FBD  Question and  answer for interview preparation fresher amd experience..

1What is full form of SCADA?
The full form of supervisory control and data acequisition system.

2 Which Principle work in FBD,FBP,FBE?
The major principle of FBD,FBP,FBE is fludization process means that product are drying in air suespension.

3 What is diffrence between FBD,FBE?

FBD                                                                     FBE

1 FBD You can drying only   1 FBE you can drying and also Top spray and bottom spray

2 FBD only 1 Exhaust           2  FBE 2 Exhaust

4 Describe the main parts of FBD ?
FBD Parts:
1 lowe plannum
2 Product bowl
3 upper plannum
4 port view
5 lower gasket
6 upper gasket
7 sample port .

5 FBD Howmany sensor in FBD
Inlet sensor Outlet sensor Dew point sensor promixy sensor BBD sensor RH Sensor

6 What is critical process parameter (CPP) in FBD?
Inlet
Product temprature
Exhaust
CFM

7 What is critical process parameter (CPP) in FBE?
Inlet
Exahust
Bed temperature
CFM
RH
Dew point
Atomization Air
Compressed AIR

8 What is BBD?
Broken Bed Detector (BBD) Is work on thermoelectro principle the main motive of BBD is prevent the
product from yiled losses.By mistake finger bag /bonnet bag is broke then BBD alarm pop up in the PLC
.BBD also say SFM sensor Solid flow monitor.
   
9 Why use finger bag in fbd
The finger bag use main motive is to increase the surface area for drying and improve the efficiency of the drying process.

10 What should we do in case of CFM not coming in bowl?
This type of happen case first of all check inlet if inlet are coming so ranking the material because you do not ranking befor drying material are choke in bowl thats reason cfm not come in bowl.

11 What is full form of CFM?
The Full form of CFM is Cubic Per Minute.

12 What is HSG ?
Its mean High Speed Gun (HSG) use in top and bottom spray in FBE.

13 What is role of Atomization Pressure in FBE?
Atomization pressure is used only Spread solution in uniform size .

14 What is dew point?
The Dew point definition is temperature at which air can hold no more water. Below this temperature the water
comes out of the air in the form of drops.

15 What Is RH?
The term of RH is also called a Relative Humidity means How much quantiy Water in present in air this called
Realtive humidity RH.

16 What is limit of lower gasket and upper gasket pressure?
Its limit should do 3.5 kg/cm2 to 4.0 kg/cm2.

17 What is Asynchroneous mode?
Asynchroneous mode used in bottom spray process because during in finger bag shaking air flow and spray
is continue.

18 What is synchroneous mode in FBE.?
Synchroneous mode used in top spray process because during in finger shaking air flow and spray is discontinue.

19 What is size of inner or outer diameter silicon tube ?
the inner diamter is 8mm and outer diameter is 12mm silicon tube.

20 Which Principle work halogen moistrue analayzer
The halogen moistrue are working in thermogravimetric principle.
