    摘要： A scalable process and device for producing a biomolecule, in particular pharmaceutical grade plasmid DNA is described. The process includes the steps of alkaline lysis, neutralization and clarification and can be further extended. For separating the lysate and the precipitate an improved floatation method is disclosed. This method is based on attachment of CO 2 bubbles on the precipitate floc. The CO 2 is released from a carbonate salt during or after neutralization (acidification). The method of the invention is preferably carried out in an automated continuous mode applying devices for lysis and neutralization and a novel device for completely continuous clarification (separation of flocs and clarified lysate).

    摘要： The invention relates to a distributor plate (9) for a falling film evaporator (1-5) the distributor plate (9) including an essentially planar plate member (45) having a multiplicity of distribution holes (46) therein, the distributor plate (9) being adapted to maintain a head of liquid thereon during evaporation to thereby regulate flow and distribution of liquid to be evaporated to calandria (8) via said distribution holes; the distributor plate (9) further comprising a series of overflow conduits (47) for providing additional flow of liquid through the plate during washing the inlets of the overflow conduits being disposed above the surface of the plate member to provide an overflow of wash liquid during washing. The invention also provides a method of operating a multiple effect evaporator in which the effects include the distributor plate (9).

    摘要： The process for producing a powdery anionic surfactant according to the present invention, wherein a powdery anionic surfactant is produced by using an evaporator having a heat transfer wall and rotating blades rotating along the inner surface of the heat transfer wall, which comprises feeding the anionic surfactant in the form of an aqueous slurry thereof having a solid concentration of from 60 to 80 wt.% into the evaporator, forming a film of the anionic surfactant on the inner surface of the heat transfer wall by rotating the blades, and scraping the film from the inner heat transfer wall with the rotating blades and powdering while continuously concentrating and drying the aqueous anionic surfactant slurry.

    摘要： In einem Trockner werden Verteilerkörper von einer zentralen Drehvorrichtung (2) durch eine Zwangsführung zwischen zueinander parallelen Ebenen (8, 9), die aber nicht senkrecht zur Drehvorrichtungsachse liegen, so bewegt, daß die gesamte Wärmeaustauschfläche des Trockners von den Verteilerkörperkanten überstrichen wird. Dadurch ist eine Selbstreinigung der inneren Oberfläche des Trockners gewährleistet, und es tritt bei zu Klumpen neigenden Produkten eine zusätzliche Mahlung auf. Bevorzugt sind als Verteilerkörper gerade Kreiszylinder; sie sind ohne zusätzliche Führung mit geringem axialem Spiel zwischen den parallelen Ebenen frei beweglich.

    摘要： The present invention discloses a ring dryer, comprising a housing, a top cover provided at the top of the housing, and a base provided at the bottom of the housing, and further comprising a feeding system into which the material to be dried flows, a material coating assembly, a material extrusion assembly, a discharging scraper, and at least two cylinders with different radii, wherein each of the cylinders is provided with a heat medium flow path inside, an annular groove is formed between the adjacent cylinders, and a material outlet is provided at a free end of the feeding system; the material to be dried in the feeding system flows into the annular groove along the material outlet; the material coating assembly, the material extrusion assembly and the discharging scraper are movably arranged in the annular groove and can move along the annular groove relative to the cylinders; and a blade of the discharging scraper is respectively in contact with an inner circumferential surface of the cylinder and an outer circumferential surface of the adjacent cylinder. The present invention has the advantages in that the drying area of the material to be dried is increased, and the material to be dried does not need to be vigorously stirred by the components of the present invention so as to reduce friction between the material to be dried and the components, thereby extending the service life.
