Description

Kältemischung, aus salzsauren, salpetersauren und schwefelsauren Salzen der Alkalien und Ammoniumbase bestehend. Die Erfindung betrifft eine Kältemischung ; aus salzsauren, salpetersauren und schwefelsauren Salzen der Aikalimetalle und der Ammoniumbase in Mischungen von wechselnder Zusammensetzung. Derartige Kältemischungen, bei denen zur Verflüssigung der Salze das Kristallwasser eines oder mehrerer der gemischten Salze benutzt wird, sind bekannt.Cold mixture, made of hydrochloric, nitric and sulfuric salts consisting of alkalis and ammonium bases. The invention relates to a cold mixture ; from hydrochloric acid, nitric acid and sulfuric acid salts of the alkali metals and the ammonium base in mixtures of varying composition. Such cold mixtures, in which to liquefy the salts the water of crystallization of one or more of the mixed salts are used.

Es wurde gefunden, daß eine besonders rasche und intensive Kältewirkung erzielt werden kann, wenn man die Salzmischung so wählt, daß der Gesamtgehalt an Kristallwasser zwischen 16 und 30 Prozent liegt und zugleich die Salze in einer bestimmten Körnung nicht über 5 mm Körngröße anwendet. Derartige Kälternischungen eignen sich inshesondere zum Beschicken von Kühltromtneln, beispielsweise für Maschinen zur Herstellung von Speiseeis. Nachstehend werden einige Ausführungsbeispiele angeführt. Beispiel I. r g Kaliumchlorid, 3 g Ammoniumnitrat, 26 g Kaliumnitrat, 26 g Ammoniumchlorid, 44 g Natriumsulfat, 9o g Wasser. Beispiel II. 5 g Ammoniumnitrat, 25g Kaliumnitrat, 25 g Ammoniumchlorid, 4.5 g Natriumsulfat, 90 g Wasser. Beispiel III. 5 ä Kaliumchlorid, 26 g Kaliumnitrat, 2.4 g Ammoniumchlorid, .45 g Natriumsulfat, 9o g Wasser. It has been found that a particularly rapid and intense cold effect can be achieved if the salt mixture is chosen so that the total content of crystal water is between 16 and 30 percent and at the same time the salts are used in a certain grain size not exceeding 5 mm. Such cold mixes are particularly suitable for loading cooling drums, for example for machines for making ice cream. Some exemplary embodiments are given below. Example I. rg potassium chloride, 3 g ammonium nitrate, 26 g potassium nitrate, 26 g ammonium chloride, 44 g sodium sulfate, 90 g of water. Example II. 5 g ammonium nitrate, 25g potassium nitrate, 25 g ammonium chloride, 4.5 g sodium sulfate, 90 g of water. Example III. 5 ä potassium chloride, 26 g potassium nitrate, 2.4 g ammonium chloride, .45 g sodium sulfate, 90 g of water.
