PURPOSE: A direct contact-type drier, making use of vibration is provided to maximize the drying effect of moisture through sequential drying by connecting a raw material drier in multi-stages while powered raw materials including moisture are input into the center of a drying plate and vibration is produced. CONSTITUTION: A direct contact-type drier(100), making use of vibration comprises an oscillator(140) producing vibration by the driving of a vibrator; a raw material drier(110) detachably installed to the upper part of the oscillator; and a discharge fan(119) discharging moisture in the raw material drier to the outside. The raw material drier is mounted and assembled in multi-stages. The raw material drier comprises a drier body(112) of a cylinder shape; a raw material guide plate(114) gathering powdered raw materials, input to the inner upper side of the drier body, to a set point of the center and then guiding the powdered raw materials to the lower part; a drying plate(116) forming plural raw material discharge grooves(116a) to the edge and drying the powdered raw materials input to the upper center part from the set point of the center of the raw material guide plate while moving the powdered raw materials to the radial edge through vibration; and a heat medium supply unit(118) installed to the upper surface of the drying plate, to heat the input powdered raw materials. A heat medium input port(118a) and a heat medium discharge port(118b) are formed to the sides of the drier body. The heat medium input port and the heat medium discharge port are interconnected. A moisture discharge port is formed to the upper part of the drier body of each stage. The discharge fan is connected to the moisture discharge port.
