Abstract
A baking or roasting oven is provided with a transfer apparatus by which the pieces of edible material which is to be roasted, such as slices of white bread, soft wafers, etc., are fed into the oven and the roasted toasts are removed from the oven. The oven comprises an endless chain of hinged tongs, which can be opened and closed and are adapted to hold the pieces of edible material which are to be roasted. The chain of tongs moves in the oven in two superimposed planes. A transfer station is provided adjacent to the upper plane in which the upper course of the chain of tongs extends. The tongs move in an open position through that transfer station, which contains two sets of drums, which are closely spaced one behind the other in the direction of travel of the upper course of the chain of tongs and are disposed above the bottom plates of the open tongs of said upper course. The drums of the set consist of vacuum drums, which rotate at a surface speed that is equal to the speed of travel of the chain of tongs. The pieces of edible material which are to be roasted or which have been roasted are held on the shells of said drums as said pieces are transported by said drums.
