By adopting technologies for in-cabinet crushing of herbal pieces, high-efficiency delivery, and precise weighing of viscous pieces as well as light and bulky flower, leaf, and grass-type pieces, this solution achieves fully automated dispensing of all commonly used herbal pieces. It fundamentally solves the practical problems of traditional dispensing modes, including low efficiency, inaccurate weighing, dust contamination, high labor intensity for personnel, and high labor costs for enterprises, thereby realizing automated, intelligent, and unmanned management of traditional bulk herbal piece dispensing.
