Product Description

Solvent Extraction:

 
Preparation:
 
 
SEED CLEANING
Seeds are properly cleaned into seed cleaner to remove unwanted material like dust, leafs, steins etc. Then the seed is subjected to Destoner to remove various sizes of stones / sand. This removal of unwanted material increases the life of machines & reduces the down time.
 
CRACKER
Four roll Cracker to break the seed into quarter and eight sized pieces comprising of Carbon steel frame, cast alloy rolls Double strand. Rolls Two (2) V- belts drive motor & Diverter gate. Hinge-Mounted Permanent magnet.
 
CONDITIONING / COOKING
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.
 
FLAKER
Most seeds have tough oil bearing cellular structure which has to be ruptured or weakened prior to cooking and extraction. Flakers are normally used to increase the capacity of Expeller as well it reduces the wear & tear of the Expeller machines
 
EXPANDER
Expander is mainly used to prepared collets from soya flakes. Collets increase the porosity which in turn increase percolation of hexane this yields faster extraction of oil from collets.
 
HULLER SHAKER
Huller Shaker is a machine where kernel is separated from the seed & the hulls are separated from the kernel. In this process, one can increase the capacity of the machine by doing de-hulling as well decrease the down time of the machine. This process is mainly used in case of Cotton Seed / Sunflower.
 
HULL & SEED SEPARATOR
In this process the hulls are separated from the seeds & unbroken seeds are again subjected to Huller Shaker. It is used for minimum oil absorption and best separation of hulls from large meats and uncut seeds. This process is mainly used in case of Cotton Seed / Sunflower.
 
DOUBLE DRUM HULL BEATER
Double Drum Hull Beater is used to separate the kernel portion to hulls. This reduces the wastage of kernel going with hulls.
 
HAMMER MILL
Hammer Mill is mainly used to disintegrate the product to desired size to have the proper Expelling. The Hammers (Beaters) are rectangular for efficient grinding & are made from hardened alloy steel. Hammer Mill is mainly used in case of Copra, Palm Kernel & Soya bean processing.

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
  • Drive -
  • 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.
  • Construction -
    • 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 started quickly.
    • 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 extractor.
      • The additional miscella spray of this hopper is used to soak the incoming Flakes so that the regular miscella circulation sprays are used effectively.
   
     
DESOLVENTISING TOASTING:

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 Controlling arrangement.
SALIENT FEATURES:
  • 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.
   
     
DISTILLATION
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.
SALIENT FEATURES
  • 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 condensation system.
  • 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 consumption.
  • 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 they’re by ensuring undamaged crude oil without color fixation.
