These systems are primarily used for processing sausage meat using filling machines. However, other highly viscous products from the food industry, such as marzipan, can also be tested for the finest metal residues using these devices. The high-strength product tubes can withstand pressures of up to 55 bar. Connections are made via RD80/HP screw fittings. The entire device is height-adjustable and mobile, allowing it to be connected to all common filling machines. Optionally, devices with linking gears for directly connecting a linking device are available. Matching ejection valves for removing the metal are available.
