A controller for a mixer that includes a housing, a cup body disposed on the housing, a motor and a fan disposed within the housing and a mixing part disposed within the cup body and co-axially connected to the motor, wherein the fan and the motor are opposite to each other, including:

• a first operation control unit, for sending a fan initiation control signal to the fan when obtaining a instruction for initiating the mix from a user, to allow the fan to operate at a pre-set fan rotation speed;
• a second operation control unit, for sending a motor initiation control signal to the motor, to allow the motor to operate at a pre-set motor rotation speed within a set mixing time period;
• wherein the instruction for initiating the mix includes the mixing time period;
• a first stop control unit, for sending a motor stop control signal to the motor when the mixing time period is ended, to stop the operation of the motor;
• and
• a second stop control unit, for sending a fan stop control signal to the fan after a pre-set first delayed time period, to stop the operation of the fan.
