Hada Co Ltd.‘s "Purigo Orchard Spraying Robot" is a revolutionary product that has redefined conventional 500-liter engine-powered sprayers that have seen no technological advancements for 20 years.
The electric robot performs the same spraying tasks with only 15.1% of the power (59.5 kW for conventional sprayers, 9 kW for Purigo), consuming six times less energy than traditional systems. Through this innovation, Purigo has achieved unprecedented energy-saving technology and successfully transitioned to eco-friendly electric technology, dramatically reducing operational energy. Purigo sets a new standard for orchard management and paves the way for the future of sustainable agriculture.
Purigo’s energy-saving technology is realized through two major engineering innovations. First, the distance between all spray nozzles and the crops has been significantly minimized compared to traditional methods, and an independent blower system for each nozzle replaces the conventional integrated blower, reducing energy waste. Second, the conventional fossil fuel-based, heavy-weight powertrain and central blower system have been replaced, reducing the weight of the sprayer by 49.5% (from 1,395 kg to 705 kg), further conserving operating energy.
Additionally, the ground-based Purigo Spraying Robot offers greater efficiency than drones, thanks to its large tank capacity of over 500 liters, extended operating time of 5 hours, precise close-range spraying, lower susceptibility to weather conditions, reduced chemical drift, and cost-effectiveness. For large-scale orchards, Purigo provides minimal downtime (for refilling or battery charging) and ensures consistent and precise chemical application.
Purigo is compatible with most diluted liquid pesticides (including water-soluble and suspension concentrates), except for solid formulations such as GM, offering a wide range of applications.
