Abstract: An airflow drying device includes a granulated substance introduction portion, a dry process portion, and a product ejection portion. The granulated substance introduction portion includes a granulated substance inlet into which granulated substances are to be put, and a hot air inlet into which hot air is to be supplied. The dry process portion includes a loop pipe. The loop pipe is positioned laterally in a horizontal direction, and is able to dry granulated substances. The product ejection portion includes a cyclone collector where the granulated substances are collected after being dried through the loop pipe.

Abstract: A drying device 1 is an airflow continuous drying device, and includes a granulated substance introduction portion 11, a dry process portion 12, and a product ejection portion 13. The granulated substance introduction portion 11 is a stainless steel pipe 21, including a granulated substance inlet 22, into which granulated substances are put, and a hot air inlet 23, into which high-pressure hot air is supplied. The dry process unit 12 includes a loop pipe 25, which is made by winding a stainless steel pipe. The loop pipe 25 is arranged laterally in the horizontal direction, and is able to dry granulated substances in a highly efficient manner without turning the substances into powder. The product ejection portion 13 includes a cyclone collector 26, where the granulated substances are collected after being dried through the loop pipe 25.

Abstract: A spray gun (1) forms a desired spray pattern by atomizing by means of atomizing air (A) a spray liquid which is sprayed from a liquid ejection port (44) opened/closed by a needle valve (4), and jetting pattern air (P) to the flow of spray mist of the atomized spray liquid. A nozzle taper angle (?1) is set in a range of 5° to 15°, and a cap taper angle (?2) is set in a range of 20° to 40°. Atomizing air (A) is jetted from a nozzle insertion hole (58) toward the center of a nozzle (3). Pattern air (P) is jetted in a spreading suppressed region (R) wherein the flow of the spray mist does not spread over an area greater than or equal to a predetermined cross-sectional area, to the flow of spray mist, and as a result, the spray mist is more uniformly sprayed over a wide range.

Abstract: Provided is a highly water dispersible powder which exhibits a high water dispersibility in spite of the inclusion of a poorly water soluble component, and maintains the high water dispersibility stably over time. The highly water dispersible powder includes a poorly water soluble component, a water soluble polymer having a protective colloid effect, and a saponin. The highly water dispersible powder can be produced by a method including: emulsifying a poorly water soluble component in an aqueous solvent under the presence of a water soluble polymer having a protective colloid effect and a saponin, thereby preparing an emulsion; and drying the obtained emulsion.

Abstract: An oral pharmaceutical composition which comprises a polyglycerol ester of an unsaturated fatty acid and a drug which is very slightly soluble in water.

Abstract: Coating method and apparatus, in which jet streams of a high-pressure fluid are ejected in the opposed directions into a pulverization zone in a pulverizer to hit a raw material conveyed by one of the jet streams on the other and thereby pulverize the same, the surfaces of particles of the resultant raw material are coated at the same time that the pulverization is done. The raw material to be pulverized is fed into the pulverization zone with a jet stream or by a mechanical means to be then accelerated by a jet stream therein. A coating material is fed in the same direction in which a jet stream flows, or directly into the pulverization zone.

Abstract: Disclosed is a process for the preparation of an activated pharmaceutical composition containing a solid drug that is scarcely soluble in water, the pharmaceutical composition being characterized in that, when it is administered orally, the drug is readily absorbed to attain its high blood concentration quickly. This process is carried out by providing a solid drug that is scarcely soluble in water, dispersing the drug in water in the presence of a water-soluble high-molecular substance to form a disperse system containing the drug in the form of finely divided particles substantially not greater than 10.mu. in diameter, and then removing the water from the disperse system.
