EVAPOR is a Spinning Cone Centrifugal Flow Thin Film Vacuum Evaporator which consists of a cantilevered conical rotor horizontally set in the process chamber and peripheral components resulting in a compact and unique liquid evaporator / concentrator designed for special applications.


  • Low-temperature evaporation and extremely short residence time result in an ideal equipment for heat-sensitive quality products
  • Large overall heat transfer coefficient resulting in a high evaporation capacity per equipment
  • Foaming is minimized by centrifugal force
  • High concentration ratio
  • Small product hold-up inside the equipment
  • Evaporation surface can be monitored during operation.
  • Hygienic design with easy evaporation surface cleanability. CIP available.
  • Compact and practical design to facilitate installation
  • Ready for operation to save installation cost

Typical Applications

  • Enzyme and antibiotics
  • Pharmaceutical Intermediates
  • Herbal extracts
  • Seasoning (amino acid, yeast,soy, etc.)
  • Extract (meat, fish, mushroom, etc.)
  • Flavors
  • Tea and Coffee
  • Juices
  • Oil and fat
  • Vitamins
  • Synthetic resin
  • Juices

Operating Principle

The material to be concentrated is pumped into the equipment through a feed tube, ≈200G centrifugal force created by the spinning cone spreads the product over the entire heating surface in a very thin layer (approximately 0.1 mm), then it is collected at the outer edge of the spinning cone through a stationary paring tube and pumped out of the equipment. The centrifugal design helps the equipment to achieve higher concentration level than other types of evaporators.
Gentle evaporation under vacuum, reducing the material’s boiling point permitting evaporation to be done at lower temperatures (from 35oC) and extremely short product residence time on the heating surface (<1 second for any model) guarantee a high quality concentrated product. Inspection windows are strategically fit on the spinning cone front housing in order to allow the inspection of the product and evaporation surface during operation.
Different size models are available for the processing of value-added products such as intermediate pharmaceuticals, functional food, fine chemicals, seasonings, food and beverage.
