Problems solved by technology

[0008] Therefore, refining technology has a greater adverse effect on cold-pressed oil. The nutrients retained by cold-pressed oil due to low-temperature operation will be lost in large quantities under conditions such as high temperature, high vacuum, and addition of white clay during the refining process. As a result, cold-pressed oil loses its natural, healthy and nutritious properties, greatly reduces its nutritional value, and loses the characteristics of cold-pressed oil
[0009] In addition, in the process of excessive oil processing, the color becomes lighter and the nutritional content is greatly reduced. Among them, the loss of vitamin E is about 70%, and trans fatty acids harmful to human body will be produced at the same time. It will consume more energy, produce more pollutants, cause waste of raw materials and resources, and increase environmental pollution at the same time.

Embodiment 1

[0037] Such as figure 1 As shown, the refining process of cold-pressed oil in this embodiment includes the following steps: cold-pressed oil→heating process→acid addition process→cooling and crystallization process→adding adsorbent process→filtration process→dehydration process→finished cold-pressed oil.

[0038] Cold-pressed oil: cold-pressed oil of all kinds of oils that can be eaten directly. This process does not include processes such as alkali refining and high-temperature deodorization. It is not suitable to apply this process for refining. For the cold-pressed oil coming out of the cold press, the mechanical impurities in the oil can be filtered first. If there are few oil impurities, it can be directly entered into the next process without filtering. In this example, the cold pressed oil is linseed oil.

[0039] Heating process: Heat the oil to 70°C to 75°C with a heater.

[0040] Acid addition process: It is used to mix and stir the heated oil and acid solution in...

Embodiment 2

[0060] combine Figure 6 As shown, the process steps of this embodiment are basically the same as those of this embodiment, except that the reaction vessel includes a connected first reaction tower 11 and a second reaction tower 12, that is, two towers, while the structure of the tower body is the same as that of the embodiment 1 is the same.

[0061] The first reaction tower 11 has an oil inlet 11a, an acid inlet 11b and an oil outlet 11c, wherein the oil inlet 11a, the acid inlet 11b are located on opposite sides of the bottom of the first reaction tower 11, and the oil outlet 11c is located at the first One side of the top of the reaction tower 11 is located on the same side as the acid addition port 11b.

[0062] The second reaction tower 12 has an oil inlet passage 12a, an oil outlet passage 12b, and a water-adding passage 12c, wherein the oil inlet passage 12a is positioned at the top of the second reaction tower 12, and the oil outlet passage 12b is positioned at the b...

Abstract

The invention relates to a refining process of cold pressed oil. The refining process comprises the following steps: cold pressed oil, heating, acidifying, cooling and crystallizing, and filtering to obtain the finished cold pressed oil. According to the method disclosed by the invention, various cold pressed oil is moderately refined, acid and water are sequentially added, and synchronous stirring is implemented during cooling, so that the treatment time is shortened, the crystallization of the oil is more facilitated, harmful impurities with storage, use and functional characteristics of the oil are more favorably removed, beneficial components such as bioactive components are retained, and the oil quality is improved. And pigments, volatile substances and the like of the cold-pressed oil are not influenced, so that the flavor and the characteristics of the cold-pressed oil are not influenced.

Description

technical field [0001] The invention belongs to the technical field of oil treatment, and in particular relates to a refining process of cold-pressed oil. Background technique [0002] Edible oil is one of the three major sources of nutrition for human beings. The nutritional value or nutritional and health functions of edible oil mainly depend on the fatty acid composition of the oil and the oil-soluble trace components contained in the oil. In the process of preparing oil from oil, there will be The impact on the fatty acids and trace components contained in it will also have a certain impact on the nutritional value of the oil. Therefore, the requirements for the oil production process are not only to increase the oil yield as much as possible and reduce the production cost, but also to try to improve the quality of the oil. , to reduce the damage to various nutrients or functional components in oil. Oil production methods mainly include: pressing method, solvent leachin...
