Abstract: Proposed is a vertically movable mixer including a container comprising a bottom portion in which a central through-hole is formed, a motor housing coupled to the container under the container, a motor built in the motor housing, a sliding member configured to reciprocally slidably move in a vertical direction through the central through-hole of the container, a rotatable shaft rotatably installed in the sliding member so as to be configured to reciprocally slidably move in the vertical direction in conjunction with the sliding member and axially mounted on a motor shaft of the motor so as to be configured to rotate by rotation of the motor, and a rotatable blade mounted on the rotatable shaft and configured to cut, grind, and mill food contained in the container while rotating and while reciprocally slidably moving in the vertical direction.
