The invention relates to a method for producing fish meal for direct human consumption that requires an integral processor device comprising a horizontal cylindrical stator having a steam jacket and containing a rotor formed by a central tubular shaft through which steam enters, said rotor being divided into two heating zones, namely a first zone in which the fish meal is cooked and a second zone in which the dehydration operation is performed. The cooking, flavouring and dehydrating process is partially controlled using the steam pressure in the rotor and the gate valve of the product discharge chamber. The operation is easy and allows the evaporation capacity and the percentage of water in the product to be adjusted within the required limits. The device also comprises a gearbox and an electric motor. Flavouring is performed during the entire fish meal production process and the ingredients are fed into the device through metering units located on the upper part of same. The flavouring agents used are natural and provide the fish meal with a flavour that is appealing to the human palate and easy to digest.
