Abstract: A tank (2) specially suited for transporting slurries, such as wine grapes (60), while reducing the tendency of the slurry to surge during transport. The tank includes an outer frame (6) and an inner container (4). The frame, typically made of steel, defines a central open region (5) within which the container is supported. The container is preferably plastic, or other thermal insulating material, to reduce heat transfer through the walls of the containers to the slurry. The circumferential sidewall (8) of the container has vertical corrugations (52) sized and spaced to inhibit surging of the slurry material within the tank during transport on a truck (47).
