An industrial shed (9 x 12m) with concrete flooring and roller door access was constructed at ACRI in November 1998. The shed was sited in close proximity to other sample processing buildings. A drying room was constructed within the shed using insulation panelling with single door access. This room was then fitted with shelving and a mobile dehumidification unit installed. This unit efficiently removes water vapour from the atmosphere within the room using refrigeration technology. The writ can remove in excess of 40 L of condensed water vapour- each day. This is sufficient to dry plant material on fully laden shelves within 2-3 days. The drying period is similar to the existing dehydrators, but the new facility uses a fraction of the electricity consumed by the older dehydrators. The unit operates at about 50 Degrees C compared with the older units which operate at 80 degreesC. Thee unit was operating by mid-January 1999, prior to the busiest part of the cotton season. It was in constant use until mid-winter 1999.
