Abstract
An experimental equipment for dry-heat inactivation of bacterial spores in an open system using Infrared (IR) radiation for energy transfer was developed. The dry-heat-inactivation kinetics forBacillus subtilis ATCC 6633 spores were studied in the temperature range of 120–180C. The z value (z=23C) was constant in the temperature range investigated. The advantages offered by using IR radiation in sterilization systems are pointed out.Keywords
