PURPOSE:To simplify a check of secular change in the processed material by installing each of material housing bodies being horizontally shiftable and having an upward opening, in the frame body partitioned off in plural stages, and making one of these housing bodies so as to be opposed to a downward material discharge port all the time. CONSTITUTION:Only a housing body 7a at the lowermost stage is opposed to a material discharge port 5, housing the specified amount of work materials. Next, a housing body 7b at the next stage is opposed to the material discharge port 5, housing the work material as well. Likewise, the work material is housed in a housing body 7c. With this constitution, the secular change of the material processed under the specified condition is simply checkable. |
