Abstract: Rapeseed dehuller, twin-screw press and expander were assembled to a new process for double-low rapeseed. The
technical and economic feasibility of the new process were analyzed. It can reduce conversion cost, improve quality of oil and meal
and increase economic benefit. The conversion cost of new process is Yuan·t-1, which is less than pre-pressing extraction
process by 20%. Cold pressing oil meets the standard of the second grade rapeseed oil of GB 1536-1986. Rapeseed meal meets the
standard of the first grade low-glucosinolate rapeseed meal for fodder of NY 417-2000, which protein content is more than 46%. The
