Too much? I’d have to measure it, but more than I like as I’m not recirculating it.
So I measured the flow rates. Still was not running but having scribed a mark in the gate valve spindle at the 12 O’clock position when fully off, I can replicate the settings. Due to the backlash in the cheap valves, you need to make fine adjustments in the OFF direction. That is, turn it ON a quarter turn further than desired, then carefully close the valve to the position required.
Full reflux uses 4.49L/min or 269L/hr
Partial reflux at spirit run settings was around 0.3L/min or 18L/hr
Using less water during full reflux would be desirable, but I’m wondering just how sensitive an extremely efficient RC is to adjustments? I feel mine is right on the limit of acceptable fine control with the gate valve.
