Description

Technical Field

[0001] The invention relates to the technical field of oleic acid separation, in particular to a device for producing oleic acid from vegetable oil and an operating method. Background Art

[0002] Oleic acid is a colorless oily liquid with an animal or vegetable oil odor. The color gradually darkens when it is exposed to air for a long time. Industrial products are yellow to red oily liquids with a lard odor. Oleic acid exists in almost all fatty foods and is the most common unsaturated fatty acid component.

[0003] The preparation methods of oleic acid mainly include freeze pressing and crystallization filter pressing. The freeze pressing method first injects the melted fatty acid into a rectangular shallow aluminum tray, cools and solidifies it in a cold room, then takes out the resulting cake from the tray, puts it into a cloth bag, and stacks it on a vertical press. Slowly pressurize it to make the low-melting-point liquid acid flow out, so that the saturated fatty acid and unsaturated fatty acid are separated. The purity (usually expressed by the freezing point) depends on the temperature at which the solid is cooled. The freeze pressing method has low equipment requirements and simple process, but it occupies a large area, has high labor intensity, low efficiency, and cannot be operated continuously. It is suitable for small workshop production, but not suitable for large-scale production in enterprises. Moreover, production enterprises often present dirty, messy and poor phenomena. At present, only a certain amount of oleic acid is produced by this method.

[0004] Therefore, most companies often use the crystallization filter press method to produce oleic acid. The crystallization filter press method is to form crystals and precipitate high melting point hexadecanoic acid and stearic acid by cooling, and then separate them by membrane filter press to effectively separate saturated fatty acids and low melting point unsaturated fatty acids. It is an industrial production method suitable for high-quality oleic acid. The crystallization filter press method is to heat the fatty acid first to ensure that all saturates are completely dissolved, and then send it to a crystallization tank with stirring equipped with a coil or a jacket, and program cooling at a certain stirring speed. Finally, the crystal slurry is sent to a membrane filter press for filtration to obtain an oleic acid product. The crystallization filter press process produces oleic acid, with low production cost, high oleic acid quality, no environmental pollution, and can achieve large-scale industrial production. The disadvantage is that certain process technology control is required, and liquid fatty acids are easily entrained in the hard cake, reducing the product yield. At present, this method is one of the methods widely used and applied to prepare high-purity vegetable oleic acid.

[0005] However, the crystallization efficiency of the crystallization filter press method in the prior art is not high, resulting in low oleic acid production efficiency, and there is room for improvement. Summary of the invention
