Forced circulation evaporator manufacturers suppliers .

Forced circulation evaporators are tubular heat exchangers for concentrating a feed. Three factors are to be considered when designing a forced circulation evaporator: liquid-steam seperation, exchange of heat, and energy-efficiency.

Evaporators and condensers in a new dimension

The AlfaFlash is a plate evaporator, working as a forced circulation flash evaporator, often used in the final concentration step as a finisher. It is designed with a high wall shear to minimize viscosity (in case of a shear thinning product), fouling and to maximize time intervals between cleaning. The considerably higher shear rate
