Abstract

Cooking basket (1) in the form of a wire mesh cage (5, 6, 7) includes rack (2) which supports perforated former assemblies (3). Basket (1) is used in a cooking process which includes the steps of folding a flour or corn tortilla into a cone shape; placing the tortilla into an outer former; inserting a floating inner former into the tortilla to create a former assembly (3); inserting assemblies (3) into basket (1) and submerging basket (1) into preheated cooking fluid. During cooking, a fluid film develops between each of the formers and the respective tortilla surface, and the inner formers will float a predetermined distance above th outer formers. This results in faster cooking since both surfaces of the tortilla contact the cooking fluid and the cooked tortilla has a consistent thickness.

Description

A COOKING PROCESS AND APPARATUS
TECHNICAL FIELD This invention relates to cooking processes and apparatus, and has particular relevance to apparatus for cooking edible cones. BACKGROUND ART
United States Patent No. 3424076 describes methods and apparatus for cooking a cone-shaped tortilla product into a crisp stiff shell.
United States Patent No. 5,009,902 also describes a fried and crisp taco-shell made from tortilla and a method of producing same. United States Patent No. 4,313,964 describes a further apparatus and method for cooking a dough and forming it into an edible cone- shaped container.
United States Patent No.4,313,965 describes a process and apparatus for forming ice-cream cones. In all of the above disclosures cones are formed using inner and outer conical shaped formers.
Where the cones are formed by cooking in fat such as in the processes discussed in the first three United States patents mentioned above a surprising amount of uplift is created by the cooking fat and this uplift needs to be countered. Various means of counteracting the uplift have been proposed.
Any solution for counteracting uplift during cooking should not compromise the efficiency of the process.
It is an object of the present invention to provide a cooking process and apparatus which will enable fast and efficient production of edible cone-shaped jackets which can be used to serve a wide variety of food fillings.
Further objects and advantages of the present invention will become apparent from the ensuing description which is given by way of example.
DISCLOSURE OF INVENTION According to the present invention there is provided a process for cooking of a flour or corn tortilla comprising the steps of
(a) folding the flour or com tortilla into a cone-shaped configuration,
(b) placing the flour or com tortilla in a first cone-shaped metal former,
(c) inserting a second cone-shaped metal former into the flour or com tortilla to form an assembly,
(d) inserting the assembly in a support rack housed within a cooking basket having a closure means, (e) submerging the cooking basket into a pre-heated cooking fluid to fry the flour or com tortilla, characterised in that the sleeve is able to float within the cooking fluid and that the distance that the second cone shaped sleeve rises in the cooking fluid and thus the thickness of the cooked flour or corn tortilla is determined by a pre-determined spacing between the sleeve and the lid of the basket, The support rack is able removable from the basket. The support rack provides a plurality of support positions for the assemblies. The support rack is suspended from the sidewalls of the cooking basket.
According to a further aspect of the present Invention there is provided a cooking apparatus comprising;
(a) a cooking basket having closure means, (b) a plurality of sets of cone-shaped formers,
(c) a rack which provides support for sets of the cone-shaped formers within the basket, and
(d) support means for supporting the racks within the basket at a predetermined distance below the closure means of the basket.
The rack is removable from the basket.
The sets of cone-shaped formers each comprise as outer former with apertured walls and an inner former with planar walls.
The inner cone of each set of formers is spaced from the lid of the basket by approximately 30 millimeters.
BRIEF DESCRIPTION OF THE DRAWINGS. Aspects of the present invention will now be described with reference to the accompanying drawings in which;
Fiαurel is a side view of a cooking apparatus according to the present invention, and
Figures 2. 3 & 4 are end, plan and side views of the basket of the apparatus of Figure 1 , and
Figure 4a is an enlarged view of a closure lid catch according to the present invention, and
Figures 5 & 6 are plan and side views of a rack for the apparatus of Figure 1 , and Figures 7. 7a. 8 and 8a are side and plan views of cone-shaped formers for the apparatus of Figure 1, and
