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.
