Apparatus for taking material to be treated into and out of high pressure tank

摘要

An apparatus for taking a material to be treated into and out of a treating high pressure tank such as a heating sterilization tank comprises a conveyor passage interconnecting the high pressure tank and a water tank and constituted by two or more partially cylindrical casings connected in a side-by-side relation and each rotatably accomodating a rotary closure member having 2 to 6 blades adapted to make a sliding contact with the inner peripheral surface of the casing. Due to a specific phase difference between the blades of adjacent rotary closure members, the conveyor passage is always closed by some of the blades. A pair of endless conveyor chains, carrying a plurality of treating vessels accomodating the material, are adapted to run along both side surfaces of the conveyor passage through the high pressure tank and the water tank in a timed relation to the rotation of the rotary closure members. Means are provided for returning the leaked liquid back to the high pressure tank from the water tank.
