Cleaning and grading are the first and most important post harvest operatino undertaken to remove foreign and undesirable material from the senna/pods and to separate the stem into various fraction. These great factors depend upon pharmaceuticals company(Prime number 1,2,3,4 and 5).

We also have machinery for cleaning of leaves as follows :

Winnower: By this method using powerful fans the same effect is created that of the winnowing in the fields by which the foreign matters are removed from the leaves which enter into the stock at the collection and leaves picking stage. The pre-cleaned leaves along with stems of equal weight are also then fed into the graders.

Grader: There are different graders which grades the leaves as per the size specified and by which method even pods are separated. The thick and thin stems are also separated.

The leaves are fed again into the winnowers if required and completely pure leaves attained by removing even tiny stems as per customer's specification which are bagged or pressed as bales and stitched ready for export from our plant.
