PATENTAMT.PATENT OFFICE.
Während bei der jetzigen Methode, die Melasse zu osmosiren, jeder Osmoseapparat mit frischem Wasser gespeist wird, wobei der Salzgehalt des Osmosewassers, nachdem es den Apparat verlassen, ein relativ geringerer ist, so kann man auf folgende Weise eine vielfach concentrirtere Lösung mit derselben Wassermenge erhalten: Man stellt je drei Osmoseapparate etagenförmig neben einander und führt das vom obersten Apparat abfliefsende Osmosewasser, welches also die gewöhnliche Concentration hat, auf den demnächst tiefer stehenden zweiten Apparat. Auf dem Einlaufrohr α befindet sich ein runder Behälter b, welcher durch eine Wand c getheilt ist, so dafs beide dadurch entstandenen Räume nur am Boden mit einander communiciren. In diesem Behälter liegt unten eine Schlange von Kupfer, welche fortwährend mit frischem Dampf angewärmt ist. Indem das Osmosewasser dieses so angewärmte Gefäfs durchläuft, kann man ihm die Temperatur zurückgeben, welche es auf dem ersten Apparat verloren hat. Nachdem das Wasser den zweiten Apparat verlassen, ist seine Concentration viel bedeutender, als nach dem Verlassen des ersten Osmoseapparates. Vom zweiten Apparat geht die concentrirtere Lösung auf den am tiefsten stehenden dritten Apparat, der wiederum mit einer Vorrichtung zum Anwärmen des Osmosewassers versehen ist. Angestellte Versuche in der Praxis ergaben für das Osmosewasser nach dem Verlassen des ersten Apparates 3 bis 50 Brix, nach dem Verlassen des dritten Apparates 12 bis 15° Brix. Der Vortheil der Erfindung liegt in der Thatsache, dafs man zum Eindampfen dieses Osmosewassers weniger Wärme und Zeit gebraucht, da es von vornherein einen gröfseren Salzgehalt hat, als es beim bisherigen Verfahren der Fall war.While in the present method of osmosis of the molasses each osmosis apparatus is fed with fresh water, the salinity of the osmosis water being relatively less after it leaves the apparatus, a much more concentrated solution can be obtained with the same amount of water in the following manner : Three osmosis devices are placed next to each other in a tiered manner and the osmosis water flowing off from the uppermost device, which therefore has the usual concentration, is fed to the second device, which will soon be lower. On the inlet pipe α there is a round container b, which is divided by a wall c , so that the two spaces thus created communicate with one another only at the bottom. At the bottom of this container lies a snake made of copper, which is constantly warmed with fresh steam. As the osmosis water runs through this vessel that has been warmed up in this way, it can be given back the temperature it lost on the first apparatus. After the water leaves the second apparatus, its concentration is much more important than after leaving the first osmosis apparatus. From the second apparatus, the more concentrated solution goes to the deepest third apparatus, which in turn is provided with a device for heating the osmosis water. Employees tests in practice were 12 to 15 ° Brix for the osmosis water after leaving the first apparatus 3 to 5 0 Brix, after leaving the third apparatus. The advantage of the invention lies in the fact that less heat and time are required to evaporate this osmosis water, since it has a higher salt content from the start than was the case with the previous process.
