Embodiment Construction

[0026] Reference is now made to embodiments of the invention, one or more examples of which are illustrated in the drawings. The examples are provided by way of explanation of the invention and are not intended as limitations of the invention. For example, features illustrated or described as part of one embodiment can be used with another embodiment to yield still a further embodiment?. It is intended that the present invention embrace these and other modifications and variations as being within the scope and spirit of the invention.

[0027] • In this disclosure, the term "first crack" denotes an important stage during coffee roasting where intensive chemical reactions take place, which lead to the generation of a greater amount of gas within the coffee bean. Because of the pressure, the coffee beans will expand, crack as the gas escapes, and an audible sound and crack will occur. For a batch of coffee beans, the first cracking phase usually lasts several minutes, because ...

Abstract

The present invention proposes a method for controlling a roasting process of coffee beans comprises sampling a first batch of coffee beans and a second batch of coffee beans from said coffee beans during roasting(S12; S42); detecting a surface colour of the first batch of coffee beans(S14; S44); grinding the second batch of coffee beans and detecting a powder colour of the second batch of coffee beans after grinding(S16; S46); and controlling the roasting process at least partially based on the detected surface colour of the first batch of coffee beans and the detected powder colour of the second batch of coffee beans(S18; S48). The present invention also provides apparatus using the above described method.

Description

technical field [0001] The present invention relates to coffee bean roasting management, and in particular, to methods and apparatus for controlling the roasting progress of coffee beans. Background technique [0002] It should be appreciated that the roast level of the coffee beans can be determined during coffee roasting and can be further used to determine the roasting progress. [0003] ?Traditionally, coffee beans are roasted by hand. Heating power and time are always predetermined. Sometimes professionals monitor the surface color changes of the coffee beans during the roasting process and then control or adjust the coffee roasting profile (eg heating power, heating time, etc.) accordingly based on their professional experience. However, many people, especially those ordinary consumers, are often unable to accurately and quantitatively determine a roasting profile?. They don't know how to judge the degree of roasting and how to adjust the roasting profile according ...
