At JT&Tea, we use this pilot blender for staff training, and our tea blending workshops.
It is "old school", but it works well. The teas can be evenly blended, especially when working on the related materials that have very different sizes and densities.
You need to see it to believe it!
This should intrigue your imagination when creating new blends.
(As a side note, divide the recipe in 4 to have four rounds to complete a batch.)
Dr. Liu has experimented with three different teas: one green, one black, and one oolong, all in different sizes.
What is the result?
A scientist was convinced by this very traditional blending skill.
