  • Patent number: 6968125
    Abstract: An electric heater for industrial liquids comprises a plastic flat box that contains a stainless steel pressure vessel holding a number of parallel electrical heating rods. These heating rods are interlaced with shorter “I” shaped Teflon rods which generates a tube-like space around the heating rods. Spiral grooves in the symmetrical concave faces of the Teflon rods promote a spiraling turbulent flow. The general liquid flow from the liquid inlet meanders around the parallel heating rods for optimal heat transfer. The heater can be mounted horizontally or vertically on the side of a lab bench or a vessel for floor space conservation. The flow speed of the liquid, its specific heat, the number of heating elements with their individual power rating determine the heating profile of liquid temperature versus cumulative length of the flow path which is important to prevent the liquid from reaching the boiling point. This arrangement allows for design flexibility and scalability in heating capacities.

    Abstract: An electric space heater uses the heat generated by quartz-halogen lamps to heat air which may be supplied to heat a local space. The heater conducts air through a heater enclosure in which the lamps are installed. The air path is parallel to the longitudinal axis of the lamps. The air is warmed by conduction from the surface of the lamps and from heated walls surrounding the lamps and which form the air flow path. The walls are heated by radiation from the lamps. The flow path for the heated air and the placement of the heated walls substantially isolate the outer portion of the heater enclosure from the heat generated by the lamps to maintain the temperature of the outer surface of the space heater at or near ambient temperature. The walls also confine the light generated by the lamps to the interior of the space heater. The air flow through the space heater is assisted by an electric fan.

The noodle cooker comprises a hot-water boiler which is divided into several water storage spaces, for example four, and which allows the supplied water to flow from space to space, and where each storage space is equipped with its own heater. The water supplied to the first storage space is heated by the heater and then moves to the next storage space. The hot water is finally supplied from the last storage space through a hot-water supply pipe to a processing section where the ingredients are processed. If new water is supplied to the first storage space equal to the amount of water which was supplied from the last storage space, the temperature of the hot water in the last storage space does not drop very much due to the fact that there are several storage spaces.

  • Patent number: 5054108
    Abstract: A heater for heating dionized water and other liquids which may be very aggressive solvents, the heater constituting one or more heating units having an external cylindrical housing of PTF Teflon or similar material and closed at each end with headers of similar material which contain ports for ingress and egress of the fluid. A concentric inner tubular member of polysilicon surrounds one or more infra red heating elements which, when energized, radiate intense heat into the chamber within the inner tube. This tube acts to confine and reflect the heat back into the chamber thereby heating the liquid to a high temperature very quickly. Relatively little heat passes through the wall of the inner tube to the surrounding chamber. Liquid is directed into the outer chamber, across the length of the inner tube, through a passage at the opposite end and into the inside chamber. The flow across the other surface of the inner tube is warmed somewhat but insufficiently to damage the outer tube.
