Description

Technical Field

[0001] This utility model relates to the field of fermentation technology, and more specifically, to a fermentation device for preparing peach blossom rice wine. Background Technology

[0002] During fermentation, the raw materials for peach blossom rice wine (such as rice, yeast, and water) undergo a fermentation reaction, producing a large amount of alcohol and carbon dioxide. This process not only releases a significant amount of heat but may also produce some viscous substances, especially rice paste, which easily adheres to the bottom and inner wall of the fermentation tank. During fermentation, rice grains mix with water to form rice paste. After fermentation, the combination of rice paste and yeast residue causes it to adhere to the bottom and walls of the tank. If not cleaned promptly, these residues will affect the quality of the next fermentation. During fermentation, some sugars and other reaction products may also form deposits on the tank walls. The accumulation of these substances not only affects the flavor of the rice wine but may also lead to a reduction in fermentation efficiency.

[0003] During fermentation, constant stirring is necessary to promote even distribution of yeast and facilitate the fermentation reaction. However, during stirring, hard objects, incompletely fermented rice grains, or impurities may be encountered in the tank. The presence of these hard objects can negatively impact the stirring process. As the stirrer rotates, it encounters unsoftened rice grains or other hard objects, increasing the load on the stirrer. If this situation persists, the stirrer shaft will experience excessive pressure, leading to overload. Prolonged overload can damage the motor or cause equipment malfunction. The presence of hard objects hinders the normal operation of the stirrer, resulting in uneven mixing of yeast and rice grains, thus reducing the effectiveness of the fermentation reaction. Some rice grains may not ferment fully, leading to unstable rice wine quality and poor taste. Prolonged overload of the shaft can damage the motor, deform the stirrer, or even cause it to fail completely, affecting production efficiency. Utility Model Content
