Wetback Drum
In addition to the preservation with the salting process of raw hides, another widely used system, but in the case of semi-processed hides, is what is called WET-BLUE.
The WET-BLUE leathers, in fact, are tanned leathers and then pressed dehydrated, able to keep stable even for medium long periods.
The leathers, in this condition however, cannot be processed, must first be rehydrated.
The traditional system used to rehydrate the leathers, by a process commonly called wet back, takes place through the use of a wooden drum, where first the leathers are loaded into wet-blue, then water is added and the rotation process starts, once finished, the drum is emptied by unloading all the skins and all the water on tanks or on the ground.
The continuous Wet back Drum, unlike the more traditional wood drum has countless advantages.
How It Works
The leathers are loaded with a conveyor belt or with a handler on the loading hopper, and slide inside the rotating basket.
This long basket, rotates with a part immersed in water, inside it has a series of steel vanes, which continue to move and rotate the skins in a continuous cycle of immersion and emersion from the water, this mechanical action facilitates and accelerates the rehydration process.
At the end of the hydration process, reversing the direction of rotation, the leathers, through the appropriate positioning of the vanes inside the basket are carried out from the opposite side to the loading mouth and unloaded on the belts.
