About digital control of fermentation process

1. COMPUTER CONTROL OF FERMENTATION PROCESS SUBMITTED BY: K . Sanjay(BP211525 ), II M. Sc. Applied Microbiology, Sacred Heart College(Autonomous), Tirupattur . SUBMITTED TO: Dr. P. Saran raj, Head of Department of Microbiology, Sacred Heart College(Autonomous), Tirupattur .

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. FERMENTOR IMPORTAT PARTS

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 Application:
