Groundnut Oil Processing Methods

The ancient method of squeezing groundnut oil is very strict on raw materials. Raw material is the basis of groundnut oil. In the ancient method, groundnut is pressed with fresh peanuts, crushed, steamed, Fried, pressed and cold stored. Every process is strictly checked to ensure every detail, but the oil yield is relatively low. Because the utilization rate of raw materials is relatively low, the ancient method of squeezing has gradually put forward the stage of history, modern groundnut oil extraction machine emerged at the historic moment, the groundnut oil extractor provided by ABC Machinery combines the ancient method of pressing technology and modern technology, conforms to the needs of the times, the production of edible oil quality is high, healthy, suitable for people’s living needs.

To make groundnut oil, it is necessary to clean, peel, separate, dry, crush and peel peanut kernels, roll embryos, steam fry, press and filter peanuts. The main process of groundnut oil processing plant is as follows:

• Cleaning: the impurity rate shall not be more than 0.1%.
• Shell stripping and separation: the kernel content of the shell is not more than 0.5%, and the kernel content of the shell is not more than 1%.
• Drying: temperature: 95-100, time: 60-90 min, moisture: 4-5%.
• Crushing: 6-8 petals.
• Peeling: the peeling rate is 90%.
• Billet rolling: the thickness is less than 0.5mm.
• Steam and fry: 5-7% water, 110-115 temperature.
• Pressing: the primary crushing rate is 76-78%, and the secondary crushing rate is 12-14%.

Large scale oil press machines are found in milling plants that produce large amounts of oil from a variety of seeds. These are also available in a variety of models, sizes and power that it is able to generate while pressing seeds. The automatic integrated oil press machine is also another popular one because of its ability to work with minor supervision.  Oil milling plant owners can be able to use this oil press machine to produce quality oil for a long time.

Since oil press machines are varied in their overall output it is important for a buyer to purchase a machine that meets their needs and will be profitable in the long run. These machines can be purchased online or at the manufacturing plant where they are built so that they are used in the production of oil.

Oil Pressing
KMEC’s oil mill machinery also includes oil pressing and on the company’s website you will find oil pressing tips. They mentioned that in order to effectively press the oil, the temperature must be between 60 and 70 degrees so the proteins will not break down in the oil and to ensure that the cold pressing is done right. In hot pressing of the oil, the temperature needs to be above 111 degrees.

Benefits of Oil Mill Machinery
One benefit of the oil mill machinery is that there will be less residual oil after you process or refine the oil. There is also a reduced chance of dangerous accidents while working with the oil and you will be able to process several tons of oil per day, which ensures a quicker delivery for the client.

Oil Refining Plant
Another aspect of KMEC’s oil mill machinery is the oil refining plant. KMEC gives you the option of two types of refining plants. The batch oil plant is designed for low levels of oil extraction and production while the continuous refining plant is for larger batches of oil. In conclusion, KMEC oil mill machinery offers an excellent way of producing and extracting oils.

First, take off the hulls or seed coats from the seed. The hulls should not be thrown away because the hull of some seeds could be very useful. Take for instance the hulls for sunflower and soy are used as an additive to animal feed. Secondly, separate the seeds from chaff. Several methods are used for this process. The two steps can be carried out using some devices and there is a wide range of technologies for the above.

Seeds to be used in seed oil press process need to meet certain conditions. The most important thing that is compulsory is for the seeds to be thoroughly clean. This is because the process of getting oil from the seeds uses machines, which are prone to damage in case they come into contact with dirt. Some people think that it is only stones and large particles of dirt that can damage the machines but any type of dirt or sediment can cause damage to.

Besides, the seeds should be separated from chaff totally, so that the process of oil absorption goes on smoothly. The seeds to be used must be dry to prevent the machinery from clogging. Besides, use of moist seeds will lead to decrease in yields of oil. The seeds used have to be warm if you want to get the right amount of oil from them. The actual temperatures required should be between 100 and 160 degrees Fahrenheit.

It is possible to achieve this temperature using various means. You can use an oven, double boiler, or solar collector to warm small amount of seeds. On the other hand, for large amounts of seeds, use a heated hopper. It is important to note that all of the above conditions must be met in order for you to get the right yield of oil for a given amount of seeds.
