Method for preparing a dry dairy product in solid form comprising fat at a content comprised between 0% and 40% by weight relative to the total weight of said dry dairy product in solid form, having a density comprised between 0.5g/cm 3 to 2g/cm 3 and not containing lubricants, sliding agents, wetting agents, emulsifying agents, or disintegrating agents comprising the following steps: a. preparing a milk particles powder comprising lactose for compression at a content comprised between 5 and 40% by weight relative to the total weight of said dry dairy product in solid form, this lactose for compression being present in addition to the lactose possibly already present in the milk particles powder and, optionally, ingredients of nutritional interest; the lactose for compression being added in a final dry mixing step and is chosen from among granulated α-monohydrate lactose comprising a percentage of amorphous lactose less than 10% by weight of which the final grain size (median diameter) is comprised between 80 and 250μm, the Spray Dry α-monohydrate lactose comprising a percentage of amorphous lactose less than 15% by weight of which the final grain size (median diameter) is comprised between 80 and 250μm, the β-anhydrous lactose comprising a percentage of amorphous lactose less than 5% by weight of which the final grain size (median diameter) is comprised between 80 and 250μm, and the amorphous lactose of which the final grain size (median diameter) is comprised between 80 and 250μm; b. granulation of the milk particles powder according to one of the two methods below: b1. wet granulation: wetting of the mixture obtained in step a) by addition of a water content comprised between 1% and 15% by weight relative to the total weight of the milk particles powder; granulation of said mixture; and drying of the wet powder of granulates of said mixture under hot air between 40°C and 80°C to obtain a residual free humidity less than 3% by weight; b2. dry granulation of the mixture obtained in step a); c. sifting of the powder of dried granulates obtained in step b) between 250μm and 2mm; d. densifying of the powder of dried granulates obtained in step c) and put in solid form to obtain the dry dairy product in solid form, the compression force applied is comprised between 5 and 30kN. a. preparing a milk particles powder comprising lactose for compression at a content comprised between 5 and 40% by weight relative to the total weight of said dry dairy product in solid form, this lactose for compression being present in addition to the lactose possibly already present in the milk particles powder and, optionally, ingredients of nutritional interest; the lactose for compression being added in a final dry mixing step and is chosen from among granulated α-monohydrate lactose comprising a percentage of amorphous lactose less than 10% by weight of which the final grain size (median diameter) is comprised between 80 and 250μm, the Spray Dry α-monohydrate lactose comprising a percentage of amorphous lactose less than 15% by weight of which the final grain size (median diameter) is comprised between 80 and 250μm, the β-anhydrous lactose comprising a percentage of amorphous lactose less than 5% by weight of which the final grain size (median diameter) is comprised between 80 and 250μm, and the amorphous lactose of which the final grain size (median diameter) is comprised between 80 and 250μm; b. granulation of the milk particles powder according to one of the two methods below: b1. wet granulation: wetting of the mixture obtained in step a) by addition of a water content comprised between 1% and 15% by weight relative to the total weight of the milk particles powder; granulation of said mixture; and drying of the wet powder of granulates of said mixture under hot air between 40°C and 80°C to obtain a residual free humidity less than 3% by weight; b2. dry granulation of the mixture obtained in step a); b1. wet granulation: wetting of the mixture obtained in step a) by addition of a water content comprised between 1% and 15% by weight relative to the total weight of the milk particles powder; granulation of said mixture; and drying of the wet powder of granulates of said mixture under hot air between 40°C and 80°C to obtain a residual free humidity less than 3% by weight; b2. dry granulation of the mixture obtained in step a); c. sifting of the powder of dried granulates obtained in step b) between 250μm and 2mm; d. densifying of the powder of dried granulates obtained in step c) and put in solid form to obtain the dry dairy product in solid form, the compression force applied is comprised between 5 and 30kN.
