Dec 02, 2021 An effective method of achieving such separation is through falling film evaporation. FFEs rely on a combination of gravity and evaporation to remove the solvent from cannabinoids and terpenes. The first step is for the solvent and cannabis to be added to the first chamber of the evaporator, called the pre-warmer.

Falling Film Evaporator Design Our falling film evaporator is the simplest and most commonly used type of film evaporator. The liquid flows as a thin film on the inside of heated vertical tubes, driv-en by gravity. The resulting vapor normally flows cocurrently with the liquid, in the centre of the tubes. A full evaporation stage consists of the

Falling film evaporators are vertical shell and tube heat exchangers. Typical TEMA types are BEM, NEN or a combination of the two. The major difference between a typical shell and tube heat exchanger and a falling film evaporator is the liquid distribution at the top of the unit. Liquid entering the top of the unit passes either through a spray ...
