Description

The present invention relates generally to apparatus for

  baking both sides of food products and more specifically a relatively compact cooking device for use with an existing grill and to allow efficient cooking of both sides of food products such as pieces of food.

minced meat.

  The attraction of food products such as minced meat and the like is greatly enhanced when the products are served as soon as possible after their preparation. Many commercial establishments therefore carefully control the time between the preparation of food products and their service to the customer so that the attraction of products

  satisfactory and that consumers are satisfied

  facts. At peak times, in a restaurant, it is usually possible to ensure a relatively continuous flow of cooked food products so that customers can be served quickly and efficiently, food being served very soon after preparation. However, at relatively off-peak hours, for example between usual meal times, it is not generally possible to ensure such a steady flow of food products when

  must be served at the right time after preparation.

  As a result, it is often necessary that the preparation

  After the customer's order is received, only products of the highest quality are served. This preparation is also generally necessary when a customer gives a "special" order that is not usual. Although customers are assured of receiving food products of the desired high quality and taste appeal,

  customers may not be satisfied with the extra time

  to wait for individual preparation

  food products as a result of such an order.

  It is thus desirable to have an apparatus for significantly reducing the cooking time of food products such as pieces of minced meat, so that the preparation of a customer order can be achieved quickly and efficiently during periods in which a continuous flow of cooked products is not assured. Customer satisfaction is. significantly increased as only freshly prepared products are served, the customer's order being satisfied

  in a relatively short time compared to the time required

  in the preparation of food products by

  classic one-sided grill.

  The cooking device according to the present invention is in the form of an accessory to be added to an existing grill so that it allows the cooking of pieces of ground meat and similar food products in a relatively limited amount. The device is suitable

  particularly well with a grill of industrial size

  it can be advantageously placed so that it is ready to be used, on the grill or near it but outside the zone of occupation when the grill is used in a normal way for cooking. only one face. When the cooking time has to be reduced for relatively small quantities of pieces of minced meat, the pieces can be placed on the grill and the cooking device according to the invention can advantageously be placed on them so that it ensures cooking very effective parts on their second side. The cooking device according to the invention is a relatively compact set, which can be handled with one hand and selectively placed on the associated grill. The assembly comprises a housing connected to a cooking electric heating plate which delimits an extended cooking surface, preferably of generally rectangular shape. In the preferred embodiment, the

  device according to the invention comprises a set of

  which is placed at a distance from the cooking assembly (for example on a hood or the like placed above the grill), with a heat-resistant flexible electric cable, connecting the control assembly to the cooking tray so as to that it is heated in a regulated manner. The control unit is thus advantageously placed at a distance from the heat of the grill, the flexible cable allowing the selective arrangement of

  the whole cooking on the grill at the desired location.

  When chopped meat and other food items are to be baked on both sides, the cooking set is placed over the pieces after they have been placed on the grill. In this respect, it can be seen that foodstuffs

  such as pieces of minced meat

  rance when there is a predetermined space between the cooking surface and the heating plate and the associated grill. For this purpose, the cooking assembly includes a spacing device associated with the cooking tray and intended to maintain the desired predetermined distance.

  between the cooking surface of the tray and the grill.

  In the illustrated embodiments of the present invention, the spacing arrangement of the cooking surface of the tray with respect to the grill

  has two support rails placed on the first sides. op-

  placed on the cooking surface of the tray. With this arrangement, the second opposite sides of the cooking surface are "free" so that the meat juice is not trapped, because, in this case, the pieces of meat

  chopped could be on the contrary "boiled".

  In a represented embodiment of the invention,

  Each of the support rails is generally L-shaped and has a spacing portion adjacent to the cooking surface so that the rail forms a spacing device of the assembly. Each support rail further comprises a

  part of support placed at a distance from the part of space

  respective location and which is preferably connected to the

  spacing portion by a curved corner portion.

  Thanks to this arrangement, the cooking assembly can be easily handled between a first low or active cooking position in which its cooking surface is substantially parallel to the grill and allows a cooking of two faces, and a second vertical position in which assembly is supported by the support portions of the two rails. In this second rest position, the cooking surface of the tray is distant from the grill and has a substantially vertical orientation. The preferred curved configuration of the corners of the support rails allows easy handling of the assembly between its first and second positions by tilting or pivoting the assembly around the portions forming the curved corners, without lifting the assembly at a distance of the surface of the grill. This preferred embodiment allows a convenient "rolling" of the cooking assembly between its use and rest positions, and further allows the cooking assembly to remain on the grill when not in use. for cooking both sides. Other features of the cooking device according to the invention facilitate its efficient and convenient use. In a preferred embodiment, a device with a low coefficient of friction is associated with the cooking surface of the tray so that it is in contact with the

  pieces of minced meat or other food products.

