Description Not Available
Sticklac obtained a􀄞er scraping the lac incrustations from mature lac stick of host trees and
converted into seedlac at lac processing industries for its further use in making lac-based value
added products. Sticklac converted into seedlac can be stored like grain, in gunny bag or metal
bin for longer period without much deterioration in the quality so that lac grower can sell
seedlac whenever they get remunerative price. Different profiles of the churning blade used to
increase the working surface area to the maximum possible extent and enhance the turbulence
during washing operation of sticklac in presence of water for quality seedlac without major
change in conventional churning mechanism of lac washing machine developed under small
scale lac processing unit. Minimum and maximum impurity content and color index in the
prepared seedlac with churning time 15 min and lac-water ratio 1:1, 1:2 and 1:3 determined
as 3.37, 3.87 and 4.76% and 7.33, 8.00 and 8.00 whereas with churning time 30 min 2.57, 2.64
and 4.00% and 6.00, 6.00 and 7.00, respectively which indicates that higher amount of water
increased impurity and color index, enhanced churning time reduced impurity content and
color index, while warm water reduced impurity level from 2.57 to 2.00%, 2.64 to 2.70% and
4.00 to 2.80% with churning time 30 min and lac-water ratio 1:1, 1:2 and 1:3, respectively but
color index was found higher (7.00) compared to normal water (6.00). Impurity content and
color index were lowest in seedlac (3.51% and 7.00) prepared using modified churning blade
‘rod parallel to the sha􀄞’ compared to other modified churning blade and conventional blade.
