Deodorizer

Appointment

A deodorizer in the fat and oil industry is a special device designed to remove aromatic substances (odorants) of various types from vegetable oil. Odorants endow vegetable oil with a specific taste and smell. Also, a significant part of free fatty acids is removed from vegetable oil in the deodorizer.

There are several types of deodorizers for oil treatment, including deodorizers with physical and chemical treatment methods. Physical methods include step-by-step deodorization, while chemical methods include more complex processes such as steam treatment and hydrogenation.

Characteristic

• The deodorizer is a metal vertical vessel equipped with a bubbling device and ring coils inside. In case of need for repair or maintenance work, the unit is equipped with a special hatch.
• Deodorizers can operate in two modes: periodic or continuous at high vacuum and a residual pressure of 0.25 – 0.5 kPa, as well as at the design temperature and bubbling of heated steam.
• It is possible to add a continuous or periodic deodorizer (including one already working at the factory) with a thin-film column. Thus, the productivity is doubled without increasing the steam consumption and the load on the vacuum system.
• When choosing a deodorizer for oil treatment, it is necessary to take into account such parameters as performance, size and type of equipment, energy consumption, deodorization efficiency, noise level and maintenance.

The principle of operation

The oil entering the deodorizer through the inlet pipe is heated from the annular coils using heating elements and dead steam. A sharp water vapor is supplied through the bubbler, which saturates the vegetable oil with small bubbles, and then, mixing with odorants, leaves the unit. The final stage of deodorization is the process of cooling the device using cooling coils.

Advantages

• Improves the taste and quality of the oil by removing unwanted odors and flavors;
• Increases the competitiveness of the product and meets the needs of consumers.
