Description
Filtriervorrichtung, insbesondere zur Bestimmung von Milchschlamm Die Erfindung betrifft eine Filtriervorrichtung zur Bestimmung von Milchschlamm. Es ist bekannt, zur Bestimmung von Milchschlamm und Schmutz Wattescheiben zum Filtrieren der Milch zu verwenden. Diese Wattescheiben werden z. B. mittels eines :Metallringes gegen die Durchtrittsöffnung des Filtriergefäßes gepreßt. Nach dem Filtrieren der betreffenden Milchprobe werden die Wattescheiben auf Papier oder auf Karten aufgeklebt, die mit den erforderlichen Angaben und Bemerkungen versehen werden. Diese Arbeitsweise ist aber sehr unzweckmäßig, da die Wattescheiben im feuchten Zustande leicht aus,#inanderreißen, fasern und sich schlecht aufkleben lassen. Zwecks Vermeidung dieser Übelstände wird daher gemäß der Erfindung zum Filtrieren eine Karte benutzt, die hinreichenden Platz für Vermerke sowie eine Durchlaßöffnung für die zu prüfende Flüssigkeit aufweist, über welcher der Filterstoff befestigt ist.Filtering device, in particular for determining milk sludge The invention relates to a filtering device for determining milk sludge. It is known for the determination of milk sludge and dirt cotton discs for filtering to use the milk. These cotton discs are z. B. by means of a: metal ring pressed against the opening of the filter vessel. After filtering the the milk sample concerned is stuck on the cotton wool discs on paper or on cards, which are provided with the necessary information and comments. This way of working but is very inexpedient, since the cotton discs easily tear apart when wet, fibers and are difficult to stick. In order to avoid these evils, we will therefore, according to the invention, a card is used for filtering, which has sufficient space for notes as well as a passage opening for the liquid to be tested, over which the filter material is attached.
Die Filtrierkarte besteht beispielsweise aus zwei durch Kleben oder Falten und Kleben miteinander verbundenen Papierblättern, welche mit runden oder andere Gestalt besitzenden Löchern der jeweils gewünschten Größe versehen sind, wobei zwischen den beiden Papierblättern der Filterstoff derart eingeschlossen liegt, daß derselbe die Löcher vollkommen deckt. Auch kann die Filtrierkarte aus einem einzigen Blatt Papier bestehen, welches mit einem Loch versehen ist, wobei gleichfalls der Filterstoff derart an dem Blatt Papier befestigt ist, daß das Loch vollkommen abgedeckt ist.The filter card consists for example of two by gluing or Fold and glue interconnected sheets of paper, which are round or other shape owning holes of the desired size are provided, the filter material lying between the two sheets of paper in such a way that that it completely covers the holes. The filter card can also consist of a consist of a single sheet of paper, which is provided with a hole, and also the filter cloth is attached to the sheet of paper in such a way that the hole is perfect is covered.
Die Filtrierkarte wird für den Gebrauch in die Filtriermaschine geschoben, die Milch geht durch den Filterstoff hindurch, und der Schlamm der Milch bleibt darauf zurück. Hierauf wird die Karte aus der Maschine genommen und mit den erforderlichen Angaben versehen.The filter card is pushed into the filter machine for use, the milk passes through the filter cloth and the milk sludge remains back to it. The card is then taken out of the machine and with the required Provide information.
