The invention relates to a punch support (2) of a compacting machine for producing compacts, said punch support comprising a head (6) to be guided in a cam track (20) of the machine. The invention is characterised in that, for this purpose, the head (6) comprises: a bearing surface (8) that can slide against the cam track (20) and is shaped in such a way as to come into contact with the cam track (20), and a track roller (12) arranged so as to roll on the cam track (20) as the punch support (2) moves through guidance portions of the cam track (20) wherein forces are applied. The invention also comprises a method for using such a punch support and to a compact produced by such a method.

The invention relates to a method for manufacturing a soluble coffee tablet comprising the following successive steps: a. Taking a quantity of a coffee composition comprising coffee, wherein the coffee consists of soluble coffee particles; b. Compaction of the coffee composition to form a compacted coffee product of three-dimensional form; c. Moistening of said compacted coffee product to moisten the exterior surface of the compacted product; d. Drying of the moistened compacted product to form the soluble coffee tablet. Such a method makes it possible to form a soluble coffee tablet having an internal part and an external part entirely surrounding the internal part, with the external part having a greater density than the density of the internal part. The internal part is a porous core promoting the dissolution of the tablet and the external part forms a thick hardened crust with a density greater than the density of the core, thus increasing the mechanical resistance of the tablet.

The invention relates to a method for producing solid milks and to the products obtained with the aid of this method. The method comprises a compression step, then a moistening step, then a drying step. The compression step is carried out with a compaction ratio comprised between 50% and 80%. In the moistening step, water is sprayed on the outside surface of the said compressed and solid milk unit with an amount comprised between 0. mg and 8 mg per cm 2 of the area of the said outside surface, the duration of the moistening step being less than 1 s, to obtain a moistened solid unit having a moistened outside layer of at least two rows of milk particles. The drying step follows the moistening step less than 10 10 s, the duration of the drying step being less than 30 s. The solid milk has a core/crust structure, the average thickness of the crust being at least the thickness of two rows of milk particles.

The invention relates to a press device for making tablets from a mixture of at least one component that includes: a first control means (7) of a first punch, the first control means (7) including a compaction cam (9) for moving the first punch (3) into a compaction position, said compaction cam (9) including a cam path on which said first punch (3) can move, the cam path including a planar portion (90) substantially perpendicular to the axis of the first punch (3), the planar portion (90) extending on an angular section of 5° to 170° for maintaining the first punch (3) in a compaction matrix (2) in a fixed axial compaction position during a predetermined compaction-maintaining duration, a second control means (8) of a second punch, said second control means (8) also including a means for maintaining the second punch in said matrix in a fixed axial compaction position at least during said compaction-maintaining duration in order to maintain the confinement volume, (V) during said compaction-maintaining duration, at a constant volume corresponding to the compaction volume for forming the tablet.

The invention relates to a double-layered compacted solid water-purification product, comprising at least one first layer and at least one second layer, characterised in that the first layer comprises at least one flocculating system and at least one dispersion system, the second layer comprises at least one disinfectant which liberates free chlorine on contact with water and at least one excipient for the disinfectant, whereby said excipient releases the disinfectant into the water at a controlled rate such that the combination of excipient and disinfectant releases 0.1 to 100 mg/l of free chlorine per hour. The invention further relates to the method for production of such a product.
