How Liquid Sachet Packing Machines Ensure Accurate Filling

In the modern era of packaging, precision and efficiency are paramount. Liquid sachet packing machines play a crucial role in the accurate filling of liquid products into sachets, ensuring product quality, customer satisfaction, and profitability. This article delves into the intricate mechanisms and technologies employed by these machines to achieve precise and consistent filling.

Volumetric Filling

Volumetric Liquid Filling Machines

Volumetric liquid filling machines utilize a piston or pump to measure and dispense a specific volume of liquid. The piston or pump is calibrated to deliver an exact amount of product, ensuring consistent filling regardless of variations in liquid viscosity or density. Volumetric filling is suitable for a wide range of liquids, making it a versatile option for various industries.

Overflow Filling

Overflow Liquid Filling Machines

Overflow liquid filling machines work on the principle of gravity. The machine fills the sachet to the brim, and the excess liquid overflows into a reservoir. The overflow is then recycled back into the filling system, minimizing product waste. Overflow filling is commonly used for filling viscous liquids that do not foam or bubble.

Timing Fillers

Timed Liquid Filling Machines

Timed liquid filling machines dispense liquid for a predetermined amount of time. The flow rate of the liquid is carefully controlled, ensuring that each sachet receives the correct volume. Timed filling is often used for filling liquids that are highly viscous or prone to foaming.

Level Sensors

Liquid Level Sensors

Liquid level sensors play a vital role in ensuring accurate filling. These sensors monitor the liquid level within the sachet during the filling process. If the liquid level exceeds the desired height, the sensor triggers an alarm or shuts off the filling valve, preventing overfilling.

Product Backflow Prevention

Preventing Liquid Backflow

Liquid backflow occurs when liquid flows back into the filling system after the filling cycle is complete. Backflow can result in contamination and product loss. Liquid sachet packing machines employ various mechanisms to prevent backflow, such as non-return valves, vacuum breakers, and sealing devices.

Quality Control Measures

Quality Control in Liquid Sachet Filling

Rigorous quality control measures are essential to ensure the accuracy and reliability of liquid sachet packing machines. These measures include regular calibration of equipment, monitoring of filling parameters, and implementation of statistical process control (SPC) techniques. SPC involves collecting and analyzing data to identify trends, reduce variation, and improve overall process performance.

Liquid sachet packing machines play a vital role in ensuring accurate filling of liquid products. They employ a range of technologies, including volumetric filling, overflow filling, timing fillers, level sensors, and product backflow prevention mechanisms. By adhering to strict quality control measures, these machines deliver precise and consistent filling, contributing to product quality, customer satisfaction, and business profitability.
