Abstract
rapid increasing in cultivation area due to favorable price temporarily and decreasing in consumer¡¯s demands caused by economic depressions recently, lead the price of Cynanchum wilfordii Hemsley to decline sharply. Thus, it may give rises to weakening of cultivation bases in Cynanchum wilfordii Hemsley. To investigate optimal mechanical peeling conditions of Cynanchum wilfordii Hemsley, protruded rubber, plastic pad, diamond shape¡¯s steel and palstic brush were introduced as blades and artificial stone, sand and small pebble were done as abrasives. The main results obtained were summarized as follows; 1. It took 2 minutes per 1kg in mechanical peeling of Cynanchum wilfordii Hemsley¡¯s raw root whereas 36 minutes in manual peeling and values of lightness showed more higher in manual peeling than in mechanical peeling. 2. Yield in combination of diamond shape¡¯s steel blade and sand abrasive showed the lowest at 89.9% among treatments and peeling rates in combination of diamond shape¡¯s steel blade and small pebble showed the highest at 71.3% in mechanical peeling. 3. Lightness, one of the most important factors in determining quality of Cynanchum wilfordii Hemsley, showed the highest in combination of diamond shape¡¯s steel blade and small pebble brasive at 61.90 in mechanical peeling. 4. As the speed of rotation gets faster, yields tend to lower in mechanical peeling. Peeling rates and lightness showed the highest at 66.8%, 57.96 respectively among treatments at 30 r.p.m. in mechanical peeling.
