Description

  

  Zusatzpatent zum Hauptpatent Nr. 450 995    Verfahren     zur        Herstellung    von Tabakfolien    Im Hauptpatent ist ein     Verfahren    zur Herstellung  von Tabakfolien     geoffenbart,    welches dadurch gekenn  zeichnet ist, dass man Tabakmaterial zwecks.

   Erreichung  einer     Eigenklebefähigkeit    in einem     schwach    sauren  bis schwach alkalischen Medium     behandelt,    die ent  standene breiige Masse hierauf in Abwesenheit von  tabakfremden     Klebstoffzusätzen    einer bandförmigen       Unterlage        zuführt    und auf dieser Unterlage weitgehend  trocknet und das     folienartige    Trockengut von der       Unterlage        loslöst.     



       ,Als    Tabakmaterial verwendet man gemäss Haupt  patent z. B. Tabakblätter,     Tabakblattfragmente,          Schnittabakabfälle,        Fermentationsabfälle,    Rippen, Ta  bakstaub usw. Es sei in diesem     Zusammenhang    noch       festgehalten,    dass man bei Verwendung von beliebigen       Tabakabfällen        schlechtester    Qualität noch gute     ResulL          tate        erzielen        kann.     



  Wie     bereits    im Hauptpatent erwähnt, ist das zur  Regenerierung der im Tabakmaterial vorhandenen Pek  tine erforderliche     pH    nicht an starre     Grenzwerte    ge  bunden. Es hat sich in der Tat .gezeigt, dass man bei       pH-Werten    in einem Bereich von 3-11 gute     Resultatre     erzielt.

   Bei gewissen     Zigarrentabaksorten    kann man mit  einem     pH    von 7,5 bis 9     hervorragende        Resultate    erzie  len, während' mit gewissen     Zigarettensorten        bei    einem       pH    Bereich von 5-8     ausgezeichnete        Resultate    erreicht  werden     konnten.    Die     Erfindung    sei aber keineswegs auf  diese     Werte    eingeschränkt.  



  Es wurde nun festgestellt, dass man eine noch bes  sere     Regenerierung    der Pektine erzielt, wenn sie in  einem Medium, welches ein     pH    von 3-11 aufweist  und mindestens     eine    freie organische oder anorga  nische Säure und/oder mindestens ein     Erdalkali-    und/  oder     A.mmoniumsalz    einer     organischen        oder    anorga  nischen Säure enthält, erfolgt. Dabei geht man vorzugs  weise so vor, dass man     Tabakstaub    mit     wässrigen     Lösungen freier organischer oder     anorganischer    Säuren,  z.

   B.     Zitronensäure,    Ameisensäure, Essigsäure, Oxal-    säure, Weinsäure, Milchsäure,     Äpfelsäure,    Trauben  säure,     Zitronensäure,        Propionsäure    usw., verschiedener  Phosphorsäuren, werd. Salzsäure,     verd.    Schwefelsäure,  oder mit     wässrigen    Lösungen von     Erdalkalisalzen        oder          Ammoniumsalzen    solcher Säuren, wie z.

   B.     Calcium-          laktat,        Calciumacetat    und     dergleichen    oder     Ammonium-          formiat    und dergleichen, behandelt.     Überdies    können  noch Puffersysteme, z. B.     Sörensenpuffer,        Acetatpuffer          usw.,    zugegeben werden.  



  Man kann     selbstverständlich    auch Mischungen sol  cher Säuren oder     Mischungen    von Alkali- und     Erd-          alkalisalzen    von Alkali- bzw.     Erdalkalisalzen    und       Ammoniumsalzen    oder Mischungen von Säuren     mit     beliebigen Vertretern der soeben     erwähnten    Salze ver  wenden.  



  Die     Behandlung    des Tabakmaterials kann in der  im     Hauptpatent    beschriebenen Weise erfolgen.    <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. Nach dem     Abkühlen    wer  den 20%     (berechnet    auf Tabakgewicht)     Ammonium-          formiat    oder ein Gemisch     stöchiometrischer    Mengen  Ameisensäure     techn.    und Ammoniak     techn.    unter gutem  Rühren zugegeben. Nach kurzer Zeit     entsteht    eine  breiige, viskose Masse, sie     wird    nach Zugabe von 5 bis  <B>10%</B> Weichmacher (berechnet auf Tabakgewicht), wie  z.

