ABSTRACT OF THE DISCLOSURE The invention relates to a discharging apparatus which includes a pressure vessel, a collecting vessel beneath the pres- sure vessel, and a discharge vessel beneath the collecting ves- sel. The pressure vessels have overflow means for discharging material, in its hot liquid form, into the collecting vessel. Coolant means, such as water, are included in the collecting vessel to quench the material and form granulates of the material, and the level of the coolant means is kept constant by coolant supply and discharge means controlled by floats. A first valve is located at the bottom of the collecting vessel and the valve is opened when the level of the granulate reaches a predeter- mined height. The granulate is then discharged to the discharge vessel which is also filled with a coolant. A second valve is included at the bottom of the discharge vessel. The interior of the discharge vessel is kept at the same pressure as the interior of the collecting vessel until the second valve is to be opened, whereupon the pressure of the discharge vessel is exposed to the ambient. The material is withdrawn through the opened second valve.
