The PIG system is ideal for the recovery of any product remaining in a pipeline at the end of the transfer process. As this product can be of a high value the PIG system recovers the product removing it from the pipelines and preparing the pipeline for a CIP process. Another benefit is the reduction of the fluid sent to the sewage treatment plant that results in saving energy and water.
The main application of the system is viscous media. Among the products treated there are chocolates, marmelades, confectionary creams in the food-processing industry, or gels, creames and other body care products of high value in the cosmetic industry.
Operating principle
The SILPIG system consists of a sending station, a receiving station, the PIG, two position detectors, four A480 butterfly valves, and two INNOVA K valves.
The process begins by placing the PIG in the launch position. It is propelled toward the receiving station by a driving fluid, usually compressed air. As it moves, the PIG pushes the product inside the pipeline for recovery. Once it reaches the receiving station, the entire system can be cleaned through CIP, with the added advantage that the PIG is also cleaned. After this phase, the PIG is returned to the launch station, and the system is ready for the next production cycle.
