Development of Air Impingement Technology and Data Acquisition System for Bread Baking Study

An experimental impinging jet oven with flexiblegeometry and variable jet velocity and temperature wasdeveloped to investigate and optimize the Iranian breadbaking using a novel heating mode: impingement. Thisoven was equipped to online data-acquisition system.The fully transient nature of the baking process makesthe simultaneous measurement of the baking parametersnecessary, which was neglected at previous studies onbread baking in Iran. Thus, the required hardware andsoftware, written by Borland Delphi®, were developedto measure and record the data throughout the bakingexperiences. Weight and temperature of the bread werecontinuously measured through appropriate sensors. Thecapability of the oven control instruments to diminishthe fluctuations of the impinging jet velocity andtemperature resulted in test repeatability and moreexperimental accuracy.
