LIQUID FOOD OR BEVERAGE PREPARATION MACHINE

An integrated in-line heater (1,8,9) for a liquid food or beverage preparation machine, in which liquid is circulated through said heater and then guided into a brewing chamber (7) for brewing a food or beverage ingredient, for instance within a pod or capsule (7''), supplied into the brewing chamber. An upstream part of the brewing chamber may be formed by the heater. One or more electric components (5,60,70,75) may be incorporated into the heater and rigidly connected to a printed circuit board (50). The heater may have a tubular inner core (9) that is eccentric with respect to a tubular or prismatic outer member (8) which form together a helicoidal heating chamber (4) of variable cross-section (4',4").
