[0018] A method for using a bread processing fabric fermentation device, the specific contents are as follows:

[0019] S1, installing the trays on the first tray rack and the second tray rack respectively through the installation components, and then evenly placing the weighed bread dough on the trays;

[0020] S2, after placement is completed, start the driving member, which drives the sprocket to rotate through the transmission member, and then drives the sprocket to drive the chain to rotate. The chain drives the first tray rack to slide in the fermentation box through the connecting block. The height of the first tray rack is adjusted according to actual needs to move the first tray rack to a suitable position;

[0021] S3, close the fermentation box and start the fermentation operation of the bread fabric. After the fermentation is completed, open the fermentation box and start the reverse drive of the same way as above, so that the three first tray racks at the upper end move downward. When the first tray rack at the lower end moves above the second tray rack, as the first tray rack continues to move downward, the support column slides upward against the slide until the gravity sensor contacts the inner wall of the upper end of the third storage chamber. The gravity sensor value changes, causing the rotating motor to rotate in the opposite direction, and the ball screw rotates synchronously with the rotation direction of the rotating motor. The two wire sleeves approach each other, causing the clamping column to disengage from the clamping port. At this time, the lowermost first tray rack is placed on the second tray rack, and so on. The three first tray racks are stacked in sequence to lower the height of the three first tray racks, and then the fermented fabrics are taken out.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] The present invention can accurately and stably drive the chain to rotate through the transmission system composed of the adjustment components, thereby driving the connecting block and the first tray rack to slide in the fermentation box. The operator does not need to climb to a high place to place the fabric. He only needs to start the drive motor to flexibly adjust the height of the first tray rack according to needs. For example, when the fabric needs to be placed, the first tray rack can be adjusted to a suitable lower position, which makes it convenient for the operator to easily place the fabric on the tray, greatly reducing the difficulty of operation. During the placement process, since the first tray rack is in a lower and stable position, the risk of the bracket tilting caused by climbing in the traditional method is avoided, and the fabric is effectively prevented from moving or falling, which significantly improves the operation efficiency and safety. Through structures such as the support column, the slide plate, the gravity sensor and the reset spring, multiple first tray racks are automatically placed and stacked after fermentation is completed. This automated operation does not require manual disassembly and stacking of the tray racks, saving manpower and time costs. When the first tray rack needs to be reset later, the cooperation of the laser rangefinder and the sensor plate can accurately control the first tray rack to return to its initial position, ensuring the convenience and accuracy of the device operation.

[0024] The first storage cavity opened on the first tray rack and the second tray rack of the present invention provides a precise installation and positioning space for the tray. The tray can be firmly installed on the first tray rack and the second tray rack through the cooperation of the fixing plate, the threaded groove and the fastening bolt, and it also facilitates the disassembly of the tray and the regular cleaning of the tray. The Formosa wheel installed at the bottom of the fermentation box gives the entire device flexible mobility. In the bread processing workshop, the fermentation box can be easily pushed to the designated position according to the adjustment of the production layout, equipment maintenance or different production needs, without the help of other handling equipment, which greatly improves the convenience of use of the device.
