Lac is a natural resin having wide applications ranging from surface coating to synthesis of
fine chemicals. The basic raw material for lac industry is stick lac, which is used for making
seed lac, shellac, bleached lac and other value added products. Drying is an important unit
operation in preparation of these semi-refined and finished products. The most important
parameter in drying of lac is drying temperature, which should be kept below its softening
temperature (40-50°C) during drying operation. The various lac processing units fall into
two categories, namely non-mechanized and mechanized units. In non-mechanized
unitsdrying is carried out either in mild sun-light or in shade manually employing labour;
whereas in mechanized units, the drying operation is mechanized to some extent for seed
lac, but for products like bleached lac and other value added products, proper drying is still
a tough task. The paper discusses the drying requirements for different lac products like
stick lac, seed lac, bleached lac, aleuritic acid, lac dye and extent of mechanization of this
operation and scope of improvement in it.
