferred .
• Combinations of one or more low-esterified pectins with one or more amidated, low-esterified pectins can of course also be used.
• low-esterified pectins whose degree of esterification is below 10% are also suitable according to the invention for the film coating, since such pectins give water-insoluble films of good stability even with relatively small amounts of divalent and / or trivalent metal ions.
• their alkali metal salts such as sodium pectinate, or also their ammonium salts are advantageously used for the preparation of the coating solution or coating suspension.
• the degree of esterification of such pectinates is preferably between 0.5 and 10%, and in particular between 1 and 5%.
• the film according to the invention produced by means of printing systems shows an equally good or even better filling capacity than a film which was produced by the paper process or slurry process, the improved properties of such films, in particular also after their machine processing to cigarettes, are preserved.
• the divalent and / or trivalent metal ions preferably consist of calcium ions and / or magnesium ions and / or aluminum ions.
• the filling capacity of the products coated and cut with the water-insoluble film according to the invention is on average about 20 to about 60% higher than the filling capacity of products manufactured in the same way and having the same composition, but uncoated, even if the latter have a higher binder content.
• the preferred concentration of the modified pectin in the coating solution or coating suspension is 2 to 8 percent by weight, so that the viscosity of the coating solution or coating suspension at the application temperature is 5000 mPa s to 60,000 mPa s.
• the films produced in this way already show improved filling capacity when the concentration of the modified pectin on its surface, based on the dry weight of the finished end product, is at least 0.5 percent by weight.
• the concentration of the modified pectin on the product surface is preferably between 1.2 and 1.5 percent by weight, based on the dry weight of the finished end product.
• the calcium ions and / or magnesium ions and / or aluminum ions necessary to form a water-insoluble film can either be mixed into the coating solution or coating suspension or the comminuted, vegetable materials and / or tobacco waste.
• the ions are advantageously added to the coating solution or coating suspension in the form of water-insoluble salts, such as in the form of CaC0 3 , Ca 3 (PO 4 ) 2 , A1P0 4 , MgCO 3 and the like. If they are added to the comminuted, vegetable materials and / or tobacco waste, then soluble salts, such as lactates, sulfates and the like, can also be used.
• the water-insoluble film is created by exchanging the divalent or trivalent metal ions ; with cations of the soluble, modified pectins during the drying of the coated structure.
• concentrations of the above ions are, depending on the type of application and Coating material, preferably between 0.5 and 20 percent by weight, based on the amount of modified pectin when added to the coating solution or suspension, and preferably between 0.5 and 10 percent by weight, based on the dry weight of the finished end product, if it was comminuted , vegetable materials and / or tobacco waste are added. These limits are guidelines, so that, depending on the type of modified pectin, the necessary amounts of ions are below or above.
• Tobacco foils were produced in the same way as in Example 1 and coated on a surface with different amounts of low-esterified (degree of esterification of about 20 to 22%) pectin.
• the coating solution contained calcium ions in an amount of 2%, based on the low-esterified pectin.
• films which are produced from so-called tobacco substitute materials namely ground parts of plants, for example husks of cocoa beans, husks of coffee beans or wood cellulose.
• Film B was produced from the same material and additives as film A, but with the difference that it was not coated but instead contained 1.5% by weight of the same sodium pectinate in the base material.
• the film C was produced from the same material and additives as the films A and B, but with the difference that the production was carried out by the paper process.
