A pressure vessel (1) for steam treatment of product to be peeled in a steam peeling system has substantially the shape of a sphere with opposed flattened side surfaces. The pressure vessel (1) is rotatable and has at least one internal lifting feature (51a, 51b, 51c) for entraining and raising product relative to the axis of rotation of the pressure vessel (1) during rotation of the pressure vessel (1). The pressure vessel (1) also at least one internal region (53) which is closed-off against ingress of steam during product treatment, said region (53) defining a steam saver. The pressure vessel (1) may be incorporated in a product treatment system also including a batcher for delivery of product to be peeled. The system may provide for accelerated pressure drop on completion of a peeling operation, as well as including arrangements to minimise release of entrained solid matter and/or odours in exhaust steam. A control system enables unproductive displacement of the pressure vessel to be minimised.
