Sesotec LIQUISCAN Metal Detectors
Sesotec LIQUISCAN metal detection systems are designed for the reliable detection and separation of metallic contaminants from liquid, viscous and pasty food products directly in pipelines. The systems detect magnetic and non-magnetic metals, including iron, steel, stainless steel and non-ferrous metals such as aluminium, copper and brass.
LIQUISCAN systems can be integrated into existing production lines and are compatible with standard vacuum fillers, pumps, clipping machines and sausage filling systems. Their hygienic stainless-steel construction, high detection sensitivity and automatic reject options make them suitable for demanding food-production environments and IFS/HACCP quality-control concepts.

THiNK Artificial Intelligence
For products with particularly strong product effects, the LIQUISCAN VF IC can be equipped with Sesotec THiNK AI software. THiNK uses multidimensional AI algorithms to model the product signal more precisely, allowing the detection threshold to follow the product effect more closely. This can increase detection sensitivity while reducing false rejects.
Potential benefits include improved protection against product recalls, reduced food waste, higher production efficiency and more reliable detection in difficult products.

Easy Integration into Existing Food Production Lines
One of the main advantages of the LIQUISCAN family is its ability to integrate directly into existing processing equipment.
For filler applications, LIQUISCAN VF can be connected to production processes such as clipping, calibration, twisting and hanging. Different data interfaces also enable communication with vacuum fillers, helping minimize the amount of product rejected when metal is detected.
Reject Systems for Different Product Consistencies
LIQUISCAN systems can be configured with different separation valves according to the consistency and composition of the inspected product. This allows detected contaminants to be automatically removed from the product stream.
|
Reject system |
Suitable applications |
|---|---|
|
Piston valve |
Pulpy and pasty products without large pieces; not suitable for aqueous products |
|
Ball valve |
Liquid or pasty products, including products containing larger pieces such as muscle meat |
|
Arc valve |
Soups and very watery products |
Hygienic Design and Food Safety
LIQUISCAN systems are designed for food-production environments with stringent hygiene requirements. The systems use stainless steel and food-contact-approved plastics, while the hygienic casing and inclined surfaces support cleaning and water drainage. Depending on the configuration, high IP protection and optional display protection support intensive wet cleaning.
Sesotec positions LIQUISCAN around six priorities: conformity and accuracy, safety for people and products, simple operation, hygiene, efficiency and reliable service.
Optional Connectivity and Production Monitoring
Depending on the model and configuration, LIQUISCAN systems can be integrated into plant networks using options including OPC UA, PROFIBUS, PROFINET, MQTT and REST API. Sesotec also offers INTERLINK communication and Insight.NET / Insight.WEB for visualization, logging, remote access and diagnostics.
