Coffee blender warms to heat exchangers
8 Nov 2012
London – HRS Heat Exchangers, working with heat transfer consultancy Kapp Nederland, has supplied heat exchangers to DE Master Blenders 1753 for its new pilot plant located in Utrecht, the Netherlands.
Based on R&D data from the international coffee and tea company, Kapp Nederland and HRS designed and manufactured the DTA series heat exchangers for the heating and cooling units in the new pilot plant.
The researchers wanted a flexible solution for heating/cooling the produced extract, and the DTA series provides that for a large fold (60) in the flow, accordig to HRS.
The shell-and-tube heat exchangers have been interconnected with manifolds and mounted on a special frame, which allows the heating and cooling units to be situated close to the rest of the extraction unit. The cooling unit duty range is between 2.2 kW and 118 kW.
An extraction pilot plant at Utrecht gave the team the ability to conduct complete trials and the unique design of the plant ensures efficient heating and cooling.
Designed for food industry applications, the DTA series is a tube-in-tube heat exchanger. Product flows through the inner tube and the service fluid through the annulus between the inner and outer tube.
Because of its geometry, the heat exchanger is a true counter current heat exchanger, said HRS.
