Palm Kernel Oil Expeller Machine Introduction

Automatic double-shaft palm kernel oil expeller can squeeze out most of the oil from fresh palm kernels by the high mechanical pressure. Palm kernel oil extraction machine has a large processing capacity and high oil yield which is special for crushing palm kernels, and its service life is three times higher than other ordinary oil press equipment. The oil press uses multistage pressurized propulsion and vacuum filtration system to improve the oil extraction efficiency and oil quality. The palm kernel oil expeller machine is also added with the seed frying and automatic heating function which changes the traditional heating method of cake grinding press, so as to shorten the preparatory work time, reduce the energy consumption & the abrasion of the machine and prolong the service time of expeller. If intermittent production, its pressing chamber can preserve heat automatically.

Palm kernel oil expeller can be used alone, and also can be worked together with other palm kernel oil processing equipment: palm kernel crushing machine and separation machine, palm kernel cleaning equipment, palm kernel steaming equipment, palm kernel oil filtration equipment and palm kernel oil refining device in the palm kernel oil production line. The specific palm kernel oil production solution is provided according to customer requirement.

Palm Kernel Oil Expeller Working Principle

plam kernel oil expeller working principle
The working principle of double shaft screw press is through the impelling action which is generated by two intermeshing screws rotating in opposite direction in the chamber, palm kernel is pushed forward. Meanwhile, as the shortening of the helical pitch, the volume of the pressing chamber is shrinking and pressure is generating, and the kernel is compressed that the oil in it is squeezed out. Then, the expressed oil flows out of the gap in the squeezed cage. At the same time, the residue would be pressed into cakes, and constantly discharged from the end of the squeeze shaft.

Main Features of Double Shaft Screw Oil Press

♣ Specially designed double shaft structure

  1. Double shaft cold pressing technology does not need some oilseeds pretreatment sections which are necessary for hot press technology, such as crushing, softening and steaming section, so fewer machines used in palm kernel oil extraction. No environmental pollution, low power consumption, and low production costs.
  2. Sufficient promoting.
  3. One-time squeeze.
  4. The oil yield can be up to 93%, and the residual oil content is low.
  5. The reasonably designed double helical shaft has a large theoretical compression ratio, the oil in the chamber can be compressed and expanded up to 5 times, which can achieve the combining press of thick material cake and thin material cake.

♣ Strictly heat-treated steel fittings

  1. The machine has a compact structure, which is durable and sanitary.
  2. Machine parts are made of carburized steel, which has high strength, toughness and low-temperature impact toughness.
  3. Through wear treatment, long service life.

♣ Vertical squeezing cage, and hinge support at both ends

  1. No accumulation of slag in squeezing cage.
  2. Smooth discharge of oil
  3. Easy to maintain and repair after putting into production.

♣ Unique material cake discharge device: the sizes could be stepless adjusted.

  1. When processing, palm kernel oil production equipment could be adjusted timely according to the thickness of the cake.

♣ Cold pressed oil can keep the original natural ingredients

  1. Such as unsaturated fatty acids, vitamins, protease, lecithin, and trace elements.
  2. Maintain the palm kernel oil’s original color, scent, and taste.

♣ Cold pressed palm kernel meal

  1. It can be used for high-value food.
  2. It is suitable for making animal feed, fertilizer, fuel or protein extract.

Palm Kernel Oil Press Machine Applications

  • Our palm kernel oil press is suitable for pressing high-oil-content oilseeds such as shelled peanuts, tea seed kernels, sunflower kernels, cottonseed kernels, rapeseed kernels, walnuts, rubber seeds and peeled soybeans at room temperature or at low temperature.
  • Suitable for traditional hot pressing of vegetable oil.
  • Suitable for hot pressing special oilseeds, like flax seeds, safflower seeds, almond kernels, rose seeds or low-temperature pressing of them after they are shelled or peeled.

What is Palm Kernel Oil?

Palm kernel oil is a type of vegetable oil which is high in saturated fat and Omega 6, presenting serious health concerns. It is derived from the palm kernel, grown on the African oil palm tree. Oil palms originated in West Africa. Palm kernel oil is an important part of the oil market in the world, at present, it is more than 30% in the oil production. Oil palm is a kind of agricultural crop of having blossom and fruit in four seasons as well as having harvest all the year round. It will continue to be commercial productive for 25 years.

Nutrient Content of Palm Kernel Oil

Palm kernel oil is also called saturated oil because it contains 50% saturated fat. Fat is consisting of saturated fat, monounsaturated fat, and polyunsaturated fats. The human body consumption of palm kernel oil up to 97%, as the same as all other vegetable oil, palm kernel oil not contains cholesterol.
As higher saturation oil, palm kernel oil was supposed to maybe increase cholesterol in human body serum. But later study of many specialists shows that edible palm kernel oil does not increase cholesterol in serum, on the contrary, have the trend of reducing cholesterol in serum. Because a host of research data shows that different saturated fatty acid has a different influence on blood fat. Palm kernel oil contains rich neutral fatty acid but contains little substance (1%) which promotes cholesterol. Palm kernel oil contains natural vitamin E, tocotrienols(600-1000mg/kg), carotenoid(500-700mg/kg), and linoleic acid(10%),all them are very benefits to the health of human body. Some researchers according to different race (European, American, and Asian) to study. The result shows that palm kernel oil is a kind of healthy edible vegetable oil which completely meets the requirement of human body needs.
