Description

Technical Field

[0001] This utility model relates to the field of fermentation device preparation technology, and in particular to an intelligent constant temperature fermentation device. Background Technology

[0002] Fermentation is the process by which microorganisms convert organic matter into other substances under aerobic or anaerobic conditions. It is widely used in the manufacture of food, beverages, wine, biofuels, and industrial chemicals. Traditional fermentation equipment typically includes fermentation tanks, fermentation vessels, fermentation barrels, and fermentation tanks, but each has its own drawbacks: fermentation tanks are difficult to clean, hygiene is hard to guarantee, and their sealing is not as good as other fermentation containers; fermentation barrels are fragile, heavy, inconvenient to clean and move, and difficult to load and unload; fermentation barrels offer a poor user experience, especially in large-scale wineries, where high-end customers may be dissatisfied during visits, and there is a risk of excessive plasticizers, which may affect the quality of the wine; fermentation tanks are costly, difficult to move, and have low automation.

[0003] Traditional fermentation facilities are typically simple and only suitable for small-scale workshops, making it difficult to scale up production. Due to high labor costs and the inability to control fermentation temperature, these facilities are greatly affected by seasonal and ambient temperature changes, making continuous operation impossible. Therefore, products fermented using traditional methods often exhibit inconsistent quality and relatively low production efficiency.

[0004] Fermentation engineering, as a core component of bioengineering, is undergoing in-depth research into its mechanisms and control, aiming to improve efficiency and reduce costs. With technological advancements, the application of fermentation technology in fields such as medicine and environmental remediation is constantly expanding. However, existing automated intelligent control technologies for fermentation still have many aspects that require optimization. Utility Model Content
