Description
Verfahren zur Herstellung eines kaltquellenden Stärkemehles Die Erfindung betriffst ein Verfahren zur Her stellung eines kaltquellenden Stärkemehles, das sich insbesondere zur kochfreien Bereitung von Pudding speisen eignet.
Es ist seit langem bekannt, dass man zu diesem Zweck die Stärke, z. B. Kartoffel- oder Maisstärke, mit Wasser zu einer Suspension ansetzt, diese ver kleistert und sie dann in ein Trockenprodukt über- führt.
Während die Sprühtrocknung sich für diesen Zweck nicht bewährt, vor allem, weil sie zu teuer wird, hat die Walzentrocknung bisher den grossen Nachteil, dass kein sehr homogenes Erzeugnis ent steht. Selbst wenn man das Trockengut stark zer mahlt, ist der daraus hergestellte Kaltpudding bei der Verkostung griessartig körnig, also nicht so glatt und amorph wie ein Kochpudding.
Die Untersuchungen der Anmelderin haben ge zeigt, dass dies auf die beim Trocknen oft auftretenden Verhornungen zurückzuführen ist. Auch wenn man auf der Walze ganz dünnschichtig trocknet, lässt sich nicht verhüten, dass die verkleisterte Stärke bei den für einen ausreichenden Feuchtigkeitsentzug erforder- lichen Temperaturen Partikelchen mit besonders fester Aussenhaut bildet.
Die Erfindung hat ein Verfahren zum Gegenstand, das diesen Nachteil voll beseitigt und zu einem Pro dukt führt, welches besonders hohe Feinheit und Gleichmässigkeit aufweist. Man erreicht dies da durch, dass die Stärkesuspension dem Trockner in einer schaumig-mayonnaisenartigen Konsistenz zu- geführt wird.
Die Stärkesuspension wird zweckmässig mit Luft vermischt, so .dass die Trockensubstanz des Ansatzes schon z. B. der Trocknungswalze in feinster Ver teilung zugeführt wird, derart, dass auf der Walze eine Art Zerstäubungstrocknung stattfindet. Für die Luftzufuhr bieten sich verschiedene Mög lichkeiten. Man könnte Luft beispielsweise in die Suspension direkt einblasen.
Zweckmässig ist es aller- dings, die Suspension einem Rühr- oder Schlagvor gang zu unterwerfen. In der Praxis hat es sich hierbei besonders bewährt, die Suspension durch eine Kolloid- mühle zu schicken.
Während für den Regelfahl d ie Verwendung eines Walzentrockners für die erfindungsgemässen Zwecke das Gegebene ist, wäre es natürlich auch angängig, andere Trocknungsvorrichtungen, z. B, Heizplatten oder dergleichen, zu verwenden.
<I>Beispiel</I> Auf einem 2-Walzentrockner, welcher mit 4 Um drehungen pro Minute und mit 4,5 Atü Dampf ent- sprechend l55 C betrieben wird, wird eine 25 % ige Stärkesuspension getrocknet,
wobei die Stärke wahl weise in Wasser oder in einem Gemisch aus Wasser und Magermilch suspendiert sein kann. Dia Suspen sion 'wird zuvor mittels einer Kolloidmühle zu einer schaumigen, stark lufthaltigen, aber noch fliessbaren Masse verarbeitet. Der Suspension können auch Farbstoffe, Aromastoffe und dergleichen zugesetzt werden.
Während in diesem Falle die Verkleisterung der Stärke in dem Sumpf erfolgt; aus dem die Trock- nungswalze das Arbeitsgut aufnimmt, wäre es natür lich auch möglich, die Verkleisterung vorher vor- zunehmen.
Method for producing a cold-swelling starch flour The invention relates to a method for producing a cold-swelling starch flour, which is particularly suitable for cooking pudding without cooking.
It has long been known that strength, e.g. B. potato or corn starch, is mixed with water to form a suspension, pastes it and then converts it into a dry product.
While spray drying has not proven itself for this purpose, mainly because it is too expensive, roller drying has hitherto had the major disadvantage that it does not produce a very homogeneous product. Even if you grind the dry food heavily, the cold pudding made from it is gritty-like when tasted, i.e. not as smooth and amorphous as a cooked pudding.
The applicant's investigations have shown that this is due to the keratinization that often occurs during drying. Even if you dry very thin layers on the roller, you cannot prevent the gelatinized starch from forming particles with a particularly firm outer skin at the temperatures required for sufficient moisture removal.
The subject of the invention is a method which completely eliminates this disadvantage and leads to a product which is particularly fine and uniform. This is achieved by feeding the starch suspension to the dryer in a foamy, mayonnaise-like consistency.
The starch suspension is expediently mixed with air, so that the dry substance of the batch is already z. B. the drying roller is supplied in the finest distribution Ver, such that a type of spray drying takes place on the roller. There are various possibilities for the air supply. For example, air could be blown directly into the suspension.
It is advisable, however, to subject the suspension to a stirring or beating process. In practice, it has proven particularly useful to send the suspension through a colloid mill.
While for the rule the use of a drum dryer for the purposes of the invention is given, it would of course also be possible to use other drying devices, e.g. B, heating plates or the like to be used.
<I> Example </I> A 25% starch suspension is dried on a 2-drum dryer, which is operated at 4 revolutions per minute and with 4.5 atmospheres of steam corresponding to 155 C,
wherein the starch can optionally be suspended in water or in a mixture of water and skimmed milk. The suspension is processed beforehand using a colloid mill into a foamy, highly aerated, but still flowable mass. Colorings, flavorings and the like can also be added to the suspension.
While in this case the starch is gelatinized in the sump; From which the drying roller picks up the work, it would of course also be possible to perform the gelatinization beforehand.
