Feather processing

Feather meal is made from poultry feathers by hydrolyzing under elevated heat and pressure and then drying and grinding. The pressure hydrolysis process is necessary in order to convert the hard, fibrous proteins called keratin, which is the principal component of feathers and hog hair, into feather meal that contains the amino acids.

Hydrolyzation of the feathers, prior to drying, breaks down the protein bonds in the raw material and makes the feather meal more digestible. Hydrolyzed feather meal is a good source of natural protein for most animal diets. It can be used to replace a significant portion of other protein sources in livestock and aquaculture diets.

Available solutions
  • Batch Hydrolyzation

    A simple process with low to medium capacity

  • Continuous indirect hydrolyzation (CFH)

    A continious process with medium to high capacity

  • Continuous direct hydrolyzation (ACH)

    An energy-efficient continuous process with medium to high capacity. Evaporators can be added to increase the yield and improve the feather meal quality.

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.
