PROBLEM TO BE SOLVED: To provide a not-big, compactified and space-saving device capable of achieving a high energy-efficiency and time-shortening, as well as continuous grinding, drying and collecting of powder/particle-like food.SOLUTION: A drying and grinding device for manufacturing powder/particle-like food has: a container 11 of objects to be ground, with mesh like regions which are passable by powder/particle bodies at lateral and bottom surfaces a relevant objects feed portion 12 arranged above the container 11 a heat and wind feed mechanism 13 to the container 11 a grind means 14 grinding the relevant objects 20 in the container 11 a wall face portion 15 which leads the powder/particle bodies scattering outwards from the container 11 downwards and a powder/particle body container 16. Here, the container 11 divides one space from an upper surface to a bottom surface into two or more zones to include the division parts 11a1 to 11a4 whose diameter is formed to lessen toward a bottom side of the container 11, while the grind means 14 has a rotation cutter 14a which cuts the relevant objects 20 existing in the respective spatial zones of the container 11 into the sizes which can pass through the division parts concerned, the meshes of the bottom or the lateral surface of the container 11 at different speeds, respectively.COPYRIGHT: (C)2013,JPO&INPIT【課題】大掛かりにならず、小型化、省スペース化でき、エネルギー効率良く、時間を短縮し、且つ、継続的に粉砕・乾燥・回収できる装置の提供。【解決手段】側面及び底面に粉粒体を通過可能な網目状領域を有する被粉砕物収容器11、収容器11の上方に配置された被粉砕物供給部12、収容器11への熱・風供給機構13、収容器11内の被粉砕物20を粉砕する手段14、収容器11の外部に飛散する粉粒体を下方に導く壁面部15、粉粒体収容部16を有し、収容器11は、上面から底面に至るまでの一つの空間を複数に区画し、収容器11の底面側ほど細径に形成された区画部11a1~11a4を備え、粉砕手段14は、収容器11の夫々の空間に位置する被粉砕物20を当該空間の下方の当該区画部、収容器11の底面又は側面の網目を通過可能な大きさに、夫々異なる回転速度で切断する回転カッター14aからなる。【選択図】図1
