Description

Verfahren zur Entwässerung von Kartoffeln Versuche mit Entwässerungspressen mit Metallsieben haben ergeben, daß die Art der Zerkleinerung von Kartoffeln zur Zellausschließung für den Grad der Trockenheit und den Kraftaufwand von Bedeutung ist, insbesondere bei alten Kartoffeln, die bereits gekeimt haben.Process for dewatering potatoes Experiments with dewatering presses with metal sieves have shown that the type of chopping potatoes for Cell exclusion is important for the degree of dryness and the effort required especially with old potatoes that have already sprouted.

Zerkleinert man Kartoffeln z. B. mit feinen Sägeblattreiben, Mahlwölfen u. dgl., wie dieses z. B. für die Freilegung der Stärkekörner zur Gewinnung der Stärke günstig ist, und preßt man diesen Brei zwecks Entwässerung ab, so wandern die freigelegten Stärkekörner mit dem Fruchtwasser in zu großer Menge gegen die Siebe und verstopfen diese. Haben Kartoffeln gekeimt, so zerstört die Diastase die Stärkekörner, und es entsteht ein Schlamm, der durch die Siebe geht.If you chop potatoes z. B. with fine saw blade grinders, grinding grinders and the like. How this z. B. for the exposure of the starch grains to obtain the Starch is cheap, and if you press this pulp for the purpose of drainage, then wander the exposed starch grains with the amniotic fluid in too large a quantity against the Sieves and clog them. If potatoes have sprouted, the diastase destroys them Starch grains, and a sludge is created that goes through the sieves.

Bildet man dagegen die Zerkleinerungsmaschinen derartig aus, daß man von den Kartoffeln feine Späne und Fäden abzieht, oder schneidet man die Kartoffeln zuerst in feine Scheiben und zerteilt dann diese in Fäden beispielsweise von il/, X I1lz mm, so entsteht durch diesen Vorgang nur eine sehr geringe Freilegung der Stärkekörner. Die Wanderung dieser schadet nicht mehr, weil die Späne und Fäden durch wirre Übereinanderlagerung beim Pressen einen Gewebefilz bilden, der filterartig wirkt. Die intensive Entwässerung erfolgt besser, wenn man diese feinen Späne und Fäden durch enggestellte glatte Walzen schickt, die gegebenenfalls einen ganz geringen Prozentsatz asynchron laufen, um eine Reckung der Genrebe hervorzubringen. Durch diese Manipulation steigt die Wanderung der Stärke nur um ein geringes, doch werden die Zellen geöffnet. Durch Schrägstellen der Walzen kann gleichzeitig eine Vorentwässerung durchgeführt werden. Dieses Pressen (Quetschen) der Fäden mit gleichzeitiger Vorentwässerung kann auch in Schneckenpressen vorgenommen werden, durch die die Stärkewanderung ebenfalls gehemmt wird.On the other hand, if you train the shredding machines in such a way that you pulling fine shavings and threads from the potatoes, or cutting the potatoes first into fine slices and then cut them into threads, for example from il /, X I1lz mm, this process results in only a very slight exposure of the Starch grains. The migration of this does no more harm because of the shavings and threads Form a fabric felt through tangled superimposition during pressing, which is filter-like works. The intensive drainage is better if you have these fine chips and Sends threads through narrow, smooth rollers, which may be very small Percentage run asynchronously to produce a stretch of the genre. By this manipulation increases the migration of strength only by a small amount, but will the cells opened. By tilting the rollers, pre-drainage can be achieved at the same time be performed. This pressing (squeezing) of the threads with simultaneous pre-drainage can also be done in screw presses, through which the starch migration is also inhibited.

PATENTANSPRUCH Verfahren zur Vorbereitung der Entwässerung roher Kartoffeln mittels Schnitzeln, dadurch gekennzeichnet, daß von den Kartoffeln dünne Fäden abgezogen werden; welche in wirrer Anlage einer Walze zugeleitet und so zu einem dünnen Schleier ausgewalzt werden, welcher bei dem nachfolgenden Abpressen in einer Presse sich über- und aneinanderlagernd einen Filz bildet, der beim Pressen eine Stärkeabwanderung verhindert. PATENT CLAIM A method for preparing the drainage of raw potatoes by means of chips, characterized in that thin threads are pulled off the potatoes; which are fed to a roller in a chaotic manner and are thus rolled out into a thin veil, which, during the subsequent pressing in a press, forms a felt layer on top of one another, which prevents starch migration during pressing.
