Beverage machine and method for producing coffee-based beverages

Abstract

A beverage machine for producing coffee-based beverages includes a pump supplying pressurized water; a heater heating the water; a brewing chamber, which is fillable with coffee powder; piping in fluid connection with the pump, heater and brewing chamber for conducting pressurized water into the brewing chamber; and a dispensing device dispensing coffee-based beverage produced in the brewing chamber by brewing the coffee powder with the water. The piping has a first feed pipe between the pump and heater and a second feed pipe between the heater and brewing chamber. The second feed pipe has at least a first valve. A cooler is arranged in the second feed pipe downstream of the first valve for cooling water heated by the heater, to enable production of coffee-based beverages having different temperatures, in particular temperatures below 50° C., which allow pouring the produced beverage into a bio-degradable cup made of polylactic acid (PLA).
