Automated Pilot Plant for Fermentation pra-0067

Full Title Automated Pilot Plant for Fermentation Tech Area / Field

BIO-MIB: Biotechnology and Life Sciences / Microbiology

Brief Description of Technology This pilot plant is intended for the cultivation of bacterial fungous and yeast cultures providing the specified technological processes. The plant is a single module, consisting of the fermenter with a volume of 300 liters and a leak-tight mixer with radial magnetic coupling, an additives unit, pneumatically driven isolation valves and biological filters.

An automated system based on a personal computer provides plant operation for twenty-four hours without personnel intervention by the specified program. Plant advantages are compactness, long lifetime and simple maintenance. Highly qualified specialists under the leadership of F.M. Mitenkov, Academician of the Russian Academy of Sciences, took part in the development of the plant.

Legal Aspects This development is protected by Russian patents.

Automated Commercial Plant for Molecular Distillation pra-0068

Full Title Automated Commercial Plant APMD-1 for Molecular Distillation Tech Area / Field

MAN-MCH: Manufacturing Technology / Machinery and Tools

Brief Description of Technology The field of application is fine cleaning from impurities in vacuum. APMD is a group of molecular distillation units arranged in consecutive order, which are a variety of rotor-film apparatuses. The plant has an automatic system of actuators control, providing equipment operation at optimal mode to increase the lifetime. Plants capacity for original products is 40-125 l/h.

Russian and foreign experience in the design and operation of molecular distillation plants have been used in the development and creation of the APMD-1 plant. In addition, the proposed technology has some advantages over the known foreign analogues: 1) To obtain and maintain a higher vacuum than in prototype plants, which provides the production of a high-quality product, the following design decisions are implemented in the plant:

- the drives of rotor apparatus are leak-tight step motors; - gear-type pumps are leak-tight; - there are waterlocks between apparatuses to avoid gas transfer; - there are liquid seals at the main flange joints of the plant; - there are special vacuum-tight ball-cocks with liquid seals at the rod; - the detachable joints at the path of product circulation are minimized, etc.

2) The plant allows molecular distillation of various products to be performed, because the rotor drives allow the number of rotor rotations to be controlled smoothly. 3) The use of pumps with the controlled number of rotations allows the plant capacity for original product to be changed within the wide range.

Highly qualified engineers and candidates and doctors of science (specialists in nuclear power) under the leadership of F.M. Mitenkov, Academican of the Russian Academy of Sciences, took part in the development of the plant.

Legal Aspects The development is protected by Russian patents, including the application of waterlocks between molecular distillation units, in-vessel elements of molecular distallation, etc.
