DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a method and apparatus for producing braided baked products. The invention is particularly useful for making challahs or rolls, and is therefore described below with respect to this application.
Challah is a loaf of yeast-leavened bread, usually braided, and tradionally eaten by Jews on the Sabbath, holidays and ceremonial occasions. At the present time, braiding the dough is generally done manually, either by shaping a strip of the dough into the digit "8", or by interweaving a plurality of strips, usually four, of the dough into a braid. Manually forming the braids when making challahs, rolls or other braided baked products, is not only a relatively slow, tedious and costly process, but is also a non-hygienic process because of the human contact with the dough. While attempts have been made to mechanize the production of challah and other braided baked products, insofar as I am aware none of the proposed mechanisation techniques has been found to be satisfactory, and therefore to this day challahs and other braided baked products are generally still produced manually.
An object of the present invention is to provide a method and also an apparatus for producing braided baked products, such as challahs and rolls.
According to one aspect of the present invention, there is provided a method of producing a braided baked product from dough, comprising: feeding the dough through a die head having at least three relatively-movable die members each formed with an orifice feeding a strip of the dough; moving the die members relative to each other during the feeding of the dough to cause the strips to interweave; and baking the interwoven strips to produce the braided baked product.
According to further features in the described preferred embodiment, the die members are plates of the same external shape and are movable relative to each other by at least two rotatable drive members. Each die member is formed on its outer circumference with at least two cavities of a shape complementary to that of the die plates for receiving and moving the die plates during the rotation of the drive member. The drive members are in the form of equal-diameter discs having parallel axes of rotation spaced from each other a distance such that each die plate is receivable in either cavity of each drive disc so as to be moved by the rotation of the drive disc.
The invention also provides apparatus for producing braided baked products in accordance with the above method.
As will be described more particularly below, the method and apparatus of the present invention enable braided baked products, such as challahs or rolls, to be produced in a mechanized continuous manner eliminating, or minimizing, human contact with the dough such that the production of the braided baked product enables a substantially savings to be made in labor and also provides better hygienic conditions.
Further features and advantages of the invention will be apparent from the description below.
The invention is herein described, by way of example only, with reference to the accompanying drawings, wherein:
FIG. 1 diagrammatically illustrates one form of apparatus constructed in accordance with the present invention;
FIG. 2 diagrammatically illustrates the extruder head in the extrusion apparatus of FIG. 1;
FIG. 3 diagrammatically illustrates various stages in the movement of the die members in the extrusion head of FIG. 2 for producing a braided baked product;
FIG. 4 illustrates another form of drive for driving the die members in the extrusion apparatus of FIG. 1; and
FIG. 5 illustrates another form of screw feeder that may be used in the extrusion apparatus of FIG. 1.
The apparatus illustrated in the drawings is an extrusion apparatus particularly useful for producing braided baked products, such as challahs or rolls, in a continuous mechanized fashion. The apparatus includes an extruder, generally designated 2, having a hopper 3 for receiving the dough to be used in making the baked product, and a screw feeder 4 for feeding the dou
