Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of dough processing, in particular to a dough pretreatment device for low GI noodle production. BACKGROUND

[0002] In the industrialized production process of noodles, the fermentation (proofing) of dough is a key link that determines the quality of the final product. However, when faced with mass production requirements, the traditional method of uniform fermentation using large-volume dough always has two major technical bottlenecks that are difficult to overcome: First, the structural problem: the self-weight of the dough inhibits uniform expansion. As the volume of the dough increases, its own weight increases significantly. The dough at the bottom and center is subjected to a huge pressure, and the gluten network is physically extruded and cannot expand freely like the upper and outer dough. This leads to uneven internal structure of the fermented dough, with dense organization at the bottom, which seriously affects the taste and quality of the finished product.

[0003] Second, the thermodynamic problem: temperature difference inside and outside leads to asynchronous fermentation. The fermentation process is accompanied by heat production, and it is difficult for the internal heat of large-volume dough to dissipate, forming a temperature gradient of "internal heat and external cold". This leads to excessive activity of internal yeast and even spoilage, while the activity of external yeast is insufficient, causing serious differences in fermentation state.

[0004] To avoid the above problems, the current industrial practice generally adopts the "divided dough fermentation" strategy, that is, the large dough is divided into multiple independent small doughs for separate processing. However, this method introduces new variation factors: the micro-environment (such as temperature and humidity) of numerous small doughs has unavoidable slight differences, leading to uneven fermentation quality within the batch, and unable to achieve truly stable, uniform and high-quality production.

[0013] As a preferred solution, the height of the overflow opening is consistent with the height of the elastic bottom film body, and when the elastic bottom film body is extruded by the dough fermentation, the constant temperature water is extruded and flows out from the overflow opening.

[0014] Compared with the prior art, the present application has the following advantages: 1.
