Beverage supply apparatus

The patent applies continuity of useful action by performing hot water supply and stirring simultaneously during the extraction phase. The control unit controls the hot-water supply unit to add hot water to the extractor during extraction, and the pressurized air supply unit supplies pressurized air to stir the ingredient and hot water at the same time. This eliminates the need for separate stirring steps after extraction, maintaining continuous productive action and reducing total beverage supply time.

The patent merges the stirring function and extraction function into a single integrated process. By controlling the hot-water supply unit and pressurized air supply unit to operate simultaneously during extraction, the patent combines what were previously separate sequential operations (extraction then stirring) into a concurrent unified process, thereby reducing the total time required for beverage supply.

When the supply amount equals or exceeds the extractor volume, the patent maintains continuous productive action by supplying hot water and pressurized air simultaneously throughout the extraction process. This allows the system to efficiently handle larger volumes without requiring multiple discrete stirring cycles, as the concurrent hot water supply and stirring during extraction continuously processes the ingredient through the entire beverage supply amount.

The patent applies preliminary action by supplying hot water to the extractor before and during the extraction process. The control unit controls the hot-water supply unit to add hot water during extraction, ensuring the ingredient is pre-heated and prepared for efficient extraction from the outset, rather than waiting for extraction to complete before adding hot water for stirring.
