Technical Field

[0001] The utility model relates to the technical field of vinegar processing, in particular to fermentation equipment for vinegar production. Background Art

[0002] In the production process of vinegar, fermentation not only affects production efficiency, but also directly affects the quality and taste of the product. Traditional vinegar fermentation usually adopts an open fermentation system, such as pottery jars and wooden barrels, which makes it difficult to control the temperature, humidity and sanitary conditions during the fermentation process, which can easily lead to unstable product quality and even food safety issues.

[0003] However, in the fermentation equipment in the prior art, during the growth of microorganisms, the equipment often produces a large amount of bubbles and foam in combination with stirring. A large amount of bubbles and foam will hinder the gas exchange during the fermentation process and reduce the fermentation efficiency; bubbles and foam will also cause uneven distribution of nutrients in the fermentation liquid, resulting in some microorganisms unable to obtain sufficient nutrition, thereby affecting the fermentation quality.

[0004] Therefore, it is necessary to provide a fermentation device for vinegar production to solve the problems in the above-mentioned background technology. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features; in the description of this application, unless otherwise specified, "plurality" means two or more.

[0025] Figure 1-4 A fermentation device for producing vinegar provided in an embodiment of the present application includes: a fermentation tank 1, on which a cleaning and mixing mechanism 4 is provided, wherein the cleaning and mixing mechanism 4 includes a power motor 41 fixed to the upper end of the fermentation tank 1, and a rotating shaft 411 is fixed to the output end of the power motor 41, and a defoaming component 42 and a plurality of stirring components 43 are arranged on the rotating shaft 411 from top to bottom, and the defoaming component 42 includes a plurality of scrapers 421 arranged on the rotating shaft 411, and a plurality of defoaming pipes 5 are fixedly arranged on the fermentation tank 1 at a height corresponding to the scrapers 421.

[0026] Based on the above scheme, the fermentation raw materials of vinegar are placed in the fermentation tank 1, and the volume of the fermentation raw materials injected into the fermentation tank 1 is fixed. During the fermentation process, the power motor 41 is turned on, and the stirring component 43 stirs the fermented material in the fermentation tank 1. At the same time, when the defoaming component 42 is rotating, the scraper 421 scrapes the bubbles and foam under the action of centrifugal force and throws them into the foam discharge pipe 5 for processing, so that the bubbles and foam in the fermentation tank 1 can be quickly removed, the gas exchange efficiency in the fermentation tank 1 is improved, and the fermentation process is smoother. At the same time, the leaves help to make the nutrients in the fermentation liquid more uniform, promote the growth and metabolism of microorganisms, and thus improve the fermentation quality.

[0027] See also Figure 4In a possible implementation, the scraper 421 includes a plurality of wing blades 4211 fixedly disposed on the rotating shaft 411, and the wing blades 4211 are connected with built-in blades 4212 via telescopic springs.

[0028] Based on the above scheme, the wing blades 4211 and the built-in blades 4212 can rotate with the rotating shaft 411. The built-in blades 4212 can extend out of the wing blades 4211 through the extension of the telescopic spring during the rotation process. The built-in blades 4212 can also be contracted in the wing blades 4211 through the compression of the telescopic spring during the rotation process.

[0029] In one possible implementation, a feed pipe 2 and an exhaust port 3 are fixedly provided at the upper end of the fermentation tank 1. The feed pipe 2 introduces the raw materials to be fermented into the fermentation tank 1 for fermentation. The exhaust port 3 is mainly used to discharge carbon dioxide and other gases generated during the fermentation process, maintain ventilation in the fermentation tank 1, and prevent the tank from exploding due to excessive gas pressure.

[0030] In one possible implementation, a discharge pipe 6 is fixedly provided at the lower end of the fermenter 1, and a plurality of foot supports 7 are fixedly provided at the lower end of the fermenter 1. The discharge pipe 6 can discharge the fermentation product from the fermenter 1 through the discharge pipe 6 to facilitate subsequent separation, purification and production operations. The foot supports 7 can provide stable support for the fermenter 1 to prevent it from tilting or tipping over during use, thereby ensuring the safe operation of the equipment.

[0031] In one possible implementation, the interior of the fermentation tank 1 is a hollow tank body, and a plurality of arc-shaped bosses 11 are fixed inside the fermentation tank 1 at a height corresponding to the built-in leaves 4212, thereby ensuring that the built-in leaves 4212 can move along the arc-shaped bosses 11 during rotation.

[0032] See also Figure 3 In one possible implementation, the arc-shaped boss 11 includes an arc-shaped portion and a raised portion, and the foam discharge pipe 5 is fixedly provided on the fermentation tank 1 located at the raised portion, so that when the built-in leaf 4212 moves from the raised portion to the arc-shaped portion, the telescopic spring stretches, and the built-in leaf 4212 can quickly extend out of the wing leaf 4211.

[0033] In one possible implementation, the number of the arc-shaped bosses 11 is equal to the number of the foam discharge tubes 5, which is beneficial for the bubbles and foam there to generate a swinging force through the rapid deformation of the telescopic spring, so that the bubbles and foam moved from the raised part to the arc-shaped part are quickly bounced to the foam discharge tubes 5 and processed accordingly.

[0034] In a possible implementation, the stirring assembly 43 includes a plurality of stirring blades 431 fixed on the rotating shaft 411 .

[0035] Based on the above scheme, the stirring blade 431 can mix the gas with the fermentation product during rotation, so that oxygen can diffuse into the fermentation product more quickly, provide sufficient oxygen for microorganisms such as acetic acid bacteria, and promote the fermentation reaction. At the same time, it can make the fermentation product evenly distributed, avoid the formation of dead corners or lumps at the bottom or surface of the fermentation tank 1, ensure the uniformity of the entire fermentation process, and make the reaction rate more stable.

[0036] Working principle:

[0037] The feed pipe 2 is opened, and the fermented vinegar is placed in the fermentation tank 1, and the volume of the content injected into the fermentation tank 1 is fixed. During the fermentation process, the power motor 41 is turned on, and the stirring assembly 43 stirs the fermented product in the fermentation tank 1. At the same time, the wing blades 4211 of the scraper 421 drive the built-in blades 4212 to rotate and extend intermittently. The built-in blades 4212 can scrape bubbles and foam during the rotation along the arc-shaped boss 11, and the built-in blades 4212 throw the bubbles and foam to the foam discharge pipe 5 for processing when the raised part moves to the arc-shaped part.

[0038] The above embodiments are only used to illustrate the technical solution of the present application, but not to limit it. The present application is not limited to the exact structure described above and illustrated in the accompanying drawings, and it cannot be determined that the specific implementation of the present application is limited to these descriptions. For ordinary technicians in the technical field to which the present application belongs, various changes and modifications made without departing from the concept of the present application should be deemed to belong to the protection scope of the present application.
