Oerlikon Leybold Vacuum Offers Leather Drying Technology

Oerlikon Leybold Vacuum now offers a solutions for applications for Leather Vacuum Drying Technology. One of the important operations in the leather-making process is the removal of excess water from leather--drying. Leather acquires its final texture, consistency and flexibility in the drying operations.

Leather Vacuum Drying is key to augmenting the surface properties of leather. It enables modification of the quality of leather, correction of textural faults and inconsistencies, and increases its lifecycle significantly. Vacuum Drying involves leather being placed on a hot plate within an insulated chamber and its water content being removed by creating a vacuum inside the chamber. Vacuum technology is superior simply because moisture evaporates more quickly under vacuum and reduces waste water.
The impact on our environment is a critical factor for businesses these days. The Indian leather industry, which is dependent on exports to a very large extent, is sensitive to this. Moreover, the older technology involving Liquid Ring Pumps requires post water treatment, which adds to the cost as well as reduces efficiency.

Clean and Efficient Technology with Superior Products
Dry Screw Vacuum pumps offer maintenance free performance for long periods as these pumps are capable of handling ingress of water vapor and organic vapors. While offering good suction speed and end pressure, Dry Screw Vacuum Pumps are energy efficient and provide a clean technology, which makes them ideal for the leather industry.

The DRYVAC pumps are a new family of dry compressing vacuum pumps. Depending on the application the pumps are available with various equipment components. The DRYVAC series has been specifically developed for process industry applications. All versions of the DRYVAC family are water cooled, very compact and can simply be mounted to various vacuum systems.
