Abstract
A rotary column is rotatably mounted on a hollow shaft having orifices and the shaft is journaled in a reaction vessel. The rotary column has an outer net around the shaft and a space defined by this outer net within the rotary column is divided by partition plates provided with many through-holes into several compartments to be loaded with carriers and immobilized enzymes. The reaction vessel is provided radially outside the compartments with a top cover so that carriers and immobilized enzymes may be easily and evenly loaded into the rotary column. An end surface of the rotary column that is remote from the drive mechanism is provided with a lateral cover. There are provided hydraulic cylinders to tilt the rotary column. Within the reaction vessel, the outer net of the rotary column is provided with rollers adjacent to the lateral cover. Furthermore, there is provided a deaerating pipe within the rotary column and the orifices of the hollow shaft are so dimensioned that, nearer a solution outlet, the diameters of the orifices are larger.
