PRODUCTION APPARATUS FOR MICROORGANISM-CONTAINING CAPSULE

摘要

PURPOSE:To obtain microorganism-containing capsules having uniform particle diameters, by extruding microorganism suspension from the inner wall of a nozzle, releasing a film-forming agent solution along the outer wall of the nozzle, forming liquid drops which cover the microorganism suspension with the film-forming agent solution and introducing them into a gelatinizing solution bath. CONSTITUTION:An inverted cone type rotary container 1 is set on the top of a hollow vertical shaft 2 and a great number of nozzles 7 are set at equal intervals at the outermost peripheral part of the rotary container 1. A pipe 12 to feed a film-forming agent solution is laid at the central part above the rotary container 1, a solution bath to feed the film-forming agent solution is set at a lower top part of the rotary container 1 and the film-forming agent solution is introduced from the lower top part to the nozzle 7 with rotation of the rotary container 1. A microorganism suspension is fed from a hollow part of the hollow vertical shaft 2 to an inner part of the rotary container 1.
