Description

Technical Field

[0001] The utility model relates to the field of fungus fermentation equipment, in particular to a triple fermentation device. Background Art

[0002] At present, some fungi are often added to livestock feed to improve the production performance and health level of animals. Common added bacteria include lactic acid bacteria, yeast, bifidobacterium, bacillus, etc. These fungi play an important role in feed, such as promoting the digestion and absorption of nutrients, improving the balance of intestinal microecology, and improving the body's immunity. At the same time, these fungi can also inhibit the growth of harmful bacteria and reduce the occurrence of diseases, thereby improving the health level of animals. It should be noted that the amount and type of fungi added need to be selected and adjusted according to factors such as the growth stage, health status, and feed type of the animal to ensure the best effect.

[0003] In livestock feed production, in order to obtain a sufficient amount of bacterial strains, the strains need to be cultured on a large scale in the factory; according to the characteristics of the strains and product requirements, select appropriate fermentation equipment, such as culture tanks, fermentation tanks or bioreactors; according to the needs of the strains, prepare an appropriate amount of fermentation medium according to the formula, and perform aseptic operations in the fermentation equipment; transfer the strains that have undergone primary culture to large-scale culture medium to culture the strains in larger containers. However, most of the current strains are secondary cultures. After being transferred from small containers to large containers, the strains are prone to uneven distribution and inconsistent growth rates, which affect the growth and reproduction of the strains; at the same time, culturing strains in large containers requires a large amount of culture medium, and the strains grow unevenly, increasing the risk of contamination by foreign bacteria. Some overgrown strains will affect the growth of other strains. Utility Model Content

[0026] Below, a triple fermentation device is described in detail with reference to the accompanying drawings.

[0027] like Figure 1 As shown, the triple fermentation equipment mainly includes a fermentation tank, a steam generator 4 and a water purifier 5, wherein there are three fermentation tanks, which are connected in sequence and ferment step by step; each fermentation tank is provided with a fermentation chamber and a jacket, the jacket is located outside the fermentation chamber, the output end of the steam generator 4 is connected to the jacket, and high-temperature steam can be transported into the jacket to perform heating sterilization or heating temperature control cultivation in the fermentation chamber; the water purifier 5 has a pure water outlet and a waste water outlet, the water purifier 5 is connected to an external water source, the pure water outlet is connected to the fermentation chambers of the three fermentation tanks through corresponding pipelines, respectively, to provide suitable humidity for the cultivation of the strains, the waste water outlet is connected to the jackets of the fermentation tanks through corresponding pipelines, and the fermentation chamber is cooled by waste water.

[0028] Specifically, the three fermentation tanks are a primary fermentation tank 1, a secondary fermentation tank 2 and a tertiary fermentation tank 3, and are connected in sequence through pipelines, so that the primary fermentation tank 1 is connected with the secondary fermentation tank 2, and the bacteria cultured in the primary fermentation tank 1 can be put into the secondary fermentation tank 2, and the secondary fermentation tank 2 is connected with the tertiary fermentation tank 3, and the bacteria cultured in the secondary fermentation tank 2 can be put into the tertiary fermentation tank 3.

[0029] The fermentation tank is provided with a stirring mechanism, and a stirring rod of the stirring mechanism is located in the fermentation chamber to disturb the materials in the fermentation chamber. After the strains and culture medium are added, the culture medium and strains are stirred and agitated together as materials by the stirring rod to make them evenly mixed. The driving part of the stirring mechanism can be an electric motor, and the output end of the motor is connected to the stirring rod to realize stirring drive.

[0030] In addition, the fermentation tank is also provided with a detection port, through which the material in the fermentation chamber can be extracted for detection to understand the fermentation situation. In addition, corresponding detection elements can be installed on the detection port, such as air pressure sensors, temperature sensors, humidity sensors, pH sensors, etc., to measure the corresponding air pressure, temperature, humidity, pH value, etc., to obtain the environmental parameters in the fermentation chamber, and adjust the fermentation chamber according to the environmental parameters.

[0031] In this embodiment, the volumes of the corresponding fermentation chambers of the primary fermentation tank 1, the secondary fermentation tank 2, and the tertiary fermentation tank 3 are increased in sequence. For example, the volume of the fermentation chamber of the primary fermentation tank 1 is 100L, and the volume of the fermentation chamber of the secondary fermentation tank 2 is 1m 3 The fermentation chamber volume of the three-stage fermentation tank 3 is 5m 3 In other optional implementations, the capacity can be adjusted according to demand.

[0032] A three-stage fermentation tank is set up to cultivate the bacteria step by step to improve the uniformity of bacterial distribution and the consistency of growth rate, reduce the risk of contamination by foreign bacteria, add a steam generator 4 connected to the fermentation tank jacket, heat and sterilize the fermentation tank in advance, and control the temperature in the fermentation tank in combination with cooling water to provide a good environment for bacterial growth.

The return pipe is provided with a control valve and a return pump, which can return the fermented bacteria to the fermentation chamber of the upper fermentation tank for further cultivation, and the remaining bacteria are transported to the downstream fermentation chamber for cultivation, thereby realizing continuous fermentation and cultivation of the bacteria.

[0042] The pure water output by the water purifier 5 is used for bacterial culture, and the output waste water is supplied to the jacket for temperature regulation of the fermentation chamber.
