SelfChill Webinar

Sustainable Cooling Technologies For Preservation Of Crops

The Nigerian Stored Products Research Institute (NSPRI) in collaboration with Phaesun and Solar Cooling Engineering, Germany, invites you to a training programme on “Solar Cooling Technologies for Reducing Postharvest Food Losses”.


Nigeria produces over 10 million tonnes of fruits and vegetables annually. Studies have shown that post-harvest losses in these commodities can be as high as 50% especially in the rural communities. The high losses are attributed to poor handling and storage coupled with poorly developed cold chain and irregular electricity supply. Application of solar cooling technologies is a sustainable solution to the problem of cold chain and has the potential of reducing postharvest losses in fresh commodities.

NSPRI, Ilorin, Nigeria has the mandate of conducting research into postharvest management of crops grown and consumed in Nigeria with the goal of reducing postharvest food losses and improving food and nutrition security. The German partners, Solar Cooling Engineering GmbH and Phaesun GmbH have been in research on solar cooling technologies since 2013 and have implemented solar cooling solutions for fruits and vegetables, and milk cooling systems under the brand SelfChill®. The consortium offers workshops and training series targeting stakeholders from the agricultural sector, cold-chain business, scientists and technicians.
