银杏脱壳技术与设备研究

Study on a key technology and equipment of ginkgo exuviating

研究了银杏的脱壳方法,并以脱壳率(出现脱壳银杏所占的比率)、整仁率(完整果仁所占的比率)和碎仁率(碎果仁所占的比率)为观测指标,进行了银杏挤压脱壳试验,结果表明,采用碾搓法脱壳,可使银杏一次脱壳率(P1)不低于65%、碎仁率(P3)不高于10%.在此基础上研制了银杏脱壳设备.

Gingko extrusion - grind exuviating tests had been studied with un - cracked rate （i.e. P1 - Un - cracked gingko quantity in per kilogram tested material）, integrated kernel rate, （i. e. P2- Rounded kernel of shelled gingko quantity in per kilogram tested material）, and smashed nut rate （i.e. P3 - Smashed gingko quantity in per kilogram tested material） as analysis indexes. The experiments of Gingko exuviating showed, that with once extrusion - grind exuviating method, P1 is not less than 65%, while P3 is not more than 10%. A prototype instrument of gingko exuviating had been implemented based on this hulling theory.
