Description

Technical Field

[0001] The utility model relates to the technical field of fermentation tanks, in particular to a fermentation tank which is convenient for producing yeast culture for fishery. Background Art

[0002] The fishery yeast culture fermentation tank is a device used to culture and ferment yeast, which simulates the growth environment and fermentation process of yeast in nature. In the fishery, this fermentation tank is often used to produce yeast protein for aquaculture. These yeasts can be brewer's yeast, baker's yeast, etc. They can convert sugars into proteins and other nutrient-rich biomass.

[0003] According to the search, the Chinese patent document, announcement number: CN217202758U, discloses a temperature-controlled and stable fermentation tank for processing fishery yeast culture. The fixing rod, the first scraper, the second scraper, the first slot and the second slot are used in combination to improve the stirring effect, and solve the problem that the culture near the inner wall of the fermentation tank is subjected to poor stirring effect during the stirring process of the existing fermentation tank stirring mechanism, which affects the normal processing. However, the device cannot effectively control the temperature inside the device during actual use, because the fermentation tank needs to be preheated before the fermentation starts to ensure the suitable growth temperature of the microorganisms. During the fermentation process, the metabolism of the microorganisms will generate heat, which may cause the temperature of the fermentation liquid to be too high, so it needs to be cooled in time; in addition, since yeast generally needs to be introduced with oxygen to accelerate the reproduction of the bacteria in the early stage of fermentation, and the device is not provided with a corresponding ventilation system to ensure sufficient oxygen supply, which reduces the overall practicality of the device. Utility Model Content

[0004] 1. Technical issues to be solved

[0014] Preferably, a spiral guide groove is provided inside the jacket, and the water inlet pipe and the water outlet pipe are both fixedly installed inside the spiral guide groove.

[0015] Through the above technical solution, the water inlet pipe and the water outlet pipe are connected to circulation equipment such as a water pump, a heater or a cooler, so that the hot fluid or the cold fluid can be effectively input into the interior of the spiral guide groove. When the fluid flows therein, the tank body can be effectively heated or cooled, so the internal temperature of the tank body can be effectively adjusted to maintain a suitable growth temperature for microorganisms, thereby ensuring the stability of the fermentation process.

[0016] Preferably, a sealing cover is hinged on the top surface of the feed pipe, and a second one-way valve is fixedly installed inside the exhaust pipe.

[0020] 2. The utility model starts the hollow shaft motor, and the output shaft of the hollow shaft motor can drive the rotating rod, the air pipe, the nozzle and multiple stirring blades to rotate together. Therefore, when the air is sprayed out from the multiple nozzles, it can be evenly distributed inside the tank body. The multiple stirring blades can not only increase the gas-liquid contact area and improve the oxygen transmission efficiency, but also proper stirring can activate microorganisms and promote faster growth and reproduction of microorganisms, thereby speeding up the speed of the entire fermentation process. By connecting the water inlet pipe and the water outlet pipe to circulation equipment such as a water pump, a heater or a cooler, hot fluid or cold fluid can be effectively input into the interior of the spiral guide groove.
