Hydraulic and screw oil pressers are the main types of oil pressers used in edible oil processing industry, and they have their own advantages and disadvantages. If you don't know how to choose them, Henan Glory Company will introduce you the the advantages and disadvantages of hydraulic and screw oil pressers, and you can choose suitable oil presser to buy based on your requirement.

1. The the advantages of hydraulic and screw oil pressers

Advantages of hydraulic oil presser:

Hydraulic oil pressers

1) High oil quality: Hydraulic oil presser uses physical way to extract oil, and no heating, and the pressure of the equipment is hydrostatic, and the mechanical friction of the oil is very small, so the oil is very clean and can be consumed directly without any treatment.

2) Suitable for cold pressing: Especially for sesame, peanut, walnut and so on.

3) Environmental protection and energy saving: There is less noise during operating. It is physical pressing without heating, no addition of any chemical substances.

4) Easy to operate and cost less: Suitable for small investors, family use or small scale edible oil extraction production line.

Advantages of screw oil presser:

Screw oil pressers

1) High oil yield rate: The screw oil presser presses the oil by continuously pushing the screw shaft forward and squeezing the material. As the screw oil presser goes through 3-4 times of squeezing, the oil yield is higher than that of a hydraulic oil presser with a single squeeze.

2) Three types and many models can be chosen: Henan Glory Company provide three types of screw oil presser: single screw oil presser, screw oil presser with automatic temperature control system and screw oil presser equipped with vacuum filtration system and automatic temperature control system. Specially, the last one is very popular among the small investors. The oil quality is clear and pure with less foam and impurities after pressing. And they also have different models for different processing capacity.

3) Durable and stable: Because of the simple mechanical structure of the left and right screw presses, it’s more durable and stable.

4) Suitable for pressing different oil seeds: Screw oil presser is reasonably designed with advanced performance and is suitable for various oil seeds pressing, such as soybean, peanut, cottonseed, sunflower seeds and so on.

5) High automation: It can be used singly, also can be used in full continuous edible oil processing line.

2. Disadvantages of hydraulic and screw oil pressers

Disadvantages of hydraulic oil presser:

A hydraulic oil presser

1) Low oil yield rate: Once pressing, the oil yield rate is high.

2) Low automation and small processing capacity: It can not process large scale capacity and must be operated by workers.

3) Difficult in fixing: Different from screw oil presser, the hydraulic oil presser is a closed hydraulic system, if only part of the leakage of oil will make the whole machine useless.

Disadvantages of screw oil presser:

Screw oil presser with filter

1) ‌More nutrient loss: The screw oil presser generates more heat during the pressing process, resulting in more nutrient loss of the oil, and is not suitable for pressing high-end oils such as walnuts and peony seeds.

2) ‌More impurities: The oil pressed by the screw oil presser has more impurities and must be finely filtered by a centrifugal oil filter before it can be used, which increases the cost and time of subsequent processing.

3) Complex operation: The operation of the screw oil presser is relatively complex, and it is difficult to learn by yourself. It requires certain technical training to master it.

The above is Henan Glory company's introduction of the advantages and disadvantages of hydraulic and screw oil pressers to make you more aware of their differences and make better choices.
