目前各地规范及一些炮制书籍均主张采用干切或洗后切两种方法切制地龙。我们在实践中发现以上两法均存在不少缺点:干切地龙灰尘大,腥味浓,呛鼻,刺喉,刀口容易磨损。洗后切制,若快洗则地龙体内的泥灰去不净;若慢洗则地龙浸水后易变软起粘,而且极难晾干。洗后上机切制过程中,由于链条的挤压,往往将地龙体内未去净的污泥挤出表面,形成粘糊状,从而糊住链条孔,开机后易使链条打滑,给切制造成困难。
At present, local standards and some concocted books advocate the use of dry cutting or washing and cutting to cut ground dragons. In practice, we found that both of the above two methods have many shortcomings: dry ground dust, large dust, strong smell, blowing nose, piercing the throat, the knife edge is easy to wear. After washing and cutting, if you quickly wash, the mud in the dragon’s body will not go to the net; if you wash slowly, the dragon will become soft and sticky after soaking in water, and it is extremely difficult to dry. In the process of cutting machine after washing, due to the extrusion of the chain, the mud that is not to be netted in the earthworm body is often squeezed out of the surface to form a sticky paste, thereby sticking the chain hole, and the chain is easily slippery after being started, and the chain is cut. Made difficult.
