Description

Antischaummittel für die Hefe- und Zuckerindustrie Zusatz zum Patent 1 050 289 Im Hauptpatent wird ein Antischaummittel beschrieben, das aus einer Mischung von Ölen aus der Erdölraffination mit Silikonen, insbesondere Polydimethylsiloxanen, in Form einer Wasser-in-Öl-Emulsion, besteht. Die Emulsion der Öle in Wasser wird dabei mit einer Emulsion der Silikone vermischt bzw. dieses Gemisch durch Druck bei 10 bis 20 atü homogenisiert. Antifoam agent for the yeast and sugar industry. Patent addition 1 050 289 The main patent describes an antifoam that consists of a mixture of oils from petroleum refining with silicones, especially polydimethylsiloxanes, in the form of a water-in-oil emulsion. The emulsion of the oils in water becomes mixed with an emulsion of the silicone or this mixture by pressure Homogenized at 10 to 20 atm.

Es wurde nun gefunden, daß das Einkapseln der Silikone durch Melasse oder alkalische Medien, wie Rohrsaft bei der Zuckergewinnung, Würze bei der Hefegewinnung, und damit das Unwirksamwerden der Silikone noch weiterhin verringert werden kann, wenn man dem gemäß Patent 1 050289, das aus einer Mischung von Olen aus der Erdölraffination mit Silikonen, insbesondere Polydimethylsiloxanen, in Form einer Wasser-in-Öl-Emulsion besteht, noch einen Zusatz von Stearinsäure, Äthylenglykol, Glycerinmonooleat, Glycerindistearat, Stearyl-, Mondecyl- oder Arachylalkohol allein oder in Mischung miteinander gibt. It has now been found that the encapsulation of the silicones by molasses or alkaline media, such as cane juice when extracting sugar, wort when extracting yeast, and so that the ineffectiveness of the silicones can be further reduced, if one considers that according to patent 1 050289, which consists of a mixture of oils from petroleum refining with silicones, especially polydimethylsiloxanes, in the form of a water-in-oil emulsion consists, nor an addition of stearic acid, ethylene glycol, glycerol monooleate, glycerol distearate, There are stearyl, mondecyl or arachyl alcohol alone or in admixture with one another.

Die so erhaltenen Antischaummittel sind gegenüber Säuren und Alkalien üblicher Konzentration beständig und voll wirksam; für die Anwendung genügen schon geringe Mengen, z. B. 0,3 O/o, bezogen auf fertige Hefe. The antifoams obtained in this way are resistant to acids and alkalis usual concentration constant and fully effective; enough for the application small amounts, e.g. B. 0.3 O / o, based on finished yeast.

1. 30Teile Fettalkohol C20-C22 werden auf 700 C erwärmt und mit 50 Teilen eines Weißöls (Paraffinbasis) versetzt. Zu diesem Ansatz werden Silikone (Polydimethylsiloxanreihe und Methylsiloxanreihe) unter hoher Tourenzahl (S= 000 bis 14000) eingebracht. Die so erhaltene Mischung wird mit 0,5 bis 6/0 eines Emulgators der nichtionogenen Gruppe (z. B. ein Polyglykolätherderivat) vermengt. In einem zweiten Gefäß werden 150 Teile Wasser mit 2 Gewichtsteilen des Gesamtansatzes Äthylenglykol und 1 bis 2 Gewichtsteilen (vom Gesamtansatz) eines Polyglykolätherfettalkohols innig vermischt. Bei einer Umdrehungszahl von 12000 bis 14000 pro Minute wird dem Öl-Silikon-Ansatz der Wasseransatz beigegeben. 1. 30 parts of fatty alcohol C20-C22 are heated to 700 C and mixed with 50 Parts of a white oil (paraffin base) are added. Silicones become this approach (Polydimethylsiloxane series and methylsiloxane series) with a high number of revolutions (S = 000 up to 14000). The mixture obtained in this way is mixed with 0.5 to 6/0 of an emulsifier the non-ionic group (e.g. a polyglycol ether derivative). In one The second vessel is 150 parts of water with 2 parts by weight of the total batch of ethylene glycol and 1 to 2 parts by weight (of the total batch) of a polyglycol ether fatty alcohol intimately mixed. At a speed of 12,000 to 14,000 per minute, the Oil-silicone approach added to the water approach.

Die Bildung der Wasser-Ol-Emulsion ist nach etwa 2 bis 3 Minuten vollzogen. Die so erhaltene Emulsion ist im Bereich von 28 bis +800 C (vorübergehend bis + 1100 C) beständig.The formation of the water-oil emulsion is complete after about 2 to 3 minutes. The emulsion obtained in this way is in the range from 28 to +800 C (temporarily to + 1100 C) resistant.

2. 16,5 Teile Glycerindistearat werden mit 33 bis 44 Teilen Glvcerinmonooleat auf 700 C erwärmt und mit 220 Teilen Weißöl (Basis Paraffinöl) gemischt. 2. 16.5 parts of glycerol distearate are mixed with 33 to 44 parts of glycerol monooleate heated to 700 ° C. and mixed with 220 parts of white oil (based on paraffin oil).

Diesem Ansatz werden 2 bis 21 Teile Silikone der Reihen wie in 1 beschrieben bei Umdrehungszahlen von 12 000 bis 14000 pro Minute zugesetzt. This approach uses 2 to 21 parts of silicone in the series as in 1 described added at speeds of 12,000 to 14,000 per minute.

In einem zweiten Behälter werden 240 Teile Wasser mit 2 bis 11 Teilen Emulgator der nichtionogenen Gruppe (wie unter 1 geschildert) und 2,2 Teile Äthylenglykol gemischt. In a second container, 240 parts of water are mixed with 2 to 11 parts Emulsifier of the nonionic group (as described under 1) and 2.2 parts of ethylene glycol mixed.

Beide Ansätze werden nach dem Schema Wasserin-Öl bei einer Umdrehungszahl von 12000 bis 14000 pro Minute zusammengegeben. Die Emulsionsbildung ist nach etwa 2 Minuten abgeschlossen. Both approaches are based on the water-in-oil scheme at one speed put together from 12,000 to 14,000 per minute. The emulsification is after about 2 minutes completed.

Das nach dieser Rezeptur erhaltene Antischaummittel ist von -28 bis +1100 C (vorübergehend bis + 1160 C) beständig. The antifoam obtained according to this recipe is from -28 to +1100 C (temporarily up to + 1160 C) resistant.
