Modern Agro-Technology: Automated Roasting Machines and Optical Sorters in Makhana Mills

From Artisanal Hearth to High-Throughput Processing

For centuries, makhana popping was entirely performed by manual wood-fired earthen hearth roasting and wooden mallet thumping. Today, high-precision agro-industrial engineering is revolutionizing processing throughput while preserving the pristine organic purity of the Mithila harvest.

Next-Gen Processing Machinery

  • Continuous Multi-Deck Drum Roasters: Controlled LPG/electric infrared heating drums ensure uniform heat distribution across calibrated Gordi seeds, eliminating burnt kernels.
  • Pneumatic Impact Poppers: Instantaneous pressure drop chambers that pop up to 120 kg/hour of expanded Lava with over 92% puff expansion ratios.
  • Trichromatic High-Resolution Optical Sorters: Advanced CCD cameras scanning 15,000 kernels per second, instantly ejecting blackened pericarp pieces, undersized kernels, and foreign matter.
