Abstract

The force analysis of the tea leaves on the U-shaped tank of the resistance wire heating groove-type tea de-enzyming and carding machine is conducted, and then the track analysis on SolidWorks based on the force analysis. The coupled steady state thermal analysis is carried out on the heating tank of the two kinds of machinery. The comparative test and content analysis of the three prototypes and gas trough machines are conducted, and the average value of the three tests is considered. The results are presented. The output of the prototype is 3.80 kg h-1, the strip rate is 88.38%, and the surface temperature of the pot groove reaches the requirement of finishing temperature.

Abstract in Chinese

对茶叶在电阻丝加热-槽式杀青理条机的U型锅槽的进行受力分析，然后基于受力分析对茶叶在solidworks上进行轨迹分析，得到茶叶在U型锅槽上的轨迹分析图,了解茶叶在机械杀青锅槽中主要的受热位置。对燃气式槽式杀青理条机与电阻丝-槽式杀青理条机的加热时的锅槽,分别进行耦合稳态热分析。进行三组样机与燃气式槽式杀青机的对比试验以及内含物分析，皆取3次试验结果的平均值；结果表明。电阻丝-槽式杀青理条机台时产量为3.80 kg/h，成条率为88.38%，锅槽表面温度达到杀青温度要求。
