The utility model relates to a seafood
fermentation thermotank with an air interchanger in the technical field of
seafood processing, which comprises a
fermentation thermotank, a sealing cover is arranged at the upper end of the
fermentation thermotank, a circular groove is arranged at the lower end of the sealing cover, a sealing ring is slidably connected in the circular groove, and a pair of L-shaped plates is fixedly connected to the outer end of the sealing cover. A limiting rod is arranged on the inner wall of the L-shaped plate; when exhausting is carried out, the
processing motor and the electric push rod are started at the same time, then the vertical
pipe rotates and moves upwards, then the ventilation
pipe rotates and moves upwards in the fermentation constant-temperature box, exhausting is carried out at different positions in the fermentation constant-temperature box, finally, gas is exhausted from the inlet and outlet, and when
oxygen is inflated into the fermentation constant-temperature box, the
processing motor and the electric push rod are started at the same time. The steps are repeated,
oxygen is filled into the fermentation constant-temperature box from the inlet and the outlet, a plurality of ventilation pipes are not needed during ventilation of the constant-temperature box, the production cost is further reduced, and the fermentation constant-temperature box is practical.
