NeroRapido

The current tanning market is increasingly attentive to the environment not only in the leather processing cycle but also in the energy consumption of the tannery. The new trend is to treat leathers with low environmental impact in tanning / retanning process. FOC leathers, in the drying stages, can reach very low temperatures, which is why we have modified the vacuum circuit. 

To ensure maximum drying results, we have designed a vacuum unit capable of bringing the leather from atmospheric pressure to a very low Mbar level in 6/7 seconds, thus the leather never reaches the temperature set on the table due to the speed of process.

The low pressure is constant throughout the evaporation process time, so we guarantee a temperature between 20-25 ° for the entire drying cycle.

With the new NeroRapido vacuum dryer we are able to dry the leather in a very short time, bringing it to a humidity between 22-30%, without any non-uniformity. Thanks to this revolution, not only in the system but also in the working method, we are able to optimize the consumption of the entire drying cycle.

A vacuum of this type to produces 100 hides / hour guarantees an average consumption of about 27-30 Kw / h.

Thanks to the extremely low temperatures we are able to dry the leathers without:

– reduction of area and thickness;

– migration of chemicals.

The leather is soft, round and super uniform.
