Improvements to a juice extraction machine, particularly a commercial-scale fruit juice extraction machine that is extremely light and compact for very easy handling and transportation, which is noteworthy for its unusual construction configuration that includes, among other items, a swing-lidded waste-bin on its front whose walls are close to the peeler cups when closed, allowing easy removal of wastes such as pith, pulp and peel when open. The invention comprises a fruit-rack sub-set (1) with a curved concave cross-section whose movement is synchronized with the axle (51) that powers the mobile peeler (2), such fruit-rack (1) being attached to the mobile peeler sub-set (2) through slots (3) and with the machine including a cross-spring (4) attached at the bottom of the feeder/dispenser pipe (5), with such cross-spring (4) having a means of activation (6) located on the fruit-rack sub-set (1)； the improved machine (M) comprises a swing-lidded waste-bin (7) on its front part, with such swing-lidded waste-bin (7) having substantially semi-circular sides (8) close to the mobile (2) and fixed (2B) peelers and with the mobile peeler (2) connected to a gear-motor sub-set (31) and the fixed peeler (2B) concatenate with the filter and piston sub-set (67) assembled in the fixed peeler (2B).
