Verdampfer erhöhen die Prozessflexibilität, Produktqualität und Produktivität.
Ein weltweit führender Hersteller von löslichem Premium-Kaffee produziert hochwertigen, zu 100 % kolumbianischen gefriergetrockneten Kaffee für den weltweiten Verbrauch. Um nachhaltigere Lösungen für sein Werk zu finden, hat sich das Unternehmen mit Alfa Laval zusammengetan und einen AlfaVap-Verdampfer mit einer Kapazität von 4.000 l/h angeschafft, um Kaffeeextrakt für die anschließende Gefriertrocknung zu konzentrieren. Das Ergebnis? Kompaktere, wirtschaftlichere Verdampfungssysteme, energieeffiziente Separatoren und Dekanter sowie eine langfristige Partnerschaft, einschließlich Service und Support.

Process flexibility and product quality key
The coffee company wanted to improve process efficiency and meet its sustainability goals. To enhance its sustainability credentials, the coffee maker installed a compact, double-effect Alfa Laval plate evaporator. More economical than shell-and-tube evaporators, the plate evaporator extracted the soluble compounds from the fresh, roasted 100% Colombian arabica dissolved in hot water yet retained the coffee’s intensity and flavour. “The Alfa Laval plate evaporator improved the production process at our plant and delivered great results – exceptional coffee taste and aroma,” says the project manager in charge of factory development. “It easily integrated with our plant’s control systems, making operation and maintenance easy.”
Our business relies on Alfa Laval. So do coffee aficionados the world over.

33% lower installation costs than shell-and-tubes
About one-third the height of shell-and-tube evaporators, the Alfa Laval evaporation system cut installation costs by 33%. Unlike shell-and-tubes, no costly, time-consuming, last-minute welding is required. Fully assembled and factory tested, to the Alfa Laval evaporators ensure trouble-free assembly on site. Its reduced size means low hold-up volumes, which increase the evaporation rate and enhance product quality.
Energy-efficient, space-saving concentration
To prevent any loss of product quality due to thermal impact, the Alfa Laval evaporator removes water from the coffee under vacuum conditions at very low temperatures (below 66°C or 150.8°F). Its compact size minimizes energy losses when transporting the coffee through the evaporator and thermal losses due to shorter exposure to heat transfer surfaces
Large evaporator increases capacity, pilot unit tests new products
Success with this evaporator prompted the coffee producer to invest in a 10,000 l/h-capacity Alfa Laval plate evaporator as well as a 200 kg/h pilot unit for product development.
Glocal support and service – and sustainable optimization
Fast response to the company’s requests for support and service comes from local Alfa Laval service engineers and the nearby service centre as well as through remote assistance from Alfa Laval’s evaporation experts in Denmark and Italy.
