More efficient and sustainable drying: Dryer trio for sugar production
Pfeifer und Langen, Germany
Sector: Sugar industry, food industry
Challenge: Relieve the existing high-temperature drying process and simultaneously reduce CO2 emissions.
Solution: A drying system consisting of three belt dryers that uses three different heat sources to ensure flexible and efficient drying.
Dryer used: 3x Belt dryer type BT 1/6200-30
Product to be dried: Sugar beet chips
Challenge
As one of Europe's leading sugar producers, Pfeifer & Langen produces nearly 1.9 million tonnes of sugar and agricultural products annually. A key part of the sugar production process is drying sugar beet pulp. The goal was to reduce the load on the existing high-temperature drying system while also cutting CO2 emissions. In addition, existing residual energy was to be used efficiently and odour emissions minimised.
Solution
To meet these challenges, Pfeifer & Langen GmbH & Co. KG decided to install a new low-temperature drying system (NTT) at its Jülich plant, consisting of three stela belt dryers. These were integrated into the existing pulp transport route.
A special technical feature is the use of three different heat sources to feed the dryers' hot water heat exchangers. This ensures flexible and efficient drying of the sugar beet pulp, depending on the locally available heat capacity. The total output of the dryers is around 24 MW, which means that 75 tonnes of wet material per hour can be dried from a moisture content of 70% to 55%.
Manufacturing and assembly
The three stela belt dryers were assembled into a drying system with a total length of 90 metres and a width of 6.2 metres, with each individual dryer measuring 30 metres in length. The components were delivered pre-assembled to enable delay-free and weld-free assembly. The modules were moved into position using a tower crane. Under the supervision of a stela chief engineer, the assembly was finally completed on schedule.
“The collaboration with Stela was positive throughout. From start to finish, everything went smoothly, directly and without complications. We were extremely satisfied with the services provided and appreciate the efficiency and professionalism that stela brought to the collaboration.”
Gerrit Bossmann, Technical Office, Pfeifer & Langen
Conclusion and outlook
The new low-temperature drying system at the Pfeifer & Langen sugar factory is an exemplary project for sustainable innovation: since investing in stela belt dryers at the Jülich site, 50% less energy is used to dry sugar beet pulp.
