Problems solved by technology

However, this approach also has disadvantages, including the signal-to-noise ratio when the roasting process itself creates a lot of noise and only a vague crackling sound when the roasting temperature is not high enough

Embodiment Construction

[0039] figure 1 A process involving the determination of the initial degree of roasting of coffee beans, which can be carried out automatically in an apparatus comprising measuring means and control means, without requiring action / input from the user. figure 2 and 3 A graph illustrating the rationale for the process is shown, where the curve figure 2 involves initially raw coffee beans where the curve image 3 relates to coffee beans that were initially partially roasted, and where it is true for both graphs that the values ​​on the x-axis represent the roasting time in seconds and the values ​​on the y-axis represent the roasting time in μg / m 3 counted particles. Based on the processes of separately roasting green and partially roasted beans (performed in the context of a study on the feasibility of the present invention), and by performing real-time measurements of the total particulate matter emitted from the beans during those processes, the curves were found picture...

Abstract

A device for use in a process for roasting coffee beans comprises measuring means (10) for performing measurements of an actual value of particulate matter emission from the coffee beans during a process of roasting the coffee beans, and controlling means (20) coupled to the measuring means (10) for receiving the outcome of the measurements from the measuring means (10), wherein the controlling means (20) are adapted to find a pattern of the particulate matter emission over time on the basis of the outcome of the measurements, to determine an actual roasting degree of the coffee beans on the basis of the pattern, and to determine and set at least one characteristic of the roasting process on the basis of the roasting degree.

Description

technical field [0001] The present invention relates to a method for controlling the process of roasting coffee beans. Furthermore, the invention relates to a device for use in the process of roasting coffee beans. Background technique [0002] In the field of coffee making, there is an increasing demand among consumers for freshly roasted coffee beans to be used in the process. Currently available home roasters generally preset the characteristics of the roasting process for the consumer, without offering the possibility of adapting those characteristics to the initial degree of roasting of the coffee beans. Thus, it can happen that when a consumer decides to use part roasted beans instead of green beans, the standard duration of the roasting process is actually too long to achieve a good result, where the coffee will taste better than the consumer expects Much more bitter. Where it is possible for the consumer to set characteristics of the roasting process, such as temp...
