This solar dryer is intended for the small landholder or a family. With a capacity of 10 - 200 kg of sliced wet fruit or vegetables, depending on type of fruit and numerous other factors (see ‘Millionsun Capacities and Procedures’ document), this dryer is ideal for high-quality natural preservation in a micro-enterprise setting. multiple units provide a significant commercial volume at a combined costwhich remains economical and substantially lower than large commercial solar dryers.
Model (shown on work table) with solar air collector set at 30 degrees. This setting is suitablefor temperate latitudes. The setting of the collector can be easily adjusted between 20o and 45ofor the seasonal changes of solar angle or for various latitudes.
It is well known that most fruits and vegetables (or herbs and even fish) are often available in seasonal gluts when the prices are extremely low and vendors and growers can hardly sell for any profit. During such times, consumers and producers can benefit greatly with the practice of drying for later consumption and food security or for commercial sale.
Enclosed drying in a solar-powered cabinet dryer is far superior to traditional sun drying in the open air or in dryers which expose the food to direct sunlight. Drying in the open air is unsanitary and attracts insects and other pests. Meanwhile direct exposure to sunlight either in the open air or in a dryer which lets sunlight in, allows UV rays to penetrate the food which degrades the nutritional content and also causes discoloration and very tough texture.
