After recently centralizing item storage and sorting at my base, I found myself with some chests approaching overflowing. Especially some mixed farms (like the generic mob farm) produce more of some items than I know what to do with - like arrows. And as I don't want my sorting system to jam up (or discard whatever passes unsorted... e.g. in case another farm's collection system picks up my trident I'd accidentally dropped on a hopper) I need to periodically empty the overflowing chests, and e.g. discard a double chest of arrows.
So I built a trashcan. I'd move the arrows to a double chest in the floor, and it would transfer them through a hopper to a dropper into lava. And as I'd work around the item storage area I'd suffer clicking of the dropper for another 12 minutes as it kills 1728 arrows, one by one.
I managed to about halve the time by applying a faster clock and feeding the dropper through two hoppers from the same double chest at once, but it's still six minutes of incessant clicking (at double rate).
Can you suggest a trashcan system that can either kill a double chest of items relatively silently (may be slower) or do it so fast I won't be driven mad by the clicking? (and no, just dropping them on the ground to despawn isn't the right solution because I need to drop every stack of items separately, while transferring the full inventory to a chest just requires me to doubleclick a stack of arrows while holding another stack of arrows.)
Moderate compactness is a plus. Like, I don't mind dedicating an 8x8x8 chamber to the trash system, but I'd prefer the solution not to be a chain of hoppers so long it carries the items outside my hearing range. (also, while I began seriously considering throwing full shulker boxes into lava, I'm not quite that rich yet...)
