Abstract:

A method is provided for producing a soluble coffee extract which, when reconstituted, produces an intensified in-cup brew color without altering the flavor of the cup of coffee. The method includes heating a coffee extract at a temperature and for a time selected to produce an intensified color coffee extract without altering the flavor of the coffee. The intensified color coffee is either immediately dried to form dried intensified color coffee or cooled while in the liquid state. The soluble coffee produced by this method has intensified color while its flavor remains unaltered. As desired, the soluble coffee may be packaged as an instant coffee, combined with traditional soluble coffee, incorporated into a liquid coffee product or combined with sugar, creamer, and flavors to form various soluble coffee products. Alternatively, the coffee exact may be directly incorporated into a ready-to-drink or a concentrated liquid coffee product without undergoing a drying step.

Abstract:

An electrical heater has first and second heater elements, each having a hairpin-shaped metal tube with an upstream and a downstream leg and tube ends adjacent each other. An electrical resistance wire surrounded by insulation powder extends through the tube. Electrical terminals join to the wire and protrude from each of the tube ends. Conduits enclose the upstream and the downstream legs of the heater elements, providing a continuous annular flow path. A manifold has heater element passages for end portion of the legs. An inlet passage in the manifold leads from an exterior portion of the manifold to the annular flow path surrounding the upstream leg of the first heater element. A transfer passage within the manifold leads from the annular flow path surrounding the downstream leg of the first heater element to the annular flow path surrounding the upstream leg of the second heater element.
