Continuous deodorizing for oils and fats
Achieve optimal purity and flavor in oils and fats with advanced continuous deodorizing, ensuring unwanted odors and free fatty acids are effectively removed for superior end-product quality.

The Double Shell Continuous Deodorizer from Crown Iron Works is engineered for seamless integration into oil refining operations. It utilizes a packed column design to effectively deodorize and de-acidify oils and fats, essential for producing quality edible oils, biodiesel, and nutraceutical ingredients like tocopherols and omega-3 supplements. With its unique double shell configuration, it minimizes air infiltration, optimizing vacuum retention and ensuring efficient stripping of free fatty acids. Equipped with high-efficiency vacuum systems and distillate scrubbers, it enhances energy efficiency while preserving product quality. This system supports both continuous and semi-continuous operations, catering to diverse production needs across industries like pharmaceuticals, specialty chemicals, and food processing. Constructed with corrosion-resistant materials, it offers robust durability. The design facilitates easy maintenance, with external heat exchangers and hermetic sealed pumps ensuring minimal downtime and consistent production throughput.
