Description
Verfahren zum Herstellen einer Hülle für Preßhefegtücke Es ist allgemein üblich, Preßhefe in Stücken zu einem halben Kilogramm geformt und in Pergament oder andere Papiersorten eingewickelt auf den Markt zu bringen. Dabei hat @es sich erwiesen, daß das verwendete Papier zweckmäßig nicht undurchlässig sein sollte (Stanniol oder Wachspapier), da ein Gasaustausch zwischen Hefe und Außenluft erforderlich ist. Andererseits begünstigteine zu große Durchlässigkeit des Papiers das schnelle Austrocknen und Bröckligwerden des Hefestückes. Besonders schädlich wirkt sich bei zu undurchlässiger Hülle der Umstand aus, daß an dieser bei .äußerer Abkühlung stets Wasser kondensiert. Diese Feuchtigkeit führt dann leicht zu Schimmelbildung. Da die klimatischen Bedingungen (Temperatur, Luftfeuchtigkeit), denen die Hefe des Handels ausgesetzt ist, stark veränderlich sind, ist es, um für die Hefe die jeweils beste Durchlässigkeit der Hülle zu besitzen, notwendig, diesle bezüglich ihrer Permeabilität stets den äußeren Umständen anzupassen. Die Erreichung dieses Zieles ist Zweck der vorliegenden Erfindung.Method of making a casing for press yeast bags It is general common, pressed yeast in pieces to half a kilogram and in parchment or Bringing other types of paper onto the market in wrapped form. It has proven that that the paper used should not be impermeable (tinfoil or Wax paper), as gas exchange between yeast and outside air is required. On the other hand, too great a permeability of the paper promotes rapid drying out and crumbling of the yeast lump. It is particularly harmful if it is too impermeable Sheath from the fact that water always condenses on this when external cooling. This moisture easily leads to mold growth. As the climatic conditions (Temperature, humidity) to which the yeast of the trade is exposed are changeable, it is in order for the yeast to have the best permeability in each case It is necessary to have a shell, this is always the outer one in terms of its permeability To adapt to circumstances. Achieving this goal is the purpose of the present invention.
Es wurde nun gefunden, daß solche selbsttätig den Gas- und Flüssigkeitsaustausch regelnde Häute vorzüglich aus besonders behandelter getrockneter Hefe gebildet werden können.It has now been found that such automatic gas and liquid exchange regulating skins are formed from specially treated dried yeast can.
Als besonders vorteilhaft erwies es sich z. B., zu diesem Zwecke lebende Trockenhefe mit Wasser zu mischen, so daß sie eine breiige oder plastische Dichte schon bei Wesentlich geringeren Feuchtigkeitsgraden erhält als normale Preßhefe. Die so bereitete Masse wird auf das Preßhefestück aufgetragen (aufgestrichen, aufgepr2ßt, aufgewalzt o. dgl.), worauf man sie zu einer dünnen, papierartigen Haut eintrocknen läßt. Dies kann beispielsweise in einem Trockenraum mit Luft von nicht zu geringem FeuchtigkeitsgƒIra@t er=folgen; den man nach und nach gegebenenfalls unter Wechsel des Trockenraumes verringert.It was found to be particularly advantageous, for. B., living for this purpose Mix dry yeast with water so that it has a mushy or plastic density retains much lower levels of moisture than normal compressed yeast. The mass prepared in this way is applied to the pressed yeast piece (painted on, pressed on, rolled on or the like), whereupon they dry up to a thin, paper-like skin leaves. this can for example in a drying room with air from do not follow too low a moisture content; which one gradually possibly reduced by changing the drying room.
Die so erzeugte Haut besitzt die geforderten Eigenschaften in hohem Maße, und es kann wegen ihrer mechanischen Festigkeit unter Umständen auf «;eitere Verpackung verzichtet werden, so daß die Stücke in dieser Form in Kartons verpackt werden können. Die letzteren werden dabei zweckmäßig zylindrisch gestaltet, so daß bei der Verpackung zwischen ihnen entsprechende Luftkanäle entstehen.The skin produced in this way has the required properties to a high degree Dimensions, and because of its mechanical strength it can under certain circumstances become fester Packaging can be omitted, so that the pieces are packed in this form in cardboard boxes can be. The latter are expediently designed cylindrical so that corresponding air ducts are created between them during packaging.
Es ist jedoch auch möglich, die Bildung einer Hefehaut durch entsprechende Oberflächenbehandlung des Hefestückes selbst zu erzielen, und zwar in der Weise, daß man die Oberfläche der Preßhefestücke mittels eines der bekannten H-efetrockenverfahreti bis zur Hautbildung trocknet.However, it is also possible to prevent the formation of a yeast skin by appropriate To achieve surface treatment of the yeast lump itself in such a way that that the surface of the pressed yeast pieces by means of one of the known H-efetrockenverfahreti dries until a skin forms.
