Control of Heating Chamber on Packaging Machine A1 TFA
(2006) In MSc ThesesDepartment of Automatic Control
- Abstract
- On the packaging machine Tetra Pak A1 a heating box is used to sterilize the packaging material. This is done by passing the material through a bath of hydrogen peroxide and then vaporizing the liquid in the heating box. The heating is done by three resistive elements that pass their energy by convection and radiation to the packaging material. Problems occur due to temperature variations on the web of the packaging material. During normal production the temperature variations are small and acceptable. At starts and stops, overshoots cause material damages and undershoot results in peroxide residues forcing disposal of packages. This master's thesis proposes how to optimize the control of the temperature. The control will be divided into... (More)

This master's thesis proposes how to optimize the control of the temperature. The control will be divided into three stages; start, running and stop. Different conditions during these stages will force the control logic into three different implementations. (Less)
