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).
A continuous grinding device for divided solid material has a chamber (2) extending along a chamber (2) axis, the chamber (2) having an inlet orifice (24) for receiving the material to be processed and an outlet orifice (25) for extracting the processed material, and agitating means (3) for conferring on the chamber (2) an oscillatory translational movement in a plane perpendicular to the chamber axis (A) with respect to a base (1). The grinding device also has inclining means (4) for adjusting the orientation of the assembly formed by the agitating means (3) and the chamber (2) with respect to the base (1) by way of a pivoting movement about an axis at an angle or perpendicular to the chamber axis (A). In addition, the device has a ring (8) housed in the chamber (2) and a weight (9) passing through a housing (81) of the ring (8), an external surface of the ring (8) and the housing (81) having one and the same axis of revolution.

HEAT-TREATING EQUIPMENT, IN PARTICULAR FOR ROASTING FOOD PRODUCTS
The present invention relates to heat-treating equipment (1), in particular for roasting food products, including a tub (2) for receiving the product, which is associated with a stirring means (4) and a heat source (5), characterized in that the tub (2) consists of two vertical, coaxial and hollow cylinders (6, 7), the inner cylinder (6) defining a first wall (8), and the outer cylinder (7) defining a second wall (9) of a space (10) having a crown-shaped cross-section, into which the product (3) 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 (8, 9) in contact with the product (3) being heated (5) by conductivity via electric resistors or a heat transfer fluid, a hot gas (5) also being injected into the inner hollow cylinder (6), so as to make the heat consistent (5) around the product (3) contained within the first crown-shaped space (10) defined by said first and second walls (8, 9) of the tank (2), between which the stirring means (4) are integrated.
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.

CONTINUOUS TREATMENT SYSTEM FOR THE DEBACTERISATION OF DIVIDED SOLIDS, ESPECIALLY FOOD PRODUCTS
The invention relates to a continuous system for the heat treatment of divided solids, combined with a gas-solid reaction for the debacterisation especially of food products, such as herbs, spices, powders etc., said system being of the type consisting of: a unit (2) for supplying the product; a debacterisation unit (3) consisting of a fluidised bed moving the particules by means of vibration, associated with a feed of steam or other gas; a cooling drying unit; and a packaging unit (4). Said system is characterised in that the debacterisation unit (3) comprises a vibro-fluidised stepped bed (5) for enabling the transport of the product (6) that is carried out successively according to a generally horizontal first transport phase (h), and at least one second vertical transport phase (V) 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 (H) to the vertical phase (V) and to the following horizontal phase (H).
