Pneumatic transport system

Conveying and handling are essential steps in every production process. Slow Flow Conveying, based on the principle of vacuum transport and/or blow transport, suits the transport of materials that are fragile and sensitive to wear and tear.

Slow Flow Conveying offers a balance between low energy consumption and production versatility. It works with low air speeds, high loading factors and reduced air consumption, making it suitable for transporting ingredients hygienically, carefully and efficiently. The system is based on the principle of vacuum transport and/or blow transport. A controlled flow of air or gas is used to transport powders, granules, granulates etc., making it possible to transport a wide range of products from one or more inlet points to a single compact receiver unit. The opposite is also possible, i.e. products can be transported from a single location to several receiving points.

As the ratio between the amount of air or gas used for transport and the transport load is quite moderate, the resulting transport speeds and the friction that arises between the particles during transportation are relatively low. This makes Slow Flow Conveying suitable for transporting materials that are fragile and sensitive to wear and tear, such as milk powders, sand, chalk, coffee and instant powders as well as prepared, extruded and lecithinated products. Sticky products such as cereals and cocoa and hygroscopic products such as sugar are less prone to caking and sticking when transported this way.

Slow Flow Conveying works with relatively low air speeds and relatively high loading factors. As the system requires only a moderate supply of air/gas for transport purposes, small-diameter pipes, a highly compact receiver system and small filters can be used. The compact nature of these components makes it possible to clean the system much more quickly and easily. The receiver unit incorporates easy-to-clean functionality and the filters can be removed via a special guide system. The pipes are also easily accessible and removable, making it possible to rapidly inspect and clean the departure and receiving locations. Any slide gates or pressure vessels used are also compact and can be cleaned easily and quickly. All these intelligent facilities make the conveying system easy to clean quickly and effectively. The system can be equipped with an automatic air-based cleaning system. CIP cleaning options based on water and/or cleaning agents (soaking and/or flushing) are also available.
