• What is edible oil deodorization?
  • Industrial deodorizers Edible oil deodorization is performed industrially in different ways (continuous, semicontinuous or batchwise) with various configurations of deodorizers (horizontal or vertical vessels, tray-type or packed columns).
  • What is the current trend in edible oil deodorization?
  • In their ¡®historical sketch¡¯ of edible oil deodorization, Lee and King stated in 1937 that the ¡®current trend (in edible oil deodorization) is toward continuous processes with automatic control¡¯ .
  • What are Alfa Laval deodorization systems used for?
  • Alfa Laval deodorization systems are mainly used in the edible oil and animal fat industries, but can also be adapted to for inedible purposes, such as biodiesel and hydrotreated vegetable oil (HVO) pre-treatment. For more information on special product lines from the range of Alfa Laval deodorization/deacidification solutions, see:
  • What is deodorization in edible oil refining?
  • In current edible oil refining, deodorization is also the process in which free (nonesterifed) fatty acids (in the case of physical refining) and volatile contaminants are stripped and unwanted color pigments are degraded (heat bleaching).
  • What is Alfa Laval softcolumn deodorization?
  • This Alfa Laval SoftColumn deodorization installation provides the company with a processing capacity of 1,000 tonnes of palm oil daily. The oil is then held in a retention section for a certain amount of time for thermal treatment ¨C known as heat bleaching ¨C that deals with undesirable pigments and ensures the stability of the final product.
  • What temperature should edible oil be deodorized?
  • Most edible oils are deodorized at high temperature (230-260¡ãC), but there is a growing demand from oil processors to lower the heat load (residence time at higher temperature) during deodorization.
