Description
Verfahren zur Herstellung von Tabakfolien Das Hauptpatent betrifft ein Verfahren zur Her stellung von Tabakfolien, welches dadurch gekennzeich net ist, dass man Tabakmaterial zwecks Erreichung einer Eigenklebefähigkeit in einem schwach sauren bis schwach alkalischen Medium behandelt, die entstandene breiige Masse hierauf in Abwesenheit von tabakfrem den Klebstoffzusätzen einer bandförmigen Unterlage zu führt und auf dieser Unterlage weitgehend trocknet und das folienartige Trockengut von der Unterlage loslöst.
Als Tabakmaterial verwendet man gemäss Haupt patent vorzugsweise zerkleinertes Tabakmaterial, wie z. B. Tabakblätter, Tabakblattfragmente, Schnittabak abfälle, Fermentationsabfälle, Rippen, Tabakstaub usw. Man hat also die Möglichkeit, aus kleinen, ja selbst kleinsten Tabakstücken Folien beliebiger Länge und Breite herzustellen.
Es hat sich nun gezeigt, dass die Regenerierung der Pektine auch in einem Medium, das mindestens ein Ammoniumsalz einer organischen oder anorganischen Säure oder ein Gemisch stöchiometrischer Mengen der entsprechenden Säure und Base enthält, erfolgt.
<I>Beispiel 1</I> Folie aus Zigarettentabaken oder Abfällen aus der Zigarettenfabrikation inklusive Rippen.
1,0 kg fein gemahlener Tabak wird in 4 Teilen Wasser aufgeschlämmt und während 15-30 Minuten auf etwa 75-80 C erwärmt. Nachdem Abkühlen wer den 20 % (berechnet auf Tabakgewicht) eines Gemisches stöchiometrischer Mengen Ameisensäure techn. und Am moniak techn. unter gutem Rühren zugegeben. Nach kurzer Zeit entsteht eine breiige, viskose Masse, sie wird nach Zugabe von 5-10 % Weichmacher (berechnet auf Tabakgewicht), wie z. B. Glycerin, Diäthylenglycol usw., in gewünschter Schichtdicke auf ein VA-Stahlband auf getragen. Das pH der Suspension ist abhängig vom verwendeten Tabak. Es liegt bei Zigarettentabaken zwi schen 5,0 und 7,0.
Die Trocknung geschieht unter den herkömmlichen Methoden wie IR-Bestrahlung, Warm oder Heissluft oder durch direkte Erwärmung des Ban des, das Ablösen durch die übliche Methode des Ab- schabens.
<I>Beispiel 2</I> 1,0 kg fein gemahlener Tabak wird mit 4 kg Was ser, die stöchiometrische Mengen Ameisensäure und Ammoniak entsprechend einer 5 % igen Ammoniumfor- miatlösung enthalten, aufgeschlämmt. Die Mischung wird unter Rühren während 15-30 Minuten auf 75 bis 85 C erwärmt. Nach dem Abkühlen und nach Zugabe von 5 % Weichmacher wird der Brei in gewünschter Dicke auf ein V4A-Stahlband aufgetragen.
Wenn bei Verwendung von Zigarettenabfällen, Rip pen oder anderen Tabaken höhere Anforderungen an die Reissfestigkeit oder Elastizität gestellt werden, kann nach Beispiel 1 und 2 so verfahren werden, dass nach der Pektinspaltung und vor dem Auftragen auf das Stahl band ein Zusatz geringer Mengen (1-5 % berechnet auf Tabakgewicht) von Bindemitteln, wie Carboxymethyl- cellulose (CMC) und ihre Derivate, stattfindet.
Auch die Wasserlöslichkeit der Tabakfolie kann auf diese Weise in merklicher Weise verringert werden. <I>Beispiel 3</I> Zur Erzielung einer besseren Reissfestigkeit und Ela stizität kann nach der Spaltung der Pektine auch ein Zusatz von 1-3 % Ca- bzw. Mg-Salzen, z. B. Lactate, Citrate usw., oder eine Kombination von diesen Sal zen mit kleinen Mengen CMC erfolgen.
Anstelle dieser Salze können auch die Gemische von Laugen und Säuren in stöchiometrischen Verhält nissen verwendet werden.
Process for the production of tobacco foils The main patent relates to a process for the Her position of tobacco foils, which is characterized in that tobacco material is treated in a weakly acidic to weakly alkaline medium in order to achieve self-adhesive properties, the resulting pasty mass then in the absence of non-tobacco adhesive additives leads to a band-shaped base and largely dries on this base and detaches the film-like dry material from the base.
According to the main patent, the tobacco material used is preferably crushed tobacco material, such as. B. tobacco leaves, tobacco leaf fragments, cut tobacco waste, fermentation waste, ribs, tobacco dust, etc. So you have the opportunity to produce films of any length and width from small, even the smallest pieces of tobacco.
It has now been shown that the pectins are also regenerated in a medium which contains at least one ammonium salt of an organic or inorganic acid or a mixture of stoichiometric amounts of the corresponding acid and base.
<I> Example 1 </I> Foil made from cigarette tobacco or waste from cigarette manufacture including ribs.
1.0 kg of finely ground tobacco is suspended in 4 parts of water and heated to about 75-80 ° C. for 15-30 minutes. After cooling who the 20% (calculated on tobacco weight) of a mixture of stoichiometric amounts of formic acid techn. and Am moniak techn. added with thorough stirring. After a short time, a mushy, viscous mass is formed. After adding 5-10% plasticizer (calculated on tobacco weight), such as. B. glycerin, diethylene glycol, etc., worn in the desired layer thickness on a VA steel strip. The pH of the suspension depends on the tobacco used. For cigarette tobacco it is between 5.0 and 7.0.
Drying is done using conventional methods such as IR radiation, warm or hot air or by heating the tape directly, and removal using the customary method of scraping.
<I> Example 2 </I> 1.0 kg of finely ground tobacco is slurried with 4 kg of water containing stoichiometric amounts of formic acid and ammonia corresponding to a 5% ammonium formate solution. The mixture is heated to 75 to 85 ° C. for 15-30 minutes while stirring. After cooling and after adding 5% plasticizer, the paste is applied to a V4A steel belt in the desired thickness.
If higher demands are made on the tensile strength or elasticity when using cigarette waste, ribs or other tobacco, the procedure according to example 1 and 2 can be that after the pectin has been split and before it is applied to the steel band, small amounts (1- 5% calculated on tobacco weight) of binders such as carboxymethyl cellulose (CMC) and its derivatives.
The water solubility of the tobacco film can also be reduced in this way in a noticeable manner. <I> Example 3 </I> To achieve better tensile strength and elasticity, after the pectins have split, an addition of 1-3% Ca or Mg salts, e.g. B. lactates, citrates, etc., or a combination of these Sal zen with small amounts of CMC.
Instead of these salts, mixtures of alkalis and acids can also be used in stoichiometric proportions.
