A PLC-based adaptive control of superheated steam treatment system (SSTS) for stabilized brown rice (SBR)
Heat treatment is considered to be one of the most common methods in food drying. However, the problem with this conventional method is that the texture of the food sample is often altered from its original state, just like in brown rice. Superheated steam treatment system (SSTS) is introduced as an...

| 總結: | Heat treatment is considered to be one of the most common methods in food drying. However, the problem with this conventional method is that the texture of the food sample is often altered from its original state, just like in brown rice. Superheated steam treatment system (SSTS) is introduced as an effective method to remove the moisture of the sample. In order to perform process control, a programmable logic controller (PLC), which served as the main controller, is employed to automate the process. To code the PLC program, combination of ladder logic diagrams (LLD), structured texts (ST) and function block diagrams (FBD) were employed using Omron CP1L. The developed controller is also adaptable to different SSTS setting parameters like pressure, temperature (through the temperature controller) and the speed of the transport or conveyorized-driven bed system (through inverter or variable frequency drive). |
