Abstract: A method for the production of coffee tablets comprises the steps of: i) providing a uniformly moistened mass of roasted and ground coffee, having a moisture content by weight of between 3 and 11%; ii) feeding the moistened mass to a dosing device; iii) placing a dose of moistened coffee into a cavity of a moulding equipment, the cavity having a bottom surface (35a), a head surface (32a) and a peripheral surface, said the bottom surface (35a), said head surface (32a) and at least a portion (22a) of said peripheral surface being configured to delimit a compression space (CS) of the moistened coffee dose; iv) compressing the dose of moistened coffee (DGC) into the cavity (22) to form a coffee tablet (1); v) removing the coffee tablet (1) from the cavity (22).

Abstract: Cartridge (10) with a filling (12) of at least one substance for preparing a liquid product, said cartridge (10) including a side wall (140), a first end wall (142) through which said liquid product can flow from the cartridge (10) and a second end wall (16) of the cartridge (10) at the opposite side with respect to said first end wall (142), wherein said side wall (140), said first end wall (142) and said second end wall (16) comprise compostable material.

Abstract: A capsule for extraction of a beverage of the filter-coffee type has a capsule body (2), made of water-impermeable material, which defines a chamber (3), present inside which is a precursor of the beverage, comprising soluble coffee and roast and ground coffee. At least 51 wt % of the precursor is roast and ground coffee having a grain size expressed in x50 comprised between 350 and 800 ?m, and the complement to 100 wt % of the precursor is soluble coffee having a grain size expressed in x50 comprised between 1000 and 5000 ?m. The roast and ground coffee is laid out to form a first layer (GC) in the lower part of the capsule body (3), and the soluble coffee (SC) is laid out to form a second layer (SC) in the upper part of the capsule body, i.e., in a position corresponding to the inlet wall (5) and/or above the first layer (GC).
