Improved desolventizer of the countercurrent type. Solvent laden solids enter a closed chamber wherein they are continuously agitated by stirrers. Steam from below rises up through a porous deck and the solids thereon whereupon the steam condenses to release its heat of vaporization thereby aiding in the evaporation of solvent in the solids. The desolventized solids exit the chamber through a discharge passage. The deck includes generally radially spaced apart, substantially parallel stainless steel bars supported on substantially radially extending carbon steel supports. The spaces or slots thereby defined by the bars define an open area covering up to about 30% of the surface area of the deck. The gaps between the bars are sufficiently narrow so as to reduce the likelihood of the solids being worked into the gaps. The bars have a cross sectional profile having a greater width at their top and a lesser width at their bottom so as to promote clearing of any material that might have been worked therebetween from the top side.
A desolventizer apparatus including:
In a desolventizer apparatus including a deck surface area, a steam supplied chamber below said deck surface area, and a treatment zone above said deck surface area wherein in said treatment zone steam communicated from said chamber is mixed with meal, an improved deck, said deck comprising a plurality of spaced bar members, each of said bar members comprising
An improved desolventizer comprising:
An improved desolventizer for desolventizing solvent laden solids and having a closed upper chamber, a lower chamber below said upper chamber, and a steam source in fluid communication with said lower chamber, wherein the improvement comprises:
A desolventizer comprising:
In a desolventizer of the type having a chamber adapted for reception of solvent-laden meal therein, a shaft extending through said chamber, a stirrer rotatably mounted on said shaft and adapted to stir said solvent laden meal thereon and allow passage of steam therethrough for treatment of said meal in said chamber, the improvement wherein said deck comprises
