Sunflower Oil Refining Plant Supplied

Spectec techno projects pvt ltd. Manufacturer, supplies, and exports highly energy efficient, customized, cost-effective, turnkey projects for sunflower oil plant/ sunflower oil processing plant with a focus on higher productivity lower operational cost, optimize the use of by-products, and relatively shorter payback period.

Sunflower oil Refining consists of the following Process Steps

Sunflower Oil Refining Plant Process

The crude oil is pumped to the Neutralizer from the storage tank. In Neutralizer the oil is heated up to 60-70 degree C by means of the live and indirect steam provided in to the Neutralizer. The required quantity of Phosphoric acid is slowly added and allow this to react for 30 mins and after that raise, the temperature to 70 degrees centigrade, the required amount of caustic is added to neutralize the free fatty acid. Allow this to react for 10 mins and give a hot water wash, to allow the soap stock to settle. After 4-6 hours, soap stock is drained off. After removing soap stock give a hot water wash to remove the traces of Soap.
The crude sunflower oil is first neutralised by treating alkali with crude oil. Following which centrifugal separators are used to separate soap from oil and then hot water is used to wash the soap separated oil to remove the soap stresses from the oil. Finally drying process is implied to remove moisture from the oil.

Benefits of Double Deck Bleaching Section

  • Oil Earth Mixer is specially designed with higher mixing speed which ensures quick & effective mixing.
  • Continuous Bleacher is a combination of Dry & Wet bleaching which makes it multipurpose.
  • Simple & low maintenance automations.

De-waxing is the process to cool the oil at the temperature, at which wax converts in solid form (actually in slurry form) and the oil remains in liquid form as it is. Waxes and saturated triglycerides which are present in the oil are removed in this process.

Spectec’ s Dewaxing plant is a custom design to allow you to achieve selective crystallization of different triglycerides in edible oil. This is plant you can count on producing stable & filterable crystals giving you the opportunity to produce a product which can fit export quality standards

The process is divided in few steps as given below:

  • Feed oil heating / Heat Exchange.
  • Crystal formation under controlled cooling .
  • Crystal growth .
  • Crystal maturation
  • Filtration

Benefits of Dewaxing Section

  • Low steam & power consumption.
  • Controlled cooling & efficient automation ensures more yield.
  • Special design ensures best crystallization.
  • Simple & Low Maintenance with proper Automations.
  • Space and structure Saving.
Deodorizing is a Distillation process. In which fatty acid is distilled from oil. Under high temperature condition and in presence of high vacuum, with the help of sparging & agitation steam. Further this fatty acid in vapours form, is condensed & recovered in liquid form by the vapour scrubbing system.
Deodorizer is multi-compartment vertical vessel, where each tray are specially designed which Ensures uniform distillation of odoriferous substances. Oil is overflows from tray to tray. Specially designed trays provide sufficient mass transfer surface for effective removal of volatile matters. Flow control system at the outlet of the deodorizer, ensures the maintenance of required level at the bottom tray. The steam used for stripping off volatile matters in the oil is distributed evenly and intensively, the steam meets the deodorized oil. Stripped off the volatile matter and rises through the vacuum. Stripping the volatile matter from the oil. The counter-current flow of steam and oil like this in specially designed trays lower steam consumption, than the conventional deodorizers. The deodorized oil leaving regenerative heat exchanger and finally cooled by water in heat exchanger finally this oil is passed through the alternatively operating set of polishing filters.

Benefits of Deodorizing Section

  • Vacuum balance tray design ensures zero vapour logging i.e. effective distillation.
  • Online fatty spraying also helps for zero vapour logging which ensures maximum vapour to carry to the scrubber without distilling in trays.
  • Effective de-aeration increases the heat exchanging efficiency, because of zero dissolved air.
  • Efficient re-generative heat exchanging trays ensures maximum heat recovery and addition deodorizing time.
  • Counter current flow (oil/steam) design increase the tray efficiency for better deodorization & distillation.
  • Vacuum sealing arrangement for power failure.
  • Simple & low maintenance automations.
The volatile matters consisting of free fatty acid and other odoriferous substances stripped from the deodorizer are led to the vapour scrubber located at the outside of the deodorizing column. In the scrubber, volatile material rises through the bed of pall rings and meets liquid fatty acid sprayed from the top. Vapours are condensed, cooled, and then recalculated to condensed fresh vapours. Excess distillate collected is led to the storage tank, whenever high level reached in storage space below the scrubber. Fatty acid scrubber is specially designed for minimum carryover of fatty materials, to the vacuum system.
