Utilization of PLC control on pneumatic powered tofu press machine

Making tofu and the level of production speed in the food industry cannot be separated from fully automatic machines. The press machine knows the pneumatic system with PLC control affects production productivity. Conventional tofu press machines are said not to meet the needs of today's industry because they still use human power, the weight of stones or jerry cans filled with water. The compressive force required when pressing tofu is 15 kg. PLC is an electronic computer that is easy to use (user friendly) and has control functions for various types and various levels of difficulty. At the testing and measurement stage, a power supply with a capacity of 24Volt Dc is used because each sensor requires a voltage of 24Volt Dc, The output of the measurement results on the sensor has different voltage values; from that value, it does not interfere with the sensor's work because the voltage is still following the sensor datasheet. From the results of design testing with a pneumatic trainer where the pneumatic cylinder cycle follows what is expected (A+A-B+C+C-B-). And from the calculation results of the Tofu Press Machine Frame using theSolidworks application is declared safe.
