A LONG-STANDING AND CLOSE PARTNERSHIP WITH NESTLÉ ON HEAT RECOVERY OPTIMIZATION SHOWING IMPRESSIVE RESULTS IN ENERGY SAVINGS AND CO2 REDUCTIONS!
Anytherm delivered its third consecutive large exhaust air heat recuperator to Nestlé, marking another milestone in our ongoing partnership. The latest unit, identical to the one previously delivered to a Nestlé spray drying facility, was installed last week, while an even larger unit was successfully supplied to another Nestlé site a few months ago.
The three heat recuperators each feature significant heat recovery capacities of 1.3 and up to 2 Megawatts. With annual energy savings of up to over 20’000 MWh in total, these systems reduce CO2 emissions by approximately 5’000 tons per year – equivalent to the emissions of about 2’000 cars or the energy consumption of about 2’100 households per year.
With imposing dimensions of about 10x3x4 meters and a weight of 13 to 17 tons per unit, the installation process of the heat recuperators involved inserting the housing by crane through the roof – a spectacular procedure, the safety of which was previously calculated by Anytherm using FEM analysis and then tested in reality at Anytherm’s production site by performing a dynamic load test.
Our expertise in heat recovery process technology has enabled us to develop heat recovery system that combine maximum durability with optimized performance and efficiency. The heat recuperators are designed to maximize the efficiency of heat recovery by going into condensation, achieving increased energy savings.
The heat recuperators consist of heat exchanger elements connected in series to maximize heat recovery, thermally insulated inlet cones to minimize energy losses, and specially designed outlet cones for effective condensate drainage. The heat recuperators are equipped with sight glasses for visual inspection and a CIP (Cleaning in Place) system to remove powder accumulations from the heat transfer surfaces. In collaboration with Nestlé, Anytherm conducts CIP studies to further optimize the cleaning process.
These heat recovery solutions result from our close cooperation with Nestlé, focusing on the optimal integration of heat recovery systems, leveraging Anytherm’s expertise in pinch analysis methodology, technical feasibility, cleanability, and optimal integration into spray drying processes. This joint initiative represents a significant contribution to enhanced sustainability in spray drying processes worldwide. We thank Nestlé for their trust and the excellent collaboration!
