Rapeseed oil press is mostly used in rapeseed oil pressing, this equipment is commonly known as screw automatic oil press. The spiral rapeseed oil press is mainly divided into two parts: hydraulic pressure and pressing cavity.Rapeseed oil press is mostly used in rapeseed oil pressing, this equipment is commonly known as screw automatic oil press.
1. Hot pressing: cleaning the rapeseed-softening the-steaming and frying-squeezing operation instructions: the rapeseed is selected with a 30 mesh/inch screen to make the rapeseed less than 0.5% of impurities, and then proceed After softening, the rapeseed has a moisture content of about 9%, then rollss, steams and stirs, and steams and stirs to make the oil temperature reach 110-120 degrees, and its moisture content is about l-1.5%, then it can enter the oil press Squeeze. If you use a cylindrical frying pan, the rapeseed can directly enter the cylindrical frying pan after cleaning and removing impurities, or enter the flat-bottom frying pan after rolling the.
But add 2-3% water when frying the seeds, and when the temperature reaches 110-120 degrees, it can be pressed out of the pot. When hot pressing, the following methods can be used to judge whether the rapeseed is fried well. Rub the rapeseed with two wooden boards. If the shell and kernel are separated, the kernel becomes dark yellow. If the kernel becomes powder, it is too dry, and if the shell and kernel are not separated, it is too wet.
2. Cold pressing: Rapeseed can also be cold pressed. During cold pressing, the rapeseed can be cleaned to remove impurities. You can add l-12% water to soften the rapeseed. After softening, the can be rolled. It can also enter the oil press without rolling the. For pressing, (but pressing after the rolling can improve the performance of the oil press) during cold pressing, the moisture content of the rapeseed will directly affect the oil output efficiency, so it is very important to judge the dryness and wetness of the oil, generally before pressing Control the moisture content of rapeseed at 5-8%. Use the soil method to judge the moisture content of rapeseed. You can squeeze the rapeseed with your nails. If it makes a noise, divide it into two pieces. The powder package has less moisture and too dry, if it is flat, the moisture content is high and too wet.
1.Electricity saving: the electric power can be reduced by 40% in the same output. In details, the machine can save 6 kws/h a day that is worth about 30 $.
2.Labor Saving: 60% labor force can be saved for equal output. Ony one or two persons are needed for the production, which can save about 40 RMB/day.
3.Wide application: more than 20 kinds of oil crops can be pressed by this machine,such as, peanuts, sesame, vegetable seeds, soybean, sunflower, cottonseeds, flax, etc.
4.Oil Purity control: the vaccum oil filter is used to remove the residues in order to ensure the oil quality which can meet the health and sanitary regulation.
5.Less ocuppied area: only needs 10 ~ 20m2 for production.
6.The oil left in cakes is less than 6%. The cake thickness can be adjusted when the machine out of work, and the cakes also can be used for animal feed
Rapeseed is the only oil plant with high oil content that can be cultivated all over the world. It is one of the main oil crops and nectar crops in my country. Its seed is one of the main varieties of oil for soaking. The oil content is 35%-50%. The human body absorbs rapeseed oil. The rate is very high, up to 99%. Therefore, it contains unsaturated fatty acids such as linoleic acid and nutrients such as vitamin E can be well absorbed by the body, and has a certain effect of softening blood vessels and delaying aging.
