Solvent Extraction Plant

Listing ID #2453936

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

• 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 channeling.
  • The advantages of low bed height is
    
    • Rate of mark feeding to DT is consistent, which ensures consistence vapor 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 these 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.
