The Canadian Malting Barley Technical Centre in Winnipeg, Canada, has installed a sophisticated and automated pilot-scale malting system. The system was designed to produce malt of commercial quality while retaining the flexibility required by researchers and marketers to do applied research work, to evaluate new barley varieties and to develop new products for malting, brewing and food industries. Consultation with malting experts from around the world resulted in a system with many novel features. The system is composed of both a three-vessel malting unit and a single-vessel malting unit. The three vessel system consists of a separate steep tank, germination tank and kiln while the single vessel unit performs steeping, germination and kilning in the same vessel. All of the vessels are cylindrical and are designed to hold a maximum of 100 kg of barley with a bed depth of 1.2 meters and an inside diameter of 0.5 meters. The design allows for accurate replication of commercial malting conditions. The germination vessel and the single-vessel are equipped with centre-pivoted augers to provide for the turning of germinating grain. All vessels are equipped with sensors for temperature, humidity, oxygen and carbon dioxide. Sensors are connected to a data acquisition system to allow for continual monitoring of malting conditions.
