Description

Technical Field

[0001] The utility model belongs to the technical field of bread dough fermentation devices, and more specifically, it relates to a sourdough fermentation device for bread. Background Art

[0002] Dough fermentation, also known as leavening dough, refers to the process in which dough expands by allowing yeast to multiply and produce gas under certain temperature and humidity conditions. When yeast converts starch into sugar and consumes it in an aerobic environment inside the dough, carbon dioxide gas is released, causing the dough to expand in volume. The pasta made from fermented dough has a sweeter and softer texture. In the bread-making process, first, under certain conditions, the dough ferments to produce sourdough through the growth, reproduction, and metabolism of microorganisms. The quality of the fermented sourdough plays a crucial role in bread-making.

[0003] Dough fermentation is mostly carried out by placing the dough in a container, covering it with a film, and then putting it into a fermentation device. Most of the existing fermentation devices heat and evaporate the water in the water tank in the fermentation chamber by electric heating tubes, or directly install a heating device at the bottom of the fermentation chamber to heat the dough, enabling it to ferment and expand fully at a certain temperature and humidity. The heating of the dough in the existing fermentation devices is local heating at the bottom, which will cause uneven heating of the dough circumference, thus affecting the fermentation time and quality of the dough. Content of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the present utility model is to provide a sourdough fermentation device for bread, which has the advantages of enabling the dough to be evenly heated and accelerating the dough fermentation.

[0016] The advantages of this solution are at least as follows: when the temperature and pH value are too high, the temperature is first reduced by opening the water inlet and the feeding port, and flour and water are added into the fermentation chamber through the feeding port and the water inlet to ensure that the temperature and pH value in the fermentation chamber are at the specified values.

[0017] The present utility model is further configured such that: two handles are installed on the sealing cover, and a flexible member is wound around the outer surface of the handle.

[0018] The advantages of this solution are at least as follows: when opening the sealing cover, the handle facilitates the taking of the sealing cover, and the function of the flexible member can increase the comfort between the handle and the palm, and at the same time avoid the occurrence of hand slipping.

[0019] In summary, the present utility model has at least the following advantages:

[0020] 1.
