Abstract:

Continuous reaction with immobilized enzyme beads is carried out in an enzymatic reactor providing for continuous reaction accompanied by continuous cleansing of the immobilized enzyme beads and continuous recycling of the cleansed-immobilized enzyme beads for reaction. The reactor comprises a reaction chamber having a screw mounted coaxially within a shell having first and second ends, means at the first end for introducing immobilized enzyme beads and fluid reactant material, means at the second end for removal of product, means at the second end for lifting of immobilized enzyme beads and dropping them through a reaction chamber and means for conveying cleansed immobilized enzyme beads from the cleansing chamber to the means for introducing.

Abstract:

An aerobic digestor for rapidly and efficiently composting waste vegetation and the like has a rotatable drum mounted on a horizontal transverse axis at the midpoint of the length on a frame spacing it above the ground a distance sufficient for rotation; a fixed end of the drum mounts a perforate tube coaxially in the drum between the ends and holes in the fixed end and the removable end of the drum admit air for composting to the perforate tube through adjustable shutters; material being composted in the drum receives air through the tube perforations and may be end-for-ended periodically with the drum at which time the shutter on the end being lowered may be closed to force air up through the dropping charge of waste material.
