Comparison of screw oil press machine and hydraulic oil press machine

Which one is better of screw oil press machine and hydraulic oil press machine. This two types oil press machine have many advantages and disadvantages. The hydraulic oil press machine is suitable for specially flavored and nutrient-flavored oils such as cocoa beans, olive oil and sesame seeds and walnuts. the screw oil press machine is suitable for oils material with large amounts, such as soybeans, peanuts and rapeseed.


The advantages of the screw oil press machine: The oil output rate of the crew oil press machine is higher than one pressing hydraulic oil press machine due to the snail passes through the three to four stages of pressing. And screw oil press machine are not easy to malfunction because of the simple mechanical structure; the equipment investment is small, the processing capacity is high, one set oil press machine can process granular oil such as rapeseed, soybean, peanut, cottonseed and tea seed, so it is also called multi-functional oil press machine. It is made of high-quality steel CR12 after quenching and grinding, at least to ensure that can press oil is more than 200,000 kg, which is tough and durable.

The disadvantages of crew oil press machine: It belongs to dynamic pressure friction oil production. The apparent of oil is black, contains high phospholipids, and the oil is not have a good apparent. It needs to be combined with centrifugal oil filter to be finely filtered.

The advantage of hydraulic oil press machine: It also called hydraulic scent machine, It combined the traditional pressing principle with modern technology, It has high efficiency, environmental protection and energy saving, high added value of products, no loss, no noise, no need for heating in physical pressing, no addition raw materials, no need to clean oil, easy to operate, no wearing parts and very durable compared with ordinary oil press machine. The biggest advantage of the hydraulic oil press machine is that the pressure of the equipment is static pressure, the mechanical friction of the oil is very small, the pressed grease is very clear, and it can be used directly without any treatment, which is convenient and safe.

The disadvantages of hydraulic oil press machine: The hydraulic oil press is a hermetic hydraulic system. If only one part of the oil leaks, it will make the whole machine useless. The oil rate is relatively low, the single machine can be small, and the oil material has a lot of work in the pre-pressing process. It needs to be crushed, steamed and fried, and the cake is invested, and the equipment investment is small, and the output is small.
