Abstract

L'invention concerne une machine de pressage sous vide à alimentation électrique, comprenant un cylindre de pressage (9), une partie de réception de jus, un piston (10), un mécanisme télescopique à alimentation électrique, une pompe à vide électrique (17) et un corps de machine (7). Le piston coulissant (10) est monté dans le cylindre de pressage (9). Le bord extérieur du piston (10) s'ajuste étroitement au bord intérieur du cylindre de pressage (9). Le piston (10) divise le cylindre de pressage (9) en une cavité de déplacement (2) et une cavité de pressage (13) séparées l'une de l'autre. La surface supérieure du piston (10) est placée dans la cavité de déplacement (2). La surface inférieure du piston (10) est placée dans la cavité de pressage (13). Les aliments tels que des fruits ou des légumes sont maintenus dans un environnement sous vide tout en étant pressés et le jus (notamment l'huile) est également maintenu dans un environnement sous vide lorsqu'il entre dans la partie de réception de jus ou dans un réservoir de réception de jus, ce qui permet d'empêcher le problème de l'état de la technique lié à la décoloration et à la détérioration du jus par l'oxygénation. Par rapport à une machine de pressage de jus en spirale sous vide, le nettoyage est facile (après chaque utilisation, un lavage est nécessaire pour seulement trois composants, à savoir la partie de réception de jus, le cylindre de pressage (9) et le piston (10), alors que la machine de pressage de jus en spirale sous vide nécessite le lavage de sept éléments, à savoir un couvercle d'étanchéité, un cylindre d'alimentation, un arbre hélicoïdal, un filtre cylindrique, une cavité de production de jus, une coupelle de réception de jus, et une coupelle de pâte) et le fonctionnement est facile (seuls les trois composants doivent être montés au minimum, tandis que la machine de pressage de jus en spirale sous vide requiert au moins le montage des 7 composants).
