This invention relates to the field of cooking equipment technology, and more particularly to a spherical cooking equipment with distributed steam control. The technical solution includes a central interlayer fixedly installed on the outer wall of the spherical
cooker. An air inlet
branch pipe connects the air inlet end to the central interlayer. A first and second heat-expanding
pipe, connected to the central interlayer, are fixedly installed on the inner wall of the spherical
cooker. Both the first and second heat-expanding pipes adopt a conical vortex structure and are attached to the inner wall of the spherical
cooker. This invention increases the heating area of the material through the first and second heat-expanding pipes. Furthermore, the inclined arrangement of the first and second heat-expanding pipes generates an oblique force along the spherical surface on the material near the air inlet and outlet ends during rotation. This forcefully pushes the material in the low-speed zone towards the center and upper part of the spherical cooker, allowing material that was not originally turning to enter the high-speed turning zone, thus compensating for the deficiencies of insufficient linear velocity and weak turning near the rotating shaft.
