Edible oil is an indispensable food raw material in people’s daily life, and the quality of edible oil directly affects people’s health. In order to improve the quality of edible oil, it needs to be refined. Physical refining is an important part of the edible oil refining process, and physical refining equipment is one of the key equipment to achieve this process.

Generally speaking, physical refining refers to the process of removing impurities from edible oil by physical methods. Physical refining equipment mainly includes deacidification towers, deodorization towers, condensers and other equipment. These equipment processes edible oil through different physical principles, such as distillation, condensation, filtration, etc., to achieve the purpose of removing impurities and improving oil quality.

The deacidification tower is one of the important equipment in the physical refining equipment, and its main role is to remove free fatty acids from edible oil. The deacidification tower uses the principle of distillation to evaporate the free fatty acids in the edible oil at high temperatures, so as to achieve the purpose of removal. At the same time, the deacidification tower can also achieve precise treatment of different types of edible oil by controlling parameters such as temperature and pressure.

In addition to the deacidification tower, the deodorization tower is also one of the indispensable equipment in the physical refining equipment. The deodorization tower mainly removes odorous substances and impurities in edible oil through the principle of condensation, so as to improve the taste and odor of edible oil. At the same time, the deodorization tower can also achieve precise control of volatile components in edible oil through multi-stage condensation and fractionation and other technical means.

In addition, the condenser is also an important part of the physical refining equipment. The condenser mainly uses the cooling principle to re-condense the evaporated free fatty acids and odorous substances into liquids, so as to realize the recovery and reuse of these substances. The design and operating parameters of the condenser have a significant impact on the refining efficiency of edible oil, so it needs to be properly designed and adjusted according to the specific situation.
