Cottonseed Oil Manufacturing Steps

First of all we will put on some useful information about cottonseed and cotton seed oil, I think it is very useful, hope this information can help you get a deeper understanding of cottonseed oil manufacturing process. Cottonseed oil is cooking oil extracted from the seeds of different species of cotton. Cotton is considered as one of the big four oil crops all over the world under soybean, corn and rapeseed. Once processed, cottonseed oil has a mild flavor and appears generally clear and light golden, the quantity of color depends on quality of refining. Cottonseed oil is of high smoke point for frying medium. Cottonseed oil smoke temperature of about 232 °C just as other long chain fatty acid oils. Tocopherols content in cottonseed oil is high, its stability also contributed to the product contains long life, so manufacturers with proclivity of the packed goods.

Actually, the cotton seed oil mill machinery process includes several procedures. First of all, the cotton seed will be sent into shaker room for cleaning, the clean cotton is sent to the grinding room to remove the linter from the cotton seed. Next cotton seeds will be sent through hullers, where the tough seed hull is removed. Seeds acquire the shattered part of this is the kernel containing more oil such as urgently needs to be part of the oil recovery. The cake is included in the oil pressing plant through the solvent extraction. So get oil washing and refined in order to get the edible cottonseed oil. All of these process seamless integration for a smooth operation.

 

Fried the seeds evenly, fire cannot be too high, lest the shell easily burned. Stir the cottonseed after grilled with the rod, make the hot steam cold and clean them by the sieve. Use artificial screen or fixed screen to eliminate impurities. Add water along the grinding roller ring groove, a turn seed, make the billet draft evenly, grinding consistent, run for about 20 minutes until the thin slab does not block. When put the powder into steam barrel, flat it to make steamed barrel breathable even, the temperature and moisture should be consistent.

Steam barrel bottom should be round as back form, in order to heat evenly, steam pan water level consistent, and steamed barrel bottom and the water surface distance from the 16 centimeters of above advisable, burning to divide evenly. Operator should master scattered packet cake, fast to packaging flat tight, concentrated and fast. The bread after squeezing is about 2 cm thick or so, should try to shorten the time, prevent heat loss. At the beginning when the bread is on, adjust the circle and the distance of the circle, lest bread play unevenly. If the oil line breaks down then squeeze for 2 hours before the loose. Oil squeezing out contains many impurities. Should cool it, and lay it up for a long time before filter, in case the color and luster is deepening, increase refining losses.

We Like Sunflower Seed

Sunflowers means to pursue the happiness you want bravely and silent love, it is representative of bright, proud, loyalty and love. The sunflower is widely used, its seed is edible and can be used as raw material of oil pressing, its leaf is edible for livestock, etc. It has a strong connect with our life. It is said that the famous painter Van Gogh found his life enthusiasm in that bright enthusiastic color of sunflower and his sunflower is not only plants, but living organisms with primitive impulse and enthusiasm.

Sunflower seed, that is the fruit of sunflower, it is edible and useful. Sunflower seeds become a carefree snacks very welcomed by the people and cooking oil sourceare for it is rich in unsaturated fatty acid, contains a variety of vitamins and trace elements, plus it tastes delicious. It can be divided into three kinds: For oil use, small seed, thin skin shell, high kernel ratio, about 65%-75%, oil content can be 45%-60%, peel for black or gray stripes, adaptable to extract oil; For eating, bigger seed, thick skin shell, low kernel ratio, about 50% or so, oil content is commonly 40%-50%, peel for more white in black, can be used as fried food or feed;For eating and oil press use both, this type is between the other two types.



Sunflower seed in the people's life is an indispensable snack. Eating sunflower seeds while chatting or watching television, what a leisurely. Sunflower seeds can not only as a snack, but also can be used as the raw material of making cakes. Sunflower seed oil is the high-grade healthy nutrition oil praised by the academic circles in last few years for sunflower seed is the seeds of plants, contains a lot of fat, so sunflower seeds are important oil screw press.

Linoleic acid content is up to 70%, which helps reduce the human blood cholesterol level and is beneficial to protection cardiovascular health, the fat sunflower seeds contain can reach up to about 50%, which mainly for not saturated fat, and does not contain the cholesterol. Rich in iron, zinc, potassium, magnesium and trace elements make sunflower seeds has the prevention of diseases such as anemia. Sunflower seed is a good source of vitamin B1 and vitamin E. People say that eat a handful sunflower seeds can satisfy the human body for a day of vitamin E.

To stable mood, prevent cell aging, adult disease prevention is good. It also has effect of treating insomnia and enhancing memory. Have certain preventive effect on cancer, high blood pressure and neurasthenia. Sunflower seed also contains a variety of vitamins, folic acid, iron, potassium, zinc and other human body essential nutrients in addition to the rich unsaturated fatty acid. Sunflower seeds contain a large number of dietary fibers, every 7g of sunflower seeds contains 1g. The content of iron also can prevent the occurrence of anemia the American cancer research relevant experiments have proved that dietary fiber can reduce the incidence of colorectal cancer.

