Barley intake is received via the GrainCorp Terminal and conveyed to the BBM barley storage bins.
The malthouse combines precise process control with high capital efficiency. At Pinkenba the conversion of barley into malt begins at the Wetting Steeps
where cleaned barley is subjected to steeping programs of up to 48 hours. At the completion of the steeping program, the batch is conveyed to one of
the circular germination vessels where it remains for four days. Kilning completes the
process and is carried out over twenty hours in a very high efficiency single deck circular kiln. The entire plant is computer monitored and is designed for maximum economy in the utilization of all resources.

Strict control is applied to all incoming barley. Raw material quality control encompassing varietal purity, appearance, protein content, moisture and screenings content is closely monitored for adherence to our malting barley specification. Prior to processing, grain is physically screened and dressed
Batch size is 360 Tonne with a 48 hr maximum steeping cycle.
Steeping configuration incorporates 12 x 60 Tonne capacity conical steeping tanks with multiple immersion steeping, aeration and CO2 extraction.
Steeping program and steep temperatures are monitored continuously. Steep grain is dry transferred to the Germination Vessels (GVs) via belt
The plant runs three circular GV’s with up-draught ventilation, each GV holding one batch. Temperature control is maintained through a refrigerated cooling
system with a warm air recirculation facility. Germination duration is 4 days
After germination the malt is transferred to the kilning stage. Kiln is indirectly fired by anox natural gas burners and are strictly monitored and controlled
by a central control system. Usual kilning time is 20-24 hours. Warm air recirculation is incorporated during the kilning cycle and the kilning program
can be dictated by air-off RH reading displayed on the central control system.
