Abstract: A method and apparatus for flattening fermentable dough while heating the dough to accelerate dough fermentation and a dough crust obtained therefrom such as pizza pies are disclosed. An apparatus for flattening a piece of fermentable dough includes a vertically movable table arranged in a horizontal direction and a heated upper plate arranged above and apart from the table, an driving means connected to the table for moving the table upward and downward, a tray detachably held on the table, a sensor for detecting a position or a speed of the table, and a regulator for controlling a moving speed of the table, wherein the dough placed on the tray is pressed and contacted with the heated upper plate so that the contacted layer of dough is promptly fermented and softened to spread into a flattened dough crust.

Abstract: [Object] To enhance an effect for keeping warm and prevent oxidation deterioration of coffee, serving delicious coffee, and to save energy, suppressing generation of carbon dioxide. [Constitute] A coffee machine 100 for spraying hot water over powder of coffee beans to extract coffee, in which a coffee machine body 10 includes a nitrogen gas generation unit 30 for generating nitrogen gas, and a nitrogen gas supplying part 31 for supplying the nitrogen gas generated by the nitrogen gas generation unit 30 into a pot 60, and the pot 60 included a pot body 61 made of heat insulating material, a cover part 62 for sealing up the pot body 61 and a heater 72 provided in at least one of the pot body 61 and the cover part 62, for heating at least the pot body 61.

Abstract: An apparatus for adding humidity to gas having the pressures and flow rates adjustment means for adjusting degree of humidity easily and precisely. The hollow-fiber membrane 1 for the subject gas passing therethrough, the closed enclosure 4 for maintaining the water element containing liquid 5 in contact with the hollow-fiber membrane 1 while maintaining the water level at a specified level 11, the subject gas passing internal hollow-fiber membrane 1, and, pumps 10 (P1, P2) connected to the inlet 8 of hollow-fiber membrane and inlet of the closed enclosure 4, and valves (V1, V2) are connected to the pumps respectively.

Abstract: A brick-oven includes a reduced emission of smoke and odor generated from the brick-oven. A brick-oven includes a catalyst layer in a smoke and odor removing filter in a tubular smoke exhaust section. In one example, a heater is provided in the vicinity of the catalyst layer of the catalyst treatment section of the smoke and odor removing filter.

Abstract: An air elements separating apparatus having a plurality of hollow-fibers for separating nitrogen containing gas and oxygen containing gas having a flexible structure, and an outer sleeve having a flexible structure for covering the plurality of the hollow-fibers member and an opening for releasing the oxygen containing gas separated by the plurality of the hollow-fibers member wherein the plurality of the hollow-fibers member and the outer sleeve member are kept airtight, and the opening is formed in the vicinity of the compressed air intake end, wherein the plurality of hollow-fibers member is made of a resin having a flexible property such as polysulfone or polyimide, and the outer sleeve member is made any one of a metal formed in bellows, resin, rubber or fabric.

Abstract: To provide a method and apparatus for flattening fermentabl dough while heating the dough to accelerate a dough fermentation and a dough crust obtained therefrom such as pizza pies. An apparatus for flattening a piece of fermentable dough, comprises a vertically movable table arranged in a horizontal direction and a heated upper plate arranged upwardly apart from the table, an driving means connected to the table for moving the table upward and downward, a tray detachably installed on the table, a sensor for detecting a position or a speed of the table, and a regulator for controlling a moving speed of the table, wherein the dough placed on the tray is pressed and contacted with the heated upper plate so that the contacted layer of dough is promptly fermented and soften to spread into a flattened dough crust.

Abstract: A control device for a DC motor driving a diaphragm pump including a pulse generating integral circuit and a variable voltage setting integral circuit. The variable voltage setting integral circuit sets a pulse-base voltage at a level such that the DC motor is not rotated when no pulse is applied, thereby a high voltage overshoot generated at the rising and the falling point of an electrical pulse is restricted. Discharge of the diaphragm pump is accurately regulated by means of modifying frequency, voltage, and duty ratio of the pulse.

Abstract: A heat-reserving container for pizza comprising a disc case having a flat circular portion, with a resin-made heat reservoir stored therein is disclosed. The entire surface, of the pizza can be in contact with the flat portion of the heat-reserving container. Also disclosed is a furnace for the above-mentioned heat-reserving container for pizza comprising heating plates each having an interval capable of storing the heat-reserving container for pizza to form multi-layered racks, each heating plate having a heater accommodated therein whose temperature is controlled individually, which can be securely inserted into the furnace body and is heat-reserved as well as the defective movement of the limit switch can be prevented.
