hydrasieve

Recommended Posts

morning all , i was wondering if anyone has had any experience with a hydra sieve static screen . we have a chance to pick one up and any info would be great . our mash bill is 100 % barley and a 3 water infusion mash , mash tun has lauter pipes  for first and second water . were hoping to use hydra sieve for third water , this would allow us to pump third water and spent  grain out of the mash tun as a slurry  instead of having to shovel it out .  it seems like this would solve the brain twizzler of shovelling spent grain , makes sense in my mind but there lots of things bouncing around in my mind that only make sense in there .

Hey Tim, this sounds really interesting - do you have any idea as to the cost?

were not really settled on a price yet but if im sure it will work i plan on going to look at it closer , it comes out of a shut down brewery so im hoping it will work with our mash bill .

here a update on the hydrasieve static screen . we decided to go for it and give it a try .

we have some modifications in mind they will all depend on how well it works as is . if it works as is then we wont mess with it .

the first modification will be the clear water discharge, we will be adding triclamp fittings instead of screw in pipe thread . next will be to add a 2 inch pipe with holes or T's in it to the top of the weir . from the factory it is designed to pump into a small holding tank at top then over flow the weir and down the screen . this in my mind would end up with solids build up in bottom of holding tank that would then need to be cleaned . so i think pumping to the top of the weir will keep solids out of the holding tank , one less thing to clean out . next modification if need be will be to change the stand it sits on to one that is hinged giving us the ability to tilt it back decreasing the angle and slowing down the rate  the grain falls . slower it falls the more time it has to drop the water thru screen . now if the grain is still to wet we have the ability to  tilt it way back add rubber spring blocks to the mounting frame and then add vibrating motor , then like a vibrasieve rely on vibration and a slight angle to move solids down the screen instead of just gravity . 

now if it still doesn't do the job we want then im out of bright ideas , lets just hope it will work as is with no modifications of the rate the solids come down .  

as far as setting it up to work with the mash tun here the plan .... when the third water is ready to be discharged from the mash tun  the slury  of third water and spent grain is pumped out of the mash tun thru the hydrasieve and returned to the mash tun as it circulates the third water can be sprayed around to wash the solids out and give the mash tun a quick rinse . eventually all the solids should be out and third water can remain in the mash tun as tomorrows first water and temp maintained over night .  now because were loosing water volume to hydrating the next batch of grist  we can rinse the hydrasieve with hot pressure water to clean it.  add that water to the third water volume to bring  to the level we need for next mash . at a rate of 30 gallons per 100 water temp should be stable enough to be easily held over till morning when it will be  circulated from the mash tun thru the grist hydrator  with new grist and away we go again . 

now im sure there will be some changes in the process as we go along as it always is when adding a new piece of kit so if anyone can spot a flaw in the pre plan please share . good advice always trumps trial and error .

had a great discovery while acid bathing the hydraseive ......three wing nuts and tada the screen can be lifted up for easy cleaning of screen and collection area . im super impressed with the quality of the construction of this unit .
