Dry liquids having a particle size distribution (cumulative undersize) are prepared by passing the liquids and a hydrophobic, pyrogenically prepared silica through a clearly defined, spatially limited shear zone in which the liquids are broken up into small droplets and are surrounded by the hydrophobic, pyrogenically prepared silica.

Dry liquids, and processes for their preparation

An apparatus for filling containers, said apparatus comprising a feed nozzle which may be placed over the feed orifice of the container, the feed nozzle being so constructed that the solids may be introduced under pressure and the container being surrounded by a cage, as well as a process for filling containers, in particular with finely divided solids having a high air content by

Apparatus and process for filling large containers of different sizes and shapes

An apparatus and method for dispensing fine particle material from a container such as a flexible intermediate bulk container. The invention includes a dispensing assembly that has a dispensing device that is secured to an outlet tube of the container. Securement is achieved by a strap member wrapped about the container's outlet tube and a clamping casing and/or by an inflatable member that expands outward from the clamping casing. The casing surrounds a transport tube which is axially shiftable following securement of the clamping casing to the outlet tube. A head piece with gas cavity and radial and oblique extending ports is provided at the end of the transport tube. The dispensing device is inserted into the outlet tube below a blocking member provided at the base of the outlet tube. Following attachment of the outlet tube to the clamping casing, the blocking member is released. The transport tube is then released from a first position, shifted and then fixed in a second position. The second position places the head of the dispensing device into the main compartment of the container and above the released blocking member. At this location gas, is injected through the ports and product is drawn out through the interior of the transport tube. In an alternate embodiment, there is used, either alone or in combination with the headpiece, an injection branch for directing a jet of air down the central axis of the transport tube. In another embodiment, a constricted member having a venturi configuration is provided in the same area within the transport tube as the outlet of the injection branch.
