Multiformulae extrusion process for industrial manufacturing of sterilized extruded fodders

This project has consisted of the development of a manufacturing process totally automated and programmable by personal computer (PC) based on extrusion methods in order to obtain sterilized food for animals, under working temperature conditions between 115 C and 145 C, and crumb shaped (with no defined shape). The process includes an additional conforming operation, and will therefore never exceed an energy production rate of 30 KW per tonne for pig, chicken, horses and fishes recipes. The objectives achieved up to the current date are the following: All the parameters of the product requirements and also those of the operating process for each production line (chicken, laying hens, baby pigs, porks and horses) have been defined. A totally automated process has been defined, which is prepared for incorporating on line quality and moisture controls. The dust emissions to atmosphere have been reduced. From the last tests, a reduction of a 0.25% has been achieved. Complete sterilization of the product with total elimination of salmonella, a minimum reduction of a 60% of inhibitory digestive and anti-nutritional factors, and with a cooking temperature between 115 C and 145 C. A reduction of the formulation costs between 3 and 8% depending on the grease content and its price. Reduction by about 8% of the manufacturing costs in comparison to the expander and pellet mill system. Starch gelatinisation is increased between 2 and 5% in comparison to the expander and pellet mill system. The conversion rates in farms are improving between 1 and 3% in relation to the above mentioned system.
