Novel double-end drainage device of yeast dryer

The utility model relates to the technical field of drying equipment, in particular to a novel double-end drainage device of a yeast drying machine, which can enable the temperatures at the two ends of a cylinder body to be more uniform, improve the material drying effect, enable drainage to be smoother and reduce the use limitation. Comprising a cylinder body, two flow guide pipes, two water inlet pipes, two steam inlet pipes, two communicating pipes, two steam communicating pipes and two water drainage pipes, a drying inner container is arranged in the cylinder body, a cavity is formed between the drying inner container and the cylinder body, two connecting sleeves are screwed with two fixing sleeves respectively, and sealing tables are arranged on the two steam inlet pipes. A plurality of fixing pieces are arranged on the circumferential outer walls of the two communicating pipes at equal intervals, the two communicating pipes are fixedly installed in the two steam inlet pipes through the fixing pieces res
