Method to check a coffee beans roasting system

Abstract

The invention concerns a method to check a roasting system (), said system comprising: —a roasting apparatus (), said apparatus producing smoke, and—a smoke treating unit () configured to treat the flow of smoke produced by the roasting apparatus and comprising: at least one smoke filtering device (), a dismountable smoke collecting device () at least one temperature sensor () configured to measure the temperature T of the flow of smoke inside the smoke treating unit (), a smoke driver () configured to drive smoke from the roasting apparatus () through said smoke treating unit, wherein the method comprises the steps of: —operating the roasting apparatus in order to produce hot gas, —monitoring the temperature of the smoke, and—observing at least one behaviour of the monitored temperature along time, —comparing said at least one observed behaviour of the monitored temperature with a predetermined behaviour of temperature corresponding to the presence of the dismountable smoke collecting device () inside the smoke treating unit, —if the at least one observed behaviour diverges from the corresponding predetermined behaviour, then displaying an alarm.
