Falling film evaporator GEA Ecoflex

When product-sensitive and energy-saving applications are involved, the EVAPplus plate falling film evaporators are exactly the right choice. State-of-the art technology ensures high-efficiency concentration of juice from sugar beet and cane. The special feature of EVAPplus is the combination of tube and plate evaporators. The plates are arranged in such a way that two separate flow channels result: a tubular channel with 6 or 9 mm diameter for the juice and a corrugated channel for the condensing steam or
vapour. The plate packs are fully welded without the need for gaskets.

Retrofitting Robert-type evaporators

The advantages of the EVAPplus can also be used to achieve greater efficiency by retrofitting existing Robert evaporators. In most cases no changes are necessary to buildings, foundations or the static design of the plant. The calandria from the old Robert evaporator is simply removed and replaced with an EVAPplus plate pack and the respective distributor. With minimum expenditure the heating surface area and the system efficiency is considerably increased.

Simple to clean

The EVAPplus can be easily and quickly cleaned to maintain its maximum performance. Evaporators used for processing beet sugar juices are cleaned at the end of each campaign. When processing cane sugar juice, a sensible cleaning cycle is every one to two weeks.

Outstanding features

- High density of heating surface (170 m²/m³ or 240 m²/m³)
- Outstanding overall heat transfer values
- Low temperature differences
