Gentle concentration for heat-sensitive, viscous, and high-value products—at evaporation temperatures as low as 35 °C.
EVAPOR combines a spinning cone with vacuum thin-film technology to deliver ultra-short residence time (typically < 1 second) and a uniform film (≤ 0.1 mm) across the heating surface. The result: fast, low-temperature evaporation that protects active compounds, minimizes foaming, and reaches higher final solids and viscosities than traditional plate or tubular systems.

Why EVAPOR

• Protects product quality
  Low operating temperatures and sub-second residence time safeguard flavor, aroma, color, enzymes, and actives.

• High capacity in a compact footprint
  A large overall heat transfer coefficient drives high evaporation rates per unit of equipment.

• Foam under control
  Centrifugal force from the spinning cone suppresses foaming—ideal for botanicals, extracts, and protein solutions.

• Concentrates to higher viscosities
  Achieve higher soluble-solids levels than traditional plate/tubular evaporators, even with viscous streams.

• Low hold-up, easy CIP
  Minimal product volume inside the unit reduces losses. Hygienic design with excellent surface accessibility and CIP capability.

• See what’s happening
  The evaporation surface can be monitored during operation for confident, repeatable runs.

• Proven at scale
  620+ units installed worldwide across pharma, nutraceutical, fine chemical, biochemical, and food & beverage applications.

How It Works

EVAPOR is a single-effect, vacuum thin-film evaporator using steam as the heating medium. Feed enters at the base of a hollow disc spinning cone mounted on a horizontal cantilevered shaft. Centrifugal force spreads the liquid into a uniform, ultra-thin film over the heated surface. Under vacuum, the product instantaneously reaches its boiling point, evaporating solvent in < 1 second.
Concentrate is collected at the periphery via a stationary paring tube and discharged by pump, while vapor flows to a condenser and exits as condensate.

Key operating features:

• Evaporation temperature: as low as 35 °C (vacuum-dependent)

• Film thickness: ≤ 0.1 mm

• Residence time on heat surface: < 1 second

• Heating medium: steam

• Configuration: single-effect, centrifugal thin-film under vacuum

   

Typical Applications

• Pharma & Biopharma: penicillin/antibiotics, intermediates, enzymes, proteins, vitamins, active ingredients

• Botanicals & Nutraceuticals: herbal and plant extracts, natural seasonings, flavors

• Food & Beverage: tea, coffee, juices, fruit/vegetable extracts, meat/fish/mushroom extracts

• Chemicals: synthetic resins, fine/organic/inorganic chemicals

Design & Hygiene

• Hygienic construction with smooth surfaces and CIP options

• Small product hold-up reduces losses and speeds grade changeovers

• Compact, practical layout simplifies installation and service

• Operator visibility of the evaporation surface during production

What Sets EVAPOR Apart from Traditional Evaporators

• Lower thermal impact (vacuum + sub-second residence time)

• Better foam management (centrifugal film formation)

• Higher final solids/viscosity capability

• Higher overall heat transfer coefficient → more capacity per unit
