  • Method for manufacturing feed pellets and a plant for use in the implementation of the method
    Patent number: 7001636
    Abstract: A method for manufacturing feed pellets, and a plant for the implementation of this method have been explained. The aim has been to improve the manufacturing of porous pellets, first and foremost to achieve a better control of the porosity of the pellets than the known techniques. The pellets come from a pelletizing machine (1) into a pellet chamber (3) which is kept at a pressure lower than the ambient pressure. From the chamber (3) the pellets are passed through an outlet (5) having a gate lock body (6).

  • Feed mass having a modified protein structure for carnivorous animals
    Patent number: 6528100
    Abstract: A method for producing feed for forming into pellets, the pellets produced by the method to be used to feed carnivorous animals. The addition of the enzyme transglutaminase to a feed mass specifically intended for carnivorous fish will catalyze a reaction between the amino acids glutamine and lysine which form part of the protein chains and the raw material of the proteins of the feed, such that a covalent chemical bond is formed between them, which results in shape permanence in the formed, dried, finished pellets, such that the finished pellets do not lose their shape before time of use.
