Palm spiral oil press is a mechanical device specifically designed for extracting palm oil from palm fruits or kernels. This oil press has been widely used in the palm oil production industry due to its high efficiency, durability, and ease of operation.
Palm spiral oil presses are mainly divided into two types: single spiral and double spiral. The double helix oil press is more suitable for large-scale production due to its stronger squeezing force and higher oil yield. Its structure mainly includes components such as frame, cross coupling, double axle box, hopper, squeezing cage, squeezing screw, and hydraulic control system. Among them, the design of the double helix structure can generate stronger squeezing force and is less prone to slipping, with strong self-cleaning ability, making palm fruit or kernels more thoroughly pressed.

working principle:
The working principle of the palm spiral oil press is mainly based on pressure and friction. In the fixed space of the squeezing cage, two opposing squeezing screws (spiral shafts) engage with each other in a special way, generating continuous squeezing force. Palm fruit or kernels are subjected to gradually increasing pressure and friction under the push of the snail, thereby squeezing the oil from the kernels. The pressed oil flows out from the gaps in the squeezing cage, while the fruit residue is pressed into flaky cakes and discharged from the end of the squeezing shaft.

The oil extraction process of a palm screw press can be divided into three stages:
1. Feeding (pre pressing) section: Palm fruits or kernels enter the squeezing chamber through the feeding hopper and begin to be subjected to initial compression.
2. Main oil extraction stage: Under the continuous rotation of the screw, the kernels are subjected to gradually increasing pressure and friction, and a large amount of oil is squeezed out.
3. Cake making (heavy pressure oil extraction) section: The fruit residue is further compressed into a cake shape, while the residual oil is also squeezed out to ensure maximum oil yield.

Advantages and characteristics:
Efficient oil extraction: The design of the double helix structure enables the oil press to generate stronger squeezing force, thereby improving the oil extraction rate.
Strong durability: Made of national standard grade steel and spare parts, it has the characteristics of strong corrosion resistance, high acid resistance, and durability.
Easy to operate: The structural design is simple and compact, integrating mechanics and electronics, making the operation more convenient and efficient.
Low consumption and high output: It has the characteristics of low energy consumption and high output, which not only saves time, labor, and electricity, but also reduces investment costs.
Wide applicability: Different models and capacities of oil presses can be selected according to different production needs to meet the production needs of different scales.

Application areas:
Palm spiral oil press is widely used in the production and processing of palm oil. The palm oil extracted from it has important application value in various industries such as cooking, baking, and biodiesel. In addition, refined palm oil can be further converted into various derivatives such as puff pastry, frying oil, etc., which are widely used in industries such as pastry and fast food.
