te 234736 CLASS 6 b. GROUP. 1,

HANS DESCHERMAYR in STRAUBING, N.-B.

There are devices for cleaning grain known in which this in a trough filled with water and provided with various subdivisions. The heavy parts adhering to the grain settle in one compartment, such as Sand, earth, etc., while the lighter grains are carried away into the other compartment.

ίο This device cannot be used for malt, because there is intensive washing in it, which is harmful to the malt, and because it also provides the desired sorting of the malt does not allow.

The present invention now relates to a method for sorting and cleaning finished dried malt in such a way that the specifically heaviest part, the so-called stone malt, the specifically lighter types of malt and the specifically lightest part, the good malt, can be obtained separately from each other and at the same time an improvement in quality is achieved will.

This is achieved by pouring the malt to be sorted into one of water 0. flowed through container, which with in the direction of flow in height, increasing, possibly sieve-like partition walls is provided, is passed, such that the malt according to the specific gravity in different grades is separated by the specific heaviest, the so-called stone malt first, the specifically lighter types of malt later sink while the light, good malt settles at or near the surface of the water moved and drains from the water tank into special containers. In these will the malt is then centrifuged and immediately put in dryers with up to ι to 2 percent water content dried, as is the case when washing malt in such a way that only its husks are soaked in water, is already known.

In the drawing, a device used to carry out the method is shown in FIG. 1 in longitudinal direction and in FIG. 2 in cross section along line AB of FIG.

The container α is divided into chambers c, d, e, f etc. of suitable size by sieve-like partitions b, the height of which increases from the malt supply to the discharge side. The chamber bottoms are provided with openings which are closed by lids h o. The like., And allow removal of the deposited in the individual chambers malt varieties.

The supply of the malt to the container a takes place through a divided gutter i above the first compartment of the container. The water is fed to the same compartment through a perforated pipe k, the bores of which extend backwards towards the gutter i.

The drainage of the malt floating on or near the surface and the excess water takes place at the other end of the container α through a channel I , which discharges malt and water into a mobile centrifugal drum m. In this the malt is largely freed of water, so that it is now on suitable drying devices, which expediently with exhaust steam

are heated up to ι to 2 percent water content can be dried.

In order to make the light malt floating on the water surface completely dust-free if it is not sufficiently wet when it falls into the container α and is thus freed from dust and the like, a beater or the like immersion device η is provided, which is provided by a transmission is suitably driven.

The mode of operation of the device is as follows: The malt introduced into the container a from the gutter i is first moistened by the jets of water emerging from the openings of the pipe k and pressed down into the water-filled container. Here, that part of the malt which has the greatest specific gravity falls directly to the bottom and is collected in the container chamber c , while the types of malt with a lower specific gravity are carried away by the flow maintained in the container α and a greater or equal to their weight Cover a shorter path at a greater or lesser height in the container α until they sink to the floor between the partitions b and are thus excreted in chambers. The malt with the lowest specific weight rises immediately behind the water supply pipe k to the surface of the water and is pressed again under the surface of the water by the immersion device η on the way to the other end of the container, making it completely free of dust.

This part of the malt, which consists of well-dissolved grains, due to this property is lighter than the rest of the malt and therefore requires the lowest tax amount, now emerges with the excess water from the container α through the channel I and becomes a centrifugal drum · M transferred , in which it is mechanically freed from the adhering water by centrifugal action and then dried in drying devices with a water content of up to 1 to 2 percent.

The less well dissolved part of the malt is also caused by the moistening and subsequent drying improved for immediate processing.

Several centrifugal drums are used to enable continuous operation and made mobile so that every drum filled with malt is immediately replaced by an empty one can be.

It should also be mentioned that the size and subdivision of the container α can be selected differently according to the types of malt to be produced. 60 ■

Of course, the types of malt that are initially deposited lying on the outlet of the container α can continue to be used as required and possibly mixed with the light malt.

It should also be noted that the treatment of the malt according to the present method should take place no more than one day before the simmering or further processing.

Claims (1)

Patent CLAIM: Process for sorting and cleaning all types of dried malt, characterized in that the malt in one of water o. The like. Flowed through Container that increases in height in the direction of flow, possibly sieve-like formed partitions is provided, is passed, such that the malt according to the specific gravity in different Varieties are separated by having the specifically heaviest, the so-called stone malt, first, the specifically lighter types of malt only sink later, while the specifically lightest malt, the good malt, swims at or near the surface and is collected or centrifuged in a special container and then dried in a known manner. 1 sheet of drawings.
