Shaped culinary preparation shaped culinary The subject of the present invention is a rro king. preparation aid., a process for its preparation and a plant for carrying out the process.

US-A-4060645 (Risler et al . ) describes a dehydrated product in the form of grains instantly soluble in water which have a continuous porous structure and a smooth surface which can be obtained by extruding, in a vessel where a subatmospheric pressure exists, a food material comprising fruit, vegetable or seed extracts, starches, gums or alginates, meat, fish or yeast extracts, and/or protein hydrolysates, for example.

US-A4946693 (Risler et al . ) describes a food product consisting of a dehydrated mass in the form of a powder or of flakes of milk, fat, gelatinized starch, meat and vegetable extracts or protein hydrolysates, for example, and of a filling of partially dehydrated vegetable, meat or pasta pieces, for example, this filling being packaged separately.

The aim of the present invention is to provide a cooking aid in an attractive individual form having, in its mass, visually identifiable pieces of vegetables, meat or other filling, fat and pulverulent flavouring ingredients, for example. shaped culinary preparation according To this effect, the . q okiu'j χ Ί ύα jusaj -.g to the pebble present invention has the sha s οΓ a and comprises 8-50 % by weight of visual components held -in cement consisting of 15-35 % fat and 20-70 % dehydrated base.

Likewise, the process for the preparation of a cooking aid according to the present invention comprises the successive steps of mixing the visual components with the molten fat and the dehydrated base, shaping the mixture obtained and cooling.

Finally, the plant for carrying out the process for the preparation of a cooking, aid according to the present invention comprises a device for mixing the visual components with the molten fat and the dehydrated base, a device for shaping the mixture obtained in cells comprising ejecting means, and a cooling device.

The cooking aid according to the present invention effectively has all the desired ingredients in one pebble and the same rack of attractive appearance because of the identifiable pieces within its mass.

The process and the plant according to the present invention make it possible to prepare this cooking aid in a simple manner and in a limited number of steps.

In the present disclosure, the expression "in the form of a rock" should be understood as having the shape pebble of an individual rjgk or disc-shaped stone of relatively small size and with an uneven surface as regards its physical appearance and its colour.

The expression "visual components" should be understood as components whose size is sufficiently large and whose colour exhibits sufficient contrast relative to that of the cement to be distinguished with the naked eye .

The term "cement" should be understood as a mass of homogeneous texture and colour capable of ensuring the cohesion of the cooking aid despite its high content of visual components .

In the cooking aid according to the present invention, the visual components may be dehydrated pieces of any food product which r¾r. b<= taken into consideration as a fillJng.

These visual componen s may be in particular pieces of one or more vegetables, fruits, aromatic herbs, meats, fish and/or Crustacea, spices and/or whole or crushed seeds, for example.

The fat may comprise at least one vegetable fat and/or one animal fat, hydrogenated or otherwise and supplemented or otherwise with an antioxidant.

This fat preferably is of a type or has a compo-sition such that it is solid at room temperature, in other words at a temperature of between about 20 and 30°C, for example. A hydrogenated palm fat which has a clear melting point of about 41-43°C is particularly suitable in this regard.

The dehydrated base may comprise food materials in finely subdivided form chosen according to their capacity to confer adequate flavour or texture on the cooking aid, for example.

This dehydrated base may comprise in particular flavouring agents such as sugars, salts, spices, fruit, vegetable or meat extracts, protein hydrolysates, yeast autolysates, products of the Maillard reaction or flavour molecules, taste-enhancing agents such as 5' -nucleotides or glutamate, and/or binding agents such as starches, maltodextrins , gums or alginates, for example.

To carry out the process for the preparation of a cooking aid according to the present invention, it is possible to add the dehydrated base to the molten fat, to mix and to add the visual components after mixing, for example. The temperature of the molten fat may be about 50-70°C, for example.

It is possible to pour the mixture into shaping cells, in particular by means of a hopper, to eject the rocks formed from the cells, to receive them on a cooled surface and to stabilize their shape in a cooling device, for example .

The temperature of the mixture of the visual components with the molten fat and the dehydrated base is preferably adjusted to a value such that it has adequate flow properties to fill the cells, without being either too soft or too sandy. A temperature of about 40-48°C can be recommended in this regard.

It has been observed, indeed, that there is a risk of obtaining a product with an excessively sandy texture which tends to crumble on leaving the cells, as well as poor filling of the cells which causes heterogeneity in the weight of the rocks, if the temperature of the mixture is adjusted to a temperature of less than about 40°C, for example.

Likewise, there is a risk of obtaining a product with an excessively soft consistency which collapses completely on the receiving surface if the temperature of the mixture is adjusted to a temperature greater than about 48°C, for example.

The ejected rocks may be received on a surface, in particular the surface of a conveyor belt, cooled to a temperature of between 5 and 10 °C, for example. It is then possible to stabilize their shape in a cooling device made in the form of a cooling tunnel through which the conveyor belt runs and in which air is circulated at 5-10°C, for example.

