Saccharomyces cerevisiae activity on-line detection equipment

The utility model relates to the technical field of yeast detection, in particular to saccharomyces cerevisiae activity online detection equipment which comprises a water tank with a thermometer, a slot is formed in the outer wall of the water tank, an annular clamping groove is formed in the annular edge of the water tank, an adjusting mechanism is arranged above the water tank, and the adjusting mechanism comprises a circular ring and a centrifugal tube. The bottom face of the circular ring is fixedly connected with a clamping ring, the clamping ring is movably connected with the annular clamping groove in a clamped mode, the bottom face of the circular ring is movably attached to the upper edge of the water tank, and the side face of the circular ring is fixedly connected with an arc-shaped piece and two holding rods. The centrifugal tube slides downwards to be immersed in water at the temperature of 20 DEG C in the water tank, then the holding rod drives the circular ring to rotate and shake, so that the
