The invention discloses automatic equipment for ocean bait microalgae preservation. The automatic equipment comprises a high-pressure air
bottle,
seawater treatment equipment, a microalgae
incubator, a lamp tube, flocculant automatic feeding equipment, a preservation
barrel, a preservation agent storage
barrel and a controller box, the
seawater treatment equipment is connected with a water inlet of the microalgae
incubator, a discharging port of the microalgae
incubator is connected with a first feeding port of the preservation
barrel, a discharging port of the flocculant automatic feeding equipment is connected with a second feeding port of the preservation barrel, a discharging port of the preservation agent storage barrel is connected with a third feeding port of the preservation barrel, a main delivery pipeline of the high-pressure air
bottle is divided into three branches, the first
branch extends into the microalgae incubator from a lower-portion air inlet, and the second
branch extends into the microalgae incubator from an upper-portion air inlet. The automatic equipment can automatically complete steps of culture, condensation, collection and preservation of ocean bait microalgae and is reasonable in structure, high in
automation level, simple to control, short in microalgae culture period, high in yield, high in risk resistance and low in cost.
