Percolator : nm A percolator is a device used to prepare coffee in large quantities. Operating on the principle of percolation (association ofinfusion and infiltration), it consists of a cold water tank, a hot water generator and a filter holder containing the coffee ground. By thermosiphon, the cold water propels the hot water which passes through the coffee. The drink is then pushed towards a more or less large pouring container, placed on a heating plate; the infusion is easily done by gravity at a temperature of around 95 ° C.
