Recognize Of The Ancient Distiller

Since the 1950 s,a number of distillers have been unearthed,including the eastern Han dynasty distillers collected by Shanghai museum,the xinmang period distillers unearthed from zhangjiabao,Qinglong county,Hebei province,the Han dynasty distillers unearthed from tianchang county,Anhui province and the tomb of haihou,which provide excellent materials for the study of ancient distillers.Based on archaeological data and related documents,this paper makes a comparative study on distillers in different times.In order to find out their relationship and development,this paper compares and analyzes the dimensions,structure,cooler,cooling method and collection method.A few distiller size difference is not big,is the upper and lower nested structure;The upper split part is a retort or a cylindrical device,the lower split part is mostly a kettle or a structure similar to the kettle,a grate is arranged in the middle of the sleeving device,and the grate is provided with holes;Has a collecting groove and a flow port;Several objects cooler are pot type;From Han dynasty to Jin dynasty,the condensation of these distillers developed from air condensation to cold water condensation,and the effect of cold water condensation was much better than air condensation.From Han dynasty to Jin dynasty,although there are differences in the condensing methods of distillers in China,the external bearing method is adopted.its application makes distillers more perfect and more efficient.We speculate that the external bearing method is the technical basis of distillation in the true sense.Through comparative study,it is considered that these distillers are of the same origin in structure: they are composed of kettle body part,retort body part,condensing part and collecting part.China’s distiller is independent origin,self-contained.The fineness of distillers corresponds to the burial level,and the distillers unearthed from the high-grade tombs are better made and more efficient in distillation.The origin of distillation technology in ancient China and the west was discussed.it was considered that the origin of distillation technology in Arab and ancient Egypt was different from that in China,and the development of distillation technology was also different.the emergence time of distillation technology was later than that in China.Whether the western distillation technology can be used for reference to China needs further research.The ancient distillers borrowed from the upper and lower nested structure of ancient split copper steamer,and the ancient process of sand extraction and mercury smelting accumulated a lot of knowledge about evaporation and condensation.these two parts provide structural and technical references for the appearance of distillers in Han dynasty.After recognize and classification of bronze flow Yan,combing the kettle with flow Yan shape set of machine device in Han dynasty,we find their common characters: the times are Han dynasty;The device type are sleeved up and down;The kettle with flow,flow mouth down.Analysis of the aristocratic society at that time,a surge in demand,resulting in changes in the location of the flow,so that the structure and function of objects have changed.Lower kettle with flow of the steamer is still a boiler,the upper kettle set flow of split steamer has distillation function and lose the properties of the steamer,so this kind of called the steamer,the Han dynasty appeared this kind of steamer is the original distiller.
