Axion One X720 for Post-Wash Drying on Potato Lines

Axion One X720

Galex's Axion One X720 high-speed turbo blower is applied to surface drying on potato washing lines, a step that determines whether washed tubers can move directly to optical sorting and packing.

Potatoes leave the washer carrying a film of free water. Left in place, that film interferes with optical sorters, which grade on colour and surface defects, and it introduces moisture into sealed retail packs, where condensation promotes mould growth and drives returns from supermarket buyers. Drying between washing and sorting is therefore a process requirement rather than a finishing touch.

In such installations the X720 feeds an air knife mounted above the conveyor. The blower is rated at 7.5 kW and delivers 18 m³/min at 200 mbar — the highest flow rating among the three Axion One models, and the figure that governs air-knife performance, since surface moisture is stripped by air velocity at the nozzle rather than by static pressure.

The X720 delivers oil-free air, with no lubricant in the air path — a requirement where the discharge stream contacts food product. The unit is supplied with a stainless steel enclosure for the wet and humid conditions of a packing line. Intake air passes through Galex QuickDraw fine filtration, rated F9 to EN 779, with a 2,000-hour service interval. Sound pressure is below 80 dB(A), and the blower carries CE certification. Local control is handled by a touch HMI, with MODBUS available for line integration.
