Summary

THE USEFULNESS OF THE PROGRAM HAS BEEN CHECKED BY MAKING MODEL EXPERIMENTS. MEASUREMENTS HAVE BEEN CARRIED OUT AND CALCULATIONS HAVE BEEN MADE BOTH FOR A SIMPLE AND A COMPOSITE STACK OF BOXES UNDER WELL CONTROLLED CONDITIONS. THE COURSE OF TEMPERATURE IN SLAUGHTERED PIGS DURING COOLING, TRANSPORT AND STORAGE HAS BEEN ALSO CALCULATED FOR A NUMBER OF CASES IN WHICH THE DURATION AND THE TEMPERATURE OF THE VARIOUS PHASES HAVE BEEN VARIED. PRIOR TO MAKING THESE CALCULATIONS A COMPARISON HAS BEEN MADE TO VERIFY THE MODEL DESIGN AND THE INPUT DATA OF THE PROGRAM. IN THE CASES CONSIDERED, IN WHICH COOLING OCCURS ALSO DURING TRANSPORT, THE COOLING TIME OF THE PIGS REMAIN WELL WITHIN TWENTY HOURS, PROVIDED THE CALCULATED, REQUIRED COOLING CAPACITY FOR EACH PHASE IS AVAILABLE IN PRACTICE. THE CALCULATED COOLING CAPACITY REQUIRED FOR TRANSPORT AND STORAGE IS IN THE SAME ORDER OF MAGNITUDE IN PRACTICE. MAKING CALCULATIONS FOR THE ENTIRE COLD CHAIN FOR A TS AND ASCERTAINING THE EFFECT OF MEASURES FOR IMPROVEMENT IS ONE OF THE APPLICATIONS.
