Solid Liquid Extraction (Bonnotto Type) Description and Specifications for Lab Tenders
Solid Liquid Extraction (Bonnotto Type)
The setup consists of Bonnotto type extractor of slotted circular
plates arranged one above the other in opposite radial opening..
The solids are introduced at the top through a hopper spread over the top plate by a rack and pushed to slot to fall to the next plate below and so on to the bottom of the column.
The solvent is introduced near the bottom of the column and it flow upward counter-currently to the solids. A pump supplies the solvent and flow rate is monitored by means of a Rotameter. At the bottom of column a screw conveyor arrangement is done to remove the extracted solids driven by means of an electric motor. Solvent feed tank is kept in a bath fitted with heater and digital temperature controller is used to maintain the constant temperature.
