Abstract

This invention is a new, energy efficient, environmentally clean grain drying system which consists of two main parts: a hot drying air generator and a modular, portable drying bin. One novel aspect of the air generator is the introduction of a heat pipe design which enhances the efficiency of a dehumidifier heat pump, making its use economically feasible, especially for humid climates. Another novel aspect is the use of advanced burners incorporating antipollution devices. The hot air generator can operate on many sources of energy such as electricity; gasoline; diesel; biomass such as wood, charcoal, or rice husks; or even solar energy. The modular bin is made of several modules which can be disassembled, transported, and reassembled with great ease. The bin design also creates a very low air pressure drop, allowing substantial savings on blower energy. The complete system will offer great benefits for developing countries that are producers of rice, especially for those with humid climates. With this advanced dryer system, the small producers of rice located far from means of transportation can preserve their harvest and offer higher quality products at a lower production cost.
