| 摘要 |
The present invention relates to a device for detecting the raising state of small piles of dough (11) submitted to a fermentation process which is for example induced by yeast in a raising chamber and during which the volume of said piles increases. The device includes at least one variance detector (21 ) which is associated with at least one of the piles of dough placed in the raising chamber, and which generates a characteristic output signal when the thickness of the dough reaches a predetermined target value corresponding to a desired maturation degree of the dough. The variance detector (21) consists of an ultrasound detector for measuring the propagation time of the ultrasound signals. The detector is placed on a tripod (17) which can be arranged in th e raising chamber (13) on the bottom thereof.
