Britannia-in addition to being a flashy title for Britain, as in Britannia Rules the Waves, it is also a trade name for a series of machines invented by the young inventor William Jackson in the 1870s.

His tea mill was the main innovation that directly changed all aspects of tea production in Assam. In terms of production and consumption, it has shifted the global market from Chinese green tea to Indian black tea.

This is not only historic, because it solves the core problems of the development of the tea industry in the past 150 years and in the foreseeable future: (1) machines replace labour (such as mass market bags and mixtures), (2) machine utilization of labour, (mid-range whole leaves) (3) machines are superior to labour (vacuum packaging and storage) (4) machines reduce labor (quality varieties of tea).

There are three main links in the process of making tea: picking in the tea field, processing in the factory, and distributor distribution.

With the emergence of mechanization, the quality and variety of some of these production stages have been greatly reduced.

This is especially true when pulling leaves from shrubs. The difference between "two leaves and one bud" orange and white and machine picking is equivalent to catching and preparing fresh wild Pacific salmon and farm-raised frozen tilapia. This is the contrast between machine and manual labor.

Similarly, in terms of packaging tea, the warehouse storage and vacuum packaging of fresh tea are completely superior to the treatment of tea, just like a shovel of mulch. Here, machines are superior to human labor.
