Application rangesProduct push-out
Product recovery systems are used for the ejection of viscous / flowing products from pipelines without mixing with any other media. This is especially required for high quality products in the food and beverages industries, as well as, pharmaceutical and personal and health care industries.
In addition to pushing out of products from the pipelines, product recovery systems are also used for gentle filling of pipelines with sensitive and foaming products. Even vertical pipelines can be easily filled by letting the product push the pig downwards in the pipe.
Types of product recovery systems
The pigging process can be implemented with different degrees of automation. That is why the portfolio of GEA Tuchenhagen offers three different product recovery systems:
1. Automatic product recovery systems
Due to the complete automation of the process, the pig can push out and be cleaned without manual action. The entire process takes place solely in the pipeline.Special features
2. Semi-automatic product recovery systems In contrast to the automatic product recovery systems, with the semi-automatic product recovery systems the pig is inserted and removed manually. Pushing out of product and returning of the pig then takes place automatically.
3. Manual product recovery systems In the manual product recovery system, the pig is manually inserted into the pipeline and at the end removed manually. The pig runs in only one direction.
Design of a product recovery systemA VARICOVER® product recovery system usually comprises of a pig cleaning station, a pig catching station with propellant medium valves, and a pig. The pig is placed in the pig cleaning station during production and cleaning. In the pig catching station, the pig is stopped mechanically after successful product push-out and the propellant medium valves are used for propellant medium supply (air/water). The pig components can be installed either in new systems or integrated into already present process systems.
