摘要：

A cascade thin film scraped surface heat exchanger, having sterilizer, regenerator and cooler sections was tested for thermal death kinetics of B. stearothermophilus spores in milk. A sterilizing effect of 6.15 was obtained at 152°:C for a holding time of 1.25 s. D values of 1.18, 0.75, 0.25 and 0.20 s were obtained for B. stearothermophilus at 143, 145, 150 and 152°C, respectively. the Z‐value obtained was 10.1°C. Copyright © 1990, Wiley Blackwell.
