Automatic hide tanner

The Automatic hide tanner is a machine that can be built in the Invention Guild basement at level 93 Invention. It is a lower level version of the Optimised hide tanner. It automatically converts hides into leather, even while the player is offline. The automatic hide tanner does not incur the normal coin/rune cost for converting hides into leather.

Every hour, on the hour, the automatic hide tanner will process up to 45 items deposited in it, consuming up to 225 machine charge. Building it requires 25 of the power allotment supplied by the generator. It can hold up to 10,000 items over the three input slots.

Once the automatic hide tanner has processed some hides, the resulting leathers may be withdrawn via the machine management interface.
