The ES Junior series of continuous vacuum driers are the ISVE mini-driers traditionally used by small craftsmen.
They enclose all the technology and experience developed over twenty years of research into the application of the vacuum process in the treatment of wood.
The machine, operating at low temperatures, allows the timber to lose its water content without subjecting it to thermal changes which can cause cracking and warping.
The evaporated water which remains in suspension in the container keeps the drying material surface continuously humidified, avoiding in this way the formation of small cracks which, in other drying systems is quite frequent.
The humidity level which is necessary between environment and material is constantly maintained by a condenser which precipitates the steam in suspension.
Vrieco-Nauta vacuum dryers were developed from the already successful conical screw mixer line. The superior mixing quality of the Vrieco-Nauta mixers is utilized to efficiently present fresh product to the heated surface area. Heat is transferred into the product through a jacketed vessel wall causing solvents or moisture residues to evaporate. The entire vessel is run under vacuum to further aid in moisture removal by lowering the saturated vapor pressure.
