Description

Technical Field

[0001] This utility model relates to the field of fermentation, and in particular to an automated anaerobic yeast fermenter. Background Technology

[0002] An anaerobic yeast fermenter is a specialized device that provides an oxygen-free, sealed environment for yeast to carry out efficient alcoholic fermentation. Its core function is to encourage yeast to convert sugars into ethanol, carbon dioxide, and flavor compounds, rather than allowing them to multiply under oxygen. Its advantages include effectively preventing contamination by other microorganisms and oxidative spoilage, thus ensuring product quality and flavor. By precisely controlling parameters such as temperature, it significantly improves fermentation efficiency and stability, while also facilitating automated large-scale production and ensuring safety and cleanliness. Common automated anaerobic yeast fermenters often rely solely on a single rotating agitator for stirring. However, simple stirring often fails to evenly distribute the fermentation liquid, easily leading to uneven temperatures and affecting fermentation efficiency and quality. Therefore, an automated anaerobic yeast fermenter is needed.

[0003] Existing automated anaerobic yeast fermenters often rely solely on a single agitator for stirring during operation. However, this single agitation method often fails to ensure uniform mixing of the fermentation broth, leading to uneven temperatures throughout the fermentation process and impacting fermentation efficiency and quality. Furthermore, relying on a single temperature control pipe and insulation material for temperature control and insulation of the fermenter often fails to guarantee the timeliness of temperature changes or the durability of insulation.

[0004] To address the aforementioned issues, a search revealed a patent with publication number CN214881365U, which discloses a yeast fermentation tank. The patent states: "1. The tank contains brewing yeast for fermentation. A stirring shaft stirs the yeast within the tank to improve fermentation efficiency. A medium at a certain temperature is continuously poured into the tank through the inlet hose. The medium flows through the stirring shaft and blades, then exits the tank through the outlet hose, thereby regulating the temperature within the tank to make it more suitable for brewing yeast fermentation and improving the fermentation effect. 2. The stirring shaft drives the upper and lower spiral blades to rotate in opposite directions, which simultaneously stirs the brewing yeast within the tank and tumbles it up and down under the action of the spiral blades, thus improving fermentation efficiency." While this combination of forward and reverse stirring with opposing spiral blades can effectively improve material mixing uniformity, prevent sedimentation, and promote fermentation efficiency, frequent switching between forward and reverse rotation may increase the load on the servo motor, affecting long-term stability.

[0005] In light of this, in-depth research into the aforementioned issues led to the creation of this case. Utility Model Content

[0006] The purpose of this invention is to provide an automated anaerobic yeast fermenter to solve the problems mentioned in the background art. In the process of using existing automated anaerobic yeast fermenters, they often only use a single stirrer for rotation and stirring. However, single stirring often cannot mix the fermentation liquid evenly, which can easily cause uneven temperature in the fermentation liquid, affecting fermentation efficiency and quality. In addition, temperature control and heat preservation of the fermenter by a single temperature control pipe and heat preservation material often cannot ensure the timeliness of temperature changes and the durability of heat preservation.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an automated anaerobic yeast fermentation tank, comprising a support leg, a support ring fixedly installed on the upper surface of the support leg, a tank body fixedly installed on the inner surface of the support ring, a vacuum insulation chamber sleeved on the outer surface of the tank body, a hot water pipe abutting against the outer surface of the tank body, a cold water pipe abutting against the outer surface of the tank body, a support frame fixedly installed on the upper surface of the tank body, a motor fixedly installed at the upper mounting groove of the support frame, a square column fixedly installed at the output end of the motor, a rotating shaft sleeved on the outer surface of the square column, a first protruding post fixedly installed on the upper outer surface of the rotating shaft, a first ball bearing placed in a mounting groove on one side of the first protruding post, a first set of columns fixedly installed on the upper surface of the tank body, a second protruding post fixedly installed on the lower outer surface of the rotating shaft, a second ball bearing placed in a mounting groove at one end of the second protruding post, a second set of columns fixedly installed on the inner bottom surface of the tank body, and a stirring blade fixedly installed on the outer surface of the rotating shaft.

The track structure inside the first and second sets of columns can realize the compound motion of the rotating shaft (rotation + up and down movement). The first and second ball bearings can greatly reduce the frictional resistance during the up and down movement of the rotating shaft, ensuring smooth and reliable movement, enabling the stirring blades to mix the materials more thoroughly, eliminating stirring dead zones, and significantly improving fermentation efficiency and quality.
