Solid Liquid Extraction Bonnoto Manufacturer,Supplier and Exporter in India
Product Code : EL-EELE-11365
Quick Answer: Solid Liquid Extraction Bonnoto is a multi-stage stainless steel column in which solids drop from plate to plate while heated solvent rises against them, with a screw conveyor at the base to carry away the extracted solids.
Last updated: October 2026
Key Features
Circular plates stacked with their openings on opposite sides, so solids pass down stage by stage.
Each stage pairs a plate with a mechanical agitation section.
Hopper feed at the top; motor-driven screw conveyor discharges spent solids at the bottom.
Solvent pumped in near the base, with flow read on a rotameter.
Feed tank in a heated bath with a digital temperature controller.
Stainless steel column, tanks and wetted parts on a painted, stand-alone frame.

About This Product
The unit shows continuous counter-current leaching: solids enter through the hopper, spread over the top plate and are pushed to a slot that drops them onto the plate below, while solvent moves up the column the opposite way. Students set the feed temperature on the digital controller and the solvent rate on the rotameter, then compare the extraction obtained under each condition.
Frequently Asked Questions
How do the solids move through the column?
They are fed through a hopper onto the top plate and pushed to a slot, falling to the next plate and so on down the column. A screw conveyor driven by an electric motor removes the extracted solids at the bottom.
How is the solvent heated and measured?
The solvent feed tank sits in a bath fitted with a heater, and a digital temperature controller sets and shows the feed temperature. A pump delivers the solvent, with the flow read on a rotameter.
What utilities are needed?
A 1 Phase, 220 V AC, 3 kW electric supply, water supply and drain. For trials, about 50 litres of solvent and 30 kg of solid are needed, chosen to suit the system adopted.
