牡蛎贝壳质地坚硬如石、以往煅制时,将药材砸成小块,置无烟炉火上或置适宜的容器,或铁锅内煅至酥脆红透时取出放凉碾碎。但此法煅制工艺繁锁,浪费工时,生产效率较低,由于温度过高,用具损坏或减少寿命。我们对火煅制方法,进行工艺操作方 The texture of oyster shells is as hard as stone. In the past, the medicinal materials were chopped into small pieces, placed on a smokeless fire or placed in a suitable container, or baked in an iron pan until crispy and red, and then taken out and let cool and crushed.

We carry out process operations on the fired method
