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 this comparison, calibrating the roasting apparatus by applying a correction, to the temperature Treg regulated by the first temperature probe inside the control system of the roasting apparatus.

Process of calibration of a roasting apparatus

The invention concerns a system () of a package () containing a product and an apparatus () using said product, the apparatus being refilled by the product contained in the package, wherein a code () related to the contained product is associated to the package, said code being a two dimension code and said code presenting a predetermined surface S, and wherein the apparatus comprises a code reader () 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 α and a vertical angle of view β, wherein the apparatus comprises a housing structure () and a cavity () inside the housing structure, wherein the image capturing device is positioned at the back side of the cavity.
