Abstract

Mould of an array of moulds for making bread rolls comprises two parts, one of which contains a cavity 7 and the other of which contains a cap 3 with a former 4 extending therefrom. In use, a quantity of dough is placed in the cavity 7 and the cap 3 put over the open end with the former 4 extending into the cavity 7. The dough is then allowed to prove around the former, and the entire mould is then baked in an oven. The bread rolls made in this way are shaped according to the shape of the cavity and are penetrated by a hole. Since the hole is baked into the roll the entire interior surface of the hole, as well as the entire exterior of the roll, are crusted. <IMAGE>

Description

A MOULD FOR BREAD ROLLS This invention relates to bread rolls and to a method and apparatus for making bread rolls.

Bread rolls are made in many shapes and sizes.

Commonly, the raw bread dough is hand or machine formed to a predetermined shape before being placed on a baking tray and baked in an oven. Polls formed in this manner must usually be cut or torn to provide a pocket or the like in which a filling can be placed.

The need to cut or tear the roll can be disadvantageous particularly where rapid production of many filled rolls is desired and where the filling includes a sauce. In this regard cutting or tearing involves an additional preparation step and the filling can easily escape from the cut or tear particularly in the case of a sauce. These problems are especially prevalent in the case of hot dogs made by placing a frankfurt and sauce in a bread roll.

Fast foods such as hot dogs are often eaten whilst standing or "on the run" and this can be difficult if the filling i-s prone to escape from the cut or tear in the roll so that both hands are required to eat the food.

In addition, the cut or tear in the rolls made for fillings exposes a fresh bread surface which readily absorbs sauce type fillings so the roll can become soggy.

It is an object of this invention to provide a bread roll and a method and apparatus for making a bread roll which will overcome, or at least ameliorate some of the abovementioned disadvantages.

According to one aspect this invention consists in a two part mould for making bread rolls, said mould comprising a first part including a cap and an elongate former extending from within said cap; and a second part having a cavity formed therein to surround said former and to co-operate with said cap to define a substantially closed mould for the bread roll when the first and second parts are put together.

Preferably the mould is formed as two tray like elements, a top tray having a plurality of cap and elongate former combinations comprising the first parts, and a base tray having a corresponding plurality of cavities formed therein comprising the second parts, whereby the top tray can be placed on the base tray to form a plurality of closed moulds.

For preference the cavities have a generally parabolic longitudinal cross-section resulting in a cone like cavity. It will be apparent that this facilitates easy removal of the rolls after baking.

Similarly the cap is preferably concave so as to form one rounded end on the bread roll and aid in easy removal of the mould.

In the preferred embodiment the elongate former is of generally circular cross-section and tapers towards its free end to facilitate easy removal from the baked roll.

According to a second aspect this invention consists in a method of: making a bread roll in a two part mould as defined above said method comprising the steps of: placing a quantity of bread dough in said cavity in the second part; putting the first and second parts together to form the mould; allowing the dough to rise or prove around the former; and baking the roll whilst it is in the mould.

This invention also includes within its scope an elongate bread roll having a blind cavity therein which extends along substantially the full length of the roll.

For preference the cavity is frusto-conical and extends from one end of the roll.

It will be apparent that a bread roll formed according to this invention, by being provided with a hollow cavity extending from one end thereof, eliminates the need to cut or tear the roll to insert a filling.

This is particularly advantageous when making hot dogs since the cavity can be substantially cylindrical and slightly -larger than the frankfurts used in the hot dog.

This allows the frankfurt and a quantity of sauce to simply be placed in the form a finished hot dog.

Also, because the cavity is formed during proving and before the roll is baked a crust is formed over the entire exterior of the roll and the interior of the cavity, and this crust at least reduces the penetration of sauces into the roll; such penetration would otherwise tend to make the roll prematurely soggy.

Further, because the filling is placed in a blind cavity it cannot escape easily and the roll can be eaten using one hand like an ice-cream cone without danger of losing the filling.

