Smart Solar Drying
Reduce post-harvest losses and improve incomes
The Challenge
Every year, farmers across Africa lose 30-50% of their harvest due to inefficient drying methods. Traditional open-air sun drying takes 5-7 days, exposing crops to contamination from dust, pests, and unexpected rainfall. These losses not only impact farmers' income but also contribute to food insecurity and reduced market opportunities. For smallholder farmers, accessing modern drying technology has been prohibitively expensive, leaving them trapped in a cycle of post-harvest losses.
The Solution
Synnefa's Smart Solar Dryer revolutionizes post-harvest processing by combining greenhouse technology with intelligent monitoring systems. Our solution transforms traditional solar drying into a precise, controlled process that reduces drying time to just 2-3 days while maintaining product quality. Through flexible ownership, financing, and service options, cooperatives and agribusinessescan access this technology at the right cost structure for their business.
Key Innovation Features
The Greenhouse Solar Dryer provides a controlled environment that protects crops while maximizing natural solar energy. It comes complete with tables and racks to allow you spread your produce and take advantage of vertical height to dry more volume. The design allows movement of hot air evenly across all surfaces ensuring even distribution of drying
Our FarmShield™ IoT sensors continuously monitors temperature, humidity, and drying conditions and connect to the FarmCloud™software platform to deliver real-time insights and alerts directly to operators' phones, ensuring optimal drying results every time. This integrated approach, combined with solar-powered HVAC fans, delivers consistent, high-quality dried products that command premium market prices.
Our Eco-friendly greenhouse design maximizes natural solar energy for optimal drying conditions. This efficiency is further increased by our Heating, Ventilation, and Air Conditioning-HVAC fans and sensors which are fully powered by solar reducing energy costs and environmental impact and saving carbon emissions when compared to fuel powered drying equipment. Our smart solar dryers come complete with batteries to ensure they HVAC fans operate even at night!
