OVERPRESSURE VALVE FOR BOILER OF FOOD STEAM TREATING STEAMER

摘要

An apparatus for transferring refrigeration to an object to be cooled without mechanical contact of the refrigerator and object so that vibrational loads are not transferred to the object. The apparatus is characterized in that a fluid transfer medium is caused to circulate in a confined path adjacent the refrigeration source and the object to effect cooling of the object. An apparatus such as disclosed is ideally suited for cooling samples for Mossbauer Spectroscopy.
