PIGNAT Continous Solid Liquid Extraction – ESC2000


SKU: ESC2000 Category: Tags: ,


Continuous solid-liquid extraction of plant extracts with water

Study a continuous solid-liquid extraction process :
Three extraction stages in series operating in counter-current
Concept of residence time in each extraction stage
Materials balance on the solute

Define operating parameters:
Initial solute concentration of solvent and inert solid
Temperature (max. 50́C)
Flow rate of solid and solvent

Define the yield of a continuous process :
Overall yield, yield of each stage
Observe the transfer stages
