Abstract
In making dried animal feed from substantially semi-fluid non-mouldable manure from poultry and other domestic animals the non-mouldable manure is converted into a mouldable product by mixing it with already dried manure and then moulding the product into particles of substantially equal size, which are dried by imparting to the particle a fluidizing movement by means of a flowing hot gas in a so-called fluidized bed. A plant for making dried animal feed from substantially semi-fluid non-mouldable manure from poultry and other domestic animals comprises a mixer with inlets for both the non-mouldable manure and already dried manure, a unit disposed after the mixer for moulding the mixed product into particles, and a container with a perforated bottom in which a fluidizing movement is imparted to the particles in a so-called fluidized bed. The container having the perforated bottom is divided into at least two processing sections following upon each other in the direction of feed of the particles for processing them with separate gases.
