A method of decontaminating grain, nut, or seed products and a method for conditioning grain in a milling process for decontamination and to produce an improved milled product which will yield baked goods, for example, of increased size and extended shelf life. A first shaft portion and a second shaft portion rotatably support rotating plates bent and formed in the flaps and an insertion mouth is formed in the abutting surfaces of the flaps. It can communicate with trapped and injured persons inside the fire scene and can send back video and audio information describing the fire environment inside the building to the controller. Confidence for each document style is calculated based on the frozen pattern list and the detected style of the input document. When the status button is pressed and the status information exists in the memory, the transceiver device outputs the control signal and the status information stored in the memory. In case of data reading or data writing, a declared value management part checks parameters and a slot allocation part allocates the resource, thereby constructing an efficient file system guaranteeing delay quality in relation to data reading.
