Deodorization

Posted by on 11/2/2016 to Deodorization
Deodorization is the process of minimizing the pungency of the natural odors that are present in edible oils. The process involves high-temperature steam distillation that sucks off the volatile material and other pigments that could possibly affect the product’s flavor.  This leaves only the clean-smelling clear oil that is sold in supermarkets. Before reaching the deodorization stage, the oil must first go through a series of chemical processes:
1.    Deaeration – the process of removing air to prevent oxidation.
2.    Heating – the process of heating the oil in an economizer in order to recover as much of the hot oil’s heat as possible.
Once these processes are done, it is time for the main deodorization process to be completed. The oil goes into a high vacuum chamber with high-pressure steam blowing right below it on high temperature. The final deodorization process that the oil goes through is called heat bleaching, wherein the oil is thermally treated on the retention section for the amount of time needed to achieve the desired flavor and texture.
Some of the end-products that have gone through the process of deodorization are:
  •    Margarine
  •    Vegetable oil
  •    Soybean oil
  •    Coconut or Palm oil
  •    Corn oil
Even nuts and crude oil have gone through simple deodorization processes, albeit in lower pressure and lower temperature vacuums.
Removing offensive odor through deodorization is no longer confined to the end-products of edible oils. There are new technologies that have made it possible for carpets, rugs, and furniture to be de-odorized. Carpet and furniture deodorization agents can actually be hired from the internet. However, homemakers who prefer to do the deed themselves can actually deodorize their carpets with these simple carpet deodorization steps:
1.    Use a vacuum to remove dirt particles and loose carpet fiber.
2.    Sprinkle a generous amount of baking soda onto the newly vacuumed carpet and leave it be for a few hours to make sure that all the offensive odors are sucked off completely.
3.    Vacuum the baking soda off.
One expert advice: to make sure that the deodorization process is worth all the effort, make sure to mix in an essential oil like lavender onto the baking soda before sprinkling it on the carpet. As the baking soda sucks the bad odor off of the carpet, the carpet sucks in the essential oil, giving it a cleaner and more natural scent.
Deodorization facility upgrades are also offered by some manufacturers to oil refinery owners who already have an existing deodorization processing system. Upgrading these systems provide the following benefits:
  •     Boosts the deodorizer’s capacity
  •     Improves the quality of the end-product
  •     Reduces the costs associated with production
An upgrade can be done by attaching separate components to the existing deodorization facility to replace the older ones. The attachable components are the stripper, final heater, the scrubber, and the economizer. By purchasing these separately, the refinery owner is able to cut costs as compared to the old way of replacing the entire deodorization facility when only one or two of its components break down.
