Abstract

A bread oven (1) is heated by a burner (9) located above the oven. Air is blown (6) into the combustion chamber (8) then down ducts (not shown either side of the cooking shelves (2). Hot gas also passes through gaps (16) between each shelf, then returns to the heating zone or is vented (10).

FOUR DE BOULANGERIE COMPACTCOMPACT BAKERY OVEN

Il s'agit d'un four de boulangerie à soles fixes de type à recyclage c'est-à-dire dont la chauffe est assurée par la circulation des gaz de combustion  It is a baking oven with fixed floors of the recycling type, that is to say the heating is ensured by the circulation of combustion gases.

entre les chambres de cuisson.between the baking chambers.

Par rapport aux fours existants celui-ci est moins encombrant, plus économique à fabriquer et il peut être placé sur une étuve car le foyer, la turbine de ventilation et les générateurs de buée sont situés audessus des chambres  Compared to existing ovens this is less bulky, more economical to manufacture and it can be placed on an oven because the hearth, the ventilation turbine and the steam generators are located above the rooms

de cuisson.Cooking.

L'objet de la présente demande d'invention sera mieux comprise grâce  The object of the present invention will be better understood thanks to

aux dessins annexés. La figure 1 est une coupe verticale longitudinale du four.  to the accompanying drawings. Figure 1 is a longitudinal vertical section of the furnace.

Les figures 2, 3, 4 sont des coupes horizontales.  Figures 2, 3, 4 are horizontal sections.

Les pains à cuire sont placés dans les chambres de cuisson (1) sur les dalles réfractaires (2). Les repères (3) représentent les portes d'accès aux  The baking loaves are placed in the baking chambers (1) on the refractory tiles (2). The marks (3) represent the access doors to

chambres de cuisson et les repères (15) représentent l'isolation thermique.  baking chambers and the marks (15) represent the thermal insulation.

La façade avant comprend la hotte (4) et la table de travail (5).  The front panel includes the hood (4) and the work table (5).

La turbine (6) située en bout d'arbre (7) actionnée par un moteur électrique non représenté aspire les gaz de combustion en provenance du foyer ouvert (8). Le brûleur à mazout ou à gaz (9) est disposé verticalement au-dessus du foyer vertical (8). Les gaz de combustion sortant de la turbine sont chassés vers l'arrière du four. L'excès étant évacué par la cheminée (10), ils descendent par les deux colonnes arrières (13) puis circulent dans les espaces  The turbine (6) located at the end of the shaft (7) actuated by an electric motor (not shown) sucks the combustion gases from the open hearth (8). The oil or gas burner (9) is arranged vertically above the vertical hearth (8). The combustion gases leaving the turbine are expelled towards the rear of the furnace. The excess being evacuated by the chimney (10), they descend by the two rear columns (13) then circulate in the spaces

(16) entre les chambres de cuisson.(16) between the cooking chambers.

Les gaz de combustion balaient entièrement les espaces entre les chambres de cuisson grâce aux directrices (17) et chauffent ainsi régulièrement  The combustion gases completely sweep the spaces between the cooking chambers using the guidelines (17) and thus heat regularly

les voûtes et les soles des chambres se cuisson.  the vaults and the floors of the rooms are baking.

Ensuite, les gaz remontent par la colonne centrale arrière (12) en direction de la turbine (6). Au passage, ils se mélangent avec les nouveaux gaz chauds en provenance du foyer (8). Le foyer est ainsi refroidi par un double flux de gaz, flux d'arrière en avant en partie basse et flux d'avant en arrière en partie haute du foyer. Les gaz de combustion passent autour des générateurs de buée  Then, the gases rise through the rear central column (12) in the direction of the turbine (6). By the way, they mix with the new hot gases from the hearth (8). The hearth is thus cooled by a double gas flow, flow from back to front at the bottom and flow from front to back at the top of the hearth. The combustion gases pass around the steam generators

(11) constitués par des tubes disposés transversalement.  (11) constituted by tubes arranged transversely.

Le cycle de circulation des gaz recommence alors à nouveau.  The gas circulation cycle then begins again.
