300TPD to 500TPD Flaxseed Oil Extracting Machine, Flax Seed Oil Extractor Machine, Flax Seed Oil Extraction Machine

Specifications:

Flaxseed oil extraction machine:

1.High oil yield 

2. Improve thequality of crude oil and cake or meal

1. Solvent Extraction section

  Solvent extraction is a kind of advanced oil extracton,adoping organic solvent  extraction method  according to different solubility of  each component . Now it has been widely applied to oil extraction plants .Oil is extracted from pressed cake by contact (soaking or spraying )between solvent and cake ,them mixed oil of oil and solvent will be got .Wet meals is separated out through liquid cyclone and is conveyed to desolventizer with scraper conveyor.

The adventages are as following :

1. high oil yield k,low residual oil rate of meal.

2. low laber intensity 

3. good work environment

4. good meal quality .

2. Desolventizing -toasting section

The meal from extractor contains 25-35% solvent, for recovering solvent and getting better meal, solvent can be toasted by heating ,High material  layer toaster is usually applied to remove solvent from meal as well as dry extracted meal ;DTDCdesolventizer should be used for extracted meal.

3. Evaporation section

Solvent of miscella is vaporized by heating to improve oil concentration of mixed oil ,i,e volatile solvent is separated from nonvolatile.Negative pressure evaporation is better to make sure good extract oil quality. Long-pipe evaporator(also named raising  film evaporator) is widely used  for this section.

4. Steam- stripping section

After twice evaporation and separation ,adopt steam distillation to reduce boiling point  of mixed oil ,so as to remove trace solvent off at lower temperature. Steam -stripping tower is used in this section.

5. Solvent recovery section 

Considering the production safety and cost ,evaporate ,stripped and toasted solvent should be recovered through condensation Tube condensers are widely used in this section.
