Abstract
Description
En boulangerie, les fours, utilises pour la cuisson du pain, utilisent comme énergie, soit l'électricité chauffant des résistances placées dans les chambres de cuisson, soit la combustion du mazout ou du gaz, nécessitant l'emploi d'un bruleur et d'un foyer central. In bakeries, ovens, used for baking bread, use as energy either electricity heating resistances placed in the baking chambers, or the combustion of fuel oil or gas, requiring the use of a burner and d 'a central foyer.
Les fours électriques ont des avantages par rapport aux fours chauffés au gaz ou au mazout, mais ils ont l'inconvénient d'une utilisation plus onéreuse, liée au court de l'électricité. Electric ovens have advantages compared to ovens heated with gas or oil, but they have the disadvantage of a more expensive use, related to the short of electricity.
Pour limiter cet inconvenient, l'EDF propose des tarifs moins elevés l'été que l'hiver et, toute l'année pendant les heures de nuit. To limit this drawback, the EDF offers lower prices in summer than in winter and all year long during night hours.
Malheureusement, malgré ces tarifs particuliers, la dépense annuelle d'électricité est encore sensiblement plus importante que l'utilisation du mazout ou du gaz . Unfortunately, despite these special rates, the annual expenditure of electricity is still significantly higher than the use of fuel oil or gas.
Pour diminuer-encore cet inconvénient, certains constructeurs ont imaginé des fours mixtes, comportant une partie chauffée par le gaz ou le mazout, et une autre partie chauffée électriquement. To further reduce this drawback, some manufacturers have imagined combi ovens, comprising a part heated by gas or fuel oil, and another part electrically heated.
Cette solution est imparfaite étant donné que, la partie chauffée a l'électricité ne peut jamais etre chauffée au gaz ou au mazout et inversement, la partie chauffée au gaz ou au mazou ne peut jamais être chauffée électriquement. This solution is imperfect since, the part heated with electricity can never be heated with gas or with oil and conversely, the part heated with gas or with oil can never be heated electrically.
Le perfectionnement, objet de la presente invention consiste a placer, a demeure, dans certains endroits des fours chauffés au gaz ou au mazout, des résistances etectriques d'une puissance suffisante pour chauffer l'ensemble du four. The improvement which is the subject of the present invention consists in permanently placing, in certain places in ovens heated with gas or oil, electric resistances of sufficient power to heat the whole of the oven.
Ce perfectionnement peut être appliqué â tous les modeles de fours : fours a étages ( recyclage ou a vapeur) et fours a chariots. This improvement can be applied to all models of ovens: deck ovens (recycling or steam) and rack ovens.
Dans les fours a étages, l'emplacement des résistances peut être choisi pour avoir un chauffage unique de l'ensemble du four, ou au contraire de façon a conserver certains avantages spécifiques des fours électriques (chauffage séparé de chambres de cuisson et réglage des températures de voute et de sole). In deck ovens, the location of the resistors can be chosen to have a single heating of the entire oven, or on the contrary so as to retain certain specific advantages of electric ovens (separate heating of baking chambers and temperature regulation vault and sole).
Independemment des avantages énumérés ci-dessus, le perfectionnement donne au boulanger la possibilité de changer immediatement d'énergie en cas de panne du système de chauffage en service. Independently of the advantages listed above, the improvement gives the baker the possibility of immediately changing energy in the event of a breakdown of the heating system in service.
La compréhension de l'invention faisant l'objet du présent document, sera facilitée par la description suivante, faite en se référant aux dessins annexés qui sont des coupes verticales des fours
La figure 1 représente un four à étages à recyclage (od la transmission de chaleur est faite par un courant d'air chaud entourant les chambres de cuisson).Understanding the invention which is the subject of this document will be facilitated by the following description, made with reference to the appended drawings which are vertical sections of the ovens
FIG. 1 represents a multi-stage recycling oven (where heat is transmitted by a current of hot air surrounding the cooking chambers).
Les résistances électriques 1 sont groupées et placées dans le courant d'air, en amont ou en aval du ventilateur 2. The electrical resistors 1 are grouped and placed in the air stream, upstream or downstream of the fan 2.
Le foyer 3 assurant avec un bruleur a gaz ou a mazout le chauffage du four dans les périodes ou l'électricité est chère (hiver et heures de jour). The hearth 3 ensuring with a gas or oil burner the heating of the oven in the periods when the electricity is expensive (winter and daytime hours).
Cette disposition correspond a un chauffage uniforme de l'ensemble du four. This arrangement corresponds to uniform heating of the entire oven.
La figure 2 représente un four semblable a celui de la figure i, mais où les résistances électriques sont placées a l'intérieur des chambres de cuisson, ce qui permet d'avoir une indépendance entre les différentes chambre de cuisson. FIG. 2 represents an oven similar to that of FIG. I, but where the electrical resistances are placed inside the cooking chambers, which makes it possible to have independence between the different cooking chambers.
La figure 3 représente un four a étages, a vapeur transmission de chaleur pour des tuyaux de vapeur 4. FIG. 3 represents a stage oven, with heat transmission steam for steam pipes 4.
Les Les résistances 5 sont disposées autour du foyer 6 (chauffe au mazout ou au gaz) et assurent le chauffage global du four. The resistors 5 are arranged around the hearth 6 (oil or gas heating) and provide overall heating of the oven.
La figure 4 représente un four a étages avec résistances l'intérieur des soles de cuisson appliquée a un four a vapeur
(solution semblable a celle décrite pour la figure 2.FIG. 4 represents a tiered oven with resistances inside the cooking floors applied to a steam oven
(solution similar to that described for figure 2.
La figure 5 représente un four'a chariot, composé d'une enceinte 7 dans laquelle circule le courant d'air chaud, qui traverse le chariot 8 sur les étages duquel sont disposés les pains a cuire. FIG. 5 represents a carriage oven, composed of an enclosure 7 in which the current of hot air circulates, which crosses the carriage 8 on the floors of which the buns are baked.
La circulation d'air est assurée par le ventilateur (9) et son chauffage, par un échangeur de température (10) comportant le brûleur à gaz ou à mazout. Air circulation is ensured by the fan (9) and its heating, by a temperature exchanger (10) comprising the gas or oil burner.
Comme dans le four de la figure 1, les résistances sont placées en amont ou en aval du ventilateur. As in the oven in Figure 1, the resistors are placed upstream or downstream of the fan.
I1 est possible de changer d'énergie de façon instantanée par la simple manoeuvre d'un inverseur électrique. It is possible to change energy instantly by the simple operation of an electric inverter.
