Device and method for compacting a flowable solid material

摘要

The invention relates to a device for compacting a flowable solid material, comprising a compacting space (1) provided with a supply opening (3) for supplying material to be compacted to the compacting space and a discharge opening (5) for discharging compacted material from the compacting space (1), closure means for effecting a gastight seal of the compacting space and pressure means for creating a reduced pressure inside the compacting space in the hermetically sealed condition of the compacting space. The pressure means comprise volume means for changing the volume of the compacting space, and/or the compacting space comprises a first part for accommodating the material and a second part that can be sealed gastight from the first part by further closure means, in which said second part the pressure can be reduced by the pressure means in the situation in which the second part is sealed gastight from the first part by the closure means. The invention furthermore provides a method to be used with such a device. <IMAGE>
