Abstract: Rapeseed processing technologies of dehulling, cold pressing and expansion were assembled to develop a new process of dehulling-cold pressing-expansion for double-low rapeseed, then pilot test was conducted. The optimization technical parameters of the process were confirmed: adjusting water content to 8%, dehulling machine rotating at 1500 r/min, cold pressing at room temperature, expansion inlet temperature 95℃, water content 9%, feeding motor rotating speed 900 r/min, extraction time 100 min, material height in cases of rotating extractor 1.2～1.3 m, quantity of pouring solvent 1.5 m³/h. Cold pressing oil approaches the Standard of National Ⅲ Rapeseed pressing Oil. Rapeseed Meal with a protein content more than 46% meets the Standard of National Ⅰ Low-glucosinolate Rapeseed Meal for Fodder. The processing cost is 142.85Yuan/t, which is less than that of pre-pressing extraction process by 20%. The new process increases producing capacity by 60% than that of pre-pressing extraction. The new process can improve quality of oil and meal obviously, reduce production cost, increase producing capacity. The industrialization and application of the new process are promising.
