PURPOSE: A Dutch coffee vending machine is provided to offer a sense of aesthetic to customers by allowing the customers to check a Dutch coffee extraction process with the naked eye. CONSTITUTION: A Dutch coffee extraction unit (10) shows a Dutch coffee extraction process and includes a vertical support (11), a water supply unit, a coffee bean storage unit, and an undiluted solution storage unit. The vertical support connects an upper support (11a), a middle support (11b), and a lower support (11c). The water supply unit discharges water from a lower valve of the upper support. The water supply unit and the undiluted solution storage unit are connected to connect the inside by a circulation hose. The circulation hose is connected to a circulation pump and circulates an undiluted coffee solution in the diluted solution storage unit to the inside of the water supply unit. The circulation pump is connected to a water level sensing unit which senses the water level of the water supply unit. A display unit (30) is formed on a vending machine body. A sensing unit (40) is connected to the display unit. An undiluted solution supply body (50) discharges an undiluted solution container with the undiluted solution by the piece. A control unit is connected to the display unit, the sensing unit, and the undiluted solution supply body. |
