The dewatering screw press machine is a new type of press and dewatering equipment which can be moved by wheels, it has double screw structure or single screw structure. It can make continuous and slow dewatering.

The dewatering screw press has the characteristics of low speed and high pressure. The speed is 12RPM after double deceleration of reducer and gearbox. The material contact parts are made of high quality acid and alkali resistant stainless steel. The double dewatering screw press includes the front and rear sections of the screw are extruded in the positive and negative directions to form a “twisted towel” work effect. Through the large area contact between the screen and raw material and the cone at the tail end, the pressure is increased to achieve the solid-liquid separation effect. The humidity of residue discharge can be controlled and adjusted according to the requirements.
Besides, the single dewatering screw press includes only one piece screw inside, the longer screw will form big pressure between the end of screw and residue outlet port.

From peanut butter and coconut oil to CBD products and fragrant soaps, oil extraction is the process behind many valuable items derived from agricultural products. Creating those products calls for an oil extraction machine. Oil extraction machines are a versatile type of machinery, helping agricultural businesses do more with their yields. These expeller pressers are typically based on a screw system, putting heat, friction and pressure to work as they squeeze oils out of different materials.
Let's take a closer look at how oil extraction machines work, how they're used and what they're made of.

An oil extraction machine, also called an oil press or expeller, uses high pressure and heat to “squeeze” the oils out of a plant product. Those products — including seeds, nuts, vegetables, fruits and leafy plants — release their oils through this mechanical process, which is often done without adding any chemicals.
Oil extraction machines typically use a screw press. Some products, like groundnuts, need to be shelled or peeled before moving through the screw press. The peeling process might use powerful centrifugal forces or airflow from a fan to separate lightweight shells from the heavier nut.
After peeling, the product is fed into the screw system, which comprises a screw inside a high-pressure cylindrical chamber. The material moves through the screw, generating friction and heat. While the high pressure squeezes out much of the oil, the heat contributes, too. It can denature some of the proteins in the product and increase the viscosity of the oil for easier movement.
As the oil is pressed out, it seeps through a screen or filter to ensure that no solids or fibers move with it. This creates a clean, smooth product. The leftover pressed seeds form a hard cake that is removed from the machine, and the oil flows out into a separate container.

The heat generated in this process can affect some materials in undesirable ways, and harder products like nuts generate more heat than softer products like fruits. To combat the extra heat, some users choose to cold-press certain materials by controlling the temperature in some way. They might use some additional chemicals or a centrifugal system to help draw the oils out without adding more pressure.
Oil extraction machines are very versatile. You can find different styles to accommodate various agricultural products, and the oils can be made into numerous items, like cooking oils, fragrances, cosmetics, soaps, pet food, biofuel, wood treatments and paint.
Some of the plant sources that work with oil extraction machines include:
The amount of oil you get from each product can vary. Peanuts, for instance, have a high oil content of 45-52%, while hemp seeds contain about 25-30% oil. In some cases, the leftover materials generated from the extraction process are valuable, too. Canola meal is the material left after the oil is extracted from the seeds, and it is 38-42% protein. It also contains a good balance of amino acids, making it a popular additive for livestock feed. Oil extraction machines can help expand one product in many different avenues.
The price of oil products makes them a great way to potentially get more value out of crops. Many types of oils, especially those that are used in biofuels, have seen significant price increases. If you're looking for something else to do with a crop, such as new revenue channels or using up extra inventory, oil extraction could be a good option.
Oil extraction machines can come in several configurations, but here are some of the main components you'll typically find:
You'll find various other parts in an oil extraction machine like lock nuts, rings, seals and gaskets that make up these larger components and link them together. These parts might be made of metals and elastomeric materials, both of which offer long-lasting durability in the tough, messy conditions of oil pressing.
Global Elastomeric Products creates a wide range of elastomeric products to support your oil-pressing operation. We produce a variety of tools, including custom rubber molding for the agricultural industry, and we can help you keep your equipment running smoothly or bring new machinery to life with custom rubber molding.
