Durable and effective Falling Film Evaporator is available for meeting the needs of products having low viscosity. This is developed with tube bundle and liquid distribution device for ensuring uniform distribution of the liquid. It ensures low temperature difference as well as high heat transfer coefficients. This Falling Film Evaporator ensures short product contact time for reducing thermal degradation effects. In addition, this is available with high vapor shears for misnaming the foaming products. Low tube wall temperature also reduces fouling.
