Abstract: The invention concerns a system (10) of a package (2) containing a product and an apparatus (1) using said product, the apparatus being refilled by the product contained in the package, wherein a code (21) related to the contained product is associated to the package, said code being a two dimension code and said code presenting a predetermined surface Scode, and wherein the apparatus comprises a code reader (11) to read the code associated to the package, said code reader being an image capturing device, said image capturing device being defined by: —a predetermined focal range, —a horizontal angle of view ? and a vertical angle of view ?, wherein the apparatus comprises a housing structure (16) and a cavity (12) inside the housing structure, wherein the image capturing device is positioned at the back side of the cavity.

Abstract: The invention concerns process of calibration of a coffee beans roasting apparatus in order to reproduce coffee beans roasting recipes defined with one specific master roasting apparatus, said calibration process comprising the steps of: a—introducing at least one second temporary temperature probe inside the chamber of the roasting apparatus, b—controlling the heating device to reproduce a preset curve R said control being based on the temperature Treg regulated by the at least one first temperature probe, c—during the reproduction of the preset curve Rset, measuring the temperature Tcal in function of time inside the chamber, d—comparing the temperature Tcal@ti with the temperature Tref@ti of a pre-determined calibration curve Rref obtained with the master roasting apparatus (M), said calibration curve Rref representing the temperature Tref measured in the chamber of the specific master apparatus (M) while controlling the heating device of the master apparatus to reproduce said preset curve Rset, e—based on

Abstract: The invention concerns a coffee beans roasting system comprising : - a coffee beans roasting apparatus (10), said apparatus comprising : a chamber (1),. a heating device (2),. at least one first temperature probe (5) to regulate the temperature of air supplied by the heating device, said first temperature probe being positioned outside the chamber,. a control system (80) configured to control the heating device and configured to reproduce roasting curves each of said roasting curves providing a set of points (T@ti; ti) based on the temperature Treg regulated by the at least one first temperature probe, and - at least one second temperature probe (3) configured to be introduced temporary inside the roasting apparatus to measure the temperature inside the roasting chamber, and - means configured to create a pressure loss of the flow of hot air while the chamber is void of coffee beans in order to simulate the presence of coffee beans inside the chamber during a roasting operation.

Abstract: The invention concerns a method for drying at least one cell of the electrostatic precipitator of a smoke treating unit in a system of a coffee beans roasting apparatus and a smoke treating unit, said method comprising the step of passing hot air through said cell, while said cell is positioned inside the electrostatic precipitator and while said cell is switched off.
