Description
Verfahren und Vorrichtung zur Temperaturregelung beim Konservieren und Sterilisieren Zusatz zum Zusatzpatent 957 S14 An anderen Stellen hat der Erfinder die Vorteile einer Aufheizung mit hoher und speziell optimaler Aufheizgeschwindigkeit auf die :23ehandlungstemperatur für Pasteurisierung und Sterilisierung beliebiger Stoffe dargelegt. Im Hauptpatent 957 514 ist ferner bereits dlie Bedeutung der Ausgangstemperatur geschildert und die wirtschaftlich vorteilhafte Möglichkeit, die Aufheizung auf die Ausgangstemperatur im Gegenstrom der behandelten Flüssigkeit zu der kalt einströmenden unbehandelten Flüssigkeit vorzunehmen. Dieses Gegenstromprinzip ist an sich bekannt, erfordert aber für den speziellen Anwendungszweck im Zusammenhang mit der Steilaufhizung besondere Maßnahmen, da die Ausgangstemperatur für die Steilaufheizung konstaIlt sein soll, unabhängig von der vorher gegebenen Temperatur der zu behandelnden Flüssigkeit. Die Einregulierung des Gegenströmers so, daß die Eingangstemperatur für die Steilaufheizung konstant ist, bildet Gegenstand dieser Erfindung.Method and device for temperature control during preservation and sterilization addendum to additional patent 957 S14 In other places, the inventor has the advantages of heating with a high and especially optimal heating rate to the: treatment temperature for pasteurization and sterilization of any Substances outlined. In the main patent 957 514 the meaning of the starting temperature is also already mentioned outlined and the economically advantageous way of heating up the outlet temperature in the countercurrent of the treated liquid to that of the cold flowing in untreated liquid. This countercurrent principle is known per se, but required for the special application in connection with steep heating special measures, as the starting temperature for the steep heating remains constant should be, regardless of the previously given temperature of the liquid to be treated. The adjustment of the countercurrent so that the inlet temperature for the steep heating is constant, forms the subject of this invention.
Zur Erleichterung des Verstãndnisstes seien zunächst einige Bezeichnungen festgelegt: Es sei T0 die gegebene Temperatur der zu behandelnden Flüssigkeit, T1 die Temperatur hinter dem Gegenströmer, die der Ausgangstemperatur für die eigentliche Heizstrecke für die Steilaufheizung entspricht, T2 die Behandlungstemperatur, d. h. also die Temperatur, die hinter dem Steilaufheizer vorliegt. To make it easier to understand, let me begin with a few names fixed: Let T0 be the given temperature of the liquid to be treated, T1 the temperature behind the countercurrent, that of the outlet temperature corresponds to the actual heating section for the steep heating, T2 is the treatment temperature, d. H. i.e. the temperature behind the steep heater.
Die Aufgabe ist also, zur Sicherung der gewählten Behandlungstemperatur und zur Erhaltung der Temperaturdifferenz T2-T1 und damit der optimalen Aufheizgeschwindigkeit Maßnahmen zur Konstandhaltung der Temperatur T1 in einer Vorrichtung vorzusehen, deren apparativer Aufbau in der Prinzipskizze der Fig. I dargestellt ist. So the task is to ensure the chosen treatment temperature and to maintain the temperature difference T2-T1 and thus the optimal heating rate To provide measures to maintain the temperature T1 in a device, the structure of which is shown in the schematic diagram of FIG.
Es bezeichnet I den Sammelbehälter für die zu behandelnde Flüssigkeit mit der Temperatur To. I designates the collecting container for the liquid to be treated with the temperature To.
Von hier aus wird die Flüssigkeit durch die Pumpe 2 durch den Gegenströmer 3 (Einströmleitung a) geführt, an dessen Ende sie die Temperatur T1 angenommen haben soll, die durch die später zu schildernde Maßnahme konstant gehalten werden soll. Von hier aus fließt die Flüssigkeit über den Steulaufheizer 4, der für die optimale Aufheizgeschwindigkeit im Zusammenhang mit der festgelegten Temperaturdifferenz T2T.1 ausgelegt ist. Nach Passieren des Heizers 4 fließt die Flüssigkeit über die Verweilstrecke 5, den Gegenströmer 3 (Rückströmleitung b) und den Kühler 6 zur Entnahmestelle.From here, the liquid is passed through the pump 2 through the countercurrent 3 (inflow line a), at the end of which they have assumed the temperature T1 which is to be kept constant by the measure to be described later. From here the liquid flows over the control heater 4, which is responsible for the optimal Heating rate in connection with the specified temperature difference T2T.1 is designed. After passing the heater 4, the liquid flows over the Dwell section 5, the counterflow 3 (return line b) and the cooler 6 to the extraction point.
