DESCRIPTION
The SABF-4 is a semi-automatic overflow bottle filling machine designed for a wide range of still liquid food and non-food products. It is well suited to products where a consistent filling level is important. The overflow filling system maintains the required fill level across bottles with different internal volumes, while the machine handles PET, HDPE and glass bottles from 250 to 3,000 ml without changeover parts or tools.
The overflow filling technology also makes the SABF-4 suitable for liquid products that tend to foam during filling. The filling nozzle fits closely into the bottle neck during filling, helping contain the foam and direct it back through the overflow system rather than allowing it to escape from the bottle. This allows foaming products to fill quickly while maintaining a clean filling process and consistent product level.
With four filling heads and two alternating filling sections, the SABF-4 reduces manual handling compared with conventional manual filling and provides a practical solution for small-scale production.
OPERATING PRINCIPLE
The SABF-4 uses four filling heads arranged in two alternating sections. The operator places two empty bottles on the filling platform and activates the pneumatic switch. The platform raises the bottles and presses them firmly against the filling nozzles to form a close seal around the bottle necks.
The product then flows into the bottles until it reaches the set filling level. A mechanical overflow valve stops the filling when the required level is reached. Any excess product or foam above the filling level is discharged through the overflow outlet tube rather than escaping from the bottle.
Once filling is complete, the platform lowers the bottles. The operator removes the filled bottles and replaces them with empty bottles while the other pair is being filled. The two sections operate alternately, allowing continuous manual loading and unloading during the filling cycle.
PRODUCT APPLICATIONS
The SABF-4 is designed for free-flowing liquid products that can be transferred through the standard hygienic centrifugal product feed pump. The overflow filling system is particularly suitable for products where a consistent filling level is important and can also handle liquids that tend to foam during filling.
Typical applications include water, milk, juice, edible oils and other free-flowing liquid food and non-food products. Product viscosity, foaming behaviour and compatibility with the product feed system should be confirmed during machine specification.
