EMMERICH, Germany – Probat, the world market and technology leader for coffee processing plants and machinery, introduces an energy-saving, high-performance solution for the reduction of odors from the cooling exhaust air, specifically catered to the requirements of the coffee industry. A responsible use of natural resources and the minimization of pollutant inputs into the environment are in the foreground of PROBAT’s holistic approach to sustainability.
This objective also plays a central role in the development of new environmental technologies. The results are trend-setting product solutions that guarantee a consistently high coffee quality based on environmentally friendly and energy-saving roasting technologies. The new Proair cooling exhaust air treatment system is the latest addition to PROBAT’s future-proof product portfolio.
The innovative Proair injector makes odor components no longer perceptible to the human nose, requires only little energy and is particularly space-saving. It can easily be integrated into the roasting process – while indoor and outdoor installation is possible – and is able to treat airflows of up to 220,000 cubic meters per hour.
For coffee roasting companies it is becoming more and more of a challenge to comply with regulatory requirements, especially in densely populated areas where authority regulations are particularly stringent also with regard to odorous emissions. In order to meet growing customer demands for a solution to remove these odors from the exhaust air released during the cooling process, PROBAT partnered up with Aerox, a company with a vast experience in the field of odor reduction. Together they developed the Proair cold plasma injector specifically adapted to the requirements of the coffee industry.
Proair works without the use of regenerative catalytic or thermal oxidation technology, based solely on a non-thermal plasma process. Ambient air is forced through a three-stage filter for purification and a heater for moisture control, before it is passed through a series of cold plasma modules, which split the water and oxygen molecules, transforming them into active oxygen. Inducted into the process air exhaust duct, these so-called free oxygen radicals trigger an odor reduction as soon as they come into contact with the offensive odor molecules of the cooling exhaust air. The resultant oxidized molecules can no longer be detected by the human nose.
Thomas Elshoff, R&D Engineer in charge at PROBAT, explains why it was high time to introduce this technology to the coffee industry: “In the past the focus was mainly on treating roasting exhaust air. With a shift of regulations also to odor emissions, together with our partner Aerox we developed this solution to help our customers eliminate unwanted odor components from the cooling exhaust air. The Proair injector reduces odor emissions by at least 50 percent while requiring only little energy and space. With three different sizes and its easy integration into any roasting process, it is the perfect solution for roasteries with medium to large production capacities.”
The official release of Proair takes place on April 15 during the HEAT Series session on this new odor reduction solution of PROBAT. The stream can be followed live via the company’s Facebook and YouTube channel where it will be available also afterwards.
