A new meat product similar to salami will be produced and then pasteurized by heat treatment. It is possible to produce the meat product in three different geometries (sphere, cylinder and rectangular) with equal volume. Which geometry should be preferred to reach the target pasteurization temperature (90 ° C) in the minimum time? Starting temperature: 20 ° C Autoclave temperature: 110 ° C Conduction heat transfer coefficient: 0.45 J / m s ° C Convective heat transfer coefficient on the surface: 540 J / m2 s ° C Specific heat capacity: 3200 J / kg ° C Density: 1200 kg / m3 Product weight: 600 g Geometrical shapes: a) Cylinder, Diameter / height ratio: 1/2 b) Rectangular prism: Aspect / height / height ratio: 1x1x2 c) Globe
