An installation for carrying out a continuous multi-stage industrial process includes a housing that defines a first space and a second space that is connected to the first through a first connecting channel. Different pressure conditions prevail in these spaces during the course of the process. A process material is passed sequentially through the first space, the first connecting channel and the second space. A transported material is provided in the first connecting channel to form a free-flowing sealing zone with the process material and ensures that different process conditions will be maintained in the two spaces, and in particular that different pressures will be maintained in the two spaces. The invention also relates to a multi-stage continuous industrial process using such an installation.

A method for the manufacture of foamed plaster utilizing a mixture of powdered casting plaster, powdered limestone and hemp fibre. The mixture is fed into a Venturi apparatus (40) under the influence of gravity. Compressed air may be supplied to the Venturi apparatus (40) through an inlet pipe (41) causing air and solid particles to be sucked into the Venturi apparatus (40). The elongated tube is provided with an inlet nozzle arranged to receive a mixture of water mixed with detergent agents. Further, the tube (50) is provided with an inlet nozzle (56) arranged to receive compressed air such that the elongated tube (50) delivers the mixture to a mixing and spray head (60) so as to feed the resulting mixture to a moulding means.

A processing vessel (1) provided with a material inlet (2, 3, 4, 5) and a processed material outlet (25) wherein the material flows continuously through the vessel which is split into a series of zones (6, 7, 8) through which the material passes wherein the zones are shielded from each other by controlling the rate at which the material flows and an increasing level of vacuum is applied inconsecutive zones and the system is provided with acoustic energy which imparts energy to the process material by virtue of the contact between the zone dividers and the process material and processing material in such a vessel.

A capsule for mixing substances includes a chamber having first and second ends. A piston is fitted in the chamber. The piston has a proximal end facing the first end, and a distal end facing the second end. A mixer element is arranged within the chamber between the piston and the second end. The mixer element is disposed at a distal end of a mixer rod. The piston has an aperture through which the mixer rod passes. The piston and mixer element are separately displaceable relative to the first and second ends and relative to each other. The piston includes a plurality of cavities within the piston, such that one cavity is separated from another cavity and filled with a different ingredient substance.

A device for wetting particles, in particular wood particles, with an application agent, at least one conduit transporting a fluid as a fluid stream and an end section which forms an outlet. The fluid can be introduced in the direction of the main flow into a container containing the particles, via the outlet. The particles are in the container in a loosened state and/or can be loosened. The application agent, for spraying by a nozzle device with a speed component directed against the main flow direction, can be introduced into the fluid stream and can be guided to the particles by the fluid stream.
