NOVELTY - The distillation purification apparatus (400) has a vaporization treatment tower (430) which vaporizes the intermediate bio-diesel fuel. A cooler (440) cools and condenses the vaporized intermediate bio-diesel fuel induced from the vaporization treatment tower, and generates the final bio-diesel fuel. A pressure reduction mechanism (410) pressure-reduces the vaporization treatment tower. A heating tower (406,408) heats the received intermediate bio-diesel fuel, and discharges toward the vaporization treatment tower.    USE - Distillation purification apparatus for use in manufacturing system (claimed) for manufacturing bio-diesel fuel used as fuel for vehicle from edible waste oil.    ADVANTAGE - Since the intermediate bio-diesel fuel is vaporized with the continuous system under the reduced pressure, the intermediate bio-diesel fuel is efficiently vaporized at temperature lower than the vaporization temperature in normal temperature, and the final bio-diesel fuel is generated.    DETAILED DESCRIPTION - A temporary storage unit (450) is connected to the cooler. The temporary storage unit is provided for introducing and storing the final bio-diesel fuel obtained by condensation with the cooler. The pressure reduction mechanism is provided with a pump (402,417,422) which pressure-reduces the vaporization treatment tower through the cooler by pressure-reducing the temporary storage unit. A first valve is provided in the flow path between the pump and the temporary storage unit. A second valve is provided in the flow path between the temporary storage unit and atmosphere. A third valve is provided in the flow path between the cooler and the temporary storage unit. A fourth valve is provided in the discharge flow path of the temporary storage unit. Each of first valve, second valve, third valve, and fourth valve is a solenoid valve (405,411-413). An oil detector is provided for detecting that the final bio-diesel fuel stored by the temporary storage unit reaches predetermined amount. The first and third valves are closed, the second and fourth valves are opened by the valve drive control unit, when detected that the final bio-diesel fuel stored by the temporary storage unit reaches predetermined amount. An INDEPENDENT CLAIM is included for a manufacturing system of bio-diesel fuel comprising a valve drive control unit for opening first and third valves, and closing the second and fourth valves, when the predetermined time passes.
