Abstract: An automated beverage preparation apparatus includes: multiple pumps for extracting multiple fluid materials stored in multiple material containers, and pushing the extracted fluid materials to move forward; a fluid output device coupled with the multiple pumps and arranged to operably dispense fluid materials to a beverage container; a user control interface arranged to operably generate a control command; a processing circuit arranged to operably generate a corresponding control signal according to the control command; and a pump control circuit arranged to operably control the multiple pumps according to the control signal. The pump control circuit conducts a layered drink making operation under control of the processing circuit to cause the fluid output device to dispense different fluid materials to the beverage container, so as to automatically form a layered drink/gradient drink having at least two color layers within the beverage container.
