Claims7
A process for the production of a menthol pastille with a curved side and a flat side, comprising the step of:
- placing a pre-scraped melt of menthol compounds with added seed crystals of L-menthol onto a pre-cooled single steel belt by even deposition of drops, and wherein the steel belt has cooling zones independently of one another each having a temperature below the respective melting point of said L-menthol seed crystals in the range of from about 15 to about 42° C.
