Later I have made several changes in the design to address most of the issues described above. Some debate, but in polarity, significantly darker byproduct perforated plates and baffles which a! There is series of pumps, called stage pumps, which pump the solvent out of the compartment at one position and discharge it into compartment at the previous position. Hexane is the main component of light gasoline used in the current domestic leaching process. The purer form of extract produced is due to CO2rendering no residual solvent material left behind in the extract, thus requiring no purge of solvent contaminate after the extraction process has completed. The wiper spreads the solids over the plates and pushes the solid through the opening. First I have tried several batch processes, which I am describing below. 11.3.4.3 Bollman extractor It has a vertical orientation and has several perforated baskets attached to a chain conveyor for conveying solids.
