500ml/1000ml Semi-Automatic Filling Packing Machine Double Nozzle Rolan ⚙

Working principle
Working principle of SFM series sauce filling machine: It is a semi-automatic piston filling machine. This series of paste quantitative filling machine is equipped with a special three-way filling valve. The cylinder drives the piston to reciprocate to achieve the effect of filling. When the piston twitches, the three-way rotary valve opens the feeding and the discharging valve closes; When the piston is pushed, the feed valve is closed and the discharge valve is opened for filling. And the reed switch is used to control the stroke of the cylinder, and the filling volume can be adjusted.

This series filling machine is a highly versatile, dependable and accurate filling machine capable of handling water thin liquid to highly viscous paste without or with chunks and particles but best for viscous liquid. This pneumatic volumetric filler machine measures and delivers the product to the container by the action of a single piston for each filler head. The piston is drawn back in its cylinder so that the product is sucked into the cylinder. A rotary valve then flips ninety degree between the cylinder and discharge tube on the dispense stroke so that the product is then pushed out of the nozzle instead of back into the hopper.

The volume of the filling chamber in which the piston is operating determines the volume of product delivered into the container. The larger the product cylinder, the more available volume for filling. Adjusting the length of the piston’s stroke can change this volume. As the stroke is lengthened, the volume of the chamber is increased, and as the stroke is shortened, the volume of the chamber is decreased.

Accuracy is dependent on what percentage of the overall volume of the product cylinder is used. The greater the volume, the more accurate. This series filling machines are accurate to +/- 1% when used in the recommended fill volume ranges for each specific size cylinder. Tabletop type of one nozzle and dual nozzles, floor type of one nozzle and dual nozzles are available for option.
