Oil-free Air Conveying In Coffee Roasting Equipment

Posted by Aerzen At Aerzen USA on Mon, Jun 02, 2014 @ 08:57 AM
Since its foundation in 1868 the Probat-Werke has concentrated with more than 600 employees worldwide on roasting machines and equipment for coffee and food industry. Until today, the world market leader has sold more than 110,000 roasting machines – from manual global roaster via fully automatic largescale roasters up to the new tangential roaster Jupiter Hybrid with which the most diverse roasting profiles can be prepared in one roasting machine.
For transport of the coffee, Probat prefers the pneumatic conveyance. As the
conveying air is in direct contact with the product, it has to be absolutely oilfree. For production of the conveying air as negative pressure, Probat has used Aerzen units since 1996.


In September 2012, Probat opened a new Research and Technology Centre. There, the conveying air required in the roasting machines is generated by two Delta Blowers Generation 5 and one Delta Hybrid. Upon storage of the green coffee into silos with overpressure between 1,000 and 2,000 mbar, the Delta Blower is used, also during transport to the roasting machine with positive pressure.
The Delta Hybrid is responsible for transport of the particularly sensitively
roasted beans to the roasted coffeesilos and to bagging station with negative pressure as well as for transport to grinding plant with overpressure. The Delta Hybrid unit generates a negative pressure of 300 mbar on suction side as well as an overpressure of 600 mbar on discharge side. Therefore, a conventional blower unit could be replaced acc. to the principle “Two become
one”.
Again, two Delta Blowers transport the ground coffee to the ground coffee silos and to the packaging machines with negative pressure. As an alternative, however, the Delta Hybrids can also be used. The required differential pressure is decisive for the selection dependent on the piping length and the specific energy advantages of the Hybrid.

All Aerzen units are fully automatically integrated in the process of the roasting equipment and are switched via a superordinated intelligent SPS control depending on the program. The respective blower units are driven with a constant volume flow whereby the pressure is built up depending on conveying capacity and pipe length. Thanks to a bypass solution, Aerzen
had developed together with Probat, a part of the volume flow can be led back from discharge to suction side for the positive pressure units.

A Turbo Blower for the Base Load, PD Blower for the Peak Load

Posted by Tom McCurdy on Mon, Apr 15, 2013 @ 10:27 AM

A biological municipal wastewater treatment plant with a considerably fluctuating discharge quantity can only perform its function with utmost energy efficiency and reliability if the process air consumption of the aeration basin can be adjusted continuously and is fully automated in order to deal with widely fluctuating load quantities. The example of the wastewater treatment plant shows how this is achieved with the use of a speed controlled Aerzen turbo blower.

More pressure for Aerzen Process Gas Compressors

Posted by Pierre Noack on Thu, Mar 21, 2013 @ 11:35 AM

Due to a new bearing and shaft design it is possible to increase the maximum admissible differential pressures to 25 bar in the process gas compressors VRa 236 H and VRa 336 H. Thus, with a multi-stage unit discharge pressures of up to 53 bar abs. can be reached.

Real-time Condition Monitoring For Blowers And Compressors

Posted by Inquires At Aerzen US on Mon, Jun 25, 2012 @ 09:21 AM

The Aerzen iAir Remote Monitoring System (RMS) is a comprehensive monitor that can be attached to any blower or compressor to capture real-time activities and conditions. Based on industrial cellular technology, the RMS can function in any location with cellphone coverage for both indoor and outdoor applications. The system is easily installed and linked directly to your cell phone for up-to-the-minute condition reports and notifications. This allows for peace of mind and troubleshooting when you are not accessible to the equipment.
