HOW IS A QUALITY MEMBRANE MADE?

For the filtration of wine, beer, juices, soft drinks and beverages, it is essential to use first-class, high-performance filtering elements. 

The AEB range includes final membranes and prefiltration elements aimed at obtaining the ideal water for your production processes, both in cleaning and as an ingredient of the finished product.

Filtration is a complex process: its quality depends on numerous variables which are linked to the product being filtered. What are the features which make a prefiltration element capable of fulfilling its purpose correctly, guaranteeing the microbial stability of the beverages?

To understand this aspect, we will give you a detailed look at the production process of our filtering elements: a journey into the world of AEB to enable you to recognise the features behind a top-quality filter cartridge.

An important factor is sustainability. In light of our Group’s commitment to environmentally-friendly development, AEB filtering products are made of recyclable components.

All the components of the cartridge are assembled in-house to guarantee the highest quality and complete control over the production process. This is combined with the complete traceability of the 10-inch modules which bear the code, batch and micrometre measurement.

So, let’s take a closer look and examine the elements which make up the cartridge:

• The AEB tip: it is solid which prevents the accumulation of water or wine and eliminates the risk of microbial problems due to residue.
• The AEB ring: it is not fused inside the adaptor. This is an important aspect which prevents the problem of by-pass caused by the different expansion properties of plastic and steel. For this application, AEB, together with our Group, has developed equipment borrowed from precision mechanics which eliminates any risk of micro-cracks during insertion. Furthermore, in keeping with our commitment to sustainable development, the conformation of the AEB ring is ideal for the environment because it allows the materials to be separated and recycled.
• The protective cage: AEB has developed a special design for the protective cage to ensure resistance to sterilisation cycles and high hourly flow rates. The most significant innovation lies in the use of offset intervals between the various openings, which ensure elasticity during sterilisation and the cooling of the cartridge, thus preventing it from breaking.
• The inner core: the central inner core support is reinforced, and thanks to its size, adds stability and resistance to the filter element.

For a perfect join of the end elements, AEB uses an infrared system, which avoids direct contact between the sealing point and the heat source, thus ensuring perfect alignment. The 10-inch module is then inserted inside the operating machine where two steel plates are heated by induction which, in turn, heat the ends of the module and two end elements to be joined. After this, the steel plates retract and the end elements are brought together and sealed.

Thanks to all these precautions, AEB ensures an impeccable fusion of the three elements - membrane, cap and cage - so the resulting cartridge is perfect from all aspects.
