Bei der vorliegenden Erfindung werden gemischte, stärkehaltige Substanzen zur Zerkleinerung der Stärkezellen unter grofsem Druck durch kleine Oeffnungen gedrückt, so dafs sie mit grofser Geschwindigkeit durch dieselben hindurchtreten. Auf diese Weise wird abwechselnd der Druck in Geschwindigkeit und die Geschwindigkeit in Druck umgewandelt, was auf die Zellen die beabsichtigte Wirkung hat, indem sowohl die kleinsten wie auch die gröberen Partikelchen, gleichviel, ob sie noch in ihrer Hülse eingebettet sind oder nicht, gegen einander schlagen, sich gegenseitig brechen und die in den Zellen enthaltene Stärke freimachen.In the present invention, mixed starchy substances are used for crushing of the starch cells pressed under great pressure through small openings, so that they with pass through them at great speed. In this way the Pressure is converted into speed and the speed is converted into pressure, which affects the cells has the intended effect, in that both the smallest and the coarser particles, no matter whether they are still embedded in their shell or not, they hit each other, each other break each other and release the starch contained in the cells.

Fig. ι zeigt den Apparat, welcher aus einer Anzahl Injectoren und Ejectoren A besteht, welche mit Dampfeintrittsrohren (die Pfeile zeigen dieselben an) versehen und mit Pumpen oder Druckapparaten B verbunden sind.Fig. Ι shows the apparatus, which consists of a number of injectors and ejectors A , which are provided with steam inlet pipes (the arrows indicate the same) and connected to pumps or pressure apparatuses B.

Die Maische oder das Getreide, welches zuvor mit Hülfe eines gewöhnlichen Mischapparates mit Wasser vermengt worden ist, wird mittelst der Pumpe bei B¹ in den ersten Injector A¹ gedrückt, welcher einen Ueberlauf α wie ein gewöhnlicher Griffard-Injector haben kann. Aus dem Injector gelangt die Maische in die nächste Pumpe, von da in den zweiten Injector und so fort nach Pumpe und Injector durch den ganzen Apparat. Die Anzahl der Injectoren oder Ejectoren richtet sich nach der Art des zu behandelnden Getreides. Es ist nicht absolut nothwendig, Pumpen anzuwenden, wenn nicht die Temperatur der Maische zu hoch ist, damit der Injector von selbst zu arbeiten anfange. Injectoren· kommen nicht immer bei hohen Temperaturen von selbst in Gang, und deshalb wendet man eine durch Kraft getriebene Pumpe an, um den Injector in Gang zu setzen. Aber ein einmal in Gang gebrachter Injector kann in einem anderen mit Leichtigkeit den Druck, welchen eine Pumpe abgeben würde, erzeugen und unterhalten.The mash or the grain, which has previously been mixed with water with the help of an ordinary mixer, is pressed by means of the pump at B ¹ into the first injector A ¹ , which can have an overflow α like an ordinary Griffard injector. From the injector the mash goes to the next pump, from there to the second injector and so on after the pump and injector through the whole apparatus. The number of injectors or ejectors depends on the type of grain to be treated. It is not absolutely necessary to use pumps unless the temperature of the mash is too high for the injector to start working on its own. Injectors do not always start up by themselves at high temperatures and therefore a power pump is used to start the injector. But an injector, once started, can easily generate and maintain the pressure that a pump would deliver in another.

