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 odor reduction solution – adapted specifically to the requirements of the coffee industry – 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. With three different sizes it is the perfect solution for roasteries with medium to large production capacities.
Proair works without the use of regenerative catalytic or thermal oxidation technology, based solely on a non-thermal plasma process. The non-thermal plasma modules transform clean air into active oxygen, which is then injected into the process airflow for oxidation of odourous components. To this end, 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.
The Proair injector is 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. It works without the use of regenerative catalytic or thermal oxidation technology and offers many more benefits:
|Type (Capacity)||5, 10, 20 (5,000 - 40,000 Nm³/h)|
|Odor description||sweet and chocolaty, like iced coffee, minimal coffee and ozone smell|
|Energy consumption||0,2 - 0,5 kWh/100 kg of green coffee (depending on Proair type and environment)|
|Cooling time||no impact|
|Service parts||filter units and plasma modules|
