Continuous Tower for
Regional Grain Depot

A regional grain depot in the Philippines installed a GXON G-CT Series continuous drying tower with indirect heat exchange and PLC auto-control. The system runs 24/7 unattended — delivering export-grade moisture uniformity across rice and maize batches during peak typhoon-season intake.

CUSTOMER BACKGROUND & CHALLENGE

Typhoon-Season Intake at Industrial Scale

Regional grain depots must process large volumes fast — typhoon-season harvests arrive wet and must be dried continuously to prevent spoilage across thousands of tons.

A Depot Under Peak-Season Pressure

A regional grain depot in the Philippines aggregates rice and maize from surrounding provinces. During the typhoon-season harvest, intake volumes spike dramatically — and grain arrives at moisture levels far above safe storage thresholds.

Batch drying cannot keep pace with the intake volume. The depot needs continuous, unattended operation that runs day and night without requiring a large operator workforce to be present at all hours.

Quality at Scale

For export and government reserve standards, moisture uniformity is critical. Direct-heat drying risks contamination and fissuring. The depot requires indirect heat exchange — where flue gas never contacts the grain — and PLC control that maintains precise temperature across all moisture levels.

SOLUTION CONFIGURATION

Engineered for Industrial Scale

Three core components configured for continuous depot-scale drying: continuous tower, indirect heat exchange, and PLC auto-control for 24/7 operation.

Indirect Heat Exchange
Flue gas heats clean air in a heat exchanger — combustion gas never contacts grain. Ensures export-grade quality with no contamination risk across all fuel types.

IMPLEMENTATION PROCESS

From Survey to 24/7 Operation

Four engineering stages to deploy a continuous drying tower at a regional grain depot.

1
Site Survey
Engineers assessed depot layout, intake volume projections, and fuel supply for continuous round-the-clock operation.
2
Engineering
Continuous tower sized for peak-season TPD, configured with indirect heat exchanger and multi-fuel burner.
3
Installation
Tower erected, heat exchanger integrated, PLC system commissioned for unattended continuous operation.
4
Training
Depot staff trained on PLC monitoring, alarm response, and routine maintenance for continuous operation.
OUTCOMES & BENEFITS

What This Deployment Delivered

Quantified impact for the regional grain depot during peak typhoon-season intake.

TPD Throughput
Peak-Season Capacity
Continuous flow handles typhoon-season intake volumes that batch drying cannot match — no grain waits in line.
% Fuel Saved
Energy Efficiency
Indirect heat exchange and continuous operation optimize fuel use per ton dried — reducing operating cost at scale.
Hrs Unattended
24/7 Auto-Operation
PLC auto-control runs the tower day and night with real-time monitoring — minimal operator presence needed.
The tower runs day and night without us watching it. During typhoon season, that is the difference between saving the harvest and losing it.
