Abstract

The system removes husk from grain by subjecting it to the effect of lipuid nitrogen, which causes the husk to peel off at temperatures below minus fifty centigrades. Apart from removing the husk from the grain the process makes the grain inert which has a beneficial effect on the storing qualities and also reduces the danger of explosion due to the fact, that during the under-cooling process nitrogen gas is liberated and protects the grain against explosion.

Description

Beschreibung und Erläuterunq zur PatentanmeldungDescription and explanation of the patent application

'Verfahren zur Trennung von Getreidekornschalen vom Kornkern' Erfindungsgemäß wird vorgeschlagen, das Getreidekorn auf dem Weg zu den Silos bzw. zum Mahl vorgang so zu unterkühlen, dan die Getreidekornschalen vom Kornkern abplatzen und das Korninnere somit freigelegt wird, daß bei einer nrchgeschalteten Sichtung z. B. effektiv nur der Kornkern zur Mahlung freigesetzt ist.'Method for separating cereal grain husks from the kernel' according to the invention it is suggested to process the grain on the way to the silos or to the grinding so to subcool, then the grain husks flake off the grain kernel and the grain inside thus it is revealed that in a nrchgeschaltet sighting z. B. effective only the grain kernel is released for grinding.

Die Gefrierung kann z. B. durch Stickstoff vorgenommen werden (z. B. flüssiger Stickstoff) und bei Temperaturen von z. B. weit unter -50 OC durchgeführt werden.The freezing can e.g. B. be made by nitrogen (e.g. B. liquid nitrogen) and at temperatures of z. B. carried out well below -50 OC will.

Hierdurch wird weiterhin erreicht, daß ein Inertisierungsprozeß gleichzeitig erzielt wird, da der Stickstoff als Inertgas bei der Lagerung und/oder Mahlung zur Verfüqung steht.This also ensures that an inerting process is carried out at the same time is achieved because the nitrogen is used as an inert gas during storage and / or grinding Available.

Durch diese erfindungsgemäße Verfahrensweise wird a) eine wesentliche Mahl arbeit erspart und b) die Explosionsgefahr ausgeschlossen.This procedure according to the invention makes a) an essential one Saves grinding work and b) eliminates the risk of explosion.

Selbstverständlich ist die Erfindunq nicht auf den obi9 beschriebenen Ablauf beschränkt, sondern es sind zahlreiche Abänderunaen möglich, ohne jedoch von dem Grundgedanken abzuweichen, das Korn vor der Mahlung stark zu unterkühlen, um den Kornkern freizuleqen und mit dem freigesetzten Inertgas die Lagerung und/oder den Mahl prozeß ohne Explosionsqefahr durchführen zu können.Of course, the invention is not described on the obi9 The process is limited, but numerous changes are possible without, however to deviate from the basic idea of strongly supercooling the grain before grinding, to free the grain core and with the released inert gas the storage and / or to be able to carry out the grinding process without the risk of explosion.
