Description
Technical Field
The invention relates to the technical field of ice cream machines, in particular to a method for controlling the rotating speed of a stirring motor of an ice cream machine based on temperature and forming degree.
Background
In the existing ice cream machine, ice cream is formed in an evaporation cylinder in the ice cream machine, and the forming process of ice cream materials is roughly divided into three forming stages, namely a liquid stage, a solid-liquid mixed stage and a solid stage. The ice cream material is continuously stirred by a stirrer in the evaporation cylinder in the forming process.
In the traditional ice cream machine, a stirring motor for driving a stirrer works under rated voltage and rated frequency (rotating speed), the viscosity of ice cream materials in an evaporation cylinder is different in different forming stages, the resistance applied to the stirrer during stirring is changed along with the change of the viscosity of the ice cream materials, and the rotating speed of the motor is naturally reduced according to the design characteristics of the motor of the stirrer along with the increase of the load of the stirring motor.
After the ice cream material in the evaporating cylinder reaches the preset final forming viscosity/hardness, the ice cream machine enters a standby state to maintain the ice cream material in the final viscosity/hardness range.
After the ice cream in the evaporating cylinder is sold, new liquid ice cream slurry can be supplemented into the evaporating cylinder, the average viscosity of the ice cream slurry in the evaporating cylinder can be suddenly reduced at the moment, and the motor rotating speed is naturally improved or restored to the rated rotating speed according to the design characteristics of the motor of the stirring motor along with the reduction of the load of the stirring motor.
The process that the ice cream material is cooled to the freezing point from the liquid state needs a longer period of time, the load of the stirring motor is smaller in the period, the rotating speed of the stirring motor can maintain the rated rotating speed in the period of time, the liquid ice cream material can be uniformly stirred without too high stirring speed, so that the energy waste is caused by the long-time rotation of the stirrer at the rated high speed in the period, and the larger noise is also generated.
In summary, in the conventional ice cream machine, the rotation speed of the stirrer is not controlled reasonably, and when the ice cream material is in a liquid state or the ice cream machine is in a standby state, the rotation speed of the stirrer is excessive, which causes energy waste and increases noise of the ice cream machine.
Chinese patent publication No. CN101129153B discloses a soft ice cream machine with frequency conversion control function, in which a three-phase squirrel-cage asynchronous motor is used as a stirring motor, and frequency conversion control is performed by a first frequency conversion controller, so that the power output of the motor can be controlled by changing the frequency in time according to the cake making process of the soft ice cream machine, and the rotation speed can be controlled. For example, in the initial stage of cake making, the rotating speed can be slightly higher, the ice cream cake body is harder and harder along with the continuous accumulation of the refrigeration process, the resistance is increased, and the current of the stirring motor is increased gradually correspondingly, so that the cake body is low in noise, convenient to adjust the speed, stable in starting torque and high in efficiency during stirring, and the cake body can be adhered uniformly. Although the frequency of the ice cream machine is changed to control the rotating speed of the motor in the initial stage and the process of refrigeration, the refrigeration process is continuously changed along with different working states of feeding, discharging, standby and the like, and the prior art does not have a specific control method for the ice cream machine in different working states.
