Manufacturing method and manufacturing apparatus for Baumkuchen
There are provided a manufacturing method and a manufacturing apparatus for Baumkuchen for easily and properly suppressing shape distortion of the Baumkuchen caused in a manufacturing process thereof. In manufacturing the Baumkuchen by alternately repeating application of batter around the whole outer circumference of a spit and baking of the applied batter, the batter is scraped off outer circumferences of opposite end portions of the spit before baking only in early stage of manufacturing until the number of repetitions reaches a specified value. As a result, the number of cake layers formed at the opposite end portions of the Baumkuchen is reduced from that at the other portion and outside diameters of the opposite end portions are reduced from a normal outside diameter to thereby suppress partial increase in the outside diameter at the opposite end portions of the Baumkuchen caused by drooping of the batter at the end portions of the spit before baking.
1. A method for manufacturing a Baumkuchen having a uniform diameter throughout the length of the Baumkuchen, the method comprising:
rotating a spit having an outer circumference, a first end, a second end opposite the first end, a length extending from the first end to the second end and a central portion between the first and second end;
in a first applying operation, applying batter around the entire outer circumference and the length of the rotating spit;
carrying out a first scraping operation by completely scraping off the batter, from the first applying operation, from the outer circumference for a first distance extending from the first end of the rotating spit toward the central portion of the rotating spit, and from the second end of the rotating spit toward the central portion of the rotating spit while retaining batter for a length extending between the first and second end of the rotating spit; and then
baking the batter in a first baking operation while rotating the spit;
in a second applying operation, further applying batter around the entire outer circumference and the entire length of the rotating spit and on the baked batter from the first baking operation;
carrying out a second scraping operation by completely scraping off batter, from the second applying operation, from the outer circumference of the rotating spit for a second distance that extends from the first end of the rotating spit toward the central portion of the rotating spit and from the second end of the rotating spit toward the central portion of the rotating spit, wherein the second distance is less than the first distance and only scrapes off portions of batter from the second applying operation; and then
baking the batter in a second baking operation while rotating the spit;
repeating the second applying operation, the second scraping operation and the second baking operation a specified number of times, wherein each repeated second scraping operation completely scrapes off batter from the rotating spit for a distance that is less than the distance of the previously applied second applying operation;
in a third applying operation, further applying batter around the entire outer circumference and the entire length of the rotating spit, and on batter previously baked from the second baking operations; and then
baking the batter in a third baking operation while rotating the spit;
repeating the third applying operation and the third baking operation until the resulting Baumkuchen has a plurality of layers in a region defined by a baked layer resulting from the first baking operation; and wherein the resulting Baumkuchen has a uniform diameter throughout the length of the Baumkuchen;
wherein the specified number of times the second applying, second scraping and second baking operation is repeated is obtained by performing the steps of,
producing a test Baumkuchen that has been produced only by applying batter to the entire spit, baking the batter and repeating the applying and baking steps to produce a test Baumkuchen having multiple layers; and
measuring a thickness of a central portion and a thickness of an end portion of said test Baumkuchen; and
dividing the difference between the thickness of the end portion and the thickness of the central portion of the test Baumkuchen, by the mean value of the thickness of one layer of the test Baumkuchen to thus obtain the number of times to repeat the second applying, scraping and baking operation.
2. The manufacturing method for Baumkuchen according to claim 1 , wherein the batter is scraped off by pushing a distal end of a flat scraper against a surface of the outer circumference of the spit.
