Description

Wasserbad zur Pasteurisierung oder Sterilisierung von in Glas-oder Metallgefäßen wasserdicht verpackten Lebens- oder Arzneimitteln Zusatz zur Patentanmeldung B 44247 IV, &/ 53 c (Auslegeschrift 1059 753) Gegenstand der Patentanmeldung B 44247 IV a / 53 c ist die Verwendung von Orthophosphate enthaltenden wäßrigen Lösungen als Wasserbäder, die der Pasteurisierung und/oder Sterilisierung von Konservendosen oder Behältnissen aus Blech, Kunststoffgefäßen, Einweckgläsern u. dgl. bei mehr oder minder höheren Temperaturen dienen. Wesentlich dabei ist, daß in dem Wasserbad ein pH-Wert zwischen 6 und 9 eingehalten wird und für den Fall, daß Orthophosphat nicht allein, sondern im Gemisch mit anderen Stoffen zugesetzt wird, der P205 Gehalt, berechnet auf die Trockensubstanz der Wasserbadzusätze, mindestens 10% beträgt. Ein entscheidender Fortschritt dieses Verfahrens ist, daß alle bisher üblichen Vor- und/oder Nachbehandlungen des Gutes mit Reinigungsmitteln nach dem neuen Verfahren entfallen können.Water bath for pasteurizing or sterilizing in glass or metal containers packaged food or drugs waterproof addition to the patent application B 44247 IV, & / 53 c (Auslegeschrift 1 059 7 53) subject of the patent application B 44247 IV a / c is 53, the use of orthophosphate containing aqueous solutions as water baths, which are used for pasteurization and / or sterilization of tin cans or containers made of sheet metal, plastic vessels, mason jars and the like at more or less higher temperatures. It is essential that a pH value between 6 and 9 is maintained in the water bath and, in the event that orthophosphate is not added alone but in a mixture with other substances, the P205 content, calculated on the dry substance of the water bath additives, at least 10 % amounts to. A decisive advance in this process is that all previously customary pre- and / or post-treatment of the goods with cleaning agents can be dispensed with according to the new process.

Es wurde nun gefunden, daß an Stelle eines Teils der Orthophosphate auch Citronensäure und/oder Weinsäure bzw. deren Salze als Zusatz zum Wasserbad gegeben werden können. Außerdem können auch Teile der Orthophosphatzusätze durch kondensierte Phosphate, insbesondere Natriumtripolyphosphat, ersetzt werden. Dies bringt insbesondere dann einen Vorteil, wenn, das Behandlungsgut aus leicht korrodierbarem Material, wie z. B. Aluminium, verzinktem Schwarzblech u. dgl., besteht oder wenn infolge der Zusammensetzung des verwendeten Wassers große Mengen der Mischungen gemäß Patentanmeldung B 44247 IV a/ 53 c eingesetzt werden. müssen.It has now been found that instead of part of the orthophosphates also citric acid and / or tartaric acid or their salts as an additive to the water bath can be given. In addition, parts of the orthophosphate additives can also through condensed phosphates, especially sodium tripolyphosphate, are replaced. this brings an advantage in particular when the item to be treated is made of easily corrodible Material such as B. aluminum, galvanized black plate and the like., Is or if large amounts of the mixtures due to the composition of the water used can be used according to patent application B 44247 IV a / 53 c. have to.

Beispiel 1 Ein mit Obstkonserven beschickter Standautoklav wird mit Wasser einer Gesamthärte von 15° gefüllt. Pro m3 Wasser werden 375g einer Mischung, bestehend aus 60% Dinatriumphosphat wasserfrei und 40% Citronensäure, zugegeben. Die nach der Hitzebehandlung aus dem Autoklav kommenden Obstkonserven sind blank und nicht angegriffen. Ohne Zusatz verlassen die Konserven den Autoklav mit starken Kalkflecken und Schleiern.Example 1 A standing autoclave charged with canned fruit is used with Filled with water with a total hardness of 15 °. 375g of a mixture are required per m3 of water, consisting of 60% disodium phosphate anhydrous and 40% citric acid, added. The canned fruit coming out of the autoclave after the heat treatment are bare and not attacked. Without additives, the canned food leaves the autoclave with strong Limescale and haze.

Beispiel 2 Ein Autoklav wird auf 120° C gebracht. Das Füllgut besteht aus Gulaschkonserven, die in Weißblechdosen verpackt sind. Ohne Zusatzmittel verlassen die Konserven bei einer Betriebswasserhärte von 18'' Gesamthärte den. Au,toklav mit einem schneeweißen Überzug, der noch zum großen Teil Gulasch.- und Soßenreste enthält. Durch Zusatz einer Mischung, b,&-stehend aus 40°/o Dinatriumphosphat, 22'0/a Trinatriurnphosphat, 6,75'% Tripodyphosphat, 6,750/0 Soda, 24,51/o Weinsäure, in Mengen von 250 g/m3 verlassen die Büchsen in, sauberem, fettfreiem Zustand den Autoklav. Korrosionsangriffe, die sich im Anfangs-Stadium als Anlauffarben zeigen, werden verhindert.Example 2 An autoclave is brought to 120 ° C. The filling consists of canned goulash, which are packed in tin cans. Without additives, the canned food leaves the system with a total hardness of 18 ''. Au, toklav with a snow-white coating, which still largely contains goulash and sauce leftovers. By adding a mixture consisting of 40% disodium phosphate, 22% trinatrium phosphate, 6.75% tripodyphosphate, 6.750% soda, 24.51% tartaric acid, in quantities of 250 g / m3 the cans leave the autoclave in a clean, grease-free condition. Corrosion attacks, which show up as tarnishing in the initial stage, are prevented.
