Thanks to this most modern and versatile design of
expanders which can be very well adopted in the preparatory section itself.
MUEZ-HEST continuous solvent extraction plant thus completely eliminates the
dependency on Oil Mill Plants during lean seasons and gives additional
advantage to solvent extraction plant owners by direct extraction from high
oil content seeds.
The prepared material from Preparatory section is
received in the Feed Hopper through Rotary Valve/Plug Conveyor. The material
in the hopper and the rotary valve/Plug Conveyor together constitute an
effective vapour seal while the latter also serves to regulate the feed. The
hopper is further provided with the special switches for high level and low
level indications. The latter if energized stops the band conveyor of
extractor while the high level indication, transmits an audio visual signal
to Preparatory Section for preparatory operator to take corrective measures.
The MUEZ-HEST Extractor is long horizontal vessel, Rectangular in cross
section in M.S. Construction. An articulated band conveyor inside the
Extractor receives the material from Feed Hopper and transports it at a pre
determined speed from the feed end to discharge end. The band conveyor moves
over rails suitably located inside the Extractor and rides on specially
constructed sprockets at either end. The speed of the band conveyor is
easily adjustable within desired limits. An adjustable damper enables the
regulation of height of bed of material on band conveyor.
A series of sprayers located above the band conveyor enable perfect spray
of the solvent on the moving bed. Special spray breakers facilitate uniform
distribution of solvent over the entire width of moving bed. Each spraying
section is followed by a draining section.Fresh solvent is admitted into the
Extractor near the discharge end of the moving bed of material and the full
miscella is recovered from the initial stage; thus ensuring the perfect
counter current flow of material and the solvent.
It is not merely a simple counter current flow. The miscella circulates in
a closed circuit in each of the successive section by overflowing from each
hopper of the Extractor after increasing gradually its oil content in each
hopper. So in each section there is an equilibrium between the oil extracted
from the seed in corresponding section and the difference in oil content of
solvent overflowing the preceding hopper together with the solvent
overflowing the following section.
The cleaning of the band conveyors is accomplished by high pressure jet
spray of fresh solvent onto the return of band conveyor at discharge end
which ensures perfect cleaning of mesh and eliminates completely the
possibilities of choking of mesh and channeling.
MUEZ-HEST offers complete solvent extraction systems featuring:
- Long Extraction Time Ensuring Low Residual Oil.
- Simple, rugged design for low maintenance & reliable
- Easy to transport and install.
