PURPOSE: An apparatus and a method for preventing dispersion of power materials of a vending machine are provided to prevent the dispersion of the power materials by operating an exhaust motor after injecting fully the powder materials into a cup. CONSTITUTION: An apparatus for preventing dispersion of power materials of a vending machine includes a control panel(20), a micro-computer(30), a raw material input/output driving unit(50), and an exhaust motor(120). The micro computer(30) includes an exhaust motor controller. The exhaust motor controller is used for stopping an operation of the exhaust motor(120) to prevent the dispersion of the powder materials when the raw material input/output driving unit(50) is operated. The exhaust motor(120) is operated by a control operation of the exhaust motor controller after the powder materials are fully injected into a cup. |
