Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of linseed oil processing, and more specifically, the utility model relates to a low-temperature cold pressing device for linseed oil. Background Art
[0002] Flax seeds were brought back to China by Zhang Qian during his mission to the Western Regions in the Han Dynasty in the 2nd century BC and began to be planted in Xinjiang, Gansu, Ningxia, Heilongjiang, Jilin, Inner Mongolia, Shanxi and other places. Flax seeds are one of the five major oil crops in China. Flax seeds have long been mainly used for medicinal purposes and were not used to extract oil until the 16th century. The growth conditions of flax seeds are as follows: a cool climate, fertile soil, and sufficient sunlight, none of which can be lacking. After thousands of years of cultivation by local people, it has been found that the ecological environment with balanced day and night temperature differences, fertile soil, and sufficient sunlight in the northwestern region is most suitable for the cultivation of oil crops such as flax, and it is an industrial pollution-free zone across the country. The flax seeds produced in Xinjiang, western Gansu, and western Inner Mongolia in the northwestern region have an oil content of over 56%. Locals also call it sesame oil. The edible oil pressed out is called "pure oil" in some places in Gansu. It is the designated condiment for the 29th Beijing Olympics, indicating that its nutritional value is internationally recognized. Gansu Province ranks first in both flax seed production and planting area in the country. Qingyang, Pingliang, Dingxi, Longnan, Linxia, Lanzhou and other cities and prefectures are suitable planting areas for flax.
[0003] The existing production processes of vegetable oils are generally divided into the pressing method and the leaching method. The hot pressing method improves the oil yield and taste, and has a strong fragrance, but high-temperature frying of seeds will reduce the content of effective components in the oil and cause protein denaturation. The leaching method has a very high oil yield, low cost, and high economic benefits, but it destroys almost all nutritional components and has trace organic solvent residues.
