In addition to feeding, there is basically no need for other operations, such as automatic temperature control, vacuum filtration, simple operation, small floor area and high oil yield.

Peanut oil is light yellow and transparent, with clear color, fragrant smell and delicious taste. It is a relatively digestible edible oil. Peanut oil contains more than 80% unsaturated fatty acids (including 41.2% oleic acid and 37.6% linoleic acid). In addition, it also contains 19.9% saturated fatty acids such as palmitic acid, stearic acid and arachidic acid, which is easy for human digestion and absorption. According to foreign data, edible peanut oil can decompose cholesterol in the body into bile acid and excrete it out of the body, thus reducing the content of cholesterol in plasma. In addition, peanut oil also contains sterols, wheat germ phenols, phospholipids, vitamin E, choline and other substances beneficial to human body. Regular consumption of peanut oil can prevent skin wrinkling and aging, protect blood vessel wall, prevent thrombosis, and help prevent arteriosclerosis and coronary heart disease. The choline in peanut oil can also improve the memory of human brain and delay the decline of brain function.

Peanut oil press - peanut oil press process:

Cleaning - shelling - frying seeds - pressing - filtering - finished peanut oil

Operating instructions for peanut oil press, screw peanut oil press and small peanut oil press:

(1) Cleaning and drying of peanuts: peanuts entering the oil factory inevitably carry some impurities. If you do not remove the soil, stems and leaves and other sundries carried in the flowers and fruits, they will not only affect the quality of oil and cake, but also absorb some oil and reduce the oil yield. If there are sand, metal, hemp rope and other sundries in the peanut fruit, it will cause the wear of machine parts, cause production accidents and affect the process effect. Therefore, in order to ensure the smooth production of customers, impurities must be removed as much as possible. For individual peanut fruits with high water content, it is also necessary to dry them for the convenience of shelling. There are many methods for cleaning, and different methods can be used according to the situation of impurities. If the impurities contained are light, such as grass, stems and leaves, the method of air separation can be used to blow off the impurities with air flow. If the impurity particles are small, the impurity can be removed by selecting. For some impurities similar in size and relative density to peanuts, if they belong to soil lumps, they can be removed by screening after being rubbed and crushed in the mud machine. If it is a ferrous impurity, it can be separated by electromagnet or magnet. The impurity content shall be below after cleaning.

(2) Shelling: The purpose of peanut shelling before oil extraction is to reduce the adsorption of oil by the shell and improve the oil yield; It can improve the processing capacity of the oil press and reduce the wear of the oil press equipment; It is good for rolling billet and improving the quality of crude oil; It can improve the quality of cake and is conducive to comprehensive utilization.

(3) Heat treatment (steam frying): before frying the seeds, the frying pan should soak the peanut kernels once. During the process of frying the seeds, the kernels should be fried until they are eight mature, kneaded by hand to achieve the separation of kernels and skins. The kernels are light yellow, the temperature is about 130 ℃, the water content is 1-2%, the cake thickness is 0.7-1.2mm, the cake is long and wrinkled, and the oil is smooth. Aoyou Machinery&Equipment Co., Ltd. - customer friend reminded by Aoyou Machinery: the effect of heat treatment has a direct impact on the smooth progress of the whole oil production process, the level of oil yield, and the quality of oil and cake. The heat treatment process is canceled in the cold pressing process, but it needs to be pressed twice. In fact, one press is also a process of heating. The cold pressing oil yield is low and the flavor is much lighter.

(4) Pressing: the peanut oil press produced by Aoyou Machinery Equipment Co., Ltd. - the supplier Aoyou Machinery adjusts the temperature controller to the temperature required for pressing 120 ℃ - 180 ℃ (depending on the oil), turns the heating switch to the heating position of the main machine, and heats the machine. At this time, the green light on the temperature controller is on and the red light is off. When the machine temperature rises to the set temperature, the red light is on and the green light is off, The temperature of the machine is automatically controlled and maintained at the set temperature. When the temperature is low in winter, turn the heating switch to all the heating positions of the main machine to increase the temperature of the oil pan and facilitate the oil retention. There is a certain relationship between pressing time and oil production efficiency. It is generally believed that the peanut oil press has a long pressing time and a slow oil outflow, but the pressing time cannot be too long, otherwise the heat loss will be more, which will affect the oil production efficiency and production capacity. Therefore, on the premise of meeting the oil production efficiency, shorten the pressing time as much as possible. The residence time of the material embryo in the press chamber mainly depends on the rotation speed of the screw shaft, followed by the degree of newness of the screw press ring and the thickness of the cake. For some oilseeds with high oil content, the pressing time can be appropriately extended, and the appropriate rotation speed should be selected.
