[0002] In the fields of food, biological engineering and pharmaceuticals, multi-strain fermentation technology is widely used in the production of various fermented products, such as wine, vinegar, yogurt, antibiotics, etc. Traditional multi-strain fermentation process usually requires separate cultivation of different strains, and then the strains are mixed with raw materials for fermentation. However, this step-by-step operation not only has low efficiency, but also is prone to contamination or imbalance of strain ratio due to improper operation, affecting the quality and stability of the final product.

[0003] Most of the existing fermentation equipment is designed for single strain, and it is difficult to realize synchronous fermentation of multiple strains.

[0060] S5. Mix the raw materials with one of the acetic acid or alcohol;

[0061] S6. Transfer the mixed liquid into the fermentation tank for fermentation.

[0062] Working principle of the present application:

[0063] The cleaning cylinder 202 is filled with clean water. The raw materials are put into the cleaning cylinder 202 from the feeding hopper 207 and fall on the cleaning disc 213. The lifting motor 210 drives the screw rod 212 to rotate, thereby driving the cleaning disc 213 to rotate. Under the cooperation of the inner thread sleeve 214 and the screw rod 212, the lifting disc 208 and the pressing disc 209 are lifted along the fixed column 206, so that the cleaning disc 213 is lifted spirally. The cleaning disc 213 is first lifted spirally, thereby driving the raw materials to be cleaned in the cleaning cylinder 202. When the cleaning disc 213 reaches the ejection groove of the cleaning cylinder 202, the raw materials on the cleaning disc 213 are ejected into the ejection disc 204. The holes on the cleaning disc 213 do not take away too much water when the cleaning disc 213 leaves the water surface. When the lifting disc 208 is lowered, the raw materials in the ejection disc 204 are extruded by the pressing disc 209, so that the water in the raw materials in the ejection disc 204 is extruded into the water outlet disc 203 through the holes of the ejection disc 204, and finally flows out from the drain pipe 219, and the raw materials are crushed by the pressing disc 209. The scraping motor 216 drives the scraping gear 217 to rotate, and under the cooperation of the scraping gear 217 and the fixed gear 218, the scraping plate 215 moves along the ejection disc 204, thereby pushing the crushed raw materials on the ejection disc 204 into the discharge pipe 211, and the scraping plate 215 scrapes the water on the lower surface of the ejection disc 204 and flows into the water outlet disc 203. The raw materials enter the left through hole 3062 through the discharge pipe 211. The feeding motor 303 drives the feeding gear 304 to rotate, thereby driving the partial gear 302, the rotating disc 301 and the rotating feeding disc 306 to rotate, so that the left through hole 3062 reaches above the left feeding hole 3052. The raw materials enter the lower fermentation cylinder 103 through the left feeding hole 3052. At the same time, the right through hole 3061 reaches below the discharge pipe 211. The raw materials in the discharge pipe 211 enter the right through hole 3061. Then the feeding motor 303 is reversed, so that the right through hole 3061 reaches above the right feeding hole 3051. The raw materials enter the lower fermentation cylinder 103 through the right feeding hole 3051. At the same time, the left through hole 3062 reaches below the discharge pipe 211. The raw materials enter the left through hole 3062. When the right through hole 3061 and the left through hole 3062 move, the lower part is closed by the fixed feeding disc 305, and the lower part of the discharge pipe 211 is closed by the rotating feeding disc 306. In this way, the equal amount of raw materials is put into the fermentation cylinder 103. The rotating motor 105 drives the motor gear 106 to rotate, thereby driving the two rotating discs 102 to rotate at the same time for one hundred and twenty degrees, so that the two fermentation cylinders 103 into which the raw materials are just put reach below the two discharge cylinders 116.In the initial state, the two discharge cylinders 116 close the adding box 107, then the discharge cylinder 115 is retracted, the feeding gap 117 enters the adding box 107, at this time the acetic acid and alcohol in the adding box 107 enter the discharge cylinder 116 through the feeding gap 117 respectively, then flow out from the end of the discharge cylinder 116 into the two fermentation cylinders 103, the acetic acid and alcohol are added into the two fermentation cylinders 103 containing raw materials respectively, then the rotating disc 102 rotates 120 degrees, the two fermentation cylinders 103 reach above the jacking column 114, the electric cylinder 108 is retracted, drives the lifting plate 113 and the jacking column 114 to rise, the jacking column 114 jacks up the closing plug 109, the jacking spring 110 is compressed, the liquid in the fermentation cylinder 103 flows out through the outflow cylinder 111 to the outflow slope 112, then flows to the external fermentation tank for fermentation.

[0064] The above merely describes the preferred embodiments of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art, according to the technical solution and the inventive concept of the present application, makes equivalent replacement or change within the technical scope of the present application, should be covered within the protection scope of the present application.
