Description

Verfahren zur Entwässerung des Preßrückstandes von der Hydrolyse stärkehaltiger Moose. Die Aufgabe, die durch die Erfindung zu lösen ist, besteht darin, die Rückstände, die aus der Hydrolyse von stärkehaltigen Moosen bei ihrer Bearbeitung auf zuckerhaltige Maischen sich ergeben, zweckmäßig zu entwässern. Diese Rückstände sind an sich sehr gut als Brennstoffe verwertbar; für die Wirtschaftlichkeit des Verfahrens zur Herstellung vergärbarer Maischenosmosen ist die Benutzung der Rückstände als Brennstoff von großer Bedeutung. Dieser Benutzung steht aber die Schwierigkeit entgegen, daß diese Rückstände sehr schwer in genügendem Grade zu entwässern sind. Sie halten bei allen Trocknungsversuchen hartnäckig das Wasser fest, so daß es durch die üblichen Mittel, wie Pressen und Trocknen, nicht in genügender Weise aus dem Rückstand zu entfernen ist.Process for dewatering the press residue from hydrolysis of starchy Mosses. The object to be solved by the invention is to remove the residues, those from the hydrolysis of starchy mosses during their processing to sugary ones Mash arise, expedient to dewater. These residues are great in themselves easily usable as fuel; for the economics of the manufacturing process fermentable mash osmosis is the use of the residues as fuel from great importance. This use is opposed to the difficulty that this Residues are very difficult to dewater to a sufficient degree. They stick with everyone Attempts to dry the water stubbornly, so that it by the usual means, such as pressing and drying, cannot be removed from the residue in a sufficient manner is.

Es wurde nun festgestellt, daß der Grund für dieses hartnäckige Festhalten des Wassers in dem in den Rückständen verbliebenen Zuckergehalt zu suchen ist, und daß es ohne weiteres gelingt, den Rückstand in genügender Weise zu trocknen, wenn zuvor dafür Sorge getragen ist, daß der Zucker aus dem Rückstand entfernt wird. Zur direkten Gewinnung als Zucker oder in vergorener Form als Alkohol sind die in Frage kommenden Mengen Zucker zu gering. Es handelt sich also bei der Bearbeitung des Rückstandes lediglich darum, den Zucker zu entfernen oder zu zerstören. Dieses geschieht nach der Erfindung derart, daß der abgepreßte Rückstand entweder mit Wasser verdünnt und dann vergoren wird, bis der Zucker zerstört ist; in diesem Falle läßt sich nach der Vergärung der Rückstand ohne weiteres in genügender Weise abpressen und trocknen.It has now been established that the reason for this persistent clinging of the water is to be found in the sugar content remaining in the residues, and that it is easily possible to dry the residue sufficiently if it has been ensured beforehand that the sugar is removed from the residue. For direct production as sugar or in fermented form as alcohol, the in Ask coming amounts of sugar too low. So it's editing the residue is simply a matter of removing or destroying the sugar. This happens according to the invention in such a way that the pressed residue either with water diluted and then fermented until the sugar is destroyed; in this case leaves After fermentation, the residue is easily pressed off in a sufficient manner and dry.

Unter Umständen genügt es aber auch, den Rückstand mehrere Male mit Wasser anzurühren und das Wasser abzupressen, um zu einem Rückstand zu kommen, der sich ebenfalls bequem entwässern läßt. Nach der Entfernung des Zuckers läßt sich der Rückstand ohne weiteres abpressen und trocknen und gibt ein ausgezeichnetes Feuerungsmaterial, das nicht allein für die Durchführung des Betriebes genügt, sondern sogar noch einen Überschuß von fast zoo Prozent ergibt.However, it may also be sufficient to cover the arrears several times Stir water and squeeze off the water to leave a residue that can also be drained easily. After removing the sugar it can be the residue easily squeeze and dry and gives an excellent Firing material that is not sufficient for the operation alone, but rather even gives a surplus of almost zoo percent.
