The invention discloses a heating device of a dough fermenting device. When fermenting, the controller sequentially and individually opens the electromagnetic control valves so as to intermittently ventilate the airflow at each ventilation hood, and As the fermentation time increases, the opening time of each electromagnetic control valve gradually decreases, so as to shorten the ventilation time as the fermentation progresses. In this way, in the initial fermentation, the ventilation volume is large and the oxygen is sufficient, so that a faster fermentation can be achieved. , and at the end of fermentation, there is less ventilation, and the control of the amount of internal oxygen can slow down the continuous fermentation, reduce the performance of the over-fermentation of the dough taken out, and ensure the fermentation capacity. The amount of air exchange is controlled, and the air exchange is uniform to achieve uniform fermentation.

The invention discloses a torsional vibration energy storage and release device. The torsional vibration energy storage and release device comprises a transmission shaft. The left end and the right end of the transmission shaft are rotationally connected to bearing blocks through rolling bearings respectively. A bearing end cover for limiting the position of each rolling bearing is fixed to the corresponding bearing block. A push mechanism is arranged at the bottom of each bearing block. A pressure plate is fixed to the middle of the transmission shaft. In conclusion, the torsional vibration energy storage and release device can achieve the effective damping effect on a system on one hand, and is mainly used for conversion between self-excited vibration and forced vibration in a vibrationtest platform on the other hand; when forced vibration happens to the system, the micro-amplitude torsional vibration energy of the system is collected by the device; and after forced vibration stops,because of a clutch structure, the collected energy is released inside the system, and the experimental system can have own self-excited torsional vibration.

The invention relates to the technical field of stamping of new materials, and discloses a stamping device for stamping a novel ceramic material, which includes a bracket overall, and the bracket is generally fixed with a driving device, and the driving device includes a guide cylinder and a telescopic column.
