In an apparatus for the cooling of softly packaged food-stuffs, such as pouches with foods, said pouches are immersed inside a tank (52) into a cooling liquid with a density that is lower than that of the pouches. A floor is arranged inside the tank above the tank bottom so as to support the pouches, which floor comprises a grid (14). At least one jet (15) is arranged between the tank floor and the grid, said jet being adapted to eject liquid in a generally upward direction, and said jet during the ejection being moved so as to vary the flow pattern inside the tank. The motion of the jet provides an exceptionally good cooling effect, which is believed to be attributable to a combination of advantageous circumstances, viz. that no pouch is constantly stationary and that the pouches do not cover the surfaces of other pouches. The motion of the jets can be provided by a mechanically relatively simple arrangement, in which the jets are mounted on arms (16), which arms are rotated around a vertical axis (17).
Apparatus for treatment of softly packaged food-stuff objects by immersion of said objects into a body of liquid, said apparatus comprising a vessel, said vessel comprising an essentially horizontal bottom wall and at least one essentially vertical side wall, said bottom wall and said at least one side wall being essentially fluid-tight and being joined in an essentially fluid-tight fashion in order that said vessel is adapted to hold a body of liquid, a floor for supporting said objects within said body of liquid at a level above said bottom wall, said floor comprising a grid or a grate with openings, jet means arranged below said bottom wall and above said floor, said jet means being adapted to eject liquid from a level within said body of liquid and in a generally upward direction so as to agitate said body of liquid, and means to move said jet means while ejecting liquid in a generally oscillating or revolving pattern.
