Blood Processing System

Blood Processing System

The Rendertech Blood Processing System (BPS) is a continuous process for converting animal blood into a high-quality blood meal. The process is efficient, economical, and simple to operate, with the key piece of process equipment being the steam-heated Rendertech Contact Drier (CD).

  • A continuous, automated system that is simple to operate and maintain.
  • Lower energy requirements – the blood is steam-coagulated and then mechanically separated.
  • Compact design.
  • Produces high-quality blood meal with low environmental impact.
  • The enclosed system captures odours and dust.


Raw blood is continuously pumped from the Storage Tank through the inline Coagulator, where the protein is coagulated by steam injection. After coagulation it flows to the Decanter.

Mechanical dewatering
In the Decanter, centrifugal force separates the water from the coagulum. The blood water is discharged for further processing and the coagulum – containing 55–60% moisture – is conveyed to the Contact Drier.

The coagulum is continuously fed to the Contact Drier (CD), where it is heated and the moisture evaporated through contact with steam-heated discs. The CD is fitted with a scrubber to recover fine blood dust from the vapour stream back into the product. The resulting dried meal is continuously discharged using the discharge screw conveyor.

The dried blood meal is milled by a Hammermill. The integral fan blows the milled meal into the meal bagging bin.

Ancillary equipment
