Pigging / Scraping Systems - Type A

The scraper is launched behind the product at the end of production to create a “barrier” with the pusher fluid and avoid mixing.

After the clean in place operation is completed, the scraper module drains the pipeline in preparation for the next production cycle before returning to its home position inside the launcher.

The scraper moves forwards and backwards between the launcher and the receiver within the same single pipe.

Pigging / Scraping Systems - Type B

The scraper is launched between each product interface and returns to the launcher via a secondary pipeline. The scraper always moves in the same direction in a closed loop pipeline. The scraper can be used multiple times without stopping production.

Particularly suitable for processes such as fruit injection which do not require cleaning between product changeover.

Process Diagram for Stirred Yogurt Production

Fruit yogurt production can combine return scraping (type A) on yogurt pipeline and closed loop scraping (type B) on fruit lines.

At each flavor changeover on each injection line, scraper (type B) is launched without stopping production.

At the end of production, maximum amount of both yogurt and fruit is recovered thanks to the combination of both types of scraping systems
