A method of making a tablet for hot espresso beverage extraction, comprising the steps of a) grinding a brewable product to obtain a powder having a substantially uniform particle size, b) dosing a predetermined amount of the ground product powder, c) moistening the powdered product dose, d) homogenizing the moistened mixture to obtain a powdered product with a substantially uniform moisture content, e) forming the powdered product dose by compression to obtain a disk-shaped or prismatic tablet (C), supplying an amount of energy to the tablet (C) to obtain a substantially compact and integral item. The step f) of supplying energy is carried out at a distance by irradiating g) the tablet (C) with an electromagnetic wave beam (F) to overheat and partially bake and/or sinter the particles of the powdered product as well as to impart a relatively compact and self-supporting construction to the finished tablet (C). The electromagnetic wave irradiation step g) is carried out at the end of the forming step e) while continuously compressing the dose. |
