Abstract(s)
In a case study on white beans, the e ect of rotation on the statistical variability of heat penetration parameters and on the nonuniformity
of lethality in industrial-scale retort processing was investigated. In addition, the in¯uence of process time on the nonuniformity
of lethality was evaluated. No clear relation between the non-uniformity of the heating parameters and the rotational
speed was observed. Rotation seemed to in¯uence process lethality variability throughout the retort by its e ect on non-uniformity
in heating characteristics and in retort temperature. Absolute non-uniformity (i.e. standard deviation) increased with increasing
holding time, whereas relative non-uniformity (i.e. coe cient of variation) decreased as holding time increases