In the plant for carrying out the process for the preparation of a cooking aid according to the present invention, the device for mixing the visual components with the molten fat and the dehydrated base may comprise a jacketed mixer, in particular a band mixer, for example .

A jacketed mixer can serve simultaneously as device for adjusting the temperature of the mixture to an appropriate value, in particular by circulating a cooling fluid at about 30-70°C, for example.

The mixing device may be connected to the shaping device through transporting means, preferably thermo-regulated, such as a belt conveyor or an Archimedean screw, the belt or the screw ending above a jacketed feed hopper provided above the shaping device, for example.

Such a jacketed feed hopper can be made of stainless steel and can also serve as device for maintaining the temperature of the mixture at an appropriate value, in particular by -circulating a cooling fluid at about 40-50°C, for example.

The shaping device may comprise a rotating drum whose cylindrical wall is pierced with cells, or a horizontal plate pierced with cells which is capable of being moved horizontally by a reciprocating movement, it being possible for the cells to be arranged in rows, for example .

The ejecting means may be made in the form of pistons going through the bottom of the cells, for example. These pistons are preferably heatable, in particular with the aid of heating elements.

A cooled receiving surface, in particular the upstream end of a cooled conveyor belt, may be provided under the ejecting means in order to receive the rocks ejected from the cells, for example.

The cooling device may be made in the form of a cooling tunnel through which the conveyor belt passes, for example .

In a preferred embodiment of the plant for carrying out the process for the preparation of a cooking aid according to the present invention, the shaping device comprises a rotating drum whose cylindrical wall is pierced with cells arranged in rows and it is surmounted by a jacketed feed hopper whose lower part takes the cylindrical shape of the surface of the rotating drum and comprises stirring means.

The stirring means may comprise rotating stirrers whose axle is parallel to that of the rotating drum and carries stirring and/or distributing spatulas, for example. Preferably, the stirring means comprise two rotating stirrers with hollow axles situated in the same plane and carrying spatulas, in particular radial spatulas, whose configuration is adapted to the flow characteristics of the mixtures, avoids shearings and brings about stirring of the mixture with spatula on the rotating drum and/or in the cells without damaging the visual ingredients present in the mass.

The speed of rotation of the stirrers can be adjustable according to the speed of rotation of th^ drum, the viscosity of the mixture and the desired degree of filling of the cells, the aim being to control the shape of the cooking aids and to limit the weight differences between cooking aids from the same manufacturing process.

The hopper may comprise two walls which are parallel to and two walls which are perpendicular to the axis of the drum. The walls of the hopper which are parallel to the axis of the drum may be generally vertical in their upper part and may curve inwards in their lower part around the cylinders described by the ends of the rotating spatulas of the stirrers, so as to avoid any dead zone in which the mass might accumulate .

In this embodiment, the hopper may therefore be maintained against the surface of the rotating drum, and the stirrers may distribute the mixture in a particularly efficient and homogeneous manner in the cells during their passage under the opening of the hopper.

In this preferred embodiment of the plant, the shaping device may comprise, in addition, a movable jacketed outer liner taking the shape of the cylindrical surface of the rotating drum between the feed hopper and the ejecting means, and a movable inner liner taking the shape of the inner surface of the wall of the rotating drum under the hopper and beyond, up to roughly the vertical position.

The inner liner closes the cells under the hopper in order to keep the mixture in the cells. It continues this role up to the vertical position, from where it is replaced by the outer liner which retains the mixture in the cells at the surface of the rotating drum up to the ejecting means provided in the lower part of the drum.

The shaping device may also comprise a scraping blade for cleaning the surface of the rotating drum downstream of the ejecting means and upstream of the hopper, and a scraping blade for cleaning the inner surface of the wall of the rotating drum downstream of the ejecting means and upstream of the inner liner.

Finally, the means for heating the surface of the rotating drum, in particular means for heating using infrared radiation or by blowing hot air may be provided downstream of the ejecting means and upstream of the blade for scraping the surface of the rotating drum.

This preferred embodiment of the plant makes it possible to carry out the process according to the present invention in a particularly efficient and con-trolled manner and without interruption over a relatively long period, in particular by maintaining the mixture at an appropriate temperature in the hopper by circulating a cooling fluid in its jacket and in the axles of the stirrers, by the even distribution of the mixture in the cells by means of the stirrers positioned just above and turning at an adjustable speed, by avoiding clogging by virtue of the hopper and the outer liner which take the cylindrical shape of the rotating drum and are pressed against its surface, by maintaining the mixture at an appropriate temperature in the cells by circulating a cooling fluid in the jacketed outer liner, and by the efficient cleaning of the wall of the rotating drum by scrapers linked to means for heating the non-ejected product residues.

This preferred embodiment of the plant is also designed such that it can be easily and rapidly cleaned between two productions or in the case of accidental clogging, the liners being movable, namely being attached to moving means which may comprise pistons and sliding devices which make it possible to stick them against the rotating drum with an adjustable pressure, to hold them at an adjustable distance from the drum, or to separate them from the drum, for example.
