A fermenter is an apparatus that maintains optimal conditions for the growth of microorganisms. The main function of the fermenter is to provide a controlled environment for the growth of a pure culture or of a defined mixture of microorganisms or animal cell to obtain the desired product. Different parts of fermenter:- 1) Fermenter Vessel: A suitable vessel is used to carry out the whole fermentation process. The vessel is capable of being operated aseptically and meet the containment

CHAPTER 1 INTRODUCTION At first glance the idea of running an engine on air seems to be too good to be true. Actually‚ if we can make use of air as an aid for running an engine it is a fantastic idea. As we all know‚ air is all around us‚ it never runs out‚ it is non-polluting and it is free. An Air Driven Engine makes use of Compressed Air Technology for its operation. Compressed Air Technology is now widely preferred for research by different industries for developing different drives for different

Describe the methods used to ensure that all pipes‚ cocks‚ valves and other fittings used for indicating water level are clear and are in good working order. Methods used to ensure boiler is in working order. Before a new boiler is initially fired‚ it should be given a complete and thorough inspection on both the fire side and water side.

project has mainly concentrated on this difficulty‚ and hence a suitable hydraulic unit has been designed. Such that the vehicles can be stand the floor land without application of any impact force. By pressing the button in the dashboard‚ the solenoid valve activates the hydraulic jack automatically. The fabrication part of it has been considered with almost case for its simplicity and economy‚ such that this can be accommodated as one of the essential tools on automobile garages. INTRODUCTION

and Instrumentation Drawing (P&ID) tells what they do. P&IDs “show the interconnection of process equipment and the instrumentation used to control the process”.1 Sets of symbols are used to depict mechanical equipment‚ piping‚ piping components‚ valves‚ equipment drivers and instrumentation and controls. These symbols are assembled on the drawing in a manner that clearly defines the process. The instrumentation and control (I&C) symbols used in P&IDs are generally based on ISA-5.1-1984-(R1992)

to operate. 2) The energy source (electric motor or combustion engine) powers a compressor which forces conditioned air into a pressurized storage tank (which serves as the system reservoir). Constant pressure‚ maintained by pressure regulator valve‚ is automatically adjusted by motor-driven air compressors during system operation. No return lines to a storage tank like hydraulic systems‚ air is vented to atmosphere. The load device in this system changes the mechanical energy of air into linear
