Abstract
The utility model relates to the cooling automatic control device of a cream emulsifying machine, which comprises a water outlet valve, a water inlet valve, a temperature sensor, a signal acquisition unit and a data operation unit. The water outlet valve is arranged on the cooling water outlet pipeline of a cream emulsifying pot. The water inlet valve is arranged on the cooling water inlet pipeline of the cream emulsifying pot of the cream emulsifying machine. The temperature sensor is arranged on the cream emulsifying pot. The signal acquisition unit is used for acquiring the initial temperature value of materials in the cream emulsifying pot during the initial moment of a control period and simultaneously acquiring the real-time temperature values of the materials in the cream emulsifying pot within the control period. According to a cooling enabled instruction, the data operation unit is used for switching on the water outlet valve to start another control period. With each control period, the data operation unit judges whether the difference between a real-time temperature value and an initial temperature value reaches a staged cooling amplitude or not. Based on the judgment result, the data operation unit determines whether to switch on the water inlet valve for cooling or not. In this way, the staged uniform control over the cooling process is realized.
