   Ein Teil der in diesem Arbeitsgang gewonnenen Flüssigkeit kann dann in der gleichen Weise zur Impfung des vierten Ansatzes verwendet werden usw. 



   Von der aus dem zweiten Ansatz gewonnenen Lösung liefen in einer Zeit von 13 Minuten durch eine Nutsche von 20   cm2   Filterfläche unter einem Druck von 20 mm   Quecksilbersäule   eine Menge von 100   cm3   klar hindurch. Von der aus dem dritten Ansatz gewonnenen Lösung liefen in einer Zeit von drei Minuten durch eine Nutsche von 20   cm2     Filterfläche   unter einem Druck von 20 mm Quecksilbersäule eine Menge von 100   cm3   klar ab, während von der aus dem ersten Ansatz gewonnenen Lösung unter den gleichen Bedingungen 100 cm3 eine Zeit von 20 Minuten brauchten. 



   An Stelle der für jeden Ansatz erforderlichen Menge von 175 kg Salzsäure   (220 Bé)   können auch je 100 kg Schwefelsäure   (600 Bé)   verwendet werden.

   Some of the liquid obtained in this operation can then be used in the same way for inoculating the fourth batch, etc.



   A clear amount of 100 cm3 of the solution obtained from the second batch ran in a time of 13 minutes through a suction filter with a 20 cm2 filter surface under a pressure of 20 mm of mercury. From the solution obtained from the third batch, an amount of 100 cm3 clearly drained off in a time of three minutes through a suction filter of 20 cm2 filter area under a pressure of 20 mm mercury column, while from the solution obtained from the first batch under the same conditions 100 cm3 took 20 minutes.



   Instead of the 175 kg of hydrochloric acid (220 Bé) required for each batch, 100 kg of sulfuric acid (600 Bé) can also be used.

PATENT-ANSPRUCH : Verfahren zur Erzielung leichter Filtrierbarkeit der bei der Gewinnung von Weinsäure durch Zersetzung weinsäurehaltiger, schleimige und kolloidale Bestandteile enthaltender Rohstoffe, wie Weinhefe, mit Mineralsäuren erhaltenen Lösungen durch Erhitzen der wässerigen Aufschlämmungen bzw. PATENT CLAIM: Process for achieving easy filterability of the solutions obtained with mineral acids in the extraction of tartaric acid by decomposition of raw materials containing tartaric acid, slimy and colloidal components, such as wine yeast, by heating the aqueous slurries or Lösungen der Rohstoffe vor oder während ihrer Zersetzung unter Druck, dadurch gekennzeichnet, dass den wässerigen Aufschlämmungen bzw. Lösungen der Rohstoffe vor der Druckerhitzung, je nach der Rohstoffart veränderliche Mengen der Flüssigkeit zugesetzt werden, welche bei dem vorhergehenden Arbeitsgang aus weinsäurehaitigen Rohstoffen durch Druckerhitzung bis zur Koagulation der schleimigen und kolloidalen Bestandteile und nachheriger Zersetzung mittels Mineralsäuren gewonnen wurde. Solutions of the raw materials before or during their decomposition under pressure, characterized in that the aqueous slurries or solutions of the raw materials before the pressure heating, depending on the type of raw material, variable amounts of the liquid are added, which in the previous operation from tartaric acid-containing raw materials by pressure heating up to Coagulation of the slimy and colloidal components and subsequent decomposition using mineral acids was obtained.
