ABSTRACT OF THE DISCLOSURE Apparatus for conveying and handling delicate articles such as fish, in accordance with the present invention, includes an elongated inlet duct adapted to extend into an article storage region, such as the hold of a ship. The suction producing means provides for a flow of air through the elongated inlet duct at a velocity sufficient to entrain the articles in the air flow and to carry same through the inlet duct. A separating means is interposed between the suction producing means and the inlet duct for receiving articles passing through the inlet duct and for separating such articles from the air flow. The separating means includes a hollow chamber of generally circular cross- section defining a generally upright axis of symmetry, such chamber having an air inlet channel connected to the inlet duct and an air outlet channel connected to the suction producing means whereby the latter maintains a sub- atmospheric pressure in the chamber. In accordance with the invention both the inlet channel and the outlet channel are generally tangentially disposed with respect to the circumference of the chamber so that air entering the chamber via the inlet channel moves in a rotational pattern around the chamber axis and thence outwardly of the outlet channel without reversing its direction of rotation. Articles entrained in the entering flow axe guided around the chamber axis by the interior wall of the chamber and move downwardly within the chamber in a spiral path under the influence of gravitational forces thereon.
