WORKING PRINCIPLE OF CONVAP
The product is pumped into the lower end of the CONVAP heat exchange cylinder.
Heating media flows in the annular space between the heat-transfer wall and the insulated jacket.
Mechanical agitation,provided by the revolving blades, creates the conduction and convection conditions
required for heat transfer.
The scraping blades, centrifugal action of the rotor, and vacuum all contribute to vaporization
which occurs in the custom designed vapour dome.
The CONVAP, a modified CONTHERM, functions as a compact, scraped-surface evaporator.
It is particularly suited for concentrating viscous, sticky or heat sensitive products, and is normally operated
under vacuum conditions as the final evaporation stage to achieve very high concentrations of solids.