  Although such a device with a low coefficient of friction may consist of a suitable composition with a low coefficient of friction applied and directly bonded to the cooking surface, the embodiments shown use a heat transmission sheet having a low coefficient of friction, juxtaposed to the cooking surface of the tray and intended to be in contact with pieces of minced meat. The cooking assembly preferably includes an arrangement of fixing rails and clips on the opposite second sides of the cooking surface so that the low friction sheet can be mounted

  removable near the cooking surface of the tray.

  Although a shown embodiment of the invention includes support rails having a shape

  general L-shaped, designed to maintain the predetermined spacing

  Another embodiment of the invention includes different configurations of the support rails, arranged in such a way that they allow the low-friction sheet to be removably mounted in addition to the clamps and fixing rails. Two resilient clips are provided for temporarily associating the two support rails of this additional embodiment with the cooking tray, the marginal portions of the low friction sheet being held captive between the cooking tray and the support rails. . The low friction sheet is thus removably retained in position on the first opposite sides and on the opposite second sides of the extended cooking surface, which is thus advantageously insulated from the meat juice and alcohol

on the grill.

  Other features and advantages of the invention

  tion will become more apparent from the following description,

  with reference to the accompanying drawings in which: Figure 1 is a perspective showing the device for cooking the two faces in the working position on an associated grill, according to the invention; Figure 2 is a perspective of a cooking assembly of the cooking device according to the invention, in the inactive position or rest on the associated grill; Figure 3 is a section of the cooking assembly of Figure 2 along the line 3-3 of Figure 1; FIG. 4 represents a variant of the device

  according to the invention, allowing a selective adjustment

  FIG. 7 is a section of the variant of the

  appears from Figure 6; and Figure 8 is an enlarged supplementary section

  and partial of the cooking assembly of Figures 6 and 7.

  FIG. 1 represents a device 10 allowing

  both cooking food on both sides, according to the invention. The cooking device 10 is shown in association with a grill 12 having a flat horizontal cooking surface and a hood 14 placed above the grill 12. A grill and a hood are conventional in the apparatus

  restaurant, preparing food products

  such as pieces of minced meat, generally designated P in the drawings, the cooking device according to the invention being particularly intended

  to be used with an industrial size grill.

  In a preferred embodiment, the cooking device according to the invention comprises a cooking assembly 16 that can be placed on the grill 12, a control assembly 18 placed at a distance from the cooking assembly, for example on the hood 14, and a flexible heat-resistant cable that connects the cooking and control assemblies. The heat-resistant cable may be a shielded or metal-clad electrical cable

  which not only protects the electrical wiring inside

  against the heat of the grill 12 but which also resists deterioration due to inadvertent contact

  with metal spoons or the like commonly used

  on a grill. This advantageous feature of the heat resistant cable in the device

  cooking according to the invention allows the arrangement of the

  seems 16 cooking on the grill 12 at a time when

  when it is at rest, although the

  assembly of the remote control unit 18 of the grill 12 is ensured so that the control members are not

  not affected by the heat of the grill.

  Referring specifically to Figures 2 and 3 which. represent the preferred configuration of the cooking assembly 16. This assembly has a substantially box-shaped metal housing 22 having substantially vertical sides which define an open bottom (with the orientation shown in FIG. 3), a cooking plate 24 made of cast aluminum being connected to the housing 22 in which it is positioned. An electric heating element 26 is placed in the molded tray and is intended to ensure its heating, the tray defining an extended and flat cooking surface 28, preferably substantially rectangular (Figure 2) to be placed above

  pieces P on the grill so that they

they are cooking on both sides.

  The cooking plate 24 preferably comprises a fixed sensor. This sensor 30 and the heating element 26 are connected to the control assembly 18 by the flexible cable 20. The control assembly preferably comprises a thermostatic control and a control device. suitable timing for regulating electrical energy

  transmitted to the heating element 26.

  The cooking assembly 16 preferably has a suitable insulation placed between the cooking plate and the housing so that the heating of the housing 22 is

  minimized during operation of the tray 24.

  As clearly indicated in FIG. 3, such an insulation may advantageously comprise an insulation sheet 32 placed between the sides of the plate 24 and the sides of the casing 22, and a fibrous insulation 34 placed on the

  tray 24 inside the housing 22.

