Pre-treatment of oil-bearing material means do material cleaning, husking, peeling, breaking, softening, flaking, puffing, heat-moisture treatment and drying before process oil pressing of the material, is on purpose of removing impurities of the material and make it of certain structural performance to accommodate different oil press technology. Base on different oil materials and oil extraction technology, the way of pre-treatment is different, either. The way of pressing is driven by mechanic force to press the oils. There are two types of extraction technology – pre-pressing and pressing, and pre-pressing is a traditional way of processing on oil material of high oil content.

Pre-pressing is a traditional way to process material of high oil content, the designed the pre-press technology from us has below features:
1. Applicable to rape seed, cotton seed, sunflower seed, safflower seed, etc.
2.Take use of puffed technology per clients’ request, is more energy saving and of high quality oil.
3.Take multi-grade filter for pre-pressed crude oil
4. The layout of workshop looks clean and tidy, production line looks simple and intuitive, the whole line can take completely automatic control.
