New application for HiFlux Auto-line
self-cleaning liquid filters (hygienic design)
yields substantial savings
HiFlux Filtration A/S is a leader when it comes to the design of hygienic self-cleaning liquid filters for various food-related applications. New developments in the design of the hygienic Auto-line self-cleaning liquid filters have created new applications for the food industry. A recent success story in the Dutch egg processing industry, which we will discuss below, has a sequel. Other egg processing companies too are now optimizing their production and processes by using the HiFlux Auto-line self-cleaning liquid filters with hygienic design.
Positive results with Auto-line test filter
Charles Scriwanek (country representative manager at HiFlux Filtration A/S): My first contact with the egg processing industry was with Adriaan Goede in Landsmeer at the end of 2016. I had an appointment with Gerwin Roelofs (chief operating officer at Adriaan Goede), who was initially interested in the HiFlux Auto-line for filtering a waste water flow. During the presentation we also discussed the various applications of the Auto-line in the hygienic design for the food industry. This gave him the opportunity to talk about the filtration opportunities immediately after the breaking machine, protein filtration, egg yolk and the entire egg. Soon it was decided to carry out a test with an Auto-line test filter. We have a considerable number of test filters in Denmark, which we are able to use for testing at customers. HiFlux carried out several tests together with Adriaan Goede using different types of filter elements and scraper systems, until we found the right configuration for this new filtration application.
Environmentally friendly saving
Previously there were some issues, such as production interruptions and high maintenance costs on the existing filter system. The follow-up steps in the production process were also negatively influenced because of the contamination present, including high maintenance costs for the centrifuges and the spray dryers. Gerwin Roelofs: My idea was to improve continuity and production capacity. I wanted to eliminate the interim cleaning of the current filters and I also aimed at lowering the high maintenance costs of the centrifuges and spray dryers. Now that we have been using the three Auto-line self-cleaning liquid filters for more than a year, we are able to conclude that we have achieved the targets. An added advantage is that we are making a positive contribution to the environment! We use less water, significantly less conditioned compressed air and also have a reduced loss of expensive product. Its good for the environment and its also an interesting additional saving!
Particularly positive result
Finally, a particularly positive result was achieved together:
In the existing situation, protein was filtered at 800 microns; using the Auto-line, filtration is now being done at 100 microns.
In the existing situation the egg yolk and the whole egg were filtered at 1000 microns; using the Auto-line, filtration is now being done at 500 microns.
No more production interruptions, the Auto-line runs continuously, with 16 hours per day non-stop production.
This means savings on maintenance costs for the centrifuges and the Auto-line ensures that cleaner product goes to the centrifuges.
There are savings on spray dryers, extended service life of spray nozzles, prevention of blockages; the Auto-line ensures that cleaner product goes to the spray dryers.
There is no manual cleaning, as with old filter system; the Auto-line in hygienic design may be CIP cleaned in-line.
There is less use of rinsing water, much less consumption of conditioned compressed air and reduced loss of valuable product.
Success story has a sequel
Thanks to this success, we have now also received project orders from other Dutch and foreign egg processing companies. If you look at the photo above, Adriaan Goede can certainly be proud of the end result. Obviously we will be contacting all other companies in the egg processing industry that have not yet purchased the HiFlux Auto-line, concludes Charles Scriwanek. The Auto-line self-cleaning liquid filters are designed in accordance with the EC 1935/2004 European Directive, they comply with the FDA material approval requirements and the design recommendations of the European Hygienic Equipment Design Group (EHEDG).
