DE2042514A1 - Pressure-fermented spent beer malts - in mineral feeds and feed concentrates, with unlimited stability - Google Patents

Abstract

Spent beer malt from breweries is fermented during 4 weeks under pressure, to reduce the water-content to =70%. The spent malt is then milled under addition of cattle salt and freed from indigestible parts. After mixing this with other feedstuff components, a stable feedstuff concentrate or mineral feed is obtained. The finished product has unlimited stability and gives practically dust-free feedstuffs.

Description

Production of mineral feed and compound feed (concentrated feed) under Use of spent grains The use of spent grains from the breweries as Feed is known. But so far the use of these spent grains has been in the Delivery form or in already ensiled form as an addition to the usual ones Feed ingredients in mineral or compound feed not possible, namely due to its extremely low shelf life, even in ensiled form was a maximum of 3 days.

Therefore no one had yet tried or considered To use spent grains as an additive to these common feed mixes.

One had to get durable and dust-free mixtures of mineral feed as well as of compound feed or concentrate feed, so far a certain additive related to molasses. However, this material is relatively expensive, as well For mixing with the molasses heated containers, the spraying is required into the mixing device is relatively complicated, especially however, during this mixing, lumps are formed in the mixture, so that these must be crushed again.

Surprisingly, it has now been found that the common spent grains can then be used in mineral and compound feed with an unlimited shelf life, if the spent grains are processed in a certain form and made durable, according to the invention the spent grains preserved in this way has a shelf life of around 1 month and then there is absolute freedom from dust in the mineral and compound feed, if the processed grains are mixed with the other components of the feed is without having to accept the disadvantages of the molasses used so far, which is not available everywhere anyway, as it is only available in areas of the sugar industry accrues. Also the question was still unresolved to what extent the animals did this with the addition Consume mineral feed made from molasses accordingly well.

The invention thus relates to the production of mineral feed and compound feed using spent grains instead of molasses, these being Mixtures have an unlimited shelf life and at the same time are dust-free, and also taste good and smell pleasant when fed.

The method according to the invention for the production of long-life mineral feed and compound feed (concentrate) using spent grains consists in that the spent grains from the breweries are fermented under pressure for approx. 4 weeks, whereby the water content is reduced to a maximum of 70%, based on the weight of the spent grains used is, whereupon the spent grain is crushed with the addition of cattle salt and then by indigestible parts is freed, and that the treated in this way, i.e. after pressure fermentation Chopped and preserved spent grains with the remaining feed ingredients is mixed.

According to the method according to the invention, the water content of the under Pressure fermented spent grains between 65 and 70%, based on the mass of the used Marc, lie.

In the method according to the invention, the proportion of cattle salt is in ensiled, chopped up spent grains mixed with cattle salt at approx. 20%.

The grain size of the fraction of the crushed spent grains in the grains and cattle salt mixture is not more than 1 mm.

The device for carrying out the method according to the invention is characterized in that it consists of a fermentation or silage container with a There is a drain hole at its lower end, preferably below a sieve bottom, and that within the container on the wet spent grains used with usually 80% initial moisture content, an overpressure can be exerted afterwards the fermentation tank a shredding system in the form of a cutting or grinding device, a cutter or the like is arranged, which allows the addition of cattle salt, the spent grains can be crushed to a grain size below 1 mm, and that the device furthermore has a separating device with sieving and collecting, which the excretion of coarse grains, indigestible parts, such as husks or the like, and that this Separating device a mixing device known per se in the form of a mixing drum, a vortex mixer, mixing funnel or the like is nachgeschitet, where the spent grain or the spent grains and cattle salt mixture with the other components of the feed mixture by means of the task is mixed and bagged in the fume cupboard.

According to the device according to the invention, the fermentation or silage container, as well as the downstream shredding - and separation devices mobile.

An embodiment of the method for making durable Mineral feed and compound feed or concentrated feed using spent grains is with reference to the accompanying drawing, in which the device for carrying out the method is shown schematically, explained.

According to Fig. 1, the delivered from the brewery is in a silage container 1 Treber T fermented under the overpressure P, with the water in the fermentation process exits through the sieve bottom 2 from the hole 3.

The spent grains delivered with about 80% moisture has after Fermentation process between 65 and 70% water, based on the mass of the used Marc.

During fermentation, lactic acid is formed in the usual way the pressure fermentation process carried out in this way is at least 1.5%.

During the fermentation process, 1 to 1.5% can be diluted in a known manner Formic acid or a silage salt (Amasil or the like) can be added to the fermentation process to accelerate.

The ensiled spent grain is now according to FIG. 2 in a crushing plant 4 spent, which is indicated in the drawing for example as a cutter C, the material rotating in a trough and laterally by a rotating knife 5 is crushed.

The cattle salt V in proportion is added to the material during the comminution 80% ensiled grains added to 20% salt.

This cattle salt is common unrefined table salt.

Through this addition of salt and its intimate mixing among the Druckvergorenen spent grains is the spent grain, which is produced according to conventional ensiling methods It would be unusable for 1 to 3 days, regardless of whether it left the brewery or the Silo storage comes, preserved for about 4 weeks.

The ones in the cutting or grinding device or the cutter shown C crushed grains and cattle salt mixture has a grain size below 1 mm and is, before it is fed to the mixing plant 8, see Fig. 4, through the separating device, Here the sifter 6, see Fig. 3, is given, where coarser parts and grains are indigestible Components, such as Husks or the like excreted in the collecting device 7 will.

The mixer 8 is the spent grain or the grain / cattle salt mixture TV, in addition, the remaining feed ingredients are supplied by task 9. The mixer can be a mixing drum, a vortex mixer, a mixing hopper 8, or be a similar mixing device that operates continuously or discontinuously.

When the feed mixture is withdrawn from the mixer 8 and in the Trigger 10 is bagged, this has an unlimited shelf life and is located In addition, they are absolutely dust-free.

By the method according to the invention was previously because of his short shelf life only locally usable spent grain is preserved in such a way that it becomes a high quality Storable product as an additive to mixtures of mineral feeds as well as compound feeds or concentrate feed.

Below are two examples of each corresponding mixture listed: Mineral feed (mixture) Dairy cattle feed (compound feed) Composition Composition 42.20% HOSTAPHOS (sodium 45.00% oil meal, and although: magnesium-calcium 15% soy meal, extr.

phosphate) 15% rapeseed meal, extr.

100.00% The proportions in the mineral feed mixes are on average between 8 and 10% spent grains, in compound feed or concentrated feed between 5 and 8 %.

The advantages of adding spent grains according to the invention exist in the following: a) unlimited shelf life and practically dust-free from mineral feed and compound feed, b) cheaper mineral feed, such as compound feed as a result only about half the cost of spent grains compared to molasses, apart from the Freights when using molasses, c) physiologically more valuable because it contains more protein Component in the feed mixes compared to molasses, as well as presence a significant proportion of lactic acid, d) improvement of smell, palatability and digestibility of mineral feeds and compound feeds, resulting in increased yields in agricultural animal husbandry, e) extensive utilization of all that accumulates Brewer's grains with a solution to the problem of spent grains in times of the summer economy of the breweries.
