Abstract

A process for manufacturing hollow, thin-walled pastry articles, particularly cone shaped waffles, wherein a kneadable, firm dough body is conveyed to a plurality of baking molds of a cone baking apparatus, each baking mold consisting of a matrix and a patrix, the dough body being delivered into each matrix. The patrix or core of the mold is lowered into the matrix to distribute the dough body over the matrix wall, and is raised again to allow the escape of air and vapor developed by the dough body during baking. The lowering and raising operation of the patrix core is repeated several times and the patrix core remains in the lowered and raised position at varying intervals. The patrix is finally locked on the mold and after final baking the mold is opened and the finished hollow, cone shaped waffle is released.

Claims

1. A process for manufacturing hollow, thin-walled pastry articles, comprising the steps of:

preparing a mixture of flour and sugar with at least about 400 grams of sugar per kilogram of flour;

adding to the mixture an amount of water only sufficient to make a kneadable, firm, shape-holding waffle dough;

forming a discrete dough body in a definite shape from the prepared waffle dough;

placing the shaped body of waffle dough on one part of an open baking mold having a hollow part at least partially closed at one end and a core part received in the hollow part;

bringing the parts of the baking mold together to close the mold around the dough to define the shape of the article;

baking the dough with the mold closed;

allowing vapor to escape from the mold at least intermittently while continuing to bake the dough until the article is formed and then;

opening the mold and removing the article.

2. The process of claim 1, wherein the step of allowing vapor to escape is accomplished by intermittently separating the parts of the mold sufficiently to allow vapor to escape from the mold.

3. The process of claim 2, wherein the step of intermittently separating is accomplished by withdrawing the core part for a first selected interval of time and then reclosing the mold and subsequently repeatedly withdrawing the core part for intervals of time briefer than the first and reclosing the mold following each withdrawal of the core part.

4. The process of claim 1, wherein said dough body is shaped as a rounded mass flattened on one side and is placed flat-side up in the hollow part of the baking mold.

5. The process of claim 1, wherein the dough body is shaped like a hemisphere and placed in the hollow part of the mold with its spherical side toward the at least partially closed end of the hollow part.

6. The process of claim 1, wherein the amount of water added is no more than about 0.6 liters per kilogram of flour before baking.

7. The process of claim 1, wherein the amount of water added is about 0.4 to about 0.6 liters per kilogram of flour before baking.

8. The process of claim 1, wherein vapor is allowed to escape during baking through the at least partially closed end of the hollow part of the mold to insure complete filling of the mold with said waffle dough.
