  • How does the refining process of cottonseed oil affect the yield?
  • It was revealed that during the refining process of cottonseed oil an increase in the temperature of the process causes a transfer of additional 2,2% oil into waste. It is shown that the neutralized oil yield increases slightly without drying of hydrated oil, while drying improves the degree of refining.
  • What is cotton seed oil refining process?
  • Cotton Seed Oil Refining Process constitutes of the following process Steps Degumming, Neutralization, Bleaching & Deodorization. Spectec Techno Projects Pvt. Ltd, manufactures, supply and exports customised and highly efficient Cottonseed Oil Refining Plant.
  • Does alkaline refining of cottonseed oil increase yield of neutralized oil?
  • The process of alkaline refining of cottonseed oil is studied and the methods of increasing the yield of neutralized oil are offered. It was revealed that during the refining process of cottonseed oil an increase in the temperature of the process causes a transfer of additional 2,2% oil into waste.
  • Does drying of hydrated oil increase cottonseed oil yield?
  • When the additionally dried hydrated oil was neutralized, the cottonseed oil yield increased by 2,7-3,8%. Without drying of hydrated oil the increase in the refined cottonseed oil yield after preliminary hydration was no more than 0,5-0,9%.
  • How does neutralization affect the yield of cottonseed oil?
  • During the process of neutralization of cottonseed oil, it was determined that an increase in the process temperature causes the transfer into waste of additional 2,2% of neutral oil. During neutralization of additionally dried hydrated oil, the cottonseed oil yield increases by 2,7-3,8%, whereas without drying – by no more than 0,5-0,9%.
  • What is the acid value of cottonseed oil?
  • Cottonseed oil refining was carried out in laboratory. We used crude cottonseed oil having acid value of 10 and 5 mg KOH/g oil. The acid number is a common parameter in the specification of fats and oils. It is defined as the mg of KOH required to neutralize the fatty acids present in 1g of oil [9, 10].
