Abstract

The invention discloses a control system of the soft ice cream machine, including a main control plate, a switch plate, a driving plate and a compressor. The input end of the driving plate is connected to mains supply through the controllable transformer, the main control plate, the switch plate and the compressor are respectively connected to the drive plate. The main control plate is also connected to switch plate which is connected to the near switch. The said control system also includes a frequency conversion driving module which can switch the two-phase electric power source to three-phase pulsating direct current electric power source, the input end of the frequency conversion driving module is connected with driving plate and the output end is connected with the compressor. This invention has a closed loop control mode with a high precision of temperature control. The temperature control has the precision in plus-minus 0.2 DEG C and can control the compressor working according to the environment variable. The soft ice cream machine with frequency conversion driving module can reduce the noise, prolong the start moment, guarantee the even running, intelligent fuzzy controlling, wide speed-regulating range, infinite variable speed and energy saving.

Description

technical field [0001] The invention relates to a food machinery control system, in particular to a soft ice cream machine control system. Background technique [0002] The traditional refrigeration compressor starts and runs under full pressure with a fixed-speed compressor under the interruption of the magnetic controller. The starting current is very large, usually 4-6 times of the rated working current, which will have a great impact on the local power grid circuit and seriously interfere with other electrical appliances. Moreover, the compressor and fan on the traditional ice cream equipment are noisy and the speed regulation range is narrow. , the defect of low control precision, resulting in low work efficiency and large energy consumption per unit output. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to overcome the technical defects of traditional soft ice cream machines, and to provide a soft ice cream machine c...
