Abstract

This paper reports about a technology solution for recovering blood products coming from meat industries. Blood products comprise raw blood coming from slaughtered animals as well as all kind of derived products like plasma, red blood cells, etc. The technology we claim revaluates blood products by means of their transformation into blood meal, and is protected under two USC patents. Blood coming from meat industries constitutes a highly hazardous waste. Mismanagement could cause environmental risks and microbiological growth responsible for public health concerns. Accordingly, meat industries devote great efforts to managing blood from their facilities as a waste. The most widely used solution is narrowed to hiring a waste manager, which implies additional costs. Despite the advantages, blood contains vast amounts of high added value chemical components, such as lysine, an essential amino acid for many farm animals and pets. One way of turning blood into an innocuous product that contains all of its high value components consists of transforming it into blood meal. The reported technology converts blood products into meal making use of low temperature dewatering processes, which assures a high quality dried product. It comprises a vacuum multiple effect evaporation system with scraped surface heat exchangers that prevent the undesirable phenomenon of blood coagulation.
