Referring to fig. 8-12, the principle of the present embodiment is:

in this embodiment, to further improve the utilization rate of the heat energy (i.e. hot steam), the adjacent tray devices are grouped to form an integrated mutual heating system, and the integrated mutual heating system is used to improve the utilization rate of the heat energy, which is specifically as follows:

referring to fig. 8 to 10, in the present embodiment, adjacent tray devices of the present embodiment may be disposed in a frame body to form an integrated mutual heating system, which is aimed at discharging hot steam in an air flow channel through an exhaust port, and the discharged gas may be blown to the adjacent tray device and used by another tray device, thereby improving utilization of heat energy, and furthermore, the present embodiment is further provided with a synchronizing ring, which may be driven to rotate clockwise and counterclockwise by a driving wheel, and the clockwise or counterclockwise rotation of the synchronizing ring may directly drive the outer tub to rotate clockwise or counterclockwise, and when a third gas source continuously supplies gas into the air flow channel through a drainage tube, and when the outer tub is driven to rotate by the rotation of the synchronizing ring, the position of a drainage tube on the outer tub may also be changed, so that, when the position of the drainage tube is changed, hot steam may be supplied into the air flow channel from different angles, and through direct guidance of the drainage wall (since the extending direction of the drainage wall is extended toward the inner tray body), hot steam may be supplied into the inner tray body from different angles, thereby improving efficiency and utilization of baked steamed bread resources;

it should be noted that:

first, the tray devices in the same integrated heat exchange system of this embodiment may further control the first rack to move through a driver (which may be an air cylinder, not shown in the drawings), and when the first rack moves, it may transmit the movement of the first rack to the gear and drive the gear to rotate, and further drive the second rack to move by the gear, and the substrate of each tray device is connected to the first rack and the second rack, respectively, so when the first rack and the second rack move, it may drive the tray devices to approach or separate from each other, in the energy saving mode, the tray devices may be controlled to approach each other, and the hot steam exhausted from the airflow channel of each tray device may blow to another tray device, and keep the temperature of the other tray device or be further utilized by the other tray device; in another mode (except the energy-saving mode, such as a normal mode), the driver controls the tray devices to be far away from each other, so that the situation that the steaming effect of the tray devices is influenced due to too close distance of the tray devices can be avoided; moreover, in the embodiment, one driver can be used for simultaneously controlling the two tray devices to move, so that the energy consumption can be further reduced, and the aim of saving energy is fulfilled;

secondly, this embodiment is in order to reach the exhaust steam of airflow channel and assemble, and the air current of assembling can flow farther distance, and "the impact effect" to the object is stronger, consequently, can further ensure the result of use of hot steam, more detailed said: hot steam in the air flow channel can enter the exhaust hood through the guide of the exhaust fan, and because the condensed fluid is arranged in the exhaust hood, the section diameter of the condensed fluid can be changed from the direction of the air flow to increase and then decrease, referring to fig. 11, the section diameter of the condensed fluid close to one side of the exhaust fan is gradually increased from the direction of the air flow, the other side is gradually decreased from the direction of the air flow, the former can guide the air flow to an air outlet formed between the exhaust hood and the condensed fluid to ensure the air outlet efficiency, and the latter can converge the air flow to the axial direction of the condensed fluid, so that the convergence purpose is achieved (the caliber of the air outlet end of the exhaust hood can also be gradually decreased to assist the convergence of the air flow);

thirdly, when the outer tub rotates clockwise or counterclockwise alternately, the present embodiment can cooperate with the exhaust to supply air to the adjacent tray device, that is: when the outer barrel rotates clockwise or anticlockwise, the position of the exhaust end of the outer barrel changes, so that the contact area of the gas exhausted from the gas flow channel and the adjacent tray device can be increased, and the utilization rate of the hot steam is further increased.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the scope of the present invention, which is intended to cover any modifications, equivalents, improvements, etc. within the spirit and scope of the present invention.
