we regularly run 5-10lbs in a day when were going,, r trim sux soo it turns out black at the moment (diff post) but the process is the same
we start around noon ,, tube is 2" x 18" stainless,,, holds 6.5oz wen packed (roughly 3 tubes per lb),,,, 4-6cans of butane per tube depending how long to blow clear,,,, usually takes about 30 mins per tube from pack to spray to unpack n repeat,,,, the most weve done was 15lbs in one day and it took us fromm 10am til 9pm before we finally had everything evapd enuf for the vac chamber
(my tube cost me 40$ to build myself and i love it but if your doing alot of runs and dont have a stand uu better have a buddy to take turns with cause your arms will turn to jello)
