Blood Processing

Blood contains 16 to 18 percent protein solids and dried blood meal is a valuable ingredient in feed for non-ruminant animals because it has a high lysine content. Blood meal is also used as a high-nitrogen fertilizer.

The blood is fed into a blood coagulator in which the blood coagulates. The coagulated blood solids and water are separated in a decanter and the blood solids are dried in either a Continuous Cooker or a Batch Cooker.

This method is very energy efficient, because about more than half of the water is removed mechanically before drying.
