Abstract

Multilevel cooking / regeneration method and system for cooking / regenerating ovens to serve in a single run comprising a primary multilevel cooking / regeneration function, where, through the selection of a button of the primary cooking / regeneration function Multilevel is accessed by a secondary function that, in the configuration phase of a first level corresponding to the tray with the preselected food, activates a control mechanism which considers some times configured later, managing them so that it allows, in successive guided phases, to load the trays corresponding to the levels, then remove from the oven all the food at the same time.

Description

Multilevel cooking / regeneration method and system for cooking / regenerating ovens to serve in a single run.

The present invention aims at a multilevel cooking method / regeneration system, applicable to ovens for cooking / regenerating food for the community, such as restoration ovens, to serve in a single run. Conventionally, in the literature, the term “cooking / regeneration” means a food preparation which provides that the food is prepared on the day; The system, usually the most requested and widespread, requires a kitchen in the stall and the consumption of food in the same place where it has been cooked in a time immediately following production. The term "regeneration" means either a phase of elaboration of the so-called system with cooling link-as a phase of the system with -freezing link-. The first involves a manufacturing technique with which the food, prepared hot, after cooking / regeneration, is subjected to rapid cooling, passing in a very short time from + 60 / 70ºC to + 10 / 2º in the heart of the treated product , then once stored for a few days, be reactivated or regenerated at the time of eating the food through appropriate ovens with a temperature of + 120ºC for 30 minutes or more. In the second case, on the other hand, the products are pre-cooked hot, enclosed in mono-containers or multiportions, immediately after undergoing a cooling process at -30ºC and stored at -18ºC until the moment of regeneration with commonly convection ovens.

Scope

Multilevel cooking / regeneration is a particular option that allows you to manage the cooking / regeneration time or temperature in the heart of the food of each individual tray, placed at different levels from each other, on the oven rack. Notoriously, a furnace for collective restoration, such as those for gas, convection, mixed or electric, includes a spacious cooking / regeneration chamber, inside which, through an access door, the trays are placed one above the another, where each tray placed on a different level from the other with respect to the bottom of the cooking / regeneration chamber, is suitable for containing the food to be cooked or regenerated. Such cooking / regeneration will be subordinated and linked to the con fi guration of the type of cooking / regeneration, which should be homogeneous for the food inserted in the different levels. In this case, it is planned to use at least one probe with several needles for each tray in such a way that the sensor serves to detect the temperature in the heart of the food to be cooked / regenerated.

In the state of the art, ovens for cooking / regeneration are conventionally known which provide for predefined programs or operating types already installed by the manufacturer. For example, in WO-A-2005/066547 (Rational) it is stated that the corresponding parameters are also pre-installed inside such programs or operating types. These types of operation or pre-installed cooking / regeneration programs normally have cooking / regeneration parameters that are installed in the possible installation field, usually in the middle. These types of operations or pre-installed cooking / regeneration programs allow the user to use an apparatus in an easy and efficient way since such devices represent a huge work speed and offer time savings.

A drawback is the fact that in known cooking / regeneration appliances, the pre-installations are very global and normally standardized. WO-A-2005/066547 (Rational) proposes a cooking / regeneration apparatus that aims to overcome the disadvantages of the prior art and in particular has high fl exibility and possibilities of use with, at the same time, easy service delivery .

WO-A-2005/066547 (Rational) describes a cooking / regeneration apparatus in which at least one parameter is pre-installed for at least one predefined program, such as in the form of a cooking / regeneration program and / or cleaning program, and / or for at least one predefined type of operation, as in the form of a type of cooking / regeneration or cleaning operation. The predefined parameter is modifiable by at least one button for the variation of an element of use of the cooking / regeneration apparatus and the variation during a certain time can be con fi rmed, accepted and / or automatically memorized by the cooking / regeneration apparatus with at less a confirmation button for con fi rmation and / or memory of the operating button of the device itself after such determined time. With this it can be foreseen that the determined time can be set, preferably with the operation button, and in particular it ranges from approx. 1 to 30 seconds after the last con fi rmation of the operation button. It is preferable that the con fi rmation and / or memory operation button comprises at least one indicator that at the time of the con fi rmation and / or of the memorization of at least one parameter emits a signaling sound and / or at least in such scope makes change the color of an operating button, in particular on the display, preferably the digital button. In addition, it must be understood with the concept “Confirmation” an acceptance of parameters modified exclusively for the program to be followed at that time or for the type of operation in progress, while the concept “memorization” includes an acceptance of the parameters modified in a memory that bases the corresponding parameters for all the programs or types of operation to be carried out in the future. Finally, the device comprises at least one display and / or at least one touch screen.

