REDC’s Solar Food Preservation Facility helps rural small-scale farmers in developing nations preserve nutritious food at the harvest stage. Crops that are ripe are picked and placed in the walk-in cooler then sold to local customers, market vendors, grocery stores, restaurants and hotels. Before the nutritious food can spoil in the walk-in cooler they are preserved long-term in the glass jar canning station. New baby foods, fruits, vegetables, dairy, roots, tubers, meats, fish, poultry, and new premade native meals / stews provide the farmer with new revenue streams, year-round. When farmers have the Solar Food Preservation Facility on site, food waste is reduced to almost zero and the business of farming expands. The Solar Food Preservation Facility turns normally wasted food into profits and maximizes productivity per Hectare for the farmer without needing access to electricity.
REDC uses the thermal energy from the sun to refrigerate the walk-in cooler and boil water in the canning station. REDC concentrates the sun’s rays with a parabolic reflector onto REDC’s Solar Heat Exchanger. The sun’s rays heat sunflower seed oil (high flash point and environmentally friendly) up to 400oF. The hot oil is circulated through a closed loop system by a 12 volt gear pump, which is powered by a small solar cell and 12 volt battery. Hot oil fills REDC’s Ammonia Absorption Refrigeration Heat Exchanger. The heat exchanger transfers heat from the hot oil to the ammonia absorption solution. The ammonia solution boils and refrigeration takes place inside the walk-in cooler.
The walk-in cooler does not exhaust all of the heat out of the oil. REDC uses this excess energy to boil water in REDC’s Glass Jar Canning Kettle. By simply opening and closing a valve, water can be boiled in the kettle. REDC’s Canning Kettle is double walled with open space between the base and walls of the kettle. Hot oil fills the kettle from the bottom-up. Oil enters the bottom, fills between the walls and exits at the top. Heat penetrates the base and inner walls until water boils at 212oF. All food can now be warm bath or pressure canned in glass jars. The farmer now stores the canned food on shelves for consumption and sale later.
This breakthrough clean energy technology can help farmers supply their nations with fresh, low-cost, nutritious food, year-round, while operating a sustainable and profitable business. Pregnant and nursing mothers can now provide their babies with fresh, low-cost, nutritious food, all year. With REDC’s Solar Food Preservation Facility, farmers can reduce malnutrition and childhood mortality, one community at a time.
