The invention relates to a conditioning/moisturising device for almond grains, especially designed to provide the grains of the fruit with the elasticity required in order to cut the grain into flakes, sticks, cubes or other configurations, with minimum loss through production of flour and others. The device essentially comprises an elongate body, with a generally cylindrical shape and tilted position, which includes on the inside thereof a means for sweeping the almond, made up of a spindle which sweeps the fruit in an upward direction in a steam-saturated environment with controlled temperature, for which purpose the cylindrical body comprises a plurality of steam injection nozzles, said steam being distributed externally and fed to said nozzles from an external steam distributor. The device includes temperature and steam sensors whose measurements are suitable for regulating the rotating speed of the spindle in order to adjust the time during which the almond remains in the environment inside the body.
