The document discusses computer control of fermentation processes. It notes that computers were first used in the 1960s to model fermentation for glutamic acid and penicillin production. There are three areas of computer function: logging process data, analyzing the data, and controlling the process. Fermenters are used widely in industries like dairy, antibiotics, enzymes, and vitamins to provide a controlled environment for microbial growth and product formation.

2. The initial use of computers in the 1960s for modelling
fermentation process control for production of glutamic
acid and penicillin production.
They are first discovered by Yamashita and Murao
Three distinct areas of computer function were
recognized by Nyiri
INTRODUCTION:

3. The main function of a fermenter is to provide a
controlled environment for the growth of
microorganisms to obtain a desired product.
It is used to large scale production in the industries.
FERMENTOR:

4. Fermenter are used in the large scale production in the most industries.
 Dairy production [milk,cheese,beer]
 Antibiotic production [penicillin,streptomycin]
 Enzyme production [amylase,protease]
 Organic Acid production [citric acid.glutamic acid]
 Vitamins production [vitamin B and A]

5.  Construction material.
 Temperature control.
 Aeration and agitation.

6. They are three distinct areas of computer function;
logging of process data.
Data analysis.
process data.
COMPUTER FUNCTION:

7. Data logging is performed by the data acguisition system
which has both hardware and software components.
 There is an interface between the sensors and the computer.
The software should include the computer program for
sequential scanning of the sensor signals and the procedure of
data storage.
LOGGING OF PROCESS DATA:

8.  Data reduction is performed by the data analysis system ,which
is a computer program based on a series of selected mathematical
equation.
 The analysed information may then be put on a print out, fed
into a data bank or utilized for process control.
DATA ANALYSIS: [Reduction of logging data]

9.  Process control is also performed a computer program
 Signals from the computer are fed to pumps ,valves or
switches via the interface.
They are two type of control:
1.DDC-Direct Digital Control.
2.SSC-Supervisory Set-point Control.
PROCESS CONTROL:

10.  DDC; It is when the fermenter is under the direct
control of the computer software.
 SSC; the use of independent controller to
manage all control function of a fermenter and the
computer communicates with the controller only to
exchange information.

11. • It is used to fermenter in the fermentation
techniques.
SENSOR:

12. Inductive sensors Inductors and inductance can
strike fear into the hearts of normally sane engineers,
but inductance is the basis for many sensing
applications.
Inductive sensors are used heavily in machine
applications to sense the proximity of a metal object.

13.  Temperature control.
 Ph control
 Dissolved the oxygen.
 Mineral/nutrient level
