Burnley Maltings is a traditionally formatted Malthouse with separate steeping vessels and four Saladin Boxes feeding direct fired natural gas Pressure Kilns, producing mostly pale barley malt with some wheat malt production.
It is a highly efficient twenty-four hour, seven day a week, continuous operation. Annual production is approximately 23,000 tonnes of malt.
Food Premise Registered.

Strict control is applied to all incoming barley. Raw material quality control regarding 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 74 Tonne with a 32hr maximum steeping cycle.
Current steeping procedure incorporates 4 x 37 Tonne capacity conical steeping tanks with multiple immersion steeping, aeration and CO2 extraction.
Steeping program and steep temperatures are monitored continuously.
Steeped grain is wet transferred to the germination boxes
The plant runs four saladin boxes with up-draught ventilation, each box holding one batch. Temperature control is maintained through a refrigerated cooling system with a warm air recirculation facility. Box germination duration is 4 days
After germination the malt is transferred to the kilning stage. Here one batch is split between two pressure kilns. Kilns are directly fired by Low NOx natural gas burners and are strictly monitored and controlled by digital programmable controllers. Usual kilning time is 18-20 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
