Malt handling The involvement of this team has led to an operation which has been fully assessed for hazards, with pipe work labelling, tank identification and asset tagging being delivered by those fully involved in the future operation of the distillery. A management of change process has been delivered to ensure any future changes to plant, control or operations are fully assessed with all relevant processes and drawings updated to reflect these changes. 2016 production activities have continued to deliver fine tuning and optimisation of process operations. Raw materials and utilities Thermal energy is provided by the original Cochran Thermax and the newly-installed Byworth boiler each producing 11.0 tonnes steam per hour at around 8.0 bar pressure. Each boiler is fitted with an economiser recovering waste heat from the flue gases prior to discharge through a new 35ft chimney.
