    Grain out System

    We are about to jump into a new facility with a 30 Bbl brewhouse. Currently on our 15 Bbl system we are able to pull the mash out into buckets, onto a pallet, then onto the farmers trailer.
    This will undoubtedly be an unachievable task once we make the jump. I'm curious what kind of grain out system people have with a similar sized system? Any ideas, tips, or advice would be greatly appreciated.

    Cheers,

    Cheers,
    You might not want to dump that system too quickly. Years ago, when I was brewing in Colorado, we had a 50bbl Newlands system. The mash tun bottom was about shoulder heights and it had a bottom manway dump. We would dump all the grain into 50gal buckets, palletize them, and wheel 'em out. I think it took about 10-12 buckets but it worked well with the set-up and it was low cost. Aside from that, you could invest in a pneumatic air/tube system that blows the grain out of your brewhouse into a waiting silo or container outside.

    Prost!

    We have a 50 BBL Santa Rosa Stainless System. There is a manway located in the bottom of the vessel. Our mash-rakes have a large crossbar with rubber that can be raised and lowered to efficiently grain out. We pull a hopper underneath the system with a forklift. The system grains out about 90% before someone needs to get in there and spray the rest out. We brew 3 times a day with an average of 3,500 lbs of dry weight per brew ( our largest brew is 5,000 lbs of barley). We own 10 of the 54 cubic feet hoppers. A farmer comes by everyday. Use McMaster-Carr. It is under Steel Easy-Empty Hoppers. They have a variety of hoppers. Totally worth it.

    "This will undoubtedly be an unachievable task once we make the jump."

    Why is that? I worked at a 50bbl facility that had a manual grain-out. And this was in the Southeast, where it was really hot and humid during the summer. Very good exercise, even if a bit strenuous. We loaded a forklift dumper-hopper by shovel, and this hopper was taken by a local farmer daily. It was perfectly adequate albeit low-tech and low-capital.

    Spent Grain Conveyor

    We installed a spent grain conveyor like the one below.

    It was inexpensive and very effective. A hopper sits below the mash tun manway. As grain drops it gets conveyed through the wall outside and into the farmers trailer. We have saved a ton of time and effort.

    Cheers,

    We grain out from our 30 bbl system by hand 3 to 4 days a week, into 44 gallon cans on a pallet. Average dry weight is around 2100#.
    We have a paddle that helps a little, but no rakes, side manway, and most of the work is old fashioned shovel manipulation.
    You'll be fine.

    Is it difficult to keep clean?

    No you just run it while taking a hose to it. Pretty easy.

    I run a 30 bbl Spec Mech with a bottom manway, with rake that has a drop down plow. We fill two plastic forklift able totes per batch. We had to cut off a lower spacer bar between two of the mash tun legs to be able to slide them in. A farmer brings them, he has about 8 that he rotates in and out of the brewery. He picks them up the day of the brew, it works great, we are happy to be rid of the spent grain and he blends it in with feed.

    Grain out "Wet"

    Anyone on this post, have experience and/or advice in efficiently drying the spent grains (roughly 75% moisture to 10% or less) for Storage, Transport and/or Disposal. Got to love the wonderful smell of spent grain “fermenting or going moldy” until removal.
    We are talking about creating a tumble drying unit and using the exhausted heat and a tornado heater as a source to vent the heated air onto the grains.

    Thank you all for your time in advance,
    /s Chris “TuffToad”

    Lots of information on the board under "drying spent grains". Check it out using the search function. Been hit pretty well there.
