摘要: Abstract A model for predicting the dynamic product heat load and weight loss during beef chilling has been developed using finite difference method, in which irregular geometry is approximated by a combination of seven cylinders slabs. The was tested against data from 55 industrial trials covering wide range carcass size, fatness conditions. predicted removed first 2 h on average 12.6% higher than experimental value. after 20 0.0194 kg (0.00046%) Improvements accuracy would probably have arisen if slaughter floor chiller conditions had more accurately known. allows time-variable conditions, making it widely applicable to meat industrv applications.
