摘要:
Method and device for freeze drying solutions and liquid containing solid substances, in which a vessel (1) is applied having a downwardly conical shape with inside a rotating mixing member (3) that moves with a small inter-space along the wall (2) of the vessel. With the new method in an advantageous manner free flowing products are obtained. Even new homogenous mixtures of a molecular scale of two or more substances are obtained, which are excellently usable in the industry of new materials.

A device for mixing of particulate material comprises a conical mixing vessel having a vertical axis, which vessel narrows in a downward direction and in which vessel at least one vertical mixing shaft is rotatable. A number of radial elements project from the mixing shaft, and carry paddles at their distal ends, adjacent the sidewall of the vessel. The radial elements are long and thin, while the mixing paddles are relatively short and are symmetrical round the axis of the elements. Due to the rotating paddles and the conical shape of the vessel, the contents move spirally upwardly. The layers of material closest to the wall end to have less spiral and more upwards movement, so that the intermediate layer is subjected to strong shearing forces that promotes mixing. A chopper is mounted in the top of the said vessel for chopping material in an upper portion of the vessel, above said mixing paddles.

摘要:
The invention relates a device for treatment, such as mixing, of particulate material (P), comprising a conical mixing vessel (1) having a vertical axis (2), which vessel narrows in a downward direction and in which vessel at least one vertical mixing shaft (3) is rotatable, from which mixing shaft (3) a number of radial elements (4) project that carry paddles at the outer end, that extend until the vicinity of the sidewall of the vessel (1). According to the invention there are a great number of long and thin elements (4), whereas the mixing paddles (5) are relatively short and are symmetrical round the axis of the elements (4) in which the mixing shaft (3) has a high to very high number of revolutions (N) such as for instance 100 through 1.000 revolutions per minute, so that the product (P) to be treated is very intensively mixed in a very short time.

Device for mixing powdery, granular and/or pasty material, comprising a conical mixing vessel (1) having a vertical axis (2) that narrows downwardly, and at least one mixing screw (13) that extends parallel to the innerside of the mixing vessel (1) and at the one hand makes a rotating movement around its sloping axis (14) and at the other hand makes integrally a revolving movement parallel to the innerside of the mixing vessel (1), in which the drive unit (6) for the mixing screw (13) is provided with a vertical passage (15). According to the invention the passage contains a rotating driveshaft (17) with at the lower end a horizontal, fast rotating rotor (18). The rotor (18) with its driveshaft (17) is mounted in a cage which is open at the lower end, of which cage (19) the upper end is hung on the lower side of the central shaft (17) of the drive (6) unit that extends into the mixing vessel (1). Preferably a separate driving motor for the rotor shaft (17) is mounted on the central drive unit.

The invention relates to a exchange system for filling machines which are provided with a system by which cylindrical carriers with an empty supply of zigzag folded tube foil can be replaced by a loaded carrier and that prevents that the filling unit during replacement is polluted or that any residue of the materials to be packed end up in the surroundings. These problems are prevented by making use of carriers with a loaded supply of tube foil that are mounted on the filling head. The exchange system comprises that the last piece of tube foil that was closed during the last filling, together with the elastic ring that was used, is wrapped in the first pack from the new supply of tube foil and can be removed without the filling head being exposed to the outside air.
