Question

What is the principle of homogenisers?

• A. Passing the fluid through restricted orifice under high pressure
• B. Centrifugal force caused between rotor and stator
• C. Attrition
• D. Sonic pressure

Hint:

Think of a pressure washer: forcing liquid through a tiny hole breaks it into a fine mist.

Answer 1

The Correct Option is A

Step 1: Concept
Homogenization is the process of reducing droplet size in emulsions to create a uniform, stable mixture.

Step 2: Meaning
A homogenizer forces the coarse emulsion through a very narrow gap or orifice.

Step 3: Analysis
When the fluid passes through the restricted orifice at high pressure, it experiences intense shear, turbulence, and cavitation. This breaks large globules into extremely fine ones (often sub-micron size).

Step 4: Conclusion
The working principle relies on forcing the fluid through a restricted orifice under high pressure.

Final Answer: (A)
