Sunflower seeds are an important economic crop for humans. Its main functions are as follows: 1. Food: Sunflower seeds can be used to extract edible oil, and the linoleic acid in it is one of the essential fatty acids for the human body, which is good for health. 2. Animal feed: Sunflower seeds contain high-quality protein and fat, suitable as poultry and livestock feed. 3. Cosmetics: Sunflower oil is rich in vitamin E and can be used for skin care. 4. Industry: Sunflower oil can be used for industrial purposes such as lubricants, paints and cleaning agents. 5. Greening: Sunflower is a beautiful ornamental plant that can be planted in parks, flower beds and other places for greening. For the above reasons, sunflower seeds play an important role in human life. In general, the economic value of sunflower seeds is very high, and it can be said to be a very important crop. Global sunflower seed production is expected to increase by 4.42 million tons to 56.8 million tons in 2023/24, mainly due to increased production in the European Union and increased sunflower seed planting areas by farmers in Russia and Ukraine, with production in the two countries expected to reach 17.5 million tons and 14.5 million tons, respectively. Global sunflower oil consumption is expected to grow by 5.15% to 20.54 million tons in 2023/24, mainly due to increased consumption in China, India and the European Union. Russia's production is expected to reach a record 17.5 million tons. Generally speaking, there are two ways to harvest sunflower seeds: 1. Manual harvesting: This method requires cutting the sunflowers by hand and then hitting the sunflowers with a hammer to remove the sunflower seeds. This process is cumbersome and suitable for small-scale planting. 2. Mechanical harvesting: The sunflowers are harvested by using a sunflower harvester, and then the sunflower seeds are threshed and separated by using equipment such as a sunflower seed thresher. This method is efficient and suitable for large-scale planting. In large companies in the United States, Canada, Russia, Ukraine and other regions, people use large-scale mechanical harvesting for harvesting. Whether it is manual harvesting or mechanical harvesting, it needs to be carried out during the maturity period of sunflowers (usually in summer). Before harvesting, the maturity of the sunflower seeds can be judged based on the dryness of the sunflower seeds. If the sunflower seeds have turned yellow or have begun to droop, they can be harvested. When mechanically harvesting, you should also pay attention to adjusting the equipment to avoid damaging the seed coat of the sunflower seeds and ensure the quality of the sunflower seeds after harvesting. After harvesting the sunflower seeds, there will still be a lot of impurities in them. Before they are pressed for oil or sold on the market, they need to be cleaned and processed. At this time, use the following machines. 5XFS-7.5FC double air screen cleaner , 5QS-5 stone remover and 5XZ-5 specific gravity separator. These machines can remove leaves, flower discs, stones and empty particles from sunflower seeds. After these machines, the sunflower seeds can have a high degree of purity. However, this is not enough for sunflower seeds that need to be sold after being fried in the market. In order to maintain a good appearance, customers need to use a color sorter. Through optical principles, a high-precision camera is used to shoot the sunflower seeds. After computer chip recognition, the particles with poor color are identified, and then removed through the air gun nozzle. The sunflower seeds we buy in the supermarket are basically processed in this way. For sunflower seeds that need to be pressed for oil, they need to be shelled. This requires the use of a sunflower shelling machine. This machine generally includes the following: a sunflower shelling machine and a sunflower shell and kernel separation machine. After passing through this machine, only white sunflower kernels will be left of the sunflower seeds. At this time, you can use the oil press machine to press the oil. Sunflower seed oil is an oil extracted from sunflower seeds by pressing or solvent extraction. Sunflower seed oil is a yellow transparent liquid rich in polyunsaturated fatty acids (linoleic acid, linolenic acid, etc.), and also contains nutrients such as vitamin E, pigments, and carotenoids. Sunflower seed oil has the following characteristics: 1. Antioxidant: The vitamin E rich in sunflower seed oil has a strong antioxidant effect, which can protect cell membranes from oxidative damage and delay the aging process. 2. Lowering cholesterol: Linoleic acid and linolenic acid in sunflower seed oil can lower LDL (low-density lipoprotein) cholesterol levels and prevent atherosclerosis and cardiovascular diseases. 3. Protect the liver: Linoleic acid in sunflower oil can promote liver cell regeneration and protect liver health. 4. Anti-inflammatory effect: Linolenic acid in sunflower oil has significant anti-inflammatory effect and can improve chronic inflammatory state. 5. Promote immunity: Sunflower oil has a high content of vitamin E, which can promote human immunity. Due to its nutritional ingredients and health benefits, sunflower oil is widely used in diet, health products, cosmetics, industrial production and other fields HEBEI BEIBU MACHINERY TECHNOLOGY CO.,LTD can provide a full set of sunflower seed production machines.
