Description

Technical Field

[0001] The utility model relates to a device for preparing a yeast culture for feeding, belonging to the field of yeast culture preparation. Background Art

[0002] Yeast culture is a fermentation product formed after yeast cells produce metabolic products under the control of a certain specific fermentation process. Adding yeast culture to feed during animal feeding is beneficial to regulating the balance of gastrointestinal flora in livestock and poultry. The fermenter is one of the main equipment for preparing yeast culture. In order to facilitate the uniform mixing of yeast culture raw materials in the fermenter, a motor needs to be installed on the top cover. The agitator installed on the motor output shaft extends into the fermenter. When the motor drives the agitator to rotate, the yeast culture raw materials in the fermenter are stirred and mixed. In order to improve the sealing between the motor output shaft and the top cover, a dynamic seal needs to be installed between the motor output shaft and the top cover. As the yeast culture raw materials ferment, the air pressure in the fermenter gradually increases. Under the action of the gradually increasing air pressure in the fermenter, the rotating part of the dynamic seal tends to move upward, so that the dynamic seal structure is easily damaged. Therefore, it is necessary to design a feed yeast culture preparation device that prevents the gradually increasing pressure in the fermenter from damaging the dynamic seal structure.
