Thermal evaporator

vacuumfalling filmprocess

Tubular falling film evaporator system for the production of concentrated fruit juices and aroma essences Single-pass design for maximal product yields Energy-efficient multi-stage system Integrated, independently controlled pasteurizer Sophisticated liquid distribution provides for long cleaning intervals Optimized CIP with high performance spray nozzles Also available with MVR and TVR options as appropriate Bucher Unipektin falling vacuum film evaporators are designed to produce high-quality juice concentrates and aroma essences. They typically combine the process steps of; pasteurisation, aroma-stripping and concentration in one system. Short processing time, low heat impact and sophisticated hygienic design make our evaporators ideal for the concentration of all kinds of fruit juices, i. e. from apples, pears, berries, grapes and stone fruits. Due to the uniquely designed liquid distributors they can handle juices with high suspended solids contents and with tartrate. The evaporators are typically multi-staged systems. Energy efficiency can be improved further by using mechanical or thermal vapour recompression (MVR or TVR). Feed liquid is pre-heated with the concentrated product and condensed vapours in various heat exchangers for maximum energy efficiency in the evaporators. Before entering the first evaporation column the product can be pasteurised to a controlled temperature for microbiological and physicochemical stabilisation.
