What is oilpress/oil press/oil presses?

Oil Press Category

1. Water Pressure Oil Press
Also known as hydraulic oil press, now has been replaced by spiral oil press. It is a passive system to making oil. The oil yield of single machine is low and covers much area of more equipments. The workshops need to be warm. The operating condition of hydraulic oil press is poor.  But hydraulic pressure oil presses feature with  simple constructure, saving power etc. It can be used in some isolated scattered oilseeds (such as rice bran, wild oilseeds) and some oilseeds which need to maintain the special flavor or nutrition of material (such as cocoa, Olive, sesame etc.). In addition, hydraulic oil presses can also be used for separation of solid-fat bran or wax bran.

2 Spiral oil press
Spiral oil press is most popular equipment to process oil materials now. It features with continuous working for large treatment, dynamic press in a short time, high yield of oil extraction, low labor cost etc.
The essential part of spiral oil press is barrel. Barrel is composed of bar cage and the revolving screw shaft in bar cage.  The working process is to use the reduction of lead of screw in the shaft or gradual increasement of root circle diameter, which caused the volume of barrel smaller and smaller to create pressure of press. The shrinking space have a crushing effect.
The pressing oil from the slot squeeze out of the cage, while residue is pressed into bits like cake, discharging from the end of the shaft of the oil press. To process oil can be divided into three stages that is feeding (preloading), main pressing (oil out), and making cake (high pressure of oil extraction).

The classification of raw oil materials and their characteristics

1, Soybean
Soybean is a high-protein oilseeds with good quality. The oil content is 15.5% -22.7%, with 30% -45% protein. Soybean has become the most important oilseeds in the world. The production of major state-owned is United States, Brazil, Argentina, China, India etc. Soybean is one of the major sources of edible oil, vegetable protein (food and feed) in the world.
Soya bean oil contents unsaturated fatty acid up to 60% or more, with linoleic acid  51.7% and linolenic acid 2% -10%, so soybean oil has a very high nutritional value, but poor in stability.

2. rapeseed
Rapeseed is the only high oil content material can be planted all over the world. Rapeseed is one of the main oil crops and honey source crops in China. The seeds are the main raw materials for oil process. Cultivation of rapeseeds is throughout the country, divided into two kinds, winter rape and spring rape. Its planting area is more than 40% of total oil materials in the nation. Capacity is more than 30% of the total oil capacity, ranking first in the world. The oil content of rapeseeds is  33% -48%.

3. cottonseed
Cottonseed is the seed of cotton, accounting for about 60-62% of cotton grade. The oil content of whole granule of Cottonseed is 15% -25%. The kernels of cotton contents oil of 28% -39%, with 30% -40% protein.

4, peanuts
Originating in South America, peanut is an important high oil Shelled soft oil material. Peanut kernel rate is 65% -75%. The oil content of kernel is 40% -51%, with protein 25% -31%. Peanuts are the most important resources of fat and protein.

5, sunflower
Originating in Mexico, by end-use consumption can be divided into edible sunflower and oil sunflower. The granule of common sunflower is big, with oil content 29-30% and shell 30-40%. The kernel contents oil 40% -65%. Oil sunflower is most small black seeds. The whole seed contents oil as high as 45% -54%,  shell with a low rate of around 22%, protein-containing 21% -31%.
Sunflower oil is a high quality edible oil, known as 'nutritional oil'. It contains more polyunsaturated fatty acids and vitamin E, easily absorbed by the human body. The linoleic acid contents up to 70%, which can reduce cholesterol in the human body. Sunflower oil can be used to produce margarine, mayonnaise and salad oil, and so on.

6, sesame
Sesame is the world's oldest one of the edible oil materials, known as 'Queen of oil seeds'. It features oil content as high as 45% -63%, with protein content of 19-31%. Sesame oil is one of few vegetable edible oil which don't need 'very refined' and can be eaten. It contains 43% of oleic acid and 43% of the linoleic acid, at a higher nutritional value. Due to natural antioxidant phenol of sesame, the chemical properties of  sesame oil is very stable. The oil extracted by Chinese water process with grinder is called small grinding sesame oil which is rich in flavor and have special features.
 
7, rice bran
It is by-products of rice processing. To process 100 kg of brown rice can get 5-8 kg of rice bran. Rice bran contents oil 14% -24%. Rice bran oil as the cereal category 'nutritional oils and fats', have the significantly effectiveness to lower serum cholesterol levels in human body. Because rice bran contains strong lipase activity, easy to make rice bran rancidity degeneration, affecting the quality of oil. Rice bran oil is necessary to pretreat passivation lipase activity.
It is worth noting that in general rice bran contains 3.5% -7% of the rice germ and rice germ itself contents higher oil rate of about 25% -37%, which can use as food separately or as food oil.

8, tea seed oil
Camellia is a special oil material of southern China, which India, Vietnam, Indonesia and other countries have planted, too. Shelled tea seed oil, with 50% -72% kernel, the entire dry oil-bearing seeds content oil 30-40%.  Kernel contents oil 40-60%, protein 8% -9%. Tea seed oil is not dry oil, with a large number of unsaturated fatty acids, which is good medicine, nutrition edible oil.

9, Tung tree seeds
China abounds in the tung trees, which belongs woody oil plant. Tung tree with seed-rate of 51% -71%, 32% of oil-bearing seeds Tong 41.9%, with 20.5% -27.7% protein, 50% of Tong Ren oil -62%. Tung oil in the α-Zaytun acid containing 77% -86%, attribute dry, toxic and can not eat. Tung oil is China's famous specialty, the traditional export products, in a wide range of industrial uses.
10. Sapium seed
Chinese Tallow is our specialty. Sapium seed can be processed after the two oil: Jiu outer layer of oil (also known as the skin oil) and Yan Zi in fat (also known as the Green oil). The two are mixed squeezing the oil-called oil. Jiu seed containing 35% -43% of wax, wax in the Jiu-fat 70% -75%, with rates of 28%--33%, in the oil-58% -62% of the entire oil-bearing seeds about 40% -53%. Jiu Zi fat and oil industries are oil.

11, oil palm fruit
Also known as palm oil palm, a perennial woody palm oil. Oil palm fruits, including fresh fruit meat (dry oil by 45 to 50 percent) and brown-in (dry basis of 48% -55%) in two parts, known as "the world oil Wang," said. Oil palm nut oil is characterized by a two-extraction method, that is, first and then extract oil from the skin in the production of nucleolus-oil. After all the two can be refined for consumption.
Palm-oil containing more than 80 percent of the unsaturated fatty acids, skin oil also contain more than 50 percent of saturated fatty acids, both of which are semi-solid fat, good stability, high smoke point, storage of good and high nutritional value (vitamin E-rich Health-A and sitosterol alcohol and lecithin, etc.). Preparation is brown-cocoa butter, margarine quality raw materials. Liquid palm oil is a good frying oil.
