摘要:
The present invention has an object to provide a stirring processing apparatus and a processing method to realize excellent processing of a fluid regardless of the properties of the fluid. The stirring processing apparatus is provided with the stirring blade 22 and the stirring chamber 18 provided with the screen 23, wherein the apparatus performs, under a state in which the stirring chamber 18 is disposed in a fluid to be processed, a process of applying a shear force to the fluid by a relative rotation between the screen 23 and the stirring blade 22. The stirring chamber 18 is provided with the suction opening 24 to suck the fluid from outside to inside and the ejecting opening 25 to eject the fluid from inside to outside; these openings being disposed above and below. The suppressing body 31 to control a flow of the fluid is disposed between the suction opening 24 and the ejecting opening 25. The suppressing body 31 is, for example, in the form of a cylinder, and is interposed between the suction flow 26 and the ejecting flow 27, thereby suppressing interference between the two flows.
摘要:
In a process for dispersing, mixing or homogenising solid/liquid and/or liquid/liquid mixtures, the dispersion or emulsion to be homogenised is introduced into a rotating grinding chamber (5) at least partly filled with grinding bodies and bounded by at least two rotary wall components (2, 4). The dispersion or emulsion to the homogenised is taken through the grinding chamber (5) transversely to the axis of rotation (3) of the wall components (2, 4). In a device for implementing the process with a grinding chamber (5) in which there are grinding bodies, the grinding chamber (5) is bounded by at least two wall components (2, 4) which can be rotated and it has at least one inlet and/or outlet aperture (15, 16) on its sides facing and away from the axis of rotation (3).
摘要:
The present invention relates to a solid dispersion characterized in that it comprises carbamic acid 3-(4-benzyloxy-phenyl)-isoxazol-5-ylmethyl ester as an active ingredient and a water-soluble polymer having a glass transition temperature lower than the melting point of the active ingredient as a carrier, and it is prepared via melt extrusion. The solid dispersion of the present invention remarkably increases the solubility and dissolution rate of the active ingredient which is an insoluble drug to efficiently improve the bioavailability when it is orally administered.

摘要:
A rotating stirring device for generating substantially narrow distribution of energy dissipation rate and avoiding presence of Taylor vortices is disclosed. The device comprises an outer member (1) such as a cylinder with cross-section of circular shape and an inner member (2) with cross-section of equilateral or inequilateral polygon shape with curved cusps. The inner member is preferably concentrically placed within the outer cylinder and rotates. Such device is particularly advantageous as a reactor or mixer for processes where chemical and physical properties are sensitive to the variations in the shear rate and for processes that involve fragile components. The device can be also used to replace Taylor Couette device for the purposes of improving mass transfer and of avoiding separation of components in the gap in the case of presence of differences in density among components.

摘要:
Die vorliegende Erfindung bezieht sich auf ein Werkzeug (1), welches eine Rheologiemessung unterstuützt. Das Werkzeug (1) weist ein im Wesentlichen innen hohles zylinderförmiges Element (2) auf, in dessen Hohlraum ein inneres Werkzeugs zur Rheologiemessung (7) angeordnet werden kann. Das Werkzeug (1) weist Mischelemente (2) sowie Aussparungen in der Mantelfläche des zylinderförmigen Bauteils (2) auf und ist durch einen Antrieb (7) bewegbar bzw. rotierbar. Somit kann das zu vermessende Medium vor der Rheologiemessung durchmischt werden, so dass die Eigenschaften einer homogenen Mischung bestimmt werden können.
