Looking for suggestions on separating grain after mashing

58 posts in this topic

I recently borrowed my Son's Hydropress (he juices water mellons for beer) to try to separate more liquid from my rye mash.

A lot of work for nil gain.

In the centre of the press there is a water filled bladder. Hook a hose on and fill to 3 bar(approx. 45 psi)

It started pressing well but slowed to a stop. When I opened it up there was a nice solid 3/4 inch layer against the outside filter cloth but the rest of the mash was as wet as when I put it in. The mash had been compressed into an impervious layer.

(sorry about the sideways orientation)

Ideal I think is something more along the lines of a decanter centrifuge.  I went down this path before, as the prices have come down dramatically with them being manufactured in the east.

When you scroll through Alibaba, the keyword you want to search for is "pig feces".

Can anyone point me to a place (preferably online) that would sell large sheets of this type (or something similar) of plastic mesh screen material?
I have searched the internet and just cant seem to find anyone selling this.  I am hoping that is because I dont know the right word/product to search for.

My though is getting something like this hopper:

and then lining the inside with an finer mesh material.  Pump out of the still into hopper, allow to drain/stain over night...

We are currently mashing rye flour and fermenting/distilling on the grain...

Here is a link to what we use for de-watering our mash.  With a 1500 lbs grain bill it de-waters the mash in under 15 minutes.  We build a PVC manifold that we clamp to the top part of the hopper that spreads the mash out over the filter medium as it runs down the incline.  We build another PVC drain pipe up that hooks to both drains and extends over to our floor drains.  I have a video somewhere that I'll try to find.  We tank the bin out with the fork truck and dump into a 270 gallon tote that has the top cut off.  Farmer Brad picks up a few totes every Monday.  I'm getting ready to buy a second one as our grain bills will go up to 3000 lbs per once we start using the new column still.

I couldn't find the video but here are some pictures of our de-watering setup.  We used this to de-water over 125 tons of grain last year.

thus may have nothing to do with nothing but ill mention it anyway lol. we got our hands on tubes from a old aeration grain bin . these tubes are 4 feet long and about 2 feet in diameter like size of a culvert but made of heavy screen . the science is they lay on the bottom of the bin floor  one attached to the next till u reach the other side of the bin , the bin is filled with wet grain and air is forced thru the tubes and the grain is dried

.anyway they are very strong but also very fine holes so my plan is to use them to separate grain from the wash . set on a angle with a collection tub under it to catch liquid  , as i pump mash into the elevated end  and turn it continually the mash will roll in the giant tube, liquid  comes out thru the screen and the grain eventually rolls out the end . im not sure how many of these tubes i will need but im thinking by adjusting the rotation speed and the angle of the tube i    can find a sweet spot and a 4 foot section will do (i have ten of them but i sure hope i dont need 40 feet of rolling tube to make it work ). the steeper the angle the faster the grain will roll to end of tube the lesser the angle the longer it will roll in tube before reaching the end  this should make it a continual operation and more tubes could be added if volume needed to be increased .

 so does this sound like it will work , i should add the object of the game is to only extract to a moist grain level , so it can be fed out to neighbours. pigs ,

I think you shared your video with me in the past.  What type of grind are you using on your grain?

I have some very similar marerial i scrounged from a local paper mill. I think it is used to de-water pulp in a belt press. Try searching "belt press" parts
