The invention relates to a device for drying pourable products, comprising a rotor chamber (1) in which a rotor (2) having a vertical rotor axis (3) is positioned. The rotor (2) has a horizontal central surface and at least along its radially outer third has a conical envelope (22) which is inclined in relation to the axis of rotation (3) at an angle of between 20° and 70° in such a way that the face of the conical envelope (22) having the greater diameter is situated at the top. The envelope (22) has at least partly flat gas passages in the shape of holes or screens. The method provided for in the invention uses the above device for drying pourable products. To this end dry gas is supplied to the surface of the products to be dried during the radial, peripheral circulation of same, without said products being whirled up and subjected to inadmissible pressure, shock and/or friction.

A counterbalanced, dual submarine-type liquid mixer provides a pair of counterbalanced mixing devices that move at opposing ends of a balance bar (40) suspended above the surface of a liquid (10) to be mixed. The bar (40) is able to pivot so as to vertically move its ends (44, 46) alternately between a raised and a lowered position in such a manner that when one of the mixing devices is in a raised position in the liquid (10), the other of the mixing devices is in a lowered position and each of the two mixing devices tends to counterbalance the other.

The invention relates to a device consisting of a rotor chamber (1) in which a rotor (4) having a vertical rotor axis (3) is arranged, where the rotor (4) at least along its radial outer third has the shape of a conical envelope (22), and guide vanes(11) for circulating the starting material or product. The guide vanes (11) are arranged above the plane (9) of the upper edge (5) of the rotor (1) and statically against the inner wall (6) of the rotor chamber (1). Their cross-section in relation to the rotor axis (3) substantially has the shape of a segment of a circle or spiral and their inner ends are situated approximately in the central part of the rotor radius. The conical envelope (22) can have at least partly flat gas passages in the shape of holes or screens. The invention also relates to the use of the device for the production of pourable products. According to said method, cores are prepared or a coating layer is deposited on cores.

A pneumatic bioreactor includes a vessel containing a fluid to be mixed and at least one mixing device driven by gas pressure. A first embodiment includes a floating impeller that rises and falls In the fluid as gas bubbles carry it upward to the surface where the gas is then vented, permitting the impeller to sink in the fluid. The floating impeller may be tethered to a second impeller with a flexible member and pulley. The mixing speed is controlled with electromagnets in the vessel acting upon magnetic material in the impeller or its guides. In another embodiment, floating pistons mix the fluid, pushing it through a mixing plate with one or more apertures. In a third embodiment, the mixing device is a rotating drum vvith bubble-catching blades and rotating mixing plates with apertures. The top of the vessel for these mixers may include a closed top and sterile filters.
