Abstract
The invention relates to a method for producing granulates which contain enzymes and which are suited for feeding animals. The granulates are produced by mixing at least one enzyme with a supporting material and by extruding this mixture. The inventive method is characterized in that the supporting material is firstly plasticized in a screw mixer which is equipped with at least one horizontally arranged screw. Afterwards, the enzyme is introduced into the screw mixer and is processed with the plasticized supporting material to produce a homogeneous material which is then extruded.
Claims8
A process for producing enzyme-containing granules suitable for animal nutrition, by mixing at least one enzyme with a carrier material and extruding this mixture, which comprises the steps of:
- a) first plasticizing the carrier material in a screw extruder equipped with at least one horizontal screw, and
- b) subsequently introducing the enzyme into the screw extruder and processing it together with the plasticized carrier material to form a homogeneous mixture, and extruding said mixture.
