EXPLANATION
Fluid Dynamics & Vapour Compression
- Thermal Vapour Compression in Food Processing:
- Thermal Vapour Compression (TVC) uses a steam ejector (thermocompressor) to entrain and compress low-pressure vapor boiled off from the liquid and recycle it as heating steam.
- TVC is universally employed in energy-efficient Evaporators (multiple-effect evaporators in dairy and juice concentration) to dramatically reduce steam consumption.
- It is not applicable in mechanical homogenizers, pasteurizers, or blanchers.
- Conclusion: TVC is used in (A) only (Option 4).
Correct option: (4) (A) only,
