Abstract

Horizontal shelf for supporting bread dough pieces in a bakery proving chamber and/or baking oven, is of the type which has a multi-trough assembly for dough pieces to lie in each trough. The shelf pref. slides into a trolley which can be rolled from a proving chamber to an oven. Trough assembly is formed from a sheet of mild steel fine wire mesh coated in paint which is resistant to a temp. of about 300 deg.C, e.g. an epoxy resin paint. The paint does not block the holes of the mesh. The concave face of each trough is pref. coated with a layer of silicone which does not block holes in the mesh. Shelves are cheaper, lighter in wt. and less subject to distortion than previous shelves in stainless steel and glass fibre.

Description

The present invention relates to dough supports for the production of bread.

We know that modern bread making uses fermentation cabinets in which the dough fermentation is blocked, then favored and large ovens, in particular rotary, with circulation of hot cooking gases.

To avoid as much as possible the operations of handling the dough pieces, trolleys arranged in shelves with removable shelves or supports are used, each of said supports being made of a bbti supporting a set of parallel elongated cells. Thus, after shaping the dough pieces, these are placed individually in the cells of said supports; who are next. set up in their respective slides.

The carts thus loaded with patterns are introduced into a fermentation cabinet and, after satisfactory fermentation of said dough pieces, are taken out of said cabinet, to be introduced into the oven with their loading, so that said dough pieces are cooked in the cells of said supports.

In known supports, all of the cells are formed by @@ stainless steel screen or a glass cloth. In the latter case, the glass fabric is impregnated with silicone so as to avoid the @ dherence of the patons on the bottom of their cells.

Such supports, because of the material of the cells, on the one hand are deformed and on the other hand are oneral.

 The object of the present invention is to remedy these drawbacks.

To this end, according to the invention, the support intended to support dough pieces during their cooking and / or their fermentation and constituted by a frame supporting a set of cells for receiving said dough pieces, is remarkable in that said set of cells is formed in a fine plain steel mesh, coated with a layer of paint. , such as an epoxy paint, resistant to a temperature of about 300 C and not closing the meshes of said mesh.

Thus, an inexpensive support is obtained, the set of alveoli of which is undeformable. Indeed, the epoxy paint stiffens the mesh cells, so that they keep their shape. However, this paint is flexible enough not to flake, in the case where, for example following an impact, a cell is locally deformed.

Preferably, at least the concavity of said cells is coated with a layer of silicone which does not block the meshes of the mesh. It has been noted that the epoxy paint constitutes an excellent support for the silicone, which adheres perfectly and securely to said paint.

In an advantageous embodiment, the mesh is made of wire of about 0.5 mm in diameter and has 4 to 8 meshes per linear cm.

Advantageously, in the case where said cells are elongated, parallel and connected to each other by fold lines, the frame supporting the set of cells consists of a frame formed by two sections of parallel tubes, rigidly connected to the one to the other-by a plurality of ~ transverse rods, on each of which rests the underside of one of said fold lines.

Preferably, the plurality of said transverse rods is arranged on the same side of the plane passing through the axes of the two sections of tubes. From place to place, the set of cells can be made integral with said transverse rods by welding points distributed along said fold lines. At the transverse ends of the frame, the grid of the set of cells is folded around the corresponding extreme transverse rod, to be fixed by welding under it.

Furthermore, it is advantageous to provide, at least, at the ends of said tube sections and on the side opposite to said rods, transverse bars welded under these at their ends.

Such bars can serve as rest pads and for sliding the support on its slides.

It will be noted that the choice of tubes to form two opposite sides to the frame is advantageous, because these tubes have little thermal inertia, so that they store little heat, during the cooking of the dough pieces and that they cool very quickly. after being taken out of the oven. There is therefore no risk of contact burns.

In addition, the section of said tubes is preferably circular, so that the cooked dough pieces can be easily removed from the cells by sliding on one of said tubes.

To produce the support according to the invention, the frame can be produced on the one hand, for example by welding sections of metal sections on the pipe sections and on the other hand the cell assembly by folding a mesh, for example to the press. Then, a set of cells is put in place and welded to the frame, after which the set is degreased, painted and optionally coated at least in part with a layer of silicone.

The figures of the appended drawing will make it clear how the invention can be implemented.
Figure 1 is a plan view of the dough support according to the invention.

FIG. 2 is a side view of the dough support of FIG. 1.

Figure 3 is an enlarged sectional view along line III III of Figure 1.

FIG. 4 illustrates the method of manufacturing the dough support according to the invention.

The dough support according to the invention, shown by these figures, comprises a frame 1, in the form of a frame, on which is mounted a set of cells 2.

The frame 1 is formed by two sections of parallel tubes 3 and 4 parallel and made integral with one another by a plurality of transverse rods 5, the ends of which are welded, respectively at 6 and 7, on said tubes 3 and 4, so that these are both on the same side of the plurality of said rods 5. In addition, at each of their ends, the tubes 3 and 4 are connected to each other by a rod transverse 5 ', located on the side of the rods 5 and providing a space 8 with the corresponding extreme rod 5 and by a transverse rod 9, disposed on the side opposite to the rods 5 and 5'.

The rods 5 ′ and 9 at one end are arranged in a plane orthogonal to the tubes 3 and 4 and connected to each other by welded spacers 10.

In the position of use, the dough support according to the invention rests by the rods 9 on the slides of a carriage and its face comprising the rods 5 and 5 'is directed upwards.

For example, the tubes 3 and 4, as well as the rods 5, 5 'and 9 are made of steel and their assembly is carried out by welding.

Advantageously, the tubes 3 and 4 and the rods 5, 5 'and 9 have a circular section.

The set of cells 2 is produced, for example by press, in a mesh of steel wire so as to comprise a plurality of longitudinal cells 11, parallel and of substantially semi-cylindrical shape connected by parallel edges 12. The locations of the edges 12 correspond to those of the rods 5. The mesh can be made of 0.5 mm wire.

diameter with 4 to 8 meshes per linear centimeter.

Thus, it is possible to manufacture separately, on the one hand the frame 1 by welding, on the other hand by the assembly 2 by stamping.
Then, the assembly 2 is placed on the frame 1 so that the rods 5 are housed in the hollow of the edges 12, the convexity of the cells 11 being directed towards the side of the rods 9. The folded lateral edges 13 of assembly 2 are introduced into the spaces 8 and welded at 14 under the corresponding extreme rod 5. In addition, weld points 15 can be provided from place to place along the edges 12, between the assembly 2 and the rods 5.

Substrate 1-2 is then degreased, then painted with a clear epoxy paint. Finally, after the paint has dried, a layer of silicone is applied at least in the concavity of the cells 11.

This provides a large, inexpensive dough support with rigid cells.
