Eco-friendly and energy-saving barn for animals, e.g. pig

摘要

The invention relates to an environmentally-friendly and energy-saving animal shed, for instance for pigs. The emission of harmful substances such as ammonia from the shed is considerably reduced by intimately mixing ammonia-containing air from the shed with a washing liquid. The moisture content of the manure can herein also be considerably reduced. Circulation means are further disclosed for feeding and draining washing liquid in a circuit to a manure collection space (4) via an aerating device, in addition to activating means for stimulating the activity of bacteria in the degradation process. Further present is a fresh-air supply and heating system wherein heat exchange takes place between fresh and used air, optionally with interposing of washing liquid. The invention finally provides a processing system for manure with which re-usable manure pellets can be made from the produced manure.