Das erfindungsgemäße Mittel besteht in der Anbringung einer Nebenschlußleitung zum Gegenströmer. Diese Nebenschlußleitung kann zur Einströmleitung a (Fig. 2, Leitung a') und/oder zur Rückströmleitung b' (Fig. 3, Leitung b') des Gegenströmers vorgesehen werden, wobei durch eine eingebaute Drossel oder ein eingebautes Ventil D, V die Verteilung auf - die beiden Leitungswege gesteuert wird. Diese Drosseln oder Ventile werden von Hand eingestellt oder besser automatisch durch ein Kontaktthermometer, z. B. an der Stelle T0 oder Tl, gesteuert. The means according to the invention consists in attaching a shunt line to the countercurrent. This shunt line can lead to the inflow line a (Fig. 2, line a ') and / or to the return flow line b' (Fig. 3, line b ') of the counterflow by means of a built-in throttle or a built-in valve D, V die Distribution to - the two conduction paths is controlled. These throttles or valves are set by hand or better automatically by a contact thermometer, z. B. at the point T0 or Tl, controlled.
Zunächst sei die Maßnahme der Fig. 2 erläutert. First, the measure of FIG. 2 will be explained.
Der Gegenströmer sei so ausgelegt, daß er bei der tiefsten Temperatur To auf die vorgesehene Temperatur T1 aufheizt. Liegt diese Temperatur To im Betrieb vor, so ist die Drossel bzw. das Ventil DV geschlossen. Liegt die Temperatur To höher, so wird durch Betätigen der Drossel DV der Leitungsweg a' um ein hinreichendes Maß freigegeben, so daß sich die gewünschte Temperatur T1 einstellt. The countercurrent is designed so that it is at the lowest temperature To heats up to the intended temperature T1. If this temperature To is in operation before, the throttle or the valve DV is closed. If the temperature To higher, the conduction path a 'is increased by a sufficient one by actuating the throttle DV Measure released so that the desired temperature T1 is set.
Diese Einstellung der Drossel kann von Hand oder automatisch durch eines der Kontaktthermometer To oder T1 vorgenommen werden. Es muß dabei Vorsorge getroffen werden, daß !die Wiedervereinigung und Mischung der über die beiden Leitungswege a und a' strömenden Flüssigkeitsanteile vor der Meßstelle T1 und dem Heizer 4 erfolgen kann. Die Drossel könnte auch durch ein Ventil ersetzt werden, das durch zwei Kontakte des Kontaktthermometers T1 geöffnet bzw. geschlossen wird. Diese beiden Kontakte grenzen die vorgesehene Temperatur T1 nach oben undunten ab.This setting of the throttle can be done manually or automatically one of the contact thermometers To or T1 can be made. There must be precaution be taken that! the reunification and mixing of the two lines of conduct a and a 'flowing liquid portions take place before the measuring point T1 and the heater 4 can. The throttle could also be replaced by a valve that has two contacts of the contact thermometer T1 is opened or closed. These two contacts limit the intended temperature T1 from above and below.
Bei dem in der Fig. 3 veranschaulichten Weg ist der Nebenschluß b' zur Rückströmleitung b gelegt: er regelt also die Menge der dem Gegenströmer zufließenden auf Temperatur befindlichen Flüssigkeit, mit anderen Worten, die dem Gegenströmer zum Austausch zugeführte Wärmemenge, und führt damit die Einstellung der Temperatur Tl herbei. In the way illustrated in FIG. 3, the shunt b ' to the return flow line b: it regulates the amount of the countercurrent flowing into it liquid at temperature, in other words that of the countercurrent amount of heat supplied for exchange, and thus leads to the setting of the temperature Tl.
Die automatische Regelung erfolgt wiederum zweckmäßig durch das Kontaktthermometer T1 mit den beiden Begrenzungskontakten.In turn, the automatic control is expediently carried out by the contact thermometer T1 with the two limit contacts.
Die Regulierung durch die Nebenschlußleitung b' dürfte der durch die Nebenschlußleitung a' vorzuziehen sein, da im letzteren Falle durch Zuströmen der kalten Flüssigkeit die Gefahr besteht, daß die Regulierung zu unruhig wird. The regulation by the shunt line b 'should be through the shunt line a 'should be preferred, since in the latter case by inflow the cold liquid there is a risk that the regulation becomes too restless.
Es wäre auch, wie schon angedeutet, denkbar, beide Nebenschlußieitungen vorzusehen, wobei die Nebenschlußleitung a' mit eingebauter, von Hand nach Eichung regulierbarer Drossel eine grobe Voreinstellung nach der jeweils vorhandenen Temperatur T0 und die Nebenschlußleitung b' mit eingebautem, vom Kontaktthermometer T1 automatisch gesteuertem Ventil die Feinregulierung übernehmen könnte. As already indicated, it would also be conceivable for both shunt lines to be provided, the shunt line a 'with built-in, by hand after calibration adjustable throttle a rough pre-setting according to the existing temperature T0 and the shunt line b 'with built-in, automatically from the contact thermometer T1 controlled valve could take over the fine adjustment.
