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.

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.
