摘要：
本发明的粉体供给装置（1），是将供料罐（11）内的粉体经由供料罐（11）的下游的粉体用阀（21）而从粉体输送配管（31）供给的粉体供给装置，具备：粉体流动化部（54），设置于供料罐（11），导入使粉体流动化的流动化气体；以及粉体再流动化部（57），设置在粉体流动化部（54）与粉体用阀（21）之间，导入使粉体再流动化的再流动化气体。本发明由于该特征而能够稳定地供给粉体。关于粉体供给方法也是同样的。
摘要（英）：

A powder supply apparatus (1) of the present invention supplies a powder in a feed tank (11) from powder transport piping (31) via a valve (21) for the powder, said valve being in the downstream of the feed tank (11). The powder supply apparatus is characterized in being provided with: a powder fluidizing unit (54), which is provided on the feed tank (11), and which introduces a fluidizing gas that fluidizes the powder; and a powder re-fluidizing unit (57), which is provided between the powder fluidizing unit (54) and the valve (21) for the powder, and which introduces a re-fluidizing gas that re-fluidizes the powder. With such features, this invention is capable of stably supplying the powder. A powder supply method of the present invention has same features.
