Pecan belongs to the Juglans family, is the world's dried and woody oil tree species, China's native pecans are also known as small walnuts, small walnuts, mainly grow in the mountainous areas with superior climate, fertile soil and lush vegetation, and the distribution area is narrow.
Pecan kernel is rich in nutrition, containing protein, vitamin A, B, C, E, K, carotene, riboflavin, niacin and cover, phosphorus, iron and other trace elements, as soon as the country comes, the health care function of walnut is known and promoted, is a traditional therapeutic product, in modern times, often used to process into a variety of food, nutritional products, etc., nutritional and medicinal value is extremely high.
Pecan oil is extracted from pecan fruit, and the oil content of pecan kernel is about 50%, which is an oil with high oil content. Its commonly used processing methods include pressing method, water agent method, supercritical extraction method and leaching method, etc., and the current industrial production mainly adopts pressing method and leaching method to produce, and the process is mature. At present, pecan oil is favored in the international market, can be used as medicinal oil and advanced edible health oil, has been widely recognized in European and American countries, and has broad market prospects.
The pecan oil processing production line purchased by the oil mill is mainly based on the pressing production line, which is to process pecan oil using the principle of physical extrusion, and there is no addition in the production process, which retains the nutrition and flavor of walnut oil, and is more in line with the nutritional and health needs of mass consumers. In the pressing process, the cold pressing process can better extract the nutritional value of pecans. The nutrition of the oil extracted by the hot pressing process is slightly inferior to that of the cold pressed oil, but the hot pressing process has a series of advantages such as simple operation, high oil yield and rich flavor.
The leaching of walnut oil is usually pre-pressed and then leached, and the pre-pressed cake is used as raw material, crushed, steamed and fried and other processes before being sent to the leaching equipment to leach the residual oil in the cake. The pre-crushing leaching process has a large processing capacity, high efficiency, high degree of automation, high oil yield, and of course, the investment capital and maintenance cost of the equipment are also high, so the output of the oil mill has certain requirements, which is suitable for the oil mill with a daily processing capacity of more than 30 tons.
Regardless of the process, it is important to choose the right production line for your needs.
