一、去皮:传统的刮皮法工效低,且操作时用力不匀,常有刮去药用部位浪费药材的现象。同时纵裂槽纹中的粗皮和绿苔不易刮去。改进后采用刷皮法:先将杜仲刷洗干净,润透后,用钢丝刷纵横各刷一次,粗皮即可全部脱落,同时纵裂槽纹中的粗皮、绿苔也能一次去净。此法省工省时,亦可用于海桐皮、厚朴等皮类药材的加工。二、切制:传统的骨牌块片切制工序烦琐,在切片时,须先切成条状后,再切成块。并且,块片在炒制时受热不匀,不易达到断丝要求。笔者将块片改为丝片,即将去粗皮润好后的杜仲切6毫米左右丝片。笔者曾多次作过试验,丝片和块片,在同一条件下烫制,块片烫27分钟才能达到断丝要求,
I. Peeling: The traditional squeegeeing method has low ergonomics, and the force is uneven during operation, and often the phenomenon of waste of medicinal materials is scraped off from the medicinal site. At the same time, the rough skin and green moss in longitudinal slits are not easy to scrape off. After the improvement, the method of brushing skin is adopted: First, the Eucommia ulmoides should be brushed cleanly and thoroughly. After brushing, the brush can be brushed vertically and horizontally with a wire brush. The rough skin can be completely detached, and the rough skin and green moss in the longitudinal crack flutes can also be removed once. This method saves time and labor, can also be used for Pittosporum, Magnolia and other leather medicine processing. Second, cut: the traditional domino pieces cutting process cumbersome, in the section, you must first cut into strips, and then cut into pieces. In addition, the pieces are heated unevenly during the frying process, and it is not easy to meet the broken wire requirements. The author changed the piece into a silk piece, about to cut the 6mm silk piece of the Eucommia ulmoides after the rough skin was moistened. The author has repeatedly tried, silk and pieces, under the same conditions, hot, block pieces of hot 27 minutes to meet the broken wire requirements,
