In most of the vacuum crystalliser, vacuum is generally produced by means of a_____________________?
Correct answer: A. Steam jet ejector with a barometric condenser
- A. Steam jet ejector with a barometric condenser
- B. Compressed air jet
- C. Suction pump
- D. None of these
Explanation
Vacuum crystallisers commonly use a steam-jet ejector, with a barometric condenser to condense the entrained steam and maintain the vacuum. This arrangement is practical for continuous removal of vapour without a mechanical vacuum pump.
