What Is a Deodorization Tank? Core Function in Edible Oil Refining & Equipment Advantages

High-quality refined edible oil is characterized by pure taste, transparent color and no peculiar smell. While degumming, deacidification and decolorization remove impurities and pigments, the deodorization tank acts as the core key equipment to eliminate oil odor and upgrade commercial value. It is the final decisive unit that determines the taste, grade and market price of finished oil in the entire refining process.

What Is a Deodorization Tank?

A deodorization tank is a professional pressure and temperature-controlled vessel specially used for removing volatile odor substances in crude oil. It is the core equipment of the fourth stage of the standard oil refining process. Working under high vacuum and low-temperature heating environment, it separates peculiar smell components, free fatty acid volatile substances and oxidative impurities in edible oil and animal fat, realizing pure flavor and stable quality of finished oil.

It is applicable to all types of oil materials, including palm oil, sunflower oil, soybean oil, peanut oil, cottonseed oil, as well as refined beef tallow and mutton tallow. Whether it is small batch refining or large continuous refining production, the deodorization tank directly determines the final food-grade standard of oil products.

Core Functions of Deodorization Tank in Oil Refining

1. Remove peculiar smell and greasy odor

Crude oil produces pungent greasy odor and grassy smell during pressing and storage, while animal oil has inherent fishy and mutton odor. The deodorization tank efficiently volatilizes and eliminates these odor substances through vacuum steam stripping, making the finished oil tasteless and pure, meeting the requirements of direct edible and commercial packaging sales.

2. Improve oil stability and shelf life

Odor substances in crude oil are prone to oxidation and deterioration, which will shorten the oil storage period. Professional deodorization treatment removes oxidative volatile impurities, inhibits oil acidification, and greatly prolongs the shelf life of refined oil, adapting to long-term transportation and market sales.

3. Upgrade oil grade and market value

Only after strict deodorization can crude oil be upgraded from low-grade industrial oil to high-standard food-grade edible oil. Deodorization is the key to distinguish ordinary crude oil from high-value refined oil, which directly improves the profit margin of oil processing enterprises.

Dingsheng Machine’s Deodorization Tank & Refining Equipment Advantages

As a professional manufacturer of full-set oil refining equipment, Dingsheng Machine integrates independent R&D, design and production of core refining equipment including deodorization tanks. We support customized batch and continuous deodorization systems for 1TPH to 1000TPH refining lines, perfectly matching small, medium and large oil plant projects worldwide.

Professional Low-Temperature Deodorization Craft

Different from traditional high-temperature deodorization that damages oil nutrients, our optimized vacuum deodorization technology adopts low-temperature mild treatment. It completely removes peculiar smells without destroying the natural nutrition of edible oil and animal fat, effectively controlling harmful substances and making finished oil quality meet EU and international food safety standards.

Superior Equipment Structure & Durability

Our deodorization tanks are made of high-quality corrosion-resistant stainless steel, with precise vacuum sealing design, uniform heating and full material turnover. The equipment features high deodorization efficiency, no dead angle, stable operation and low failure rate. It solves the common problems of incomplete deodorization, oil oxidation and short service life of ordinary tanks on the market.

Full-process Refining Matching Advantage

Our complete refining production line follows the standard four-stage process of degumming, deacidification, decolorization and deodorization. The self-matched deodorization unit is perfectly compatible with the previous refining processes, with high overall oil yield and low loss. It can be widely used in vegetable oil refining, animal fat refining and waste oil recycling refining projects.
