In a vegetable canning factory, canned food boxes containing 800 g of product are heat treated in an autoclave. Two food engineers working at the factory are planning to increase the production capacity by changing the geometry of the canned food containers. Production capacity is proportional to the residence time in the autoclave of two designs with the same volume. Engineers' designs are given below. Which is the most appropriate recommendation show it with calculations.

Engineer 2: Cylinder, height / diameter ratio: 2/1

Engineer 2: Rectangular prism, aspect ratio 1x1x2

Canned vegetables: Starting temperature:20C Sterilization temperature:100C Autoclave temperature:120C Sterilization time:4 min Conduction heat transfer coefficient:0.6 J/msC Convective heat transfer coefficient on the surface:10000 J / m² sC S Specific heat capacity: 4 kJ/kgC Density: 980 kg/m³
