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