The method for producing solid milks according to the invention comprises the following steps: compressing milk powder at a compression speed between 110 and 200 mm/s to obtain a solid unit, moistening the solid unit by spraying an amount of water between 0.1 and 8 mg/cm2, then drying the solid unit.

Abstract: The invention relates to a method for producing solid milks and to the products obtained therefrom. The method comprises a compression step, a moistening step, and a drying step. The compression step is carried out with a compaction ratio between 50% and 80%. In the moistening step, water is sprayed for less than 1 s onto the compressed milk unit in an amount between 0.1 mg and 8 mg per cm2 of the outside surface area. The drying step follows the moistening step for less than 10 s, the duration of the drying step being less than 30 s. The solid milk has a core/crust structure, the average thickness of the crust being at least the thickness of two rows of milk particles.
