Problems solved by technology

However, the existing technology has the following problems: 1) After treatment, the content of colloid and wax in the Eucommia seed oil is still high, which makes it difficult to control the transparency, color and fluidity of the Eucommia seed oil, and also affects the quality of the oil; 2. ) Deacidification adopts chemical reaction to add alkali for neutralization; deodorization is vacuum distillation at -0.008Mpa, 220°C environment, this operation process has low vacuum degree and high temperature; these two steps have a negative impact on the quality of eucommia seed oil had a great impact

Embodiment 1

[0019] The refining process of eucommia seed oil includes washing the crude eucommia seed oil with water, followed by dehydration, degumming, dewaxing, and decolorization. Among them, after decolorization, deacidification and deodorization are carried out at the same time, and finally polishing treatment.

[0020] specific:

[0021] When washing with water, add a NaCl solution with a mass concentration of 0.8%, stir, precipitate, and place it to take the supernatant.

[0022] During dehydration, carry out vacuum distillation under the environment of -0.008MPa and 90°C.

[0023] When degumming, carry out high-speed centrifugation under normal temperature and pressure, and the rotating speed is 14500 rpm.

[0024] During dewaxing, control the vacuum degree to 0.008 MPa, control the stirring at 20 rpm at 2°C, and then filter.

Abstract

The invention belongs to the field of oil refining technology, and particularly relates to a eucommia seed oil refining technology which comprises the following steps of: washing the crude eucommia seed oil; dehydrating and decoloring; performing deacidification and deodorization at the same time after the decoloring; and finally performing polishing treatment. According to the invention, deacidification and deodorization are performed at the same time, and physical operation is adopted to avoid chemical reaction and high-temperature operation, thereby greatly improving the oil quality.

Description

technical field [0001] The invention belongs to the technical field of oil product refining, and in particular relates to a refining process of Eucommia ulmoides seed oil. Background technique [0002] Eucommia ulmoides seed oil is mainly composed of unsaturated fatty acids, of which α-linolenic acid content reaches 60%. α-linolenic acid acts on the human body to lower blood fat, regulate blood pressure, and improve sleep. Since unsaturated fatty acids are easily oxidized at high temperature for a long time, the refining of eucommia seed oil must control the temperature, time and vacuum degree. At present, the refining process of eucommia seed oil crude oil is basically as follows: the eucommia seed oil crude oil is washed with water, followed by dehydration, decolorization, deacidification, deodorization, and finally polishing. However, the existing technology has the following problems: 1) After treatment, the colloid and wax content in the Eucommia seed oil is still high...
