Century Dictionary and Cyclopedia
- n. An apparatus for restoring heat to a previously heated body which has entirely or partially cooled during some stage of a manufacture or process. In a diffusion apparatus for extraction of sugar from beet-roots or from sugar-canes, reheaters are arranged in alternation with diffusers, commonly twelve in number, containing the sliced roots. The hot water for diffusion is directed through pipes connecting the diffusers with the reheaters by means of cocks or valves, and is reheated by passing through a reheater after passing through a diffuser. Thus, through the aid of heat and pressure, the water becomes charged with sugar. See
diffusion apparatus(under diffusion), and diffuse.
- n. A heater for raising the temperature of steam which has been used once and is to be used again, as in the low-pressure cylinder of a compound engine, or which has been cooled by traveling a long distance. Reheating dries and possibly superheats the steam and so lessens the cylinder losses.
“When it comes time to reheat the casserole, the reheater can sprinkle some freshly-grated cheese on top.”
“I have a coffee reheater, blankets and two batteries for the laptop.”
“It is a French-made blender, steamer, defroster and reheater all in one unit.”
“Just before the water enters the reheater D it is caused to pass through”
“Section C-D shows the fan and gives a section through the reheater.”
“The proper mixture of cold and warm water is made, so that the electric reheater can be controlled readily by the resistance in series with it.”
“To provide for more continuous operation and for more exact temperature control, a thermostat has been placed in the duct and is so constructed as to operate some reheater coils beneath the brine-coils in the refrigerating room.”
“This thermostat is set at 60° F., and when the temperature of the air in the duct falls below this point, the reheater system is automatically opened or closed.”
“The more recent method of control by regulating the temperature of the ingoing water by the electric reheater has been much refined and has given excellent service.”
“All the piping, including that under the floor, and the reheater D, are covered with hair-felt and well insulated.”
