Abstract (en)
[origin: EP0436140A1] The invention relates to a process and an apparatus for cooling a pulverulent material by means of a cooling liquid during filling of a container with this material. The powder drops from the filling socket (1) onto a baffle plate (2a, 2b) and forms a finely distributed deflected flow, over which the cooling liquid is sprayed from a distribution grid (4a, 4b) provided on its underside with outlet openings. The baffle plate can consist either of a straight plate (2a) or an obtuse cone (2b). The configuration of the distributor grid for the cooling liquid is modified in accordance with the shape of the baffle plate. Liquid nitrogen is suitable as cooling liquid for many purposes. <IMAGE>
