  • Lenticular or Plate and Frame

    We are looking into getting a filter for our Brewpub and I am trying to figure out the best option to pitch to the owners on what to get. Currently we are fining everything, but we because we have started a small packaging line I am finding that the fining process is taking way too long for me to keep up with the demand.

    We are a 17hl brewhouse brewing about 1800hl/year, usually brewing and transferring twice a week.

    I want to predominantly filter my Kolsch and Red ale, as well as some of the rotating taps to try and get them ready faster, so I will probably need something around 1-2.5 microns.

    Space is also at a premium at my place, so something that takes up less of a foot print, or it mobile would be best.

    I am thinking Lenticular or plate and frame would do the trick for this, but I need some advice on which one would be a better suit to my brewhouse. I know plate and frames can be more mobile and cheaper to run, but lenticular has much lower losses and DO pick up and the cartridges can last a lot longer than P&F.

    Any advice is much appreciated.

    Cheers,

    I have no experience with Plate and Frame. Lenticulars have a very small footprint. Both do take a lot of flushing. I have had a very good experience with the life of the cartridges on our Lenticular, we are polishing with it though so the load is light. Our primary filter is a Velo.

      Hi!
      When I try to determine filtration options for the brewer, it normally comes down to what is most important for them.

      If material pricing is the most important, then DE is probably your best bet. While the equipment can be expensive, and a skilled operator is required, the actual cost of DE is low. There can be other issues tho, such as bypass and O2 pickup, but if those are not important, DE is their best bet.

      Sheet manufacturers (Pall being one of them), use raw DE and make it into Sheets. Sheets have the benefit of being easier to use than raw DE, and are flexible and can take decent solid loading (since they are disposable). They are more expensive on material basis than raw DE, but cheaper than Lenticular. The downsides can be product loss due to dripping or when the filter press is unloaded, as well as O2 pickup and being exposed to the environment. Filter presses are larger than Lenticulars, but can be stored away since they will be cleaned and emptied after usage.

      Lenticular manufacturers (Pall being one of them with SUPRAdisc II and SUPRApak) use filter sheets and enclose it to make it modular. This has the benefit of making it reusable and enclosed, so there is very little O2 pickup and the housing can be completely emptied of product before storage, so there is little losses. It is more expensive than sheets on a material basis, but the ROI comes in the form of better quality beer, as well as elimination of losses traditionally associated with filtration. Whether the increased cost is offset by the increase in quality is typically why we have a sales specialist go through it with brewers to make sure that they feel comfortable with their decision.

      Sorry that this was a long post, but I figure that for every question asked, there are 10 brewers that remain silent, so I wanted to give as much info as possible (within reason).

      If you still have questions, please feel free to contact me at Milton.Leland@Pall.com.

      Thanks!
