Abstract

A system and a process for producing cold brew coffee are provided. The system and method include the use of an extraction tank adapted to receive ground coffee beans therein. Water is pumped into the extraction tank. A back pressure control valve is provided so as to pulse the back pressure within the tank. This pulsed back pressure increases turbulence within the tank. Combined with the flow rate and pressure within the tank, the turbulence allows for cold brewed coffee concentrate to be produced in a much quicker time than associated with prior art methods. A number of extraction tanks may be provided in the system of the present invention so as to increase yield.

Dependent claims

A system for producing cold brew coffee, the system comprising an extraction tank having an interior volume adapted to receive ground coffee beans therein;

a ground coffee inlet opening to said interior volume of said extraction tank so as to allow ground coffee to be introduced into said interior volume, said ground coffee inlet opening adjacent an upper end of said extraction tank;
a water inlet communicating with said interior volume of said extraction tank, said water inlet adapted to allow water to flow into said interior volume of said extraction tank, said water inlet opening adjacent a lower end of said extraction tank;
a coffee outlet communicating with said interior volume of said extraction tank, said coffee outlet opening adjacent the upper end of said extraction tank;
a pump cooperating with said water inlet so as to pump water under pressure through said water inlet such that the water flows upwardly through the coffee in the extraction tank;
and
a back pressure control valve in cooperation with said coffee outlet so as to control water pressure within said extraction tank.
