by Ernestburns on September 09, 2022
Original Title: Difference between Short-path Distillation and Molecular
Distillation-Shanghai DEA Short-path distillation, "short path" refers to a
shorter distance, in a broad sense, the evaporator adopts the design scheme that
the distance from the evaporation surface to the condensation surface is less
than 300 MM, which can be called a short-path distiller. In terms of design
structure, it can be divided into scraper short-path distiller, centrifugal
short-path distiller and short-path distillers evolved from the condenser
installation position of film evaporator improved by some manufacturers in ...
