An extractor for separating the juice and juice sacs from a citrus fruit that includes a lower cup (16) for supporting a single piece of citrus fruit and an upper cup (14) disposed vertically above the lower cup with the upper and lower cups moveable relative to each other in a vertical direction so as to cooperate to squeeze the piece of citrus fruit placed therebetween. An upper cutter (30) is provided for cutting a plug in the citrus to permit the separation of the peel from the juice and the juice sacs, while a lower cutter (24) is provided for cutting the plug to allow the juice and juice sacs to exit therethrough when the fruit is squeezed between the upper and lower cups. A strainer tube (26) is vertically oriented beneath the lower cup and lower cutter, with the strainer tube having a plurality of circumferential slots (38) along its working length (36). A plunger tube is slidingly received within the strainer tube for forcing the juice and juice sacs outwardly through the slots and the strainer tube into a separate reservoir. The slots in the strainer tube may be of equal width and evenly spaced apart or of varying widths. In any event, the slots are preferably between about 0.5 and about 3 millimeters in width.

Cette invention concerne un presse-agrumes conçu pour séparer le jus et la pulpe d'un agrume, comprenant une coupelle inférieure (16) recevant un fruit entier et une coupelle supérieure (14) disposée à la verticale de la coupelle inférieure, les deux coupelles pouvant se déplacer l'une par rapport à l'autre selon une direction verticale de manière à presser le fruit placé entre elles. On trouve un couteau supérieur (30) servant à découper un bouchon dans le fruit, ce qui permet de séparer la peau d'une part, le jus et la pulpe d'autre part, et un couteau inférieur (24) qui tranche ledit bouchon et permet au jus et à la pulpe de s'échapper lorsque le fruit est comprimé entre les coupelles supérieure et inférieure. Sous la coupelle inférieure et le couteau inférieur se trouve un tube tamis (26) disposé verticalement qui présente à sa périphérie une pluralité de fentes (38) sur sa longueur effective (36). Un tube plongeur vient coulisser dans le tube tamis et en chasse à force le jus et la pulpe par les encoches dans un réservoir distinct. Les encoches du tube tamis peuvent être équidistantes et de largeur égale ou variable, largeur comprise dans tous les cas de préférence entre 0,5 et 3 mm environ.
