Thin Film Evaporator



Achieves high concentration and powdering of treatment liquid and solvent recovery in one pass

The Hi-Evaolator is a thin-film evaporation concentration and powdering system that can concentrate and solidify treatment liquids, despite being a thin-film evaporator with non-contact blades (scraping blades) against a heated heat-transfer wall. The treatment liquid or waste liquid is thinned by centrifugal force and heated to instantly evaporate, separating the liquid and solute components into powder. The evaporated material is cooled in a condenser and re-collected as liquid. In 1991, is was awarded the "18th Excellent Pollution Control Device" by the Director-General of the Small and Medium Enterprise Agency.


Functions and Features

・High concentration and can be concentrated to powder
・High concentration rate and improved solvent recovery rate
・Because the processing time is short, it is not easily affected by heat.
・One unit can perform the roles of both concentrator and a dryer.
・Continuous operation in Vacuum and low temperature is possible.

Field of application

High evaporators are used in a wide range of fields such as industrial waste liquid treatment, solvent recovery and reuse, and food concentration processes.


Treatment of factory waste liquid.

・Separation of residue, bye and glue of waste liquid for dyeing
・Separation and recovery of salts from exhaust gas cleaning liquid
・Recovery of concentrated powder of valuable heavy metals or valuable materials
・High concentration and volume reduction of active mud residue
・Concentration of raw materials for nuclear radioactive liquid waste and organic waste liquid


Treatment of highly concentrated food waste liquids

・Concentration of waste liquid of soybean broth and powdering of active ingredients
・Shochu lees
・Salt-containing wastewater


Solvent recovery

・Solvent recovery from cleaning waste liquid for painting
・Separation of DMF/MMA from synthetic fibre raw materials
・Solvent/polymer separation from resin/polymer waste liquid
・Final process of PCB treatment equipment
