Definitions

• the present invention concerns a device for preparing food.
• the invention has been made with particular reference to the field of preparations that require the transformation of food, modifying the properties thereof like for example colour, consistency, flavour.
• the most common transformation techniques include cooking. This is a family that covers a wide range of practices, offering a huge array of possibilities to the chef, ranging from baking, to steaming, to griddling, etc .
• Another common technique for transforming food opposite to cooking is through refrigeration, like for example the process for obtaining ice creams.
• a general purpose of the present invention is therefore to meet such a requirement.
• Another preferable purpose of the present invention is to provide a device for preparing food that promotes the killing of microbes, the conservation of nutritional properties, the fixing of colours and organoleptic properties of food and the enhancement of colours and consistency of food.
• the present invention concerns a device for preparing food comprising at least one cooking device and at least one food cooling device (preferably at least until refrigeration) , capable of operating simultaneously and joined adjacent to one another to define a respective hot area and a respective cold area (preferably for refrigeration) in front of them (preferably above them) , the areas being freely communicating portions of a single space that allows the free passage of food from one area to the other.
• the areas are preferably intended to respectively contain food to be cooked and to be cooled.
• the main advantage of the present invention is that of quickly cooking and cooling food, thanks to the presence of the two functionalities in a single work space. This allows the chef to obtain hot-cold and cold- hot temperature passages in quick succession without intermediate passages, fixing the desired properties in the product and implementing a new method for preparing food.
• the rapid cooling of food allows a reduction of microbes and fixing of colours.
• a subsequent and immediate high-temperature thermal shock enhances the colour and the consistency of the food.
• the simultaneous presence of the two functions allows the dish to be finished with the preferred function in a practical and quick manner, conserving the properties of the product. This allows innovative preparations in a context of extremely high quality and refinement, like that required in cookery shows, and in the most exclusive restaurants and hotels.
• the device for preparing food comprises suction means positioned exclusively at the hot area.
• the suction means are arranged to suck from the hot area according to a horizontal suction direction.
• the suction means can be positioned very close to the cooking area, and in some preferred embodiments can wrap around it, and the heat is thus immediately sucked up stopping an undesired natural flow thereof towards the cold area.
• the suction means are absent in the joining area between the hot area and the cold area, to leave such an area free and facilitate the quick transferral of food from one area to the other.
• the cooking device is capable of generating a cooking temperature greater than or equal to 100°C and the cooling device is capable of generating a freezing temperature less than or equal to 0°C.
• the cooking device has a cooking surface by contact with the food capable of reaching a temperature greater than or equal to 100°C and the cooling device has a freezing surface by contact with the food capable of reaching a temperature less than or equal to 0°C.
• said single space is delimited by a tank structure where the cooking and cooling devices are arranged on the bottom and where the top is open to allow access by an operator .
• the device for preparing food comprises a plurality of suction mouths arranged on vertical sides of the tank structure at the hot area.
• the cooking device comprises a cooking plate
• the cooling device comprises a freezing plate, adjacent to one another to lie on a single plane or on parallel planes.
• the heating plate and the freezing plate are preferably separated by a channel for collecting the food residue coming from the two plates.
• the channel communicates with a residue collection drawer.
• the cooking device and the cooling device are joined with the interposition of at least one layer of heat insulating material.
• the device for preparing food comprises, in addition to the cooking and cooling devices, a heatable closed space for food and a coolable closed space for food. They advantageously allow parts of preparations or preparations that are already complete to be conserved.
• the device for preparing food comprises a main body that supports the cooking device and the cooling device, so as to form a unit that is practical and quick to use.
• the invention concerns a process for preparing food characterised in that it comprises a first food cooling step where the food is cooled by placing it in contact with an area at a temperature less than or equal to 0°C, (so that the food can be at least partially frozen by this step) , a second step after the first where the cooled (or at least partially frozen) food is subjected to a thermal shock that quickly raises the temperature thereof (for example to a cooking temperature) by placing it in contact with an area at a temperature greater than or equal to 100°C, a third step where the food is cooked or cooled at the desired temperature.
• the second step is preferably immediately after the first step, where the term "immediately" means no longer than the time necessary to move the food by hand from the cold area to the hot area of a device according to the present invention.
• FIG. 1 schematically shows a perspective view of a preferred embodiment of a device for preparing food according to the present invention.
• figure 2 schematically shows a section according to the vertical plane II of figure 1.
• FIG 1 a device for preparing food according to the present invention is shown wholly indicated with reference numeral 1.
• the device 1 is in the form of a unit having at least two functions inseparable from one another and able to be carried out simultaneously, that of cooking and that of cooling food, where these two processes are able to be carried out on a single work plane 5.
• the work plane 5 comprises a cooking plate 10 and a cooling plate 15.
• the cooling plate 15 is capable of cooling food rested on it, preferably freezing it by taking it to a temperature less than or equal to 0°C.
• the cooling plate 15 is capable of reaching an adjustable surface temperature of at least - 38 °C, although there is no intent to set limits.
• the term "freezing" for the purposes of the present invention means any temperature less than or equal to 0°C.
• the two plates 10 and 15 are adjacent and extend horizontally so as to have a single access and work space 20 above them.
• the work space 20 in particular is preferably at least partially delimited by a tank structure 25, clearly visible in figure 2, on the bottom 26 of which the plates 10 and 15 are arranged, and open at the end 27 opposite the bottom to allow access by the operator from above.
• the area of the work space above the cooking plate 10 is intended to be a hot work area 30, whereas the area above the cooling plate 15 is intended to be a cold work area 35.
• the device 1 comprises a suction system 40 with suction means 45 associated exclusively with the hot area.
• suction means 45 are arranged horizontally outside of the hot area 30.
• the suction means comprise a plurality of suction mouths 45 (where the invention also considers the presence of only one mouth) . They are preferably arranged on at least one vertical or substantially vertical perimeter wall 50 of the tank structure that delimits the work area in the horizontal direction. Even more preferably the mouths 45 horizontally surround the entire perimeter of the hot area 30 with the exception of the side on which it is adjacent to the cold area.
• the mouths 45 are preferably oriented to suck air from the hot area 30 in the horizontal direction.
• suction means are not provided at the cold area 35.
• the two plates 10 and 15 are separated by a channel for collecting the food residue 55, the bottom of which is vertically lower than the two plates 10, 15.
• the channel carries the residue to a collection drawer 60, for example extractable for more practical elimination.
• the device 1 comprises a main body 65 that supports the two plates 10 and 15 in raised position with respect to the ground.
