long tube vertical evaporator cover for wood

Evaporation Plant, Evaporators, Evaporation Evaporators, Long .The long-tube vertical (LTV) rising-film evaporator is commonly used to concentrate many non-salting liquors. For liquors requiring evaporation at extremely low ΔT's, and for critically heat-sensitive liquors, the long-tube vertical (LTV) falling-film evaporator is preferred.

Explanation: Climbing Film Evaporator, in this type the liquid to be evaporated is fed at the lower end of the vertical tubes, heated by the condensing steam on the outside of the tube. The liquid starts boiling at the bottom; the vapor along with the liquid tends to rise further up the tube in the form of a thin film.

1. Climbing film evaporators: Historically, this was the first industrial film evaporator. The liquid is introduced at the lower end of vertical tubes (Fig. 21.19) and quickly reaches its boiling point. The vapor formed moves upwards and drags with it the liquid film which continues to boil and generate more vapor.
