Hydraulic Oil Presses VS Screw Oil Presses

When choosing an oil press, Ipeople don't know whether to choose a screw oil press or a hydraulic oil press. Oil press,screw good or hydraulic good? In fact, both have their own advantages and disadvantages. The hydraulic oil press is suitable for cocoa beans, olives, sesame walnuts and other bulk oil with a special flavor, and the screw press is suitable for larger amounts of soybean, peanut and canola oil.

Screw oil press

QIFENG 6YL-170 Avocado Oil Press is composed of vacuum filtration system, automatic heating device and control system. The product is reasonably designed with advanced performance and is suitable for pressing various oil seeds. It can be pressed directly, saving time and effort, processing large quantity and high oil yield. The oil quality is clear and pure, without foam and impurities. The avocado oil press can be fully automated with the automatic feeding machine produced by our company.

Advantages

As the screw press goes through three to four times of extrusion, the oil yield is higher than that of the single extrusion hydraulic oil press. And because of the simple mechanical structure of the left and right screw presses, it is not easy to break down; the equipment investment is small and the processing capacity is high. A device can process rapeseed, soybean, peanut, cottonseed, tea seeds and other granular oil, so also known as multi-functional oil press: screw press is made of high quality mold steel CR12 processed by quenching and fine grinding to ensure that at least 400,000 kg of oil, tough and durable.

Disadvantages

It is a dynamic pressure friction oil. The oil has a black appearance and high phospholipid content, and the oil has a bad appearance. Need to cooperate with centrifugal oil filter for fine filtration.

Hydraulic oil press

Qi-Feng YZYJ-360(25KG) automatic hydraulic oil press machine, easy operation, low cost, widely used in family and small oil factory.
This hydraulic oil press machine is suitable for cold pressing or hot pressing many oil seeds and oil plant, Especially for pressing sesame, pine nut, Especially for pressing sesame, pine nut, walnut, and so on valuable oil seeds.
Full automatic hydraulic oil press is a small oil press which is most convenient in operation, highest yield efficiency, as well as least replacement spare parts.

Advantages

Traditional oil extraction principle combined with modern technology. Compared with ordinary oil presses, it has high efficiency, environmental protection and energy saving, high added value of products, no loss, no noise, physical pressing without heating, no addition of any chemical raw materials, no oil washing, easy operation, no wearing parts, and long service life. One of the major advantages of the hydraulic oil press is that the pressure of the equipment is hydrostatic, the mechanical friction of the oil is very small, the oil is very clear and can be consumed directly without any treatment, convenient and safe.

Disadvantages

Unlike the hydraulic oil press, hydraulic oil press is a closed hydraulic system, only part of the leakage of oil will make the whole machine useless. Oil yield is relatively low, a single function less, oil in the pre-pressing process workload, the need to crush, steam, fry, large investment in equipment, small output.
