摘要:
This invention is concerned with a distributive ejection apparatus for liquid material in a freeze-drying apparatus for foodstuffs, medicaments, etc., wherein the liquid material adjusted from the starting material for foodstuffs, medicaments, etc. is caused to freeze onto the inner wall surface of the upright cylindrical tube, and the distributive ejection of the liquid material onto the tube at the time of its freeze-drying by sublimation of the moisture content in the material under the vacuum condition may be done in the state of supplying the liquid material over the entire surface of the inner wall surface of the tube with a substantially uniform thickness. A cylindrical wall a protruding upwardly of the jacket 2 for circulation of heat medium, provided on the outer periphery of the tube 1, is disposed on the upper end side of the upright cylindrical tube equipped on a freeze-drying apparatus w, in the form of extending the peripheral wall of the tube 1; then, onto this inner wall surface of this cylindrical wall, the liquid material is ejected from the distributive ejection nozzles 70 equipped on the downstream side of the tube passageway 5 for feeding the liquid material is sputtered, and the thus ejected liquid material is rendered uniform in the circumferential direction on and along the inner wall surface of the cylindrical wall a, and, while it flows down, in this state, on the inner surface of the cylindrical wall a, it is made to flow onto the inner wall surface 1a of the tube 1 which constitutes the freezing surface of the liquid material.

Disclosed is a freeze-drying apparatus for foodstuffs, medicaments, etc., wherein liquid material is directly and distributively poured into upright cylindrical tubes, then, in its isolated state from external atmosphere for perfect sterilization, the liquid material is frozen with uniform thickness onto inner wall surface of the tubes, with further possibility of uniform heating of the freeze-dried layer. The main body of this apparatus is constructed with upright cylindrical tubes for freezing liquid material onto inner surface of tubes and jackets to surround the outer periphery of each of the tubes in a substantially concentric cylindrical shape, within which to circulate heat medium; then, a duct communicating to the vacuum exhaust system is connected to the upper end side of these tubes, while, a recovery chamber provided with valve is connected to the lower end side of tubes; and an inlet port is defined for feeding liquid material into inner cavity of tubes.

Provided are a floating structure fluid dynamic force use system and a wind-propelled vessel which uses the system whereby it is possible to compensate for overturning moment due to fluid dynamic force and to alleviate both tilting and size increases of a floating structure. A floating structure fluid dynamic force use system (1) comprises an assembly (12) which extracts energy from wind or water, and a floating structure (13) which supports the assembly (12). The assembly (12) comprises a wind receiving part (10) which receives fluid dynamic force, and a support column (11) which supports the wind receiving part (10). The assembly (12) is positioned with the center of gravity (15) thereof below the water line and is supported to be capable of tilting in an arbitrary direction upon the floating structure (13).
