Maximum Hygrostress Response Charts for Drying or Hydrating Elastic, Cylindrical Food with Infinite Biot Number.

Abstract

Charts were prepared for estimating local maxima or minima of dimensionless, principal stresses of axial, radial, and tangential orientations formed in an elastic, cylindrical food during a drying or hydrating process. For this, analytical solutions derived previously were used. These charts showed that tangential stresses were the most critical for stress cracking during drying processes and radial stresses for hydrating processes. Sample applications of the charts were presented for adjusting process conditions to prevent stress cracking.
