TASTE RECOGNIZING AND DECIDING DEVICE

摘要

PURPOSE: To make it possible to prevent the dissolution of a specimen material contg. a taste material into a washing liquid during the course of feeding by surely classifying the specimen material and the washing material even when the supply passage of a taste recognizing and deciding device is set long. CONSTITUTION: The supply passage 3 is led out of a stimulus imparting device 1. The end of the supply passage 3 is provided with a mouthpiece device 5 and a stimulus sensor 4. The stimulus imparting device 1 has a first route R1 for feeding the specimen material 6, a second route R2 for feeding the washing liquid 7 and a third route R3 for feeding pressurized air 8. The respective routes R1 to R3 and the supply route 3 are connected by a valve device 9 so that the specimen material 6, the washing liquid 7 and the pressurized air 8 are delivered selectively to the supply passage 3. The pressurized air 8 is positioned between the specimen material 6 and the washing liquid 7 within the supply passage 3 to prevent the dissolution of the specimen material 6.
