Bisher hat man zum Trocknen von frisch geformten Thonwaaren (Mauersteine, Dachziegel etc.) ausschliefslich die Fähigkeit der Luft ausgenutzt, Wasserdampf aufnehmen und fortführen zu können. Für empfindliche Thone stellt sich hierbei die Schwierigkeit ein, dafs die Fabrikate an den zunächst von dem Luftstrom getroffenen Stellen leicht reifsen, indem hier ein zu schnelles Vortrocknen erfolgt.So far one has had to dry freshly formed clay ware (bricks, roof tiles etc.) exclusively exploited the ability of the air to absorb water vapor and to be able to continue. For sensitive clays the difficulty arises here that the products ripen slightly in the places initially hit by the air stream by Pre-drying is too rapid here.
Um diesem Xiebelstande abzuhelfen und ein vollkommen " gleichmäfsiges Trocknen in geschlossenen, nicht ventilirten Räumen durchzuführen, benutzt der Erfinder bei seinem Verfahren die bekannte Fähigkeit des Chlorcalciums oder ähnlicher Salze, Wasser begierig anzuziehen. Die frisch geformten Thonwaaren werden in einen Raum gebracht, der nach seiner Füllung vollkommen geschlossen wird. Im Innern ist auf siebartig durchlochten Blechen trocknes Chlorcalcium ausgebreitet, welches den eingesetzten Thonwaaren das Wasser an allen Stellen gleichmäfsig entzieht. Das flüssig gewordene Chlorcalcium fliefst durch die siebartigen Auflageflächen in einem darunter angeordneten Gerinne nach aufsen, um hier abgedampft und zu neuer Verwendung in den trocknen Zustand übergeführt zu werden. Die beim Abdampfen der Lauge entwickelten Wasserdämpfe werden durch Rohrleitungen fortgeführt, die in den Trockenräumen angeordnet sind, um die eingesetzten zu trocknenden Fabrikate nach Wunsch erwärmen und im Winter gegen Frost schützen zu können.In order to remedy this Xiebelstande and a completely "even drying in closed, To carry out unventilated spaces, the inventor uses in his method the well-known ability of calcium chloride or similar salts to eagerly draw water. The freshly formed pottery is brought into a room that is completely closed after it has been filled. Inside, dry calcium chloride is spread out on sieve-like perforated sheets, which The clay ware used removes the water evenly at all points. The one that has become liquid Calcium chloride flows through the sieve-like support surfaces in one below Flume upwards to be evaporated here and transferred to the dry state for new use. the The water vapors developed during the evaporation of the lye are carried through pipelines arranged in the drying rooms in order to be able to heat the products to be dried as required and to protect them against frost in winter.
