Falling Film Evaporators

The SiccaDania falling film evaporator is an energy-efficient evaporator designed to remove water from a liquid to obtain a higher concentrate of solids. With a modularized design, every evaporator is customised for our customers.

SiccaDania designs and delivers highly efficient falling film evaporators ranging from pilot scale capacities to approximately 80 tons per hour of water evaporation. Our evaporation technology is designed to be energy-efficient for our customers in the dairy, starch and food industries.

Our experts have developed a modularized and standardised approach to configuring an evaporator. This results in shorter delivery and installation times while reducing the project time cycle. The evaporator is configured and designed according to the specific product requirements and our customers’ specifications.

Innovating for the future

The flexibility and expertise possessed by our experts allow for constant innovation. This innovation also applies to our fans. By using the newest fan technology, it is possible to compress the steam at a higher pressure and as a result at a higher temperature than traditional fans. With a higher temperature, it is possible to use only one calandria, thereby reducing the price and size of the plant.

An evaporator construction

A SiccaDania evaporation plant normally consists of the following:

• Feed tank and feed pump
• Pre-heating system, by plate or tubular heat exchangers
• The heat treatment system, by a tubular heat exchanger, DSI or direct steam flash vessel
• Falling film evaporator with integrated vapour separator, circulation pumps and discharge pumps
• Every evaporator is designed, engineered and constructed according to the application specifications. For non-heat sensitive products, our evaporator uses a single nozzle system which means one feed pipe per section.

For products that are sensitive to heat such as dairy products, our engineers concluded that a multiple nozzle system with a distribution plate and more feed pipes prevents heat damage to the product.

All SiccaDania processes and units are designed to be easy and efficient to clean. The evaporator is no exception. The evaporators have an easily cleanable, hygienic design with enlarged CIP nozzles which are fully welded and exchangeable, allowing for better and more efficient cleaning.

Features

• Only one calandria in many cases as the MVR fan can run with a high ΔT and enlarge the capacity range
• Integrated vapour separator design with a focus on lowering the BOD/COD values
• Internal feed pipes
• Hygienic distributor plate
• Enlarged CIP nozzles – fully welded and exchangeable – better and more efficient cleaning
• Easy cleanable hygienic design
• High rangeability
• Layout with focus on maintenance capability – easy and safe access to maintenance areas
• Layout with focus on building size-reduction

With a SiccaDania Falling Film Evaporator, you are ensured:

• Flexible heat treatment systems – to run various products on the same system
• Custom-made configurations – taking specific product requirements into consideration
• High focus on decreasing energy consumptions by reuse of condensate and flash vapour – lowering the OPEX
• Optimisation of running hours without compromising the bacterial growth – increases the up-time
