The goal of deodorization is the removal of naturally occurring substances that cause unwanted smell and taste. These volatile substances vaporize at higher temperatures, then condense and stain surrounding surfaces (for example, kitchen walls). Their removal can be done using distillation columns.
The last step of the refining process is the de-acidification of the oil and the removal of remaining volatile substances via vacuum distillation. At first, the oil is heated up in the initial regenerative heat exchanger, and subsequently, it is injected into the vacuum distillation column. Here, the oil undergoes steam stripping at multiple levels; unwanted chemicals are distilled away, condensed and collected in the drainage tank. The purified oil is pumped into the large-area regenerative economizer, where the incoming oil is heated up by the outflowing oil (in a counter-current system) as well as by steam. After deodorization, the oil comes out neutral, without any taste or smell remaining from the source plant.
The company Farmet offers optional accessories that will satisfy even the most demanding customers. However, the most convenient solutions are usually our turnkey deliveries, which are optimized from both the technical and economic perspectives, meet all your requirements and include the automatization of the entire process.
The deodorization technology ensures neutral taste and smell of oil. High temperatures and the distillation process allow achieving zero humidity, less than 0.1 % of free fatty acids (FFA) and a neutral state, such that the oil does not smell or taste of the source plant. Capacities offered range between 24 and 240 tons of oil per day.
