Abstract: An animal feed production process and apparatus, and pellet product thereby obtained. The process comprises providing a powder composition into a drum, the drum having a disc, a circumferential wall integral with the disc, and an axis of rotation normal to the disc and inclined relative to a vertical axis, the drum being rotatable about said inclined axis and adapted to pass through an upper and lower zones relative to the disc, the powder composition consisting of fine powders of magnesium oxyde, mono-dicalcium phosphate, and at least one substantially insoluble feed ingredient; whereby when the disc is rotated some of the powder composition is carried towards the upper zone, and some of the powder composition tumbles towards the lower zone by gravity; and then spraying water onto the powder composition as the drum is rotated so as to cause the powder composition to agglomerate into pellets of animal feed.

Abstract: The animal food in granular form is essentially spherical and contains a food material, an inorganic food supplement or both and the granules are of generally uniform size between 3 mm and 25 mm. The granules have a moisture content between 5 and 20%, a PDI higher than 90% and a coefficient of variability lower than 10. The granules are prepared by a tumbling process which may include the use of a binder.
