How to improve the oil output rate of oil press?
Oil press machines are widely used in the oil industry for extracting oil from various oil corps. The selection of an oil press machine depends on several factors, but the most important factor is the oil output rate. The higher the oil output rate, the more efficient the machine is. However, several factors affect the oil output rate, including moisture content, temperature, and operation experience.
Factors Affecting Oil Output of Oil Press
Moisture Content
The moisture content of the oil corps is a crucial factor that affects the oil output rate. If the moisture content is too high, it can affect the quality of the oil and reduce the oil output rate. Therefore, it is essential to ensure that the moisture content of the oil corps is within the recommended range before feeding it into the oil press machine.
Temperature
The temperature is another crucial factor that affects the oil output rate. The temperature should be within the recommended range to ensure optimum oil output. If the temperature is too high or too low, it can affect the quality of the oil and reduce the oil output rate.
Operation Experience
The operation experience of the user is also a crucial factor that affects the oil output rate. If the user is not experienced in operating the machine, it can affect the quality of the oil and reduce the oil output rate. Therefore, it is essential to ensure that the user has adequate knowledge and experience in operating the machine.
Techniques for Improving the Oil Output of an Oil Press
Cleanliness of Raw Materials
Inadequate cleanliness of raw materials can affect the oil output rate. Sand or impurities can enter into the press chamber and reduce the oil output rate. Therefore, it is essential to ensure that the raw materials are clean and free from impurities before feeding them into the machine.
Rough Surface of Screw Shaft or Mouth of Exit
The rough surface of the screw shaft or the mouth of the exit can affect the feeding and discharging of the material, which can reduce the oil output rate. Therefore, it is essential to polish the rough part with an emery cutter or mix the material with husk, which has a big friction force with the cake. Adding a little water into them and starting the machine can polish the mouth of the discharging cake.
Rotating Speed of Screw Shaft
The rotating speed of the screw shaft is also a crucial factor that affects the oil output rate. If the speed is too high or too low, it can affect the quality of the oil and reduce the oil output rate. Therefore, it is essential to adjust the speed until it meets the standard.
Grinding of Screw Shaft
If the screw shaft is worn out, it can affect the oil output rate. Therefore, it is essential to grind the screw shaft and replace the spare parts if necessary.
Preheating and Steaming of Materials
Before using the oil press machine, it is essential to check the whole machine and lubricate each part that needs lubrication. This can improve work efficiency and oil output rate while decreasing the friction force of spare parts. Additionally, steaming and roasting materials like sesame, peanut, sunflower seeds, and other oily plants before feeding them into the machine can improve the oil output rate. For soybean, which has low oil content in China, users usually press them in a cold pressing pattern.
Resting of Machine
If the oil press machine passes through continuous pressing equipment, the temperature will gradually increase. When it runs for too long, it is essential to rest for a while to prevent the machine from overheating. Additionally, preheating the machine before starting it and pressing previous oil cake or a small amount of oil repeatedly when the temperature of the oil press equipment reaches about 60°C can improve the oil output rate.
By following these tips and techniques, users can improve the oil output rate of their oil press machines and enhance their efficiency in the oil industry.