  The extended cooking surface 28 of the tray 24 of

  baking preferably has a suitable material

  the low coefficient of friction associated with it so that the cleaning of the cooking unit 16 is facilitated and the pieces P and the meat juices do not stick to the cooking surface. material with a low coefficient of friction (for example containing polytetrafluoroethylene) can be applied and adhered directly to the cooking surface 28, it is preferable for the cooking assembly 16 to comprise a low-friction "anti-adhesion" removable sheet 38

  friction, for example containing polytetrafluoride

  ethylene, juxtaposed to the cooking surface 28. A suitable polytetrafluoroethylene sheet is available from Chemical Pabrics Corporation, North Bennington,

  Vermont. It should be noted that the sheet 36 with low coefficients

  friction is not shown in Figure 2,

  and the cooking surface 28 of the tray 24 is thus visible.

  Since it is usually necessary to periodically replace the low coefficient sheet

  friction, the assembly 16 preferably comprises an arrangement

  temporary assembly of the sheet 36 against the cooking face of the plate 24. More specifically, two rails 38 for fixing are associated with the housing 22, on opposite sides, and two clamps 40 for fixing are intended to cooperate with the rails 38 The sheet 36 is thus mounted by arranging the sheet near the surface 28 of the plate 24, the opposite ends of

  the sheet being arranged around the fastening rails 38.

  The clamps 40 are then mounted on the rails 38 so that the sheet 36 is placed between each clamp and the corresponding rail. The "dovetail" configuration of the rails and clamps provides a robust attachment of the sheet 36 near the surface 28

cooking tray 24.

  As noted earlier, cooking both

  faces of the pieces P is achieved by manipulation of the

  The cooking surface of the tray 24 is placed above the pieces, the sheet 36 having a low coefficient of friction being in contact with the upper face of the pieces. In this regard, tests have shown that the attraction of chopped meat and similar foods is improved when a predetermined space is maintained between the cooking surface of the tray 24 and the grill 12. Thus, the assembly 16 baking includes two support rails 42 connected to the housing 22 on opposite first sides of the cooking surface of the tray 24 (the rails and clamps 38 and 40 thus being placed on the opposite second sides of the cooking surface). Each support rail 42 is preferably generally L-shaped, each having a spacer portion 44 positioned near the cooking surface of the tray 24, and a support portion 46 which

  preferably an acute angle with the part 44 of space

  cement. The two parts 44 and 46 of spacing and support of each rail 42 are preferably connected by

  a portion 48 forming a curved corner.

  As best shown in FIG. 3, the spacer portion 44 of each rail 42 maintains the desired predetermined spacing between the cooking tray 24 and the grill 12 during cooking of both sides of the pieces when the assembly 16 is placed. in its first lowered position. It should be noted that the arrangement of the spacing portions only on the opposite first sides of

  the cooking surface 28 gives the assembly 16 a configuration of

  such that the second opposite sides of the surface 28 are open or free during cooking of the two faces. The region below the cooking surface is not closed, such a closure can cause an "unwanted" boiling of the pieces P during the

baking both sides.

  The support rails 42 also provide support for the cooking assembly 16 in a second vertical position (FIG. 2) in which the surface

  the tray 24 has a generally vertical orientation

  and is placed at a distance from grill 12 when

  positive 16 is carried by the portions 46 of the support rails 42. The portions 48 forming curved corners on each rail 42 facilitate convenient handling of

  the set 16 between its first and second positions.

  More specifically, this advantageous configuration of the support rails allows the tilting or overturning of the cooking assembly 16 or its pivoting around the portions 48 forming the corners, without the cooking assembly having to be lifted from the grill, when is manipulated between his work and rest positions. A handle 50 connected to the housing 22 facilitates handling in this manner, the handle 50 being preferably placed above the casing 22 when the set 16 is in its low cooking position, the heating of the handle by the grill 12 being thus minimal. The support rails 42 allow the cooking assembly 16 to be held on the grill 12 even when it is in its vertical resting position, so that the spreading of the juices

  meat and the like at a distance from the grill is reduced to

  mum, and the heat losses of the cooking assembly are not excessive and allow a use

effective energy.

  The accelerated cooking of the two faces provided by the invention is particularly advantageous for reducing the cooking time of food products that can not be prepared quickly by cooking

  classic one-sided. For example, cooking classically

  Single-sided frozen meat pieces of 115 g beef are normally four and a half minutes. In the context of the efficient service provided by a restaurant, this time can be much too long when the order given by a customer has to be prepared. On the contrary, the device according to the invention allows baking of both sides of the frozen pieces of 115 g.

