When the material turns into a solid after rotary evaporation, the rotary evaporator can no longer rotate even at 40 revolutions per minute. How should this problem be resolved?
Turn it off and on again – the solid remains a solid
To find a solution, one must first be able to describe the problem clearly. It is necessary to properly describe the model of the flow of this equipment and materials. Clogging of solid materials in rotating machinery is not easy to resolve
Control the degree of evaporation; when it’s difficult to rotate or cannot be rotated any longer, remove the solid material and use other drying methods.
Consider a wiped-film evaporator or a falling-film evaporator
