Oil Pressing

 
Oil & Fat are the main nutritional components of human food and important raw material of food processing. Oil Processing is one of the important industries throughout the world. Some vegetable oil, including non-edible oil, is also common raw material for other industries. With the rapid development of economy and the continuous improvement of people’s living standard, per capita demand for oil and fat is obviously growing. And the demand for oil quality and nutrition also improve constantly. All these facts make oil processing a very promising and profitable industry to invest in, pointing out the development direction of edible and cooking oil market.

  Promising Oil Processing Market (Vegetable Oil & Fish Oil)

Vegetable oil and animal oil are the two main produces of oil expelling and extracting. Referring to vegetable oils, there are a lot of oil materials, including peanut seeds (groundnut kernel), sunflower seeds, cottonseeds, copra, palm oil, palm kernel, olive, maize germ, soybean, coconut, rapeseed, sesame, grape seeds, rice bran, avocado and so on. Referring to animal oil, fish oil is what we want to highlight.
fish oil

Fish Oil Processing

Fish oil is got from all kinds of fish, such as mackerel, tuna, salmon, sturgeon, anchovies, sardines (sardonios), herring and trout etc. It includes body oil and liver oil. Fish oil has very high nutrition value and health care effect. It is called “liquid gold”. Fish oil processing is a very promising industry. Fish oil extraction includes expression method (expelling) and weak alkaline hydrolysis, solvent extraction, cooking method, enzymatic hydrolysis and supercritical fluid extraction. The purpose of fish oil extraction process lies in increasing fish oil extraction yield and reducing impurity pollution to the environment.
peanut oil

Peanut Oil Pressing

The kernel content of peanut (groundnut) is 68%~72%. The kernel is covered with a 0.3~0.5mm red seed coat. Peanut kernel belongs to high oil content, soft oil material. The oil content is 40%~ 51% and the protein content is 25%~31%. Peanut is one of the most important materials of vegetable oil processing.

 

Sunflower Seed soil

Sunflower Seeds Oil Production

There are mainly two kinds of sunflower: ordinary sunflower and oil sunflower. The oil content of oil sunflower seeds can reach 45%~54% and its hull content can be as low as 22%. This is why oil sunflower a best kind of material for oil expeller pressing. The oil content of ordinary sunflower seed is relatively lower. Besides, sunflower kernels also contain 21%~ 31% of proteins.
Cottonseeds oil

Cottonseeds Oil Extraction

Cottonseeds refer to the seeds of cotton. The hull content is 40~55%. The oil content of whole seeds with hull is 15%~25%. The oil content of cottonseed kernel is 28%~395. Protein content is about 30%. The shell contains very few oil, which can be ignored. Cottonseeds kernel contains 8%~12% of gossypol which is a kind of light toxic substance, and it will mix in the oil when extracting and making the oil inedible. But refinery process can remove gossypol impurities and making it safe and healthy for people to eat.

coconut oil

Coconut Oil Making

Coconut tree is mainly distributed in Asia, islands in the Pacific, Africa, Central and southern America. Generally, the fresh coconut meat will be dried into copra. Coconut oil is extracted from copra. Fresh coconut meal contains 30%~40% of oil and 50% of water, while after drying, the copra contains 60~70% of oil and 4%~7% of water. Coconut oil has special flavor. The coconut oil production in word reaches 3.31 million tons in the year 2000. The Philippines is the world’s largest supplier of coconut oil, followed by Indonesia, Malaysia, and Papua New, Guinea.
palm oil

Palm Oil & Palm Kernel Oil Production

Oil palm is an important tropical oil crop. It has the shape of coconut. It comes from West Africa. It has grown quietly in the tropical rainforest for more than 100 years, until has been found and paid attention to. Nowadays, it is a star of the world’s “Green Oil Depot” and becomes a ready source of money in oil industry. Palm fruit can be divided into fruit meat and palm nut. There is kernel inside the palm nut, called oil palm kernel. Oil palm is regarded as the kind of the world’s oil. Bothe the fruit meat and the kernel can be used as raw material for oil production. For the oil palm fruit, the oil content is 50%~60%, the oil is called palm oil. For palm kernel, the oil content is 50%~55%, the oil is called palm kernel oil. Both these two kinds of oil are edible after refining.
Maize Germ oil

Maize Germ Oil Extracting

Corn/maize germ oil is extracted (expelling or solvent extracting) from corn germ (maize germ). It is rich in vitamin E and unsaturated fatty acid which are both necessary for human body and do good for heart and cerebral vessels. The oil content of dry grinding corn germ is generally 18~23%. The oil content of wet milling corn germ can reach 52%. Maize germ oil is seen as advanced and widely used cooking oil in the European and American countries.
soybean oil

Soybean Oil Expelling

Soybean is also named as soya. The oil content of soybean is 16%~24%, and the protein content is 30%~50%. Soybean is premium in both oil and protein content. It is one of the important resources of edible vegetable oil. Referring to soybean processing, the common method is getting the crude oil with impurities through expelling or solvent extracting, and then after refining process, getting edible soybean refined oil.

Rapeseed oil

Rapeseed Oil Processing

Rapeseed is round in shape. The average diameter is 1~3mm. The color varies from different origin, such as yellow, palm red and brown. Rapeseed contains 33%~48% of oil and 20%~30% of protein. Oilseed rape is a kind of high oil-bearing crops, widely planted around the world. In recent years, canola oil processed from low erucic acid and glucosinolate rapeseed is getting more and more popular.

Sesame oil

Sesame Oil Mill

Sesame seed is flat oval in shape. The seed has several kinds of color, including white, yellow, brown and black. The oil content is 45%~63%. The protein content is 19%~31%. White sesame seeds have the highest oil content, while black sesame seeds have the minimum oil content. During the sesame oil milling process, sesamol is produced, giving the sesameseed oil a kind of special fragrance.

Grape Seed soil

Grape Seeds Oil Extraction (Grapestone, Grape Pip)

Grape seeds oil is extracted from grapestone through cold pressing and oil refining. The color is beautiful and natural light yellow or light green. The oil content of grapestone is 12%~17%. Grape seed oil contains no cholesterol and sodium, can regulate blood lipids. The unsaturated fattyacid content accounts for 90% of total fatty acid content. It is also rich in fat-soluble vitamins. A tablespoon of grape seed oil is equivalent to one day’s need of vitamin E.

Rice Bran  oil

Rice Bran Oil Manufacturer

Rice bran is the main by-product of rice production. Its oil content is 14%~24%. Rice bran oil is a common kind of heath edible oil rich in nutrition. It is also raw materials of tocopherol, oryzanol medicine industry. Rice bran oil processing actually has a very good development prospect.

make oil from castor beans

Castor Oil Manufacturer

A crude castor oil has a pale straw color; however, it turns slightly yellowish or colorless after bleaching and refining. Ricinus Communis grows naturally in different geographical areas and usually activate under various climatic and physical regimes.
