Abstract: The sound wave absorption module (1) comprises a perforated central conduit (20) in which a sound wave is intended to propagate, a casing (10) extending at a distance from and facing the central conduit, in a coaxial manner, an absorption chamber (40) partially delimited by the central conduit and the casing, and a resiliently deformable pocket (30) positioned in the absorption chamber in such a way as to at least partially surround the central conduit, the pocket containing an absorption fluid (31).

Abstract: A continuous grinding device for divided solid material has a chamber extending along a chamber axis, the chamber having an inlet orifice for receiving the material to be processed and an outlet orifice for extracting the processed material, and agitating means for conferring on the chamber an oscillatory translational movement in a plane perpendicular to the chamber axis with respect to a base. The grinding device also has inclining means for adjusting the orientation of the assembly formed by the agitating means and the chamber with respect to the base by way of a pivoting movement about an axis at an angle or perpendicular to the chamber axis. In addition, the device has a ring housed in the chamber and a weight passing through a housing of the ring, an external surface.

Abstract: A continuous system for the heat treatment of divided solids, combined with a gas-solid reaction for the debacterization especially of food products, such as herbs, spices, powders. The system includes a unit for supplying the product a debacterization unit having a fluidized bed moving the particles by means of vibration associated with a feed of steam or other gas, a cooling drying unit, and a packaging unit. The debacterization unit comprises a vibro-fluidized stepped bed for enabling the transport of the product that is carried out successively according to a generally horizontal first transport phase, and at least one second vertical transport phase during which steam or another gas is injected, acting in such a way as to decontaminate the product as it moves from the horizontal phase to the vertical phase and to the following horizontal phase.

Abstract: Heat-treating equipment for roasting food products, including a tub for receiving the product, which is associated with a stirrer and a heat source. The tube includes two vertical, coaxial and hollow cylinders, the inner cylinder defining a first wall, and the outer cylinder defining a second wall of a space having a crown-shaped cross-section, into which the product to be treated is introduced continuously from above for a loading operation that is continuous or in batches. At least one of the two walls in contact with the product is heated and a hot gas is injected into the inner hollow cylinder, so as to make the heat consistent around the product contained within the first crown-shaped space defined by said first and second walls of the tank, between which the stirrer is integrated.
