Infusion brewer and closed loop filter thereof

An infusion brewer comprising:

• a filter path forming a continuous loop around a plurality of rotary shafts, the plurality of rotary shafts being operable to cycle a continuous loop filter along the filter path, the filter path having a steeping area and surrounding a vacuum chamber;
• an infusion enclosure having a bottom opening positionable into an infusion position against the continuous loop filter at the steeping area;
• and
• a filter support having an infusion aperture at the steeping area, wherein the filter support is provided in the form of an upper wall of the vacuum chamber;
• wherein, in the infusion position, the continuous loop filter is sandwiched between the infusion enclosure and a portion of the filter support surrounding the infusion aperture,
• wherein the filter path has a corner edge around a corresponding one of the rotary shafts following the steeping area, the corner edge leading to a first chicane portion formed with at least two further ones of the rotary shafts in a sequence of an outer radius, an inner radius, and a second outer radius;
• wherein the filter path further has a second chicane portion around at least three corresponding ones of the rotary shafts following the first chicane portion,
• wherein the first chicane portion and the second chicane portion form opposite laterally-opened V-shapes, and
• wherein a driving one of the rotary shafts is engaged internally with the filter path between the first chicane portion and the second chicane portion.
