Abstract:

A modified model of the prototype submarine coffee urn was developed and evaluated. It incorporated automatic siphoning, single-acting preset thermoswitches, and a new safety valve to eliminate boiler pressure relief and steam blowoff during normal brewing operations. The semiautomatic pour-over system incorporated into the design of the urn operated satisfactorily. It will eliminate the watch dog type of coffee brewing required with the prototype submarine coffee urn. The urn fulfilled the military specification requirement for extraction, while exhibiting improved pour-over and leaching temperatures, compared to the prototype urn. It was recommended that a low-water cut-off mechanism be incorporated into the design of the urn, in addition to an improved safety valve, to eliminate all blow-off steam into the gallery. Author
