Edible oil extraction machine is a device that uses mechanical pressing to extract oil from oilseeds. The basic principle is to use the screw in the edible oil extraction machine to fully squeeze the oil in the oilseed to obtain edible oil. However, sometimes we find that the oil yield of edible oil extraction machine is not good. In this article, we will start with factors such as oil seeds, oil press, operation, etc., and analyze the reasons and solutions for the low oil yield of edible oil extraction machine, help you understand why the oil yield of edible oil extraction machine is not good.

Oilseed issues

The quality and oil content of oilseeds are important factors that affect the oil yield and quality of edible oil extraction machine. Different oilseeds have different oil contents, and some oilseeds with low oil content may result in low oil yield of edible oil extraction machine. For example, peanuts and soybeans have high oil content, while rice bran and corn germ have low oil content. Therefore, when selecting oilseeds, high-quality oilseeds with high oil content should be chosen, and attention should be paid to the quality of the oilseeds.

The pretreatment of oilseeds

The pretreatment of oilseeds is an important factor affecting the oil yield of edible oil extraction machines. During the process of harvesting, transportation, and storage, oilseeds may be contaminated with impurities such as soil, stones, dust, or plant residues like branches, leaves, and petals. If oilseeds are not pretreated, these impurities will reduce the oil yield of edible oil extraction machines, and even some hard impurities like stones may damage the edible oil extraction machines. In addition, some oilseeds have hard shells, such as peanuts and sunflower seeds, which need to be crushed to release oil more effectively and improve the oil yield of edible oil extraction machines. Therefore, Henan Guorui Company provides various pretreatment equipment, such as shellers, vibrating screens, and magnetic separators. You can choose suitable equipment according to your needs and the amount of raw materials to be processed.

The pressing force and time of the edible oil extraction machine are important factors that affect the oil yield and quality. If the pressing force is insufficient, the oil in the oilseeds cannot be fully squeezed out, resulting in low oil yield of edible oil extraction machine. If the pressing time is not long enough, the oil in the oilseeds cannot be fully squeezed out, resulting in low oil yield of edible oil extraction machine. Therefore, when using the edible oil extraction machine, different pressing forces and times should be selected based on the characteristics of different oilseeds, such as their hardness and oil content, to ensure the optimal oil yield and quality of edible oil extraction machine to ensure the oil yield and quality.

Operation of edible oil extraction machine

The use of the edible oil extraction machine is also an important factor that affects the oil yield of edible oil extraction machine. If the edible oil extraction machine is not operated correctly or the parts of the edible oil extraction machine are damaged or aging, it will affect the oil yield of edible oil extraction machine. Therefore, when using the edible oil extraction machine, the operation should be carried out according to the instructions, and the parts of the edible oil extraction machine should be checked regularly to ensure that they are normal.

If the user does not operate the edible oil extraction machine according to the instructions, such as overloading or underloading it with oilseeds, or not cleaning it, it will affect the oil yield and quality. Therefore, when using the edible oil extraction machine, the instructions should be carefully read and the operation should be carried out correctly to avoid improper operation.

In addition, there are some operation skills that can help improve the oil yield and quality. For example, before pressing the oil, the oilseeds can be dried or sun-dried to increase the oil content in the oilseeds; during pressing, the oilseeds can be heated appropriately to make the oil in the oilseeds easier to squeeze out; after pressing, the pressed oil can be placed for a period of time to allow impurities in the oil to settle, and then filtered, which can improve the oil quality.

Maintenance of edible oil extraction machine

Maintenance of edible oil extraction machine is also a factor that affects the oil yield of edible oil extraction machine. If maintenance is not carried out for a long time, the parts of the edible oil extraction machine may be damaged or aged, resulting in low oil yield of edible oil extraction machine. Therefore, after using the edible oil extraction machine, it should be cleaned and maintained on time, and the parts should be replaced regularly.

First, the edible oil extraction machine should be cleaned regularly. Disassemble the edible oil extraction machine, clean it with clean water, and remove oil stains and impurities. Secondly, the parts of the edible oil extraction machine should be inspected regularly and replaced if they are worn or damaged, such as filter screens, belts, bearings, etc., to ensure the normal operation of the edible oil extraction machine. Finally, lubricating oil should be added regularly to ensure the lubrication effect of the edible oil extraction machine.

Environmental factors

Environmental factors also affect the oil yield of edible oil extraction machines. For example, low or high temperature, high humidity, etc. can affect the oil yield of edible oil extraction machine. Therefore, when using the edible oil extraction machine, an appropriate environment should be selected to ensure that the temperature, humidity, and other environmental factors meet the requirements.

Generally, the suitable temperature for the edible oil extraction machine is 20℃-30℃, and the suitable humidity is 50%-60%. If the temperature is too low or too high, it will affect the flowability of the oilseeds, resulting in low oil yield of edible oil extraction machine; if the humidity is too high, it will increase the risk of mold growth on the oilseeds, which can affect the oil yield and quality. Therefore, when using the edible oil extraction machine, an appropriate environment should be selected to ensure that the temperature, humidity, and other environmental factors meet the requirements.

In summary, the poor oil yield of edible oil extraction machines may be caused by multiple reasons. We need to carefully analyze the reasons and take corresponding measures to solve the problem.
