Examine Automatically ensures tanners are never found.

The Optimised hide tanner is a machine that can be built in the Invention Guild basement at level 111 Invention. It is an upgraded version of the Automatic hide tanner. It automatically converts hides into leather, even while the player is offline. The optimised hide tanner does not incur the normal coin/rune cost for converting hides into leather.

Every hour, on the hour, the optimised hide tanner will process up to 140 items deposited in it, consuming up to 840 machine charge. Building it requires 50 of the power allotment supplied by the generator. It can hold up to 30,000 items over the three input slots.

Once the optimised hide tanner has processed some hides, the resulting leathers may be withdrawn via the machine management interface.

The optimised hide tanner processes 140 items per hour at a cost of 840 machine charge. Thus, each item costs 6 machine charge to process - an equivalent of 241.4 coins per item.

The optimised hide tanner processes 3360 items per day at a cost of 20,160 machine charge (approximately 6.7 divine charges). When completely filled, it will take 8 days and 23 hours to process the 30,000 input items, using 180,600 machine charges (approximately 60.2 divine charges).
