ensiling of brewery stillage

Brewery stillage is a waste created during the beer production process. Its composition includes barley malt, barley and wheat, which makes it a valuable feed used in feed of both cattle and pigs. For the dairy cattle it is a lactogenic feed, rich in proteins and energy. Its protein is characterized by moderate susceptibility to dissolution in the rumen, thanks to which a lot of that protein moves to the small intestine and is digested to amino acids there. The stillage is a good component of a total mixed ration, since thanks to its “juicy” structure it limits the sorting of feeds by the cows.

The fresh stillage contains a lot of water, protein and fermentation ingredients and therefore it is a very non-durable feed that is also very hard to ensilage. Without ensiling it can be stored in the temperature of 5 Celsius degrees for not more than two days. The fastest and the most efficient method of stillage ensiling is a silo bag. Ensiling in a silo bag ensures immediate separation from oxygen and facilitates lactic acid fermentation. The stillage in a silo bag can be stored for a long time without the risk that the material will spoil. When ensiling the stillage in drive-through silos or heaps it is hard to compact and cover the silage quickly. Therefore the quality of the ensilaged material can be low and losses may amount up to 30 percent.

The additional advantage of ensiling in a silo bag is that the stillage can be purchased and stored during summer, when its availability is the highest.

We provide the stillage packing services with the use of Agripak packers on the whole territory of Poland. The machines can be fitted with tunnels having the diameter of 1.95 m, 2.4 m or 2.7 m and the capacity from 110 to 270 tons. The stillage can be loaded into the machine by means of a telescopic loader or a front end loader. The packers can be fitted with ensiling product applicators.
