  • Patent number: 12084333
    Abstract: A beverage dispense system for a countertop having a water inlet including a solenoid valve and a beverage concentrate inlet to which a bag-in-box containing a supply of liquid coffee concentrate is attached. A beverage dispense font is mounted on the countertop. A water conduit connects the water inlet with the dispense font. A separate liquid beverage concentrate conduit connects the beverage concentrate inlet with the beverage dispense font. An electric syrup pump pumps liquid coffee concentrate from the bag-in-box to the end of the dispense font. A control unit controls the separate delivery of water from the mains water inlet and/or liquid coffee concentrate to the end of the beverage dispense font. Where water and liquid coffee concentrate are delivered, they will mix in the beverage receptacle.

  • Publication number: 20240032726
    Abstract: A weighing device (11) is incorporated into an espresso coffee machine (10). The weighing device (11) is located in a drip tray (12) of the espresso coffee machine (10) under a group (13) thereof. The weighing device (11) has a display (not shown) for indicating the weight of a shot as it is being delivered and the elapsed time from the start of delivery. A start extraction button (not shown) on a pressure adjusting handle (24) mounted on the group (13) is connected to the weighing device (11). In use, movement of the pressure adjusting handle (24) initiates delivery of a shot from the group (13), which movement also activates the weighing device (11) in one mode of operation. Thus, a barista can use the weighing device to calibrate the “perfect shot” using the weight and time measurements displayed thereon.

  • Patent number: 10080462
    Abstract: A sprayhead for a pour over coffee brewing machine for delivering hot water to coffee grounds held in a brew basket therebelow, has a housing with a water inlet at one end thereof, which is connectable to an intermittent source of hot water. A holding chamber for accumulating a quantity of hot water therein is located within the housing and is connected to the water inlet. A dispensing chamber is located within the housing and below the holding chamber, in use. A bell siphon located in the holding chamber delivers the accumulated quantity of water from the holding chamber to the dispensing chamber, and then to the coffee grounds, once the water level in the holding chamber rises above an open end of a siphon tube.

  • Patent number: 9895019
    Abstract: A device for use in the preparation of beverages, for managing the draw-off of water from a source of hot water comprises a chamber having a base, a cylindrical wall mounted on the base and a top section. An inlet and a return outlet are mounted in the base, and both the inlet and the return outlet are connectable to a source of hot water. Three draw-off outlets are also mounted in the base. The return outlet consists of a hollow tube section, which passes through the base to form a stand pipe. In use, hot water is introduced into the chamber through inlet and the chamber is orientated such that return outlet is positioned above the inlet. The inlet flow rate is equal to or greater than the draw-off flow rate, and any excess volume of hot water in the chamber is returnable, to the source of hot water, through the return outlet, thereby creating a constant head of water above the draw-off outlets.
