Digital services for the optimisation of the grain drying process

by Volker Josel, Product Manager, Bühler GmbH, Germany

High yield and ultimate homogeneity of the product are the main dryer requirements of a grain collection point operator. For this the energy input should be minimal, the drying process has to run without any disturbance and the product needs to be dried as close to the target moisture as possible. As a grain dryer is not an isolated element in the collection point, the interaction of the drying process with the other processes must be seamless.
 

Over the years, various improvements in the design of grain dryers have increased their energy efficiency. One example is the reuse of heating energy, whereby an air recirculation system not saturated but hot exhaust air is fed back into the supply air for the drying of grain, saving up to 20 percent of the energy required for heating. Another example is Bühler’s Eco Cool, which is used for the drying of very moist corn that has an input moisture of more than 30 percent. Eco Cool is a conditioning and cooling section after the actual corn dryer that enables a further 15-20 percent of the heating energy to be saved.

While there are many examples of such mechanical dryer optimisations, tight margins and sustainability issues are also driving the need for further optimisation of the drying process to continuously reduce energy consumption, losses and waste.
