Hygienic Step-By-Step Makhana Processing Flow
Discover how raw lotus seeds from Katihar wetlands are transformed into 100% pure, untouched, export-grade 7+ jumbo foxnuts under ISO 22000 & FSSAI cleanroom standards.
From Harvest To Nitrogen Sealed Pack
Zero chemical treatment, 100% natural processing, and strict quality checks at every phase.
Wetland Harvest & Aquatic Seed Collection
Local aquatic farmers collect raw lotus seeds (Euryale Ferox) from deep oxbow lakes during the autumn harvest (August - October). The black seeds are washed thoroughly to remove silt.
Sun-Drying & Moisture Calibration
Raw seeds are spread evenly on hygienic raised drying mats under natural sunlight for 3-5 days. Calibrated by digital moisture meters to reach optimal 10-12% moisture level.
High-Temperature Cast Iron Pot Roasting (250°C)
Dried seeds undergo high-heat roasting in cast iron pots at 250°C. Thermal heat loosens the tough outer pericarp shell preparing the kernel for puff expansion.
Precision Popping & Seed Shell Expansion
Roaster seeds are immediately struck with wooden hammers. The rapid pressure release pops the inner endosperm into brilliant, fluffy white makhana kernels.
6-Tier Mechanical Sieve Grading (5+, 6+, 7+ Suta)
Popped makhana is fed into multi-deck rotary sieves. Kernels are sorted by diameter into 5+ Suta (14-16mm), 6+ Suta (16-18mm), and 7+ Super Jumbo (20mm+) grades.
Optical Laser Color Sorting & De-Dusting
Dual-lens high resolution optical sorters remove discolored kernels, dark seed coats, un-popped husks, and micro-particles. Air jets blow away extraneous dust.
