Abstract: A method for manufacturing intermediate products for preparation of animal feeds comprising the steps of: (a) heating a crude granular raw material in a vessel containing a heating device at a temperature sufficient to toast the raw material; (b) feeding the toasted crude raw material from the vessel to a container; (c) cooling the toasted raw material within the container by contacting the toasted raw material with cold air in counterflow to the feeding of the toasted raw material in order to heat and moisten the cold air and to cool and dry the raw material so as to obtain the intermediate products; and (d) feeding the heated moist air back to the vessel thereby recovering the energy from the heating step (a).
