Abstract: The Invention relates to a process for the milling of vegetable-based material, in particular plants like seeds, to produce dehulled or/and fractionate flour that includes a Material Bed Compression milling of the vegetable-based material. A first air classification of the milled material is performed to obtain a first fine fraction on one side and a first coarse fraction on the other side. A first post-treatment to the first fine fraction is then performed to obtain separate flour. The first coarse fraction is then recycled to the milling step.

Abstract: A method for continuous aeraulic separation of particulate materials consisting of a mixture of particles that is heterogeneous in both particle size and density is provided. The method includes grinding particles of materials, generating a gas stream conveying the ground particles, first aeraulic separation on the gas stream in order to separate the particles it contains into a first fraction consisting of the coarsest particles with variable densities and a second fraction consisting of the finest particles. A second aeraulic separation is performed on the first fraction in order to separate the particles that it contains into a third fraction consisting of the coarsest and/or most dense particles and a fourth fraction consisting of the least coarse and/or the least dense particles.
