stirred tank bioreactor design
The approach to design and development of single-use stirred tank bioreactors described herein was based on good engineering principles. Focusing on every critical component and function has ensured that the final product can provide a viable alternative to traditional stainless steel cleanable bioreactors.
Summary • Aware of standard geometry of a stirred tank bioreactor • Know the basic features of a stirred tank bioreactor • Understand working of the agitation system • Agitator design and operation • Components of the oxygen delivery system • Foam control • Temperature control system • pH control system • Cleaning and
Traditionally, stirred tank design is driven by the oxygen transfer capability needed to achieve cell growth. However, design methodologies available for stirred tank fermentors are insufficient and many times contain errors. The aim of this research is to improve the design of production scale stirred tank fermentors through the development

The fermentor (bioreactor) types used extensively in industries are the stirred tank fermentor, airlift fermentor, and bubble column fermentor. (i) Stirred Tank Fermentor : Stirred tank fermentors consists of a cylindrical vessel with a motor driven central saft that supports one or more impellers.
The CSTR bioreactors have a modular design, built with high-quality materials and robustness in mind. Bioprocess Control has developed a series of continuous stirred tank (CSTR) bioreactors specifically designed for scientists and process engineers to simulate full-scale fermentation processes in a laboratory- or small pilot-scale.

On the basis of mode of operation, a bioreactor may be classified as batch, fed batch or continuous (e.g. a continuous stirred-tank reactor model). An example of a continuous bioreactor is the chemostat. Organisms growing in bioreactors may be submerged in liquid medium or may be attached to the surface of a solid medium.
The continuous stirred-tank reactor (CSTR), also known as vat- or backmix reactor, or a continuous-flow stirred-tank reactor (CFSTR), is a common model for a chemical reactor in chemical engineering.A CSTR often refers to a model used to estimate the key unit operation variables when using a continuous agitated-tank reactor to reach a specified output.
A bioreactor system for suspension culture consists typically of a bioreactor vessel which is equipped with a drive for the stirrer in case of stirred tank bioreactors, a measurement and control unit, a heating and cooling circuit, gas supply and removal, feed tanks, sampling and harvest systems, sterile couplers, ﬁttings, piping etc.
Design and Performance of Single-Use, Stirred-Tank Bioreactors Alvin W. Nienow, Bojan Isailovic, and Timothy A. Barrett S ingle-use components and systems have been incorporated into many bioprocesses as an alternative to cleanable, reusable systems. A wide range of publications have detailed the reasons for this trend toward a single-use approach.
Equipment Design CSTRs consist of a tank, usually of constant volume, and a stirring system to mix reactants together. Continuous stirred-tank reactors are most commonly used in industrial processing, primarily in homogeneous liquid-phase flow reactions, where constant agitation is required.
