<p>A brewer unit for a hot drinks dispensing machine includes a brewing cylinder having a pressure-applying piston and into which tea leaf or ground coffee and hot water are introduced, the base of the cylinder being a filter screen. The base and cylinder walls are movable relative to each other between a position of sealing engagement and a spaced-apart position and a wiper arm is positioned externally of the cylinder adjacent to the filter. In use, the piston applies pressure to the cylinder contents while the base and cylinder are in sealing engagement, whereby brewed beverage is forced through the filter, and the cylinder and base then move apart to allow the wiper arm to traverse the filter in the space formed, to remove spent tea leaf or coffee grounds therefrom in readiness for the next brewing cycle. <IMAGE></p> |
