The invention discloses a downward pressing type stirring paddle and a stirring device, the stirring paddle comprises a stirring shaft, n blades are arranged along the peripheral wall of the stirring shaft at intervals, a downward pressing included angle ai is formed between the contour surface of each blade and the plane where the axis of the stirring shaft is located, and i = 1-n, ault; 90; and a plurality of through holes are distributed on the contour surface of the paddle. According to the present invention, the flowing dead zone can be effectively eliminated, the uniformity of the temperature field is improved, the cell inactivation caused by local overheating is prevented, the heat utilization efficiency and the cell activity of the fermentation tank are comprehensively improved, the stirring efficiency is improved, the reaction time can be shortened, and the yield and the quality of the finished product are improved. The method can be used for a biological fermentation process. 本发明公开了一种下压式搅拌桨及搅拌装置，所述搅
