A container with improved sealing, for improved security in the event of loading, transporting and/or unloading submicron particles, in particular nanopowder/nanoparticles, includes a connector for injecting liquid and/or gas. Such a container can also contain at least one inflatable seal (40) valve (3; 4). The container is provided with elements for changing the physical state of the material by heating, mixing or ultrasound bombardment. A method for using the container and an inflatable seal valve are also described.

A granular material stirring apparatus for breaking up clumps of a granular material in an interior of a storage bin comprises a base assembly for resting on a floor of the bin, an agitation rotor rotatably mounted on the base assembly, and a rotation device connected to the rotatable agitation rotor to cause the agitation rotor to rotate with respect to the base assembly. The agitation rotor may include a central member rotatable about a substantially horizontal axis and a plurality of stirrer members extending substantially radially outwardly from the central member to rotate about the substantially horizontal axis.

A tank, such as a fermentation tank, includes a scraper blade assembly slideably coupled to a bottom surface of the tank. The scraper blade assembly includes a blade arranged to displace solids deposited on the bottom surface of the tank out through an aperture arranged flush with the bottom surface of the tank.

A feeding device for an in-line screw machine with a shaft rotating in a feed container. A conveying screw is arranged in the direction toward the longitudinal axis of the rotating shaft. At least one disk wheel is allocated to each longitudinal side in the feed container. A separate drive is allocated to each disk wheel for purposes of rotational movement.

A bin sweep auger unplugging system for unplugging a central unloading sump in a storage bin. The bin sweep auger unplugging system generally includes an auger having a driven shaft with auger flighting, a drive unit having a drive shaft, and a clutch connected between the drive shaft and the driven shaft. The clutch selectively transfers the rotation of the drive shaft to the driven shaft of the auger. The drive shaft includes a clump breakup component that breaks up the clump of granular material above the unloading sump when the drive shaft is rotated. The clutch is disengaged when breaking up a clump of granular material to prevent the rotation of the auger.

A method and means for disaggregating aggregated particulate. A housing contains a rotational motor and a vibrating motor also has an auger drivingly linked to the rotational motor. Legs extend from the housing in the same direction as the auger and the device rests upon the aggregated particulate. Upon driving the rotational motor, the auger bores through the aggregated particulate, thereby disaggregating particulate. The vibrating motor is also driven to vibrate and further disaggregate the particulate. A plate device with a vibrating motor attached is also used to disaggregate the particulate, such as by teeth extending from the bottom of the plate that are driven into the aggregate by the weight of the plate when vibrated.

A powder recycling system includes a powder feeder, a remaining powder collector, a bridge breaker, a block powder filter, a cyclone separator, a particulate filter cleaner, an air pressure generation device and an electrostatic precipitator. The powder feeder provides a construction powder to a construction platform. The remaining powder collector for collects the remaining powder. The cyclone separator is used to separate the large-size powdery particles and the small-size powdery particles of the remaining powder from each other through a rotating gaseous stream. The large-size powdery particles fall down to the powder feeder due to gravity, and the small-size powdery particles of the remaining powder is removed from the rotating gaseous stream and transmitted to the particulate filter cleaner. After the small-size powdery particles of the remaining powder are filtered by the particulate filter cleaner, the suspended small-size powdery particles are transmitted to the electrostatic precipitator.
