Description

  

      Verfahren    und Vorrichtung zur Erwärmung von Obst- und Traubensäften.    Gegenstand     nachstehender    Erfindung ist  ein Verfahren und eine Vorrichtung zur Er  wärmung unvergorener, oder     infolge    Abküh  lung in .der Gärung stockender Obst- und  Traubensäfte auf Gär-     bezw.    Sterilisations  temperatur.  



       Beginn    und Verlauf der Gärung ist unter  anderem abhängig von einer für das Hefe  _     Wachstum    geeigneten Temperatur.  



  Um die bei kalter Witterung gekelterten  Obst- und Traubensäfte auf Gärtemperatur  zu     bringen,    half man sich damit, entweder  kleinere Mengen in Kesseln zu erhitzen und  mit dem kalten Saft zu mischen, oder     durch     . Aussenheizungen, sei es durch Erwärmen der       FasswanJungen    oder     des    Kellerraumes. Ein  solches Vorgehen erwies     .sich    als untauglich,  weil die zur Erwärmung der grossen Gebinde  erforderliche Wärmemenge auf oben ge  nannte Weise nicht innert nützlicher Frist  übertragen     wenden    kann.

   Die inneuerer Zeit  auf den Markt gebrachten Tauchsieder er  wärmen zufolge ihrer aus konstruktiven  Gründen klein gehaltenen Oberfläche die sie  unmittelbar umgebenden Säfte auf so hohe  Temperatur,     ,dass    diese einen     Kochgeschmack       bekommen und zudem     .die    Hefe     abgetötet     wird.  



  Das     vorliegende    Verfahren vermeidet     .die     oben genannten Mängel unter Zuhilfenahme  einer     Vorrichtung    mit     entsprechend    gross  oberflächigen     Heizelementen,        mittelst    der  man imstande ist,     in    -der     Zeiteinheit    sehr  grosse     Wärmemengen    an den zu     erwärmenden     Saft abzugeben.  



  Die Säfte werden beispielsweise mittelst  einer Flüssigkeitspumpe durch. -einen zum  Beispiel elektrisch, oder mit Dampfbeheizten       Durchlaufwärmer,    wie er     üls        Ausführungs-          beispiel    einer zur Ausübung des Verfahrens       gemäss,der    Erfindung dienenden Vorrichtung  in beiliegender Skizze dargestellt ist, ge  pumpt. Es bedeutet 1 ein     kippbares    Gehäuse  mit Schlauchansätzen 2 und 3.

   Die Obstsäfte  treten .durch den     Sühl.auchansatz    2 ein, pas  sieren nach Durchlauf .einer Verteilerplatte d  das zum Schutz gegen Verstopfung mit Obst  bestandteilen angebrachte Sieb 5, erwärmen  sich beim Durchlaufen ,der Heizelemente 6  und     verlassen    den Apparat durch     den     Schlauchansatz 3.

   Die erwärmten Säfte wer  den entweder oben in denselben Behälter zu-      rückgeleitet, von welchem aus durch eine  Pumpe ein stetiger     Kreislauf    so lange unter  halten wird, bis der Inhalt .des Behälters die  Gär-     bezw.        die    Sterilisationstemperatur er  reicht hat, oder es kann durch     entsprechende     Vermehrung -der Heizelemente die Erwär  mung des Saftes schon bei einmaligem Durch  lauf herbeigeführt werden.     Das    Durchströmen  der Säfte durch die     Heizelemente    gewähr  leistet eine intensive     Wärmeabgabe,    wodurch  die Temperatur der Heizelemente so niedrig  gehalten werden kann, dass eine Überhitzung  des Saftes, d. h.

   eine schädigende Beeinflus  sung der Hefe, wie auch die Entstehung eines       Kochgeschmackes    ausgeschlossen ist.



      Method and device for heating fruit and grape juices. The following invention relates to a method and a device for heating unfermented, or as a result of cooling in .der fermentation stagnant fruit and grape juices on Gär- bezw. Sterilization temperature.



       The beginning and course of fermentation depends, among other things, on a temperature suitable for yeast growth.



  In order to bring the fruit and grape juices pressed in cold weather to fermentation temperature, one helped oneself either to heat smaller amounts in kettles and to mix them with the cold juice, or through them. Outside heating, be it by heating the barrel walls or the cellar room. Such a procedure proved to be unsuitable because the amount of heat required to heat the large containers cannot be transferred in the above-mentioned manner within a useful period.

   The immersion heaters that have recently been launched on the market, due to their small surface area for structural reasons, heat the juices immediately surrounding them to such a high temperature that they acquire a cooking taste and, moreover, the yeast is killed.



  The present method avoids the above-mentioned deficiencies with the aid of a device with correspondingly large surface heating elements, by means of which one is able to give off very large amounts of heat to the juice to be heated in the unit of time.



  The juices are passed through, for example, by means of a liquid pump. -a for example electrically, or with steam-heated flow heater, as it is shown in the accompanying sketch, as an example embodiment of a device serving to carry out the method according to the invention. 1 means a tiltable housing with hose attachments 2 and 3.

   The fruit juices enter through the cooling element 2, after passing through a distributor plate d pass through the sieve 5, which is attached to protect against clogging with fruit components, heat up when passing through the heating elements 6 and leave the apparatus through the hose extension 3.

   The heated juices are either returned to the top of the same container, from which a constant circulation is maintained by a pump until the contents of the container have fermented or fermented. the sterilization temperature he has reached, or by increasing the heating elements accordingly, the juice can be heated in a single run. The flow of the juices through the heating elements ensures an intensive heat emission, whereby the temperature of the heating elements can be kept so low that overheating of the juice, i. H.

   a damaging influence on the yeast, as well as the development of a cooking taste, is excluded.
