A apparatus () for roasting coffee beans is disclosed comprising a compartment () for holding coffee beans (); a roasting element () for roasting the coffee beans in said compartment; and a processor () comprising a control unit () for controlling the roasting element. Wherein, the processor () is adapted to determine a weight loss rate of the coffee beans, and the control unit () is adapted to control the roasting element as a function of the determined weight loss rate. A coffee machine including such an apparatus and a method for roasting coffee beans are also disclosed.

Apparatus and method for roasting coffee beans, and coffee machine

A coffee roasting apparatus is disclosed comprising a compartment for holding coffee beans, a heating arrangement for heating the coffee beans in the compartment during a roasting process of the coffee beans, a volatile organic compound sensor for determining a total concentration of volatile organic compounds residing in the compartment, and a controller for controlling the heating arrangement. The controller is adapted to determine whether a rate of change in the total concentration of volatile organic compounds exceeds a predefined threshold and control the heating arrangement based on a determination that the rate of change in the total concentration of volatile organic compounds exceeds the predefined threshold. A coffee brewing apparatus including such a coffee roasting apparatus and a coffee roasting method are also disclosed.

Coffee roasting apparatus, coffee brewing apparatus and coffee roasting method

A coffee processing apparatus () is disclosed that comprises at least one of a grinding stage () for grinding coffee beans () into ground coffee beans (); and a brewing stage () for brewing coffee from ground coffee beans; the coffee processing apparatus further comprising a sensor () arranged to sense a total concentration of volatile organic compounds released by said coffee beans or ground coffee beans; and a controller () responsive to said sensor and arranged to control said grinding stage and/or said brewing stage as a function of said total concentration. Methods of controlling such a coffee processing apparatus are also disclosed.

Coffee processing apparatus and method

A coffee roasting apparatus including a compartment for holding coffee beans; a roasting element for roasting the coffee beans in the compartment; and a controller for controlling the roasting element. The controller is configured to control the roasting element as a function of a rate of change in the volume of the coffee beans residing in the compartment.

A coffee roasting apparatus is disclosed that comprises a compartment for holding coffee beans; a roasting element for roasting the coffee beans in said compartment; a controller for controlling the roasting element; and a sensor for monitoring a total amount of volatile organic compounds (VOCs) released by said coffee beans during roasting and providing the controller with an indication of said monitored amount. The controller is adapted to receive an indication of the total weight of the coffee beans in the compartment and control the roasting element as a function of the indication of the monitored total amount and the indication of the total weight, said function defining the total VOC release characteristics of said coffee beans during roasting. A coffee brewing apparatus and coffee roasting method are also disclosed.
