Description

Vacuum freezing condenser set for edible oil refining

Technical Field

The utility model belongs to the technical field of condensers, and particularly relates to a vacuum freezing condenser set for refining edible oil.

Background

The edible oil is required to be deodorized in the refining step. When the edible oil is subjected to deodorization treatment in the deodorization tower, steam is sprayed into the deodorization tower, the edible oil is fully contacted with the steam under the stirring of the steam, so that the steam is uniformly dispersed in the oil, the odor substances and the substances such as free fatty acid and the like generated in the deodorization tower are pumped into a condenser for cooling by utilizing the difference of the volatilities of the odor substances and the triglyceride in the edible oil under the conditions of high temperature and high vacuum and by means of steam distillation.

At present, many grain and oil manufacturers adopt a dry-condensation mode to cool steam, free fatty acid and other substances generated by a deodorization tower, wherein the dry-condensation mode is to enable the steam, free fatty acid and other substances entering a freezing condenser to be directly frozen into a solid state on a heat transfer surface on a condensation pipe of the freezing condenser without passing through a liquid phase state. When one freezing condenser cools and freezes steam and free fatty acid and other matters extracted from the deodorizing tower, the other freezing condenser removes ice and water, a small amount of non-condensable gas remained in the freezing condenser is pumped by a vacuum pump, and the non-condensable gas pumped by the vacuum pump is almost air.

At present, when the freezing condenser for refining and deodorizing edible oil is used for thawing and deicing frozen ice in the condenser, a mode of introducing steam into a tank body is generally adopted, and a large amount of steam is required to be consumed in the mode, so that a large amount of energy and water resources are wasted, and the production cost of enterprises is increased.
