Kiln
The kiln is designed to mimic a full-scale kiln. The kiln is a four unit system where each unit can be programmed and run independently of the other three units i.e. each kiln can run independent programs using different time, temperature, airflow and recirculation values. Each unit can hold either 4 x 500 g rectangular sample containers or a single bulk sample container holding up to 8 kilograms. These samples are not turned. Each kiln includes a programmable recirculation valve such that during kilning it is possible to vary how much of the air is fed back to the fan intake. In this way the kiln can, if required, produce fully stewed malt. Programming the kiln is by a Windows based program running on a PC. The program allows for up to 15 periods, the time for each period is programmable between 1 and 48 hours, and the temperature for each period is programmable between 30 degrees C and 110 degrees C at 1-degree intervals. Airflow and air recirculation are also programmable via the PC. Varying the amount of recirculated air effects humidity control in the kiln. We have developed a range of miniature air valves that allow us to vary the air from fully exhausted to fully recirculated, such that if required the kiln can produce crystal type malts as well as very gently dried distilling malts, with all the intermediary types in between. Throughout kilning, the following parameters are continuously monitored and logged; air-on temperature, air-off temperature, humidity and airflow.
Our latest kiln design allows for the kilning of multiple small samples or single bulk samples up to 8 kilograms of as-is weight barley. The malt beds are static and because the air is forced through the grain rather than around it, as in other machines, representative kilning is achieved.
The kiln requires the following services:
230VAC single phase supply at 13 Amps.
Spent air outlet.