EP1653833 (Jurgens) proposes a cooking device for the regeneration of appropriate products to be cooked in a regeneration chamber, in which at least two regeneration planes, in particular each secured in an introduction module, are or can be placed at various levels, each regeneration plane having a clock associated with a warning device after the predetermined regeneration period has expired, and where there is a control operator element, provided with a data input unit, to manually initialize the clock of each regeneration plane loaded with the food to be cooked, and equipped with a display unit to inform about the period of time which is a characteristic of initialization of the clock.

It happens frequently, that, in the field of restoration, a series of dishes that have different cooking / regeneration times, must be served in a single run, so that each dish can be ready for consumption and at temperature. At the moment the applicant is not reasonably notorious of any previous document that illustrates a solution to achieve the aforementioned objective.

This and other objectives are achieved with the present innovation according to the characteristics of the appended claims by means of a multilevel cooking / regeneration method and system for cooking / regenerating ovens to serve in a single run comprising a primary multilevel cooking / regeneration function. , where, through the selection of a button of the multi-level primary cooking / regeneration function, a secondary function is accessed which, in the phase of setting up a first level corresponding to the tray with the pre-selected food, activates a control mechanism. which considers successively set times, managing them in a way that allows, in successive guided phases, to load the trays that correspond to the levels, and then take out all the food at the same time.

These and other advantages will be deduced from the following detailed description of a preferred embodiment solution with the help of the attached schematic drawings whose execution details should not be construed as limiting but only illustrative.

Practical realization of the invention

The primary multi-level cooking / regeneration function is accessed through a series of menus, on a display 10, which is guided from the oven's ignition to the "multi-level" function. (Figure 1).

On the left screen, indicated with A, the levels present in the oven are numerically related, for example level 1, level 2, level n, in this case up to ten, plus a complementary line for access to the cooking configuration / regeneration. The selection of the individual level to which the corresponding tray with the food to be cooked / regenerated corresponds occurs by sliding the cursor through the command 100 and then giving the "enter" con fi rmation by pressing the command 100. Alternatively, by pressing directly on the display, in correspondence with the preselected level, in touch screen mode.

Operationally, therefore, the successive screen is displayed.Byse proceed by setting the parameters of a cooking / regeneration type: cooking / regeneration mode, choice between convection 20, steam 21 or combined 22, then temperature 30, the indicated humidity percentage 40 as a self-cleaning function, fan speed 50 and other possible functional complements, such as maintenance after cooking / regeneration and alternating ventilation. Therefore, returning to screen A, the times or temperatures at the heart of the different levels are set or the modality is used to serve in a single roll defined in this case as "just in time".

The sequence of these operations can be reversed: first the configuration of “times / temperatures in the heart / service just in time” and then that of the cooking / regeneration / regeneration parameters. At this point, maneuvering on the “start” button 60 will turn on cooking / regeneration / regeneration.

It will also be possible to set a possible preheating cycle, which on the display 10 will appear as “loading” in correspondence with the programmed levels level 1, level 2, level n, and, at the closing of the door after loading, the cooking / regeneration / regeneration. The different timers associated with the levels will begin to count backwards while the temperatures in the heart will vary as a result of cooking / regeneration.

When a time expires or when a temperature is reached in the heart, the graph of the corresponding level level 1, level 2, level n, will flash and the alarm will sound. The levels will also be configurable “on the fly”, that is, during operation. In this case, the operator will introduce a new tray and, always acting on the configuration of levels level 1, level 2, level n, will assign a time or a temperature in the heart. At the time of con fi rmation with the "enter" 100 control button the timer will start counting or the temperature in the heart will be controlled. Pressing the “start / stop” button 60 will obtain the temporary stop of the cooking / regeneration, that is to say, both the timer and the controls will stop, pressing the button 60 again will start again. To definitively stop cooking / regeneration, press the “start / stop” button 60 for a long time. The modalities and the number of levels corresponding to level 1, level 2, level n, to which it is possible to assign the temperature control in the heart will depend on the type of probe used: a level for the multipoint probe or as many levels as they are the multipoint probe points for the separate needle probe (per individual control point). For example: a level with the 4-point or 4-level multipoint probe with the individual point probe and separate needles. The probe connector in the heart will always be the same.

