Sustainability: Comas drives for a responsible future

Comas ambition to consistently using its extensive expertise to create more sustainable innovations for preserving the ecosystem is stronger than ever.
Focused to transform the technological portfolio to a more responsible level, Comas is setting up several strategic optimizations to minimize the equipment footprint and reduce external emissions during the production flows.

Starting from the most energy consuming machines, like dryers, Comas' R&D department has recently developed a system for recovering the steam contained in the processed gas expelled from the tower dryer, representing the most advanced air-drying technology for cut tobacco and stems.

This machine, a closed re-circulation loop air dryer, provides accelerated expansion and drying of the products, by using superheated steam in a low oxygen environment. 

The innovative sustainable system utilizes heat exchangers and pumps designed to produce significantly more steam than the machine requires during manufacturing steps.
This new solution allows the tower dryer to self-sufficiently generate all the steam it requires for optimal operation. Consequently, the surplus steam can be efficiently reused by other thermal machines, located in proximity of the recovery system.

To further reduce the machine emissions, the process gas heating system can be electrical (instead of using fuelled burner), consisting of an electrical battery (heater) coupled with a finned heat exchanger. 
The electric battery, located outside the dryer circuit, heats the diathermic oil circulating within the system. The heated diathermic oil then flows through the heat exchanger, consequently heating the process gas.

Embracing positive impact on sustainability is Comas driving force for delivering, through innovation, automation and digitalization, greater efficient technologies contributed not only to achieve excellent final products, but to accelerate a pivotal and responsible transformation to safer and cleaner industrial processes, necessary for both the industry and society at large.
