Method for controlling rotating speed of stirring motor of ice cream machine based on temperature and forming degree

Abstract

The invention discloses a method for controlling the rotating speed of a stirring motor of an ice cream machine based on temperature and forming degree, the ice cream machine further comprises a control system, the control system comprises a main controller, a temperature monitoring module and a frequency converter, and the frequency converter is connected with the stirring motor and used for adjusting the input frequency of the stirring motor. The temperature monitoring module is used for monitoring the temperature of the ice cream material in the evaporation cylinder or the air return temperature value of the evaporation cylinder and transmitting the temperature monitoring value to the main controller, and the frequency converter obtains the real-time working torque value of the stirring motor and transmitts the monitored working torque value to the main controller so as to obtain the real-time forming degree proportion value of the ice cream in the evaporation cylinder, and the main controller adjusts the output power frequency of the frequency converter according to any one or the combination of the temperature monitoring value and the real-time forming degree proportion value and the rotating speed of the stirring motor is further adjusted. The energy consumption and noise of the ice cream machine can be reduced.

Description

Technical field [0001] The present invention relates to the technical field of ice cream machines, and in particular, a method of controlling ice cream press based on temperature and molding. Background technique [0002] The existing ice cream machine, ice cream is formed in the evaporation cylinder in the ice cream machine, and the molding process of ice cream is roughly divided into three forming stages in the liquid stage, solid-liquid mixing stage and solid state stage. The ice cream is continuously stirred by the agitator in the cylinder during molding. [0003] Traditional ice cream machine, the stirring motor of the drive stirrer during the working process of the rated voltage and rated frequency (speed), in different forming stages, the viscosity of the ice cream is different in the evaporation cylinder, and the resistance of the stirrer is also affected. As the viscosity changes in ice cream, the motor speed is naturally lowered according to its own motor design charact...
