Description

Technical Field

[0001] This utility model relates to the field of proofing box technology, specifically a proofing box for a hot air circulating oven. Background Technology

[0002] As a core piece of equipment in pasta processing and baking, the proofing box provides a suitable temperature and humidity environment for the dough, promotes yeast fermentation, and ensures the consistency of the taste, fluffiness, and appearance of the finished pasta products.

[0003] According to patent document CN221962728U, a proofing box with tray height adjustment function is disclosed, including a box body, with partitions inside the box body, connecting seats installed on both sides of the partitions, gears located inside the connecting seats, and a motor installed on the surface of the connecting seats, with the motor connected to the gears. This utility model overcomes the shortcomings of the prior art. This utility model employs connecting seats, a motor, gears, and an adjusting rod. Connecting seats are connected to both sides of the partitions, and a motor is installed on the surface of the connecting seats. The motor is connected to the gear inside the connecting seat, and the gear meshes with one side of the adjusting rod. When it is necessary to adjust the distance between the partitions, the operation of the motor causes the gear to rotate. After the gear rotates, the adjusting rod can be moved up and down to adjust the distance between the partitions.

[0004] However, existing proofing boxes have key technical pain points: uneven temperature and humidity distribution. Due to unreasonable air duct design and poor air circulation path, local high temperature and high humidity or low temperature and low humidity areas are easily formed inside the box. This leads to significant differences in the fermentation speed of dough in different locations. Some dough is over-fermented and develops a honeycomb structure, while some is under-fermented and the finished product is stiff, which seriously affects the stability of product quality. At the same time, the uneven temperature and humidity environment will also reduce the utilization rate of yeast activity, prolong the overall proofing time, and restrict production efficiency. Summary of the Invention
