What types of vacuum production systems are used in oil deodorizing?
The chapter discusses the types of vacuum production systems used in oil deodorizing. Deodorizers operate at low pressure to remove unwanted components while at the same time preserving the nutritional value and improving the organoleptic quality of the oil. A dry condensing vacuum system for deodorizers is today considered state of the art.
What is edible oil deodorizing equipment & processes?
Edible oil deodorizing equipment and processes have been developed as a result of advances in hot-pressing and extraction of oil-bearing materials. Early methods included masking of odors by means of aromatics, washing out of odors and neutralization or destruction of odors by means of various chemical treatments.
What are the main vacuum production principles used in oil deodorizing?
Schematic presentation of the main vacuum production principles used in oil deodorizing. Another and maybe more important result is that this dry condensing (DC) principle allows operating deodorizers at much lower pressures, under more cost-efficient conditions (down to 1.0¨C2.0 mbar in the deodorizer vessel).
What are commercial deodorization methods?
Commercial deodorization methods involve steam distillation in vacuo. Processes have been developed independently in several European countries and in the United States. Most efficient equipment uses low absolute pressures and high temperatures in equipment constructed of corrosion-resistant metals and supplied with suitable recording instruments.
