Abstract
A method and apparatus for degassing a high viscosity fluid wherein a vacuum chamber is oriented vertically and adapted for receiving a fluid at its top end and discharging it from a reservoir at its bottom end, the chamber having an assembly having a slotted wide-mouthed nozzle and a channel slide member mounted within the top end so as to receive a fluid fed into the chamber. The nozzle is adapted for spreading the fluid onto the surface of the slide member which is angularly positioned downwardly towards the reservoir such that fluid on the slide member surface exhibits laminar flow as it moves downwardly. A vacuum drawn on the chamber effects a release of any gaseous materials contained within the fluid as it moves down the slide surface and into the reservoir where it may be drawn out for application by one or more nozzles.
