Roll breaking process of tea manufacturing

Roll breaking is the next step of tea manufacturing after the rolling process. In the process of roll breaking, rolled tea leaves which is called as ‘Dhool’ will be separated depending on the particle size.

Different machineries are used for this roll breaking process. These machines are different types of sifters. Almost all the machines are made with different mesh sizes attached to a wooden or steel frame. These mesh sizes are organized as a series where the size is in increasing order or decreasing order. In this step, dhools derived from the rollers will be loaded to the first tray of the roll breaking machine and let the particles to strain from the mesh to be collected to a container. Then the remaining particles in the tray will be charge to the second tray with larger mesh than the first tray and repeat the same.

These different size particles will be subjected to the fermentation separately. This is the beginning of deriving different tea grades depending on the particle size. The remaining large particle in the last tray called ‘big bulk’. These particles can be sent to the rolling process again or will ferment and dry them to resize them into small particles using tea cutters.≈

During the roll breaking process fermentation of this rolled tea is continued as started in rolling process. Because of that it is very important to control the roll breaking time properly for preserving the final quality of the tea.

There are mainly two types of orthodox tea grade series as leafy grades and dust type tea grades in addition to special grades and extra special tea grades. Roll braking is a common process in all kind of these mentioned grades. Machinery types can be differing according to the desired grade. It is important to have skilled and experienced worker in this process is critical in obtaining quality tea as a final product since the degree of fermentation depend on it.
