The screw press is a device that uses physical extrusion to dewater the device. The device includes driven System, feed box, spiral auger, screen, pneumatic material blocking device, sump, rack, etc.
the material enters into the equipment from the feeding box and is subjected to progressive pressure extrusion under the conveying of the spiral auger.
Excess water is discharged from the liquid outlet through the screen, and the moisture-removing material is continuously transported by the spiral auger.
The top opening and blocking device is discharged from the discharge port by the discharge port.
It is truly low energy consumption, high output, low moisture, and secondary circulation for material to save a lot of processing costs.
II. Working principle
The dewatering process of the screw press dewatering machine is divided into two stages. The first stage uses the screw auger to dehydrate. The spiral auger has three sections: the transmission section, the compression section and the discharge section, and the transmission space become smaller gradually to press the materials stronger and make the material extruded water.
The second stage uses a material-blocking device to dewater. When the material enters into the discharge section of spiral auger, the spiral auger applies axial thrust to the material to push it out of the discharge port, while the pressure device is pressurized by the pneumatic device which applies a reverse force to the material to be pushed out, thereby forming a pressing force to the material to realize the dehydration.
III. Main Advantage
1. Aiming at the complex material of biogas residue, it is not afraid of wear and tear, the effluent is smooth, and the purpose of press separation is realized by the effective cooperation of screw and screen mesh.
2. The extruding separator has successfully solved the problem of screen mesh clogging. The core technology is the cooperation of spiral and screen mesh to realize the self-cleaning function of screen net, that is, the special device and screw can interact to agitate the material. One is to avoid holding the shaft of the material, the other is to realize the material particles rubbing off the clogging material of the screen in the process of spiraling forward.
3. The control of tail cone is different from that of spring, hydraulic pressure, handwheel and so on, but the pneumatic device with very low maintenance cost can effectively realize the "back pressure" control of material press by special design. That is to say, after a certain press pressure is set, the device will automatically realize the control of the press force of the material, and avoid the slag from suddenly drying and humidifying. At the same time, the extruding separator is especially suitable for assembly line operation because of adopting the principle of superposition compression. It avoids the malpractice that the ordinary press needs to be centralized.
4. The special angle design of the feed box can effectively prevent the "bridge building" phenomenon of some sticky materials. Although it is a small detail, once the "scaffolding" is produced at the production site, it will cause the material to stop without feeding and have to stop, which is very troublesome. So the details decide the success or failure;
5. the press sieve screen all two half screen, for food processing and fruit and vegetable processing industry, can be easily opened and thoroughly cleaned;
6. sandblasting treatment, beautiful shape, simple structure, low speed transmission, high torque output, low noise, no vibration, at the same time drive less parts, need to be replaced less easily damaged parts, low maintenance cost. It’s your solid-liquid separation and processing of fruits and vegetables choice.
IV. Application range

Integrated Screw Oil Press Instruction
Integrated screw oil press is a compound machine which can squeeze and filter oil and at the same time, squeeze many oil crops including peanuts, soybeans, tea seeds, and cottonseeds etc.
Integrated Screw Oil Press Application
The automatically integrated screw oil press adopts the newest technology and qualified stainless steel, with high oil yield and vacuum filtering. It is ideal for hot pressing of sesame, soybeans, rapeseeds, cotton seeds, tea seeds, sunflower seeds, castor seeds, and almonds etc. Also, it can be used for cold pressing of other oil materials. The integrated screw oil presses are widely used in small-sized and medium-sized oil plants.
Integrated Screw Oil Press Features and Benefits
★Advanced Technology: reliable performance, easy operation, and convenient maintenance.
★High oil yield: compared with the old-style equipment, the oil yield can increase 2%-3%.
★Lower Power Consumption: integrated screw oil press can decrease 40% power with the same output.
★Wide usage: the automatic screw oil press can press multiple oil crops, such as peanuts, sesame, sunflower seeds, and soybeans etc.
★Pure oil: vacuum filtering device of the automatic screw oil press can ensure the pure oil conforming to the health and quarantine standard.
★Automatic control: this oil press can control the squeezing temperature automatically; built-in vacuum shunt can make the efficient separation of oil and residue.
★Covering small floor space: only 10-20 square meters can satisfy the oil processing machine.
Integrated Oil Press Working Principle
When the oil press runs, the processed oil materials enter into the squeezing chamber through the hopper. The screw rotor propels the oil materials inward and squeezes them. The oil materials in the squeezing chamber are motorial. In the high-pressure chamber, there is great friction resistance between oil materials and squeezing spiral or squeezing chamber, thus the micro materials can create friction. On the other hand, the squeezing screw diameter is gradually thickening and the screw pitch is gradually decreasing, so when the squeezing screw rotates, the screw threads can propel the oil materials forward or outward. The heat generated by friction can improve the yield of the oil press, and let the oil flows from the gaps. When the overflowing oil flows onto the oil filtering barrel through the oil tray, the vacuum pump pumps the air in the barrel, and then negative pressure forms in the barrel. The oil is pumped into the barrel through the filtering cloth and the oil residues are left on the filtering cloth.
Difference Between Cold Pressing and Hot Pressing
1. The cold pressing of oily seeds does not require any preconditioning of the input material. The only requirement is that the input seed is 98% clean and free of metal and stone particles. The hot pressing of oily seeds should be roasted in advance.
2. The cold pressed oil has better color and luster than hot pressed oil; however, the hot pressed oil smells better than cold pressed oil.
3. The cold pressed oil has lower oil yield than hot pressed oil.
4. When choosing between cold and hot pressing technologies, one must always consider the intended use of the produced vegetable oil, as well as other factors influencing return.
