Method of predicting scheduled time of occurrence of gobase of coffee beans, prediction apparatus for predicting coffee bean haze occurrence, coffee bean gobo detecting method, coffee bean gobo detecting apparatus, and roasted coffee bean manufacturing method

摘要

To provide a method for easily or accurately detecting or predicting the occurrence timing of goby during roasting of coffee beans.SOLUTION: The goby detecting method of coffee beans according to the present invention comprises a sound measuring step of measuring a sound generated from coffee beans being roasted over time and a sound measuring step of measuring a sound included in a range of 5 kHz or more and 80 kHz or less And a gauze detecting step of detecting a gobase of coffee beans based on the sound pressure of the frequency of the coffee beans. It is preferable to start the sound measurement process from 2 minutes after the start of roasting. It is preferable to further have an initial carbon monoxide amount measuring step of measuring the amount of carbon monoxide generated from coffee beans being roasted at least until two minutes after the start of roasting.(FIG.
