Which of the following is used for the concentration of rubber latex ?
Correct answer: B. Agitated film evaporator
- A. Long tube vertical evaporator
- B. Agitated film evaporator
- C. Short tube evaporator
- D. Calandria
Explanation
An agitated film evaporator is suitable for concentrating rubber latex because agitation handles viscous material and the thin film gives short heating residence time. This reduces overheating and damage to the latex.
