1. An expansion chamber useful for the substantially adiabatic expansion of ambient-temperature pressurized anhydrous liquid ammonia to produce separate cold ambient pressure streams of gaseous anhydrous ammonia and liquid anhydrous ammonia and application of said cold ambient pressure liquid anhydrous ammonia to fermentable plant material comprising a closed expansion chamber provided with two outlets, one outlet being useful for the withdrawal of cold gaseous anhydrous ammonia and the other outlet being useful for the withdrawal of cold anhydrous liquid ammonia and conduit means associated with said expansion chamber for introducing thereinto a stream of ambient-temperature, pressurized liquid anhydrous ammonia for expansion therein to produce therein cold gaseous ammonia and cold liquid ammonia at substantially ambient pressure, and a distribution conduit for uniformly applying the ambient pressure cold liquid anhydrous ammonia withdrawn from the expansion chamber to fermentable plant material.
