ABSTRACT OF THE DISCLOSURE A freeze-thawing tank assembly includes an upright vessel having a hollow defined therein for accommodating therein a quantity of fluid medium to be treated, and closed at an upper end by a lid and at a lower end by a normally closed discharge valve, and a plurality of double-walled structures accommodated within the hollow of the vessel in equally spaced and parallel relation with each other. Each of the double-walled structures has a fluid passage defined therein for the flow of a heat-exchanging fluid medium and also has fluid inlet and outlet communicated with the fluid passage. The fluid medium to be treated may be alternately frozen and thawed by passing the heat-exchanging medium through the fluid passages in the double-walled structures.