About 2 minutes.

  As the cooking of the two faces must be carried out in a relatively limited quantity, the embodiment

  of the invention described above has relative dimensions

  such that it allows the simultaneous cooking of two pieces of minced meat of 115 g. A 1500 W heating element 26 is used satisfactorily, the tray 24 being maintained at a temperature between about 190 and 230 C. In this present embodiment, the distance between the cooking surface of the tray 24 and the grill 12, determined by the spacing portions 44 of the rails 42, is preferably of the order of 10 to 12.5 mm, a dimension of 10.7 mm being very advantageous. This spacing is slightly less than the normal thickness of the commercially available 115 g minced meat pieces, so that the contact

  between the sheet 36 with a low coefficient of friction

  The whole of the cooking and the parts are ensured in an efficient way so that the meat presents a

good effect. of "cauterization".

  As the cooking of both sides progresses, the weight of the assembly 16 reduces the thickness of the pieces until the cooking surface of the assembly is maintained at the predetermined distance by the spacing portions 44. Preserving this predetermined spacing prevents unwanted compaction of the pieces of meat,

  may affect the attraction of the cooked product.

  The cooking assembly 16 preferably has a configuration such that it exerts sufficient pressure on the parts during the initial stages of the cooking of the two faces.

  for the parts to exhibit this desired effect of "cauterious

  For example, an embodiment of the present invention having a cooking assembly 16 for cooking two pieces of meat of 115 g preferably has a weight

  of the order of 4.5 to 5.5 kg. Naturally, it is desirable

  table that the cooking assembly 16 is not excessively heavy so that its convenient handling of a hand is not

not impossible.

  FIG. 4 shows a variation of the spacing portions of the support rails 42 of the assembly 16, these spacers bearing the reference 144 in FIG. 4. This configuration of the parts 144 allows a selective adjustment of the predetermined spacing of the cooking surface of the assembly 16 and the grill 12. More specifically, each spacer portion 144 forms two flanges 145 and 147. These flanges are intended to accommodate the lower bins of the housing 22 of the assembly 16 and to give two different spacings of the cooking surface

compared to grill 12.

  The left side of FIG. 4 shows the housing 22 placed on the edges 145 of the support portions 144 in such a way that the cooking surface of the assembly 16 is relatively close to the grill 12 (for example for cooking the two 45 g pieces of meat pieces). On the contrary, the right-hand part of FIG. 4 represents the arrangement of the stack 22 on the edges 147 of the parts 144, with a greater relative spacing between the surface

  cooking tray, in the stacker, and grill 12.

  The support rails 42 described above may have a configuration such that they comprise support portions 144 as shown in FIG. 4, with removable fasteners or the like which temporarily hold the support rails on the casing 22. rails 42 having the support portions 144 must be selectively positioned in a suitable manner with respect to the casing 22 so that the two flanges to be used 145 or 147 for the support

  of the housing 22 are placed opposite each other.

  FIG. 5 shows a variant for determining the predetermined predetermined spacing between the cooking surface of the tray, inside the casing 22, and the grill 12, the arrangement of FIG. 5 allowing a continuously varying selective adjustment. in a predetermined range. The arrangement shown in FIG. 5 may be used in place of the spacing portions 44 previously described for the support rails 42. The arrangement of FIG. 5 comprises a selectively adjustable spacing threaded member 244, preferably having a rounded head intended to be in contact with the grill 12. The threaded member 244 is held by a suitable locking nut 249 so that it can not move relative to a tapped block 251 in which

he passes.

  The predetermined predetermined spacing between the cooking surface of the tray inside the housing 22 and the associated grill is maintained during cooking of both faces by arranging an adjustable assembly of the type shown in Figure 5 at each of the four corners.

of the housing 22.

  Referring now to FIGS. 6 to 8 which show another embodiment of cooking assembly, previously designated by reference 16, according to the invention. In many respects, this additional embodiment is similar to the previous embodiment so that the elements corresponding to those of the first

  embodiment carry identical reference numerals

  ticks, preceded by the number 3. This embodiment

  addition of the cooking set, bearing the reference

  Article 316, is intended to include a removable

  "anti-adhesion" with a low coefficient of friction, juxtaposition

  placed on the cooking surface of the assembly, the cooking surface being isolated from the grill associated with the sheet

  with a low coefficient of friction.

