The utility model discloses a
food grade liquid
cold storage tank, which relates to the technical field of
food storage and specifically comprises a support and a Miller plate
evaporator, a
cold storage tank body is arranged at the top of the support, and a
breather valve, a stirring structure, an inlet hole and a liquid inlet are arranged at the top of an inner cavity of the
cold storage tank body. The inner cavity of the
refrigeration tank body is provided with a pressurized automatic rotary cleaning CIP spray head, the stirring structure comprises a stirring rod movably connected with the top of the inner cavity of the
refrigeration tank body, the top end of the stirring rod is provided with a stirring blade I, and the bottom end of the stirring rod is provided with a stirring blade II. According to the food-grade liquid
refrigeration tank, manufacturing of the Miller plate
evaporator and connection of the refrigeration plate and the
liquid layer are achieved through the
laser welding technology, the deformation probability of the inner wall of the refrigeration tank body is reduced, the smoothness and the use strength of the interior of the refrigeration tank body are guaranteed, and when the refrigeration tank is used, the refrigeration plate directly makes contact with liquid in the tank, so that the refrigeration effect is improved. The heat exchange efficiency is optimized, and the using effect is improved.
