The entire range is available for purchase at the cost-effective prices.
KUMAR CONTINUOUS EXTRACTOR (Direct Drive Type) Supplied with drum shaft, brush shaft and mesh cleaning arrangement.
Horizontal Model comprising of articulated band conveyor assembly, which receives the material from the Feed Hopper and transport, it at a very slow predetermined speed from the feed to the discharge end. The conveyor moves over the rails suitably located inside the Extractor and the rides on specially constructed sprocket at either end, adjustable damper for regulation of the height of the bed of material on the chain conveyor, series of Spray breakers for the perfect spray of the solvent on the moving bed, with liberal provision for light sight glasses. Band Conveyor Assembly designed in such a way to act as filter bed for eliminating fines, complete with rotary brushes & mesh cleaning system for effective cleaning of mesh.
SALIENT FEATURES OF EXTRACTOR
Extractor has single piece Hollow shaft gear box having out put of 0.05 rpm, which is mounted on the extractor main shaft. This is excellence of engineering that avoids the use of Big Gear and pinion arrangement prone to frequent maintenance. Extractor Motor is driven by Variable frequency drive that allows finite adjustment of speed as per processing rates and also allows the data-logging like Run time, stoppage history etc.
Extractor has Single piece miscella hoppers having no joint. This
reduces the welding and chances of leakage during operations.
All body plates and internals are sandblasted and Zink base epoxy
primer coated prior to manufacture. This increase life by reducing
chances of corrosion and increases life of equipment.
Extractor is fabricated in factory, ( site fabrication is
avoided) and running trial is taken in factory to ensure trouble
free running at site.
Prefabrication reduces the time for erection and plant will be
Selection of size - is such that the bed height is limited to 1.5m
which reduces the chances of miscall channelling.
The advantages of low bed height is:
Rate of mark feeding to DT is consistent. Which ensures
consistence vapour flow and control on hexane loss.
Loading of extractor Bed is low, i.e. weight per square m is low
compared to true deep bed extractors which ensures low wear and tear
of band conveyor, ensuring long life.
Additional two hoppers:
Extra miscella hopper at discharge end to allow more hexane to
drain before it is fed to DT, hence load on DT is low ensuring low
steam consumption to evaporate Hexane and low water circulation for
condensation as well.
Extra miscall hopper at feed end to ensure the settling of
miscella before it is transferred to Miscella tank. Major fines are
settled in this hoppers which are then pumped on the top of
The additional miscella spray of this hopper is used to soak the
incoming Flakes so that the regular miscella circulation sprays are
Vapor tight construction in carbon steel, for
de-solventising as well as toasting, specially designed for oilcake and
comprising of a number of stages with bottoms jacketed for the purpose of
indirect heating. Centrally rotating shafts provided with scrappers along
with sparge steam distribution to ensure uniform heating and movements of
the materials in the stages. Fitted with indicators to indicate the level of
material in the stages. Final discharge door is later connected with the
feeding, complete with driving mechanism. With Pneumatic Meal Level
Desolventiser toaster is to be provided with hollow shaft steam
connections to the blades to facilitate injection of steam in the
material through moving blades. This ensures the intimate contact of
steam with meal and effective transfer of latent heat to accelerate
evaporation of hexane. This system ensures the highest contact ratio
between sparge steam and meal to be Desolventised per unit area.
Another advantage of sparge steam through blades is, it reduces the
number of steam injection nozzles and free working space and operator
friendly system, which allows precise controlling of quantity of steam
by one valve.
DT outlet duct is designed to get the vapor velocity sufficient to
cyclonic separation. Wet dust catcher is specially designed with
incorporated cyclone separator and Vapors thoroughly washed with water
sprays for removal of dust particles. This high efficiency cleaning
provides trouble free running of heat exchangers.
The provision of plug-o-seal conveyor with variable speed drive at
outlet of Desolventiser ensures sealing of system. Thus eliminating the
possibility of air entry into the Desolventiser toaster.
DT vapor outlet is routed through various heat exchangers. The
condensers and economizer are so designed to achieve minimum pressure
drop (across shell)
Zero vent system is a unique feature of Kumar system to minimize the
loss of hexane to the atmosphere through final vent. In this system
additional in line steam jet ejector is incorporated to provide pull to
the vapors, which allows the vacuum in DT Vapor outlet duct up to 25mm
of water column. This ensures the effective removal of vapors from DT
without any reflux. Exhaust of final vent steam jet ejector is passed to
extractor through direct contact type condenser and exhausted to
atmosphere through feed bin of extractor. This reduces the amount of
hexane going to atmosphere along with air.
To correctly cook and condition the material prior
to Flaker. Vertical, multi-stage unit with fabricated shell and trays where
heating is carried out by indirect steam. The gates operated by mechanical
level system automatically control the flow of material and the level in
each stage. A central shaft driven by a gearbox carried agitator blades to
ensure a good mix, a homogenous treatment of the material and prevents
burning on the stage bottoms. A vertical duct extracts exhaust vapors from
each stage. Provision is made to adjust final moisture levels of the
material by injecting water or direct steam.
As a Refinery Plant, Vegetable Oil Processing Plant etc.
The suction load data of each steam jet ejector is precisely
calculated which ensures lowest possible consumption of steam, thus
reduction in recurring expenses along with reduction in heat load on
Distillation is carried out in three stages of vacuum. There by
achieving incremental concentration of miscella at predetermined rate.
Further more each stage is differentiated by incorporation of precisely
designed U type siphon pipe, eliminating the use of centrifugal pump.
This ensures continuous flow of miscella, & reduces power
Economizer is specially designed having built in flasher, which
provides the compact design, Minimum plant space and reduction in
unwanted piping. This design itself provides the high efficiency
flashing which increase the miscella concentration up to 75%.
The final stage striping is carried out in presence of steam under
higher vacuum of 700 mmHg. This allows the lower temperature
distillation and theyre by ensuring undamaged crude oil without
