Abstract
A vapor compression distillation/product concentration device includes an evaporator/condenser core, with alternating boiling and condensing chambers with edge manifolds such that substantially the entirety of each plate surface is used as a heat transfer surface. Seals are conveniently formed between adjacent plates by laying a bead of liquid gasketing material such that as the plates are laid atop each other and cured, a waffle-like seal is formed surrounding the contact points between adjacent plates which interlocks the seal with the plates. A truly perpendicular fluid flow is achieved between the alternating boiling chambers and condensing chambers as each fluid traverses the entirety of each chamber in a unidirectional flow as it passes through the evaporator/condenser core.
