A M.S. Drum furnace is utilized for carbonization of shells. The drum comprises of three arrangements of six 1" dia gaps gave at its base, center and upper layers and a cover. A separable smokestack is given which is introduced on the cover in the wake of shutting the drum. The produce of charcoal requires ideal carbonization of crude shells in a restricted supply of air so that there is neither unburnt shell nor powder because of finish ignition.
The steel drum is loaded with crude shells in the wake of putting briefly a four inch breadth wooden shaft in the focal point of the drum. The wooden post is then expelled, leaving an empty space in the inside which permits the stream of smoke amid carbonization.
To begin carbonization, a bit of consuming cloth is dropped to the base of the drum through the empty space in the inside. At the point when the fire is well in progress, the cover with the stack is set into position and the upper and the center arrangements of openings are shut. Carbonization which begins at the base advances as it goes up and in addition radially from the empty space.
At the point when carbonization is finished in a specific zone, a constant shine can be found in all the six gaps of a set.
At the point when the base most arrangement of gaps show this circumstance, the center arrangement of gaps is opened and the base set shut.
The stoppage of air streaming into the base district keeps away from over-carbonization in that locale. The dynamic carbonization brings about decrease in volume of substance and in this manner more shells are included from the best. At the point when the center district is carbonized well, the best arrangement of openings is opened while the center set is currently shut. A further expansion of crude shells is done to completely fill the volume lessening for consuming.
At the point when the best district is all around carbonized, the best arrangement of openings is additionally shut, bringing about entire stoppage of air inflow to the drum. The drum is then cooled for around eight hours after which the item is prepared for release.
