Description

Technical Field

[0001] The utility model belongs to the technical field of yeast fermentation, in particular to yeast fermentation equipment. Background Art

[0002] Yeast is a facultative anaerobic microorganism. In the presence of oxygen, it undergoes aerobic respiration, breaking down sugars into carbon dioxide and water, releasing a large amount of energy. In the absence of oxygen, it undergoes anaerobic respiration (alcoholic fermentation), breaking down sugars into carbon dioxide and alcohol, releasing a small amount of energy. Yeast fermentation equipment provides a fermentation environment for yeast and is widely used in the food industry. Yeast ferments efficiently at optimal temperatures. Temperatures that are too high or too low are unsuitable for normal yeast growth and result in low fermentation efficiency. Both aerobic and anaerobic respiration release heat, so controlling the temperature within the fermentation tank to maintain the optimal fermentation temperature is crucial for improving fermentation efficiency.

[0003] A Chinese patent (CN211595609U) discloses a yeast fermentation device. In this technical solution, heat sinks are arranged at intervals within the fermentation tank. The heat sinks are provided with several heat dissipation holes, and a through-hole in the center is reserved for a stirring rod to pass through. The stirring rod stirs between the heat sinks, and the heat sinks transfer the heat in the fermentation tank to a cooling circulation tank for cooling. Although this patent can evenly absorb excess heat in the fermentation tank, the heat sinks are arranged vertically at intervals within the fermentation tank. Although several through-holes and a through-hole for the stirring rod are provided, the yeast and fermentation raw materials in the fermentation tank are still unevenly distributed, resulting in reduced fermentation efficiency.
