Steam cooking is indicated where a boiled effect is required and it has the advantage of leaving the nutritional content of the food unaltered the vitamins and flavour of the food are conserved the outer appearance the colour is conserved no lumps or air bubbles are formed and the surface does not break up and the weight is conserved as no liquids are lost from the food during cooking 3 5 2 Convection cooking dry heat The heating elements heat the dry air inside the cooking chamber This heated air is evenly distributed by the high speed of the fans This gives an even temperature throughout the cooking chamber and even cooking even when the oven is full This means that different types of food can be cooked on the various shelves as long as they need the same cooking temperature without flavours and smells being mixed together The cooking chamber temperature can be set between 50 C and 270 C Besides evenly browning the food without having to turn it convection cooking can be used to cook au gratin and is particularly convenient for rapid defreezing for sterilising preserves and drying mushrooms and fruit 3 5 3 Convection steam cooking dry heat moist heat This type of cooking exploits the combination of dry and moist heat The heat is dosed by the climate regulation system which can divide in percentage the production of steam and the production of dry heat drying the cooking chamber optimising the cooking clim
