Abstract: A strainer device that collects a filtered object even when the strainer device is used with an object to be strained that is low in water content and highly adhesive, via softening by heating in superheated steam. The strainer device has an inner surface that is circular in cross section, surrounds a strainer vessel, and is supported so as to be rotatable about a central axis thereof; a scraping member that is disposed at a predetermined position along the inner surface of the cover body and scrapes the filtered object adhering to the inner surface when the cover body is rotating; the strainer vessel and the cover body rotate. When the strainer vessel is rotating, the filtered object pushes out of the filtering hole and adhers to the inner surface of the cylindrical cover body and is scraped off at the predetermined position on a circumference along the inner surface.

Abstract: Operating a strainer using centrifugal force generated by the rotation of a bottomed cylindrical vessel having filtering holes in a side surface. The strainer can eliminate the clogging of the filtering holes and maintain the optimal straining effect while maintaining the optimal pressure and duration of pressing food ingredients. The strainer catches a filtrate discharged through the filtering holes of the bottomed cylindrical vessel to the outside of the vessel while rotating the bottomed cylindrical vessel, which contains an object to be strained input therein, in a predetermined rotation direction at a first rotation speed, rotating the rotary pressers in the same rotation direction as the bottomed cylindrical vessel at a second rotation speed different from the first rotation speed of the bottomed cylindrical vessel by a predetermined speed difference.

Abstract: [Problem to be solved] To provide a method for operating a food mill and an automatic food milling apparatus suitable for various foodstuffs heated and softened using superheated vapor are milled by passing the foodstuffs through a strainer while maximally suppressing destruction of cells of the foodstuffs, to continuously manufacture puree with original colors, odors, tastes, and nutritional values kept unchanged. [Solution] A rotation speed difference between a upper mortar and a lower mortar is used to crush and ground ingredient foodstuffs by a shearing force between the upper mortar and the lower mortar, and a conical recessed surface of the lower mortar is utilized to separate the crushed ingredient foodstuffs into filtered foodstuffs and residues by a centrifugal force resulting from rotation of the lower mortar so that the filtered foodstuffs and the residues are collected in a filtered foodstuff collection unit and a residue collection unit, respectively.

Abstract: This invention provides a process for producing biodiesel fuel from vegetable or animal oils and fats or wastes thereof and methanol that does not use a catalyst and does not generate glycerin as a by-product. In this process, vegetable or animal oils and fats or wastes thereof are mixed with methanol, and a methanolysis reaction is carried out at a reaction temperature of between 370° C. and 500° C., a reaction pressure of between 20 MPa and 60 MPa, and a reaction period of between 4 minutes and 12 minutes without the use of a catalyst. This invention also provides biodiesel fuel that is mainly composed of fatty acid methyl esters, monoacylglycerol, and diacylglycerol.

Abstract: In a soil processing method of the present invention, a microwave radiator is made to move into soil, and microwaves are thereafter radiated from the microwave radiator to soil to be processed. As a method for making the microwave radiator move into soil, a method in which an underground mover incorporating the microwave radiator is made to move underground while making a cultivator move underground by means of a underground-moving claw mechanism similar to a chisel or subsoiler, a method in which the microwave radiator is vertically thrust into and drawn out from soil by a power arm, or a method in which the microwave radiator is vertically thrust into and drawn out from soil by using one of various vertical excavation devices may be used. According to the present invention, the influence of microwaves on soil in a deep region not easily influenced by microwave radiation to a farm surface can be effectively improved to ensure that various functions useful in agriculture, e.g.
