Grain Drying and Silo Ventilation

To maintain the quality and storability of free-flowing products such as grain, corn, rice, and oilseeds, and to reduce post-harvest losses, grain drying and silo ventilation equipment is used.

To maximize crop throughput in the seasonal operation and keep operating costs as low as possible, drying equipment should be designed to be energy efficient. Optimal matching of the warm air generator, dryer and blower is a prerequisite for gentle and energy-efficient crop drying. A highly efficient blower can make a decisive contribution to reducing drying time by providing high volume flow at low power consumption. Depending on the yield and weather-related moisture content of the crop, the required drying capacity of a grain dryer varies, and with it the volume flow and static pressure to be generated by the centrifugal blower.

In addition to a high efficiency in the operating range of the plant, the blower used should be as space-saving as possible and have a low weight in order to keep the installation and maintenance effort low. The latter applies in particular to mobile aeration blowers used in joint ventures or contractors. If the drying plant or the blower for silo aeration is used in the vicinity of residential areas, the high acoustic requirements of the fan wheels or fans used must also be taken into account.
