Project description
In collaboration with the International Rice Research Institute (IRRI and the University of Hohenheim, GrainPro, Inc. have designed the GrainSafeTM Dry (GSD). The GSD combines in-store drying with hermetic grain storage. In-store drying aims to control the relative humidity of the drying air, so that all grain layers in the deep bed reach equilibrium moisture content. This is possible as a blower that runs on solar power, pushes warm air at the bottom of the device into the grain bulk until the desired humidity level is reached. In hermetic storage the grains are enclosed in an airtight container made from material with very low oxygen permeability, protecting the grains from insects and water reabsorption. Combining the in-store dryer with the hermetic storage properties allows drying and storing food in a protected environment. Including a drying controller allows increasing energy efficiency adapting the blower speed to the relative humidity. With a capacity of 1 to 5 tons of rice, and anticipated system costs of $ 1,100, the GSD still needs to be tested and optimized before a commercial prototype can be developed.
