Abstract
Abstract A foodstuff is placed on a rack in a food-treatment apparatus having a chamber. Air in the chamber is drawn in by a blower positioned adjacent a rear wall and is displaced outwardly along the chamber walls past heaters to again reach the foodstuff. The blower is surrounded by means, e.g. a hood, for protecting the oven from grease or fat spatter, and the bottom of the chamber is provided with a trough for collecting fat dripping from the hood, the racks, baffle plates and other surfaces in the oven.
