There are many peanut oil press. But here is versatility spiral peanut oil press is the most advanced kind. Peanut spiral hydraulic press divided into two parts and squeezed cavity. Its work is done by high pressure in the peanut oil squeezed. Then after vacuum filtration. After the oil out relatively clean. By mechanical screw press peanut oil crops under high pressure grease partially out. Thus play a crushing purposes. Most are hot-pressed oil extraction. One benefit analysis in order to extract a small machine-pressed 500 kg per day of crude oil (97% yield) as an example: a comprehensive total cost of 6778 yuan of which: 毛油成 this: 515 kg x13 yuan / kg = 6695 yuan; electricity : 25 yuan / 500 kg; artificial one person: 50 / day; Additives: 8 yuan / 500 kg 2, output: 500 kg x16 yuan / kg = 8000 yuan 3, profit = 7500 yuan -6778 yuan = 722 yuan that day profitable 1222 yuan. Second, the small-scale oil refining pot 500 kg per day (98% yield) as an example: a comprehensive total cost of 3141 yuan of which: hot oil costs 510 kg x6 yuan / kg = 3060 yuan electricity: 25 yuan / 500 kg Labor: 50 yuan / person day x1 = 50 yuan Additives: 6 yuan / 500 kg 2, output: 500 kg x10 yuan = 5000 yuan 3, profit: 5000-3141 = 1859 yuan 1859 yuan profit that daily peanut oil extraction Note the use of the machine first: When using peanut oil press oil pump pressure must filtering process, and requires its concentration can not be too large. In the choice of oil, you can not select an unstable oil such as gasoline, oil extraction is generally best if the use of soybean oil and peanut oil and other edible oils. Second: peanut oil press of the tank must be kept clean, to be able to clean the tank regularly, but also to change the oil, make sure the tank is no clogging impurities tank piping, if the oil is blocked, it is easy to peanut oil press work efficiency. Third: peanut oil press at the time of prolonged use, must use the lubricating oil for lubrication, thus reducing the wear of the various parts to each other, in particular the handle with the pin connected to the oil pump.
