Coffee bean roasting method, mobile terminal device and computer program product

The invention relates to a coffee bean roasting method which comprises the following steps that: a mobile terminal device displays an operation interface for operation to generate and transmit a control signal to a coffee bean roasting machine so as to enable the coffee bean roasting machine to roast coffee beans according to the control signal; the mobile terminal device requires the coffee bean roasting machine to continuously transmit a current roasting temperature to the mobile terminal device, so that the mobile terminal device generates a roasting temperature curve changing along with time in real time according to the roasting temperature transmitted by the coffee bean roasting machine; and the baking temperature curve and the operation interface are displayed on the same display image. 一种咖啡豆烘焙方法，包括由一移动终端装置显示一操作界面供操作以产生并传送一控制信号至一咖啡豆烘焙机，使该咖啡豆烘焙机根据该控制信号烘焙咖啡豆，且该移动终端装置要求该咖啡豆烘焙机持续地传送当下的一烘焙温度至该移动终端装置，使该移动终端装置根据该咖啡豆烘焙机传来的该烘焙温度实时产生随时间变化的一烘焙温度曲线，并将该烘焙温度曲线及该操作界面显示于同一显示画面。
