Field curing and trim
Optical caliber sorting
Fumigation and bagging
Reefer container stowage
Harvested small onions dry on raised racks under shade-net sheds for five days until the outer tunics cure completely, preventing latent moisture build-up.
Vibratory screens and dual-channel optical sorters grade bulbs into twenty to twenty-seven millimeter brackets, eliminating split cores and neck rot.
Bulbs enter sealed degassing chambers for official phytosanitary treatment before automated packing into UV-stabilized five to twenty kilogram red mesh sacks.
Palletized sacks load into pre-cooled marine containers with bottom-air delivery vents set at eighty-five percent humidity to suppress root germination.
Pulp temperature and skin density
Before pallet strapping, our quality control inspectors sample five sacks per metric ton. Digital calipers confirm strict sizing bands while needle hygrometers verify interior bulb moisture stays below target thresholds.
Export certificates of origin, fumigation endorsements, and bills of lading clear customs desks at Tuticorin or Chennai before vessel cut-offs, preventing port detention.
Verify regional port transit times
Direct road transit to Tuticorin, Cochin and Chennai terminals ensures prompt connection to key Gulf, European, and Southeast Asian liner schedules.
