A fibrous pulp (2) is used as a papermaking pulp, a component for a packaging or construction material, and is obtained according to a method which comprises a grinding step in which whole annual plant stems (3) are ground to obtain a ground material (4) predominantly containing non-defibrated stem fragments which have a maximum dimension of less than 80 mm. The method also comprises a sorting step in which the ground material is divided into two fractions, fibrous elements which are intertwined together so as to form a homogeneous fibrous mass (5), and particulate residues (6) which are free with respect to the homogeneous fibrous mass, and which are discharged. The method also comprises a thermomechanical treatment step in which the homogeneous fibrous mass is introduced and treated continuously in an extruder (40), at the outlet of which an extrudate forming the fibrous pulp is recovered.
A system comprises a protein-rich and water-rich raw material, a sleeve within which at least one screw is driven so as to subject the raw material to a thermomechanical treatment, and a die. The die comprises a tubular outer casing having a frusto-conical lower face which diverges downstream, this outer casing being fixedly connected to the sleeve such that the material exiting the sleeve is pushed through the die by the screw or screws. The die also comprises an internal member mounted so as to rotate coaxially relative to the casing and including both an upstream part which extends at least partially inside the casing and has a frusto-conical outer face that diverges downstream and a downstream part which extends outside the casing and is coupled to a drive for rotating the member. The casing and/or the upstream part of the member are thermally regulated.
A nozzle includes a tubular, temperature-controlled outer casing, centered on an axis. For a more compact and efficient design, the nozzle also includes an inner member coaxially arranged inside the outer casing and mounted rotatably about the axis relative to the outer casing, such that a downstream portion of the inner member extends outside the outer casing and engages with a drive motor to rotate about the axis, and such that a channel having an annular cross section and centered on the axis is defined between the outer casing and the inner member. The channel has an upstream end and a downstream end between which the material flows into the channel when it is pushed through the nozzle such that, when the material is pushed through the nozzle, the material moves through the channel from the upstream end to the downstream end whereby the material axially exits the channel.

The outer periphery of each tool has radially projecting blades distributed around the central axis, each providing a pinching surface. The pinching surface extends between first and second ends inclined to the central axis. The blades of each tool are distributed following the outer periphery, alternating inclination. When a blade of the first tool is radially interposed between the two tools during the rotation, it is radially aligned with one of the blades of the second tool, the pinching surface inclined in a complementary manner to the pinching surface of first tool's blade, pinching the strand between pinching surfaces of these two aligned blades.
This pinching-shaping device comprises at least one pair of cylindrical tools (100, 200), which each have a central axis (X100, X200) around which the tool is rotated and which are designed so that the central axes are parallel and so that the outer peripheries of the tools are applied tangentially one against the other in order to pinch-shape a strip (2) tangentially introduced between the tools during their rotation. The outer periphery of each tool is provided with radially projecting blades that are successively distributed around the central axis and which each provide a pinching surface. The pinching surface extends between the first end thereof and the second end thereof in a manner inclined with respect to the central axis. In order to obtain novel shapes of products (1) in a simple and economic manner, the blades of each tool are distributed, following the outer periphery of the tool, alternating in inclination such that, each time that one of the blades of a first of the two tools is radially interposed between the two tools during the rotation of the tools, this blade of the first tool is radially aligned with one of the blades of the second tool, the pinching surface of which is inclined in a complementary manner with the pinching surface of this blade of the first tool, in order to pinch the strip between the respective pinching surfaces of these two aligned blades.

Directly at the outlet of the extrusion die (20) and in the axis of the bore (23) for forming the continuous string the device comprises means (30) for directly incorporating at regular intervals said whole solid pieces (2) into the continuous string of food material without altering the initial dimensions thereof.
This food product (100) comprises a filling (102) and a case (104), covering at least the periphery of this filling, this filling being made from pitted dates and having a water activity Aw of less than 0.6.

The invention relates to a method for the continuous production of a powdered product from a product in the liquid state in the form of a solution-, suspension- or emulsion-type mixture in an aqueous medium. According to the invention, during the first step (E1) of the method, the product in the liquid state is transformed into a product in the viscous state. The invention is characterised in that it includes at least one overrun step (E2, E4) and at least one product-drying step (E3, E6) comprising at least a first step (E3) involving thermomechanical treatment with at last one thermomechanical treatment machine into which the viscous state product and a determined amount of powered product from the same family as the liquid state product are injected simultaneously. The treatment machine is configured to mix the viscous state product and the powdered product such as to produce solidified particles of the product upon contact with the ambient air.
The invention relates to a method for the continuous production of an expanded edible food product obtained by cooking-extrusion and containing solid inclusions having a size larger than 0.5 mm.
The present invention relates to a method for producing a powdered porous product from at least one starting powdery and/or viscous product, characterised in that it comprises the continuous following steps without exposing the product to open air: a) preparing the starting product in order to make it viscous; b) in a thermo-mechanical machine (10) for continuously realising transport and/or mixing functions of viscous products or dry-material rich products, lowering the viscosity of the viscous product without changing its dry-material content, by intimate mixing with a gas injected into the processing machine (10) and simultaneously initiating the porosity in the viscous product; c) continuously with the processing machine (10), statically or dynamically intensifying the intimate mixture of the viscous product with a gas in order to obtain an aerated and porous mass; and d), dividing said mass in order to obtain aerated and porous particles.
