PIKKOLO is a compact, cylindrical solar dehydrator (30x60x30 cm) designed for urban apartment residents and home cooks. It provides a hygienic, electricity-free way to dry and ferment foods using passive solar heat and low-power fan circulation. Its modular design allows for easy cleaning and repair, reducing waste and material use. It operates entirely on solar energy, cutting down grid electricity use and helping households preserve small harvests to reduce food waste.
