Description

The utility model relates to devices for baking bread of periodic action in stationary and field conditions.

Known baking oven PHP-0.4 (Quick reference to the discipline "Technical means of the food service") [1], intended for baking bread, consisting of a frame, a baking chamber with a door, a furnace with an ash pan, a proofing chamber with a door, a chimney with baffle, nozzle, temperature controller and a set of baking molds. It has significant disadvantages: uneven distribution of heat in the processing chamber, which entails partial burning of bread; manual control of the parameters of the environment of the baking chamber; lack of an alarm notification of the end of baking time.

The technical task of the utility model is to ensure uniform temperature distribution inside the process chamber.

The technical task is carried out due to the fact that the device for creating a uniform temperature in the baking oven contains a chimney, a duct, a technological chamber, a grate, characterized in that for uniform distribution of heat around the entire perimeter of the technological chamber, a gas distribution grid and a sensor are rigidly fixed temperature connected through a wire to a control unit that controls the operation of the nozzle and fan fixed inside the process chamber.

The figure shows a device for creating uniform temperature in a baking oven, where indicated by pos. 1 - control unit; pos. 2 - nozzle; pos. 3 - grate, pos. 4 - wire; pos. 5 - firebox; pos.6 - insulation; pos. 7 - fan; pos.8 - gas distribution grill; Pos. 9 - process chamber; pos. 10 - channel gas duct, pos. 11 - temperature sensor; pos. 12 - chimney; pos. 13 - sampler; pos. 14 - oxygen analyzer; pos. 15 is a carbon dioxide gas analyzer.

A device for creating a uniform temperature in a baking oven consists of a control unit (1), rigidly fixed on the outside of the housing of the baking oven. The control unit (1) through a wire (4) is connected to a temperature sensor (11), it also contains an oxygen gas analyzer (14) and a carbon dioxide gas analyzer (15), a fan (7), an atomizer (2). Temperature sensor (11) (as an option, three are rigidly fixed at the inlet and outlet of the duct gas duct (10) and in the process chamber (9)). The sampler (13) is rigidly fixed inside the chimney, analyzes the flue gas content and is connected to an oxygen gas analyzer (14) and a carbon dioxide gas analyzer (15). An oxygen gas analyzer (14) and a carbon dioxide gas analyzer (15) are connected through a wire (16) to a control unit (1). The fan (7) (as an option, two) is rigidly fixed in the wall of the case so that the working part is placed inside the process chamber (9) on both sides.

A device for creating a uniform temperature in a baking oven operates as follows.

Hot air is supplied to the furnace (5). The temperature sensor (11) analyzes the temperature at the beginning and end of the duct gas duct (10), as well as in the process chamber (9), sends a signal to the control unit (1). The control unit (1) determines the temperature difference of the coolant at the inlet end of the channel gas duct (10), as well as in the process chamber (9). The exhaust flue gases pass through the chimney (12), the sampler (13) of the exhaust flue gases for oxygen analyzers (14) and carbon dioxide (15). Signals about the content of oxygen and carbon dioxide in flue gases are also fed to the control unit (1). The control unit (1) compares the sum of the signals with the program and transmits a command to adjust the air and fuel supply to the nozzle (2) in the furnace (5), due to which the optimum temperature in the process chamber (9) is maintained.

Due to this, a more intense heat exchange occurs between the heat carrier of the channel gas duct (10) and the heat carrier of the process chamber (9), which, in turn, allows the fastest and most uniform heating of products.

A device for creating a uniform temperature in a baking oven with forced movement of the coolant allows the fastest and most uniform heating of the dough pieces. An experiment in September 2017 showed the effectiveness of the application of technical development, which allows to reduce the time of heat treatment of bakery products by 10%, and the specific heat consumption by 22%.

Thus, the proposed device for creating a uniform temperature in the baking oven has a novelty and significant differences from the prototype, provides new useful characteristics, allows for uniform temperature distribution inside the process chamber. It can be used on a baking oven ПХП - 0.4 and is aimed at increasing the efficiency of its work.
