Drying & Cooling Automation
After roasting, sago quality depends on controlled drying and cooling. OMAC automates these stages with continuous temperature monitoring and PLC logic that runs the drying process — not fixed timers on a switch panel.
Temperature-Led Drying Control
Roasting raises product temperature; drying and cooling must follow in a controlled sequence. We install sensors across dryers and coolers, wire them into your control panel, and let the PLC adjust fans, dampers, and conveyors from live readings.
After roasting — known starting point
Material leaves the roaster at elevated temperature. The automation system tracks that hand-off so drying zones start with the correct setpoints and interlocks — no overlap that overheats or under-dries the batch.
Temperature monitoring — zone by zone
RTD or thermocouple sensors in drying tunnels and beds report product and air temperature to the PLC. Supervisors see live values on HMI; trends and alarms go to SCADA for office oversight.
Automated drying — PLC closes the loop
Instead of operators guessing when to slow a fan or open a damper, PLC logic compares actual temperature to recipe setpoints and drives motor drivers, blowers, and gates automatically until the batch reaches target moisture band.
Cooling stage — safe hand-off to packing
Cooling zones use the same sensor network with separate limits so product reaches packing temperature without re-wetting or thermal shock. Interlocks prevent rushing to bagging while the core is still hot.
Plant-Floor Automation Package
Panel wiring, sensing, PLC programs, and SCADA views matched to how your sago line is laid out after the roaster.
Temperature Sensing
Sensor placement and wiring for drying beds, ducts, and coolers — calibrated inputs the PLC uses every scan cycle.
RTD / TCPLC Drying Logic
Recipes per product grade, fan and damper control, high-temperature alarms, and batch-complete criteria based on temperature profile — not blind timers.
PLCPanel & Motor Drivers
Control panel wiring, motor drivers for blowers and conveyors, and safe interlocks between roasting, drying, and cooling equipment.
PanelHMI & SCADA
Live zone temperatures, setpoint edits, batch logs, and remote overview so management can confirm the drying curve without standing at the dryer.
