An apparatus for transporting and at the same time cooling sensitive and perishable goods such as sliced vegetables by means of an auger including a transport screw disposed in a trough-like housing provided with an insulating jacket and an insulated lid arranged in spaced relationship from the transport screw, wherein the transport screw has coils with bulged rounded outer edges which are spaced from the trough housing wall and wherein a coolant injection pipe is disposed in the space between the transport screw and the lid of the trough for introducing a cooling fluid into the trough while the goods are moved therethrough thereby providing direct contact of the cooling fluid with the large surface area of the goods to be cooled for efficient and rapid cooling of the goods.
