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 142.85 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 new process come up to high profit .Its industrialization and application are promising.

Key words: Rape (Brassica napus), Double-low rapeseed, Dehulling, Cold pressing, Expansion, Process
