Abstract
A coffee machine for dispensing automatically individual cup portions and pot size portions of coffee, as well as dispensing continuous flow of coffee and continuous flow of hot water comprising a housing with a hot water tank, a freeze-dried coffee concentrate hopper, and a mixing assembly for receiving the hot water and concentrate. A heating device is associated with the discharge passage from the hopper to prevent caking of the particles at the outlet, which would interfere with the proper metering of the coffee concentrate.
