Pedrotti/master drier nozzles

[Rs chunk]

Just been servicing the drier and took out both nozzles a 6 and a 4 now I can’t remember what one was where? Should the larger one be first at the igniter? Thanks

IF i remember correctly the book says the smaller one should fire first but we did it the other way round as it was easier to get the flame correct.

Six is the main one usually, 4 is second flame but the idea is to swap them around and for others to get it running/burning smoothly for whatever air temp your running at.

It’s actually last year I mixed them up and I had it with the 4 as main and 6 secondary it seemed too work okay but was giving drier a look over today and got it in my head the larger one should be first

It would work for lower air temps like that, but the idea is that number 1 jet runs constantly and the second one flicks in and out to maintain the set temp. Too big a nozzle in number two could keep tripping the safety cut out. For beans at lower temps you put the 4 gph nozzle in and turn off the second jet.

Does anybody know a good supplier of nozzles suitable for a master drier?

What way round are your nozzles big first or little?

What are you guys using to lube the agitator chain it’s always dry with the heat? Also how often do ya grease the agitator ring bearing same with it no matter how often I grease it

Never greased ours in 30 years of master ownership

The bigger nozzle should be fitted where the ignition electrodes are, then the smaller nozzle is the one that turns on and off, controlled by the setting on your air temperature gauge.

I asked because I have searched online heating suppliers, but their nozzles are much lower flow rate.

in that case master would be the obvious choice. their service is very good.

Is there no grease nipples on yours? I have 2 up inside and then one that’s piped too the outside of drier beside the one for the middle bearing on main auger

Old one we had to go inside to grease it.

One we have now is all greasable externally but the grease only does bearings not the internal ring gear or any chains on the agitator.
