<p>A method and a machine for continuous coating of cores of products, in particular confectionery products, in which a hollow drum rotating about an axis of its own carries, stably connected inside it, a body wound axially in a helix or a spiral, with which it delimits a plurality of treatment chambers, each adapted to house a mass of cores to be treated; in at least part of the chambers, the mass of cores is sprayed with a coating material during rotation of the drum in a first direction of rotation about its axis, and impinged upon by a flow of process air during rotation of the drum in a second direction of rotation opposite to the first direction of rotation, before feeding the coated cores into an adjacent chamber causing the drum to perform a complete rotation in one of the two directions of rotation.</p> |
