Evaporators

Small Scale Evaporators

SiccaDania’s small-scale evaporator, the VAP250, is designed to simulate the larger-scale evaporators, making it possible to test a process at a smaller scale.
Small scale evaporator VAP250

The small-scale evaporator, VAP250, has been designed for both continuous and batch evaporation of liquid products into concentrate. The evaporation process is scalable, and the small-scale evaporator enables process simulation of larger industrial-size evaporators.

VAP250 is targeted for small-scale production as well as R&D work and is widely used by companies and universities worldwide. It is available in a standard version and features a range of optional modules, thus enabling customisation to match individual requirements.

The VAP250 is produced in sanitary design and includes a state-of-the-art solution regarding safety, easy cleaning and a sophisticated PLC-based control system. All parts in contact with products are made in stainless steel and all elastomers are food grade approved according to the GMP standards.
