Tunnel ovens require a full set of trials in order to calibrate them for the PentaCake usages. The cake shape and volume are affected by mainly the following oven parameters: (1) Temperature in each zone in the oven, (2) Up/down heating balance in each zone, (3) Level of the chimneys opening in each zone, (4) Baking time. The cracks can be minimized mainly by the following adjustments in the baking: (1) Baking in a fully loaded oven, in order to ensure that the oven is humid, (2) Slightly closing the oven chimneys in order to make the oven atmosphere more humid, (3) Reducing the baking temperature, mainly in the entrance zone, and elongating the baking time accordingly, (4) In some cases, slightly increasing the bottom heat and decreasing the upper heat.
