Falling Film Evaporators

Cleaning of falling film evaporators

Falling film evaporators are used in the food industry and in particular at factories active in the dairy industry. These installations have a relatively large number of tubes that will become fouled over time with the product that flows through them. Over time, especially with dairy products, this deposit can form into a very hard substance, sometimes resulting in blocked tubes.

In addition to the regular (CIP) cleaning procedure, it may be wise to periodically apply a mechanical cleaning with brushes and, if necessary, heavy-duty scrapers. The friction that is created will ensure that deposits on the tube walls are quickly released and flushed out of the tubes. It is also possible to open completely blocked tubes with specialist tools in the event of an emergency.

Applications and usage

De reiniging apparatuur voor falling film indampers kan voor vrijwel elke installatie worden ingezet. Afhankelijk van de pijpdiameter, lengte, en hoeveelheid pijpen kan er voor een specifieke opzet gekozen worden. In principe bestaat een reinigingspakket altijd uit:

The cleaning equipment for falling film evaporators can be used for almost any installation. Depending on the tube diameter, length and quantity of tubes, a set-up can be customized. In principle, a cleaning package always consists of:

1. Tube cleaning system, such as the AWT-100X
2. Flexible shaft
3. Nylon abrasive brushes for regular cleaning and maintenance
4. Scrapers for hard deposits and blocked tubes

Ondanks een reguliere reiniging en goede planning, kunnen er nog steeds problemen ontstaan waardoor de pijpen van indampers vervuild of verstopt raken. In dat geval biedt het apparatuur van Goodway Benelux een goede oplossing. Veel grote fabrieken maken al gebruik van dit apparatuur voor hun preventieve en/of reactieve reinigingswerkzaamheden. Enkele voorbeelden zijn:

Despite regular cleaning and good planning, problems can still arise that cause the tubes of evaporators to become fouled or clogged. In that case, equipment from Goodway Benelux offers a good solution. Many large factories already use this equipment for their preventive and/or reactive cleaning activities. Some examples are:

• Nestlé, Friesland Campina, Bel Group, Beneo, and more.
• The above companies use the Goodway AWT-100X system, read about their experiences here.
