Wakati One

Product Description

Wakati One is a preservation technique for fruits and vegetables in developing countries. Keeping the quality of the crops is essential for expanding both the local market and the highly profitable export market, both drive local economies. With 45% of the crops that end up as waste (UN FAO) there is a lot of room to increase productivity, especially in countries like Kenya and Tanzania. ^Interview ^with ^inventor

Design Specifications

The Wakati consists of a tent-like structure with a 10-watt, photovoltaic solar-powered fan and water tray evaporator inside. A ventilator powered by a 10-watt solar panel gradually evaporates 1 L of water per week, generating a humid environment within the tent that keeps cells intact and prevents mold and fungi from spreading. Each tent is capable of preserving up to 1,000 kilograms of produce for up to eight days, greatly reducing potential food waste and giving farmers more time to sell their crops. Moreover, the tarp packaging of the Wakati can be stored and used at any point to mend ruptures that may form in the tent. The optimal use of Wakati One is outside, in a warm and dry climate.