Small Scale Peanut Oil Production Unit

We always hear about the peanut oil press machine, it is very close to our life. Groundnut is just another name of peanut and peanut oil is the most popular cooking oil in the world. You may be considering of running your own peanut oil production scale small unit to individual peanut oil daily use or make money in your country, this is the very place to start with if this is what you want to do. Many people want to buy but they are afraid of buying defective goods, now we are going to see the structure and performance of peanut oil press machine, the most headaches thing of people who want to buy peanut oil press is the unknown knowledge of oil press performance and structure.

It is easy to understand the structure and performance of peanut oil presses. Small scale groundnut oil production unit contains peanut sheller, peanut cooker and oil expeller, through this product line, the oil materials will be softened, activate the oil fat molecules, squeezing stability, and press well for once, yield efficiency is greatly increased. If you need you can equip vacuum fine filtration oil seed press with the peanut oil production unit, automatic refining filter, convenient and practical, separate out the microbe in the general, make the oil pure and clear.

At the beginning of squeezing, oil cylinder piston rising velocity should be appropriate, which means should add pressure easily and evenly in order to prevent the slanting heaps and slag flow out too much. In addition, must add pressure continuously but not discontinuously, until all the bread start to oil. Then, the operation should be based on standard "press lightly and continuously", adhere to the commercial constantly, until the end of squeeze.

During the operation, should also pay attention to the higher level of oil cylinder piston, in order to avoid the piston to get off the cylinder and cause accidents, do not exceed the specified position, namely oil cylinder piston stroke cannot be over the maximum. All the press operation process should be done under review tour. If the pressure gauge does not work or is destroyed, repair or exchanges should be timely; If encounter with serious slanting heaps phenomenon, should promptly adjust the whole heaps; if you encounter with a failure of safety valve, find out the reasons and eliminate as soon as possible.

Of easier operation, installation and commissioning, it investment small, only need less land space, but complete function of production, the small peanut oil production unit is useful. Less than a single press of the labor force is enough for small peanut oil production units, and our mechanical considerable design, it only need only 2 ~ 3 people running the entire line, also can avoid semi-continuous instability of material feeding manual. Lower investment, but with higher yields, in the present situation of the higher labor cost, the semi-continuous make the worker safety higher temperatures.

Pretrat Oilseeds

Our life is strongly connected with the oil in every aspect, the most basically, our three meals a day needs the edible oil. The edible oil sends our food into more delicious, particularly some vegetables cannot display its nutrition role until being cooked through the edible oil.

Meaing animal or vegetable oil which is used in food cooking process, the edible oil is also called "cooking oil". Under the normal temperature edible oil is the liquid state, but massive nutrients is included in this liquid, in the cottonseed oil includes the massive essential fatty acids, the linoleic acid content is the highest, may reach 44.0-55.0%, the linoleic acid can suppress cholesterol in the blood of human body, is advantageous in protecting human body health. In addition, in the cottonseed oil also includes 21.6%-24.8% palmitic acid, 1.9-2.4% stearic acids, 18%-30.7% oleic acids and a spot of arachic acids, digestion absorption rate of the human body to the cotton oil is 98%. The massive linoleic acid included soybean oil has an important physiological function. If baby lacks the linoleic acid, the skin becomes dry, the squama crumb accumulates, the growth will slow down; if senior citizen lacks the linoleic acid, will cause cataract and cardiovascular and cerebrovascular diseases.

Ordinarily the edible oil we see is shines limpidly, but before the oil becomes edible it must go through several working procedure, even if must pass through the multi-channel working procedure before the processing. Pretreatment for Oil Processing is consisted of oilseed cleaning and selecting, oilseed dehulling, oilseed softening, oilseed flaking, oilseed filtering and oil extruding.

The oilseed cleaning and selecting machinery must be earnest in the preparation of dangerous it will face during the oil process. Perhaps the impurity in oilseed will damage the oil mill equipment in cleaning and selecting process, maybe the impurity in seed will stop up the equipment. Prevent chaff from absorbing oil as well as being expelled from the oilseed cleaning equipment. Stone in oilseed possibly damages the screw in the oilseed cleaning and selecting oil extraction equipment and the sand in oilseed can fray the machine.

After cleaning, the oilseed for example peanut needs to transmit to separate the kernel in the oilseed dehulling equipment. Peanut which is still unhulled will be recycled within the equipment until properly dehulled. The efficiency of the dehuller is about 95 to 98 percent, with the rate of broken kernels at 2 to 5 percent. Before sent to the oilseed conditioner for further processing, oilseed will go through the machinery to increase the moisture and temperature to soften them. Those oilseeds with more rigid structures and lower moisture content are then processed into powder by the oilseed flaking mill. Then oilseed will be conveyed to oilseed flaking machine to burst its cell tissue, increases its surface area to enhance oil extraction rate. After extracted from the oilseed, the oil will be conveyed to oil filtering machine.
