Problem Addressed
Washing walnuts is labour-intensive and time-consuming. Within 15 minutes, ten kg of walnuts can be washed manually but still the same remains unclean. Few farmers tried acid wash to bring a shine to the shells, but this adversely affected the taste of the nuts.
Technology
The Easy-Go Walnut Washer uses a one HP single-phase motor running at 900 RPM, connected to a pulley belt system. This drives wire-threaded brushes along a shaft that cleans 40 kg of walnuts per five to seven-minute wash cycle. It can deep clean 480 kg per hour with 95% efficiency.
Societal Impact
This accessible and inexpensive washer minimises water usage to just 20 L per cycle. It reduces exposure to harmful chemicals used in traditional walnut processing.