It is also possible to assign a name to the corresponding level level 1, level 2, level n, for example "POTATOES":

•

the level number and the assigned name “3-POTATOES” will appear on the display,

•

“Save with name” the program initially set,

•

set a delayed start-up of cooking / regeneration by means of the dedicated “date / time” button.

A possible variant of the management system could be to preconfigure the cooking / regeneration and time data depending on well-known applications, such as the "regeneration" of dishes on the plate or on the tray. At this point the operator must only start the oven in p mode. ex. “MULTI-LEVEL REGENERATION”, enter the trays or plates, press the button relative to the level occupied, you will be presented with a predefined time that you only have to confirm with the “enter” button 100. All this without continuity solution, going to occupy the levels that are released, until the time of the last planned level is finished or the “stop” button is pressed. However, the possibility of varying the preconfigured parameters will remain.

It may happen that a series of dishes have to be served, with different cooking / regeneration times, in a single run, so that everything is presented at the correct temperature. With “Multilevel” management in “Service just in time” mode this will be possible. The way to set the type of cooking / regeneration (mode / temperature / humidity / fan speed / possible complements) will be the same, while the activation of the mode -in a single run- or “service just in time” in phase If the first level is set (independent of position), it starts a particular control method and system, which will take into account the times set forth below, the display 10 will exclusively propose that modality and manage it in a way that allows, loading the levels 1, level 2, level n, in opportune and successive guiding phases, the extraction of the furnace at the same time. For example (see Figure 2), setting level 5 to 45 ', level 7 to 30' and level 3 to 15 ', at the time of the start you will be asked to load level 5, while on display 10 levels 3 n 7 will indicate “WAIT”. After 15 ’, when 30’ are left to finish, the indication “LOAD” will appear in the display at level 7 instead of “WAIT”. After another 15 ’, when 15’ are left by the end, the indication “LOAD” instead of “WAIT” will appear on the display at level 3.

At this point the timers will be aligned and will reach the end of cooking / regeneration at the same time, allowing an optimized room service - in a single run. It will not be possible (con fi guration lock) to use the “service just in time” mode when other levels have been previously programmed for “time” or “heart probe”. In “start”, during the load waiting phase, the free levels in the “time” mode will, however, be used in a subordinate manner, in that it is limited as a maximum time, to the time remaining at that time. In practice, it will not be possible (con fi guration lock) to allocate a time greater than that displayed at that time. Also in the "service just in time" mode it will be possible to assign a name to the levels and save the program.

2. Statement motivated according to articles 29.6 and 29.7 of the Regulations for the execution of Law 11/1986, of March 20, on Patents on novelty and inventive activity; quotes and explanations in support of this statement The invention, according to claim 1 of the application, relates to a multi-level oven for cooking / regenerating food to serve in a single run. The oven is equipped with a control system that manages the treatment times of the food at different levels so that the user is guided in the process of successive loading of the trays in each of them in order that all cooking / regeneration processes end simultaneously. Document D01 discloses a control system that processes the cooking times of food in a set of microwave ovens associated with each other such that, once the cooking times associated with each of the ovens have been introduced by the user, the The system calculates, from the longest cooking time, the instants in which each of the remaining ovens must begin to work so that all the food is ready to serve at the same time. In the case of document D01, the loading of the ovens is carried out at the beginning of the process and the ovens are automatically and successively put into operation, at the precise moment at which cooking must begin in each of them. The procedure described in the application under study, in which the oven emits a signal to indicate to the user what level to charge at that time, is considered an unfavorable way of operating, being preferable to carry out the loading of all levels at the initial moment (see documents D01 and D03). This avoids unnecessary oven openings and saves the work of introducing the trays in successive loads. It is considered that a person skilled in the art wishing to serve different foods with different cooking / regeneration times in a single run could, without making use of inventive activity, incorporate the control system described in D01 into a multi-level cooking / regeneration oven such as the one disclosed in document D02, instead of a microwave set. As regards the dependent claims 2 to 6 of the application, the design characteristics related to the exchange of information with the user, in particular the data entry screens and the display of information on the status of each level (load / wait), they are part of the usual practice known to a person skilled in the art, no element of inventive significance being appreciated in them. For the reasons set forth herein, it is concluded that the combination of documents D01 and D02 would eliminate the inventive activity of claims 1 to 6 of the application (art. 8.1 Law 11/1986 of Patents).
