ADF/BDF Series Liquid Filling Scales
The Yazhen electronic filling scales, specifically the ADF and BDF series liquid filling scales, are equipment designed for the automatic weighing and packaging of liquid materials in industries such as chemical processing, grain handling, and pesticide production. These liquid filling scales employ an electronic weight-detection method for accurate measurement, which helps minimize material spillage and prevents contamination of the surrounding environment by the materials themselves. As a result, they provide effective labor protection for operators. Moreover, the system is capable of operating reliably in humid, hazardous, or other adverse environmental conditions.

Basic filling methods
1. Atmospheric Pressure Method (Gravity Method)
Under atmospheric pressure, the liquid material flows into the packaging container by gravity. This method can be used to fill most freely flowing, non-carbonated liquids, such as baijiu, fruit wine, milk, soy sauce, and vinegar.
2. Isobaric method (pressure-gravity filling method)
Under conditions of pressure higher than atmospheric pressure, the packaging container is first inflated to equalize the internal gas pressure with that in the liquid storage tank, and then the liquid being filled flows into the packaging container solely by its own weight.
3. Differential Pressure Vacuum Method
Inside the storage tank, the pressure is atmospheric; only the packaging container is evacuated to create a vacuum. The liquid material flows into the container to be filled due to the pressure difference between the storage tank and the container being filled.
4. Pressure Method
This method uses mechanical or pneumatic pressure to force the target material into a packaging container. It is primarily used for filling highly viscous, thick materials such as ketchup, minced meat, toothpaste, and balm. Occasionally, it can also be applied to the filling of soft drinks like carbonated beverages. In such cases, the carbonation pressure within the beverage itself is utilized directly to fill unpressurized bottles, thereby increasing the filling speed. Although the foam generated tends to dissipate relatively easily since the carbonated beverage contains no colloids, this does have some impact on filling quality, though not a significant one.

Automated classification of filling processes
1. Hand-filled
The entire filling process is manually controlled. Currently, this method is still relatively common in some small and medium-sized factories, and it’s mostly used for filling non-carbonated liquid products.
2. Semi-automatic filling machine
During filling, bottle loading and unloading are performed manually, but the filling process itself is automated. This type of filling is typically used for liquids containing gas.
3. Automated filling machines of this type can be categorized into single-machine automatic units and integrated automatic units. Integrated automatic units can perform a series of operations continuously, including bottle washing, filling, capping, labeling, and boxing. Mechanical transmission-based control is the most common approach used in automated filling systems.
