COMPREHENSIVE 3D»1D MODELER for 3 pieces packaging
Derive the most appropriated 1D approximation of mass transfer in a 3D food+packaging for compliance testing (3D rendering is also performed).


Cartesian and cylindrical geometries

5 volumes to define

  • internal volume
  • food product
  • packaging top
  • packaging walls
  • packaging bottom
length units
use res to change the resolution
res. rendering
use [azimuth elevation] to change the 3D view

Internal volume
=food volume+head space
Define the internal volume of your packaging
along X
(or diameter)
along Y
ignored
if cyclindrical
along Z
units units units
 
To work with mass/mass concentrations, the density of headspace (e.g. liquid surrounding the food) is required.
relative density of headspace
arbitrary units (e.g g/cm³)
Food volume
=what is consumed
Several scenarios will be calculated for the dilution factor (including the heaspace or not)
Define the simplified geometry of your food
(cannot exceed the dimensions of the internal volume)
along X
(or diameter)
along Y
ignored
if cyclindrical
along Z
units units units
 
To work with mass/mass concentrations, the density of headspace
(e.g. liquid surrounding the food) is required.

3 pieces packaging
=top+walls+bottom

Only thicknesses (T) are required, the other dimensions are automatically calculated.
Mass balance and thermodynamical considerations are added to help the user to identify "worst case" scenarios.
Initial concentrations (aribitrary units) and partition coefficients(K_FP with P={top,wall,bottom}) are only required for mass balance and thermodynamical analysis (advanced use). K_FP are based on mass/mass concentrations.
