Abstract: Seasoning of liquid material containing at least sodium chloride, seasoning components and solvent is dried at a temperature not more than the boiling temperature of the liquid material to generate mixture bodies containing large-diameter spherical bodies and small-diameter spherical bodies. Accordingly, the solvent is not rapidly vaporized, but it is slowly vaporized and components dissolved in water, and particularly sodium chloride is not agglomerated on the surface layer portions of the large-diameter spherical bodies, but kept inside the large-diameter spherical bodies. Therefore, segregation of sodium chloride on the surface layer portions can be suppressed, and deliquescence is reduced. Accordingly, there can be obtained dry powder seasoning which is low in deliquescence under a using state and excellent in storage stability for a long term.

Abstract: The present invention provides a method of accelerating hardening of thermosetting resin and a device therefor such that hardening time is rendered far shorter than in the case of the prior art. By way of a pertinent means, when unhardened thermosetting resin is to be disposed in an atmosphere having a specified temperature for the purpose of hardening, a ceramic plasma spraying plane is formed in at least one portion, or preferably in as large an area as possible, in the above-mentioned atmosphere whose temperature is maintained at a specified level and in which the above-mentioned resin is disposed, thereby causing convective heat existing in the hot air to be thermally converted into far infrared radiant heat radiation from the ceramic plasma spraying plane mentioned above.

Abstract: A continuous drying system for flake-formed or granular solid, of which bottom inside surface is semi-cylindrical and arranged almost horizontally, comprises drying system main body having a supplying means of a drying object at one end thereof and having a discharging means at the other end thereof, and a coil-formed sending apparatus arranged rotatably inside the main body, and a bar-formed or blade-formed stirring member arranged between the sending apparatus transversely. The drying object is transferred by said coil-formed sending apparatus, and a part of the drying object is retreated while stirring by scooping up the drying object with the stirring member along the inside surface of the main body of the drying object. The transfer of the drying object is delayed in comparison with the rotation of the sending apparatus.

Abstract: A sauna device, which achieves the above object and can produce a sauna effect even at low temperatures, includes: a heating device installed on a ceiling surface of a sauna chamber, the heating device including a flat-plate heating body having a heat radiating surface, a suction port on one side of the heating body, a supply port on the other side, and a duct-shaped air heating chamber formed at the back of the heating body; wherein hot air heated in the air heating chamber is blown out of the supply port down to near a floor surface where it is reversed and circulated in the sauna chamber to be drawn into the suction port for reheating; wherein a heat radiating area of the heating device for radiating heat into the sauna chamber is about 30-70% of the area of the ceiling surface of the sauna chamber, and the hot air blown from the supply port has a velocity enough to be able to come close to the floor surface of the sauna chamber.

Abstract: A far infrared radiation heater 33 is disposed on the back of a ceiling of a drying chamber 11. The inside of the drying chamber 11 is evenly heated by the heat emitted from the far infrared radiation heater 33. The drying chamber 11 is provided with air charge means 16 and air exhaust means 17 each communicating with the inside thereof. Outside air is introduced into the drying chamber 11 by means of the air charge means 16. On the other hand, the air exhaust means 17 continuously maintains the inside of the drying chamber 11 in a state of reduced pressure. Thus, objects to be dried which are placed in the drying chamber are dried by heating under reduced pressure while continuously introducing fresh air. Therefore, the present invention provides a system for drying objects to be dried whereby not only can dried products be produced within a short period of time but also the flavor is satisfactorily retained in the dried products.

Abstract: A fish culturing method and a sac-fry pond for practicing the method are disclosed, which utilize irradiation of far infrared rays from above the water surface in a culturing pond and/or from the bottom of the pond to promote growth of fry in water of a relatively low temperature, substantially without raising the temperature of water which is consumed in a great amount.

Abstract: A method of promoting growth of a great number of livestock individuals to the prescribed average weight in a substantially closed house, within a reduced period of time and consumption of feed, at an enhanced rate of survival and at a suppressed degree of variation in the individual growth, which comprises heating the house floor from below and controlling the floor temperature to be substantially constant throughout the floor area, and effecting ventilation across the house substantially without generation of any noise by delivering outdoor air taken in through an intake opening substantially evenly into the house and discharging the air within the house by natural exhaust through an exhaust window. A livestock house for practice of the method is also disclosed.

Abstract: A planar heating element having a thin flat body formed from an insulating thermoplastic resin and electrically conductive powder. The electrically conductive powder is formed in a layer within the thermoplastic resin in the neighborhood of the entire surface of the body. Lead wires within the flat body being positioned near the surface of the body such that the lead wires are electrically connected to said layer of electrically conductive powder. The planar heating element being produced by a method comprising melt-admixing an insulating thermoplastic resin with an electrically conductive powder. The mixture is then extruded, and the extruded body is rapidly cooled.