Figure 9 is a diagrammatic drawing of the relative positions of the cone-shaped formers of Figures 7 to 8a and a closed lid of the basket during cooking. With respect to figures 1 to 4a of the drawings the apparatus of the present invention comprises a cooking basket and closure means generally indicated by arrow 1, a rack generally indicated by arrow 2 which is adapted for placement within the basket which provides support for formers 3. The basket 1 is generally in the form of a wire cage having sidewalls 5, endwalls 6, a bottom wall 7 and a closure lid generally indicated by arrow 8.
The sidewalls 5 may taper slightly towards the bottom wall 7. The side, end and bottom walls can be constructed from solid metal bars and metal mesh 9. The basket 1 which includes closure lid 8 which comprises two rectangular bar frames 11 and a handle 12. The closure lid 8 is hinged to a top rail 5a of a sidewall 5. The closure lid 8 is able to be tilted into an open position as shown in figure 2, its travel being limited by stops 14 which extend from a sidewall 5 of the basket adjacent the hinge point of the lid 8. The handle 12 is pivotably mounted with respect to frame 11 as is best exemplified by figure 4a.
A hinge mounting 12a allows a catch 12b at the end of the handle 12 to be engaged and disengaged with a rail 14a of the basket. The catch 12b secures the lid in position during cooking. The catch is engaged with or disengaged from the rail 14a by tilting the handle 12.
Figures 5 to 9 of the drawings illustrate in more detail the rack 2 and formers 3.
The formers 3 (Figures 7 to 8) are provided in sets each comprising an inner former 15 and a complimentary outer former 16.
The inner and outer formers 15, 16 are truncated cones spun from relatively thin (approximately 0.9 millimeters thick) food grade aluminium.
The outer formers 16 are slightly deeper than the inner formers
15. The outer formers 16 are provided with a plurality of apertures
17 in the walls thereof.
By contrast the walls of the inner formers 15 are planar. The rack 3 is illustrated by Figures 5 and 6. For convenience of manufacture the rack 2 can be stamped from a single piece of metal.
The rack 2 comprises a cradle 18, two opposed L-shaped limbs 19, and handgrips 20.
The L-shaped limbs 19 each provide a rest for the rack 2 on the top of opposed end walls 6 of the basket 1 and thus set a predetermined positions for the cradle 18 within the basket.
The outer formers 16 sit in complementary apertures 21 in the cradle 18 and are welded in position. As is best exemplified by Figure 9 once the formers are loaded in the cradle 18 and the rack is positioned in the basket 1 with the closure lid 8 down the top edges of the inner formers 15 are set at a predetermined distance "S" from the lid. The distance "S" is important as it determines the extent to which the inner formers 15 can "float" during cooking, and thus the maximum thickness of the walls of cooked cones is so determined.
The cooking process of the present invention comprises the steps of folding a flour or com tortilla 22 into a cone-shaped configuration, placing the flour or com tortilla into the apertured outer formers 16, inserting the inner formers 15 into the flour or com tortilla to form an assembly, closing and securing the closure lid 8 and submerging the cooking basket and rack into a pre-heated cooking fluid (not shown).
As the flour or com tortilla 22 is cooking the cooking fluid will create a film between the outer surfaces of the flour or corn tortilla and a film the outer former 16 and the cooking fluid will also form a film between the outer surface of the inner former 15 and the inner surface of the shaped flour or corn tortilla and the inner formers will rise the distance S until contact is made between the top edges thereof and the overlying closure lid 8. The thickness of the cooked product is thus determined by the spacing.
After cooking the combined rack and support are removed and the unit placed on a cooling rack (not shown) which is specifically designed to provide support clear of a work surface.
During cooking uplift forces are transferred to the lid 8 as a result of the inner formers 15 rising and the uplift forces are resisted by the catch 12b of the handle 12 and its engagement with a top rail 14a of the basket 1.
By contrast with the prior art devices and methods the present invention has a number of distinct advantages in that;
(a) faster and more efficient cooking is achieved by allowing a fat film to be readily created between both inner surfaces of the outer former and the outer former surfaces of the inner former and the product, (b) Consistent wall thickness of the cooked product is readily achieved,
(c) The apparatus can be produced at a relatively low cost and readily set up for constant high volume production.
Aspects of the present invention have been described by way of example only and it will be appreciated that modifications and additions thereto may be made without departing from the scope thereof, as defined in the appended claims.
