Re-grading & Tipping
As a professional processor we know the importance of leaf position on stalk and how it impacts blend and subsequently customer’s end product. Chemical and physical properties of each group of leaves (lugs, cutters, leaf, and tips) are different so they are treated separately in processing.
Once tobacco is reached to processing facilities, for accuracy and to ensure the quality is uniform throughout the blend, tobacco is re-graded manually according to customer specifications.
Non Tobacco Related Materials (NTRM) Not only accuracy, re-grading is the most effective way and critical point to eliminate all NTRM by conducting visual inspection prior to processing. Farm environment is the primary sources of NTRM.
This process is optional based leaf density and customer requirement.
Re-graded tobacco in small bunch form is straight laid on moving belts for series of threshing operations. The leaves contain thin stems are cut up to the extent where the stem diameter confines to the specified objectionable stem size (usually (3/32)" diameter). Mechanically driven knives cut the leaves into two parts as tips and butts which are carried away by separate conveyers. The tips generally bypass the threshing operation and join the lamina emanating from the threshing operation. Blending of different grades of tobaccos can also be done conveniently on the tipping table as per the requirement.
