BAKING APPARATUS

摘要

A process and apparatus are disclosed for making a hollow baked product which is coated on at least part of tis inside surface and, if desired, is filled at least in part. The hollow baked product comprises a tubular body, which has been formed by winding a baked strip with overlapping convolutions and consists particularly of a wafer strip. In accordance with the invention, edible materials in a pasty or liquid or spreadable state and in the form of at least one coherent stream are applied to the inside surface of the tubular body through openings formed in the forward end face of the mandrel or behind the mandrel in the direction of conveyance and/or are caused to emerge through openings formed in the peripheral surface of the mandrel. The edible material which has reached the inside surface of the tubular body may be spread at least over part of said inside surface. A particulate solid material which is to be applied to the coating and/or a filling material may be introduced into the tubular body through the mandrel and, if desired, through an extension of the mandrel. Individual pieces severed from the tubular body will constitute internally coated, hollow baked products, which may contain a filling and which can be immediately packaged.
