Compound feed


As different as the various mixes and variations may be, in principle the production of compound feed always follows the same principle: First, the raw materials stored are weighed and dosed. After milling with hammer mills, they are mixed following different recipes and often blended with odour-intensive substances, such as fats. The consequence: odour emissions that can harm the environment are released. In addition, milling of fine, dry ingredients produces dust. Additional dust emissions are released through pelletizing. It’s no wonder that regulations regarding dust and odour emissions have intensified over time: Production volumes increase and residential areas are spreading closer and closer to production sites. To meet the strict limits in production, we put dust and odour emissions in their place: With our COPLAS clean technology, we offer a modular system for the treatment of the exhaust air of multiple production lines – individually or together. For the sustainable production of compound feed, we do not use water or chemicals and no waste products of any kind are accrued.
