Volume displacement isobaric quantitative filling system based on cylinder-adjustable piston

Abstract

This utility model discloses a volume displacement isobaric quantitative filling system based on a cylinder-adjustable piston, relating to the field of filling technology. It includes a filling head and a container air chamber. A moving piston is installed within the container air chamber, and the movement of the moving piston forms a variable-sized carbon dioxide air chamber and a wine chamber. The carbon dioxide air chamber is connected to the filling head via a carbon dioxide pressure reserve pipeline, and the wine chamber is connected to the filling head via a wine pipeline. This design is based on the piston-lifting cylinder driving the moving piston, causing the moving piston to move along the container air chamber, forming a variable-sized carbon dioxide air chamber and a wine chamber. Before filling, the wine is quantitatively filled into the wine chamber, and as the wine is filled into the bottle, carbon dioxide is simultaneously drawn from the bottle into the carbon dioxide air chamber, achieving a dynamic balance between wine filling and carbon dioxide emission, thus realizing quantitative filling of the wine.