A preferred embodiment of the invention will be more particularly described, by way of example, with reference to the accompanying drawings wherein: Figure 1 is a schematic inverted plan view of a first part or top tray of a two part mould according to an embodiment of the invention.

Figure 2 is a schematic plan view of a second part or base tray of a two part mould according to an embodiment of the invention.

Figure 3 shows sections along the lines III-III of Figures 1 and 2 when the top tray and base tray are respectively positioned to form the mould.

Referring to the drawings the two part mould for making a bread roll comprises a first part or top tray 1 and a second part or base tray 2. The trays are preferably cast from aluminium.

The top tray 1 is rectangular and includes a plurality of concave caps 3 in a uniform array. An elongate former 4 of circular cross-section extends from within each cap 3 and is tapered to a lesser diameter toward its free end.

The caps located at the four corners of the tray have inspection holes 5 in their outer quadrants to permit the extent of proving of the dough to be ascertained. Placing inspection holes at each corner of the tray allows for speedy testing of each tray no matter how the trays are arranged or stacked.

The base tray 2 is also generally rectangular and supports a plurality of blind tubes 6 of generally parabolic longitudinal cross-section defining cone-like cavities 7. The tubes 6 are cast integrally with the tray and after casting have small holes 8 drilled through their ends to allow easier release of the baked rolls.

Gravity casting is the preferred way of manufacturing the trays from aluminium since this results in a slightly roughened surface which has been found to support a non-stick coating most effectively. Pressure casting or fabrication from sheet and spun aluminium are also possible; it should also be appreciated thåt the trays could be made from other materials.

The top tray 1 and base tray 2 fit together as shown in figure 3 such that respective formers 4 are enclosed within cavities 7 and the respective caps 3 co-operate with cavities 7 to define a substantially closed mould.

A channel 9 is provided around the edge of one tray and a flange 10 around the edge of the other, and when the trays are brought together flange 10 locates in channel 9 ensuring that the trays come together with the correct configuration. The trays may conveniently be held together by a locking device 11, the two halves of which may be located more or less centrally in the top and base tray respectively.

The blind tubes 6 of base tray 2 are preferably cast with bracing 12 (not shown in detail) between them to prevent damage during use, and the bracing provides a convenient running surface 13 on which the trays may be transported on conveyors without risk of damage to the tubes. The bracing also serves to conduct heat to the cavity very efficiently, and also assists rapid cooling of the trays after baking. The overall size and height of the trays is preferably limited to the size of conventional baking ovens.

Using the two part mould described and shown, bread rolls are made by placing a small quantity, usually a ball, of bread dough in the bottom of each cavity 7 of base tray 2. The top tray 1 and bottom tray 2 are put together to form the mould by positioning the top tray on the base tray in the manner shown in figure 3. The bread dough is allowed to rise or prove around the former preferably so as to substantially fill the mould. The extent to which the dough within any particular mould has risen may conveniently be tested through one of the inspection holes 5 either by eye or feel. Finally, the roll is baked whilst in the mould by placing the whole mould in an oven.

After baking the rolls are removed from the mould.

The concave cap and tapered former aid in easy removal from the top tray, and the cone-like shape of the cavity in the base tray and the drilled holes similarly assist in separation.

The bread rolls produced in the manner described are shaped like elongate cones having an elongate conical aperture into which hot dogs or other savoury foods accompanied by a sauce may be inserted.

Alternatively a sweet filling may be used, but in this case a sweet bread dough is employed. The method preferably employs any grain, white or brown dough, but not pastry or sponge or cake mixtures which may not rise satisfactorily.

Although only one embodiment of the invention has been described it will be apparent that modifications thereto may be made without departing from the scope of the invention. For example, the formers need not be tubular and can be formed as substantially planar members so as to provide a thin bread cavity suitable to receive sliced fillings for example. In addition the trays can be modified to mould any desired number of bread rolls.