Wenn andererseits aber gewünscht wird, die Temperatur oder irgend eine andere Eigenschaft der Maische theilweise unverändert beizubehalten, so ist es besser, die Kraft zum Durchtreiben der Maische durch die In- und Ejectoren von Pumpen, welche selbst durch Kraft getrieben werden, zu erzeugen. Das gewünschte Resultat würde dann ohne Anwendung von Dampf in den Injectoren erreicht werden, vorausgesetzt, dafs die Röhren der Ejectoren entsprechend construirt sind, so dafs sie entweder beim Eintritt konisch oder sonst zweckentsprechend gestaltet sind, oder so, dafs die in dem Ejector hervorgebrachte Geschwindigkeit gleich oder beinahe gleich jener würde, welche dem Druck der Maische an der Ausflufsöffhung des Ejectors entspricht. Die Maische würde beim Austritt aus dem Ejector eine solche Geschwindigkeit erlangt haben, dafs sie durch die Eintrittsöffnung des nächsten Injectors in Wirklichkeit mit derselben Kraft eintritt, mit welcher sie den Ejector verlassen hat, obgleich sie in der Zwischenzeit durch die freie Luft ging, und treibt sich selbst durch den Ejector mit einem Druck, welcher dem des Rohres oder Kessels gleich ist, welcher deri Ejector mit Druck versieht minus dem Verlust durch Reibung. Eine oder mehrere Pumpen würden nothwendig sein, um den Verlust durch Reibung zu ersetzen oder um, wenn es verlangtOn the other hand, if desired, temperature or some other property to keep the mash partially unchanged, it is better to have the strength to propel it through the mash through the injectors and ejectors of pumps, which are themselves driven by force will generate. The desired result would then be in without the use of steam the injectors, provided that the tubes of the ejectors correspond accordingly are designed so that they are either conical on entry or otherwise appropriately designed or so, that the velocity produced in the ejector is the same or almost the same that which would be equal to the pressure of the mash at the outlet opening of the ejector is equivalent to. The mash would have such a speed when exiting the ejector have achieved that through the inlet opening of the next injector they in reality communicate with the same Force enters, with which it left the ejector, although it has in the meantime went through the open air, and propels itself through the ejector with a pressure which is equal to that of the pipe or kettle that the ejector pressurizes minus the loss by friction. One or more pumps would be necessary to get through the loss To replace friction or order if required

Claims

will add or intensify the pressure.

In this way, the starchy cells can be broken by mechanical pressure which is converted into speed and the cells and pods at one at a temperature that does not affect the diastasis.

In some cases, especially with regard to the malt, the diastase can be in an or two operations of the mashed malt in an injector system, as Fig. ι shows, and subsequent separation of the liquid from the larger and solid constituents, then Adding fresh liquid and re-treating the mash in the apparatus or be removed in a second row of injectors.

Furthermore, as said before, the mash can be treated with steam, either with superheated or ordinary steam mixed with water, and driven through the injectors.

The liquid extract obtained from the broken starch cells can make the previous thinner Extract can be added or mixed with it. Should the extract be concentrated so it can be added to fresh mash or fresh grain to make a To form mash, which is then driven back through the injector.

In Fig. 3 a construction of the double injector is shown. It has an annular passage formed by the core b on the one hand and by an outer annular vapor path on the other hand; also has the same b \ a displaceable cone Fig. 4 shows a bimanual number of injectors. The steam inlet c is inside the cone d, which contains the mash, while the funnels d ^{1 are surrounded} by outer annular steam paths or chambers.

Fig. 5 is a kind of ejector tube for partially separating the liquid from the solid components of the mash. The liquid goes through the slots which can be seen in the flue pipe at E.

The injectors and ejectors can be in rows or bundles, in sheets or otherwise arranged, also in connection with pressurized boilers or chambers or similar.

One can also use the husk part of the separate the floury or dusty part of the grain, and then separate them through the injector system let go and the liquid to be used of one part according to the proportion the liquid of the other judge.

When separating the liquid from the solid constituents of the mash when the same verläfst the Injectorsystem, one zweckmäfsig uses the ejector shown in Fig. 5 which discharges the mash on the separation cone E. The latter has layers of radially arranged wires with one layer below the other. The mash falls out of the tube / onto the cone E, is thereby divided, and the liquid part flows through E into the funnel m, while the solid components fall to one side. The impact of the mash on the cone E also has the purpose of comminuting the pods and breaking the cells open by the blow. In general, wherever speed is generated in the course of the mash, be it in the injector or when leaving it, an obstacle can be placed everywhere, which has a scraping, rubbing or impacting effect.

When the extract is filtered, the husky part and the floury part can after them have gone through the injector system, come together in one vat.

Pat ENTr claims:

ι. The filtration or separation of the liquid extract obtained from the starch from the solid components of the mash in a vat equipped with a separation device, Fig. 5 is provided.

2. An apparatus for breaking the starch cells, consisting of an alternating row of injectors or ejectors A and pumps B, ^{FIG. 1} , which injectors have a central core b and a cone b 1 that can be displaced by a toothed wheel, FIG. 3 , for the purpose of letting the mash, mixed with steam, emerge in an annular jet.
