A portion dispensing system including a portioner configured with a controller. The portioner includes a piston configured to move within a container and force product in the container out of a nozzle opening. The controller controls the piston to dispense an input product weight and can detect the weight of dispensed product. The controller can adjust the piston to provide different weights of dispensed product and can provide pullback to substantially provide accurate dosing and eliminate product from oozing out of the nozzle opening.

A liquid filling device is provided, including: a barrel, a piston assembly and a force accumulating assembly. The barrel defines an axial direction and includes a liquid storage space and a through hole communicated with the liquid storage space. The piston assembly includes a piston and a push rod connected with the piston, and the piston is axially movable and is disposed in the liquid storage space. The force accumulating assembly is disposed between the barrel and the piston assembly, and when the force accumulating assembly accumulates force, the piston is driven by the force accumulating assembly to move and push a liquid in the liquid storage space. Therefore, the liquid filling device can fill the liquid automatically, which is laborsaving.
