Dryers designed to remove moisture from forensic evidence (e.g., cloth, shoes, underwear, masks, towels) using forced air to ensure that the samples are dry. These dryers typically consist of a large (typically from 55 to 440 cubic dm [2 to 16 cubic feet]), freestanding cabinet-like enclosure with a forced-air source and appropriate corrosion-proof holders and shelves for evidence; some dryers include electric heating elements. The devices also include air intake and exhaustion filters (e.g., HEPA), carbon filters, time and temperature controls, and alarms. Forensic evidence dryers are intended to dry wet evidence (e.g., of sexual assault) before further processing, reducing the risk of cross-contamination.
