ABSTRACT:
The disclosed apparatus relates to the microbiological industry and can be used in the food and medical industries, as well as in agriculture for utilization of the waste and refuse of animal-breeding farms. The apparatus comprises a sealed vertically arranged vessel divided into a vertical row of sections by perforated partitions of two kinds mounted alternatingly height-wise of the vessel. Some of the partitions are made as discs arranged so that annular gaps remain between them and the vessel housing, while other partitions are in the form of flat rings; the annular gaps and the central openings of the flat rings serve as ducts for the passage of a nutrient medium into the underlying sections. Mounted above the perforated partitions are cylindrical shells serving as intermediate accumulators for the nutrient medium, and blade-type agitators adapted to urge the nutrient medium toward the annular gaps and central openings. This constructional arrangement of the apparatus provides for creating in each section appropriate conditions for intense growth of the microorganisms, and thus for enhancing the throughput of the apparatus.
