Abstract: A powder sterilization method for sterilizing powder, in particular an active pharmaceutical ingredient in powder form or food in powder form, using fluid vapor, in particular steam. According to the invention, the fluid vapor is applied to the powder in an evacuated treatment chamber (3), in particular it is applied to the powder during its free fall along a drop section (7), in particular in countercurrent.

Abstract: The invention relates to a filling and/or emptying apparatus (1) and to methods for filling and/or emptying flexible containers (5), particularly sacks, with in particular hazardous, loose substances, preferably in powder form, comprising a filling and/or emptying neck (2) with an open end portion and at least one deformable disposable fastening ring (9), wherein the disposable fastening ring (9) is designed in relation to the internal diameter of the filling and/or emptying neck (2) such that once a container edge (7) is folded over around the fastening ring, preferably from radially inside to the outside, it is possible to insert, particularly to insert manually, the disposable fastening ring (9) in an end portion of the filling and/or emptying neck (2) so that the disposable fastening ring (9) is arranged substantially concentrically with the filling and/or emptying neck (2), and a radially outer fold-over portion (8) of the container edge (7) is arranged and/or clamped between an inner surface of the fill

Abstract: The invention relates to a discharging apparatus for discharging loose and in particular pulverulent material that is hazardous to health from rigid or flexible containers (12), in particular bags and barrels (13), comprising a discharge chamber (2) which has a discharge opening (5) for discharging the material after removal from a container (12) and which additionally has an insertion opening (3) for at least partial insertion of a container (12) into the discharge chamber (2). According to the invention, the discharge chamber (2) has a ventilation opening (4) which is arranged at a side of the discharge chamber (2) opposite the insertion opening (3) and which is connected to pump means (10) in such a way that an air stream can be generated inside the discharge chamber (2), which causes a laminar air flow starting from the insertion opening (3) and leading in the direction of the ventilation opening (4).

Abstract: This invention relates to a micronizing device for fluid jet mills which presents a containing body (2) internally delimiting a substantially cylindrical grinding chamber (3), a plurality of nozzles (18), each presenting a mouth (22) opening onto a radially internal side wall (8) of the grinding chamber (3), a supply duct (9) for material to be micronized, opening into the grinding chamber (3) and at least one injection duct (12) for pressurized fluid, in fluid communication with said nozzles (18). The nozzles (18) present a pressurized fluid injection direction (X-X) which is tangent to an imaginary circle included inside the grinding chamber (3). The radially internal side wall (8) presents, at each nozzle (18), a first portion (23) which is substantially perpendicular to the injection direction (X-X) of the respective nozzle (18).

Abstract: An apparatus for pumping free-flowing materials, having a receptacle coupled to a vacuum pipe and a pumping gas pipe, at least one filter, at least one supply pipe, and at least one drainage pipe for a material being associated with the receptacle. The apparatus includes a vertically extending cylindrical pump chamber configured to pneumatically pump liquids, powder, suspensions and pastes. Further, a device is mounted in an upper region of the pump chamber configured to separate liquid and powder. The device further includes a filter element and a float member. The float member is configured as a sealing element above, and a lower region of the pump chamber is coupled to the at least one supply pipe and the at least one drainage pipe for at least one of a liquid, a powder, a suspension, and a paste.
