A machine for preparing espresso drinks from ground coffee packaged in coffee pods (C), comprising an opening and emptying device (4, 10, 11), for opening and emptying in a dry condition coffee pods (C) of the ground coffee (P) contained therein, an espresso extraction block (E) to which the ground coffee (P) coming from said opening and emptying device is supplied to dispense an espresso drink, a coffee dregs container (F) for the collection of the spent coffee dregs (P.sub.E) coming from said extraction block (E) and an empty pod container (A) for the collection of the empty coffee pods (C) coming from said opening and emptying device.

An automated self-cleaning frothing appliance includes: a housing having a base, a tower extending upwardly from the base, and a canopy extending from an upper portion of the tower above the base; a vessel mounted beneath the canopy, the vessel having an outlet at a lower end; a frothing tool extending from the canopy into the vessel; a first fluid pathway in the housing to receive water from a water source and deliver water into the vessel; a valve positioned to selectively open and close the outlet to the vessel; a valve-opening mechanism attached to the housing to selectively open and close the valve; a drain positioned beneath the outlet to receive water draining from the outlet; a second fluid pathway routed from the drain to deliver water to an external receptacle; and a controller operatively connected with the drive unit, the first fluid pathway and the valve-opening mechanism.

A beverage brewer spray apparatus includes a lid, dispersal members, and a skirt. The lid has an obverse and converse surfaces. The dispersal members extend from the converse surface of the lid at open proximal ends of the dispersal members. The skirt has a proximal end fixed to and extending outward from the converse surface of the lid. Each dispersal member has a sidewall and a distal end defining an interior of the dispersal member. The sidewall has apertures arranged in a distal section of the sidewall. The lid has through-holes formed between the obverse and converse surfaces, and the dispersal members are fixed to the converse surface such that the through-holes provide fluid communication from the obverse surface of the lid to the apertures through the interiors of the dispersal members. The apertures are configured to direct liquid outward from the dispersal members.

The invention relates to a method for preparing a beverage and to a beverage preparation device (1), such as a beverage dispenser, for simpler and more efficient sanitization of water. The beverage preparation device (1) comprises: a buffer tank (2) having a tank body for storing an amount of water, a recirculation line (20) configured to allow water circulating out of and back into the buffer tank (2) to form a recirculation path together with the buffer tank (2), a UV lamp (40) arranged for irradiating UV light at a position along the recirculation path to sanitize the water, a cooling unit (3) for cooling the water within the buffer tank (2), a discharge line (23) for discharging the water from the buffer tank (2) via a discharge outlet (24), and a pump (26) for selectively circulating water along the recirculation path or the discharge line (23) towards the discharge outlet.

Heat transfer device (10) for heating a fluid or a fluid foam on demand comprising a path (30) through which the fluid or the fluid foam circulates and at least one layer (11) made of a thermally conductive material, the path (30) being in contact with the layer (11) in such a way that when the layer (11) is heated it transmits heat to the fluid or fluid foam as it circulates through the path (30), wherein the path (30) and the part of the layer (11) in contact with said path (30) are detachably configured so that they are made accessible for being cleaned.
