Edible fungus strain fermentation tank

A purification tank is arranged on one side of the fermentation tank, an inlet in the lower end of the purification tank is communicated with a steam generator, the upper end of the purification tank penetrates through the fermentation tank through a steam inner pipe and extends to the bottom of the purification tank, a rotating head is arranged at the bottom of the purification tank, and a plurality of air outlets are formed in the rotating head. The lower end of the rotating head is rotatably connected with the bottom of the purification tank, the steam inner pipe is communicated with the upper end of the rotating head, and steam in the steam inner pipe is discharged through the air outlet and drives the rotating head to rotate. The pressure of the steam pushes the rotating head to rotate, and the culture solution is stirred while being heated, so that the culture solution is in a flowing state all the time, the condition that the culture solution is easy to cake is prevented, and the temperature and the co
