Koch Extraction Technologies, Inc.ciprocating Plate Column consists of a series of perforated plates with large diameter holes and high free cross sectional area mounted on a reciprocated central shaft. The reciprocating motion imparts energy to the liquids, creating droplets and thus providing interfacial area so that mass transfer can take place. Along with the perforated plates are periodic baffle plates that suppress axial mixing. This promotes a close approach to true countercurrent plug flow and minimizes the height equivalent to a theoretical stage (HETS) of the column.

The entire series of perforated and baffle plates is assemble in a single cartridge, which is suspended from the drive motor on top. There are no internal bearings or guide bushings, and all maintenance is performed outside of the column. The drive unit is equipped with a variable speed motor to allow optimization of the column performance.

According to the supplier, the reciprocating plate motion of this column produces uniform shear mixing across the entire column cross section, making the column particularly suitable for systems which tend to form stable emulsions, such as fermentation broths.

The column shell can be constructed of carbon steel, stainless steel or higher alloys, Teflon, glass-lined steel, or FRP. The internal plate stack can be constructed of stainless steel, higher alloys, Teflon, or FRP.
