Phil's 2" Perforated Plates on Boka
Posted: Sun Feb 10, 2013 3:08 pm
I've been running my 2" boka slowly for neutral and flat out for whisky/bourbon etc... The mesh packing works great however I wanted to try something new and build something interesting. So with inspiration from this forum I'm trying to make a set of 4 perforated plates that I can slide into the bottom of the column interchangeable with the mesh packing. The goal is good UJSM, whisky and hopefully rum.
Don't have much money to splash on this atm so i've utilised what I have rather than what would be best, for example the diameter of the down-comers is not really in proportion to the column. I would love to get a 3" or 4" build going with sight glasses etc.. but that will have to be down the track. The coil condensor above the boka plates isn't really the norm for this type of setup, I'm sure it will work but how well?? Here is some progress so far:
Cut and file the disks as close as possible then jam them in the press and round off with a file
3/4" pipe almost round with 18 x 1.5mm holes at roughly 8% of surface area
1/2" down-comer with 6.5mm hole in the top, did it like this to save a little space
One question. I'm thinking of spacing the plates about 15cm apart and the column is 135cm from boiler lid to take off plate. Would it be best to sit the plates in the middle of the column or towards either top or bottom of the column?
I have some 4th gen UJSM fermenting at the moment and I hope to run this one weekend before the end of the month.
I have no idea if this is going to work and haven't seen much info about 2" plates or what they are capable of, ideas, criticism and pointers most welcome!
