摘要

An apparatus for cultivating aerobic microorganisms using low pressure air as a source of oxygen and as a stirring medium, comprising a plurality of separate platforms located one above the other and each having a pair of closed fermentation chambers separated horizontally, which extend longitudinally, and a corridor in the space between each pair of chambers, an inlet tube at one end of each chamber to introduce the culture mixture therein and an outlet tube at the other end of each chamber to remove the crop mixture, and a pump in said inlet tube to move the culture mixture along the chamber, a low pressure air duct extending longitudinally in each chamber along its entire length, together with its lower portion and next to it that is located away from said corridor, input conduit means to supply air to each of said conduit s of air, outlet conduction means for extracting air from each of the air ducts, pumping means in one of said ducting means for causing the air to travel through each and every one of said air ducts. Air, each of said chambers having in the lower portion thereof a plurality of agitation zones spaced longitudinally from one another along the entire length of each chamber, each of said zones being defined by a pair of separate partitions. Each other and the floor of the chamber, and extending from one side to another of said chamber, each zone having a plurality of transversely separated air bubblers, adjacent to the bottom thereof, an air pipe connected to each bubbler, and, disposed outside the zone, an air feeding tube connecting said air duct with said air pipes, each chamber being adapted to contain culture mixture up to a height of sufficient to fill said zones, and the culture mixture in each zone being adapted to be lifted upwards therein by the low pressure air discharged from said bubblers and to overflow through the upper part of the zone, thus achieving that the mixture circulates continuously through the zone, and the height of each zone is related to the pressure of said low pressure air to effect said continuous circulation, and said pump serving the culture mixture to gradually move the culture mixture to all along the length of each camera.
