A beverage dispenser and method of operation, in which incoming water for beverage preparation is heated by a liquid-to-liquid heat exchanger. The heated water may be mixed with cold water using controlled valves, to generate a selected temperature stream. This controlled-temperature stream may be mixed with beverage concentrate or sprayed over coffee grounds to brew fresh coffee.

A method and system for brewing a desired volume of coffee at a selected brew time, in which a volume of water corresponding to the desired volume of coffee is heated and directed into contact with coffee grounds in a brewing chamber. Contact between at least a portion of the heated water and the coffee grounds is maintained for approximately the selected brew time to form brewed coffee. The brewing time, however, is substantially independent of the desired volume of coffee to be brewed and is controlled by control of the rate at which heated liquid flows into or out of the brewing chamber. At the expiration of the brewing time, brewed coffee is released through an opening in the brewing chamber and into an underlying receptacle.

Various forms of apparatus for preparing and dispensing beverages, preferably based on coffee, can receive instructions from a customer and deliver the beverage automatically. The apparatus is preferably capable of fully automatic cleaning in a cleaning cycle in which a cleaning agent is flushed through the lines, and the apparatus is preferably arranged to ensure that not only are the lines cleaned properly but that no cleaning agent can be dispensed. The apparatus includes a brewer assembly having a chamber in which freshly ground coffee can be introduced and either espresso or filter coffee can be automatically prepared by passing hot water through the chamber and removing the spent coffee grounds . The coffee may be stored as coffee beans in sealed containers that can automatically be pierced to release the beans which are ground immediately before preparation of the beverage . The apparatus also includes a cup-size detector for ensuring that the customer offers a cup to the apparatus that is of a size appropriate to the beverage selected.

A solid burnable fuel composition which contains a major proportion of spent dried coffee grounds is described. The fuel composition includes at least 50% dried spent coffee grounds and a combustible wax which are mixed together and compressed into a suitable shape for combustion. The fuel composition may further include a small amount, 10% or less, of a coking agent useful to control burn rate and to prevent cracking of compressed fuel during combustion. Small amounts of cellulosic material may also be incorporated to improve the structural properties of the composition. Due to its superior heat and flame production, dried spent coffee grounds are an excellent fuel source for processed fuel products such as fire-logs and fuel pellets. The advantage is a hotter, cleaner burn which produces less soot and smoke, releases fewer harmful pollutants and provides a brighter flame over a longer period of time.

An improved coffee brewer and brewing method are provided for producing brewed coffee with improved flavor. The coffee brewer includes a brew basket having jet ports connected to a source of heated water and positioned to deliver hot water streams into the brew basket at a location beneath the level of coffee grounds contained therein.

The desired amount of coffee grounds, tea leaves, herbs or other beverage making material is placed in a chamber of glass vessel located on a moveable table top in its lowered position. The table top is then elevated until the upper edge of the vessel seals against a top seal. With the top sealed, the desired amount of water of about 185°-212° F. is introduced into the chamber through a port in the top. Thereafter, a vacuum is drawn in the chamber and is held within the range of about −5 to −20 Hg in. Using an external heat source, the brewing liquid is maintained at about 185°-212° F. Alternatively, the vacuum can be pulsed by turning it on and off several times during the brewing cycle. After the beverage has brewed for the desired amount of time, the heat and vacuum are removed, the chamber is returned to atmospheric pressure and the table top is lowered to release the vessel. The contents of the chamber are then strained to remove solids from the beverage.

The invention provides an hourglass shaped apparatus for cold brewing coffee, comprising a brew chamber, and extract chamber and a middle unit connecting the brew and extract chambers. The extract and brew chambers comprise two ends of the hourglass shaped middle unit. The brew chamber houses a free-standing self-contained filter containing coffee grounds inside a water-permeable barrier. Water is poured into the brew chamber to generate coffee extract through cold water infusion. After the brewing process, the apparatus is inverted, and the coffee travels into the extract chamber through the middle unit for dispensing. Coffee brewed in this manner is less acidic and more flavorful than the conventionally hot-brewed beverage. All the components of the apparatus, the filter, the brew chamber, the extract chamber, and the middle unit, are detachable.

A coffee maker contains a siphon tube for discharging hot water from a heated reservoir to a container for coffee grounds. Flow through the siphon tube is initiated by pressurizing the air space in the heated reservoir with an air pump. A siphon flow of hot water through the siphon tube to a coffee grounds container then continues without pressurization. The flow is ended when the desired volume of coffee is brewed.

The brewing system disclosed herein includes a reservoir for storing ambient temperature water used to brew coffee. A pump displaces water from the reservoir to a heater tank for heating thereof before delivery to a coffee cartridge in a brew head. Initially, the pump displaces a small volume of heated water under pressure through a rotating inlet needle to pre-wet and pre-heat coffee grounds in the cartridge. The pump then pumps a fairly consistent and larger volume of heated water under pressure to the cartridge via the spinning needle. Near the end of the brew cycle, the pump pumps a small quantity of air to purge the brewer head conduit, the brew head check valve, and the spinning needle, and to purge coffee from the coffee cartridge and to reduce dripping.
