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.
