The Khakhra Making machine is used for roasting khakhra. The raw dough balls are placed on conveyer belt on one side and on other side we get fully roated and ready to eat khakhra. In today’s fully automated age this type of automatic khakhra making machines are used to make khakhra and we solved the application with wecon plc and hmi Process Overview: Machine uses hydraulic motor and pressing mechanism for pressing the raw dough into flat khakhra and then it goes ahead to heating zone through conveyer belt where kharkhra are roasted according to recipe and then goes to packing.Inputs are proximity sensors and emergency switch.Outputs include Up and down solenoid valves, conveyer motor,hydraulic motor and oil spray valve. Solution:
Plc Used : Lx3v-0806 MR-A2 – 1 Nos.
Hmi Used : PI8070 – 1Nos.
Yudian : Ai-7048 – 2 Nos.
Communication Details: PLC
COM1 : Rs422 Plc to Hmi
COM1 : Rs422 Wecon Lx3v Protocol
COM2 : Rs485 Yd protocol for Ai-7048
Here PLC is used to control the output logic of machine and heating is controlled by yudian AI-7048 blind controller. And hmi acts as a display for operating machine and setting different recipes of Khakhra.