  As indicated in FIGS. 6 and 7, the cooking assembly 316 is connected to associated members.

  such as 18 by a 320 resistance electric cable

  so much to the heat. The cooking assembly has a suitable metal case 322 associated with a casting plate 324 formed of cast aluminum, a suitable heat-resistant seal 325 being disposed between the housing and the cooking tray. An electric heating element 326 is placed in the heating plate so as to heat it, the plate delimiting a

  large and flat cooking surface 328, preferably having

  A generally rectangular shape (Figure 8), intended to be placed on top of pieces of meat P placed on the grill so that they are cooked on both sides. A solid temperature sensor 330 is disposed in the cooking plate, the sensor 330 and the heating element 326. being associated with the above-mentioned control unit 18 via the heat resistant flexible cable 320. A suitable fibrous insulation 334 is placed between the housing 322 and the tray 324 to minimize heating of the housing by the cooking tray, the gasket 325 opposing the penetration of meat juices and drugs into the insulation

  334 placed inside the case.

  As noted above, this embodiment of cooking assembly according to the invention comprises a low friction sheet, juxtaposed to the cooking surface 328 of the tray, so that the cooking surface is isolated from the associated grill. Thus, the sheet 336 with a low coefficient of friction comprises, in the arrangement shown, a device for removably mounting on the first opposite sides and the second

  opposite sides of the cooking surface 328.

  As in embodiment 16 previously described

  Finally, the cooking assembly 316 has two fixing rails 338 and fixing clamps 340 placed on the tray 324, generally on the second opposite sides of the cooking surface so that the corresponding marginal portions of the sheet 336 are fixed

  temporarily by juxtaposition to surface 328 of

  his. Unlike the embodiment described above

  The cooking assembly 316 has support rail variants 342 which are intended to allow temporary mounting of the sheet 336 on opposite first ends.

of the cooking surface 328.

  For this purpose, each of the support rails 342 has an elongated general configuration, each of them having

  a spacing portion 344 for maintaining the space

  predetermined cement desired between the cooking surface 328 and the associated grill during the cooking of the two faces of pieces P. The removable mounting of the sheet 336 with a low coefficient of friction is facilitated by the use of support rails 342 delimiting an elongated cavity 345, each cavity 345 having dimensions allowing the housing of a marginal portion or a respective edge of the cooking plate 324. A respective marginal portion of the sheet 336 is thus kept captive between the

  tray 324 and each rail 342 de.support (see Figure 8).

  The support rails 342, when they must allow a temporary mounting of the sheet 336 in this way,

  are temporarily fixed to the cooking tray 324.

  Two elastic fixing clips 347 are used

  for this purpose, each clamp 347 having a configuration perm

  placing its adjustment on a respective rail 347 'of mounting mounted on the plate 324 and on a respective rail 342 support. As shown, the surface of each support rail 342, facing outwardly, preferably defines a groove for cooperating with a respective resilient clamp 347 so that the support rails are firmly but temporarily connected to the cooking tray 324. It should be noted that, in the embodiment shown, each support rail 342

  has two grooves on its surface facing outwards, easily

  thus reading the interchangeability of the two support rails.

  As in the embodiment described above,

  According to the invention, the assembly 316 has a configuration allowing it to tilt or pivot between its low position of use and a substantially vertical position of rest. Each support rail 342 has a curved end 348 around which the assembly can tilt, a handle 350 being connected to the housing 322 so that it facilitates the tilting of the cooking assembly, this tilting being thus facilitated

Z575913

  without the cooking assembly having to be raised above the associated grill. In this embodiment, the support of the cooking assembly 316 in its substantially vertical position of rest is provided by two support pads 352 placed on the handle 350, these pads playing a role similar to that of the support portions 46 of the rails 42 mode

  embodiment described above.

  FIG. 6 generally shows the temporary assembly of the sheet 336 with a low coefficient of

  friction near the cooking surface of the tray 324.

  Opposite marginal portions of the sheet 336 are wrapped around the fastening rails 338, the clips 344 being attached to the rails so that the marginal portions of the sheet 336 are firmly retained. The sheet 336 is further mounted on the cooking tray 324 by winding the sheet upwardly around opposite edges of the tray 324, the support rails 342 then being placed on the cooking tray so that the sheet 336 is maintained. captive. Elastic clips 347 are then mounted on the respective support rails, the resulting configuration being such that the cooking surface of the tray 324 is isolated from the associated grill by the sheet 336. This arrangement may be desirable in order to minimize the contact of meat juices and the like with the cooking surface

of the heating plate.

  It is understood that the invention has been described and shown only as preferred examples and that we can bring any technical equivalence in its constituent elements without departing from its scope.