   B.     Glycerin,        Diäthylenglycol    usw., in gewünschter  Schichtdicke auf ein     VA-Stahlband    aufgetragen. Das     pH     der     Suspension    ist abhängig vom verwendeten Tabak.  Es liegt bei Zigarettentabaken     zwischen    5,0 und 7,0.

    Die Trocknung geschieht unter den     herkömmlichen     Methoden wie     IR-Bestrahlung,    Warm-     oder    Heissluft  oder durch direkte Erwärmung des Bandes, das Ab  lösen durch die übliche Methode des     Abschabens.         <I>Beispiel 2</I>  1,0 kg fein gemahlener Tabak wird mit 4 kg einer  5 ?     igen        Ammoniumformiatlösung    bzw. mit 4 kg Wasser,  die     stöchiometrische    Mengen     Ameisensäure    und Ammo  niak enthalten, aufgeschlämmt. Die Mischung wird    unter Rühren     wähnend    l5-30 Minuten auf 75-85  C  erwärmt.

   Nach dem Abkühlen und nach Zugabe von  5 % Weichmacher wird der Brei in     gewünschter    Dicke  auf ein     V4A-,Stahlband    aufgetragen.



  Additional patent to the main patent No. 450 995 Process for the production of tobacco foils In the main patent a process for the production of tobacco foils is disclosed, which is characterized in that tobacco material is used for the purpose.

   Achieving a self-adhesive ability treated in a weakly acidic to weakly alkaline medium, the resulting pulpy mass is then fed in the absence of non-tobacco adhesive additives to a tape-shaped base and largely dries on this base and detaches the film-like dry material from the base.



       , According to the main patent z. B. tobacco leaves, tobacco leaf fragments, cut tobacco waste, fermentation waste, ribs, tobacco dust, etc. It should be noted in this context that you can still achieve good results when using any tobacco waste of the poorest quality.



  As already mentioned in the main patent, the pH required to regenerate the pek tine present in the tobacco material is not tied to rigid limit values. Indeed, it has been shown that good results are obtained at pH values in the range of 3-11.

   With certain types of cigar tobacco, excellent results can be achieved with a pH of 7.5 to 9, while excellent results could be achieved with certain types of cigarettes at a pH range of 5-8. The invention is in no way restricted to these values.



  It has now been found that an even better regeneration of the pectins is achieved when they are in a medium with a pH of 3-11 and at least one free organic or inorganic acid and / or at least one alkaline earth and / or A. . Contains ammonium salt of an organic or inorganic acid, takes place. The preferred way of doing this is to use tobacco dust with aqueous solutions of free organic or inorganic acids, eg.

   B. citric acid, formic acid, acetic acid, oxalic acid, tartaric acid, lactic acid, malic acid, grape acid, citric acid, propionic acid, etc., various phosphoric acids, are. Hydrochloric acid, dilute sulfuric acid, or with aqueous solutions of alkaline earth salts or ammonium salts of such acids, such as.

   B. calcium lactate, calcium acetate and the like or ammonium formate and the like treated. In addition, buffer systems, e.g. B. Sörensen buffer, acetate buffer, etc. are added.



  It is of course also possible to use mixtures of such acids or mixtures of alkali and alkaline earth salts of alkali or alkaline earth salts and ammonium salts or mixtures of acids with any representatives of the salts just mentioned.



  The treatment of the tobacco material can be carried out in the manner described in the main patent. <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) ammonium formate or a mixture of stoichiometric amounts of formic acid techn. and ammonia techn. added with thorough stirring. After a short time, a pulpy, viscous mass is formed. After adding 5 to 10% plasticizer (calculated on tobacco weight), such as.

   B. glycerine, diethylene glycol, etc., applied 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.

    The drying is done using conventional methods such as IR radiation, warm or hot air or by direct heating of the tape, the solve from the usual method of scraping. <I> Example 2 </I> 1.0 kg of finely ground tobacco is mixed with 4 kg of a 5? igen ammonium formate solution or 4 kg of water containing stoichiometric amounts of formic acid and ammonia, slurried. The mixture is heated to 75-85 ° 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.
