A Novel Research on Drying Process for Breeding Stock Blood Zhang Zhongjie Luan Zhaokun (Research Center for Eco-Environmental Sciences Chinese Academy of Sciences Beijing 100085, China) ABSTRACT:Breeding stock fresh blood is nutritious for its rich in protein. According to the physical chemistry characteristics of blood, a novel method was developed to dry blood by combining the technique such as membrane separation, high pressure spray drying and extrusion & expanding through a number of experiments. The experiment results show that the method can decrease the evaporation energy consumption more than 40 percent during the process and good plasma protein obtained after industrialization, the digestibility was also improved much more than before.
