  • Anybody using Slot Drains?

    We are building a new production facility and looking at floor drain options. We are considering slot drains from http://www.slotdrainsystems.com/ does anybody have any experience with these drains? I am especially interested in feedback regarding their ability to drink yeast as at this point we dump yeast down our drains while adding 190 degree water.

    Any help would be appreciated,

    I'm also interested in hearing if anyone would recommend another product other than slotdrainsystems.com. I've got a quote from them but am wanting to get a few more quotes before I lock one in.
    Max I've been working in a brewery with a slot drain and if you dump a lot of yeast it backs up a bit and you need or slow or stop draining whatever you're draining. This will happen even if you put the drain hose directly in the end catch basin with a screen and 4" outlet. So I think most drains will struggle to handle a large dump of yeast, even the non slot trench styles. For that reason and the city of Vancouver's fermentation bylaw, we now sidestream all yeast before the drain.

      Thank you for your interest. Here's some information on yeast disposal and Slot Drain® that might help.

      Slot Drain® is made of stainless steel and it can handle extreme temperatures. Yeast can increase BOD and TSS and there are different regulations and bylaws.

      Montana Pollutant Discharge Elimination System Permit Fact Sheet
      City of Vancouver Sewer and Water course By-law

      Some ideas on yeast disposal:
      - Side stream (collecting high strength, concentrated wastes at the source and setting it aside for disposal) yeast
      - Pass the slurry through a filter press or centrifuge to recover residual beer that may be reuse in the process. The remains maybe disposed separately or sold as animal feed additives.
      - Use spent yeast as a byproduct, reuse it in the next fermentation batch or recycle it as animal feed or fertilizer

      The reasons why Slot Drain® is suitable for breweries:
      - Corrosion resistant at high temperatures
      - Forklift and pallet jack friendly, NO GRATES to break or rust
      - Easy to clean and sanitize. Watch video
