Thin-film evaporator technologies from Kremsmueller
Safely separate and recycle material mixtures
Thermal separation processes are essential for the recovery of valuable ingredients from waste and old materials or the efficient extraction and further processing of raw material components.
Thin film evaporation reliably separates even the most difficult material mixtures, turns the components into valuable raw materials and is extremely versatile for
- Fibre and cellulose industry
- Environmental technology
- Chemical industry
- Beverage and food industry
- Sugar and starch industry
- Polymer industry and petrochemicals
Optimum raw material extraction from all material mixtures
At Kremsmueller, you get distillation, evaporation and drying systems that are precisely tailored to your area of application – with one contact person from the initial idea to the last screw.
Our thin-film evaporator technology comes into play when the processing of materials needs to be complete and clean.
With the know-how of Kremsmueller’s experts, equipment is created that extracts the maximum amount of raw materials from a wide variety of material mixtures.
This guarantees maximum efficiency.
The basic principle:
In a thin film evaporator, the liquid or viscous media run down the walls of a heated cylinder, where the more volatile components evaporate and are then condensed again.
Solids and less volatile substances remain behind. Kremsmueller’s specialised machines reliably separate even complicated mixtures of substances – thanks to a precisely coordinated apparatus design and the control of dwell time and temperature.
The result: You obtain the maximum amount of recyclable materials from your source material in the most efficient way.
Customized rotor systems for efficient evaporation
It is also extremely important to choose the right rotor system, which creates turbulence in the liquid inside the machine. This ensures a high level of heat transfer and prevents undesirable effects such as crystallisation or polymerisation.
- Rigid rotors: Areas of application primarily in the food industry
- Nacheil rotors, metallic or PTFE tipped: Generally used in the chemical industry and for higher viscosities
- Pendulum beater: for saline solutions

LIQUIFILM
Falling film evaporators are particularly suitable for high evaporation rates, temperature-sensitive liquids, which can be evaporated very gently due to the low temperature difference and short process times.
LIQUIVAP
Enables gentle separation of liquid mixtures, e.g. greasy and oily components, oils and waxes with solid impurities or polymers.
LIQUIDRY
Sludge is a typical application for thin film dryers. In the course of further environmental requirements towards “zero liquid discharge” (ZLD), ever higher process temperature requirements are necessary. Kremsmueller is able to realise 500 °C and more for sludge drying in horizontal thin film dryers.
LIQUIMOL
Short path evaporators/molecular distillers are used, for example, to extract lactic acid via distillation and evaporation.
Lactic acid (polylactic acid, PLA) serves as a raw material for the production of bioplastics and replaces petroleum products.
If your machine has to be at its destination on time, even with a short lead time, the Kremsmueller team will get up to speed - solution-orientated and cooperative.
