YSZ286
Scope of application
The YSZ286 7D Double-Screw Oil Press is a large-scale pressing machine designed to help large-capacity vegetable oil plants reduce equipment investment, minimize factory space requirements, and cut down on energy, water, and steam consumption.
After being crushed and conditioned, the oil-bearing material is fed into the pressing chamber via a variable-frequency, quantitative feeding screw conveyor. Inside the pressing chamber, two spiral press shafts are arranged, and under the combined squeezing and shearing action of these shafts, the oil-bearing material achieves optimal oil extraction.
This machine is suitable for various oil-extraction processes, including high-temperature, moderate-temperature, and low-temperature methods. It can be widely used to press and produce oils from a diverse range of vegetable materials such as soybeans, rapeseed, sunflower seeds, cottonseed, peanut kernels, corn germ, flaxseeds, and dried coconut—making it the ideal oil-extraction equipment for large-scale vegetable oil plants.
Performance Features
The YSZ286 7D double-screw oil press, after standard pretreatment of the oil-bearing material, boasts the following key performance features:
● Seven Low Innovations:
① Low temperature: Room temperature to 60°C;
② Low crumb: 6%–7%;
③ Low energy consumption: Save 60 yuan per ton of material;
④ Lower consumption: Reduced by 1%;
⑤Low emissions: 50% carbon reduction;
⑥ Low-scorch residue: Reduced by 60%;
⑦ Low Failure Rate: 3-Year Warranty.
● Low equipment investment: The rolling and steaming/frying process sections, including their respective machinery, can be eliminated.
● More durable: The double helix design offers a unique structural advantage, significantly reducing inefficient wear on vulnerable components caused by the oilseed material inside the press chamber—allowing these critical parts to last over 180 days.
● Smooth operation: The strength design features a safety factor exceeding 3 times, with a box-frame structure that ensures no deformation over 20 years.
● High quality: The oil extracted is light in color, and refining improves the yield.
● High productivity: Each unit delivers high output, requiring minimal workshop space while maintaining a sleek and elegant design.
● Nine-stage pressing: Feed in, oil out—simply form the cake, reducing mill time and minimizing mill feed volume.
● Easy maintenance: The juicing cage features a hinged ear plate design that ensures operator safety while also reducing labor intensity.
● The screw end face features a labyrinth seal, effectively addressing the issue of residue leakage and making disassembly easier at the screw joint surface.
