A handle is provided on the door body 12. A sealing strip 114 is provided around the open side of the box body 11.

[0047] Instructions for use:

[0048] When using this embodiment, a trolley with a bottom plate height consistent with the bottom plate height of the box body 11 is also required for use, so as to facilitate the baking tray mounting device 2 to be easily put into the box body 11 or taken out of the box body 11. Specifically, the following steps are involved:

[0049] (1) First, open the door 12, push the trolley to the open side of the box 11 and align it with the box 11, then pull the baking tray mounting device 2 to move the baking tray mounting device 2 onto the trolley, thereby taking the baking tray mounting device 2 out of the box 11;

[0050] (2) The baking tray 4 with the milk foam is sequentially placed on the baking tray rack 23, and then the baking tray mounting device 2 is moved to the open side of the box 11 by a trolley and aligned with the box 11, and the baking tray mounting device 2 is moved into the box 11 by pushing the baking tray mounting device 2, thereby achieving the baking tray mounting device 2 being put into the box 11;

[0051] (3) Close the door 12, rotate the screw 193 so that the screw 193 is located in the opening of the limit plate 196, and then rotate the force rod 192 to drive the threaded sleeve 191 to rotate, thereby locking the door 12 and the box body 11;

[0052] (4) The controller 35 controls the heating tube 13 to start heating, and turns on the vacuum pump 14 to extract the steam generated by heating in the box body 11, thereby reducing the humidity in the box body 11, which can prevent wrinkles on the surface of the milk foam caused by high humidity. Since the box body 11 is exhausted from the exhaust port at the top of the box body 11 during the steam extraction process, the steam at the upper part of the box body 11 is more than that at the lower part of the box body 11. In order to speed up the drying speed of the milk foam at the upper part of the box body 11 and reduce the influence of the upper steam on the appearance of the milk foam, in this embodiment, the upper part and the lower part of the box body 11 can be dried. The lower heating tubes 13 are controlled separately. Specifically, in actual application, 11 rows of heating tubes 13 are arranged in the box body 11. Upper temperature sensors 31 are arranged on the side walls of the box body 11 corresponding to the upper 5 rows, and lower temperature sensors 32 are arranged on the side walls of the box body 11 corresponding to the lower 6 rows. The upper 5 rows of heating tubes 13 are controlled by the temperature data detected by the upper temperature sensor 31, and the lower 6 rows of heating tubes 13 are controlled by the temperature data detected by the lower temperature sensor 32. At the same time, the heating time of the heating tubes 13 can be controlled by the timer 33.

[0053] (6) After heating is completed, drying is completed. Since the box 11 is in a negative pressure state, it is necessary to open the air supply valve 36 to inflate the box 11, and detect the real-time pressure in the box 11 through the pressure sensor 34. When the pressure becomes normal pressure, the door 12 can be opened by reversely twisting the force rod 192; the baking tray mounting device 2 is taken out of the box 11 by a trolley and moved to the cooling area in the workshop to cool the dried milk foam.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
