Description

The utility model relates to the field of oven technology and can find application in the field of heat treatment of products, mainly in the confectionery and baking industries (cookies, gingerbread cookies, rolls, etc.).

There are a number of analogues of the claimed utility model from world-known information, among which the closest to the set of essential features is the “Conveyor Confectionery Furnace”, patent for invention of the Russian Federation No. 2133093. The decision was made as a prototype.

The furnace contains a bed, a tunnel baking chamber, and a system of electric heaters. Transportation of baked products inside the chamber is carried out on removable pallets along fixed guides using a chain conveyor with pushers. Electric heaters are located in two tiers and are divided into zones. The system of electric heaters has a tiered and zone adjustment of the power output with tracking a given process in automatic mode with feedback on the mass and type of baked product.

Known utility model has significant disadvantages:

- a large variation in the heating temperature of the dough pieces when moving along the tunnel chamber affects the quality of the baked product;

- due to the significant mass of the baking chamber, due to the large thickness of its walls, up to 65 percent of production time is spent on preparatory operations related to cooling and heating the baking chamber, which significantly reduces the productivity of baking;

- uneven heating of the monolithic tunnel baking chamber often leads to unacceptable deformations of the furnace design.

The purpose of the utility model is to eliminate the disadvantages inherent in the prototype.

The technical result of the utility model is to improve the quality of the baked product; increased baking performance; reduction of the risks of deformation of the furnace structure.

The specified technical result is achieved due to the fact that the conveyor oven containing a bed, a baking chamber, a system of electric heaters, a conveyor installed inside the baking chamber and made with the possibility of moving the baked goods on removable pallets along fixed guides using a chain conveyor with pushers, characterized in that the baking chamber is made in the form of identical thin-walled muffle modules, combined into a single structure and separated from each other by heat-compensation connecting elements, and in each muffle module, devices are installed for heat treatment and moving dough pieces, and the covers and bottoms of the muffle modules form an airtight baking chamber with controlled stable temperature conditions.

Devices for heat treatment of dough pieces are made on the basis of electric heaters (heating elements) or gas burners.

Devices for moving dough pieces are made using supports and sliding guides of the hearths.

Utility Model Implementation

The baking chamber is made in the form of identical thin-walled muffle modules (1), combined into a single structure using special heat-compensating connecting elements.

In compact muffle modules (1), all the necessary units and devices for heat treatment and movement of dough pieces, including electric heaters (electric heaters) or gas burners, supports and hearth sliding guides, are mounted.

The conveyor movement is carried out using the drive mechanism (2). The furnace is controlled by the remote control (10) and the control cabinet (4). At each end of the modular furnace, tables are installed: a drive table (5) and a tension table (6), on which the corresponding sheets (7, 8) are mounted. To protect the operator from the heat of the furnace, a visor (9) can be installed.

On the side of the tension table (6), a spring tension mechanism (11) and a tension mechanism (12) are installed.

Each muffle module consists of a frame (3), has a cover (13), a bottom (14), conveyor guides (15), lower (16) and upper (17) roads, a pipe (18) for supplying hot air to the muffle.

Covers (13) and bottoms (14) of the muffle modules form a sealed baking chamber with a controlled and stable temperature regime, which ensures high quality of baked products.

The thin-walled steel construction of the muffle modules significantly reduces the mass of the baking chamber and significantly increases the productivity of baking due to a corresponding reduction in the time of preparatory operations. Heat-compensating connecting elements (not shown in the drawings) can be made in various ways and their design does not affect the technical result achieved. For example, they can be made of ceramic. Heat-compensating connecting elements provide a certain necessary gap between the heating elements of the design of the baking chamber, which eliminates temperature stresses and, as a result, unacceptable deformations. Thus, the essence of the proposed utility model lies in the modular construction of the baking chamber, where each module has a stable and controlled temperature regime and in the use of heat-compensating connecting elements, which eliminates all the disadvantages of the prototype.
