Method and apparatus for compacting flowable solids

Abstract

The invention relates to a method and an apparatus for compacting flowable solids, in particular powders, flours or similar materials, preferably by packing in packagings or sacks. In order to increase the process reliability, there is provision for evacuation of the solid and its sack packaging to take place in a likewise evacuated environment.

1 . Method for compacting flowable solids by evacuating the solids and bagging and/or packaging the solids in an evacuated container, characterized in that the evacuation of the solids and their bagging are performed in similarly evacuated environment. 
   
   
       2 . Method in accordance with  claim 1 , characterized in that the evacuation of the solids and their bagging is performed in separate chambers that are connected air-tight to one another. 
   
   
       3 . Apparatus for compacting flowable solids by evacuating the solids and bagging and/or packaging the solids in an evacuated container, characterized in that the apparatus has a storage chamber ( 1 ) for the solids and a downstream sack chamber ( 2 ) for the bagging, and both chambers ( 1 ,  2 ) can be evacuated and connected air-tight relative to one another. 
   
   
       4 . Apparatus in accordance with  claim 3 , characterized in that a tightly sealing shutoff device is arranged between both chambers ( 1 ,  2 ).
