PURPOSE: A vertical screw transporting system with the increased vacuum suction force is provided to have the maximum transferring effect by making an object freely up and down. CONSTITUTION: A vertical screw transporting system with the increased vacuum suction force comprises an air inlet valve(10), a suction storage(20), and a suction blower(30). The air inlet valve is located at a temporary reservoir or a mixing tank(2). The air inlet valve inflows the external air with the switching operating. The suction storage ejects the transfer material through a lower part storage(7) at an upper outlet(6) of a transfer pipe(5) with the switching operating of a bottom gate(22). The suction blower is connected to a suction tube(31) to a suction sub tank. The suction tube has a check valve(32).
