Very efficient super smelter for Minecraft Java edition

Have you made a super smelter that A) has the input chests on a different level than the output chests, B) has no on/off feature for the minecarts, making the super-smelter extremely noisy, and/or C) is slow to smelt your items? Well, look no further. This super smelter will automatically take, cook, and deliver your items to you for easy and efficient smelting! It includes a lever which can turn the minecarts on and off at will, so you can have a quiet house when it's not in use. I make my own music: https://www.youtube.com/channel/UCff3ywNSyUVYYZEWK_DRRLA
